This study evaluates the drugs BKM120 and Vemurafenib (PLX4032) together in patients with unresectable advanced melanoma (skin cancer) carrying a BRAF V600E or V600K mutation. It included patients over 18 with Stage III-IV, BRAF-positive, measurable disease. It was a Phase 1/Phase 2 study and has been completed.

* 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
