Capmatinib, Ceritinib, Regorafenib, or Entrectinib in Treating Patients With BRAF/NRAS Wild-Type Stage III-IV Melanoma

PRIMARY OBJECTIVES:

I. To estimate the clinical activity of tyrosine kinase inhibitors matched to the
tumor-specific fusion kinase in patients with metastatic melanoma.

SECONDARY OBJECTIVES:

I. To estimate tumor stability in melanoma patients treated with kinase inhibitors matched to
the tumor-specific fusion kinase.

II. To estimate survival in melanoma patients treated with kinase inhibitors matched to the
tumor-specific fusion kinase.

III. To examine the safety and tolerability of kinase inhibitors in patients with melanoma
with a fusion kinase.

TERTIARY OBJECTIVES:

I. To explore molecular mechanisms of resistance for patients who progress on therapy.

OUTLINE: Patients are assigned to 1 of 4 arms.

ARM A: Patients with MET fusion receive capmatinib orally (PO) twice daily (BID) on day 1-28.
Courses repeat every 28 days in the absence of disease progression or unaccepted toxicity.

ARM B: Patients with ALK fusion receive ceritinib PO once daily (QD) on days 1-28. Courses
repeat every 28 days in the absence of disease progression or unaccepted toxicity.

ARM C: Patients with RET or BRAF fusion receive regorafenib PO QD on day 1-21. Courses repeat
every 28 days in the absence of disease progression or unaccepted toxicity.

ARM D: Patients with NTRK1, NTRK2, NTRK3, or ROS1 fusion receive entrectinib PO QD on days
1-28. Courses repeat every 28 days in the absence of disease progression or unaccepted
toxicity.

After completion of study treatment, patients are followed up within 30 days and then
periodically.
