The goal of this clinical research study is to find the highest tolerable dose of the combination of ZelborafTM (vemurafenib) with Nexavar® (sorafenib) or Xalkori® (crizotinib) that can be given to patients with advanced cancer. The safety of these drugs will also be studied.

Vemurafenib is designed to block a protein called BRAFV600E inside the cancer cells, which is involved in cancer cell growth.

Sorafenib is designed to block the function of important proteins in and outside of cancer cells. These proteins are involved in cancer cells growth and new blood vessel development.

Crizotinib is designed to block certain abnormal genes found in cancer cells. This may cause the cancer cells to die.

Intervention Model: Single Group Assignment
Masking: Open Label

Primary Outcome Measures:
  • Maximum Tolerated Dose (MTD) of Vemurafenib and Sorafenib [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
    If more than 33% of enrolled at any particular dose level develop dose limiting toxicity (DLT), treatment will continue at dose level immediately below. If not more than 33% of cohort develop DLT, this cohort will be considered the MTD.

Secondary Outcome Measures:
  • Tumor Response [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
    Tumor response defined as one or more of the following: (1) stable disease for more than or equal to 4 months, (2) decrease in measurable tumor (sentinel lesions) by more than or equal to 20% by RECIST criteria, (3) decrease in tumor markers by more than or equal to 25% (for example, a >/= 25% decrease in CA125 for patients with ovarian cancer), or (4) a partial response according to the Choi criteria, i.e., decrease in size by 10% or more, or a decrease in the tumor density, as measured by Hounsfield units (HU), by more than or equal to 15%.

Estimated Enrollment: 183
Study Start Date: February 2012
Estimated Primary Completion Date: February 2016 (Final data collection date for primary outcome measure)

Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Patients with advanced or metastatic cancers and BRAF mutations that are refractory to standard therapy, relapsed after standard therapy, or who have no standard therapy available that improves survival by at least three months. Patients with BRAF mutation in cell free DNA (tested in CLIA lab) are also eligible.
  2. Patients must be >/= 3 weeks beyond treatment with a cytotoxic chemotherapy regimen, or therapeutic radiation, or major surgery. Patients may have received palliative localized radiation immediately before or during treatment provided that radiation is not delivered to the only site of disease being treated under this protocol. For biologic/targeted agents patients must be >/= 5 half-lives or >/= 3 weeks from the last dose (whichever comes first). Patients previously treated with vemurafenib monotherapy do not have to stop medication before they start on the protocol.
  3. ECOG performance status </= 2
  4. Patients must be >/= 18 years of age.
  5. Patients must have adequate organ and marrow function defined as: absolute neutrophil count (ANC) >/= 1,000/mL, platelets >/=75,000/mL; creatinine </= 2 X ULN; total bilirubin </= 2 X ULN; ALT (SGPT) and/or AST (SGOT) </= 5 X ULN Exception for patients with liver metastasis: total bilirubin </= 3 x ULN; ALT (SGPT) </= 8 X ULN.
  6. Dermatology evaluation with excision of any suspicious lesions prior to initiation of therapy.
  7. Women of childbearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, and for 30 days after the last dose.
  8. Women of childbearing potential must have a negative serum or urine pregnancy test within 2 weeks prior to initiation of therapy.
  9. Life expectancy >12 weeks in the opinion of the Investigator.
  10. Patients must be able to understand and be willing to sign a written informed consent document.
  11. Patient must be able to swallow pills.

Exclusion Criteria:

  1. Uncontrolled intercurrent illness, including, but not limited to, uncontrolled infection, uncontrolled asthma, need for hemodialysis, need for ventilatory support.
  2. Syndrome of congenital QTc prolongation or QTc >500 msec.
  3. Patients with clinically significant cardiovascular disease: history of cerebrovascular accident (CVA) within 6 months, myocardial infarction or unstable angina within 6 months, or unstable angina pectoris.
  4. Pregnant or lactating women.
  5. History of hypersensitivity to vemurafenib.
  6. History of hypersensitivity to sorafenib for vemurafenib/sorafenib arm.
  7. History of hypersensitivity to crizotinib for vemurafenib/crizotinib arm.
  8. History of hypersensitivity to any component of the formulation.
  9. Patients unwilling or unable to sign informed consent document.
  10. Patients using any of the following medications: mesoridazine, dronedarone, thioridazine, ziprasidone, levomethadyl, and saquinavir for vemurafenib/sorafenib arm.
