---|---|---|---|---|---|---|---|
KIT L576P | melanoma | predicted - sensitive | Imatinib | Case Reports/Case Series | Actionable | In a clinical case study, Gleevec (imatinib) treatment resulted in a 42% reduction of target lesions and an improvement of symptoms in a patient with metastasized labial melanoma harboring KIT L576P (PMID: 20372153). | 20372153 |
KIT L576P | melanoma | predicted - sensitive | Imatinib | Case Reports/Case Series | Actionable | In a Phase II trial, Gleevec (imatinib) treatment resulted in a durable objective response rate of 16% (4/25, 2 complete and 2 partial responses), a median time-to-progression of 12 weeks, and a median survival from treatment initiation of 46.3 weeks in patients with melanoma harboring KIT mutations, including 2 complete, 1 partial, 1 transient partial response, and 1 stable disease in patients harboring KIT L576P (n=7) (PMID: 21642685; NCT00470470). | 21642685 |
KIT L576P | melanoma | predicted - sensitive | Imatinib | Case Reports/Case Series | Actionable | In a Phase II trial, Gleevec (imatinib) treatment resulted in a best overall response rate of 53.8% (7/13, all partial responses) in patients with mucosal, acral, or chronically sun-damaged skin melanoma harboring KIT activating mutations in exons 11 (n=9), 13 (n=3), and 17 (n=1), including 3 partial responses and 1 with stable disease in patients with melanoma harboring KIT L576P (PMID: 23775962; NCT00424515). | 23775962 |
