Cost-Utility of Nivolumab Plus Ipilimumab in First-Line Treatment of Advanced Melanoma in the United States: An Analysis Using Long-Term Overall Survival Data from Checkmate 067.

ABSTRACT:

Objective

The aim of this study was to evaluate the cost-utility of nivolumab plus ipilimumab (NIVO + IPI) versus other first-line therapies for advanced melanoma in the United States (US) from the third-party payer perspective.

Methods

This analysis estimated total expected life-years (LYs), quality-adjusted LYs (QALYs), and costs for first-line treatments of advanced melanoma during a 30-year time horizon using indirect treatment comparisons based on time-varying hazard ratios (HRs) and a three-state partitioned survival model. Overall survival (OS) and progression-free survival reference curves were extrapolated based on 5-year follow-up from the phase III Checkmate 067 trial (NCT01844505). Comparators of NIVO + IPI were NIVO, IPI, pembrolizumab, dabrafenib plus trametinib, encorafenib plus binimetinib (ENCO + BINI), and vemurafenib plus cobimetinib. Drug acquisition costs, treatment administration costs, follow-up time, subsequent therapy data, and adverse event frequencies were obtained from published sources. Utility weights were estimated from Checkmate 067, which compared NIVO + IPI or NIVO monotherapy with IPI monotherapy as first-line therapy in advanced melanoma. A 3% annual discount rate was applied to costs and outcomes. Sensitivity scenarios for BRAF-mutant subgroups were conducted.

Results

NIVO + IPI was estimated to generate the longest OS and the highest total costs versus all comparators, accruing 6.99 LYs, 5.70 QALYs, and $469,469 over the 30-year time horizon. The incremental cost utility of NIVO + IPI versus comparators ranged from $2130 per QALY (versus ENCO + BINI) to $76,169 per QALY (versus NIVO). In all base-case and most sensitivity analyses, the incremental cost-utility ratios for NIVO + IPI were below $100,000 per QALY.

Conclusions

NIVO + IPI is estimated to be a life-extending and cost-effective treatment versus other therapies in the US, with base-case incremental cost-utility ratios below $100,000 per QALY.

Project description:BackgroundIn patients with melanoma, ipilimumab (an antibody against cytotoxic T-lymphocyte-associated antigen 4 [CTLA-4]) prolongs overall survival, and nivolumab (an antibody against the programmed death 1 [PD-1] receptor) produced durable tumor regression in a phase 1 trial. On the basis of their distinct immunologic mechanisms of action and supportive preclinical data, we conducted a phase 1 trial of nivolumab combined with ipilimumab in patients with advanced melanoma.MethodsWe administered intravenous doses of nivolumab and ipilimumab in patients every 3 weeks for 4 doses, followed by nivolumab alone every 3 weeks for 4 doses (concurrent regimen). The combined treatment was subsequently administered every 12 weeks for up to 8 doses. In a sequenced regimen, patients previously treated with ipilimumab received nivolumab every 2 weeks for up to 48 doses.ResultsA total of 53 patients received concurrent therapy with nivolumab and ipilimumab, and 33 received sequenced treatment. The objective-response rate (according to modified World Health Organization criteria) for all patients in the concurrent-regimen group was 40%. Evidence of clinical activity (conventional, unconfirmed, or immune-related response or stable disease for ≥24 weeks) was observed in 65% of patients. At the maximum doses that were associated with an acceptable level of adverse events (nivolumab at a dose of 1 mg per kilogram of body weight and ipilimumab at a dose of 3 mg per kilogram), 53% of patients had an objective response, all with tumor reduction of 80% or more. Grade 3 or 4 adverse events related to therapy occurred in 53% of patients in the concurrent-regimen group but were qualitatively similar to previous experience with monotherapy and were generally reversible. Among patients in the sequenced-regimen group, 18% had grade 3 or 4 adverse events related to therapy and the objective-response rate was 20%.ConclusionsConcurrent therapy with nivolumab and ipilimumab had a manageable safety profile and provided clinical activity that appears to be distinct from that in published data on monotherapy, with rapid and deep tumor regression in a substantial proportion of patients.

Project description:PurposeMetastatic esophagogastric cancer treatments after failure of second-line chemotherapy are limited. Nivolumab demonstrated superior overall survival (OS) versus placebo in Asian patients with advanced gastric or gastroesophageal junction cancers. We assessed the safety and efficacy of nivolumab and nivolumab plus ipilimumab in Western patients with chemotherapy-refractory esophagogastric cancers.Patients and methodsPatients with locally advanced or metastatic chemotherapy-refractory gastric, esophageal, or gastroesophageal junction cancer from centers in the United States and Europe received nivolumab or nivolumab plus ipilimumab. The primary end point was objective response rate. The association of tumor programmed death-ligand 1 status with response and survival was also evaluated.ResultsOf 160 treated patients (59 with nivolumab 3 mg/kg, 49 with nivolumab 1 mg/kg plus ipilimumab 3 mg/kg, 52 with nivolumab 3 mg/kg plus ipilimumab 1 mg/kg), 79% had received two or more prior therapies. At the data cutoff, investigator-assessed objective response rates were 12% (95% CI, 5% to 23%), 24% (95% CI, 13% to 39%), and 8% (95% CI, 2% to 19%) in the three groups, respectively. Responses were observed regardless of tumor programmed death-ligand 1 status. With a median follow-up of 28, 24, and 22 months across the three groups, 12-month progression-free survival rates were 8%, 17%, and 10%, respectively; 12-month OS rates were 39%, 35%, and 24%, respectively. Treatment-related grade 3/4 adverse events were reported in 17%, 47%, and 27% of patients in the three groups, respectively.ConclusionNivolumab and nivolumab plus ipilimumab demonstrated clinically meaningful antitumor activity, durable responses, encouraging long-term OS, and a manageable safety profile in patients with chemotherapy-refractory esophagogastric cancer. Phase III studies evaluating nivolumab or nivolumab plus ipilimumab in earlier lines of therapy for esophagogastric cancers are underway.

Project description:BackgroundNivolumab combined with ipilimumab resulted in longer progression-free survival and a higher objective response rate than ipilimumab alone in a phase 3 trial involving patients with advanced melanoma. We now report 3-year overall survival outcomes in this trial.MethodsWe randomly assigned, in a 1:1:1 ratio, patients with previously untreated advanced melanoma to receive nivolumab at a dose of 1 mg per kilogram of body weight plus ipilimumab at a dose of 3 mg per kilogram every 3 weeks for four doses, followed by nivolumab at a dose of 3 mg per kilogram every 2 weeks; nivolumab at a dose of 3 mg per kilogram every 2 weeks plus placebo; or ipilimumab at a dose of 3 mg per kilogram every 3 weeks for four doses plus placebo, until progression, the occurrence of unacceptable toxic effects, or withdrawal of consent. Randomization was stratified according to programmed death ligand 1 (PD-L1) status, BRAF mutation status, and metastasis stage. The two primary end points were progression-free survival and overall survival in the nivolumab-plus-ipilimumab group and in the nivolumab group versus the ipilimumab group.ResultsAt a minimum follow-up of 36 months, the median overall survival had not been reached in the nivolumab-plus-ipilimumab group and was 37.6 months in the nivolumab group, as compared with 19.9 months in the ipilimumab group (hazard ratio for death with nivolumab plus ipilimumab vs. ipilimumab, 0.55 [P<0.001]; hazard ratio for death with nivolumab vs. ipilimumab, 0.65 [P<0.001]). The overall survival rate at 3 years was 58% in the nivolumab-plus-ipilimumab group and 52% in the nivolumab group, as compared with 34% in the ipilimumab group. The safety profile was unchanged from the initial report. Treatment-related adverse events of grade 3 or 4 occurred in 59% of the patients in the nivolumab-plus-ipilimumab group, in 21% of those in the nivolumab group, and in 28% of those in the ipilimumab group.ConclusionsAmong patients with advanced melanoma, significantly longer overall survival occurred with combination therapy with nivolumab plus ipilimumab or with nivolumab alone than with ipilimumab alone.

Project description:BackgroundThe combination of ipilimumab and nivolumab is a highly effective treatment for metastatic cutaneous melanoma. However, immune-related adverse events (irAEs) are common, often necessitating treatment interruption and the use of immunosuppressive agents. There is no data on the impact of resuming nivolumab on survival following recovery from the irAE and completion of immunosuppressive treatment.Patients and methodsIn this retrospective analysis, we examined a cohort of patients treated with ipilimumab/nivolumab who developed irAEs requiring treatment interruption and immunosuppressive therapy. The differences in physician practice patterns at our institution allowed us to examine the survival effect of restarting single-agent nivolumab. A multivariate analysis of clinical factors associated with improved survival was performed.ResultsWe identified 165 patients who were treated with ipilimumab/nivolumab and developed irAEs requiring treatment interruption and immunosuppressive therapy. Patients with the best overall response of progressive disease were excluded. Of the remaining 122 patients, 46 resumed single-agent nivolumab. When stratified by age and adjusted for sex, M-stage, lactate dehydrogenase (LDH), therapy duration, and irAE type, the effect of resumption of nivolumab on survival was highly significant (p=0.02). Patients who resumed nivolumab had a 68% reduction in the hazard of death compared with patients who had not yet or never resumed nivolumab (HR: 0.32, 95% CI: 0.12 to 0.84). Of the patients who resumed nivolumab, 12 (26%) patients had subsequent irAEs, with five patients having grade 3 irAEs. No grade 4 or 5 irAEs were noted.ConclusionsResuming single-agent nivolumab following a treatment interruption for ipilimumab/nivolumab-associated irAE and completion of immunosuppressive therapy increased overall survival compared with discontinuing nivolumab permanently in patients with metastatic melanoma. Toxicity observed post-resumption of single-agent nivolumab was manageable with no severe irAEs observed.

Project description:BackgroundNivolumab plus ipilimumab demonstrated clinically meaningful improvement in efficacy versus chemotherapy with a manageable safety profile in patients with advanced non-small cell lung cancer (NSCLC) and tumor programmed death-ligand 1 (PD-L1) expression ≥1% or <1% in Part 1 of CheckMate 227. Here we report efficacy and safety results for the Asian subpopulation.MethodsPatients with stage IV/recurrent NSCLC were randomized 1 : 1 : 1 to nivolumab plus ipilimumab, nivolumab monotherapy, or chemotherapy (PD-L1 ≥1%) or nivolumab plus ipilimumab, nivolumab plus chemotherapy, or chemotherapy (PD-L1 <1%). Overall survival (OS), progression-free survival, objective response rate, duration of response, and safety were evaluated among patients in Japan, South Korea, and Taiwan.ResultsIn the Asian subpopulation with PD-L1 ≥1%, 81 patients received nivolumab plus ipilimumab and 81 received chemotherapy. Median OS was not reached with nivolumab plus ipilimumab versus 24.8 months with chemotherapy; 3-year OS rate was 53% versus 37% [hazard ratio (HR), 0.72; 95% confidence interval (CI) 0.47-1.11]. The 3-year progression-free survival rate was 26% versus 7% (HR, 0.65; 95% CI 0.45-0.96), objective response rate was 56% versus 37%, and median duration of response was 29.0 months (95% CI 15.0 months-not reached) versus 6.9 months (95% CI 3.9-11.1 months). Similar results were observed regardless of tumor PD-L1 expression and in Japanese patients. Grade 3-4 treatment-related adverse events occurred in 40% of patients receiving nivolumab plus ipilimumab and 36% receiving chemotherapy, in the overall Asian subpopulation (tumor PD-L1 expression ≥1% and <1%); no new safety signals were identified.ConclusionsAt 3-year follow-up, nivolumab plus ipilimumab provided durable long-term efficacy benefits versus chemotherapy regardless of tumor PD-L1 expression in the Asian subpopulation, including Japanese patients. Consistent with findings for all randomized patients, these data support the use of nivolumab plus ipilimumab as first-line treatment of Asian patients with advanced NSCLC.

Project description:ImportanceRecently, new drugs have been approved for the first-line treatment of metastatic renal cell carcinoma (mRCC). Nivolumab plus ipilimumab significantly increases overall survival for intermediate- and poor-risk patients with mRCC. However, considering the high cost of nivolumab plus ipilimumab, there is a need to assess its value by considering both efficacy and cost.ObjectiveTo evaluate the cost-effectiveness of nivolumab plus ipilimumab vs sunitinib in the first-line setting for intermediate- and poor-risk patients with mRCC from the US payer perspective.Design, setting, and participantsA Markov model was developed to compare the lifetime cost and effectiveness of nivolumab plus ipilimumab vs sunitinib in the first-line treatment of mRCC using outcomes data from the CheckMate 214 phase 3 randomized clinical trial, which included 1096 patients with mRCC (median age, 62 years) and compared nivolumab plus ipilimumab vs sunitinib as first-line treatment of mRCC. In the analysis, patients were modeled to receive sunitinib or nivolumab plus ipilimumab for 4 doses followed by nivolumab monotherapy.Main outcomes and measuresLife-years, quality-adjusted life-years (QALYs), and lifetime costs were estimated, at a willingness-to-pay threshold of $100 000 to $150 000 per QALY. Univariable, 2-way, and probabilistic sensitivity analyses were performed to evaluate the model uncertainty. Additional subgroup analyses were performed.ResultsNivolumab plus ipilimumab provided an additional 0.96 QALYs, at a cost of $108 363 per QALY. Sensitivity analyses found the results to be most sensitive to overall survival hazard ratio (0.63; 95% CI, 0.44-0.89) and mean patient weight (70 kg, range, 40-200 kg). Other variables, such as the cost of nivolumab plus ipilimumab (mean, $32 213.44; range, $25 770.75-$38 656.13), utility values for nivolumab plus ipilimumab (mean, 0.82; range, 0.65-0.98), and proportion receiving nivolumab in sunitinib arm (mean, 0.27; range, 0.22-0.32), had a moderate or minor influence on model results. Subgroup analyses demonstrated that nivolumab plus ipilimumab was most cost-effective for patients with programmed cell death 1 ligand 1 expression of at least 1% ($86 390 per QALY).Conclusions and relevanceIn this model, nivolumab plus ipilimumab was estimated to be cost-effective compared with sunitinib for intermediate- and poor-risk patients with mRCC at a willingness-to-pay threshold from $100 000 to $150 000 per QALY.

Project description:In the randomized, open-label, phase 3 CheckMate 214 trial, nivolumab plus ipilimumab (nivolumab 3 mg/kg plus ipilimumab 1 mg/kg every 3 wk for four doses, then nivolumab 3 mg/kg every 2 wk) had superior efficacy over sunitinib (50 mg once daily, 4 wk on, 2 wk off) in patients with untreated International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) intermediate- or poor-risk advanced renal cell carcinoma; the benefits were sustained through extended follow-up. To better characterize the association between outcomes and IMDC risk in CheckMate 214, we completed a post hoc analysis (n = 1051) of efficacy by the number of IMDC risk factors. The investigator-assessed objective response rate (ORR), overall survival (OS), and investigator-assessed progression-free survival (PFS) according to Response Evaluation Criteria in Solid Tumors v1.1 were evaluated. ORR with nivolumab plus ipilimumab was consistent across zero to six IMDC risk factors, whereas with sunitinib it decreased with increasing number of risk factors. Benefits of nivolumab plus ipilimumab over sunitinib in terms of ORR (40-44% vs 16-38%), OS (hazard ratio [HR] 0.50-0.72), and PFS (HR 0.44-0.86) were consistently observed in subgroups with one, two, three, or four to six IMDC risk factors (p < 0.05 for treatment × no. of risk factors interaction). These results demonstrate the benefit of first-line nivolumab plus ipilimumab over sunitinib across all intermediate-risk and poor-risk groups, regardless of the number of IMDC risk factors. PATIENT SUMMARY: This report from the CheckMate 214 study describes a consistent efficacy benefit with first-line nivolumab plus ipilimumab over first-line sunitinib in all groups of patients with intermediate-risk or poor-risk advanced renal cell carcinoma, regardless of the number of risk factors they had before starting treatment. We conclude that there is a benefit of first-line treatment with nivolumab plus ipilimumab for all intermediate-risk patients, including those with one or two risk factors, and for all poor-risk patients, independent of the number of risk factors.
