Summary

This phase II study in 20 patients with BRAFV600E mutant, unresectable stage III/IV melanoma is designed to explore the mechanisms by which tumors acquire resistance to the combination of a BRAF inhibitor (dabrafenib) and MEK inhibitor (trametinib). Tissue will be collected at baseline and at progression.If a subject is removed from the study for one of a variety of reasons including, but not limited to, an inability to tolerate the combination of dabrafenib and trametinib, a need to receive other therapy or completion of 3-years of study treatment without progression, and the subject later receives, as part of his/her standard of care, the combination of dabrafenib and trametinib and progresses on the standard of care regimen, then the subject may be contacted by the treating physician to be put back on to the LCCC 1128 protocol and have a progression biopsy at this progression time point. Markers of resistance will be explored by performing near kinome-wide profiling on tumor samples, and in patients who co-enroll in institutional protocol LCCC1108, by sequencing tumors using NextGen DNA sequencing technology. Overall response rate and duration to this combination will also be assessed.

Conditions

  • Stage III Melanoma
  • Stage IV Melanoma
  • Unresectable Melanoma
  • BRAF Mutant Melanoma

Interventions

DRUG

BRAF inhibitor dabrafenib and MEK inhibitor trametinib

Patients will receive the BRAF inhibitor dabrafenib and MEK inhibitor trametinib orally at the RP2D determined in the Phase I/II study (BRF113220): trametinib 2mg QD and dabrafenib 150 mg BID on a continuous basis. A cycle will be defined as 3 weeks in duration. Cycles will be repeated until disease progression (clinical or radiological). Patients may remain on treatment after progression (at the discretion of the investigator) as long as they are still experiencing clinical benefit.
