Detailed Description
The phase 1 portion of this trial is a dose escalation study; the phase 2 portion is a single-stage, single arm prospective clinical trial. All patients will receive continuous doses of vemurafenib twice a day and BKM120 once a day.
In the phase 1 portion of the study, there will be a 7 day lead-in period to allow for single dose pharmacokinetic analysis of BKM120 alone. Cycle 1 (28 days) is the dose-limiting toxicity (DLT) period. During phase 1, vemurafenib and BKM120 doses will be escalated using a standard 3+3 dose escalation scheme with the goal of identifying the recommended phase 2 dose.
In the phase 2 portion of the study, patients will receive continuous doses of vemurafenib and BKM120 starting on day 1 of the first cycle. In the phase 2 portion of the study, patients will receive vemurafenib and BKM120 at the recommended phase 2 dose.

- Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, must use highly effective contraception during treatment for 3 months in total after study drug discontinuation. Highly effective contraception is defined as either: True abstinence-when this is in line with the preferred and usual lifestyle of the subject, periodic abstinence and withdrawal are not acceptable methods of contraception; Sterilization-have had surgical bilateral oophorectomy (with or without hysterectomy) or tubal ligation at least six weeks ago; Male partner sterilization-for female subjects, the vasectomised male partner should be the sole partner for that patient; Use of a combination of any two of the following barrier methods of contraception-condom or Occlusive cap with spermicidal foam/gel/film/cream/vaginal suppository
