Safety, Tolerability, and Pharmacokinetics of Oral Treprostinil in Pediatric PAH Patients Aged 7 to 17 Years

PAH Clinical Trial

Official title: A Multicenter, Open-Label, 24-Week, Uncontrolled Study to Evaluate the Safety, Tolerability, and Pharmacokinetics of Oral Treprostinil Extended Release Tablets Following Transition From Remodulin or Inhaled Prostacyclin Therapy or as Add-on to Current PAH Therapy in De Novo Prostacyclin Pediatric Subjects Aged 7 to 17 Years With Pulmonary Arterial Hypertension

Status Completed

Clinical Trial Summary

This was a multi-center, open-label, safety, tolerability and pharmacokinetic study of oral treprostinil in pediatric subjects with stable PAH aged 7 to 17 years who were (1) transitioning from parenteral Remodulin therapy; (2) transitioning from inhaled prostacyclin therapy; or (3) not currently receiving prostacyclin therapy.

Clinical Trial Description

Study TDE-PH-206 was a multicenter, open-label study designed to investigate the safety, tolerability, and PK of oral treprostinil administered 3 times daily (TID) or 4 times daily (QID), at the discretion of the Investigator, with food in pediatric PAH subjects aged 7 to 17 years of age (1) transitioning from continuous IV/SC Remodulin, (2) transitioning from inhaled prostacyclin, or (3) as add-on to current PAH therapies in de novo prostacyclin subjects. Eligible subjects were assigned to a cohort based upon their background therapy. All subjects received oral treprostinil provided as 0.125, 0.25, 1, or 2.5 mg extended-release tablets. Subjects in Cohort 1 began the transition from IV/SC Remodulin in the hospital with a goal of complete transition to oral treprostinil within 5 days. The initial dose of oral treprostinil for Cohort 1 was calculated from the subject's dose of IV/SC Remodulin and weight. Subjects in Cohorts 2 and 3 were initiated on 0.125 mg TID or QID oral treprostinil with dose escalations possible every 24 hours in increments of 0.125 mg TID or QID at the discretion of the Investigator during the first 4 weeks, and in increments of either 0.125 mg or 0.25 mg every 24 hours thereafter. Cross titration occurred for Cohorts 1 and 2 such that doses of IV/SC Remodulin or inhaled prostacyclin were decreased as subjects were fully transitioned to oral treprostinil. ;
