Brief Summary:
This study will evaluate the clinical and pathological response to vemurafenib and cobimetinib in the neoadjuvant treatment of patients with histologically confirmed, BRAF V600 mutation-positive Stage IIIB and C melanoma. 20 patients will be treated with vemurafenib and cobimetinib for 2 months. Then they will be assessed for surgery. Patients will undergo surgery and subsequently resume taking vemurafenib and cobimetinib after recovery from surgery. Patients will undergo radiation therapy if appropriate then continue vemurafenib and cobimetinib. The maximum treatment period is 12 months. After 12 months of treatment, patients will be followed for disease recurrence and survival during for a total of 5 years.

Condition or disease Intervention/treatment Phase
Melanoma Drug: Vemurafenib Drug: Cobimetinib Phase 2

Detailed Description:

At Screening: Assessments will include CT or MRI of the brain, CT of chest, abdomen and pelvis, dermatology assessment, head and neck exam, pelvic and anal exam, ophthalmology exam, electrocardiogram (ECG), echocardiogram (ECHO) or multigated acquisition (MUGA) scan, a history and physical exam. A core biopsy will be performed within 14 days of study entry.

During Treatment: The maximum treatment period is 12 months. Patients will be assessed monthly while on treatment. Assessments performed will include vital signs assessment and physical exam, dermatology exam, ophthalmology exam, echocardiogram (ECHO) or multigated acquisition (MUGA) scan, electrocardiogram (ECG), safety blood tests, pelvic and anal exam.

Follow-up after treatment: Patients will be followed for 5 years. Radiology exams will be done to assess for disease. Other assessments performed include vital signs assessment and physical exam, dermatology exam, include echogram (ECHO) or multigated acquisition (MUGA) scans.

Criteria

Inclusion Criteria:

  1. Naïve to treatment for locally advanced unresectable disease (Stage IIIB and C). Prior adjuvant therapy (including immunotherapy, e.g., ipilimumab) is allowed if prior to nodal recurrence and ≥ 3 months have elapsed from the last day of adjuvant therapy to start of study treatment2. Biopsy proven unresected melanoma with palpable regional lymph node.
  2. Biopsy proven unresected melanoma patients with palpable regional lymph node metastases, presenting with AJCC stage IIIB-C or with recurrent regional lymphadenopathy that are not suitable or not prefered for surgcal intervention.
  3. BRAF V600 mutation positive.
  4. Eastern Cooperative Oncology Group performance status of 0 or 1.
  5. Measurable disease per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1
  6. Adequate hematologic, renal and liver function within 7 days prior to the first dose of vemurafenib and cobimetinib.
  7. Agree to always use an effective form(s) of contraception beginning from the informed consent signature date until at least 6 months after completion of study therapy.
  8. Negative serum pregnancy test within 14 days prior to start of treatment in women of childbearing potential only.
  9. Absence of any psychological, familial, sociological, or geographical condition potentially hampering compliance with the study protocol and follow-up schedule.

Exclusion Criteria:

  1. Cannot have received any prior therapy for the current recurrence or nodal disease. Previous adjuvant immunotherapy is allowed if prior to nodal recurrence and ≥ 3 months have elapsed from the last day of adjuvant therapy to start of study treatment.
