About this study

Official title: An Open-label Extension Study of Oral Treprostinil in Subjects With Pulmonary Hypertension (PH) Associated With Heart Failure With Preserved Ejection Fraction (HFpEF) - A Long-term Follow-up to Study TDE-HF-301

This was an open-label study to evaluate the safety of continued therapy with oral treprostinil in subjects who completed Study TDE-HF-301. This study provided long-term, open-label data regarding the effect of continued long-term oral treprostinil therapy for the treatment of pulmonary hypertension (PH) associated with heart failure with preserved ejection fraction (HFpEF). Subject visits occurred at Baseline, Weeks 6, 12, 18, 24, and every 12 weeks thereafter until either oral treprostinil was commercially available to treat PH associated with HFpEF or the study was discontinued by the Sponsor.

The Sponsor terminated Studies TDE-HF-301 and TDE-HF-302 on 14 October 2019 due to slow enrollment. Safety data from the final subject in Study TDE-HF-302 were recorded on 02 March 2020. Due to the lower than expected number of subjects enrolled, the planned secondary efficacy-related endpoints were not analyzed.

Read the detailed description

Study TDE-HF-302 was a multicenter, open-label study in subjects participating and completing all required visits for Study TDE-HF-301. This study assessed the long-term safety of oral treprostinil in subjects with PH associated with HFpEF.

Subjects received oral treprostinil as 0.125-, 0.25-, 1-, and 2.5-mg sustained-release tablets. For subjects who were randomly allocated to receive oral treprostinil in Study TDE-HF-301, the initial dose of oral treprostinil was the same as the final dose in Study TDE-HF-301. Subjects randomly allocated to receive placebo in Study TDE-HF-301 were administered the initial dose of oral treprostinil at 0.125 mg 3 times daily (TID). Dose increases could occur in 0.125-mg increments every 72 hours at the discretion of the Investigator up to 6 mg TID, the maximum allowable dose determined by the Data Monitoring Committee during Study TDE-HF-301. Doses of study drug were to be increased in the absence of dose-limiting drug-related adverse events (AEs) to ensure that each subject received the optimal dose throughout the study. Subjects returned for visits at Weeks 6, 12, 18, and 24, and every 12 weeks thereafter. Subjects who terminated the study early were asked to return to the study center for a final evaluation.

Safety assessments consisted of AEs, clinical laboratory parameters, and clinical assessment of heart failure signs and symptoms.

Due to the lower than expected number of subjects enrolled, the planned secondary efficacy-related endpoints were not analyzed.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Long-term Safety of Oral Treprostinil in Subjects With PH Associated With HFpEF for Subjects Who Completed Study TDE-HF-301

    The primary objective of this study was to evaluate the long-term safety of oral treprostinil in subjects with PH associated with HFpEF for subjects who completed Study TDE-HF-301. The number of subjects with adverse events during the study is reported as the primary outcome measure, which was the only outcome measurement reported for this Sponsor-terminated study.

    Measured: Baseline through study completion, up to approximately 25 months

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Oral treprostinil in people with Pulmonary Hypertension Associated With HFpEF, run by United Therapeutics at 82 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 22 Oct 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 82 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 22 Oct 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Long-term Safety of Oral Treprostinil in Subjects With PH Associated With HFpEF for Subjects Who Completed Study TDE-HF-301 (time frame: Baseline through study completion, up to approximately 25 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Oct 2020.
