Driver: Expansion of Activin Signalling Inhibitors Beyond Conventional Vasodilator Therapy
The expansion of activin signalling inhibitors is reshaping pulmonary arterial hypertension treatment by addressing vascular remodelling rather than relying exclusively on vasodilation. Conventional endothelin receptor antagonists, phosphodiesterase inhibitors and prostacyclin therapies improve pulmonary blood flow but may not adequately control the cellular proliferation driving disease progression. Merck’s Winrevair introduced a differentiated mechanism that rebalances signalling within the transforming growth factor beta superfamily. Its use alongside background therapy supports improvements in exercise capacity and functional status while reducing clinical-worsening risk, strengthening demand for multimodal treatment among intermediate-risk and high-risk patients.
Commercial adoption of activin-targeted therapy is expected to increase treatment value per patient and encourage earlier escalation beyond traditional dual or triple vasodilator combinations. The mechanism is also stimulating pipeline investment, including GSK’s HS235, which is being developed with enhanced selectivity and the potential for improved tolerability. Competition will increasingly focus on bleeding risk, haemoglobin elevation, dosing convenience, patient-selection criteria and compatibility with established therapies. Successful geographic expansion, reimbursement and real-world evidence could establish activin signalling inhibitors as a foundational fourth therapeutic pathway, supporting sustained market growth and changing treatment sequencing across specialized PAH centres.
Restraint Impact Analysis
| Restraint | Drag on Market Growth (%) | Primary Impact Area | Impacted Use Case | Strategic Impact |
Persistent Diagnostic Delay and Limited Access to Right-Heart Catheterization | 16.3% | Patient identification, treatment initiation and specialist referral | Patients with unexplained dyspnoea initially managed for asthma, chronic lung disease or general heart failure without PAH confirmation | Reduces the diagnosed and treatment-eligible population, delays initiation of PAH-specific therapy and limits lifetime treatment duration |
High Lifetime Cost of Multidrug and Disease-Modifying Treatment | 14.7% | Reimbursement, formulary access and therapy escalation | Patients requiring dual or triple background therapy combined with premium activin-signalling or prostacyclin treatments | Increases payer scrutiny, prior-authorization requirements and treatment sequencing restrictions, particularly in cost-sensitive healthcare systems |
Safety Monitoring and Administration Burden Across Advanced Therapies | 12.1% | Treatment persistence, patient eligibility and adherence | Patients receiving parenteral prostacyclins, inhaled therapies or activin-signalling inhibitors requiring laboratory and clinical monitoring | Limits adoption among elderly and comorbid patients, increases specialist workload and may cause discontinuation or delayed escalation |

Restraint: Persistent Diagnostic Delay and Limited Access to Right-Heart Catheterization
Persistent diagnostic delay remains a major restraint because early PAH symptoms, including exertional breathlessness, fatigue, dizziness and chest discomfort, overlap with asthma, chronic obstructive pulmonary disease, interstitial lung disease and left-sided heart failure. Patients may undergo repeated consultations and non-definitive testing before referral to a pulmonary-hypertension specialist. Echocardiography supports initial screening but cannot independently confirm PAH. Definitive diagnosis requires right-heart catheterization to measure pulmonary pressures, pulmonary vascular resistance and cardiac output while excluding alternative forms of pulmonary hypertension. Limited catheterization capacity therefore slows accurate disease classification and treatment initiation.
Access challenges are particularly significant in rural areas, emerging economies and healthcare systems with few specialist centres, trained cardiologists or standardized referral pathways. Delayed confirmation allows vascular remodelling and right-ventricular dysfunction to progress, meaning patients may enter treatment at a higher functional class with poorer outcomes. Commercially, this reduces the diagnosed and treatment-eligible population, shortens lifetime therapy duration and limits the adoption of combination and disease-modifying treatments. Expanding specialist networks, standardized diagnostic algorithms, referral education, teleconsultation and catheterization capacity will be essential to convert suspected cases into confirmed patients and unlock underserved regional demand.
Pulmonary Arterial Hypertension Market Segment Analysis
The global pulmonary arterial hypertension market is segmented based on drug class, route of administration, distribution channel, and region.
Drug Class:The prostacyclin and prostacyclin analogs segment is dominating the pulmonary arterial hypertension market with a 35.17% share in 2024
The prostacyclin and prostacyclin analogs segment is dominating the market because these therapies remain the gold standard for patients with advanced or rapidly progressing disease, offering the most significant improvements in survival and quality of life. Prostacyclin is a potent vasodilator and inhibitor of platelet aggregation, directly countering the pathophysiology of PAH. The first approved therapy, epoprostenol (Flolan, Veletri), set the benchmark by demonstrating substantial survival benefits, even though it required continuous intravenous infusion with complex catheter systems.
Building on this, newer analogs such as treprostinil (Remodulin for IV/SC, Tyvaso for inhalation, and Tyvaso DPI for dry powder inhalation) have expanded administration options, making treatment more convenient and reducing infection risks associated with IV delivery. Similarly, iloprost (Ventavis) offers inhalation therapy for patients unable to tolerate systemic side effects, while selexipag (Uptravi), an oral prostacyclin receptor agonist, represents a breakthrough by providing prostacyclin pathway targeting in a patient-friendly tablet form. These advancements not only improve adherence but also expand use into earlier stages of the disease.
The clinical superiority of prostacyclin therapies in improving exercise capacity, hemodynamics, and long-term outcomes has ensured their central role in treatment guidelines worldwide. Moreover, the continued innovation in formulations, such as the approval of Tyvaso DPI in 2022, the first dry powder inhaler for PAH, has boosted adoption by improving ease of use. Because these drugs provide unmatched efficacy in reducing disease progression and mortality, especially in severe cases, the prostacyclin and prostacyclin analogs segment holds the largest share in the PAH market and continues to lead despite competition from ERAs, PDE-5 inhibitors, and newer therapies.

U.S. Pulmonary Arterial Hypertension Market Landscape
The U.S. pulmonary arterial hypertension market is characterized by concentrated specialist care, high therapy expenditure and rapid adoption of differentiated treatments. Approximately 45,000 patients were diagnosed and treated for PAH in the United States in 2025, although delayed referral and disease misclassification continue to restrict the addressable population. Treatment is increasingly guided by risk status and combines endothelin receptor antagonists, phosphodiesterase inhibitors, soluble guanylate cyclase stimulators and prostacyclin-pathway therapies. The introduction of Winrevair has expanded the market beyond conventional vasodilation toward activin-signalling modulation, supporting earlier escalation for patients inadequately controlled with background therapy.
Competition is led by Johnson & Johnson, United Therapeutics, Merck, Bayer and Liquidia, supported by specialty pharmacies and dedicated PAH treatment centres. Commercial differentiation increasingly depends on clinical-worsening reduction, administration convenience, monitoring requirements and payer access. In August 2026, the FDA accepted United Therapeutics’ NDA for once-daily oral ralinepag. Its 687-patient Phase III ADVANCE OUTCOMES study reported a 55% reduction in clinical-worsening risk versus placebo. Future expansion will depend on improved diagnosis, broader reimbursement for multidrug regimens and increased use of oral, inhaled and disease-modifying therapies.
Japan Pulmonary Arterial Hypertension Market Outlook
Japan’s pulmonary arterial hypertension market is characterized by centralized specialist care, government-supported rare-disease coverage and strong adoption of combination therapy. The national rare-disease database reports 4,682 certified PAH patients, although the treated population may be higher because certification data do not capture every diagnosed patient. Demand is concentrated in university hospitals and specialist cardiovascular centres with access to right-heart catheterization and advanced treatment monitoring. Established therapies include endothelin receptor antagonists, phosphodiesterase inhibitors, soluble guanylate cyclase stimulators and oral, inhaled or parenteral prostacyclin-pathway medicines. Domestic companies such as Nippon Shinyaku and Toray maintain important positions alongside multinational manufacturers.
The competitive outlook changed materially on June 24, 2025, when Japan approved Airwin, the local brand of sotatercept, for PAH. Its activin-signalling mechanism introduces a vascular-remodelling approach beyond conventional vasodilation and supports use alongside background therapy. Japanese clinical development included 46 PAH patients, strengthening locally relevant evidence for efficacy and safety assessment. Growth through 2026 and beyond will depend on specialist uptake, reimbursement positioning, laboratory-monitoring capacity and appropriate selection of patients with persistent intermediate or high risk despite combination therapy.
