Brief Summary:

This randomized phase III trial studies how well initial treatment with ipilimumab and nivolumab followed by dabrafenib and trametinib works and compares it to initial treatment with dabrafenib and trametinib followed by ipilimumab and nivolumab in treating patients with stage III-IV melanoma that contains a mutation known as BRAFV600 and cannot be removed by surgery. Ipilimumab and nivolumab may block tumor growth by targeting certain cells. Dabrafenib and trametinib may block tumor growth by targeting the BRAFV600 gene. It is not yet known whether treating patients with ipilimumab and nivolumab followed by dabrafenib and trametinib is more effective than treatment with dabrafenib and trametinib followed by ipilimumab and nivolumab.

Outcome Measures

Go to 

Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :

1. Overall survival (OS) rate, defined as the proportion of patients alive after 2 years of follow-up time [ Time Frame: The time from randomization to death from any cause, assessed for up to 2 years ]
   Will be estimated and compared between the two arms using the Mantel-Haenszel test based (stratified by Eastern Cooperative Oncology Group (ECOG) performance status [PS] and LDH) based on two-sided overall type I error rate of 0.05 adjusting for two-interim analysis. Mantel-Haenszel test will compare the 2-year OS rates while controlling for the stratification factors. The difference in 2-year OS rates in arms A and B will be estimated and presented with 95% repeated confidence interval of Jennison-Turnbull. In addition, OS distribution will be estimated using the Kaplan-Meier method. The distribution of OS will be compared using the stratified log rank test. Hazard of OS will be estimated as a function of time in arm A and in arm B (as randomized in step 1 to arm A versus [vs.] B) and presented graphically.

Secondary Outcome Measures :

1. Progression-free survival (PFS), evaluated based on Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 [ Time Frame: The time from randomization to disease progression or death (whichever occurs first), assessed up to 5 years ]
   Distribution will be estimated using the Kaplan-Meier method. PFS will be compared using the log-rank test.
2. Response rate according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 [ Time Frame: Up to 5 years ]
   Response rates will be compared using the Mantel-Haenszel test (stratified by ECOG PS and LDH) test in arms A vs. B. Response rate for patients who are treated with ipilimumab/nivolumab before crossover (arm A) vs. for patients who were initially treated with dabrafenib/trametinib and crossed over to ipilimumab/nivolumab will be compared (arm D). Response rates will be compared using the Fisher's exact test.
3. Toxicity rate for individual adverse events (AEs) [ Time Frame: Up to 5 years ]
   Compared using the chi-square of Fisher's exact test. Two-sided p-values will be reported for these comparisons.
4. Toxicity rate for categorized adverse events (AEs) [ Time Frame: Up to 5 years ]
   Compared using the chi-square of Fisher's exact test. Two-sided p-values will be reported for these comparisons.
5. Toxicity rate for worst degree adverse events (AEs) [ Time Frame: Up to 5 years ]
   Compared using the chi-square of Fisher's exact test. Two-sided p-values will be reported for these comparisons.

Other Outcome Measures:

1. Genetic characteristics [ Time Frame: Baseline ]
   Genetic associations with immune-related adverse events (irAE) status will be assessed using Fisher's exact test, one-degree-of-freedom genotypic trend test or the two-degrees-of-freedom chi-squared test of independence at each individual SNP marker. Tests of association will be adjusted for age, sex, center or clinical protocol, and dose as well as American Joint Committee on Cancer stage, ulceration, performance status, LDH level, number of involved sites, BRAF mutation status (when available) and number of prior therapies using logistic regression modeling assuming an additive genetic model.
2. Immune-related adverse events (irAE) status [ Time Frame: Up to 2 years ]
   Genetic associations with irAE status will be assessed using Fisher's exact test, one-degree-of-freedom genotypic trend test or the two-degrees-of-freedom chi-squared test of independence at each individual SNP marker. Tests of association will be adjusted for age, sex, center or clinical protocol, and dose as well as American Joint Committee on Cancer stage, ulceration, performance status, LDH level, number of involved sites, BRAF mutation status (when available) and number of prior therapies using logistic regression modeling assuming an additive genetic model.
3. Quality-adjusted time without symptoms of disease progression or toxicity of treatment (Q-TWIST) [ Time Frame: Up to 2 years ]
   The restricted mean amount of time for each health state will be estimated using the Kaplan-Meier method, with time limit set at 2 years for computation of all restricted means. The mean amount of time for each health state and the average group utility scores will be summarized by initial treatment (i.e., arm A: ipilimumab + nivolumab [with subsequent dabrafenib + trametinib] vs. arm B: dabrafenib + trametinib [with subsequent ipilimumab + nivolumab]). The Q-TWiST subscore and the overall Q-TWiST score will then be reported by initial treatment. Differences between treatment groups in the mean Q-TWiST score (including the overall score and the subscore) will be calculated. For each score, a 95% confidence interval and two-sided P-value for testing the null hypothesis of no difference between treatment groups will be conducted using a Z-test (with normal approximation), with standard errors calculated by the bootstrap method.
4. Overall function, assessed using Patient-Reported Outcomes Measurement Information System (PROMIS) PROFILE-29 [ Time Frame: Up to 24 months from study entry ]
   A log-normal survival model for analyzing longitudinal data which incorporates the non-ignorable censoring mechanism will be fitted for each short form T-score and pain intensity, separately, to assess initial treatment effect (i.e., arm A: ipilimumab + nivolumab [with subsequent dabrafenib + trametinib] vs. arm B: dabrafenib + trametinib [with subsequent ipilimumab + nivolumab]) on each function. To evaluate the effect of treatment sequence on patient function, each of the PROMIS short form T-score and pain intensity (with longitudinal data collected at baseline, 6-, 12-weeks, and 6-months after the initiation of treatment in each step) will be compared by treatment sequence for ipilimumab + nivolumab (arm A vs. D) and for dabrafenib + trametinib (arm B vs. C), using a log-normal survival model as described above.
5. Change in patient-reported symptoms, assessed using the Patient Reported Outcomes Common Terminology Criteria for Adverse Events [ Time Frame: Baseline to up to 6 months after the initiation of treatment in each step ]
   To evaluate the effect of treatment sequence on symptoms, summary statistics (frequency [N] and percentage [%]) will be reported with respect to presence, frequency and severity (if applicable) for each symptom by treatment sequence for ipilimumab + nivolumab (arm A vs. D), and for dabrafenib + trametinib (arm B vs. C) at baseline, 6-, 12-weeks, and 6-months after the initiation of the first treatment and the secondary treatment.
