Efficacy and safety of first-line avelumab in patients with advanced non-small cell lung cancer: results from a phase Ib cohort of the JAVELIN Solid Tumor study.

ABSTRACT: INTRODUCTION:Avelumab, an antiprogrammed death ligand-1 antibody, is approved as a monotherapy for treatment of metastatic Merkel cell carcinoma and advanced urothelial carcinoma, and in combination with axitinib for advanced renal cell carcinoma. We report the efficacy and safety of first-line avelumab in advanced non-small cell lung cancer (NSCLC). METHODS:In a phase I expansion cohort of the JAVELIN Solid Tumor trial, patients with treatment-naive, metastatic, or recurrent NSCLC received 10 mg/kg avelumab intravenously every 2 weeks. Endpoints included best overall response, duration of response (DOR), progression-free survival (PFS), overall survival (OS), and safety. RESULTS:Overall, 156 patients were enrolled and treated. Median duration of follow-up was 18.6 months (range, 15 to 23 months). The objective response rate was 19.9% (95% CI, 13.9 to 27.0), including complete response in 3 (1.9%) and partial response in 28 (17.9%). Median DOR was 12.0 months (95% CI, 6.9 to not estimable). Median PFS was 4.0 months (95% CI, 2.7 to 5.4) and the 6-month PFS rate was 38.5% (95% CI, 30.7 to 46.3). Median OS was 14.1 months (95% CI, 11.3 to 16.9) and the 12-month OS rate was 56.6% (95% CI, 48.2 to 64.1). Treatment-related adverse events (TRAEs) occurred in 107 patients (68.6%), including grade ?3 TRAEs in 19 (12.2%). Immune-related adverse events and infusion-related reactions occurred in 31 (19.9%) and 40 patients (25.6%), respectively. No treatment-related deaths occurred. CONCLUSION:Avelumab showed antitumor activity with a tolerable safety profile as a first-line treatment in patients with advanced NSCLC. These data support further investigation of avelumab in the phase III JAVELIN Lung 100 study. TRIAL REGISTRATION DETAILS:ClinicalTrials.gov NCT01772004; registered January 21, 2013.

Project description:ImportancePatients with malignant mesothelioma whose disease has progressed after platinum and pemetrexed treatment have limited options. Anti-programmed cell death 1 (PD-1) antibodies have antitumor activity in this disease, but little is known about the activity of anti-programmed cell death ligand 1 (PD-L1) antibodies in patients with mesothelioma.ObjectiveTo assess the efficacy and safety of avelumab in a cohort of patients with previously treated mesothelioma.Design, setting, and participantsPhase 1b open-label study (JAVELIN Solid Tumor) in patients with unresectable mesothelioma that progressed after platinum and pemetrexed treatment, enrolled at 25 sites in 3 countries between September 9, 2014, and July 22, 2015.InterventionsParticipants received avelumab, 10 mg/kg, every 2 weeks until disease progression, unacceptable toxic effects, or withdrawal from the study.Main outcomes and measuresPrespecified end points included confirmed best overall response based on Response Evaluation Criteria In Solid Tumors, version 1.1; duration of response; progression-free survival (PFS); overall survival (OS); PD-L1 expression-based analyses; and safety.ResultsOf 53 patients treated with avelumab, the median age was 67 (range, 32-84) years; 32 (60%) were male. As of December 31, 2016, median follow-up was 24.8 (range, 16.8-27.8) months. Twenty patients (38%) had 3 or more previous lines of therapy (median, 2; range, 1-8). The confirmed objective response rate (ORR) was 9% (5 patients; 95% CI, 3.1%-20.7%), with complete response in 1 patient and partial response in 4 patients. Responses were durable (median, 15.2 months; 95% CI, 11.1 to not estimable months) and occurred in patients with PD-L1-positive tumors (3 of 16; ORR, 19%; 95% CI, 4.0%-45.6%) and PD-L1-negative tumors (2 of 27; ORR, 7%; 95% CI, 0.9%-24.3%) based on a 5% or greater PD-L1 cutoff. Disease control rate was 58% (31 patients). Median PFS was 4.1 (95% CI, 1.4-6.2) months, and the 12-month PFS rate was 17.4% (95% CI, 7.7%-30.4%). Median OS was 10.7 (95% CI, 6.4-20.2) months, and the median 12-month OS rate was 43.8% (95% CI, 29.8%-57.0%). Five patients (9%) had a grade 3 or 4 treatment-related adverse event, and 3 (6%) had a grade 3 or 4 immune-related, treatment-related adverse event. There were no treatment-related deaths.Conclusions and relevanceAvelumab showed durable antitumor activity and disease control with an acceptable safety profile in a heavily pretreated cohort of patients with mesothelioma.Trial registrationClinicalTrials.gov identifier: NCT01772004.

Project description:BACKGROUND:Anti-programmed cell death ligand 1 (PD-L1)/programmed cell death 1 antibodies have shown clinical activity in platinum-treated metastatic urothelial carcinoma, resulting in regulatory approval of several agents, including avelumab (anti-PD-L1). We report ?2-year follow-up data for avelumab treatment and exploratory subgroup analyses in patients with urothelial carcinoma. METHODS:Patients with previously treated advanced/metastatic urothelial carcinoma, pooled from two cohorts of the phase Ib JAVELIN Solid Tumor trial, received avelumab 10?mg/kg every 2 weeks until disease progression, unacceptable toxicity or withdrawal. End points included best overall response and progression-free survival (PFS) per RECIST V.1.1, overall survival (OS) and safety. Post hoc analyses included objective response rates (ORRs) in subgroups defined by established high-risk/poor-prognosis characteristics and association between time to response and outcome. RESULTS:249 patients received avelumab; efficacy was assessed in 242 postplatinum patients. Median follow-up was 31.9 months (range 24-43), and median treatment duration was 2.8 months (range 0.5-42.8). The confirmed ORR was 16.5% (95% CI 12.1% to 21.8%; complete response in 4.1% and partial response in 12.4%). Median duration of response was 20.5 months (95%?CI 9.7 months to not estimable). Median PFS was 1.6 months (95%?CI 1.4 to 2.7 months) and the 12-month PFS rate was 16.8% (95% CI 11.9% to 22.4%). Median OS was 7.0 months (95%?CI 5.9 to 8.5 months) and the 24-month OS rate was 20.1% (95% CI 15.2% to 25.4%). In post hoc exploratory analyses, avelumab showed antitumor activity in high-risk subgroups, including elderly patients and those with renal insufficiency or upper tract disease; ORRs were numerically lower in patients with liver metastases or low albumin levels. Objective response achieved by 3 months versus later was associated with longer OS (median not reached (95%?CI 18.9 months to not estimable) vs 7.1 months (95%?CI 5.2 to 9.0 months)). Safety findings were consistent with previously reported 6-month analyses. CONCLUSIONS:After ?2 years of follow-up, avelumab showed prolonged efficacy and acceptable safety in patients with platinum-treated advanced/metastatic urothelial carcinoma, including high-risk subgroups. Survival appeared longer in patients who responded within 3 months. Long-term safety findings were consistent with earlier reports with avelumab treatment in this patient population.

Project description:BACKGROUND:We evaluated the antitumor activity and safety of avelumab, a human anti-PD-L1 IgG1 antibody, as first-line switch-maintenance (1?L-mn) or second-line (2?L) treatment in patients with advanced gastric/gastroesophageal cancer (GC/GEJC) previously treated with chemotherapy. METHODS:In a phase 1b expansion cohort, patients without (1?L-mn) or with (2?L) disease progression following first-line chemotherapy for advanced GC/GEJC received avelumab 10?mg/kg intravenously every 2?weeks. Endpoints included best overall response, progression-free survival (PFS), overall survival (OS), and safety. RESULTS:Overall, 150 patients were enrolled (1?L-mn, n?=?90; 2?L, n?=?60) and median follow-up in the 1?L-mn and 2?L subgroups was 36.0 and 33.7?months, respectively. The confirmed objective response rate was 6.7% in both subgroups (95% CI, 2.5-13.9% and 1.8-16.2%, respectively), including complete responses in 2.2% of the 1?L-mn subgroup (n?=?2). In the 1?L-mn and 2?L subgroups, median duration of response was 21.4?months (95% CI, 4.0-not estimable) and 3.5?months (95% CI, 2.8-8.3) and disease control rates were 56.7 and 28.3%, respectively. Median PFS in the 1?L-mn and 2?L subgroups was 2.8?months (95% CI, 2.3-4.1) and 1.4?months (95% CI, 1.3-1.5), with 6-month PFS rates of 23.0% (95% CI, 14.7-32.4%) and 7.9% (95% CI, 2.6-17.2%), and median OS was 11.1?months (95% CI, 8.9-13.7) and 6.6?months (95% CI, 5.4-9.4), respectively. In the 1?L-mn subgroup, median OS measured from start of 1?L chemotherapy was 18.7?months (95% CI, 15.4-20.6). Across both subgroups, 20.7% had an infusion-related reaction of any grade. Other common treatment-related adverse events (TRAEs) of any grade included fatigue (10.0%) and nausea (6.7%). Treatment-related serious adverse events occurred in 4.0% of patients. Overall, 8.7% had a grade??3 TRAE, including 1 treatment-related death. CONCLUSION:Avelumab showed clinical activity and an acceptable safety profile in patients with GC/GEJC.

Project description:ImportanceCurrent treatment options for progressive ovarian cancer provide limited benefit, particularly in patients whose disease has become resistant to platinum-based chemotherapy.ObjectiveTo assess the efficacy and safety of avelumab, an anti-programmed death-ligand 1 agent, in a cohort of patients with previously treated recurrent or refractory ovarian cancer.Design, setting, and participantsIn an expansion cohort of a phase 1b, open-label study (JAVELIN Solid Tumor), 125 patients with advanced ovarian cancer who had received chemotherapy including a platinum agent were enrolled between November 6, 2013, and August 27, 2015. Statistical analysis was performed from December 31, 2016, to October 9, 2018.InterventionPatients received avelumab, 10 mg/kg, every 2 weeks until disease progression, unacceptable toxic effects, or withdrawal from the study.Main outcomes and measuresPrespecified end points in this cohort included confirmed best overall response (per Response Evaluation Criteria In Solid Tumors, version 1.1), immune-related best overall response, duration of response, progression-free survival, overall survival, results of programmed death-ligand 1 expression-based analyses, and safety.ResultsA total of 125 women (median age, 62.0 years [range, 27-84 years]) who had received a median of 3 prior lines of treatment (range, 0-10) for advanced disease were enrolled in the study. Patients received avelumab for a median of 2.8 months (range, 0.5-27.4 months), with a median follow-up of 26.6 months (range, 16-38 months). A confirmed objective response occurred in 12 patients (9.6%; 95% CI, 5.1%-16.2%), including a complete response in 1 patient (0.8%) and a partial response in 11 patients (8.8%). The 1-year progression-free survival rate was 10.2% (95% CI, 5.4%-16.7%) and median overall survival was 11.2 months (95% CI, 8.7-15.4 months). Infusion-related reactions occurred in 25 patients (20.0%). Other frequent treatment-related adverse events (any grade event occurring in ≥10% of patients) were fatigue (17 [13.6%]), diarrhea (15 [12.0%]), and nausea (14 [11.2%]). Grade 3 or higher treatment-related adverse events occurred in 9 patients (7.2%), of which only the level of lipase increased (3 [2.4%]) occurred in more than 1 patient. Twenty-one patients (16.8%) had an immune-related adverse event of any grade. No treatment-related deaths occurred.Conclusions and relevanceAvelumab demonstrated antitumor activity and acceptable safety in heavily pretreated patients with recurrent or refractory ovarian cancer.Trial registrationClinicalTrials.gov identifier: NCT01772004.

Project description:BackgroundIn the phase III JAVELIN Renal 101 trial, first-line avelumab plus axitinib demonstrated a progression-free survival (PFS) and objective response rate (ORR) benefit versus sunitinib in patients with advanced renal cell carcinoma (aRCC). However, efficacy in elderly patients remains unclear. We report efficacy and safety by age group from the second interim analysis of overall survival (OS).Patients and methodsPFS and ORR as per blinded independent central review (RECIST 1.1), OS, and safety were assessed in patient groups aged <65, ≥65 to <75, and ≥75 years.ResultsIn the avelumab plus axitinib and sunitinib arms, 271/138/33 and 275/128/41 patients aged <65, ≥65 to <75, and ≥75 years, respectively, were randomized. At data cut-off (January 2019), median PFS [95% confidence interval (CI)] with avelumab plus axitinib versus sunitinib in these respective age groups was 11.6 (8.4-19.4) versus 6.9 (5.6-8.4) months [hazard ratio (HR), 0.63; 95% CI 0.501-0.786], 13.8 (11.1-18.0) versus 11.0 (7.8-16.6) months (HR, 0.88; 95% CI 0.627-1.231), and 13.8 [7.0-not estimable (NE)] versus 9.8 (4.3-NE) months (HR, 0.76; 95% CI 0.378-1.511). Median OS (95% CI) in the respective age groups was not reached (NR) (NE-NE) versus 28.6 (25.5-NE) months (HR, 0.74; 95% CI 0.541-1.022), 30.0 (30.0-NE) versus NR (NE-NE) months (HR, 0.89; 95% CI 0.546-1.467), and 25.3 (19.9-NE) versus NR (19.4-NE) months (HR, 0.87; 95% CI 0.359-2.106). ORR (95% CI) in the respective age groups was 49.4% (43.3% to 55.6%) versus 27.3% (22.1% to 32.9%), 60.9% (52.2% to 69.1%) versus 28.9% (21.2% to 37.6%), and 42.4% (25.5% to 60.8%) versus 22.0% (10.6% to 37.6%). In the avelumab plus axitinib arm, grade ≥3 adverse events (AEs) and immune-related AEs occurred in 76.9%/81.2%/72.7% and 45.5%/48.1%/36.4% in the respective age groups.ConclusionsFirst-line avelumab plus axitinib demonstrated favorable efficacy across age groups, including patients aged ≥75 years. OS data were still immature; follow-up is ongoing. The safety profile was generally consistent across age groups.
