a phase i, multicenter, open-label, dose-escalation study to assess the safety of lenalidomide in patients with advanced adult t-cell leukemia-lymphoma and peripheral t-cell lymphomaperipheral t-cell lymphoma

Conditions: Adult T-cell Leukemia-Lymphoma; Peripheral T-cell Lymphoma

Summary: to determine the maximum tolerated dose of lenalidomide in patients with adult t-cell leukemia-lymphoma (atl) and peripheral t-cell lymphoma (ptcl) who have previously received therapy for atl and ptcl
