A Phase I/II Trial of Vemurafenib and Metformin to Melanoma Patients
Overview[ - collapse ][ - ]
Purpose | 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. |

Current Primary Outcome Measures | Observation of CTCAE grade 4 or higher adverse events in six patients [Time Frame: Duration of phase I portion, approximately six months] [Designated as safety issue: Yes]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. |

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. |
Detailed Description | This is a Phase I/II study. Phase I will be evaluating the safety of the FDA-approved Vemurafenib (960 mg orally, daily) in combination with Metformin (500 mg orally, twice daily for 2 weeks, then 850 mg orally,twice daily) in patients with unresectable Stage IIIC and Stage IV melanoma. Phase II will evaluate the clinical activity of the combined Vemurafenib/Metformin regimen. The safety profile of this combined Vemurafenib/Metformin regimen will be monitored during both phases. The treatment period consists of 28-day cycles until progression or unacceptable toxicity occurs. |

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. 7. 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; 8. 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; 9. Before study entry, written informed consent must be obtained from the patient prior to performing any study-related procedures. Exclusion Criteria: 1. Prior treatment with Vemurafenib; 2. Known hypersensitivity to Metformin or any of its components; 3. Previous progression of melanoma while on Metformin; 4. 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; 5. Pregnant, breast-feeding, or refusing double barrier contraception, oral contraceptives, or avoidance of pregnancy measures; 6. Have any other uncontrolled infection or medical condition that could interfere with the conduct of the study |
