Hepatic ischemia/reperfusion (I/R) damage is one of the most common side effects of liver surgery. This pathophysiological process may lead to excessive hepatic damage. Aloperine is an active ingredient isolated from Sophora alopecuroides Linn and has a variety of therapeutic effects, including organ protection. However, the hepatoprotective effect of aloperine against hepatic I/R damage has not yet been determined. C57BL/6 mice were allocated to the sham-operated (sham), hepatic ischemia/reperfusion (I/R), and aloperine groups. The mice were exposed to 30 min of hepatic hilum occlusion. Then a 3-h reperfusion was performed. Mice in the sham group underwent sham surgery. Hepatic injury was evaluated by plasma aspartate aminotransferase (AST) and transaminase alanine aminotransferase (ALT) levels, histological evaluation, cell apoptosis, the number of activated inflammatory cells, and the expression levels of inflammatory cytokines, including tumor necrosis factor- α and interleukin-6. The protein phosphorylation status of the reperfusion-associated survival pathways was evaluated. Mice with hepatic I/R injury presented increased plasma ALT and AST levels, increased hepatic apoptosis, abnormal histological structure, and elevated inflammatory responses. However, aloperine ameliorated hepatic I/R-induced injury. Moreover, aloperine enhanced the level of signal transducer and activator of transcription (STAT)-3 phosphorylation after I/R. Ag490, an agent that inhibits STAT-3 activity, abolished aloperine-induced STAT-3 phosphorylation and liver protection. Aloperine ameliorates hepatic I/R-induced liver injury via a STAT-3-mediated protective mechanism. Patients with hepatic I/R injury may benefit from aloperine treatment. SIGNIFICANCE STATEMENT: Hepatic I/R can cause excessive liver damage. This study revealed that aloperine, an active component isolated from Sophora alopecuroides Linn, ameliorates hepatic I/R injury and related liver damage in vivo. The underlying protective mechanism may involve the STAT-3 signaling pathway. These findings may lead to the development of a novel approach for treating hepatic I/R damage in clinical practice., (Copyright © 2024 by The American Society for Pharmacology and Experimental Therapeutics.)

Background: Juvenile Dermatomyositis (JDM) is a rare disorder with subtypes associated with different myositis-specific antibodies (MSAs) including anti-MDA5. Hepatic involvement in JDM is rare and has not previously been documented in anti-MDA5 JDM. There is a lack of formal research on treatment protocols for anti-MDA5 JDM, though tofacitinib is a highly regarded emerging therapy., Case Presentation: A previously healthy 14-month-old Hispanic female presented to a pediatric rheumatology clinic with eight months of worsening rash, weakness, periorbital edema, intermittent fevers, and weight loss. Her physical exam was notable for fever, thinning of hair, heliotrope rash, periorbital edema, violaceous macules on her bilateral elbows, forearms, arms, and knees, arthritis, Gottron's sign, and hepatomegaly. The patient was admitted, and symptoms progressed to include hypoxemia. Subsequent workup was notable for ground glass opacities of bilateral lung fields on chest CT, myositis visualized on MRI and confirmed with muscle biopsy, and liver biopsy showing nonspecific signs of liver injury. After a thorough infectious disease workup to rule out concomitant infection, the patient was started on high-dose steroids and induction with cyclophosphamide. She responded well with disease remission maintained with tofacitinib in the outpatient setting., Discussion and Conclusions: Our patient is notable due to her young age at presentation, histopathologically confirmed liver injury, and response to treatment. The case adds to the growing body of literature supporting tofacitinib for anti-MDA5 JDM in the pediatric population. Future research can better standardize effective treatment protocols and define the mechanism of liver involvement. For patients with nonspecific liver injury, muscular, and cutaneous disease, anti-MDA5 JDM should be considered in the differential diagnosis with treatment options including tofacitinib for confirmed cases., (© 2024.

Background: For treating patients with refractory chronic spontaneous urticaria (CSU) resistant to standard doses of 2 nd generation H1-antihistamines (H1AH) the International and Japanese guidelines recommend increasing H1AH dose. The latter also recommends switching to a different H1AH. This study explored if the efficacy of the standard dose of bilastine 20 mg is non-inferior to that of double-dose of H1AH in patients with refractory CSU., Methods: This phase IV, multicenter, open-label, randomized, parallel-group trial evaluated the efficacy and safety of switching treatment to bilastine compared to treatment with a 2-fold dose of H1AH in patients with CSU refractory to standard dose H1AH. The primary endpoint was the mean total symptom score (TSS) at Day 5-7 after the start of administration., Results: Treatment efficacy and safety were evaluated in 128 patients (bilastine, n=64; 2-fold dose of H1AH, n=64). The mean TSS at Day 5-7 after the start of administration was smaller than the non-inferiority margin of 0.8, demonstrating non-inferiority of the bilastine switching group to the double-dose H1AH group (0.17 (95% CI -0.32, 0.67)). No difference in Japanese version of Epworth Sleepiness Scale (JESS), DLQI, and urticaria activity score over 7 consecutive days (UAS7) was observed between the two groups. There were no serious adverse events in either group. H1AH-related adverse events occurred in 5 subjects (8 cases) and 2 subjects (3 cases) in the double-dose H1AH and bilastine groups, respectively., Conclusions: Switching treatment to bilastine demonstrated non-inferiority to a double-dose of H1AH in terms of efficacy in patients with CSU refractory to standard dose H1AH with a favorable safety profile., Clinical Trial Registration: https://jrct.niph.go.jp/latest-detail/jRCTs051180105, identifier jRCTs051180105., Competing Interests: AF reports study grants and honoraria from Novartis and Taiho, and honoraria as a speaker from Sanofi, Kyowa Kirin, Kyorin, Mitsubishi-Tanabe, and Kaken Pharmaceutical.

A 36-year-old man with inverse Gottron's sign was admitted for clinically amyopathic dermatomyositis (CADM) with rapidly progressive interstitial lung disease (RP-ILD). Early addition of plasma exchange (PE) to triple therapy improved severe respiratory failure and transiently decreased serum ferritin levels and anti-melanoma differentiation-associated gene 5 antibody (anti-MDA5 Ab) titers. Furthermore, switching from tacrolimus to tofacitinib resulted in disease remission. Recognition of the inverse Gottron's sign may allow for the earlier diagnosis of anti-MDA5 Ab-positive dermatomyositis, and early addition of PE to triple therapy and administration of tofacitinib in refractory cases may be effective for anti-MDA5 Ab-positive CADM with RP-ILD under life-threatening conditions.

Background: Postoperative ileus (POI) is a common complication following abdominal surgery, often leading to extended hospital stays and a higher risk of post-operative complications, leading to poorer patient outcomes. Alvimopan, a peripherally acting µ-opioid receptor antagonist, has been shown to aid in the recovery of normal bowel function after surgery. While its benefits are well-established in open abdominal surgeries, its efficacy in laparoscopic procedures had not been conclusively determined. However, recent clinical trials involving laparoscopic surgeries have since been conducted. This review aims to reassess the efficacy of Alvimopan by incorporating findings from these new studies, potentially providing further insight into its clinical benefits., Methods: A comprehensive search of PubMed, Google Scholar, EMBASE, and the Cochrane Library was conducted. Studies were included based on the PICO framework, focusing on Alvimopan's impact on postoperative gastrointestinal recovery. Primary outcomes were time to gastrointestinal function recovery (GI-3) and hospital stay duration., Results: Ten studies met the inclusion criteria, with seven focusing on the use of Alvimopan in open abdominal surgeries and three in laparoscopic procedures. Collectively, these studies involved 18,822 patients undergoing various types of abdominal Administration of Alvimopan 6 mg accelerated gastrointestinal function recovery by an average of 14 h (Hazard ratio: 1.62, p = 0.002) and reduced hospital stays by 5.2 h (Hazard ratio: 1.52, p = 0.04) compared to placebo. Similarly, Alvimopan 12 mg reduced GI-3 recovery time by 13.5 h (Hazard ratio: 1.58, p = 0.02) and hospital stay duration by 6.2 h (Hazard ratio: 1.46, p = 0.018)., Conclusion: Alvimopan shows promise in reducing POI and hospital stay durations following abdominal surgeries. The incorporation of the recent studies in laparoscopic abdominal procedures further supports these findings. Integrating Alvimopan into perioperative care protocols may enhance patient outcomes and help lower healthcare costs., (© 2024. Crown.)

Purpose: Ibrutinib is a first-in-class inhibitor of Bruton tyrosine kinase. We previously reported the safety and short-term antitumor activity of ibrutinib in 20 patients with relapsed or refractory (r/r) primary central nervous system (CNS) lymphoma (PCNSL) or secondary CNS lymphoma (SCNSL)., Patients and Methods: We enrolled 26 additional patients with r/r PCNSL/SCNSL into the dose-expansion cohort of the trial into a combined cohort of 46 patients (31 with PCNSL and 15 with SCNSL). Patients received ibrutinib at 560 or 840 mg daily in the dose-escalation cohort and ibrutinib at 840 mg daily in the expansion cohort. The median follow-up was 49.9 and 62.1 months for patients with PCNSL and SCNSL, respectively. We sequenced DNA from available tumor biopsies and cerebrospinal fluid collected before and during ibrutinib therapy., Results: Tumor responses were observed in 23/31 (74%) patients with PCNSL and 9/15 (60%) patients with SCNSL, including 12 complete responses in PCNSL and 7 in SCNSL. The median progression-free survival (PFS) for PCNSL was 4.5 months [95% confidence interval (CI), 2.8-9.2] with 1-year PFS at 23.7% (95% CI, 12.4%-45.1%). The median duration of response in the 23 PCNSL responders was 5.5 months. The median PFS in SCNSL was 5.3 months (95% CI, 1.3-14.5) with a median duration of response of 8.7 months for the 9 responders. Exploratory biomarker analysis suggests that mutations in TBL1XR1 may be associated with a long-term response to ibrutinib in PCNSL (P = 0.0075). Clearance of ctDNA from cerebrospinal fluid was associated with complete and long-term ibrutinib responses., Conclusions: Our study confirms single-agent activity of ibrutinib in r/r CNS lymphoma and identifies molecular determinants of response based on long-term follow-up., (©2024 American Association for Cancer Research.)

Triple-negative breast cancer (TNBC) is the most aggressive subtype of breast cancer, and STAT3 has emerged as an effective drug target for TNBC treatment. Herein, we employed a scaffold-hopping strategy of natural products to develop a series of naphthoquinone-furopiperidine derivatives as novel STAT3 inhibitors. The in vitro assay showed that compound 10g possessed higher antiproliferative activity than Cryptotanshinone and Napabucasin against TNBC cell lines, along with lower toxicity and potent antitumor activity in a TNBC xenograft model. Mechanistically, 10g could inhibit the phosphorylation of STAT3 and the binding affinity was determined by the SPR assay ( K D = 8.30 μM). Molecule docking studies suggested a plausible binding mode between 10g and the SH2 domain, in which the piperidine fragment and the terminal hydroxy group of 10g played an important role in demonstrating the success of this evolution strategy. These findings provide a natural product-inspired novel STAT3 inhibitor for TNBC treatment.

Background: Glioblastoma is a highly malignant disease with limited treatment options. Ibrutinib, a covalent Bruton tyrosine kinase inhibitor, is an oral agent with manageable side effects used for hematological diseases including Waldenström macroglobulinemia. We present the case of a 69-year-old Caucasian male patient treated with ibrutinib for suspected Bing-Neel syndrome (BNS), which following a biopsy, was reclassified as glioblastoma., Case Presentation: In December 2018, a 69-year-old Caucasian male patient was diagnosed with Waldenström macroglobulinemia. As the patient was asymptomatic, without bone marrow failure or high M-component count, watchful waiting was initiated. Due to increasing neurological symptoms, the patient, based on magnetic resonance imaging, was diagnosed with Bing-Neel syndrome in May 2019. The patient received different treatments before starting ibrutinib monotherapy in August 2019 due to disease progression, both on magnetic resonance imaging and clinically. The patient remained clinically stable for 7 months. In March 2020, the patient developed headaches, and both magnetic resonance imaging and a biopsy revealed glioblastoma IDH-wildtype. Treatment was changed in line with the new diagnosis, but the patient died at the end of 2020., Conclusion: We present a case in which a patient with glioblastoma IDH-wildtype remained clinically stable for 7 months when treated with ibrutinib monotherapy, which is similar to what would be expected for the standard treatment for glioblastoma. To our knowledge, this is the first patient receiving ibrutinib for a glioblastoma IDH-wildtype with a meaningful clinical outcome. Our case may therefore support previous nonclinical findings, indicating a therapeutic value of ibrutinib in patients with glioblastoma and support for further investigation of ibrutinib as a possible treatment for glioblastoma., (© 2024.

Abstract: Covalent Bruton tyrosine kinase inhibitors (cBTKis), which bind to the BTK C481 residue, are now primary therapeutics for chronic lymphocytic leukemia (CLL). Alterations at C481, primarily C481S, prevent cBTKi binding and lead to the emergence of resistant clones. Pirtobrutinib is a noncovalent BTKi that binds to both wild-type (WT) and C481S-mutated BTK and has shown efficacy in BTK-WT and -mutated CLL patient groups. To compare baseline clinical, transcriptomic, and proteomic characteristics and their changes during treatment in these 2 groups, we used 67 longitudinal peripheral blood samples obtained during the first 3 cycles of treatment with pirtobrutinib from 18 patients with CLL (11 BTK-mutated, 7 BTK-WT) enrolled in the BRUIN (pirtobrutinib in relapsed or refractory B-cell malignancies) trial. Eastern Cooperative Oncology Group performance status, age, and Rai stage were similar in both groups. At baseline, lymph nodes were larger in the BTK-mutated cohort. All patients achieved partial remission within 4 cycles of pirtobrutinib. Lactate dehydrogenase and β2-microglobulin levels decreased in both cohorts after 1 treatment cycle. Expression analysis demonstrated upregulation of 35 genes and downregulation of 6 in the BTK-mutated group. Gene set enrichment analysis revealed that the primary pathways enriched in BTK-mutated cells were involved in cell proliferation, metabolism, and stress response. Pathways associated with metabolism and proliferation were downregulated in both groups during pirtobrutinib treatment. Proteomic data corroborated transcriptomic findings. Our data identified inherent differences between BTK-mutated and -WT CLL and demonstrated molecular normalization of plasma and omics parameters with pirtobrutinib treatment in both groups., (© 2024 by The American Society of Hematology.

Background: We report the final results of treatment with aripiprazole, blonanserin, and paliperidone from the Japan Useful Medication Program for Schizophrenia (JUMPs), a 104-week naturalistic study., Methods: JUMPs was an open-label, three-arm, randomized, parallel-group, 104-week study. Patients aged ≥ 20 years with schizophrenia requiring antipsychotic treatment or a switch from previous therapy were enrolled. The primary endpoint was treatment discontinuation rate over 104 weeks. Secondary endpoints included remission rate, Personal and Social Performance (PSP), safety, Positive and Negative Syndrome Scale (PANSS), and quality of life (QOL; EuroQol-5 dimension)., Results: In total, 251 patients received aripiprazole (n = 82), blonanserin (n = 85), or paliperidone (n = 84). Treatment discontinuation rates (aripiprazole, 80.5%; blonanserin, 81.2%; paliperidone, 71.4%) were not significantly different (p = 0.2385) among the treatment groups at 104 weeks; comparable outcomes were observed for endpoints, including remission (42.9%, 46.7%, and 45.8%), PANSS, and safety. In the overall cohort, while the improvement in the PSP total score at Week 104 was not significantly different from baseline, a significant improvement (p < 0.05) in QOL and total PANSS scores (including all subscales) was observed at Week 104 compared with baseline. Multivariable analysis identified a shorter disease duration and a higher chlorpromazine-equivalent antipsychotic dosage level (≥ 1000 mg) before switching to monotherapy as predictors of treatment discontinuation., Conclusions: The 104-week treatment outcomes were comparable between groups; the overall trend of improvement in remission rate, safety, and QOL suggests the importance of continued treatment., Clinical Trial Registration: UMIN-Clinical Trials Registry UMIN000007942 (public release date: 14/05/2012)., (© 2024.

Homologous recombination deficiency (HRD) is prevalent in cancer, sensitizing tumor cells to poly (ADP-ribose) polymerase (PARP) inhibition. However, the impact of HRD and related therapies on the tumor microenvironment (TME) remains elusive. Our study generates single-cell gene expression and T cell receptor profiles, along with validatory multimodal datasets from >100 high-grade serous ovarian cancer (HGSOC) samples, primarily from a phase II clinical trial (NCT04507841). Neoadjuvant monotherapy with the PARP inhibitor (PARPi) niraparib achieves impressive 62.5% and 73.6% response rates per RECIST v.1.1 and GCIG CA125, respectively. We identify effector regulatory T cells (eTregs) as key responders to HRD and neoadjuvant therapies, co-occurring with other tumor-reactive T cells, particularly terminally exhausted CD8 + T cells (Tex). TME-wide interferon signaling correlates with cancer cells upregulating MHC class II and co-inhibitory ligands, potentially driving Treg and Tex fates. Depleting eTregs in HRD mouse models, with or without PARP inhibition, significantly suppresses tumor growth without observable toxicities, underscoring the potential of eTreg-focused therapeutics for HGSOC and other HRD-related tumors., Competing Interests: Declaration of interests Y.Y., Y.D., Y.Z., X.H., and X.

Abstract: Chronic lymphocytic leukemia (CLL) progression during Bruton tyrosine kinase (BTK) inhibitor treatment is typically characterized by emergent B-cell receptor pathway mutations. Using peripheral blood samples from patients with relapsed/refractory CLL in ELEVATE-RR (NCT02477696; median 2 prior therapies), we report clonal evolution data for patients progressing on acalabrutinib or ibrutinib (median follow-up, 41 months). Paired (baseline and progression) samples were available for 47 (excluding 1 Richter) acalabrutinib-treated and 30 (excluding 6 Richter) ibrutinib-treated patients. At progression, emergent BTK mutations were observed in 31 acalabrutinib-treated (66%) and 11 ibrutinib-treated patients (37%; median variant allele fraction [VAF], 16.1% vs 15.6%, respectively). BTK C481S mutations were most common in both groups; T474I (n = 9; 8 co-occurring with C481) and the novel E41V mutation within the pleckstrin homology domain of BTK (n = 1) occurred with acalabrutinib, whereas neither mutation occurred with ibrutinib. L528W and A428D comutations presented in 1 ibrutinib-treated patient. Preexisting TP53 mutations were present in 25 acalabrutinib-treated (53.2%) and 16 ibrutinib-treated patients (53.3%) at screening. Emergent TP53 mutations occurred with acalabrutinib and ibrutinib (13% vs 7%; median VAF, 6.0% vs 37.3%, respectively). Six acalabrutinib-treated patients and 1 ibrutinib-treated patient had emergent TP53/BTK comutations. Emergent PLCG2 mutations occurred in 3 acalabrutinib-treated (6%) and 6 ibrutinib-treated patients (20%). One acalabrutinib-treated patient and 4 ibrutinib-treated patients had emergent BTK/PLCG2 comutations. Although common BTK C481 mutations were observed with both treatments, patterns of mutation and comutation frequency, mutation VAF, and uncommon BTK variants varied with acalabrutinib (T474I and E41V) and ibrutinib (L528W and A428D) in this patient population. The trial was registered at www.clinicaltrials.gov as #NCT02477696., (© 2024 American Society of Hematology. Published by Elsevier Inc.

Background: The management of inflammatory bowel disease [IBD] patients with concurrent liver transplantation is challenging, and data regarding the safety and efficacy of Janus kinase [JAK] inhibitors with anti-rejection medications are required. We report the experience of all liver transplant recipients receiving tofacitinib and/or upadacitinib for IBD across three states in Australia., Methods: All liver transplant recipients from the Australian states of Victoria, New South Wales, and Tasmania, who required tofacitinib or upadacitinib for the treatment of IBD, were identified using prospectively maintained liver transplant databases. Patients were followed up until medication cessation or last follow-up. Clinical safety and efficacy data were collected., Results: Eight patients [median age 30 years] were included, seven of whom received first-line JAK inhibition with tofacitinib. All patients had failed one or more biologic therapies prior to commencing JAK inhibition, including six patients who had failed two or more agents. JAK inhibition was continued for a median of 17 months, with 143 patient-months of combined follow-up. The anti-rejection medication tacrolimus was prescribed in all patients. Overall, seven [88%] patients achieved clinical remission, including all three patients who were switched from tofacitinib to upadacitinib. One patient required colectomy after 1 month of treatment. There were no other cases of serious infection, venous thromboembolism, or major adverse cardiovascular events during follow-up., Conclusions: As the largest case series to date, these data indicate that combining JAK inhibition with transplant anti-rejection medication may be a safe and clinically effective method of treating IBD in patients with prior biologic failure., (© The Author(s) 2024.

Patients on B cell immunosuppressive treatments have been shown to have persistent infection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). In this report, a woman treated with ibrutinib for chronic lymphocytic leukemia experienced more than 40 days of coronavirus disease 2019 (COVID-19) infection. Unexpectedly, her peripheral blood experiments showed a normal SARS-CoV-2-specific antibody level and a relatively elevated percentage of CD19 + B cells, while an obvious decrease in the percentages of NK cells, CD4 + T cells and CD8 + T cells. Further SARS-CoV-2-specific T cell analysis in this patient indicated a significant decrease in the percentage of SARS-CoV-2-specific IFN-γ, TNF-α or IL-2 producing CD4 + T or CD8 + T cells. Most notably, ten days after the cease of ibrutinib, the PCR for SARS-CoV-2 turned negative and the reduced proportions of peripheral CD4 + T cells and CD8 + T cells recovered. Our research predicted that the depleted B-cell function therapies may play considerable role in the development of long COVID-19 and the abnormal T-cell subset distribution might be the underlying mechanism., (© 2024.

Purpose: This retrospective real-world study compared overall survival (OS) between patients with BRCA wild-type (BRCAwt) recurrent epithelial ovarian cancer (OC) who received niraparib second-line maintenance (2LM) versus active surveillance (AS) using target trial emulation, cloning, inverse probability of censoring weighting (IPCW) methodology to minimize immortal time bias., Methods: Eligible patients from a United States-based, deidentified, electronic health record-derived database were diagnosed with epithelial OC (January 1, 2011-May 31, 2021), were BRCAwt, and completed second-line (2L) therapy (January 1, 2017-March 2, 2022). Patient data were cloned at index (2L last treatment date), assigned to niraparib 2LM and AS cohorts, and censored when treatment deviated from clone assignment. Follow-up was measured from index to earliest of study end (May 31, 2022), last activity, or death. Median OS (mOS) and hazard ratios were estimated from stabilized IPCW Kaplan-Meier curves and Cox regression models., Results: Overall, 199 patients received niraparib 2LM, and 707 had their care managed with AS. Key characteristics were balanced across cohorts after cloning and stabilized IPCW. Median follow-up was 15.6- and 9.3-months pre-cloning. IPCW mOS was 24.1 months (95% CI: 20.9-29.5) and 18.4 months (95% CI: 15.1-22.8) in niraparib 2LM and AS cohorts, respectively (hazard ratio, 0.77; 95% CI: 0.66-0.89)., Conclusions: This real-world study provides supportive evidence of an OS benefit for patients with BRCAwt recurrent OC who received 2LM niraparib monotherapy compared with those whose care was managed with AS. The analytic strategies implemented were useful in minimizing immortal time bias and measured confounding., (© 2024 The Author(s).

Objective: To evaluate the long-term efficacy and safety of niraparib in Japanese women with heavily pretreated ovarian cancer., Methods: This was the follow-up analysis of a phase 2, multicenter, open-label, single-arm study in Japanese women with homologous recombination-deficient, platinum-sensitive, relapsed, high-grade serous epithelial ovarian, fallopian tube, or primary peritoneal cancer who had completed 3-4 lines of chemotherapy and were poly(ADP-ribose) polymerase inhibitor naïve. Participants received niraparib (starting dose, 300 mg) once daily in continuous 28-day cycles until objective disease progression, unacceptable toxicity, or consent withdrawal. The primary endpoint was confirmed objective response rate (ORR), as assessed using Response Evaluation Criteria in Solid Tumors version 1.1. Safety evaluations included treatment-emergent adverse events (TEAEs)., Results: 20 patients were enrolled in the study and included in both efficacy and safety analyses. Median total study duration was 759.5 days. Median dose intensity was 201.3 mg/day. Confirmed ORR was 60.0% (90% confidence interval [CI]=39.4-78.3); 2 patients had complete response and 10 patients had partial response. Median duration of response was 9.9 months (95% CI=3.9-26.9) and the disease control rate was 90.0% (95% CI=68.3-98.8). The most common TEAEs were anemia (n=15), nausea (n=12), and decreased platelet count (n=11). TEAEs leading to study drug dose reduction, interruption, or discontinuation were reported in 16 (80.0%), 15 (75.0%), and 2 patients (10.0%), respectively., Conclusion: The long-term efficacy and safety profile of niraparib was consistent with previous findings in the equivalent population in non-Japanese patients.

Background: Effectiveness and safety of advanced therapies for ulcerative colitis (UC) warrant assessment in the real world., Objective: To perform a systematic review and summarize real-world evidence of advanced therapies approved for moderate-to-severe UC., Methods: A systematic literature review was conducted using real-world studies of biologics or small molecules in UC using Embase, MEDLINE, and MEDLINE-In Process databases. Only products approved in any jurisdiction during the search were included. English-language full-papers (January 2005 to February 2022) and congress abstracts (January 2019 to February 2022) were included. Studies with less than 30 patients or only biologic-naive patients were excluded., Results: A total of 139 studies were included out of 3,930 identified articles (75%, published between 2019 and 2022; 64%, retrospective observational; 53%, from 5 countries [Italy, United States, Spain, United Kingdom, and Belgium]). Most studies were single agent (highest: vedolizumab = 50, tofacitinib = 24, and adalimumab = 18), and rates of clinical remission (CR) and adverse events varied widely. From the published comparative effectiveness studies (16), the rates of CR were numerically higher with vedolizumab vs anti-tumor necrosis factor (TNF)-α agents. Compared with vedolizumab, the effectiveness of tofacitinib was numerically greater in CR (occasionally significant). Rates of steroid-free CR were comparable between ustekinumab and tofacitinib. Infliximab was the most effective anti-TNFα agent, as reported by 2 studies. Remarkably, adverse events were similar across therapies in comparative studies., Conclusions: Vedolizumab and tofacitinib were the most assessed therapies. In comparative studies, remission rates were numerically higher with tofacitinib vs vedolizumab and for vedolizumab vs anti-TNFα. Tofacitinib was comparable with ustekinumab for steroid-free CR. Safety was comparable across therapies. Future studies should explore the literature gaps identified, including limited comparative studies with small sample sizes, variations in study designs and patient characteristics, varied definitions of CR, and limited use of patient-reported outcome measures in real-world settings.

Introduction: Rheumatoid arthritis (RA) is a chronic systemic autoimmune disease characterized by synovial inflammation, joint swelling, and pain involving multiple joints. While biologic disease-modifying antirheumatic drugs (bDMARDs) and targeted synthetic DMARDs (tsDMARDs) are popular treatments for RA, there is limited research on their combined use. This study examined a cohort of RA patients who demonstrated inadequate response to bDMARDs and subsequently initiated combination therapy with tofacitinib and bDMARDs, assessing both the efficacy and safety profile of this therapeutic approach., Methods: In this study, we retrospectively collected the electronic medical records (EMR) of 62 adult patients with RA who were admitted to the Fourth Affiliated Hospital Zhejiang University School of Medicine between August 2018 and December 2022. All patients had received at least one bDMARD treatment for more than 3 months and still exhibited moderate-to-high disease activity. Tofacitinib 5 mg bid was added to their original biological treatment in 28 cases, and other 34 cases switched to another bDMARD or tsDMARD as control group. Treatment was continued for 24 weeks following the initiation of combination therapy. Changes in DAS28-ESR and ACR20, 50, 70 response rates at week 24 were collected and analyzed from baseline, while changes in C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) at weeks 4, 8, 12, 24 were also collected and analyzed., Results: After 24 weeks of treatment, the DAS28-ESR score in combined treatment group decreased significantly from a baseline of 5.26 ± 0.90 (3.87-8.31) to 2.67 ± 0.86 (1.41-5.11), with remission achieved by 19 patients (67.9%) and low disease activity achieved by five patients (17.9%). The DAS28-ESR in the control group exhibited a decrease from 5.20 ± 0.77 (3.87-7.23) at baseline to 3.25 ± 1.29 (1.54-5.69). In all, 13 patients (38.2%) achieved remission, while another 11 patients (32.4%) achieved low disease activity. The ACR20, 50, 70 response rates were 85.71%, 75%, and 39.29% in the combined treatment group, whereas it were 75.0%, 53.57%, 21.43% in the control group. Additionally, both ESR and CRP levels decreased significantly during the course of treatment without any reported adverse events leading to discontinuation., Conclusion: Our findings offer some evidence, supporting the effectiveness and safety of combining bDMARD with JAKi tofacitinib in RA patients who have an inadequate response to bDMARD monotherapy. This combination effectively manages disease activity while maintaining a relatively low and manageable incidence of adverse events. Further prospective randomized controlled trials with large sample sizes are anticipated to provide evidence-based medical support., (© 2024 Asia Pacific League of Associations for Rheumatology and John Wiley & Sons Australia, Ltd.)

Introduction: With multiple targeted therapies approved for anaplastic lymphoma kinase (ALK)-positive metastatic non-small cell lung cancer (NSCLC), it is increasingly important to understand outcomes with various sequences of next-generation ALK tyrosine kinase inhibitors (TKIs). We describe contemporary sequencing patterns and treatment effectiveness of first-line (1L) and second-line (2L) treatments in patients who received second-generation ALK TKIs in the 1L treatment of ALK-positive NSCLC in the United States., Methods: A cohort of adults with ALK-positive advanced NSCLC who initiated treatment with 1L alectinib or brigatinib between June 2017 and April 2021 in the Flatiron Health electronic health record-derived de-identified database were followed through April 2023. Time to treatment discontinuation (TTD) in 1L and 2L, TTD on 1L plus 2L sequential therapy (TTD2), and total time on sequential ALK TKI therapy (including beyond 2L) were evaluated., Results: Patients (N=273) were followed up for a median duration of 28.9 months. Among patients who discontinued 1L therapy, 22% died after 1L discontinuation (median time from discontinuation to death, 4.0 months) without receiving 2L therapy. Median (95% confidence interval [CI]) TTD was 21.9 (15.2-25.8) and 7.3 (5.3-10.2) months in 1L and 2L, respectively. Median (95% CI) TTD2 was 29.4 (25.1-36.1) months and total time on sequential ALK TKI treatment was 28.0 (23.6-32.9) months., Conclusions: In this large real-world study, TTD2 and the total time on sequential ALK TKIs was approximately 2.5 years. The high attrition rate from 1L to 2L and the longest clinical benefit observed with 1L therapy support using the drug with the longest 1L effectiveness up front in patients with ALK-positive advanced NSCLC., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Dr. Bauman reports consulting fees from EMD Serono and participation on an advisory board for BeiGene, Blueprint Medicine, Janssen, Lilly, Merck, Mirati, Pfizer, and Turning Point Therapeutics.

As persistent elevation of transforming growth factor-β (TGF-β) promotes fibrosis of muscles and joints and accelerates disease progression in amyotrophic lateral sclerosis (ALS), we investigated whether inhibition of TGF-β would be effective against both exacerbations. The effects of TGF-β and its inhibitor on myoblasts and fibroblasts were tested in vitro and confirmed in vivo, and the dual action of a TGF-β inhibitor in ameliorating the pathogenic role of TGF-β in ALS mice was identified. In the peripheral neuromuscular system, fibrosis in the muscles and joint cavities induced by excessive TGF-β causes joint contracture and muscular degeneration, which leads to motor dysfunction. In an ALS mouse model, an increase in TGF-β in the central nervous system (CNS), consistent with astrocyte activity, was associated with M1 microglial activity and pro-inflammatory conditions, as well as with neuronal cell death. Treatment with the TGF-β inhibitor halofuginone could prevent musculoskeletal fibrosis, resulting in the alleviation of joint contracture and delay of motor deterioration in ALS mice. Halofuginone could also reduce glial cell-induced neuroinflammation and neuronal apoptosis. These dual therapeutic effects on both the neuromuscular system and the CNS were observed from the beginning to the end stages of ALS; as a result, treatment with a TGF-β inhibitor from the early stage of disease delayed the time of symptom exacerbation in ALS mice, which led to prolonged survival., (© 2024 The Authors.

Aim: Yokukansan is one of the most frequently used herbal medicines that can improve the behavioral and psychological symptoms of dementia. In this exploratory study, we investigated whether yokukansan affects the steady-state blood concentrations of donepezil, risperidone, and the major metabolites of both drugs in a real-world clinical setting., Methods: A non-randomized, open-label, single-arm study examining drug-drug interactions was conducted. Fifteen dementia patients taking donepezil for at least 4 weeks and eight schizophrenia patients taking risperidone for at least 2 weeks were orally administered 2.5 g of yokukansan three times a day before or between meals, and blood samples were collected before and 8 weeks after starting co-treatment with yokukansan. Plasma concentrations of donepezil, risperidone, and each metabolite were measured using high-performance liquid chromatography-tandem mass spectrometry and compared before and after the 8-week administration of yokukansan., Results: The plasma concentrations of donepezil and its metabolites (6-O-desmethyl-donepezil, 5-O-desmethyl-donepezil, and donepezil-N-oxide), risperidone, and its metabolite paliperidone did not differ before and after the 8-week treatment with yokukansan., Conclusions: The findings of this study show that the concomitant use of yokukansan may have little clinical impact on the steady-state blood levels of donepezil and risperidone in patients with dementia or schizophrenia., (© 2024 The Author(s).

Purpose: To review all cases of Erdheim-Chester disease (ECD) with orbital involvement treated at Bascom Palmer Eye Institute in Miami, Florida from 2014 to 2022 and compare presentations, treatment modalities, and outcomes., Methods: A retrospective chart review of all patients diagnosed with ECD who presented to Bascom Palmer Eye Institute from 2014 to 2022 was performed. Data collected included demographics, pretreatment history and ophthalmic examination, pathology report, treatment, subsequent examination, and relevant laboratory results. Histopathology, treatments, and outcomes were reviewed and compared between patients., Results: Four cases were included. Primary treatments included vemurafenib (n = 2), cobimetinib (n = 1), and prednisone (n = 1). All patients demonstrated improvement of ophthalmic symptoms. Vemurafenib was the only medical treatment that was tolerated well and resulted in significant improvement in proptosis despite some reported dry eye; all other medications were discontinued due to intolerable side effects., Conclusions: BRAF inhibitors such as vemurafenib have been used as novel therapy in the treatment of ECD. Vemurafenib demonstrated its utility in reducing proptosis in ECD patients at one ophthalmic institution. Vemurafenib may be a favorable treatment option for BRAF -positive ECD patients presenting with orbital disease., Competing Interests: STW is a consultant for Lassen Therapeutics and Immunovant, an advisor for Horizon Therapeutics, and participates in funded research with Horizon Therapeutics, Immunovant, and Sling Therapeutics.

Based on phase III clinical studies, four multi-kinase inhibitors (MKI) are approved for the treatment of progressive radioiodine-refractory differentiated thyroid carcinoma (rrDTC) and medullary thyroid carcinoma (MTC) in Germany. Only recently, based on the randomized trial COSMIC-311, Cabozantinib has been approved as a second-line treatment option in advanced rrDTC. As first in-label selective RET-Inhibitor, Selpercatinib showed promising efficacy in advanced MTC (first line) with RET mutations and rrDTC (second line) with RET fusions along with fewer side effects. Changes and new approaches for the treatment of ATC have been summarised in the current ATA guidelines., Competing Interests: Tim Brandenburg erklärt finanzielle Verbindungen zu Eisai (Vortragshonorare & Advisory Boards, zu Lilly (Vortragshonorare, Advisory Boards & Consultancy sowie zu Bayer Pharma (Advisory Boards).

Alopecia areata totalis and universalis are disabling conditions and therapeutically challenging as they are refractory to conventional options. Tofacitinib is a Janus-kinase (JAK) inhibitor utilized to treat alopecia areata (AA) as an off-label drug. In India, FDA-approved JAK inhibitors such as baricitinib and ritlecitinib are not available. There are only a few case reports on tofacitinib in AA in the Indian population. We present the data of 9 pediatric cases of clinically and histologically proven alopecia areata totalis (AT) and alopecia universalis (AU), for whom oral tofacitinib was given after baseline investigations. The following parameters were analysed: Photographic image and severity of alopecia tool (SALT) score at baseline, 3 months and 6 months, and Children Dermatology Life Quality Index (cDLQI) at baseline and 6 months. The mean ± standard deviation ( M  ± SD) of the SALT score and cDLQI( M  ± SD) at baseline were 95 ± 5 and 17 ± 2. At weeks 4 and weeks 12, the SALT ( M  ± SD) score was 92.7 ± 6.1 and 34.35 ± 11.16, respectively. At weeks 24, the SALT ( M  ± SD) score and cDLQI ( M  ± SD) were 3.33 ± 5 and 6 ± 2. The final reduction in SALT score from the baseline was 100% in 6/9 cases (66.67%), 75% to 99% in 3/9 (22.23%), and 50 to 75% in 1/9 (11.12%). We also observed minimal adverse effects (one child developed herpes zoster) with tofacitinib. Our study demonstrates that oral tofacitinib represents a viable modality in managing difficult-to-treat pediatric AA, such as AT and AU, with a good safety profile., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Backgruound: Guidelines for switching to triple combination therapy directly after monotherapy failure are limited. This study investigated the efficacy, long-term sustainability, and safety of either mono or dual add-on therapy using alogliptin and pioglitazone for patients with type 2 diabetes mellitus (T2DM) who did not achieve their target glycemic range with metformin monotherapy., Methods: The Practical Evidence of Antidiabetic Combination Therapy in Korea (PEAK) was a multicenter, placebo-controlled, double-blind, randomized trial. A total of 214 participants were randomized to receive alogliptin+pioglitazone (Alo+Pio group, n=70), alogliptin (Alo group, n=75), or pioglitazone (Pio group, n=69). The primary outcome was the difference in glycosylated hemoglobin (HbA1c) levels between the three groups at baseline to 24 weeks. For durability, the achievement of HbA1c levels <7% and <6.5% was compared in each group. The number of adverse events was investigated for safety., Results: After 24 weeks of treatment, the change of HbA1c in the Alo+Pio, Alo, and Pio groups were -1.38%±0.08%, -1.03%±0.08%, and -0.84%±0.08%, respectively. The Alo+Pio group had significantly lower HbA1c levels than the other groups (P=0.0063, P<0.0001) and had a higher proportion of patients with target HbA1c achievement. In addition, insulin sensitivity and β-cell function, lipid profiles, and other metabolic indicators were also improved. There were no significant safety issues in patients treated with triple combination therapy., Conclusion: Early combination triple therapy showed better efficacy and durability than the single add-on (dual) therapy. Therefore, combination therapy with metformin, alogliptin, and pioglitazone is a valuable early treatment option for T2DM poorly controlled with metformin monotherapy.

Objectives: To describe use and treatment persistence for Janus kinase inhibitors (JAKi) in rheumatoid arthritis (RA) by line of therapy, and the mechanism of action for the drug switched to after JAKi discontinuation., Methods: This was a retrospective, observational analysis using the OPAL dataset, a large collection of deidentified electronic medical records from 112 rheumatologists around Australia. Adult patients with RA were included if they initiated tofacitinib (TOF), baricitinib (BARI) or upadacitinib (UPA) between 1 October 2015 and 30 September 2021. Data were summarised using descriptive statistics. Kaplan-Meier survival was used to analyse treatment persistence., Results: 5,900 patients initiated JAKi within the study window (TOF n=3,662, BARI n=1,875, UPA n=1,814). Median persistence was similar across JAKi within each line of therapy where there was sufficient follow-up, and almost 3 years for first-line: 34.9 months (95% CI 30.8, 40.7; n=1,408) for TOF, 33.6 months (95% CI 25.7, not reached; n=545) for BARI. While JAKi to JAKi switching occurred across all lines of therapy, switches to a tumour necrosis factor inhibitor (TNFi) were more frequent after first- or second-line JAKi. JAKi monotherapy use at baseline increased with line of therapy, and was highest at follow-up after switching to another JAKi. 'Lack of efficacy' was the most common reason for discontinuing JAKi., Conclusions: In this large analysis of Australian real-world practice separated by line of therapy, treatment persistence for JAKi was high overall subject to differential follow-up, but declined in later lines. JAKi to JAKi switching was observed across all lines of therapy.

As of now, there exists no established therapy for ELP. Retinoids, which are standard in treating cutaneous LP, do not exhibit positive effects in ELP. While topical glucocorticosteroids often yield favorable responses in esophageal inflammation, some cases prove recalcitrant or refractory. In such instances, various immunosuppressive therapies have been attempted with variable success.This report details a severe case of ELP that showed resistance to prednisolone, acitretin, alitretinoin, adalimumab, tacrolimus, hydroxychloroquine plus mycophenolate mofetil, and cyclophosphamide. The initiation of the JAK inhibitor tofacitinib induced an impressive clinical, endoscopic, and histological remission. This positive response to a JAK inhibitor is discussed in the context of our evolving understanding of the immune-mediated pathogenesis of this disease., Competing Interests: FS was funded by the Berta-Ottenstein-Programme for Advanced Clinician Scientists, Faculty of Medicine, University of Freiburg.

Objectives: We sought to quantify exposure to and financial impacts of poly (adenosine diphosphate ribose) polymerase inhibitor (PARPi) treatments for eventually withdrawn ovarian cancer indications., Methods: We identified in Optum's deidentified Clinformatics® Data Mart database 1695 patients with ovarian cancer diagnoses who received olaparib, rucaparib, or niraparib between January 2015 and September 2021. We describe PARPi use and out-of-pocket, total healthcare, and PARPi spending among patients with ovarian cancer with 3 or more previous lines of therapy., Results: Of the 1695 patients who received PARPi, 254 were estimated to have been heavily pretreated and exposed to eventually withdrawn indications. Cumulative total medical and pharmacy costs for these patients were $53 392 184; PARPi costs accounted for 34%. Median PARPi cost per patient was $43 347. Cumulative out-of-pocket costs totaled $533 281., Conclusions: Potential patient harm, including financial toxicity, might have been mitigated through more stringent drug approval requirements., Competing Interests: Author Disclosures Author disclosure forms can be accessed below in the Supplemental Material section., (Copyright © 2024.

Objective: This study evaluated the long-term safety and efficacy of niraparib in Japanese patients with platinum-sensitive recurrent ovarian cancer., Methods: This was a follow-up analysis of a phase 2, multicenter, open-label, single-arm study in Japanese women with platinum-sensitive, relapsed ovarian cancer. Participants received niraparib (starting dose 300 mg) once daily in continuous 28-day cycles. The primary endpoint was the incidence of Grade 3 or 4 thrombocytopenia-related events (defined as the overall incidence of the MedDRA Preferred Terms "thrombocytopenia" and "platelet count decreased") occurring in the 30 days after initial administration of niraparib, and secondary endpoints included evaluation of treatment-emergent adverse events and progression-free survival., Results: Nineteen patients (median age, 62 years; median body weight, 53.9 kg) were enrolled. As previously reported, the incidence of Grade 3 or 4 thrombocytopenia-related events during the first 30 days of treatment was 31.6%. At data cutoff, median (range) treatment exposure was 504.0 (56-1,054) days and mean ± standard deviation dose intensity was 154.4±77.5 mg/day. The most common treatment-emergent adverse events were nausea (n=14, 73.7%), decreased platelet count (n=12, 63.2%), decreased neutrophil count (n=11, 57.9%), anemia, vomiting, and decreased appetite (all n=9, 47.4%). One patient was diagnosed with treatment-related leukemia, which resulted in death. Median (95% confidence interval) progression-free survival was 18.0 (5.6-26.7) months., Conclusion: Overall, the safety profile of niraparib was considered manageable in this study population of Japanese patients with platinum-sensitive, relapsed ovarian cancer and was consistent with that observed in studies of non-Japanese patients., Trial Registration: ClinicalTrials.gov Identifier: NCT03759587., Competing Interests: Kosei Hasegawa declares the receipt of research grants from Daiichi Sankyo, Eisai, MSD, and Takeda Pharmaceuticals Company Ltd, honoraria from AstraZeneca, Chugai, Daiichi Sankyo, Eisai, Genmab, Kaken, Kyowa Kirin, MSD, Sanofi, and Takeda Pharmaceuticals Company Ltd, and travel expenses from Regeneron.

Lichen planus (LP), an idiopathic, multifaceted chronic inflammatory disease with a heterogeneous clinical presentation, affects approximately 0.5-1% of the population. The various clinical manifestations of LP fall into three broad categories, namely cutaneous, appendageal, and mucosal, with further subclassification depending on the morphology and distribution patterns of individual lesions. There is mounting evidence that LP has systemic associations, including autoimmune conditions, glucose intolerance, dyslipidemia, and cardiovascular disorders. Cutaneous hypertrophic and mucosal forms of LP are at a heightened risk for malignant transformation. Familiarity with these potential associations in conjunction with long-term follow-up and regular screening could lead to a timely diagnosis and management of concomitant conditions. In addition, the frequent quality of life (QoL) impairment in LP underscores the need for a comprehensive approach including psychological evaluation and support. Several treatment strategies have been attempted, though most of them have not been adopted in clinical practice because of suboptimal benefit-to-risk ratios or lack of evidence. More recent studies toward pathogenesis-driven treatments have identified Janus kinase inhibitors such as tofacitinib, phosphodiesterase-4 inhibitors such as apremilast, and biologics targeting the interleukin-23/interleukin-17 pathway as novel therapeutic options, resulting in a dramatic change of the treatment landscape of LP. This contemporary review focuses on the diagnosis and management of LP, and places emphasis on more recently described targeted treatment options., (© 2024.

The role of the inflammasomes in aging and progeroid syndromes remain understudied. Recently, MCC950, a NLRP3 inhibitor, was used in Zmpste24 -/- mice to ameliorate the phenotypes. However, the safety of MCC950 was questioned due to liver toxicity observed in humans. Nevertheless, inhibition of the inflammasomes would be a beneficial therapy for progeria. Here, we show that OLT1177 (dapansutrile), other NLRP3 inhibitor, improved cellular and animal phenotypes using progeroid fibroblasts and a Lmna G609G/G609G mouse model. In both cases dapansutrile reduced progerin accumulation, NLRP3-inflammasome activation and secretory phenotype of senescence, extended the lifespan of progeroid animals, preserved bodyweight, and reduced kyphosis, inflammation, and senescence. Interestingly, dapansutrile further improved the effect of lonafarnib, the only FDA-approved drug for the progeria. The combination of both drugs reduced the inflammation and senescence, extended survival and ameliorated various progeroid defects both in vitro and in vivo, compared with treatment using lonafarnib alone. These findings and the safety of dapansutrile demonstrated in several clinical trials proposes it as a possible co-adjuvant treatment with lonafarnid in HGPS., (© 2024 The Author(s).

Objectives: To explore the effectiveness of tofacitinib for immunoglobulin G4-related disease (IgG4-RD) and idiopathic retroperitoneal fibrosis (IRF), and investigate the expression of JAKs in the lesion of these diseases., Methods: Clinical data of patients with IgG4-RD or IRF who were administered with tofacitinib monotherapy were collected. IgG4-RD responder index (IgG4-RD RI) was assessed. The expression of JAK1, JAK2, JAK3, and TYK2 were analysed with immunohistochemistry staining in three salivary glands specimens of IgG4-RD and one retroperitoneal tissue of IRF., Results: Two patients with IRF and two patients with IgG4-RD used tofacitinib monotherapy. Two patients with IRF achieved complete remission with diminished retroperitoneal mass and decreased CRP, as IgG4-RD RI decreased from 6 to 1 in both of them. One with IgG4-RD achieved complete remission with alleviated enlargement of pancreas and IgG4 level decreased from 13.7 g/L to 2.4 g/L, as IgG4-RD RI decreased from 12 to 1. One with IgG4-RD achieved partial response with IgG4 level decreased from 77.1g/L to 25.8g/L as IgG4-RD RI from 18 to 6. JAK1, JAK2, JAK3, and TYK2 expression were detected in biopsy tissues. The staining intensity of the JAK family on the lesion from one IRF patient was similar to those from IgG4-RD patients., Conclusions: Tofacitinib is a potentially effective treatment for IgG4-RD and IRF and it is reasonable to conduct clinical trial to validate its efficacy. The JAKs were expressed in the inflammatory lesions of IgG4-RD and IRF and they may share a common pathogenesis pathway that is independent of IgG4 production.

AdipoRon is an adiponectin receptor 1, 2 (ADIPOR1 and ADIPOR2) agonist with potential antifibrotic effects. Whether AdipoRon can mitigate joint stiffness in a rabbit model of arthrofibrosis is unknown. We examined the efficacy of intravenous (IV) AdipoRon at mitigating contracture in a rabbit model of knee arthrofibrosis. Fifty-six female New Zealand White rabbits were divided into three dosing groups: vehicle (dimethyl sulfoxide, DMSO), 2.5 mg/kg AdipoRon, and 5 mg/kg AdipoRon. AdipoRon, in DMSO, was administered IV preoperatively and for 5 days postoperatively (30 rabbits, Aim 1). AdipoRon was again dosed similarly after Kirschner wire (K-wire) removal at 8 weeks (26 rabbits; Aim 2). The primary outcome of joint passive extension angle (PEA,°) was measured at 8, 10, 12, 16, and 24 weeks following index surgery. At 24 weeks, rabbits were euthanized and limbs were harvested to measure posterior capsular stiffness (N cm/°). In Aim 1, the 5 mg/kg treated rabbits had a significant increase in PEA when compared to controls at 16-week (p < 0.05). In Aim 2, the 5 mg/kg treated rabbits had a significant increase in PEA when compared to controls at 10-week (p < 0.05). In both aims, no significant differences were observed at later time points. Capsular stiffness was no different in any group. We are the first to report the efficacy of IV AdipoRon in a rabbit model of arthrofibrosis. We identified a significant dose-dependent decrease in joint PEA at early time points; however, no differences were observed between groups at later time points. Clinical Significance: The present investigation provided the first assessment of AdipoRon's efficacy in mitigating knee stiffness in the current gold standard rabbit model of arthrofibrosis. Results of this investigation provided further evidence as to the potential role of AdipoRon as a preventative for arthrofibrosis in large mammals., (© 2024 Orthopaedic Research Society.)

Obesity is associated with metabolic inflammation, which can contribute to insulin resistance, higher blood glucose, and higher insulin indicative of prediabetes progression. The nucleotide-binding oligomerization domain-like receptor family pyrin domain containing 3 (NLRP3) inflammasome is a metabolic danger sensor implicated in metabolic inflammation. Many features of metabolic disease can activate the NLRP3 inflammasome; however, it is not yet clear which upstream triggers to target, and there are no clinically approved NLRP3 inflammasome inhibitors for metabolic disease. Bruton's tyrosine kinase (BTK) mediates activation of the NLRP3 inflammasome. Ibrutinib is the most-studied pharmacological inhibitor of BTK, and it can improve blood glucose control in obese mice. However, inhibitors of tyrosine kinases are permissive, and it is unknown if BTK inhibitors require BTK to alter endocrine control of metabolism or metabolic inflammation. We tested whether ibrutinib and acalabrutinib, a new generation BTK inhibitor with higher selectivity, require BTK to inhibit the NLRP3 inflammasome, metabolic inflammation, and blood glucose in obese mice. Chronic ibrutinib administration lowered fasting blood glucose and improved glycemia, whereas acalabrutinib increased fasting insulin levels and increased markers of insulin resistance in high-fat diet-fed CBA/J mice with intact Btk . These metabolic effects of BTK inhibitors were absent in CBA/CaHN-Btk xid /J mice with mutant Btk . However, ibrutinib and acalabrutinib reduced NF-κB activity, proinflammatory gene expression, and NLRP3 inflammasome activation in macrophages with and without functional BTK. These data highlight that the BTK inhibitors can have divergent effects on metabolism and separate effects on metabolic inflammation that can occur independently of actions on BTK. NEW & NOTEWORTHY Bruton's tyrosine kinase (BTK) is involved in immune function. It was thought that BTK inhibitors improve characteristics of obesity-related metabolic disease by lowering metabolic inflammation. However, tyrosine kinase inhibitors are permissive, and it was not known if different BTK inhibitors alter host metabolism or immunity through actions on BTK. We found that two BTK inhibitors had divergent effects on blood glucose and insulin via BTK, but inhibition of metabolic inflammation occurred independently of BTK in obese mice.

Background: Alopecia areata (AA) is an autoimmune hair loss disorder characterised by collapse of hair follicle immune privilege and mediated by autoreactive CD8+ T lymphocytes and natural killer cells. Treatment is often unsatisfactory. The Janus kinase-signal transducer and activator of transcription (JAK-STAT) pathway is implicated in the pathogenesis of AA and Janus Kinase inhibitor (JAKi) medications are promising emerging treatments for AA., Objectives: We evaluated the safety and effectiveness of tofacitinib in a real-world setting over 18 months of treatment., Methods: A retrospective cohort study of all patients with scalp AA commenced on tofacitinib between 1 November 2016 and 31 May 2019. The primary endpoint was the percent change in Severity of Alopecia Tool (SALT) score at 18 months., Results: Two hundred and two patients were included. After 18 months of treatment, 55.9%, 42.6% and 29.2% achieved 50%, 75% and 90% reductions in their SALT scores respectively. Increased duration of AA was a negative predictor of hair regrowth. Males and patients with baseline SALT ≥90 were slower to respond to treatment in the first 12 months. One hundred and twenty-four patients and 168 patients received concomitant systemic corticosteroids or low-dose oral minoxidil during tofacitinib therapy respectively. There were no serious adverse events., Conclusion: Tofacitinib was a safe and effective treatment for patients with moderate-to-severe AA. Further randomised controlled studies are needed to establish the optimal treatment regimen., (© 2024 Australasian College of Dermatologists.)

Objective: To better understand the pathogenesis of juvenile dermatomyositis (JDM), we examined the effect of the cytokines type I interferons (IFN I) and JAK inhibitor drugs (JAKi) on gene expression in bioengineered pediatric skeletal muscle., Methods: Myoblasts from three healthy pediatric donors were used to create three-dimensional skeletal muscle units termed myobundles. Myobundles were treated with IFN I, either IFNα or IFNβ. A subset of IFNβ-exposed myobundles was treated with JAKi tofacitinib or baricitinib. RNA sequencing analysis was performed on all myobundles., Results: Seventy-six myobundles were analysed. Principal component analysis showed donor-specific clusters of gene expression across IFNα and IFNβ-exposed myobundles in a dose-dependent manner. Both cytokines upregulated interferon response and proinflammatory genes; however, IFNβ led to more significant upregulation. Key downregulated pathways involved oxidative phosphorylation, fatty acid metabolism and myogenesis genes. Addition of tofacitinib or baricitinib moderated the gene expression induced by IFNβ, with partial reversal of upregulated inflammatory and downregulated myogenesis pathways. Baricitinib altered genetic profiles more than tofacitinib., Conclusion: IFNβ leads to more pro-inflammatory gene upregulation than IFNα, correlating to greater decrease in contractile protein gene expression and reduced contractile force. JAK inhibitors, baricitinib more so than tofacitinib, partially reverse IFN I-induced genetic changes. Increased IFN I exposure in healthy bioengineered skeletal muscle leads to IFN-inducible gene expression, inflammatory pathway enrichment, and myogenesis gene downregulation, consistent with what is observed in JDM., (© The Author(s) 2024.

A 67-year-old man had taken the janus kinase (JAK) inhibitor, tofacitinib, for ulcerative colitis. He was referred to our department for a refractory ulcer on his lower leg. We suspected vasculitis and performed skin biopsy. Histopathological examination showed multinucleated giant cells in the epidermis and fibrinoid degeneration of small vessels in the upper dermis. Varicella zoster virus (VZV) DNA was detected by polymerase chain reaction and we diagnosed the patient with atypical vasculitis-like herpes zoster. The patient was treated with oral valacyclovir, but the rash persisted and took 2 months to heal. Immunostaining using anti-VZV antibody was positive mainly in epidermal keratinocytes, but was also observed to be positive in cells in the dermis. We further performed RNA in situ hybridization using a VZV ORF9 mRNA probe and clearly showed that the distribution of VZV mRNA extended into the dermis, including the dermal vessel walls and the eccrine sweat glands as well as the epidermis. The internal administration of JAK inhibitors may induce regional widespread VZV infection including vessels and involved in the formation of prolonged vasculitis-like manifestation. RNA in situ hybridization can be a potent tool for detecting the spread of VZV infection in the skin., (© 2024 Japanese Dermatological Association.)

There are aspects of Janus kinase (JAK) inhibitors, specifically tofacitinib, that distinguish them from other drugs used in the treatment of ulcerative colitis (UC), such as their oral administration, their short half-life and their lack of immunogenicity. With the available evidence, we can highlight tofacitinib's quick action and flexibility of use, and its efficacy in patients, irrespective of whether or not they have previously been exposed to TNF inhibitors (anti-TNF drugs) and other biologic agents. Moreover, their safety profile is known and manageable, with certain considerations and precautions being factored in before and during treatment. In this review, we have defined various scenarios pertaining to this drug, e.g. its use in the event of failure or intolerance to previous treatment with biologics, when a quick response is required or in patients with other concurrent immune-mediated diseases.

Objective: To compare the risk of gastrointestinal perforation (GIP), a rare but serious adverse event, in patients who a JAK inhibitor (JAKi; tofacitinib, baricitinib, upadacitinib, or filgotinib) versus adalimumab (tumor necrosis factor inhibitor) among a comprehensive real-world population of patients with rheumatic diseases., Methods: We conducted a nationwide population-based cohort study of the French national health data system, the exposed group that received a JAKi and the comparison group adalimumab. We included all individuals with a rheumatic disease who had their first dispensation of these treatments from July 2017 to December 2021. The primary endpoint was the occurrence of GIP (end of follow-up May 2022). Weighted hazard ratios (wHRs) were estimated with the inverse probability of treatment weighting method to account for confounding factors. Concomitant administration of systemic glucocorticoids, nonsteroidal anti-inflammatory drugs, and proton-pump inhibitors were time-varying variables., Results: The cohort included 39,758 patients: 12,335 and 27,423 in the groups that received a JAKi and adalimumab (mean age 58.2 and 47.3 years; female 76% and 58%; rheumatoid arthritis 85.3% and 27.3%, and psoriatic arthritis/axial spondyloarthritis 14.7% and 72.7%), respectively. During follow-up, 38 and 42 GIPs occurred in the groups that received a JAKi and adalimumab groups; incidence rates were 2.1 (95% confidence interval [CI] 1.5-2.8) and 1.1 (95% CI 0.8-1.5) per 1,000 person-years, respectively. Rates of GIP did not differ between the groups that received a JAKi and adalimumab: wHR 1.1 (95% CI 0.7-1.9; P = 0.65). Despite the lack of power in some subgroup analyses, results were consistent whatever the subgroup of a type of JAKi received or subgroup with a type of rheumatic disease., Conclusion: In this nationwide cohort study, the rates of GIPs did not differ between groups of patients who received JAKi and adalimumab treatment. These results need to be confirmed in other observational studies., (© 2024 American College of Rheumatology.)

Objective: Thalidomide is an effective medication for refractory mucocutaneous lesions of systemic lupus erythematosus (SLE) and can treat arthritis in some autoimmune diseases, but it has some adverse reactions. Recently, the effectiveness of tofacitinib in treating mucocutaneous lesions of SLE has been reported. We aimed to compare the efficacy and safety of tofacitinib with thalidomide in treating mucocutaneous and musculoskeletal lesions in patients with SLE., Methods: This study was a real-world cohort study based on the Chinese SLE Treatment and Research group (CSTAR) registry. SLE patients who manifested mucocutaneous and/or musculoskeletal symptoms and were prescribed tofacitinib or thalidomide were included. We retrospectively conducted comparisons between the tofacitinib and thalidomide groups regarding clinical improvements, SLE disease activity, serological indicators, glucocorticoid doses, and adverse events at the 1, 3, and 6-months time points., Results: At 3 and 6 months, the tofacitinib group exhibited a higher proportion of patients with improvement in mucocutaneous and musculoskeletal issues. Additionally, a greater percentage of patients in the tofacitinib group achieved remission or a low disease activity state (LLDAS) at these time points. No significant serological improvements were observed in either the tofacitinib or thalidomide groups. Fewer adverse events were observed in the tofacitinib group than in the thalidomide group., Conclusions: Tofacitinib might be superior to thalidomide in the improvement of mucocutaneous and musculoskeletal lesions in SLE, and had a good safety profile., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: Alopecia areata (AA) is a recurrent immune-mediated disorder causing hair loss without any scarring being present. It affects hairs on the head or other parts of the body and can occur at any age and in both genders. It seems that AA is associated with a higher rate of psychological disorders resulting from hair loss and the esthetic and social repercussions of it. Common treatments like corticosteroids do not work for every patient and recent treatment options focusing on the immunologic mechanisms like tofacitinib have shown some promising results., Methods: It's a retrospective study on patients with AA, AT, AU taking oral tofacitinib as a treatment for at least 6 months. Scalp hair loss was assessed before treatment and at each visit using the Severity of Alopecia Tool (SALT) score., Results: Of 97 cases, 69.1% demonstrated over 50% SALT score improvement, with 44.3% having 90% or more decrease in SALT score. Patients who suffered from patchy AA were more responsive compared to patients with AT and AU subtypes and had a greater percent change in SALT score. Tofacitinib was tolerated quite well and no significant adverse events were reported., Conclusions: Tofacitinib should be taken into consideration as an efficacious treatment option for patients with AA, AT and AU., (© 2024 The Authors.

Objectives: Standard criteria for measuring treatment efficacy in patients with rheumatoid arthritis (RA) include American College of Rheumatology (ACR) response rates, which require meeting a threshold of ≥20/50/70% improvement in several physician- and patient-reported measures. We aimed to evaluate the impact of csDMARDs, TNF inhibitors (TNFi), and tofacitinib (TOFA) on ACR components in real-life practice., Methods: Clinical data of RA patients with a CDAI >10 at the time they started a treatment were pooled from two registries: Ontario Best Practices Research Initiative (OBRI) and RHUMADATA. Endpoints included proportions of patients achieving: ACR20/50/70 responses, ≥20/50/70% improvements and mean percentage improvement in individual ACR components at Month 6. We also adjusted for potential confounders to compare impact of these medications on outcomes of interest., Results: A total of 669 patients were included (csDMARD, n=157, TNFi, n=252; TOFA, n=260). An overall higher proportion in all three-medication groups achieved ≥20/50/70% improvement in primary ACR components vs. secondary components. Among secondary components, ≥20/50/70% improvement rates were numerically highest for PhGA and lowest for HAQ-DI and pain. Among ACR20/50/70 responders for all medications, the mean percentage improvement was more than 80% for primary components, and ranged from 30% to 80% for secondary components. A significantly lower proportion of patients in TNFi group achieved to at least 50% improvement in pain compared to TOFA after adjusting., Conclusions: In this real-world practice, physician-reported measures contribute slightly more to overall ACR20/50/70 responses. Pain was the most important factor in achieving an ACR50 TOFA users, possibly reflecting the different effects of JAKi on pain.

This study aims to test the hypothesis that disease duration may affect the response to generic tofacitinib (TOF) and investigate the influence of concomitant medications with TOF on elderly rheumatoid arthritis (RA). This study retrospectively collected 76 elderly patients (age > 60) treated with TOF from 2019 to 2023 and grouped them according to age of disease onset. Data were collected from baseline to the last follow-up visit within 24 months. The demographic characteristics and follow-up results were compared. TOF retention and the effect of concomitant drugs (methotrexate, MTX, prednisone) were analyzed using Kaplan-Meier plots and COX regression analysis. Canonical correlation analysis (CCA) was used to explore the correlation among demographic characteristics, medication regimen, and improved clinical outcomes. There was no significant difference in the proportion of patients achieving low disease activity (LDA) between different disease duration groups. Patients in the group of MTX had a shorter time of using TOF in follow-up (log-rank p = 0.041). Prednisone dosage at baseline had a predictive value for functionally disabled situation. We found significant associations between discontinuation of TOF in the last follow-up and getting LDA. A total result of CCA yielded a significant positive correlation with set 1 (demographic characteristics and medication regimen) and set 2 (improved clinical outcomes) (canonical coefficient = 0.887, p < 0.001). Disease duration may not affect response to generic TOF and medication regimen was the factor related to efficacy of generic TOF in elderly RA in the real world. Demographic characteristics and medication regimen were correlated positively with improved clinical outcomes. Key Points • There is scarce data from the western area of China regarding the use of tofacitinib in elderly rheumatoid arthritis patients, despite widespread use. • In this retrospective analysis of 76 elderly patients at a single center, we found disease duration may not affect response to generic TOF. • Concomitant MTX might contribute to better control of the disease activity. • Concomitant prednisone dosage at baseline was the independent risk factor for functionally disabled situation., (© 2024.

Purpose: To explore safety and tolerability parameters for the niraparib individualized starting dose (ISD) in patients with newly diagnosed advanced ovarian cancer that responded to platinum-based chemotherapy who participated in the phase 3 PRIMA/ENGOT-OV26/GOG-3012 trial (NCT02655016)., Methods: The PRIMA protocol was amended so newly enrolled patients received an ISD based on baseline body weight/platelet count. In this ad hoc analysis, the timing, duration, and resolution of the first occurrence of common any-grade hematologic (thrombocytopenia, anemia, neutropenia) and nonhematologic (nausea, asthenia/fatigue, constipation, insomnia, hypertension) treatment-emergent adverse events (TEAEs) were evaluated by treatment arm in the ISD safety population (data cutoff, November 17, 2021; median follow-up, 3.5 years)., Results: Of 733 randomized patients, 255 were enrolled after the ISD protocol amendment and received ≥ 1 dose of study treatment (niraparib, 169; placebo, 86). In the niraparib arm, median times to first events were 22.0-35.0 days for hematologic TEAEs and 7.0-56.0 days for nonhematologic TEAEs. First events resolved in ≥ 89.8% of patients for hematologic TEAEs; for nonhematologic TEAEs, resolution rates ranged from 55.3% (insomnia) to 86.0% (nausea). Median durations of first hematologic TEAEs were ≤ 16.0 days, but for first nonhematologic TEAEs ranged from 18.0 days (nausea) to 134.0 days (insomnia)., Conclusion: The niraparib ISD was generally well tolerated and TEAEs were manageable. Common hematologic and nonhematologic TEAEs occurred early and first events of hematologic TEAEs had a short duration (≈ 2 weeks) and a high resolution rate. These findings support close monitoring immediately following niraparib initiation and may help inform patient expectations for niraparib safety., Competing Interests: Declaration of Competing Interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Dr Vulsteke reports medical writing support from GSK; consulting fees from Astellas, Atheneum Partners, Bristol Myers Squibb, GSK, Janssen-Cilag, Leo Pharma, Merck Sharp & Dohme, and Roche; advisory board fees from AstraZeneca, Bayer, GSK, Janssen-Cilag, Leo Pharma, Merck Sharp & Dohme; and travel support from Pfizer and Roche.
