Title:
Phase II, open-label, single-arm trial of imatinib mesylate in patients with metastatic melanoma harboring c-Kit mutation or amplification
Excerpt:
Forty-three patients with metastatic melanoma harboring c-Kit aberrations were enrolled on this phase II trial....The median progression-free survival (PFS) was 3.5 months, and the 6-month PFS rate was 36.6%. Rate of total disease control was 53.5%: 10 patients (23.3%; 95% CI, 10.2% to 36.4%) and 13 patients (30.2%; 95% CI, 16.0% to 44.4%) achieved partial response (PR) and stable disease (SD), respectively....Imatinib demonstrated significant activity in patients with metastatic melanoma harboring genetic c-Kit aberrations, with an overall response rate of 23.3%.

Title:
Imatinib for Melanomas Harboring Mutationally Activated or Amplified KIT Arising on Mucosal, Acral, and Chronically Sun-Damaged Skin
Excerpt:
The overall disease control rate was 50% but varied significantly by KIT mutation status (77% mutated v 18% amplified)...Imatinib can be effective when tumors harbor KIT mutations, but not if KIT is amplified.
