CheckMate 025 Randomized Phase 3 Study: Outcomes by Key Baseline Factors and Prior Therapy for Nivolumab Versus Everolimus in Advanced Renal Cell Carcinoma.

The randomized, phase 3 CheckMate 025 study of nivolumab (n=410) versus everolimus (n=411) in previously treated adults (75% male; 88% white) with advanced renal cell carcinoma (aRCC) demonstrated significantly improved overall survival (OS) and objective response rate (ORR). To investigate which baseline factors were associated with OS and ORR benefit with nivolumab versus everolimus. Subgroup OS analyses were performed using Kaplan-Meier methodology. Hazard ratios were estimated using the Cox proportional hazards model. Nivolumab 3mg/kg every 2 wk or everolimus 10mg once daily. The minimum follow-up was 14 mo. Baseline subgroup distributions were balanced between nivolumab and everolimus arms. Nivolumab demonstrated an OS improvement versus everolimus across subgroups, including Memorial Sloan Kettering Cancer Center (MSKCC) and International Metastatic Renal Cell Carcinoma Database Consortium risk groups; age <65 and ≥65 yr; one and two or more sites of metastases; bone, liver, and lung metastases; number of prior therapies; duration of prior therapy; and prior sunitinib, pazopanib, or interleukin-2 therapy. The benefit with nivolumab versus everolimus was noteworthy for patients with poor MSKCC risk (hazard ratio 0.48, 95% confidence interval 0.32-0.70). The mortality rate at 12 mo for all subgroups was lower with nivolumab compared with everolimus. ORR also favored nivolumab. The incidence of grade 3 or 4 treatment-related adverse events across subgroups was lower with nivolumab. Limitations include the post hoc analysis and differing sample sizes between groups. The trend for OS and ORR benefit with nivolumab for multiple subgroups, without notable safety concerns, may help to guide treatment decisions, and further supports nivolumab as the standard of care in previously treated patients with aRCC. We investigated the impact of demographic and pretreatment features on survival benefit and tumor response with nivolumab versus everolimus in advanced renal cell carcinoma (aRCC). Survival benefit and response were observed for multiple subgroups, supporting the use of nivolumab as a new standard of care across a broad range of patients with previously treated aRCC. The trial is registered on ClinicalTrials.gov as NCT01668784.

Nivolumab versus everolimus in patients with advanced renal cell carcinoma: Updated results with long-term follow-up of the randomized, open-label, phase 3 CheckMate 025 trial.

CheckMate 025 has shown superior efficacy for nivolumab over everolimus in patients with advanced renal cell carcinoma (aRCC) along with improved safety and tolerability. This analysis assesses the long-term clinical benefits of nivolumab versus everolimus. The randomized, open-label, phase 3 CheckMate 025 trial (NCT01668784) included patients with clear cell aRCC previously treated with 1 or 2 antiangiogenic regimens. Patients were randomized to nivolumab (3 mg/kg every 2 weeks) or everolimus (10 mg once a day) until progression or unacceptable toxicity. The primary endpoint was overall survival (OS). The secondary endpoints were the confirmed objective response rate (ORR), progression-free survival (PFS), safety, and health-related quality of life (HRQOL). Eight hundred twenty-one patients were randomized to nivolumab (n = 410) or everolimus (n = 411); 803 patients were treated (406 with nivolumab and 397 with everolimus). With a minimum follow-up of 64 months (median, 72 months), nivolumab maintained an OS benefit in comparison with everolimus (median, 25.8 months [95% CI, 22.2-29.8 months] vs 19.7 months [95% CI, 17.6-22.1 months]; hazard ratio [HR], 0.73; 95% CI, 0.62-0.85) with 5-year OS probabilities of 26% and 18%, respectively. ORR was higher with nivolumab (94 of 410 [23%] vs 17 of 411 [4%]; P < .001). PFS also favored nivolumab (HR, 0.84; 95% CI, 0.72-0.99; P = .0331). The most common treatment-related adverse events of any grade were fatigue (34.7%) and pruritus (15.5%) with nivolumab and fatigue (34.5%) and stomatitis (29.5%) with everolimus. HRQOL improved from baseline with nivolumab but remained the same or deteriorated with everolimus. The superior efficacy of nivolumab over everolimus is maintained after extended follow-up with no new safety signals, and this supports the long-term benefits of nivolumab monotherapy in patients with previously treated aRCC. CheckMate 025 compared the effects of nivolumab (a novel immunotherapy) with those of everolimus (an older standard-of-care therapy) for the treatment of advanced kidney cancer in patients who had progressed on antiangiogenic therapy. After 5 years of study, nivolumab continues to be better than everolimus in extending the lives of patients, providing a long-lasting response to treatment, and improving quality of life with a manageable safety profile. The results demonstrate that the clinical benefits of nivolumab versus everolimus in previously treated patients with advanced kidney cancer continue in the long term.

Nivolumab plus ipilimumab versus sunitinib in previously untreated advanced renal-cell carcinoma: analysis of Japanese patients in CheckMate 214 with extended follow-up.

Nivolumab plus ipilimumab (NIVO+IPI) demonstrated superior efficacy over sunitinib (SUN) for previously untreated advanced renal cell carcinoma (aRCC) in CheckMate 214, with a manageable safety profile. We report efficacy and safety with extended follow-up amongst Japanese patients. CheckMate 214 patients received NIVO (3 mg/kg) plus IPI (1 mg/kg) every 3 weeks for four doses, then NIVO (3 mg/kg) every 2 weeks; or SUN (50 mg) once daily for 4 weeks (6-week cycle). This subgroup analysis assessed overall survival (OS), objective response rate (ORR) and progression-free survival (PFS) per investigator in International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) intermediate/poor-risk and intent-to-treat (ITT) patients and safety (ITT patients). Of 550 and 546 patients randomized to NIVO+IPI and SUN, 38 and 34, respectively, were Japanese. Of these, 31 (NIVO+IPI) and 29 (SUN) patients were IMDC intermediate/poor-risk. In IMDC intermediate/poor-risk patients with 30 months' minimum follow-up, there was a delayed trend in OS benefit with NIVO+IPI (hazard ratio [HR] 0.56; 95% confidence interval [CI]: 0.19-1.59; P = 0.2670), and 24-month OS probability favoured NIVO+IPI (84%) versus SUN (76%). The ORR was 39% with NIVO+IPI and 31% with SUN (P = 0.6968). PFS was similar in both treatment arms (HR 1.17; 95% CI: 0.62-2.20; P = 0.6220). Efficacy in ITT patients was similar to IMDC intermediate/poor-risk patients. Grade 3-4 treatment-related adverse event incidence was lower with NIVO+IPI versus SUN (58 versus 91%). Japanese patients with untreated aRCC in the NIVO+IPI arm had a numerically higher ORR and improved safety profile versus patients in the SUN arm. A delayed OS benefit appears to be emerging with NIVO+IPI. Longer follow-up is needed. https://clinicaltrials.gov/ct2/show/NCT02231749?term=NCT02231749&rank=1 identifier: NCT02231749.

Treatment Beyond Progression in Patients with Advanced Renal Cell Carcinoma Treated with Nivolumab in CheckMate 025.

Response patterns to nivolumab differ from those seen with other approved targeted therapies. To investigate the efficacy of nivolumab in previously treated patients with advanced renal cell carcinoma who were treated beyond (Response Evaluation Criteria In Solid Tumors) RECIST progression. This was a subgroup analysis of patients treated with nivolumab in the phase 3 CheckMate 025 study. Patients continuing to tolerate therapy and exhibiting investigator-assessed clinical benefit were eligible to be treated beyond RECIST progression (TBP) and received therapy for ≥4 wk after first progression; patients not treated beyond RECIST progression (NTBP) received 0 wk to <4 wk of therapy after progression. Nivolumab 3mg/kg intravenously every 2 wk. Of 406 nivolumab-treated patients, 316 (78%) progressed by RECIST criteria. Of those who progressed, 48% were TBP, 52% were NTBP. Before being TBP, objective response rate (95% confidence interval) was 20% (14-28) and 14% (9-21) in patients TBP and NTBP, respectively. Differences in clinical characteristics assessed at first progression between patients TBP versus NTBP included better Karnofsky performance status, less deterioration in Karnofsky performance status, shorter time to response, lower incidence of new bone lesions, and improved quality of life. Postprogression, 13% of all patients TBP (20/153) had ≥30% tumor burden reduction including patients with preprogression and postprogression tumor measurements (n=142) and complete/partial response (28%, 8/29), stable disease (6%, 3/47), and progressive disease (14%, 9/66) as their best response before being TBP. Incidence of treatment-related adverse events in patients TBP was lower after (59%) versus before (71%) progression. Limitations included potential bias from the nonrandomized nature of the analysis. A subset of patients with advanced renal cell carcinoma and RECIST progression experienced tumor reduction postprogression with nivolumab, and had an acceptable safety profile. Clinical judgment remains essential when switching therapy. ClinicalTrials.gov Identifier: NCT01668784. A subset of patients with advanced renal cell carcinoma and disease progression may continue to benefit from nivolumab treatment beyond progression as evidenced by tumor reduction postprogression and an acceptable safety profile.

Quality of life in patients with advanced renal cell carcinoma given nivolumab versus everolimus in CheckMate 025: a randomised, open-label, phase 3 trial.

In the phase 3 CheckMate 025 study, previously treated patients with advanced renal cell carcinoma who were randomly assigned to nivolumab had an overall survival benefit compared with those assigned to everolimus. We aimed to compare health-related quality of life (HRQoL) between treatment groups in this trial. CheckMate 025 was an open-label study done at 146 oncology centres in 24 countries. Patients were randomly assigned to treatment between Oct 22, 2012, and March 11, 2014. Patients with advanced renal cell carcinoma were randomly assigned (1:1, block size of four) to receive nivolumab every 2 weeks or everolimus once per day. The study was stopped early at the planned interim analysis in July, 2015, because the study met its primary endpoint. A protocol amendment permitted patients in the everolimus group to cross over to nivolumab treatment. All patients not on active study therapy are being followed up for survival. At the interim analysis, HRQoL was assessed with the Functional Assessment of Cancer Therapy-Kidney Symptom Index-Disease Related Symptoms (FKSI-DRS) and European Quality of Life (EuroQol)-5 Dimensions (EQ-5D) questionnaires. Prespecified endpoints were to assess, in each treatment group, disease-related symptom progression rate based on the FKSI-DRS and changes in reported global health outcomes based on the EQ-5D. Other endpoints were post hoc. We calculated the proportion of FKSI-DRS questionnaires completed using the number of patients with non-missing data at baseline and at least one post-baseline visit. We defined FKSI-DRS completion as completion of five or more of the nine items in the questionnaire; otherwise data were treated as missing. FKSI-DRS symptom index score was prorated for missing items. We made no adjustments for missing EQ-5D data. We used descriptive statistics and multivariate analyses, including mixed-effects model repeated-measures, for between group comparisons. Analyses were powered according to the original study protocol, and we analysed FKSI-DRS and EQ-5D data for all patients who underwent randomisation and had a baseline assessment and at least one post-baseline assessment. CheckMate 025 is registered with ClinicalTrials.gov, number NCT01668784. HRQoL data were collected at baseline for 362 (88%) of 410 patients in the nivolumab group and 344 (84%) of 411 patients in the everolimus group. The mean difference in FKSI-DRS scores between the nivolumab and everolimus groups was 1·6 (95% CI 1·4-1·9; p<0·0001) with descriptive statistics and 1·7 (1·2-2·1; p<0·0001) with mixed-effects model repeated-measures analysis. In terms of FKSI-DRS score, more patients had a clinically meaningful (ie, an increase of at least 2 points from baseline) HRQoL improvement with nivolumab (200 [55%] of 361 patients) versus everolimus (126 [37%] of 343 patients; p<0·0001). Median time to HRQoL improvement was shorter in patients given nivolumab (4·7 months, 95% CI 3·7-7·5) than in patients given everolimus (median not reached, NE-NE). Nivolumab was associated with HRQoL improvement compared with everolimus in previously treated patients with advanced renal cell carcinoma. Bristol-Myers Squibb.
