ABSTRACT: PURPOSE: Although durable responses can be achieved with tyrosine kinase inhibitors such as imatinib in melanomas harboring KIT mutations, the efficacy of alternative inhibitors after progression to imatinib and the activity of these agents on brain metastases are unknown. EXPERIMENTAL DESIGN: We conducted a phase II study of nilotinib 400 mg twice a day in two cohorts of patients with melanomas harboring KIT mutations or amplification: (A) those refractory or intolerant to a prior KIT inhibitor; and (B) those with brain metastases. The primary endpoint was 4-month disease control rate. Secondary endpoints included response rate, time-to-progression (TTP), and overall survival (OS). A Simon two-stage and a single-stage design was planned to assess for the primary endpoint in cohorts A and B, respectively. RESULTS: Twenty patients were enrolled and 19 treated (11 in cohort A; 8 in cohort B). Three patients on cohort A [27%; 95% confidence interval (CI), 8%-56%] and 1 on cohort B (12.5%; 90% CI, 0.6%-47%) achieved the primary endpoint. Two partial responses were observed in cohort A (18.2%; 90% CI, 3%-47%); none were observed in cohort B. The median TTP and OS was 3.3 (90% CI, 2.1-3.9 months) and 9.1 months (90% CI, 4.3-14.2 months), respectively, in all treated patients. CONCLUSIONS: Nilotinib may achieve disease control in patients with melanoma harboring KIT alterations and whose disease progressed after imatinib therapy. The efficacy of this agent in KIT-altered melanoma with brain metastasis is limited.

ABSTRACT: CONTEXT: Some melanomas arising from acral, mucosal, and chronically sun-damaged sites harbor activating mutations and amplification of the type III transmembrane receptor tyrosine kinase KIT. We explored the effects of KIT inhibition using imatinib mesylate in this molecular subset of disease. OBJECTIVE: To assess clinical effects of imatinib mesylate in patients with melanoma harboring KIT alterations. DESIGN, SETTING, AND PATIENTS: A single-group, open-label, phase 2 trial at 1 community and 5 academic oncology centers in the United States of 295 patients with melanoma screened for the presence of KIT mutations and amplification between April 23, 2007, and April 16, 2010. A total of 51 cases with such alterations were identified and 28 of these patients were treated who had advanced unresectable melanoma arising from acral, mucosal, and chronically sun-damaged sites. INTERVENTION: Imatinib mesylate, 400 mg orally twice daily. MAIN OUTCOME MEASURES: Radiographic response, with secondary end points including time to progression, overall survival, and correlation of molecular alterations and clinical response. RESULTS: Two complete responses lasting 94 (ongoing) and 95 weeks, 2 durable partial responses lasting 53 and 89 (ongoing) weeks, and 2 transient partial responses lasting 12 and 18 weeks among the 25 evaluable patients were observed. The overall durable response rate was 16% (95% confidence interval [CI], 2%-30%), with a median time to progression of 12 weeks (interquartile range [IQR], 6-18 weeks; 95% CI, 11-18 weeks), and a median overall survival of 46.3 weeks (IQR, 28 weeks-not achieved; 95% CI, 28 weeks-not achieved). Response rate was better in cases with mutations affecting recurrent hotspots or with a mutant to wild-type allelic ratio of more than 1 (40% vs 0%, P = .05), indicating positive selection for the mutated allele. CONCLUSIONS: Among patients with advanced melanoma harboring KIT alterations, treatment with imatinib mesylate results in significant clinical responses in a subset of patients. Responses may be limited to tumors harboring KIT alterations of proven functional relevance. Trial Registration clinicaltrials.gov Identifier: NCT00470470.
