Who can join

Age: 16 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• AJCC (2009) stage IIIC cutaneous melanoma rendered free of disease by surgical resection no greater than 90 days prior study enrollment. Patients with unknown primaries will be eligible for this trial. Patients with a history of resected stage I or II cutaneous melanoma who subsequently have their first disease recurrence meeting the criteria for stage IIIC disease will also be eligible for this trial.
• Patients must have clear margins after wide local excision. Patients with nodes that are palpable or detectable on radiologic imaging must have an adequate lymphadenectomy.
• Patients must be adequately recovered from surgery, radiation therapy, or any surgical complications prior to enrollment. In general, this means patients will be off antibiotics from wound infections and drains removed. However, if necessary, patients can be treated with a drain in place at the discretion of the PI if the 90 days window is about to expire.
• Histologic proof of melanoma reviewed and confirmed by MSKCC.
• A documented BRAFV600E or BRAFV600K mutation by genotyping or IHC [35]performed by a CLIA certified laboratory.
• Age ≥ 16 years old
• ECOG performance status = 0 or Karnofsky Performance Status equivalent
• The ability to swallow pills.
• Patients must have adequate organ and marrow function as defined below:
• Absolute neutrophil count ≥1.5 K/mcL Platelets ≥ 100 K/mcL Hemoglobin ≥ 9.0 g/dL Total bilirubin ≤ 1.5 X institutional upper limit of normal (ULN)
• ≤ 3.0 X institutional ULN if the patient has Gilbert's Syndrome AST (SGOT) and ALT (SGPT) ≤ 2.5 X institutional ULN Creatinine ≤ 1.5 X institutional ULN or creatinine clearance (calculated or measured) > 60 ml/min
• Women with child bearing potential and men with reproductive potential must be willing to practice acceptable methods of contraception.

You may not qualify if…

• Patients with a history of stage III melanoma (any primary melanoma with locoregional nodal/subcutaneous disease) treated with surgical resection who subsequently have disease recurrence meeting the criteria for stage IIIC disease.
• Prior therapy with ipilimumab, other BRAF inhibitors, or MEK inhibitors.
• Concurrent adjuvant immunotherapy, chemotherapy, or radiotherapy.
• Current use of a prohibited medication while on dabrafenib
• Presence of active gastrointestinal disease or other condition that will interfere significantly with the absorption of drugs.
• A history of known glucose-6-phosphate dehydrogenase (G6PD) deficiency.
• Pregnant women and lactating women.
• A concurrent second malignancy even if it does not require active therapy. Patients with indolent B-cell malignancies will not be eligible. Prior malignancy will be allowed as long as the patient is known to be free of disease for at least 3 years.
• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
• QTc interval > 500 msec unless a bundle branch block is also present.
