Eligibility Criteria:
Inclusion Criteria:~* Signed and dated Informed Consent Form (ICF).~* Participant remained in the main study (SERENADE/AC-055G202, NCT03153111) for: a) 52 weeks after randomization if entered this Open-label (OL) extension study prior to protocol Version 4, b) At least 24 weeks after randomization if entering this OL extension study under protocol Version 4~* A woman of childbearing potential is eligible only if: (1) Negative pre-treatment serum pregnancy test; (2) Agreement to undertake monthly pregnancy tests from the enrollment visit up to at least 30 days after study treatment discontinuation; and (2) Agreement to use reliable contraception from at least 30 days prior to the enrollment visit up to at least 30 days after study treatment discontinuation.~Exclusion Criteria:~* Premature discontinuation of study treatment in the main study (SERENADE/AC-055G202, NCT03153111) due to an adverse event related to: (1) Edema or fluid retention; (2) Worsening of heart failure; (3) Liver aminotransferase elevation; and (4) Study treatment, based on investigators' discretion~* Liver aminotransferase elevations, at the enrollment visit, fulfilling the following criteria: (1) Alanine amino transferase (ALT) / aspartate aminotransferase (AST) greater than or equal to (\>=) 8 \* the upper limit of normal (ULN); (2) ALT/AST \>= 3 \* ULN and associated clinical symptoms of liver injury, for example: nausea, vomiting, fever, abdominal pain, jaundice, unusual lethargy or fatigue, flu-like syndrome (arthralgia, myalgia, fever); and (3) ALT/AST \>= 3 \* ULN and associated increase in total bilirubin to \>= 2 \* ULN~* Treatment with the following forbidden medications within 1 month prior to the enrollment visit: (1) Treatments that may interfere with the assessment of efficacy (that is, endothelin receptor antagonists, prostanoids, phosphodiesterase-5 inhibitors, guanylate cyclase stimulators); (2) Strong cytochrome P-450 3A4 (CYP3A4) inducers such as rifabutin, rifampin, rifampicin, rifapentin, carbamazepine, phenobarbital, phenytoin, or St. John's wort; (3) Strong CYP3A4 inhibitors such as ketoconazole, itraconazole, voriconazole, clarithromycin, telithromycin, nefazodone, ritonavir, and saquinavir or a moderate dual CYP3A4/CYP2C9 inhibitor (for example, fluconazole or amiodarone) or co-administration of a combination of moderate CYP3A4 (for example, ciprofloxacin, cyclosporine, diltiazem, erythromycin, verapamil) and moderate CYP2C9 inhibitors (for example, miconazole, piperine), in the 1-month period prior to baseline. This will not necessarily apply to participants who are already well-managed on such an ongoing combination; and (4) any other investigational treatment~* Pregnant, planning to be become pregnant or lactating.~* Any known factor or disease that might interfere with treatment compliance, study conduct, or interpretation of the results, such as drug or alcohol dependence or psychiatric disease.~* Known hypersensitivity to macitentan or drugs of the same class, or any of the study drug excipients (for example, soy lecithin, lactose)
