Trial Description


MEK113583 is a Phase II open-label, multi-site study to investigate the objective response rate, safety, and pharmacokinetics of GSK1120212 in subjects with BRAF mutation-positive melanoma who were previously treated with or without a BRAF inhibitor. GSK1120212 is a potent and highly selective inhibitor of MEK activation and kinase activity.

Eligibility Criteria

Inclusion Criteria:

  • Metastatic cutaneous melanoma that was previously treated with: (Cohort A) a BRAF inhibitor either with or without other prior therapy. (Cohort B) at least 1 prior chemotherapy or immunotherapy, without treatment with a BRAF inhibitor.
  • Documented positive BRAF mutation (V600E, V600K, or V600D).
  • Subjects must provide archived tumor tissue or undergo fresh tumor biopsy prior to enrollment.
  • The subject must have a radiographically measurable tumor.
  • The subject is able to carry out daily life activities without significant difficulty (ECOG performance status score of 0 or 1).
  • Able to swallow and retain oral medication.
  • Sexually active subjects must use acceptable methods of contraception during the course of the study.
  • Adequate organ system function and blood cell counts.

Exclusion Criteria:

  • The subject has had major surgery or received certain types of cancer therapy within 21 days before starting the study.
  • Previous treatment with a MEK inhibitor.
  • Current use of a prohibited medication listed in the protocol.
  • Uncontrolled glaucoma.
  • Brain metastasis, unless previously treated with surgery or stereotactic radiosurgery, and the disease has been stable for at least 2 months prior to enrollment.
