Patient perspectives on ipilimumab across the melanoma treatment trajectory.

ABSTRACT: PURPOSE:Ipilimumab was the first FDA-approved agent for advanced melanoma to improve survival and represents a paradigm shift in melanoma and cancer treatment. Its unique toxicity profile and kinetics of treatment response raise novel patient education challenges. We assessed patient perceptions of ipilimumab therapy across the treatment trajectory. METHODS:Four patient cohorts were assessed at different time points relative to treatment initiation: (1) prior to initiation of ipilimumab (n = 10), (2) at weeks 10-12 before restaging studies (n = 11), (3) at week 12 following restaging studies indicating progression of disease (n = 10), and (4) at week 12 following restaging studies indicating either a radiographic response or disease stability (n = 10). Patients participated in a semistructured qualitative interview to assess their experiences with ipilimumab. Quality of life was assessed via the Functional Assessment of Cancer Therapy-General and its Melanoma-specific module. RESULTS:Perceived quality of life was comparable across cohorts, and a majority of the sample understood side effects from ipilimumab and the potential for a delayed treatment response. Patients without progression of disease following restaging studies at week 12 held more positive views regarding ipilimumab compared to patients who had progressed. CONCLUSION:Patients generally regarded ipilimumab positively despite the risk of unique toxicities and potential for delayed therapeutic responses; however, those with progression expressed uncertainty regarding whether taking ipilimumab was worthwhile. Physician communication practices and patient education regarding realistic expectations for therapeutic benefit as well as unique toxicities associated with ipilimumab should be developed so that patients can better understand the possible outcomes from treatment.

Project description:ImportanceCytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) blockade with ipilimumab prolongs survival in patients with metastatic melanoma. CTLA-4 blockade and granulocyte-macrophage colony-stimulating factor (GM-CSF)-secreting tumor vaccine combinations demonstrate therapeutic synergy in preclinical models. A key unanswered question is whether systemic GM-CSF (sargramostim) enhances CTLA-4 blockade.ObjectiveTo compare the effect of ipilimumab plus sargramostim vs ipilimumab alone on overall survival (OS) in patients with metastatic melanoma.Design, setting, and participantsThe Eastern Cooperative Oncology Group (ECOG) conducted a US-based phase 2 randomized clinical trial from December 28, 2010, until July 28, 2011, of patients (N = 245) with unresectable stage III or IV melanoma, at least 1 prior therapy, no central nervous system metastases, and ECOG performance status of 0 or 1.InterventionsPatients were randomized to receive ipilimumab, 10 mg/kg, intravenously on day 1 plus sargramostim, 250 μg subcutaneously, on days 1 to 14 of a 21-day cycle (n = 123) vs ipilimumab alone (n = 122). Ipilimumab treatment included induction for 4 cycles followed by maintenance every fourth cycle.Main outcomes and measuresPrimary end point: comparison of length of OS. Secondary end point: progression-free survival (PFS), response rate, safety, and tolerability.ResultsMedian follow-up was 13.3 months (range, 0.03-19.9). Median OS as of December 2012 for ipilimumab plus sargramostim was 17.5 months (95% CI, 14.9-not reached) vs 12.7 months (95% CI, 10.0-not reached) for ipilimumab. The 1-year survival rate for ipilimumab plus sargramostim was 68.9% (95% CI, 60.6%-85.5%) compared to 52.9% (95% CI, 43.6%-62.2%) for ipilimumab alone (stratified log-rank 1-sided P = .01; mortality hazard ratio 0.64 [1-sided 90% repeated CI, not applicable-0.90]). A planned interim analysis was conducted at 69.8% of expected events (104 observed with 149 expected deaths). Planned interim analysis using the O'Brien-Fleming boundary was crossed for improvement in OS. There was no difference in PFS. Median PFS for ipilimumab plus sargramostim was 3.1 months (95% CI, 2.9-4.6) vs 3.1 months (95% CI, 2.9-4.0) for ipilimumab alone. Grade 3 to 5 adverse events occurred in 44.9% (95% CI; 35.8%-54.4%) of patients in the ipilimumab plus sargramostim group vs 58.3% (95% CI, 49.0%-67.2%) of patients in the ipilimumab-alone group (2-sided P = .04).Conclusion and relevanceAmong patients with unresectable stage III or IV melanoma, treatment with ipilimumab plus sargramostim vs ipilimumab alone resulted in longer OS and lower toxicity, but no difference in PFS. These findings require confirmation in larger studies with longer follow-up.Trial registrationclinicaltrials.gov Identifier: NCT01134614.

Project description:BackgroundIn a phase 1 dose-escalation study, combined inhibition of T-cell checkpoint pathways by nivolumab and ipilimumab was associated with a high rate of objective response, including complete responses, among patients with advanced melanoma.MethodsIn this double-blind study involving 142 patients with metastatic melanoma who had not previously received treatment, we randomly assigned patients in a 2:1 ratio to receive ipilimumab (3 mg per kilogram of body weight) combined with either nivolumab (1 mg per kilogram) or placebo once every 3 weeks for four doses, followed by nivolumab (3 mg per kilogram) or placebo every 2 weeks until the occurrence of disease progression or unacceptable toxic effects. The primary end point was the rate of investigator-assessed, confirmed objective response among patients with BRAF V600 wild-type tumors.ResultsAmong patients with BRAF wild-type tumors, the rate of confirmed objective response was 61% (44 of 72 patients) in the group that received both ipilimumab and nivolumab (combination group) versus 11% (4 of 37 patients) in the group that received ipilimumab and placebo (ipilimumab-monotherapy group) (P<0.001), with complete responses reported in 16 patients (22%) in the combination group and no patients in the ipilimumab-monotherapy group. The median duration of response was not reached in either group. The median progression-free survival was not reached with the combination therapy and was 4.4 months with ipilimumab monotherapy (hazard ratio associated with combination therapy as compared with ipilimumab monotherapy for disease progression or death, 0.40; 95% confidence interval, 0.23 to 0.68; P<0.001). Similar results for response rate and progression-free survival were observed in 33 patients with BRAF mutation-positive tumors. Drug-related adverse events of grade 3 or 4 were reported in 54% of the patients who received the combination therapy as compared with 24% of the patients who received ipilimumab monotherapy. Select adverse events with potential immunologic causes were consistent with those in a phase 1 study, and most of these events resolved with immune-modulating medication.ConclusionsThe objective-response rate and the progression-free survival among patients with advanced melanoma who had not previously received treatment were significantly greater with nivolumab combined with ipilimumab than with ipilimumab monotherapy. Combination therapy had an acceptable safety profile. (Funded by Bristol-Myers Squibb; ClinicalTrials.gov number, NCT01927419.).

Project description:ImportanceTreatment-free survival (TFS) represents an alternative time-to-event end point, accurately characterizing time spent free of systemic therapy, providing a more patient-centric view of immune checkpoint inhibitor (ICI) therapy regimens. There remains a lack of studies evaluating TFS outcomes among patients with advanced melanoma who are receiving immunotherapy, especially outside of the clinical trial setting.ObjectiveTo evaluate TFS outcomes for patients with advanced melanoma receiving first-line ICI therapy outside of a clinical trial setting.Design, setting, and participantsThis multicenter cohort study of patients with advanced melanoma receiving first-line ICI therapy between August 1, 2013, and May 31, 2020, was conducted in Alberta, Canada. Data analysis was performed in August 2022.ExposuresPatients received standard-of-care, first-line ICI therapy treatment regimens including single-agent nivolumab, single-agent pembrolizumab, or ipilimumab-nivolumab.Main outcomes and measuresTreatment-free survival was defined as the difference in the 36-month restricted mean survival time between 2 conventional survival end points: (1) time from treatment initiation to ICI cessation, death, or censoring at last follow-up and (2) time from treatment initiation to subsequent systemic anticancer therapy, death, or censoring at last follow-up.ResultsA total of 316 patients with advanced melanoma receiving first-line nivolumab (n = 51; median age, 66 years [IQR, 56-78 years]; 31 men [60.8%]), pembrolizumab (n = 158; median age, 69 years [IQR, 60-78 years]; 112 men [70.9%]), or combination nivolumab-ipilimumab (n = 107; median age, 53 years [IQR, 42-60 years]; 72 men [67.3%]) were included. Treatment groups were similar with regard to sex, primary tumor location, and presence of metastasis, although patients receiving combination nivolumab-ipilimumab had a lower Eastern Cooperative Oncology Group status, were younger, and were more likely to be BRAF V600E positive than those receiving anti-programmed cell death protein 1 (anti-PD-1) monotherapy. The restricted mean TFS was longer for nivolumab-ipilimumab (12.4 months [95% CI, 8.8-16.0 months]) compared with nivolumab (8.9 months [95% CI, 4.4-13.5 months]) and pembrolizumab (11.1 months [95% CI, 8.5-13.8 months]). During the 36-month follow-up interval, patients treated with nivolumab-ipilimumab spent 34.4% of their time (12.4 of 36 months) not receiving systemic anticancer treatments compared with 30.8% (11.1 of 36 months) and 24.7% (8.9 of 36 months) of the time for the pembrolizumab and nivolumab treatment groups, respectively.Conclusions and relevanceThis cohort study of patients with advanced melanoma receiving first-line ICI therapy suggests that TFS represents a patient-centric, informative end point. Patients treated with combination nivolumab-ipilimumab spent more time alive and free from systemic anticancer therapy than those treated with anti-PD-1 monotherapy alone.

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.
