Arm Intervention/treatment
Experimental: Cobimetinib in Combination with Vemurafenib

Vemurafenib (960 mg twice a day) will be taken on Days 1 - 28 of each 28-day treatment cycle. The first dose of vemurafenib should be taken in the morning, and the second dose should be taken in the evening. Vemurafenib can be taken with or without a meal and should be taken with a glass of water.

Cobimetinib (60 mg once a day) will be taken on Days 1 - 21 of each 28-day treatment cycle. The cobimetinib tablet should be taken at approximately the same time each day in the morning with the vemurafenib dose, but no later than 4 hours after the scheduled time. Cobimetinib can be taken with or without a meal and should never be chewed, cut, or crushed and should be taken with a glass of water.

Drug: Cobimetinib

Primary Outcome Measures :
  1. Objective Intracranial Response (OIRR) [ Time Frame: Until disease progression, less than or equal to 5 years. ]
    Change in overall size of the sum of diameters from baseline of up to 5 intracranial target lesions in response to study treatment, achieved by individual patients.


Secondary Outcome Measures :
  1. Overall Response [ Time Frame: Until disease progression, less than or equal to 5 years. ]
    Response to study treatment achieved by individual patients as indicated by an overall change in size of the sum of diameters from baseline of up to 5 intracranial target lesions and up to 5 extracranial target lesions.

  2. Progression-free Survival (PFS) [ Time Frame: Up to 5 years ]
    Time (number of months) from first documented evidence of overall Complete Response (CR) or Partial Response (PR) until time of first documented disease progression or death due to any cause (for individual patients). Progression as defined by RECIST 1.1 (Response Evaluation Criteria In Solid Tumors) is a ≥ 20% increase in the sum of the diameters of target lesions, taking as a reference, the smallest sum of diameters recorded since the treatment started (e.g. percent change from nadir, where nadir is defined as the smallest sum of diameters recorded since treatment start). In addition, the sum must have an absolute increase from nadir of 5mm.

  3. Overall Survival (OS) [ Time Frame: Up to 5 years ]
    Number of months of survival for individual patients.

  4. Duration of Response [ Time Frame: Until disease progression, less than or equal to 5 years. ]
    Change in relative apparent diffusion coefficient (rADC) as measured by MRI as early predictor of response value/result for each patient

  5. Immune Modulation in Peripheral Blood [ Time Frame: Up to 5 years ]
  6. Early Markers of Progression in Peripheral Blood [ Time Frame: Up to 5 years ]
  7. Health-related Quality of Life as Measured by The Functional Assessment of Cancer Therapy (FACT) - Brain (FACT-Br) [ Time Frame: Up to 5 years ]
    The Functional Assessment of Cancer Therapy-Brain (FACT-Br) is used to measure general quality of life (QOL) that reflects symptoms or problems associated with brain malignancies across 5 scales. The brain subscale is usually used along with the core (general) questionnaire that includes 27 items. The measure yields information about total QOL, as well as information about the dimensions of physical well-being, social/family well-being, emotional well being, functional well-being, and disease-specific concerns. Patients rate all 5 items using a five-point Likert scale ranging from 0 "not at all" to 4 "very much." Overall, higher ratings suggest higher QOL. Items are totaled to produce the following subscales, along with an overall QOL score: physical well-being (7 items); social/family well-being (7 items); emotional well-being (6 items); functional well-being (7 items); and concerns relevant to patients with brain tumors (23 items). Scoring range is 0-200.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Signed informed consent
  • Histologically confirmed metastatic melanoma (Stage IV), carrying BRAF V600-mutation
  • Melanoma must be documented to contain a BRAFV600 mutation by a CLIA approved laboratory
  • At least one measurable intracranial target lesion for which all of the following criteria are met:

    1. previously untreated or progressive according to RECIST 1.1 (equal to or greater than 20% increase in longest diameter on baseline scan) after previous local therapy (SRS and/or craniotomy)
    2. immediate local therapy clinically not indicated or patient is not a suitable candidate to receive immediate local therapy (SRS and/or craniotomy)
    3. largest diameter of ≥ 0.5cm but ≤ 4 cm as determined by contrast-enhanced MRI
  • Prior therapies for extracranial metastatic melanoma including chemo-, cytokine-, immuno-, biological- and vaccine-therapy will be allowed but prior BRAF or MEK not allowed
  • ECOG PS 0-2
  • Life expectancy >12 weeks
  • Age 18 years or older
  • Adequate bone marrow function as indicated by the following:

    1. ANC > 1500/µL
    2. Platelets ≥ 100,000/µL
    3. Hemoglobin > 9 g/dL
  • Adequate renal function, as indicated by creatinine =/< 1.5 x the upper limit of normal (ULN)
  • Adequate liver function, as indicated by bilirubin =/< 1.5 x ULN
  • AST or ALT < 3 x ULN (patients with documented liver metastases: AST and/or ALT =/< 5 x ULN)

Effective methods of contraception are defined as those which result in a low failure rate (i.e., less than 1% per year) when used consistently and correctly (for example implants, injectables, combined oral contraception or intra-uterine devices). At the discretion of the Investigator, acceptable methods of contraception may include total abstinence in cases where the lifestyle of the patient ensures compliance. (Periodic abstinence [e.g., calendar, ovulation, symptothermal, post-ovulation methods] and withdrawal are not acceptable methods of contraception.)
