NCT01638676

Brief Summary

The main purpose of this study is to evaluate the safety of Vemurafenib in combination with Metformin in melanoma patients. The phase II part of the study will also evaluate the clinical activity of the combined regiment. Based on pre-clinical studies and a phase I trial, the investigators hypothesize that the combination of an FDA-approved non-toxic dose of oral Metformin with Vemurafenib will yield little toxicity and improve clinical outcomes in terms of objective response rates and survival in metastatic melanoma patients.

Outcome Measures

Primary Outcomes (1)

  • Observation of CTCAE grade 4 or higher adverse events in six patients

    In the phase I portion, six patients will be enrolled and observed for CTCAE grade 4 or higher events. If three or more grade 4 or higher adverse events are observed among the six patients, the study will be halted.

    Duration of phase I portion, approximately six months

Secondary Outcomes (4)

  • Overall Survival Follow up

    Every 12 weeks (+/- 7 days) after last drug dose, for up to 3 full years

  • Number of adverse events

    Duration of study, estimated to be approximately 60 months

  • type of adverse events

    Duration of study, estimated to be approximately 60 months

  • Objective response rate (ORR)as measure of efficacy

    Duration of study (approximately 60 months)

Study Arms (1)

  • Eastern Cooperative Oncology Group (ECOG) Performance Status(PS) of 0 to 2;
  • Life expectancy ≥ 3 months;
  • At least 1 site of radiographically measurable disease by RECIST 1.1
  • Adequate hematologic, renal, and liver function as defined by laboratory values performed within 42 days prior to initiation of dosing:
  • Absolute neutrophil count (ANC) ≥ 1.0 x 109/L;
  • Platelet count ≥ 50 x 109/L;
  • Hemoglobin ≥ 8 g/dL;
  • Serum creatinine ≤ 2 x upper limit of normal (ULN)
  • Total serum bilirubin ≤ 3 x ULN;
  • Serum aspartate transaminase (AST/SGOT) or serum alanine transaminase (ALT/SGPT) ≤ 3x ULN, and ≤ 4 x ULN if liver metastases are present.
  • Fertile males should use an effective method of contraception during treatment and for at least 3 months after completion of treatment, as directed by their physician;
  • Pre-menopausal females and females \< 2 years after the onset of menopause should have a negative pregnancy test at Screening. Pre-menopausal females must agree to use an acceptable method of birth control from the time of the negative pregnancy test up to 90 days after the last dose of study drug. Females of non-childbearing potential may be included if they are either surgically sterile or have been postmenopausal for ≥ 1 year;
  • Before study entry, written informed consent must be obtained from the patient prior to performing any study-related procedures.

You may not qualify if:

  • Prior treatment with Vemurafenib;
  • Known hypersensitivity to Metformin or any of its components;
  • Previous progression of melanoma while on Metformin;
  • Received radiotherapy for non CNS disease within the 2 weeks prior to commencing study treatment or have not recovered from side effects of all radiation-related toxicities to Grade ≤ 1, except for alopecia;
  • Pregnant, breast-feeding, or refusing double barrier contraception, oral contraceptives, or avoidance of pregnancy measures;
  • Have any other uncontrolled infection or medical condition that could interfere with the conduct of the study
