The European Commission (EC) has approved Johnson and Johnson’s Yuvanci (macitentan + tadalafil) for the treatment of pulmonary arterial hypertension (PAH).
The approval marks Yuvanci as the only single-tablet combination therapy available for patients with PAH. PAH is a rare, progressive disorder in which patients have high blood pressure in the pulmonary arteries for no apparent reason. Current treatment for PAH involves first-line dual combination therapy with macitentan and tadalafil for patients without cardiopulmonary comorbidities. This currently consists of a multi-pill regimen.
“This can deeply impact their [PAH patients’] daily lives as they might struggle to maintain adherence to their treatment regimen,” said Dr. Tamara Werner-Kiechle, the Europe, Middle East, and Africa (EMEA) therapeutic area lead for neuroscience and cardiopulmonary drugs at Johnson & Johnson Innovative Medicine in a 30 September press release.
Johnson and Johnson has developed the Yuvanci as a substitution therapy for the long-term treatment of PAH in adults of the World Health Organization’s (WHO) Functional Class (FC) II to III. This includes patients with PAH that causes a slight limitation in physical activity, yet they are still comfortable at rest, and “patients with marked limitations to physical activity”, as per WHO. Patients will need to have already been treated with a two-pill combination of macitentan and tadalafil to be eligible for Yuvanci. Johnson and Johnson currently markets macitenan monotherapy under the brand name Opsumit, whilst Eli Lilly sells tadalafil as Cialis for PAH.
The approval is based on data from the Phase III A DUE study (NCT03904693), which also led to a positive recommendation for Yuvanci’s approval by the European Medicines Agency’s (EMA) Committee for Human Medicinal Products in July. The pharmaceutical giant presented data from the Phase III A DUE clinical study at the American College of Cardiology’s 72nd Annual Scientific Session. In the double-blind study, Yuvanci-treated patients showed significant improvements in the co-primary endpoints of pulmonary vascular resistance (PVR) and pulmonary haemodynamic improvement. Patients who took the combination therapy demonstrated a 44% decrease in PVR compared to a 22% decrease in the Adcirca monotherapy group.
Opsumit is an endothelin receptor antagonist that treats PAH by inhibiting pathways related to vasoconstriction, fibrosis and proliferation. Meanwhile, Cialis is a phosphodiesterase type-5 inhibitor that treats the disorder by increasing cGMP, leading to a relaxation of the pulmonary vascular smooth muscle cell and vasodilation of the pulmonary vascular bed.
