Clinical Study to Compare the Efficacy and Safety of Macitentan and Tadalafil Monotherapies With the Corresponding Fixed-dose Combination Therapy in Subjects With Pulmonary Arterial Hypertension (PAH)
Study Purpose
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.

Study Type
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Pulmonary Arterial Hypertension (PAH) (WHO Group 1 PH) |
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.
