Combination of Targeted Therapy (Encorafenib and Binimetinib) Followed by Combination of Immunotherapy (Ipilimumab and Nivolumab) vs Immediate Combination of Immunotherapy in Patients With Unresectable or Metastatic Melanoma With BRAF V600 Mutation : an EORTC Randomized Phase II Study (EBIN)

Overview
Brief Summary
This is a multicenter, 2-arm open-label, randomized comparative phase II study. The objective of this trial is to prospectively evaluate whether a sequential approach with an induction period of 12 weeks with encorafenib + binimetinib followed by combination immunotherapy with nivolumab + ipilimumab improves progression free survival compared to combination immunotherapy nivolumab + ipilimumab alone in patients with BRAF V600 mutation-positive unresectable or metastatic melanoma.

Inclusion Criteria
- •Histologically or cytologically confirmed unresectable stage III or IV cutaneous or mucosal melanoma
- •Presence of BRAF V600E or V600K mutation in tumor tissue prior to enrolment as per local assessment
- •Tumor tissue from an unresectable or metastatic site of disease must be provided for biomarker analyses. This can be an archived sample if obtained at maximum 3 months prior to randomization and if the patient did not receive treatment since then.
- •Measurable disease per RECIST 1.1 criteria by computed tomography (CT) or Magnetic Resonance Imaging (MRI) of Chest/Abdomen/Pelvis CT and brain CT/MRI performed within 28 days prior to randomization
- •Patients ≥ 18 years of age
- •Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0 or 1
- •Patients must be able to swallow and retain oral tablets
- •Adequate organ function within 14 days prior to randomization
- •Patients with hyperthyroidism or hypothyroidism but that are stable on hormone replacement can be included.
- •Adequate cardiac function
Exclusion Criteria
- •Uveal melanoma
- •Any symptomatic brain or leptomeningeal disease. Subjects with brain metastases are eligible if these have been locally treated and there is no magnetic resonance imaging (MRI) evidence of progression for at least 4 weeks after treatment and treatment is completed within 28 days prior to first dose of study drug administration. There must also be no requirement for immunosuppressive doses of systemic corticosteroids (\> 10 mg/day prednisone equivalents) for at least 2 weeks prior to study drug administration.
- •Any prior treatment for advanced disease including treatment with an anti-Programmed Death receptor-1 (PD-1), anti-Programmed Death-1 ligand-1 (PD-L1), anti-PD-L2, anti-cytotoxic T lymphocyte associated antigen-4 (anti-CTLA-4) antibody, anti-LAG-3, anti-TIM-3, anti-IDO, etc or BRAF or MEK inhibitors.
- •History of hypersensitivity to study drugs or any excipient (refer to Investigator's brochures for binimetinib and encorafenib and SmPCs for ipilimumab and nivolumab).
- •Prior adjuvant melanoma therapy with IFN, anti-PD1, anti-PDL1 or anti-CTLA-4 or any other systemic treatment is permitted if completed at least 1 year prior to randomization and all related adverse events have either returned to ≤
- •Concomitant administration of strong inducers and inhibitors of P-gp, glucuronidation, CYP3A4 (e.g. rifampicin, rifabutin, carbamazepine, phenytoin or St John's Wort \[hypericin\])
- •Concomitant anticoagulation at therapeutic doses with oral anticoagulants (eg, warfarin)
- •Live vaccines within 30 days prior to the first dose of study therapy. Examples of live vaccines include, but are not limited to, the following: measles, mumps, rubella, chicken pox, yellow fever, H1N1 flu, rabies, BCG, and typhoid vaccine.
- •Current participation or treatment with other investigational agent or use of an investigational device within 4 weeks of the first dose of study treatment
- •Child-Pugh B/C and patients with history of acute or chronic pancreatitis
Arms & Interventions
ARM A: Nivolumab + Ipilimumab
nivolumab 3 mg/kg q3w + ipilimumab 1 mg/kg q3w for 4 injections followed by nivolumab 480 mg IV q4w until completion of 2 years total treatment or progression. Then treatment will be left at the investigator choice and continued until the 2nd progression.
Intervention: Nivolumab + Ipilimumab (Drug)
ARM B: Encorafenib + Binimetinib + Nivolumab + Ipilimumab
encorafenib 450 mg QD + binimetinib 45 mg BID orally for 12 weeks followed, after a week of pause, by nivolumab 3 mg/kg q3w + ipilimumab 1 mg/kg q3w for 4 injections, followed by nivolumab 480 mg IV q4w until completion of 2 years total treatment or progression. Then patients will be rechallenged with encorafenib 450 mg QD + binimetinib 45 mg BID orally continuously until the 2nd progression.
Intervention: Nivolumab + Ipilimumab (Drug)
ARM B: Encorafenib + Binimetinib + Nivolumab + Ipilimumab
encorafenib 450 mg QD + binimetinib 45 mg BID orally for 12 weeks followed, after a week of pause, by nivolumab 3 mg/kg q3w + ipilimumab 1 mg/kg q3w for 4 injections, followed by nivolumab 480 mg IV q4w until completion of 2 years total treatment or progression. Then patients will be rechallenged with encorafenib 450 mg QD + binimetinib 45 mg BID orally continuously until the 2nd progression.
Intervention: Encorafenib + Binimetinib (Drug)
Outcomes
Primary Outcomes
