FDA Approves Opsynvi (macitentan and tadalafil) for Adults with Pulmonary Arterial Hypertension

Johnson & Johnson announced that the U.S. Food and Drug Administration (FDA) has approved Opsynvi® – a single-tablet combination of macitentan, an endothelin receptor antagonist (ERA), and tadalafil, a phosphodiesterase 5 (PDE5) inhibitor – for the chronic treatment of adults with pulmonary arterial hypertension (PAH, World Health Organization [WHO] Group I) and WHO functional class (FC) IIIII. Opsynvi® may be used in patients with PAH who are treatment-naïve or who are already on an ERA, PDE5 inhibitor or both. Opsynvi® may be used in patients who are currently treated concomitantly with stable doses of macitentan 10mg and tadalafil 40mg (20mg x 2) as separate tablets.

With the approval, Johnson & Johnson now offers a PAH portfolio addressing all three foundational and guideline-recommended pathways – nitric oxide, endothelin, and prostacyclin. PAH is a rare, progressive, and life-threatening blood vessel disorder characterized by the constriction of small pulmonary arteries and elevated blood pressure in the pulmonary circulation that eventually leads to right heart failure. An estimated 500 to 1,000 new cases of PAH are diagnosed each year in the U.S., classifying the disease as a rare condition.

The 2022 European Society of Cardiology (ESC)/European Respiratory Society (ERS) clinical guidelines recommend initial combination therapy of an ERA and a PDE5 inhibitor for patients with idiopathic PAH, heritable drug-associated PAH, or PAH-associated with connective tissue disease without cardiopulmonary comorbidities at low or intermediate risk.

Individually, macitentan reduces the risk of clinical worsening events and hospitalization, and tadalafil improves exercise ability.
