Brief Summary: 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.
Detailed Description: Subjects entering this study will enter from the double-blind Study PB1046-PT-CL-0004. The starting dose level of pemziviptadil (PB1046) for all subjects in this parent study was a sub-therapeutic or minimally effective dose (MED) of 0.2 mg/kg, administered by SC injection.

Subjects were randomized into the MED) Group or a dose-titration group. In the dose-titration group, individual subjects were titrated up to their maximum tolerated dose (MTD) in a blinded fashion, with the objective of titrating subjects up to a dose of at least 1.2 mg/kg or higher in the MTD Group, while subjects in the MED Group remained at the MED level of 0.2 mg/kg, and underwent "sham dose-titration" to maintain the blind.

Subjects entering the 0006 trial prior to implementation of this protocol amendment will remain blinded until such time that open label dosing will not unblind the 0004 study.
