Conducted under a Special Protocol Assessment (SPA) agreement with the U.S. Food and Drug Administration (FDA), Spectrum’s pivotal, registrational Phase 2 BELIEF trial is evaluating intravenous belinostat as monotherapy for relapsed or refractory peripheral T-cell lymphoma (PTCL), an indication for which this drug candidate has been granted Orphan Drug and Fast Track designations by the FDA. The BELIEF trial is an open-label, multicenter, single arm efficacy and safety study in patients with relapsed or refractory PTCL, who have failed at least one prior systemic therapy. The primary endpoint of the trial is centrally reviewed objective overall response rate (ORR). The trial included approximately 100 clinical centers globally, with completion of patient enrollment announced in September 2011.About Spectrum Pharmaceuticals, Inc.
