Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
Treatment: Drugs - Selexipag
Treatment: Drugs - Placebo

Experimental: Selexipag DB - During the double blind treatment period, participants in this group will receive selexipag. Each participant will start with one oral tablet of selexipag 200 µg in the evening of Day 1 and will continue with 200 µg twice daily (b.i.d.) on Day 2. If this dose is well-tolerated, selexipag is up-titrated with weekly increments of 200 µg until reaching the individual maximal tolerated dose (iMTD) in the range of 200 to 1600 µg b.i.d. The up-titration period up to Week 12 is followed by a stable maintenance treatment period from Week 12 to Week 26, at the iMTD. After Week 26, further up-titration can be allowed (but not above 1600 µg b.i.d.).

Placebo comparator: Placebo DB - During the double-blind treatment period, participants in this group will receive the oral matching placebo, twice daily. A (mock) up-titration scheme will be followed.

Experimental: Selexipag OL - All participants who completed the double-blind treatment period, whether they received placebo or selexipag during the double-blind period, will receive selexipag during the open-label extension period, using the same up-titration schedule as in the double-blind period.


Treatment: Drugs: Selexipag
oral tablets containing 200 µg of selexipag. Depending on the iMTD, participants will receive 1 to 8 tablets at each administration

Treatment: Drugs: Placebo
Oral tablets without active compound

* Treatment with prostacyclin (epoprostenol), prostacyclin analogs (i.e., treprostinil, iloprost, beraprost) or prostacyclin receptor agonists (i.e., selexipag) within 90 days prior to randomization (visit 2) except those given at vasodilator testing during RHC
* Change in dose or initiation of new diuretics and/or calcium channel blockers within 1 week prior to baseline RHC (and LHC, if needed)

Summary
Brief summary
Selexipag is available in many countries for the treatment of pulmonary arterial hypertension (PAH). Due to the similarities between PAH and chronic thromboembolic pulmonary hypertension (CTEPH) and the observed efficacy of other PAH medicines in CTEPH, it is believed that selexipag could benefit to patients with CTEPH. This study aims to assess the efficacy and safety of selexipag in participants with inoperable or persistent/recurrent CTEPH.
