Summary
Background: Nowadays, there is no consensual and effective treatment in metastatic uveal melanoma (MUM). Numerous preclinical data (for example, 75% of MUM express c-kit) suggest that imatinib mesylate (IM) may be a potential treatment of UMM. Methods: The primary objective of this phase II trial was to determine the non-progression rate at 3 months for patients receiving IM at dose of 400 mg twice per day orally. The study was based on a Simon’s optimal design, which allows entry a total of 29 patients, if at least two non-progressions among ten first patients were observed. Result: Thirteen patients including ten assessable patients were enrolled in 12 months. No objective response and only one stable disease with duration of 5 months were noted. Five and one out of 13 enrolled patients experienced grade 3 and grade 4 toxicities, respectively. The most common severe adverse events were abdominal pain. The overall survival was 10.8 months. Conclusions: Despite promising preclinical data, IM is an inactive single agent in MUM. This phase II clinical trial has been stopped at the first step.
