Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Combination therapy in pulmonary arterial hypertension (PAH) has been the subject of active investigation for more than a decade, with the benefit of targeting different pathways known to be involved in the pathogenesis of the disease. Adherence to prescribed therapy has an impact on clinical outcomes. Reducing the pill/tablet count and frequency has a major impact on patients' adherence to therapies and therefore the observed clinical outcomes. One way to simplify treatment is to use fixed-dose combination (FDC) products that combine multiple treatments targeting different pathways into a single tablet.

This study aims to demonstrate that the FDC of macitentan and tadalafil is more effective than therapy with 10 mg of macitentan alone or 40 mg of tadalafil alone. This phase 3 study will evaluate the efficacy and safety at 16 weeks of an FDC (macitentan 10 mg and tadalafil 40 mg) against these two PAH-approved therapies given as monotherapy to further confirm the added value of the FDC.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

PAH is characterized by a progressive increase in pulmonary arterial pressure (PAP) and in pulmonary vascular resistance (PVR) potentially leading to right heart failure and death. Current PAH-specific therapeutic options include treatments that target the three pathways (endothelin, nitric oxide, and prostacyclin pathways). While combination treatment is common, FDC pills or tablets that combine two or more PAH-specific therapies are not available, thereby requiring participants to take multiple pills/tablets daily. An FDC is an attractive option for PAH participants because it simplifies the treatment regimen by combining two therapies (which would otherwise involve a total of three tablets: one macitentan 10 mg tablet and two tadalafil 20 mg tablets) into a single tablet. Macitentan is an orally active, non-peptide, potent dual endothelin receptor A and B antagonist. Tadalafil is a selective inhibitor of phosphodiesterase type-5 (PDE-5), the enzyme responsible for the degradation of cyclic guanosine monophosphate (cGMP). This study comprises the following consecutive periods: Screening period (lasts up to 30 days), Double-blind treatment period (consists of the titration phase \[the first 2 weeks\] and the maintenance phase \[Week 3 through Week 16\]), Open-label treatment period, End-of-Treatment (EOT), Safety follow-up (S-FU) period, and End of Study (EOS). The total study duration for a participant will be up to 30 months. Study assessments like physical examinations, vital signs, right heart catheterization, 6-minute walk test will be performed. Safety will be assessed throughout the study.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

In total, approximately 170 subjects are planned to be randomized into study to receive either FDC macitentan/tadalafil or macitentan 10 mg or tadalafil 40 mg given once daily and will also receive matching placebos for two other study treatments. Treatment allocation will be stratified based on prior PAH therapy (i.e., treatment-naïve or treated by an Endothelin receptor antagonist or a Phosphodiesterase type-5 inhibitor as a monotherapy) at baseline. Sample size will be re-estimated at interim analysis if study is not terminated early for efficacy/futility up to sample size of 150-250. After completion of double-blind treatment period, subjects will continue study in an open-label treatment (OLT) period for 24 months, which may be prolonged beyond 24 months until macitentan and tadalafil are accessible at required doses, through other options according to local regulations. All assessments at end of double-blind treatment must be completed before subject enters OLT period.
