About this study

This is a multi-center, Phase 2 Long-Term, Open Label Extension (OLE) Study to assess the safety and tolerability of pemziviptadil (PB1046) at an optimally titrated dose. This is a Long-Term, Open label Extension (OLE) Study for subjects with (PAH), having participated in double-blind Study PB1046-PT-CL-0004. The study will include adult subjects previously diagnosed with symptomatic PAH, who are receiving background clinician-directed therapy for PAH. During this period, subjects will continue to be followed for safety and tolerability, as well as for periodic efficacy, quality of life data and immunogenicity. The study will continue per the schedule of events until such time when pemziviptadil (PB1046) is able to be self-administered, becomes commercially available to the subjects in a particular country or region, or the sponsor terminates the study due to lack of efficacy, safety or other reasons.
