Background and Aims: Anti-programmed death 1 (PD-1) monotherapy triggers various responses by each organ. In advanced hepatocellular carcinoma (HCC), while extrahepatic lesions demonstrate objective response rates (ORR) of 20%-40%, only 10% of intrahepatic lesions respond. Although first-line atezolizumab/bevacizumab has shown survival benefits in advanced HCC, organ-specific responses remain unexplored. Therefore, we aimed to assess organ-specific responses in patients with advanced HCC receiving atezolizumab/bevacizumab., Methods: This retrospective, multicenter, observational study included patients who received first-line atezolizumab/bevacizumab for advanced HCC. Patients with Child-Pugh class A, measurable tumour lesions and serial imaging available for response evaluation were eligible., Results: Between May 2020 and June 2021, 131 patients (median age: 62) from three cancer referral institutions were included. Ninety-one had hepatitis B (69.5%), 108 were at Barcelona clinic liver cancer stage C (82.4%), and 78 had extrahepatic metastasis (59.5%). After a median follow-up of 10.1 months, median progression-free survival was 6.8 months (95% confidence interval [CI], 4.6-9.2), median overall survival remained unreached (95% CI, range unavailable) and the ORR was 29.0%. Among 270 individual tumour lesions, the liver was the most commonly involved organ (n = 158). Atezolizumab/bevacizumab induced ORR of 27.8%, 42.2%, 29.1% and 21.0% for liver, lymph nodes, lungs and other sites, respectively. The organ-specific response rate for intrahepatic tumours decreased with increasing size (35.6%: <5 cm, 15.0%: ≥ 5 cm)., Conclusions: Unlike anti-PD-1 monotherapy, atezolizumab/bevacizumab demonstrated favourable responses in intrahepatic lesions, comparable to those in extrahepatic lesions, and may potentially overcome the immune-tolerant hepatic microenvironment in patients with advanced HCC., (© 2024 The Authors.

Background: In 2020, atezolizumab-bevacizumab became the new standard of care (SOC) for first-line unresectable hepatocellular carcinoma (HCC) patients, following a decade where sorafenib was the preferred first-line treatment. In the last few years, a number of novel systemic treatments with non-inferiority and superiority to sorafenib have been approved as first-line treatments., Objectives: The objective of this systematic literature review (SLR) and network meta-analysis (NMA) was to compare randomised controlled trial evidence for atezolizumab-bevacizumab with globally relevant pharmacological comparators for first-line treatment of patients with unresectable HCC., Methods: Randomised controlled trials investigating first-line treatment of HCC in adults with no prior systemic treatment were eligible for inclusion into the SLR and were retrieved from Embase, MEDLINE, and Evidence-Based Medicine (EBM) Reviews. Interventions of interest for the NMA included atezolizumab-bevacizumab, sorafenib, lenvatinib, durvalumab (including in combination with tremelimumab), cabozantinib (including in combination with atezolizumab), camrelizumab (including in combination with rivoceranib), pembrolizumab (including in combination with lenvatinib), and tislelizumab. Random effects NMA was conducted for survival endpoints within a Bayesian framework with an informative prior distribution for between-study heterogeneity. The hazard ratios for relative treatment effect were estimated with 95% credible intervals (CrIs)., Results: The SLR identified 49 studies, of which eight formed a connected evidence network permitting the indirect treatment comparison of atezolizumab-bevacizumab with comparators of interest. The indirect comparisons suggested an improved overall survival (OS) with atezolizumab-bevacizumab versus most comparators. All indirect treatment comparison results for atezolizumab-bevacizumab included the null value within the 95% CrI ( n = 1) for OS and progression-free survival (PFS)., Conclusions: The results of the NMA indicate atezolizumab-bevacizumab is associated with superior or comparable OS and PFS together with a manageable safety profile compared with globally relevant comparators in the unresected HCC indication. The findings support that atezolizumab-bevacizumab remains SOC for the management of first-line unresectable HCC patients., Competing Interests: Arndt Vogel had been directly paid honoraria and has been paid consulting or advisory roles for AstraZeneca, BeiGene, Boehringer Mannheim, BMS, BTG, EISAI, GSK, Incyte, Ipsen, MSD, Hoffmann-La Roche, Servier, Sirtex, and Taiho.

Introduction: Atezolizumab and bevacizumab (Ate/Bev) combination has become the new first-line systemic therapy for unresectable hepatocellular carcinoma (HCC). Although several studies reported thyroid dysfunction after treatment with immune checkpoint inhibitors, the clinical and immunological significance of thyroid dysfunction in patients treated with Ate/Bev has not been comprehensively addressed. We aimed to comprehensively evaluate the clinical and immunological implications of thyroid dysfunction in unresectable HCC patients treated with Ate/Bev., Methods: We enrolled 208 patients with unresectable HCC treated with Ate/Bev from three Korean cancer centers. Thyroid adverse events (AEs) were reviewed, and cytokines and T cells in the blood samples were analyzed at baseline. For external validation, we analyzed clinical outcomes according to thyroid AEs in patients treated with Ate/Bev in the IMbrave150 study., Results: Forty-one (19.7%) out of 208 patients experienced thyroid dysfunction (hypothyroidism [17.3%] and thyrotoxicosis [5.8%]) after Ate/Bev treatment. Median time to onset of hypothyroidism and thyrotoxicosis after Ate/Bev treatment was 3.5 and 1.3 months, respectively. Patients with thyroid AEs demonstrated significantly better progression-free survival, overall survival, and objective response rate than those without thyroid AEs. These findings were still consistent even after adjusting for confounding factors. Furthermore, favorable survival outcomes in patients with thyroid AEs were also validated in a cohort of IMbrave150 patients. While patients with thyrotoxicosis showed a significantly lower level of baseline IL-6, those with hypothyroidism did not show significant differences in circulating cytokine levels and CD8 + T-cell fractions., Conclusions: A fraction of patients with HCC treated with Ate/Bev experienced thyroid dysfunction, and the development of thyroid AEs was associated with favorable clinical outcomes., Competing Interests: Hong Jae Chon has a consulting or advisory role at Eisai, Roche, Bayer, ONO, MSD, BMS, Celgene, Sanofi, Servier, AstraZeneca, SillaJen, Menarini, and GreenCross Cell and has received research grants from Roche, Dong-A ST, and Boryung Pharmaceuticals.

Background & Aims: We elucidated the clinical and immunologic implications of serum IL-6 levels in patients with unresectable hepatocellular carcinoma (HCC) treated with atezolizumab and bevacizumab (Ate/Bev)., Methods: We prospectively enrolled 165 patients with unresectable HCC (discovery cohort: 84 patients from three centres; validation cohort: 81 patients from one centre). Baseline blood samples were analysed using a flow cytometric bead array. The tumour immune microenvironment was analysed using RNA sequencing., Results: In the discovery cohort, clinical benefit 6 months (CB 6m ) was defined as complete or partial response, or stable disease for ≥6 months. Among various blood-based biomarkers, serum IL-6 levels were significantly higher in participants without CB 6m than in those with CB 6m (mean 11.56 vs . 5.05 pg/ml, p  = 0.02). Using maximally selected rank statistics, the optimal cut-off value for high IL-6 was determined as 18.49 pg/ml, and 15.2% of participants were found to have high IL-6 levels at baseline. In both the discovery and validation cohorts, participants with high baseline IL-6 levels had a reduced response rate and worse progression-free and overall survival after Ate/Bev treatment compared with those with low baseline IL-6 levels. In multivariable Cox regression analysis, the clinical implications of high IL-6 levels persisted, even after adjusting for various confounding factors. Participants with high IL-6 levels showed reduced interferon-γ and tumour necrosis factor-α secretion from CD8 + T cells. Moreover, excess IL-6 suppressed cytokine production and proliferation of CD8 + T cells. Finally, participants with high IL-6 levels exhibited a non-T-cell-inflamed immunosuppressive tumour microenvironment., Conclusions: High baseline IL-6 levels can be associated with poor clinical outcomes and impaired T-cell function in patients with unresectable HCC after Ate/Bev treatment., Impact and Implications: Although patients with hepatocellular carcinoma who respond to treatment with atezolizumab and bevacizumab exhibit favourable clinical outcomes, a fraction of these still experience primary resistance. We found that high baseline serum levels of IL-6 correlate with poor clinical outcomes and impaired T-cell response in patients with hepatocellular carcinoma treated with atezolizumab and bevacizumab., Competing Interests: HJC has a consulting or advisory role at Eisai, Roche, Bayer, ONO, MSD, BMS, Celgene, Sanofi, Servier, AstraZeneca, Sillajen, Menarini, and GreenCross Cell, and has received research grants from Roche, Dong-A ST, and Boryung Pharmaceuticals.

Systemic inflammation is a key risk factor for hepatocellular carcinoma (HCC) progression and poor outcomes. Inflammatory markers such as the neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) may have prognostic value in HCC treated with standard of care atezolizumab plus bevacizumab (Atezo-Bev). We conducted a multicenter, international retrospective cohort study of patients with unresectable HCC treated with Atezo-Bev to assess the association of NLR and PLR with overall survival (OS), progression-free survival (PFS), and objective response rates. Patients with NLR ≥ 5 had a significantly shorter OS (9.38 vs. 16.79 months, p < 0.001) and PFS (4.90 vs. 7.58 months, p = 0.03) compared to patients with NLR < 5. NLR ≥ 5 was an independent prognosticator of worse OS (HR 2.01, 95% CI 1.22−3.56, p = 0.007) but not PFS. PLR ≥ 300 was also significantly associated with decreased OS (9.38 vs. 15.72 months, p = 0.007) and PFS (3.45 vs. 7.11 months, p = 0.04) compared to PLR < 300, but it was not an independent prognosticator of OS or PFS. NLR and PLR were not associated with objective response or disease control rates. NLR ≥ 5 independently prognosticated worse survival outcomes and is worthy of further study and validation.

Background: IMbrave150 has established the superiority of atezolizumab plus bevacizumab over sorafenib in patients with unresectable hepatocellular carcinoma (HCC)., Methods: We generated a prospectively maintained database including patients treated with atezolizumab plus bevacizumab for unresectable HCC across Europe, Asia and USA. Clinico-pathologic characteristics were assessed for their prognostic influence on overall survival (OS) and progression-free survival (PFS) in univariable and multivariate analyses. Overall response rate by RECIST v1.1 and treatment-related adverse events (TRAEs) per CTCAE v.5.0 were reported., Results: Out of 433 patients, 296 Child-Pugh A and ECOG performance status01 patients received atezolizumab plus bevacizumab in first line and were included. Patients were mostly male (82.7%), cirrhotic (75%) with history of viral hepatitis (65.9%). Overall, 68.9% had Barcelona Clinic Liver Cancer C-stage HCC with portal vein tumour thrombosis (PVTT, 35%) and extrahepatic spread (EHS, 51.7%). After a median follow-up of 10.0 months (95% confidence interval (CI): 9.4-10.4), median OS and PFS were 15.7 (95% CI: 14.5-NE) and 6.9 months (95% CI: 6.1-8.3), respectively. In the response-evaluable patients (n = 273), overall response rate was 30.8%. Overall, 221 patients (74.6%) developed TRAEs, with 70 (23.6%) reporting grade 3 or higher TRAEs; 25 (8.4%) patients had bleeding events. OS was independently associated with baseline Albumin-bilirubin (ALBI) grade and PVTT. Shorter PFS was associated with AFP≥ 400 ng/ml, worse ALBI and presence of EHS., Conclusion: This global observational study confirms the reproducible safety and efficacy of atezolizumab plus bevacizumab in routine clinical practice. Within Child-Pugh-A criteria, the presence of PVTT and higher ALBI grade identify patients with poorer survival., Competing Interests: Conflict of interest statement AD received educational support for congress attend-ance from Roche.

Background and Aims: Atezolizumab plus bevacizumab (AtezoBev) is the standard of care for first-line treatment of unresectable HCC. No evidence exists as to its use in routine clinical practice in patients with impaired liver function., Approach and Results: In 216 patients with HCC who were consecutively treated with AtezoBev across 11 tertiary centers, we retrospectively evaluated treatment-related adverse events (trAEs) graded (G) according to Common Terminology Criteria for Adverse Events v5.0, including in the analysis all patients treated according to label (n = 202, 94%). We also assessed overall survival (OS), progression-free survival (PFS), overall response (ORR), and disease control rates (DCR) defined by Response Evaluation Criteria in Solid Tumors v1.1. Disease was mostly secondary to viral hepatitis, namely hepatitis C (n = 72; 36%) and hepatitis B infection (n = 35, 17%). Liver function was graded as Child-Pugh (CP)-A in 154 patients (76%) and CP-B in 48 (24%). Any grade trAEs were reported by 143 patients (71%), of which 53 (26%) were G3 and 3 (2%) G4. Compared with CP-A, patients with CP-B showed comparable rates of trAEs. Presence and grade of varices at pretreatment esophagogastroduodenoscopy did not correlate with bleeding events. After a median follow-up of 9.0 months (95% CI, 7.8-10.1), median OS was 14.9 months (95% CI, 13.6-16.3), whereas median PFS was 6.8 months (95% CI, 5.2-8.5). ORR and DCR were respectively 25% and 73%, with no difference across CP classes., Conclusions: This study confirms reproducible safety and efficacy of AtezoBev in routine practice. Patients with CP-B reported similar tolerability compared with CP-A, warranting prospective evaluation of AtezoBev in this treatment-deprived population., (© 2022 The Authors.

Purpose: Atezolizumab + bevacizumab is the new standard of care for systemic treatment-naïve, unresectable hepatocellular carcinoma (HCC). This exploratory study investigated on-treatment alpha-fetoprotein (AFP) response as a potential surrogate biomarker of prognosis for the combination therapy., Experimental Design: Data from Group A of the phase Ib GO30140 study were used to identify the optimal time for AFP measurement and AFP cutoffs to differentiate patients by their best confirmed response per independent review facility-assessed RECIST (IRF-RECIST) version 1.1: responders from nonresponders and patients with disease control from primary progressors. We applied these cutoffs to independent data from the atezolizumab + bevacizumab arm of the phase III IMbrave150 trial to distinguish patients based on (i) overall survival (OS) and progression-free survival (PFS) per IRF-RECIST 1.1 and (ii) best confirmed response per IRF-RECIST 1.1., Results: We derived AFP cutoffs of ≥75% decrease and ≤10% increase from baseline at 6 weeks to identify responders and those who had disease control, respectively. These cutoffs had high sensitivity and specificity in GO30140. In IMbrave150 patients, sensitivity was 0.59 and specificity was 0.86 for the ≥75% decrease AFP cutoff; the sensitivity was 0.77 and specificity was 0.44 for the ≤10% increase AFP cutoff. Both AFP cutoffs were associated with longer OS and PFS, particularly in patients with hepatitis B virus etiology (HR < 0.5; P < 0.01)., Conclusions: AFP response at 6 weeks after initiating treatment is a potential surrogate biomarker of prognosis for patients with HCC receiving atezolizumab + bevacizumab.

Background: Most phase 3 clinical trials of systemic therapy for first-line unresectable hepatocellular carcinoma (HCC) have failed, with the exception of SHARP, REFLECT, and IMbrave150. We conducted indirect comparisons of therapies evaluated for first-line HCC treatment., Summary: We conducted a systematic review and meta-analysis of treatments for adults with locally advanced or metastatic unresectable HCC and no prior systemic treatment, including atezolizu-mab plus bevacizumab, sorafenib, lenvatinib, nivolumab, selective internal radiotherapy (SIRT), transarterial chemoembolization, and placebo or best supportive care. Randomized controlled trials published from January 1, 2007, to March 12, 2020, were retrieved from MEDLINE and Embase. Qualitative assessment of heterogeneity evaluated study designs, populations, and outcomes. Indirect comparisons used generalized linear models with random effects within a Bayesian framework and informative priors. We calculated relative efficacy estimates with 95% credible intervals (CrIs) and Bayesian posterior probability estimates of atezolizumab-bevacizumab being superior to other treatments. Nine clinical studies with a total of 3,897 participants were identified from 8,783 records and used to build the all-trials evidence network. Indirect comparisons suggested an improved overall survival (OS) with atezolizumab-bevacizumab versus lenvatinib (odds ratio, 0.63 [95% CrI 0.39-1.04]; with 97% Bayesian posterior probability of being superior), nivolumab (0.68 [95% CrI 0.41-1.14]; 94%), sorafenib (0.59 [95% CrI 0.39-0.87]; 99%), SIRT (0.51 [95% CrI 0.32-0.82]; 100%), or placebo/best supportive care (0.40 [95% CrI 0.25-0.64]; 100%)., Key Messages: Within the context of indirect comparisons, analyses of OS favored atezolizumab-bevacizumab versus other treatment options for patients with locally advanced or metastatic unresectable HCC., Competing Interests: A.V. received honoraria, consulting fees, and speaker bureau fees from AstraZeneca, Bayer, Bristol-Myers Squibb, BTG, Eisai, Lilly, Incyte, Ipsen, Janssen, Merck, MSD, Novartis, Pierre Fabre, Roche, Sanofi, and Servier.

Background: The observational study HerMES collected primary data on effectiveness and safety of trastuzumab in patients with human epidermal growth receptor 2 (HER2)-positive cancer of the stomach or gastroesophageal junction (GEJ) in routine clinical practice, exploring the treatment with trastuzumab, chemotherapy backbones used, and the HER2 testing in a real-world setting in Germany., Subjects, Materials, and Methods: This noninterventional study observed patients with histologically confirmed, HER2-positive metastatic adenocarcinoma of the stomach or GEJ, who were treated with trastuzumab according to the physicians' judgement and clinical practice. The observation phase per patient took as long as the duration of the trastuzumab therapy, but for a maximum of 12 months. A subsequent extended follow-up phase lasted until the patient's death or the end of the study, that is, 2 years from start of the follow-up phase of the last patient. All data were analyzed descriptively., Results: Between February 2010 and July 2016, 364 patients were observed at 171 sites throughout Germany. The median overall survival was 14.1 months and the median progression-free survival was 7.9 months. The overall response rate was 43%. Safety was in line with previous reports. This study observed a high diversity of chemotherapy regimens that were combined with trastuzumab. Post hoc subgroup analyses showed differences in outcomes according to the chemotherapy regimen used., Conclusion: Trastuzumab treatment in everyday practice as observed in HerMES confirmed the positive results of the pivotal study ToGA in an observational, real-world setting., Implications for Practice: Real-world data of trastuzumab treatment of patients with gastroesophageal or gastric metastatic adenocarcinoma confirmed the positive results of the pivotal clinical trial. The observed median overall survival was 14.1 months and the median progression-free survival was 7.9 months. Although recommendations concerning administration of trastuzumab were well implemented, a high diversity of chemotherapy regimens were combined with trastuzumab. Regimens other than the in-label regimens, especially oxaliplatin-based doublets or 5-fluorouracil, leucovorin, oxaliplatin, taxane triplets, were used in 29% of patients. Observation of a second, marginal HER2-positivity population confirmed the benefit of trastuzumab predominantly for well-confirmed human epidermal growth receptor 2 (HER2)-positive tumors and the requirement of reliable HER2 testing., (© 2020 The Authors.

Background: Bevacizumab (Avastin®), a recombinant humanized monoclonal antibody, in combination with platinum-doublet chemotherapy has become a routine treatment for advanced non-small-cell lung cancer (NSCLC). The post-authorization, non-interventional study 'AVAiLABLE' assessed the effectiveness and safety of bevacizumab combined with chemotherapy as first-line treatment., Methods: Nine hundred and eighty-seven adult patients (mean age 61.5 years, 59.8% male) with non-resectable advanced, metastatic or recurrent, predominantly non-squamous NSCLC were evaluated at 185 sites across Germany. 72.8% of the patients had stage IV disease at start of observation, 90.1% had histologically confirmed adenocarcinoma and 80.8% met the bevacizumab label 'NSCLC other than predominantly squamous cell histology'. According to bevacizumab label, chemotherapy plus bevacizumab was recommended, followed by bevacizumab maintenance therapy. Effectiveness endpoints included response rates and progression-free survival (PFS); safety endpoints comprised adverse drug reactions (ADRs). Patients were followed until progression or intolerable toxicity. Data were evaluated by descriptive statistical methods., Results: Median PFS was 7.4 months (95% CI: 7.1; 8.4), overall response rate (ORR) 45.6% and disease control rate (DCR) 75%. The majority of patients (72.7%) achieved partial response or stable disease. Complete response was reached by 2.3%. 33.6% of patients experienced an ADR of grade ≥ 3. Bevacizumab-related ADRs of grade ≥ 3 occurred in 5.7% of patients, with the highest incidence for leukopenia, neutropenia, and hypertension., Conclusions: Results of the non-interventional study 'AVAiLABLE' confirmed the effectiveness and safety of bevacizumab in combination with platinum-based chemotherapy as first-line treatment for advanced NSCLC in accordance with previous studies. No new safety signals were identified. Maintenance therapy with bevacizumab was well tolerated and safe even over extended periods (> 20 cycles)., Trial Registration: ClinicalTrials.gov Identifier: NCT02596958; registered on 4 November 2015.

Purpose: The controlled phase III trial SATURN demonstrated that maintenance therapy with erlotinib after the first-line platinum-based chemotherapy prolonged progression-free survival (PFS) and overall survival (OS) of non-small cell lung cancer (NSCLC) patients with advanced, non-progressive disease. We conducted the non-interventional study SATURN NIS to investigate the effectiveness and tolerability of erlotinib maintenance in daily clinical practice., Methods: This single-arm NIS screened 290 patients with locally advanced or metastatic NSCLC (stage IIIB or IV) and stable disease after standard platinum-based first-line chemotherapy in 95 institutions across Germany. Erlotinib was dosed and administered corresponding to the terms of the marketing authorization at the time of recruitment. The main effectiveness endpoint was subjects' OS at 1 year. Subgroup analyses of survival estimates of OS and PFS were performed., Results: 272 patients were eligible for analysis (median age 66 years, 37.1% females, 99.6% Caucasian, median ECOG performance status 1, 61.8% adenocarcinoma, 96.3% of patients with stable disease). Maintenance therapy with erlotinib resulted in median OS comparable to that of the SATURN phase III trial 10.4 months [95% CI: (8.8; 12.5) vs. 11.9 months]. The 1-year survival rate was 45.6% [95% CI: (37.5%; 53.6%)]. No new safety signals were observed. As expected, patients with epidermal growth factor receptor (EGFR) mutations derived a greater benefit concerning OS and PFS than EGFR-wild-type patients. Moreover, a significant association of OS and PFS and the smoking status was observed., Conclusions: The results of this non-interventional study support the current clinical practice of erlotinib switch maintenance in EGFR-mutation-positive patients.
