Overview
Brief Summary
This phase II trial studies the side effects and how well nivolumab with trametinib and dabrafenib, or encorafenib and binimetinib work in treating patients with BRAF-mutated stage III-IV melanoma that has spread to other places in the body (metastatic) or cannot be removed by surgery (unresectable). Immunotherapy with monoclonal antibodies, such as nivolumab, may induce changes in the body's immune system and may interfere with the ability of tumor cells to grow and spread. Trametinib, dabrafenib, encorafenib, and binimetinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known if nivolumab with trametinib and dabrafenib, or encorafenib and binimetinib may work better in treating patients with BRAF-mutated melanoma.
Detailed Description
PRIMARY OBJECTIVE:
I. To determine the safety, tolerability, and efficacy (objective response rates by Response Evaluation Criteria in Solid Tumors [RECIST] 1.1) of nivolumab in combination with dabrafenib and trametinib or encorafenib and binimetinib in patients with BRAF-mutated metastatic melanoma.
SECONDARY OBJECTIVES:
I. Safety and tolerability of the nivolumab, dabrafenib, and trametinib triplet combination (NDT).
II. Safety and tolerability of the nivolumab, binimetinib and encorafenib. III. Efficacy of the combination as measured by the depth and duration of response by RECIST 1.1 and modified RECIST 1.1 (to include intracranial response).
IV. Pharmacodynamic evaluation of combination on circulating markers (immune monitoring).
V. Pharmacodynamic evaluation of combination on tumor tissues. VI. Progression- free survival and overall survival.
OUTLINE: Patients are assigned to 1 of 3 arms.
ARM A (NDT, CLOSED): Patients receive nivolumab intravenously (IV) over 30 minutes on day 1, dabrafenib orally (PO) twice daily (BID) on days 1-28, and trametinib PO once daily (QD) on days 1-28. Cycles repeats every 28 days for up to 3 years in the absence of disease progression or unacceptable toxicity.
ARM B (NT, CLOSED TO ACCRUAL): Patients receive nivolumab IV over 30 minutes on day 1 and 15, and trametinib PO QD on days 1-28. Cycles repeats every 28 days for up to 3 years in the absence of disease progression or unacceptable toxicity.
ARM C (NEB): Patients receive nivolumab IV over 30 minutes on day 1 and 15, encorafenib PO QD on days 1-28, and binimetinib PO BID on days 1-28. Cycles repeats every 28 days for up to 3 years in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 30 days then every 3 months for up to 3 years.

Inclusion Criteria
- •Histologically confirmed metastatic melanoma (stage IV) or unresectable Stage III that have progressed on or after receiving prior PD-1 directed therapy; only patients with BRAF V600 mutated melanoma are eligible; please note that patients with brain metastasis are not required to have prior PD-1
- •Prior therapies for metastatic melanoma are allowed, including chemo-, cytokine-, immuno, biological and vaccine-therapy as long as they did not include BRAFi, MEKi; patients who have progressed on or after receiving anti-PD-1therapy in the adjuvant setting are also allowed; prior ipilimumab and/or PD-1 directed therapy will be allowed with a washout period of 2 weeks and if all autoimmune adverse events have resolved to grade 1 (except endocrine abnormalities that require continuous replacement)
- •Evidence of evaluable disease
- •Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
- •Patients with melanoma brain metastases are allowed regardless of prior PD-1 exposure. Subjects with brain metastases are eligible if:
- •Metastases have been treated and there is no magnetic resonance imaging (MRI) evidence of progression for 2 weeks after treatment is complete and within 14 days of the first dose of nivolumab administration; or
- •If they are untreated but asymptomatic; or
- •If they are untreated and symptomatic but symptoms are controlled on stable or decreasing doses of steroids for 14 days prior to drug administration; or
- •If they have untreated leptomeningeal disease (LMD) as long as they fulfill all other eligibility requirements.
- •Note: Patients are excluded if they require high doses of systemic corticosteroids (\> 8 mg equivalent of dexamethasone) to control central nervous system (CNS) symptoms.
Exclusion Criteria
- •Patients that had grade 3/4 immune-related adverse events (AEs) on ipilimumab or nivolumab that required more than 12 weeks of immune suppression with corticosteroids
- •History of interstitial lung disease or pneumonitis
- •History of known glucose-6-phosphate dehydrogenase (G6PD) deficiency
- •Active, known or suspected autoimmune disease; subjects are permitted to enroll if they have vitiligo, type I diabetes mellitus, residual hypothyroidism and/or hypophysitis due to autoimmune condition only requiring hormone replacement, psoriasis not requiring systemic treatment, or conditions not expected to recur in the absence of an external trigger
- •Require systemic treatment with either corticosteroids (\> 8 mg daily prednisone equivalents) or other immunosuppressive medications within 14 days of study drug administration; inhaled or topical steroids and adrenal replacement doses are permitted in the absence of active autoimmune disease
- •Known history of a positive test for hepatitis B virus or hepatitis C virus indicating acute or chronic infection
- •Known history of testing positive for human immunodeficiency virus (HIV) or known acquired immunodeficiency syndrome (AIDS); HIV-positive patients on combination antiretroviral therapy are ineligible because of the potential for pharmacokinetic interactions with dabrafenib and trametinib; in addition, these patients are at increased risk of lethal infections when treated with marrow-suppressive therapy; appropriate studies will be undertaken in patients receiving combination antiretroviral therapy when indicated
- •History of allergy or adverse drug reaction to the study drug components (nivolumab, dabrafenib, or trametinib) or drugs of similar chemical or biologic composition; patients with a history of severe hypersensitivity reaction to any monoclonal antibody should also be excluded
- •Patients who have had chemotherapy or radiotherapy within 2 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study or those who have not recovered from adverse events due to agents administered more than 4 weeks earlier
- •Uncontrolled intercurrent illness (requiring IV antibiotic treatment) including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
