Ipilimumab in combination with nivolumab for the treatment of renal cell carcinoma.

ABSTRACT: INTRODUCTION:Renal cell carcinoma (RCC) is a highly immunogenic neoplasm, and cytokine-based immunotherapies have been used for decades with limited success. In recent years, antibody-based immunotherapies targeting immune checkpoint receptors PD-1 and CTLA-4 have demonstrated clinical efficacy in metastatic RCC (mRCC) patients, leading to FDA approval of the combination of nivolumab and ipilimumab in treatment-naïve patients with intermediate- or poor-risk disease in April 2018. Areas covered: The pharmacodynamics and pharmacokinetics of nivolumab and ipilimumab are reviewed. Clinical safety and efficacy results from pivotal phase I and III trials of the combination of nivolumab plus ipilimumab in mRCC are summarized, and the combination is reviewed in the context of other available systemic therapies for RCC. Ongoing clinical studies involving the combination of nivolumab plus ipilimumab in RCC are discussed. Expert opinion: The combination of nivolumab and ipilimumab has demonstrated superior efficacy for treatment-naïve patients with intermediate- and poor-risk mRCC with clear cell histology and is likely to replace anti-angiogenic therapies as the treatment-of-choice in this patient population in the United States. Development of additional combination strategies, novel trial designs, and predictive biomarkers of response will be important to further optimize therapeutic selection and clinical outcomes.

Project description:BackgroundNivolumab plus ipilimumab produced objective responses in patients with advanced renal-cell carcinoma in a pilot study. This phase 3 trial compared nivolumab plus ipilimumab with sunitinib for previously untreated clear-cell advanced renal-cell carcinoma.MethodsWe randomly assigned adults in a 1:1 ratio to receive either nivolumab (3 mg per kilogram of body weight) plus ipilimumab (1 mg per kilogram) intravenously every 3 weeks for four doses, followed by nivolumab (3 mg per kilogram) every 2 weeks, or sunitinib (50 mg) orally once daily for 4 weeks (6-week cycle). The coprimary end points were overall survival (alpha level, 0.04), objective response rate (alpha level, 0.001), and progression-free survival (alpha level, 0.009) among patients with intermediate or poor prognostic risk.ResultsA total of 1096 patients were assigned to receive nivolumab plus ipilimumab (550 patients) or sunitinib (546 patients); 425 and 422, respectively, had intermediate or poor risk. At a median follow-up of 25.2 months in intermediate- and poor-risk patients, the 18-month overall survival rate was 75% (95% confidence interval [CI], 70 to 78) with nivolumab plus ipilimumab and 60% (95% CI, 55 to 65) with sunitinib; the median overall survival was not reached with nivolumab plus ipilimumab versus 26.0 months with sunitinib (hazard ratio for death, 0.63; P<0.001). The objective response rate was 42% versus 27% (P<0.001), and the complete response rate was 9% versus 1%. The median progression-free survival was 11.6 months and 8.4 months, respectively (hazard ratio for disease progression or death, 0.82; P=0.03, not significant per the prespecified 0.009 threshold). Treatment-related adverse events occurred in 509 of 547 patients (93%) in the nivolumab-plus-ipilimumab group and 521 of 535 patients (97%) in the sunitinib group; grade 3 or 4 events occurred in 250 patients (46%) and 335 patients (63%), respectively. Treatment-related adverse events leading to discontinuation occurred in 22% and 12% of the patients in the respective groups.ConclusionsOverall survival and objective response rates were significantly higher with nivolumab plus ipilimumab than with sunitinib among intermediate- and poor-risk patients with previously untreated advanced renal-cell carcinoma.

Project description:IntroductionImmune checkpoint inhibitors (ICI) have been approved for front-line therapy in metastatic renal cell carcinoma (mRCC). However, progressive disease often occurs and subsequent therapies are needed. ICI rechallenge may be an option, but there is a lack of data regarding efficacy and prognostic factors. We assessed efficacy of ICI rechallenge and factors associated with better outcomes. Patients and Methods. This ambispective multicenter study included 45 mRCC patients rechallenged with nivolumab ± ipilimumab between 2014 and 2020. Primary endpoint was investigator-assessed best objective response rate (ORR) for ICI rechallenge (ICI-2). Factors associated with ICI-2 progression-free survival (PFS) were evaluated with multivariate Cox models.ResultsORR was 51% (n = 23) at first ICI therapy (ICI-1) and 16% (n = 7) for ICI-2. Median PFS was 11.4 months (95% CI, 9.8-23.5) and 3.5 months (95% CI, 2.8-9.7), and median overall survival was not reached (NR) (95% CI, 37.8-NR) and 24 months (95% CI, 9.9-NR) for ICI-1 and ICI-2, respectively. Factors associated with poorer ICI-2 PFS were a high number of metastatic sites, presence of liver metastases, use of an intervening treatment between ICI regimens, Eastern Cooperative Oncology Group performance status ≥2, and poor International Metastatic RCC Database Consortium score at ICI-2 start. Conversely, ICI-1 PFS >6 months was associated with better ICI-2 PFS. In multivariate analysis, there were only statistical trends toward better ICI-2 PFS in patients with ICI-1 PFS >6 months (p=0.07) and toward poorer ICI-2 PFS in patients who received a treatment between ICI regimens (p=0.07).ConclusionRechallenge with nivolumab-based ICI has some efficacy in mRCC. We identified various prognostic factors in univariate analysis but only statistical trends in multivariate analysis. Our findings bring new evidence on ICI rechallenge and preliminary but unique data that may help clinicians to select patients who will benefit from this strategy.

Project description:BackgroundBone metastases (BM) in renal cell carcinoma (RCC) patients are associated with poor outcomes. There are limited published data on outcomes in these patients with immunotherapy agents. We present a multi-institutional, retrospective analysis of metastatic RCC patients with BM treated with ipilimumab and nivolumab (I + N).ObjectivePatient, tumor, and treatment-related variables were retrospectively collected from electronic medical records of patients with a histologically confirmed diagnosis of RCC and at least one radiographically confirmed BM prior to initiation of I + N. Best objective response was assessed by clinical chart review, imaging reports, and treating physician evaluation; progression-free survival (PFS) and overall survival (OS) were recorded as of 31 December 2020. Descriptive statistics were used to summarize patient characteristics and BM-related variables. Kaplan-Meier method and Mantel-Haenszel log-rank test were used to compare survival among groups. Cox regression univariable and multivariable models were used to correlate patient- and treatment-related variables to outcomes.ResultsEighty patients with RCC and BM treated with I + N were identified. Patients were predominantly male and Caucasian presenting primarily with IMDC intermediate or poor-risk clear-cell RCC. Best response to I + N was progressive disease (46%), stable disease (28%), partial response (21%), and not evaluable (5%). Median PFS was 6.1 months (95% CI 3.8-8.9 months) with the majority of patients (65%) discontinuing I + N due to disease progression. Median OS was 25.6 months (95% CI 14.9-NA) with median follow-up of 25.2 months. A multivariable regression model for PFS showed several variables to be significantly associated with worse PFS including female gender [p = 0.02; hazard ratio (HR) 2.16; 95% CI 1.14-4.12], metastases to other sites (p = 0.006; HR 2.12; 95% CI 1.24-3.62) and presence of BM to ribs (p = 0.0007; HR 2.61; 95% CI 1.50-4.52). A multivariable Cox model of OS showed no prior radiation therapy to BM (p = 0.02; HR 2.17; 95% CI 1.13-4.17) and presence of liver metastases (p = 0.0006; HR 3.19; 95% CI 1.65-6.19) to be significantly associated with worse OS.ConclusionRCC patients with ≥ 1 BM who received I + N therapy had a relatively low response rate, PFS, and OS. Strategies to improve outcomes in this subset of patients are needed.

Project description:PurposeTo determine the value of tumor cell programmed death-ligand 1 (PD-L1) expression as a predictive biomarker of nivolumab monotherapy efficacy in treatment-naive patients with clear cell renal cell carcinoma (ccRCC) and the efficacy of salvage nivolumab/ipilimumab in patients with tumors unresponsive to nivolumab monotherapy.MethodsEligible patients with treatment-naive ccRCC received nivolumab until progressive disease (PD), toxicity, or completing 96 treatment weeks (part A). Patients with PD before or stable disease at 48 weeks could receive salvage nivolumab/ipilimumab (part B). The primary end point was improvement in 1-year progression-free survival in patients with tumor PD-L1 expression > 20% versus 0%.ResultsOne hundred twenty-three patients were enrolled. The objective response rate (ORR) was 34.1% (95% CI, 25.8 to 43.2). ORR by International Metastatic RCC Database Consortium category was favorable-risk 57.1%, intermediate-risk/poor-risk 25.0%, and by sarcomatoid features 36.4%. The ORR was 26.9%, 50.0%, and 75.0% for patients with the tumor PD-L1 expression of 0, 1-20, or > 20%, respectively (trend test P value = .002). The median duration of response was 27.6 (19.3 to not reached) months, with 26 of 42 responders including 17 of 20 with favorable-risk disease remaining progression-free. The 1-year progression-free survival was 34.6% and 75.0% in the PD-L1 = 0% and > 20% categories, respectively (P = .050). Ninety-seven patients with PD or prolonged stable disease were potentially eligible for part B, and 35 were enrolled. The ORR for part B was 11.4%. Grade ≥ 3 treatment-related adverse events occurred in 35% of patients on nivolumab and 43% of those on salvage nivolumab/ipilimumab.ConclusionNivolumab monotherapy is active in treatment-naive ccRCC. Although efficacy appears to be less than that of nivolumab/ipilimumab in patients with intermediate-risk/poor-risk disease, favorable-risk patients had notable benefit. Efficacy correlated with tumor PD-L1 status. Salvage nivolumab/ipilimumab was frequently not feasible and of limited benefit.

Project description:BackgroundNivolumab and ipilimumab combination therapy is approved in Japan for unresectable or metastatic renal cell carcinoma. Because the clinical trials supporting the approval of nivolumab and ipilimumab combination therapy included relatively few Japanese patients, post-marketing surveillance was implemented to collate further safety data for nivolumab and ipilimumab combination therapy.MethodsPatients with unresectable or metastatic renal cell carcinoma who started nivolumab and ipilimumab combination therapy between September 2018 and December 2019 were registered in this post-marketing surveillance. The observation period was 13 weeks. Safety data included treatment-related adverse events with a particular emphasis on the gastrointestinal-related (colitis, enteritis, diarrhoea and gastrointestinal perforation) and liver-related (hepatic failure, hepatic function abnormal, hepatitis and cholangitis sclerosing) treatment-related adverse events that are listed in the risk management plan for nivolumab and ipilimumab combination therapy.ResultsOf the 203 patients registered, safety data were available for 159 (119 males/40 females) with a median age of 67 years (range 22-88). Seventy-one patients received nivolumab and ipilimumab combination therapy four times per usual clinical therapy, and 33 continued nivolumab monotherapy thereafter. Any-grade treatment-related adverse events were reported in 102 (64.2%) patients and grade ≥ 3 in 63 (39.6%). Hepatic function abnormalities (13.2%), rash (8.8%) and interstitial lung disease (7.5%) were the most common treatment-related adverse events. Five patients died following treatment-related adverse events. Gastrointestinal-related and liver-related treatment-related adverse events occurred in 10 (6.3%; four with grade ≥ 3 treatment-related adverse events) and 27 (17.0%; 19 with grade ≥ 3 treatment-related adverse events) patients, respectively.ConclusionsThis post-marketing surveillance in patients with unresectable or metastatic renal cell carcinoma revealed a safety profile for nivolumab and ipilimumab combination therapy consistent with CheckMate 214. Furthermore, no new safety concerns were identified including gastrointestinal-related and liver-related treatment-related adverse events.
