Study Overview

Brief Summary

This study evaluates the effects of VI-0106 (an extended-release formulation of tacrolimus) in participants with pulmonary arterial hypertension (PAH) who continue to have functional limitations despite being on optimized background PAH therapy. Participants will be randomly assigned with equal chance to receive either VI-0106 or placebo in a double-blind fashion to assess whether VI-0106 improves outcomes in this population.
