In a randomized trial involving patients with previously untreated advanced renal-cell carcinoma, nivolumab plus cabozantinib had significant benefits over sunitinib with respect to progression-free and overall survival and the likelihood of response. A total of 19.7% of the patients in the combination group discontinued one or both of the trial drugs prematurely.

Abstract Background Patients with nonmetastatic castration-resistant prostate cancer (nmCRPC) are usually asymptomatic and seek treatments that improve survival but have a low risk of adverse events. Darolutamide, a structurally distinct androgen receptor inhibitor (ARi), significantly reduced the risk of metastasis and death versus placebo in ARAMIS. We assessed the extended safety and tolerability of darolutamide and the time-course profile of treatment-emergent adverse events (TEAEs) related to ARis and androgen-suppressive treatment. Patients and Methods Patients with nmCRPC were randomized 2:1 to darolutamide (n = 955) or placebo (n = 554). After trial unblinding, patients could receive open-label darolutamide. Tolerability and TEAEs were assessed every 16 weeks. Time interval–specific new and cumulative event rates were determined during the first 24 months of the double-blind period. Results Darolutamide remained well tolerated during the double-blind and open-label periods, with 98.8% of patients receiving the full planned dose. The incidence of TEAEs of interest in the darolutamide group was low and ≤2% different from that in the placebo group, except for fatigue. When incidences were adjusted for exposure time, there were minimal differences between the darolutamide double-blind and double-blind plus open-label periods. The rate of initial onset and cumulative incidence of grade 3/4 TEAEs and serious TEAEs were similar for darolutamide and placebo groups over 24 months. Conclusion Extended treatment with darolutamide was well tolerated and no new safety signals were observed. Most ARi-associated and androgen-suppressive treatment–related TEAEs occurred at low incidences with darolutamide, were similar to placebo, and showed minimal increase over time with continued treatment. Trial number ClinicalTrials.gov identifier NCT02200614 This report examines darolutamide tolerability from extended follow-up for both the double-blind and open-label treatment periods of the phase III ARAMIS trial and characterizes the onset and occurrence over time of treatment-emergent adverse events of interest, including those commonly associated with androgen receptor inhibitor therapy and androgen-suppressive treatment.

Androgen receptor pathway inhibitors (ARPIs) and docetaxel are established standards of care for chemotherapy-naive metastatic castration-resistant prostate cancer (mCRPC). We aimed to assess the efficacy and safety of adding nivolumab to docetaxel versus docetaxel alone in ARPI-pretreated, chemotherapy-naive mCRPC. CheckMate 7DX was a double-blind, randomised, phase 3 trial that enrolled adult patients (aged ≥18 years) with histologically confirmed, ARPI-pretreated, and chemotherapy-naive mCRPC at 291 hospitals and cancer centres across 27 countries. Patients had documented progression within 6 months of screening and an Eastern Cooperative Oncology Group performance status of 0 or 1. Patients were randomly assigned (1:1) to nivolumab (360 mg), or equivalent placebo, and docetaxel (75 mg/m2) intravenously every 3 weeks for up to ten doses, followed by nivolumab (480 mg) or equivalent placebo every 4 weeks. Randomisation, stratified by previous ARPI therapy and visceral disease, was done using interactive response technology in permuted blocks with a block size of six. Patients, investigators, and the trial sponsor were masked to individual patient treatment assignment. The primary endpoints were radiographic progression-free survival by blinded independent central review and overall survival, assessed in all randomly assigned patients. Safety was assessed in all patients who received at least one dose of study drug. This study is registered with ClinicalTrials.gov, NCT04100018, and is completed. Between March 11, 2020, and Aug 2, 2022, 1414 patients were screened for eligibility, 1030 of whom were randomly assigned to nivolumab plus docetaxel (n=514) or placebo plus docetaxel (n=516). All participants were male, median age was 70 years (range 34–91), 662 (64%) were White, 240 (23%) were Asian, and 35 (3%) were Black or African American. With a median follow-up of 17·2 months (IQR 13·2–22·0), median radiographic progression-free survival was 9·4 months (95% CI 8·5–10·3) in the nivolumab plus docetaxel group versus 8·7 months (95% CI 8·4–10·0) in the placebo plus docetaxel group (hazard ratio [HR] 0·96 [99% CI 0·77–1·19]; p=0·59) and median overall survival was 18·7 months (95% CI 17·0–21·0) versus 18·9 months (95% CI 17·3–22·0, HR 1·09 [99·41% CI 0·84–1·43]; p=0·36). Grade 3–4 treatment-related adverse events occurred in 223 (44%) of 510 patients in the nivolumab plus docetaxel group and 187 (37%) of 510 in the placebo plus docetaxel group. The most common grade 3–4 events in both treatment groups were neutropenia (37 [7%] in the nivolumab plus docetaxel group and 50 [10%] in the placebo plus docetaxel group) and decreased neutrophil count (41 [8%] and 39 [8%]). Any-grade treatment-related serious adverse events occurred in 107 (21%) patients in the nivolumab plus docetaxel group and 77 (15%) in the placebo plus docetaxel group. 12 deaths were attributed to nivolumab plus docetaxel (three due to sepsis; one each due to Guillain–Barré syndrome, diverticulitis, myocarditis, liver injury, peritonitis, pneumonitis, pneumonia, and diarrhoea; and one due to unknown causes) and one was attributed to placebo plus docetaxel (due to pneumocystis). Nivolumab plus docetaxel did not improve progression-free survival or overall survival versus placebo plus docetaxel in patients with ARPI-pretreated, chemotherapy-naive mCRPC. These findings do not support the use of combinations of anti-PD-1 immune checkpoint inhibitors and docetaxel in the treatment of unselected populations of patients with ARPI-pretreated, chemotherapy-naive mCRPC.

BackgroundCheckpoint inhibitor therapy has demonstrated overall survival benefit in multiple tumor types. Tumor mutational burden (TMB) is a predictive biomarker for response to immunotherapies. This study evaluated the efficacy of nivolumab+ipilimumab in multiple tumor types based on TMB status evaluated using either tumor tissue (tTMB) or circulating tumor DNA in the blood (bTMB).Patients and methodsPatients with metastatic or unresectable solid tumors with high (≥10 mutations per megabase) tTMB (tTMB-H) and/or bTMB (bTMB-H) who were refractory to standard therapies were randomized 2:1 to receive nivolumab+ipilimumab or nivolumab monotherapy in an open-label, phase 2 study (CheckMate 848; NCT03668119). tTMB and bTMB were determined by the Foundation Medicine FoundationOne® CDx test and bTMB Clinical Trial Assay, respectively. The dual primary endpoints were objective response rate (ORR) in patients with tTMB-H and/or bTMB-H tumors treated with nivolumab+ipilimumab.ResultsIn total, 201 patients refractory to standard therapies were randomized: 135 had tTMB-H and 125 had bTMB-H; 82 patients had dual tTMB-H/bTMB-H. In patients with tTMB-H, ORR was 38.6% (95% CI 28.4% to 49.6%) with nivolumab+ipilimumab and 29.8% (95% CI 17.3% to 44.9%) with nivolumab monotherapy. In patients with bTMB-H, ORR was 22.5% (95% CI 13.9% to 33.2%) with nivolumab+ipilimumab and 15.6% (95% CI 6.5% to 29.5%) with nivolumab monotherapy. Early and durable responses to treatment with nivolumab+ipilimumab were seen in patients with tTMB-H or bTMB-H. The safety profile of nivolumab+ipilimumab was manageable, with no new safety signals.ConclusionsPatients with metastatic or unresectable solid tumors with TMB-H, as determined by tissue biopsy or by blood sample when tissue biopsy is unavailable, who have no other treatment options, may benefit from nivolumab+ipilimumab.Trial registration number NCT03668119.

Inherited variations in drug metabolizing enzymes may influence drug efficacy. This phase II study assesses the impact of second-line weekly irinotecan (CPT-11)/docetaxel in non-small cell lung cancer (NSCLC) patients, and gauges the uridine diphosphate glucuronosyl transferase (UGT1A1) polymorphism influence in toxicity and antitumor activity. Fifty-one patients with NSCLC treated with at least one prior chemotherapy regimen were enrolled. Patients received irinotecan 70 mg/m(2) followed by docetaxel 25 mg/m(2). Both drugs were given on days 1, 8, and 15 every 28 days. UGT1A1 polymorphism were analyzed in blood samples of 47 patients. The UGT1A1 polymorphism are classified according to the number of TA repeats in the promoter region of this gene. Three patients (6%) achieved a partial response and nineteen patients (37%) had stable disease. Median survival was 8 months (95% CI: 4.8-11.2) and 1-year survival 30%. Grade 3-4 hematologic toxicity was low (less than 10% of patients); 15% of patients had grade 3 asthenia and 25% of patients had grade 3/4 diarrhea. The frequency of UGT1A1 genotypes was as follows: 6/6 49%, 6/7 36%, and 7/7 15%. No differences in toxicity were observed according to UGT1A1 polymorphism. A nonsignificant improvement in time to progression (4 vs. 3 months) and median survival (11 vs. 8 months) was detected in patients with the variant alleles (6/7 and 7/7). This weekly irinotecan/docetaxel regimen has shown an acceptable toxicity profile while encouraging median and 1-year survival in heavily pretreated NSCLC patients. The tendency to better prognosis in patients carrying the variant genotypes 6/7 and 7/7 of UGT1A1 gene requires further validation.

BackgroundIn CheckMate 9LA, nivolumab plus ipilimumab with chemotherapy prolonged overall survival (OS) versus chemotherapy regardless of tumor PD-L1 expression or histology. We report updated efficacy and safety in all randomized patients with a minimum 4-year follow-up and an exploratory treatment-switching adjustment analysis in all treated patients who received chemotherapy and subsequent immunotherapy.MethodsAdults with stage IV/recurrent non-small cell lung cancer (NSCLC), no sensitizing EGFR/ALK alterations, and ECOG performance status ≤1 were randomized 1:1 to nivolumab 360 mg every 3 weeks plus ipilimumab 1 mg/kg every 6 weeks with chemotherapy (two cycles) or chemotherapy (four cycles, with optional maintenance pemetrexed for the nonsquamous population). Assessments included OS, progression-free survival, and objective response rate. Exploratory analyses included efficacy by tumor PD-L1 expression and histology and in patients who discontinued nivolumab plus ipilimumab with chemotherapy due to treatment-related adverse events (TRAEs), and a treatment-switching adjustment analysis using inverse probability of censoring weighting.ResultsWith a 47.9-month minimum follow-up for OS, nivolumab plus ipilimumab with chemotherapy continued to prolong OS over chemotherapy in all randomized patients (HR 0.74, 95% CI 0.63 to 0.87; 4-year OS rate: 21% versus 16%), regardless of tumor PD-L1 expression (HR (95% CI): PD-L1<1%, 0.66 (0.50 to 0.86) and ≥1%, 0.74 (0.60 to 0.92)) or histology (squamous, 0.64 (0.48 to 0.84) and non-squamous, 0.80 (0.66 to 0.97)). In patients who discontinued all components of nivolumab plus ipilimumab with chemotherapy due to TRAEs (n=61), the 4-year OS rate was 41%. With treatment-switching adjustment for the 36% of patients receiving subsequent immunotherapy in the chemotherapy arm, the estimated HR of nivolumab plus ipilimumab with chemotherapy versus chemotherapy was 0.66 (95% CI 0.55 to 0.80). No new safety signals were observed.ConclusionsIn this 4-year update, patients treated with nivolumab plus ipilimumab with chemotherapy continued to have long-term, durable efficacy benefit over chemotherapy regardless of tumor PD-L1 expression and/or histology. A greater estimated relative OS benefit was observed after adjustment for subsequent immunotherapy use in the chemotherapy arm. These results further support nivolumab plus ipilimumab with chemotherapy as a first-line treatment for patients with metastatic/recurrent NSCLC, including those with tumor PD-L1<1% or squamous histology, populations with high unmet needs.

First-line nivolumab plus ipilimumab has shown improved overall survival in patients with advanced non-small-cell lung cancer (NSCLC). We aimed to investigate whether the addition of a limited course (two cycles) of chemotherapy to this combination would further enhance the clinical benefit. This randomised, open-label, phase 3 trial was done at 103 hospitals in 19 countries. Eligible patients were aged 18 years or older with treatment-naive, histologically confirmed stage IV or recurrent NSCLC, and an Eastern Cooperative Oncology Group performance status of 0–1. Patients were randomly assigned (1:1) by an interactive web response system via permuted blocks (block size of four) to nivolumab (360 mg intravenously every 3 weeks) plus ipilimumab (1 mg/kg intravenously every 6 weeks) combined with histology-based, platinum doublet chemotherapy (intravenously every 3 weeks for two cycles; experimental group), or chemotherapy alone (every 3 weeks for four cycles; control group). Randomisation was stratified by tumour histology, sex, and PD-L1 expression. The primary endpoint was overall survival in all randomly assigned patients. Safety was analysed in all treated patients. Results reported here are from a pre-planned interim analysis (when the study met its primary endpoint) and an exploratory longer-term follow-up analysis. This study is active but no longer recruiting patients, and is registered with ClinicalTrials.gov, number NCT03215706. Between Aug 24, 2017, and Jan 30, 2019, 1150 patients were enrolled and 719 (62·5%) randomly assigned to nivolumab plus ipilimumab with two cycles of chemotherapy (n=361 [50%]) or four cycles of chemotherapy alone (n=358 [50%]). At the pre-planned interim analysis (median follow-up 9·7 months [IQR 6·4–12·8]), overall survival in all randomly assigned patients was significantly longer in the experimental group than in the control group (median 14·1 months [95% CI 13·2–16·2] vs 10·7 months [9·5–12·4]; hazard ratio [HR] 0·69 [96·71% CI 0·55–0·87]; p=0·00065). With 3·5 months longer median follow-up (median 13·2 months [IQR 6·4–17·0]), median overall survival was 15·6 months (95% CI 13·9–20·0) in the experimental group versus 10·9 months (9·5–12·6) in the control group (HR 0·66 [95% CI 0·55–0·80]). The most common grade 3–4 treatment-related adverse events were neutropenia (in 24 [7%] patients in the experimental group vs 32 [9%] in the control group), anaemia (21 [6%] vs 50 [14%]), diarrhoea (14 [4%] vs two [1%]), increased lipase (22 [6%] vs three [1%]), and febrile neutropenia (14 [4%] vs ten [3%]). Serious treatment-related adverse events of any grade occurred in 106 (30%) patients in the experimental group and 62 (18%) in the control group. Seven (2%) deaths in the experimental group (acute kidney failure, diarrhoea, hepatotoxicity, hepatitis, pneumonitis, sepsis with acute renal insufficiency, and thrombocytopenia; one patient each) and six (2%) deaths in the control group (anaemia, febrile neutropenia, pancytopenia, pulmonary sepsis, respiratory failure, and sepsis; one patient each) were treatment related. Nivolumab plus ipilimumab with two cycles of chemotherapy provided a significant improvement in overall survival versus chemotherapy alone and had a favourable risk–benefit profile. These data support this regimen as a new first-line treatment option for patients with advanced NSCLC. Bristol Myers Squibb.
