- Abstract
Background: The INBUILD trial investigated the efficacy and safety of nintedanib versus placebo in patients with progressive fibrosing interstitial lung diseases (ILDs) other than idiopathic pulmonary fibrosis (IPF). We aimed to establish the effects of nintedanib in subgroups based on ILD diagnosis. Methods: The INBUILD trial was a randomised, double-blind, placebo-controlled, parallel group trial done at 153 sites in 15 countries. Participants had an investigator-diagnosed fibrosing ILD other than IPF, with chest imaging features of fibrosis of more than 10% extent on high resolution CT (HRCT), forced vital capacity (FVC) of 45% or more predicted, and diffusing capacity of the lung for carbon monoxide (DLco) of at least 30% and less than 80% predicted. Participants fulfilled protocol-defined criteria for ILD progression in the 24 months before screening, despite management considered appropriate in clinical practice for the individual ILD. Participants were randomly assigned 1:1 by means of a pseudo-random number generator to receive nintedanib 150 mg twice daily or placebo for at least 52 weeks. Participants, investigators, and other personnel involved in the trial and analysis were masked to treatment assignment until after database lock. In this subgroup analysis, we assessed the rate of decline in FVC (mL/year) over 52 weeks in patients who received at least one dose of nintedanib or placebo in five prespecified subgroups based on the ILD diagnoses documented by the investigators: hypersensitivity pneumonitis, autoimmune ILDs, idiopathic non-specific interstitial pneumonia, unclassifiable idiopathic interstitial pneumonia, and other ILDs. The trial has been completed and is registered with ClinicalTrials.gov, number NCT02999178. Findings: Participants were recruited between Feb 23, 2017, and April 27, 2018. Of 663 participants who received at least one dose of nintedanib or placebo, 173 (26%) had chronic hypersensitivity pneumonitis, 170 (26%) an autoimmune IL

Background Pirfenidone is an oral antifibrotic agent that has been shown to reduce the decline in lung function in patients with idiopathic pulmonary fibrosis (IPF). We performed an integrated analysis of safety data from five clinical trials evaluating pirfenidone in patients with IPF. Methods All patients treated with pirfenidone in the three multinational Phase 3 studies (CAPACITY (studies 004 and 006), ASCEND (study 016)) and two ongoing open-label studies (study 002 and study 012 (RECAP)) were included in the analysis. Safety outcomes were assessed during the period from the first dose until 28 days after the last dose of study drug. Results A total of 1299 patients were included in the analysis. The cumulative total exposure to pirfenidone was 3160 person exposure years (PEY). The median duration of exposure was 1.7 years (range 1 week to 9.9 years), and the mean (±SD) daily dose was 2053.8 (±484.9) mg. Gastrointestinal events (nausea (37.6%), diarrhoea (28.1%), dyspepsia (18.4%), vomiting (15.9%)) and rash (25.0%) were the most common adverse events; these were generally mild to moderate in severity and without significant clinical consequence. Elevations in alanine aminotransferase or aspartate aminotransferase greater than three times the upper limit of normal occurred in 40/1299 (3.1%) patients (adjusted incidence, 2.3 per 100 PEY). Elevations were generally transient and reversible with dose modification or discontinuation. Conclusions A comprehensive analysis of safety outcomes in a large and well-defined cohort of 1299 patients with IPF who were followed prospectively for up to 9.9 years demonstrated that long-term treatment with pirfenidone is safe and generally well tolerated. Trial registration numbers NCT00287716, NCT00287729, NCT00662038, NCT01366209.

Interstitial lung diseases (ILD), including those related to connective tissue disease (CTD), and idiopathic pulmonary fibrosis (IPF) carry high morbidity and mortality. Great efforts are under way to develop and investigate meaningful treatments in the context of clinical trials. However, efforts have been challenged by a lack of validated outcome measures and by inconsistent use of measures in clinical trials. Lack of consensus has fragmented effective use of strategies in CTD-ILD and IPF, with a history of resultant difficulties in obtaining agency approval of treatment interventions. Until recently, the patient perspective to determine domains and outcome measures in CTD-ILD and IPF had never been applied. Efforts described here demonstrate unequivocally the value and influence of patient involvement on core set development. Regarding CTD-ILD, this is the first OMERACT working group to directly address a manifestation/comorbidity of a rheumatic disease (ILD) as well as a disease not considered rheumatic (IPF). The OMERACT 11 proceedings of the CTD-ILD Working Group describe the forward and lateral process to include both the medical and patient perspectives in the urgently needed identification of a core set of preliminary domains and outcome measures in CTD-ILD and IPF.

Rationale: Clinical trial design in interstitial lung diseases (ILDs) has been hampered by lack of consensus on appropriate outcome measures for reliably assessing treatment response. In the setting of connective tissue diseases (CTDs), some measures of ILD disease activity and severity may be confounded by non-pulmonary comorbidities. Methods: The Connective Tissue Disease associated Interstitial Lung Disease (CTD-ILD) working group of Outcome Measures in Rheumatology-a non-profit international organisation dedicated to consensus methodology in identification of outcome measures-conducted a series of investigations which included a Delphi process including >248 ILD medical experts as well as patient focus groups culminating in a nominal group panel of ILD experts and patients. The goal was to define and develop a consensus on the status of outcome measure candidates for use in randomised controlled trials in CTD-ILD and idiopathic pulmonary fibrosis (IPF). Results: A core set comprising specific measures in the domains of lung physiology, lung imaging, survival, dyspnoea, cough and health-related quality of life is proposed as appropriate for consideration for use in a hypothetical 1-year multicentre clinical trial for either CTD-ILD or IPF. As many widely used instruments were found to lack full validation, an agenda for future research is proposed. Conclusion: Identification of consensus preliminary domains and instruments to measure them was attained and is a major advance anticipated to facilitate multicentre RCTs in the field.

BACKGROUND Idiopathic pulmonary fibrosis (IPF) is characterized by formation and proliferation of fibroblast foci. Endothelin-1 induces lung fibroblast proliferation and contractile activity via the endothelin A (ETA) receptor. OBJECTIVE To determine whether ambrisentan, an ETA receptor-selective antagonist, reduces the rate of IPF progression. DESIGN Randomized, double-blind, placebo-controlled, event-driven trial. (ClinicalTrials.gov: NCT00768300). SETTING Academic and private hospitals. PARTICIPANTS Patients with IPF aged 40 to 80 years with minimal or no honeycombing on high-resolution computed tomography scans. INTERVENTION Ambrisentan, 10 mg/d, or placebo. MEASUREMENTS Time to disease progression, defined as death, respiratory hospitalization, or a categorical decrease in lung function. RESULTS The study was terminated after enrollment of 492 patients (75% of intended enrollment; mean duration of exposure to study medication, 34.7 weeks) because an interim analysis indicated a low likelihood of showing efficacy for the end point by the scheduled end of the study. Ambrisentan-treated patients were more likely to meet the prespecified criteria for disease progression (90 [27.4%] vs. 28 [17.2%] patients; P = 0.010; hazard ratio, 1.74 [95% CI, 1.14 to 2.66]). Lung function decline was seen in 55 (16.7%) ambrisentan-treated patients and 19 (11.7%) placebo-treated patients (P = 0.109). Respiratory hospitalizations were seen in 44 (13.4%) and 9 (5.5%) patients in the ambrisentan and placebo groups, respectively (P = 0.007). Twenty-six (7.9%) patients who received ambrisentan and 6 (3.7%) who received placebo died (P = 0.100). Thirty-two (10%) ambrisentan-treated patients and 16 (10%) placebo-treated patients had pulmonary hypertension at baseline, and analysis stratified by the presence of pulmonary hypertension revealed similar results for the primary end point. LIMITATION The study was terminated early. CONCLUSION Ambrisentan was not effective in treating IPF and may be associated with an increased risk for disease progression and respiratory hospitalizations. PRIMARY FUNDING SOURCE Gilead Sciences.

Summary Background Idiopathic pulmonary fibrosis is a fatal disease for which no effective treatment exists. We assessed whether treatment with interferon gamma-1b improved survival compared with placebo in patients with idiopathic pulmonary fibrosis and mild-to-moderate impairment of pulmonary function. Methods 826 patients with idiopathic pulmonary fibrosis were enrolled from 81 centres in seven European countries, the USA, and Canada. Patients were randomly assigned (double-blind) in a 2:1 ratio to receive 200 μg interferon gamma-1b (n=551) or equivalent placebo (n=275) subcutaneously, three times per week. Eligible patients were aged 40–79 years, had been diagnosed in the past 48 months, had a forced vital capacity of 55–90% of the predicted value, and a haemoglobin-corrected carbon monoxide diffusing capacity of 35–90% of the predicted value. The primary endpoint was overall survival time from randomisation measured at the second interim analysis, when the proportion of deaths had reached 75% of those expected by the study conclusion. This study is registered with ClinicalTrials.gov, number NCT00075998. Findings At the second interim analysis, the hazard ratio for mortality in patients on interferon gamma-1b showed absence of minimum benefit compared with placebo (1·15, 95% CI 0·77–1·71, p=0·497), and indicated that the study should be stopped. After a median duration of 64 weeks (IQR 41–84) on treatment, 80 (15%) patients on interferon gamma-1b and 35 (13%) on placebo had died. Almost all patients reported at least one adverse event, and more patients on interferon gamma-1b group had constitutional signs and symptoms (influenza-like illness, fatigue, fever, and chills) than did those on placebo. Occurrence of serious adverse events (eg, pneumonia, respiratory failure) was similar for both treatment groups. Treatment adherence was good and few patients discontinued treatment prematurely in either group. Interpretation We cannot recommend treatment with interferon gamma-1b since the drug did not improve survival for patients with idiopathic pulmonary fibrosis, which refutes previous findings from subgroup analyses of survival in studies of patients with mild-to-moderate physiological impairment of pulmonary function.

- Abstract
Background: β-Thalassemia is an inherited blood disorder requiring lifetime management of anemia and its complications., Objective: This study aimed to determine the indirect costs and humanistic burden of β-thalassemia., Design: A systematic literature review was conducted., Data Sources and Methods: Searches were conducted in Embase, MEDLINE, MEDLINE In-Process, and EconLit (November 1, 2010, to November 25, 2020). Studies reporting indirect costs and health-related quality of life (HRQoL) for patients with β-thalassemia were eligible., Results: Seventy-five publications were included. Mean annual days lost due to transfusion-related absenteeism ranged from 15.6 to 35 days. Patients spent a mean of 592 min (standard deviation (SD): 349) daily on disease management on transfusion days and 91 min (SD: 221) daily on non-transfusion days. Patients with non-transfusion-dependent β-thalassemia (NTDT) showed worse HRQoL versus those with transfusion-dependent β-thalassemia (TDT) on the 36-item Short Form Health Survey (75.8 vs 66.5; p = 0.021). Caregivers of patients with TDT had more severe stress compared with patients (20.17 vs 18.95; p = 0.006), as measured by the standardized Cohen Perceived Stress Questionnaire., Conclusion: TDT is associated with substantial indirect costs and caregiver burden, and NTDT is associated with worse HRQoL. There is an unmet need for novel treatments in both TDT and NTDT that minimize patient and caregiver burden., Competing Interests: Yesim Aydinok has participated on advisory boards for Bristol Myers Squibb, CRISPR Therapeutics/Vertex, and Silence Therapeutics; has participated in speakers bureaus for Cerus, Chiesi, and Novartis; and has received research funding from Agios Pharmaceuticals, Bristol Myers Squibb, Imara, Ionis Pharmaceuticals, Novartis, and Resonance Health.

- Abstract
Challenges for the effective management of interstitial lung diseases (ILDs) include difficulties with the early detection of disease, accurate prognostication with baseline data, and accurate and precise response to therapy. The purpose of this Review is to describe the clinical and research gaps in the diagnosis and prognosis of ILD, and how machine learning can be applied to image biomarker research to close these gaps. Machine-learning algorithms can identify ILD in at-risk populations, predict the extent of lung fibrosis, correlate radiological abnormalities with lung function decline, and be used as endpoints in treatment trials, exemplifying how this technology can be used in care for people with ILD. Advances in image processing and analysis provide further opportunities to use machine learning that incorporates deep-learning-based image analysis and radiomics. Collaboration and consistency are required to develop optimal algorithms, and candidate radiological biomarkers should be validated against appropriate predictors of disease outcomes., Competing Interests: Declaration of interests SMH reports grants from Boehringer Ingelheim and NHLBI; service contracts from Calyx outside the present work; the US patent 10,706,533 Systems and Methods for Automatic Detection and Quantification of Pathology Using Dynamic Feature Classification (assigned to National Jewish Health and not licensed); grants and consulting fees from Veracyte; consulting fees from Lyra Therapeutics and IMIDEX; and payment or honorarium for attending the 2021 World Association of Sarcoidosis and Other Granulomatous Disease Conference.

- Abstract
Background: Migraine is one of the leading causes of disability worldwide. Erenumab is a fully human monoclonal antibody that targets the calcitonin gene-related peptide (CGRP) receptor. This study aimed to evaluate real-world evidence on the impact of erenumab on acute medication usage and health care resource utilization (HCRU) among migraine patients., Methods: This retrospective effectiveness study utilized the US Optum's de-identified Clinformatics® Data Mart database to identify migraine patients initiating erenumab between May 1, 2018 and September 30, 2019. Patients had to be at least 18 years old, with a minimum of three doses for erenumab in the 6-month post-index period and continuous medical/pharmacy coverage in the 12-month pre- and 6-month post-index period. The date of the first claim for erenumab served as the index date. Use of acute medications overall and at different drug class level, and HCRU were compared during the 6-month pre- vs. post-index period. Impact of erenumab on a composite endpoint of three possible events: 1) outpatient visit with a diagnosis of migraine and an associated acute medication claim within 7 days of the visit, 2) hospital admission with a primary diagnosis for migraine, or 3) emergency room visit with a primary diagnosis for migraine (any events that occurred ≤3 days apart were counted only once) was also evaluated., Results: The analysis included 3171 identified patients. At 6 months, following initiation of erenumab, acute medication use including the number of types of acute medication, number of claims of each medication and % of patients who received acute medication, and HCRU were significantly decreased. For the composite outcome, the mean number of events decreased from 1.03 to 0.77 (rate ratio: 0.75; 95% CI: 0.71 to 0.79; P < 0.0001). A decrease in the proportion of patients with any of the three events was also observed (52.7% vs. 39.5%, P < 0.0001)., Conclusion: In this retrospective analysis, erenumab was associated with significantly reduced acute medication use and HCRU in a real-world setting, hence significantly reducing the burden of the disease. A composite endpoint could be used as a proxy to evaluate the burden of migraine attacks; however, further research is needed.

- Abstract
The coronavirus SARS-CoV-2 is cause of a global pandemic of a pneumonia-like disease termed Coronavirus Disease 2019 (COVID-19). COVID-19 presents a high mortality rate, estimated at 3.4%. More than 1 out of 4 hospitalized COVID-19 patients require admission to an Intensive Care Unit (ICU) for respiratory support, and a large proportion of these ICU-COVID-19 patients, between 17% and 46%, have died. In these patients COVID-19 infection causes an inflammatory response in the lungs that can progress to inflammation with cytokine storm, Acute Lung Injury (ALI), Acute Respiratory Distress Syndrome (ARDS), thromboembolic events, disseminated intravascular coagulation, organ failure, and death. Mesenchymal Stem Cells (MSCs) are potent immunomodulatory cells that recognize sites of injury, limit effector T cell reactions, and positively modulate regulatory cell populations. MSCs also stimulate local tissue regeneration via paracrine effects inducing angiogenic, anti-fibrotic and remodeling responses. MSCs can be derived in large number from the Umbilical Cord (UC). UC-MSCs, utilized in the allogeneic setting, have demonstrated safety and efficacy in clinical trials for a number of disease conditions including inflammatory and immune-based diseases. UC-MSCs have been shown to inhibit inflammation and fibrosis in the lungs and have been utilized to treat patients with severe COVID-19 in pilot, uncontrolled clinical trials, that reported promising results. UC-MSCs processed at our facility have been authorized by the FDA for clinical trials in patients with an Alzheimer's Disease, and in patients with Type 1 Diabetes (T1D). We hypothesize that UC-MSC will also exert beneficial therapeutic effects in COVID-19 patients with cytokine storm and ARDS. We propose an early phase controlled, randomized clinical trial in COVID-19 patients with ALI/ARDS. Subjects in the treatment group will be treated with two doses of UC-MSC (l00 × 10
6 cells). The first dose will be infused within 24 hours following study enrollment. A second dose will be administered 72 ± 6 hours after the first infusion. Subject in the control group will receive infusion of vehicle (DPBS supplemented with 1% HSA and 70 U/kg unfractionated Heparin, delivered IV) following the same timeline. Subjects will be evaluated daily during the first 6 days, then at 14, 28, 60, and 90 days following enrollment (see Schedule of Assessment for time window details). Safety will be determined by adverse events (AEs) and serious adverse events (SAEs) during the follow-up period. Efficacy will be defined by clinical outcomes, as well as a variety of pulmonary, biochemical and immunological tests. Success of the current study will provide a framework for larger controlled, randomized clinical trials and a means of accelerating a possible solution for this urgent but unmet medical need. The proposed early phase clinical trial will be performed at the University of Miami (UM), in the facilities of the Diabetes Research Institute (DRI), UHealth Intensive Care Unit (ICU) and the Clinical Translational Research Site (CTRS) at the University of Miami Miller School of Medicine and at the Jackson Memorial Hospital (JMH)., Competing Interests: Conflict of Interest All authors declare that there are no conflicts of interest regarding the publication of this manuscript.- Published

- Abstract
Unlabelled: Postmenopausal women are more susceptible to poor wound healing. This phenomenon can be reversed by estrogen replacement therapy in non-diabetic individuals. Postmenopausal women with type 2 diabetes are more susceptible to wound healing complications, potentially secondary to an estrogen deficiency. Few studies have examined the mechanism of action and effects of estrogens on diabetic wound healing in females. It appears that multiple factors influence delayed wound healing among individuals with diabetes including: an imbalance in cytokines, growth factors, extracellular matrix (ECM) turnover, and oxidant stress (OS). Estrogens have been shown to regulate the expression of genes important for extracellular matrix turnover, including collagen and matrix metalloproteinases (MMP)., Methods: For this reason, the effects of 17β-estradiol (E2) on MMP-2, MMP-13, and MMP-14 and estrogen receptor alpha and beta (ER-α and -β) expression in the wound tissue of estrogen-deficient female mice with established type 2 diabetes mellitus (C57BL/6J-m Leprdb/2+) were studied., Results: Topical E2 upregulates ERα in wound tissue thereby improving and accelerating diabetic wound healing in estrogen deficient mice., Conclusion: The mechanism appears to decrease MMP-2, MMP-13, and MMP-14 mediated tissue matrix destruction and increasing collagen content. .

- Abstract
We evaluated the contribution of spousal feedback to a parent education curriculum designed for parents of children with autism. A modified multiple baseline design across 3 husband-and-wife dyads was used to examine the effects of teaching parents to give each other feedback on their teaching performance. For 5 of 6 participants, improvement in teaching performance occurred following didactic presentations. However, additional improvement was observed for 5 participants when the spousal feedback component was implemented.

- Abstract
Objective: To determine the concentrations of immunoreactive (IR) endothelin-1 in human follicular fluid (FF) and whether IR-endothelin-1 levels are different in women with endometriosis-associated infertility., Design: Follicular fluid and plasma samples, obtained from women with and without endometriosis undergoing IVF-ET, were collected at the time of oocyte aspiration and analyzed for IR-endothelin-1 levels., Setting: Infertility clinic in an academic research environment., Results: Overall, 90% of FF samples and 60% of plasma samples contained IR-endothelin-1 detectable above the threshold of assay sensitivity. Immunoreactive endothelin-1 levels (mean +/- SEM) in FF samples from women with and without endometriosis-associated infertility were 74 +/- 12 and 37 +/- 6 pg/mL, respectively. There was no difference in IR-endothelin-1 levels in FF samples between controlled ovarian hyperstimulation cycles with or without leuprolide acetate. No significant differences were detected in plasma IR-endothelin-1 levels in women with endometriosis-associated infertility when compared with those without., Conclusions: These results demonstrate the presence of IR-endothelin-1 in human FF obtained at the time of oocyte aspiration for IVF-ET and higher levels of IR-endothelin-1 in FF of women with endometriosis-associated infertility.

- Abstract
The effect of reversible blood-brain barrier modification on the delivery of Adriamycin to the brain was studied in a rodent and canine model. Pharmacokinetic and physiological studies were done in these animals after a wide range of doses of Adriamycin (0.1 to 1.0 mg/kg) were administered into the carotid artery following osmotic barrier modification with mannitol. In the absence of barrier modification, no immunoreactive Adriamycin was detected in the cerebrum; whereas, following barrier modification, up to 4.5 micrograms of drug and/or metabolites per g of brain were found. Optimum tissue levels of Adriamycin and metabolites were achieved following barrier modification when the drug was administered by either bolus or slow continuous (15-min) infusion. Immunoreactive drug was identified in brain for up to 6 hr after administration. Significant functional neurotoxicity occurred at all dose levels, even at 0.1 mg/kg, a level at which Adriamycin concentration in the brain was below the level of detectability. Neuropathological examination revealed the presence of necrosis and hemorrhagic infarcts. Thus, these pharmacological and toxicity studies suggest that Adriamycin (or its metabolites) may produce significant clinical neurotoxicity when even small amounts penetrate the blood-brain barrier.

- Abstract
The conditioned medium (CM) from microvascular and macrovascular endothelial cell (EC) cultures was tested for constrictor activity. Sheep coronary artery rings, under 1 g tension, and sheep tracheal smooth muscle strips, under 2 g tension, were hung in organ baths containing Krebs-Henseleit solution (39 degrees C) and were equilibrated with 95% O2 and 5% CO2. Isometric force was measured in response to 80 mM KCl and constrictor responses to 100% CM were expressed as a percentage of maximum KCl response. Serum-free CM from confluent microvascular endothelial cells caused a sustained, slow-onset contraction of the coronary rings similar to that obtained with CM from macrovascular ECs. Indomethacin (5 microM) added to either the microvascular or macrovascular CM enhanced the constrictor responses by 1.6- and 1.8-fold, respectively, and the constrictor effects of both media were reduced by the calcium antagonist gallopamil (10 nM). CM from macrovascular EC caused a sustained contraction of tracheal strips similar to microvascular CM. In both cases, constriction was preceded by a brief relaxation as noted in vascular smooth muscle. Unconditioned medium had no constrictor activity on either vascular or airway smooth muscle. Microvascular-derived constrictor activity was heat stable. There was a slight loss of activity in the heat-treated CM from the macrovascular cells compared with control CM. Constrictor effects on tracheal smooth muscle were partially reversed by 1 microM gallopamil.
