NCT01588405
First received: January 6, 2012
Last updated: April 4, 2014

  Purpose

This multi-center, open-label study will assess the tolerability and safety of transitioning subjects with stable Pulmonary Arterial Hypertension (PAH) from continuous intravenous (IV) or subcutaneous (SC) Remodulin infusion to oral treprostinil (UT-15C sustained release (SR) tablets).

This study will consist of an in-hospital transition phase, dose optimization/evaluation phase, and follow up phase.

Primary Outcome Measures:
  • Successful transition from parenteral Remodulin to UT-15C [ Time Frame: Up to 24 weeks; then throughout follow-up phase until study completion ] [ Designated as safety issue: Yes ]
    TO assess the tolerability and safety of transitioning subjects from Remodulin to UT-15C SR in four weeks or less.


Secondary Outcome Measures:
  • Six-minute walk distance [ Time Frame: Baseline, Weeks 0, 1, 2, 4, 8, 12, 20 and 24; then every 3 months during follow-up phase until study completion ] [ Designated as safety issue: No ]
  • Borg dyspnea score [ Time Frame: Baseline, Weeks 0, 1, 2, 4, 8, 12, 20 and 24; then every 3 months during follow-up phase until study completion ] [ Designated as safety issue: Yes ]
  • Combined walk distance / Borg dyspnea score [ Time Frame: Baseline, Weeks 0, 1, 2, 4, 8, 12, 20 and 24; then every 3 months during follow-up phase until study completion ] [ Designated as safety issue: Yes ]
  • Quality of life, assessed by the Cambridge Pulmonary Hypertension Outcome Review questionnaire & Treatment Satisfaction Questionnaire of Medication [ Time Frame: Baseline, Weeks 12 and 24; then every 3 months during follow-up phase until study completion ] [ Designated as safety issue: No ]
  • WHO functional class [ Time Frame: Baseline, Weeks 4, 8, 12, 20 and 24; then every 3 months during follow-up phase until study completion ] [ Designated as safety issue: Yes ]
  • Dyspnea-fatigue index [ Time Frame: Baseline, Weeks 4, 8, 12, 20 and 24; then every 3 months during follow-up phase until study completion ] [ Designated as safety issue: Yes ]
  • Symptoms of PAH [ Time Frame: Baseline, Weeks 0, 1, 2, 4, 8, 12, 20 and 24; then every 3 months during follow-up phase until study completion ] [ Designated as safety issue: Yes ]
  • Pharmacokinetics [ Time Frame: Baseline and Week 24 ] [ Designated as safety issue: No ]
    Blood samples to be drawn from each subject at time 0 and times 2, 4, 5, 6, 8 and 12 hours after time 0 for a total of 7 samples.

  • Hemodynamics [ Time Frame: Screening and Week 24 ] [ Designated as safety issue: No ]
  • Safety [ Time Frame: up to 24 weeks; then ongoing throughout follow-up phase until study completion ] [ Designated as safety issue: Yes ]
    i.e., adverse events, clinical laboratory parameters, vital signs, echocardiograms, electrocardiograms


Estimated Enrollment: 30
Study Start Date: April 2012
Estimated Study Completion Date: December 2014
Estimated Primary Completion Date: July 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: UT-15C SR Drug: UT-15C SR
Subjects will transition in the hospital from Remodulin to UT-15C SR within 5 days of the start of the transition. The dose of Remodulin will be decreased as the dose of UT-15C SR is increased over the 5 days. Once subjects have been transitioned from Remodulin, the dose of UT-15C SR will continue to be modified / titrated to the appropriate optimal dose for that subject throughout the rest of the study.
