• Status: Terminated
• Trial end date: 2018-08-01
• Target enrollment: 0
• Participant gender: All

Summary

Ubenimex is being developed for the treatment of pulmonary arterial hypertension (PAH) (World Health Organization [WHO] Group 1) to improve exercise capacity and delay clinical worsening. This study is a Phase 2, open-label, multicenter, extension study to evaluate long-term safety and efficacy of ubenimex in patients with PAH (WHO Group 1) who complete Study EIG-UBX-001 (Study EIG-UBX-001 is a Phase 2, randomized, double-blind, placebo-controlled clinical trial) and meet the eligibility criteria for Study EIG-UBX-002. The primary objective for this study is:

• to obtain long-term safety and tolerability data for ubenimex (150 mg administered three times daily [TID]) in patients with PAH (WHO Group 1).

• Phase: Phase 2
• Accepts Healthy Volunteers?: No
