Nevertheless, it takes time till responses occur and still a significant number of patients do not benefit from treatment, due to rapid progressive disease or resistance to therapy.\n\nIn contrast to immunotherapies targeted therapies (BRAF or MEK inhibitors), can induce faster and higher response rates, but often of shorter duration, even when combined.\n\nInitial attempts of combining vemurafenib or dabrafenib + trametinib with ipilimumab failed due to toxicity.\n\nPatients with elevated levels of serum LDH are less likely to respond to immunotherapy compared to patients with normal LDH levels. This does not mean that such patients do not benefit at all from immunotherapy.\n\nThis raises the question, whether response rates upon immunotherapy can be improved by upfront reduction of tumor burden and normalization of LDH.\n\nThe investigators postulate that induction therapy with combined BRAF+MEK inhibition, and subsequent LDH normalization, can improve response rates to the rates seen in LDH normal patients.\n\nTo address this question the investigators have setup a randomized phase 2 trial in metastatic melanoma patients with elevated serum LDH comparing the response rates upon ipilimumab + nivolumab versus ipilimumab + nivolumab preceded by 6 weeks of vemurafenib + cobimetinib induction.\n\nFurthermore, less than half of the patients treated with the combination of ipilimumab and nivolumab received maintenance nivolumab, and approximately 40% of all patients discontinued treatment for toxicity. In 70% of patients responses were ongoing despite discontinuation of treatment due to toxicity. This raises the question, to what extent does maintenance therapy add clinical benefit to an ongoing immune response. Preclinical data indicate even that continuous restimulation of T cells can result in activation induced non-responsiveness (anergy).\n\nTherefore, a secondary objective of this trial will be, to test a response-driven nivolumab scheme\n\nObjectives:\n\nPrimary Objective • To compare efficacy of induction vemurafenib + cobimetinib followed by ipilimumab + nivolumab (Arm A) versus upfront ipilimumab + nivolumab treatment (Arm B).\n\nSecondary Objectives\n\n* To describe duration of response and overall survival induced by vemurafenib + cobimetinib followed by the combination of ipilimumab + nivolumab (Arm A) as compared to ipilimumab + nivolumab (Arm B)\n* To describe the rate and quality of toxicity observed in the two study arms\n* To describe the rate of ongoing responses upon response-driven flat dose (240mg q2w or 480mg q4w) nivolumab maintenance\n* To determine the immune-activating capacity of induction therapy with vemurafenib + cobimetinib followed by the combination of ipilimumab + nivolumab.\n* To evaluate the changes in systemic immune competence\n\nStudy design:\n\nThis is a two-arm phase 2 study consisting of 200 BRAFV600E/K mutation-positive late-stage melanoma patients with an elevated baseline LDH level (\\> ULN, \\< 3xULN) randomized 1:1 (stratified according to LDH) to receive either vemurafenib + cobimetinib directly followed by ipilimumab + nivolumab (Arm A) or standard first line ipilimumab + nivolumab (Arm B). Subsequently, patients in both arms will receive flat dose (240mg q2w or 480mg q4w) nivolumab maintenance in a response-driven manner.\n\nStudy population:\n\nStage IV, or unresectable stage III, BRAFV600E/K mutation positive melanoma patients, naïve for BRAF/MEK, PD-1/PD-L1 or CTLA-4 targeting therapy, 18 years and older.\n\nIntervention:\n\nPatients will be randomized 1:1 to receive either 6 weeks vemurafenib 960 mg bid + cobimetinib 60 mg QD 21-day on, 7-day off (21/7) schedule, directly followed by 4 courses of ipilimumab 3mg/kg q3wk + nivolumab 1mg/kg q3wk (Arm A) or first line standard 4 courses of ipilimumab 3mg/kg q3wk + nivolumab 1mg/kg q3wk (Arm B).\n\nSubsequently, patients in both arms will receive nivolumab maintenance flat dose (240mg q2w or 480mg q4w) in a response-driven manner according to their response at week 18.\n\nMain study parameters/endpoints:\n\nPrimary Endpoints\n\n• Compare the best overall response rate (BORR) according to RECIST 1.1 of both arms at week 18 from start of treatment.\n\nSecondary Endpoints\n\n* Progression-free survival (PFS) according to RECIST 1.1\n* Overall survival (OS)\n* Percentage of grade 3/4 toxicities according to CTCv4.03\n* Percentage of ongoing response, percentage of patients requiring re-induction, response percentage upon re-induction\n* Changes in tumor-specific T cell responses'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n* Adults 18 years and older\n* World Health Organization (WHO) Performance Status 0-2\n* Histologically or cytologically confirmed Stage IV, or unresectable stage III, BRAF V600E/K mutated melanoma\n* Measurable disease according to RECIST 1.1\n* Signed and dated informed consent form\n* No prior immunotherapy targeting CTLA-4, PD-1 or PD-L1\n* No prior BRAFi and/ or MEKi therapy\n* No immunosuppressive medications\n* Screening laboratory values must meet the following criteria and should be obtained within 10 days prior to randomization:\n\n * WBC ≥ 2.0x109/L, Neutrophils ≥ 1.0x109/L, Platelets ≥ 100 x109/L, Hemoglobin ≥ 5.0 mmol/L\n * Creatinine ≤ 2x ULN or creatinine clearance (CrCl) ≥ 40 ml/min\n * AST, ALT ≤ 3.0 x ULN (≤5 x ULN for patients with liver metastases)\n * Bilirubin ≤ 2.0 x ULN (except subjects with Gilbert Syndrome, who can have total bilirubin \\< 3.0 mg/dL )\n * LDH \\> ULN, \\< 5.0 x ULN\n* No symptomatic brain metastases (asysmptomatic brain metastases, accidentally found during screening can be included)\n* No leptomeningeal metastases\n* No active autoimmune disease requiring systemic treatment in the past 3 months or a documented history of autoimmune disease, or history of syndrome that required systemic steroids, at daily dose of ≥10mg prednisone or equivalent, or immunosuppressive medications.
