Notes to the editor

About aprocitentan
Aprocitentan is Idorsia’s once-daily, orally active, dual endothelin receptor antagonist, which inhibits the binding of ET-1 to ET_A and ET_B receptors. In May 2022, Idorsia announced positive top-line results of the Phase 3 PRECISION study with aprocitentan for the treatment of patients with resistant hypertension. Detailed results were published in The Lancet and presented as a Late-Breaking Science presentation during the American Heart Association (AHA) Scientific Sessions in November 2022. More details and commentary can be found in the dedicated press release and an investor webcast featuring Prof. Markus Schlaich, an investigator in PRECISION.

On March 19, 2024, aprocitentan was approved as TRYVIO in the US, with availability planned for H2 2024. On April 25, 2024, Idorsia received a positive opinion for aprocitentan (as JERAYGO™) from the Committee for Medicinal Products for Human Use (CHMP) as a treatment of resistant hypertension. A CHMP positive opinion is one of the final steps before marketing authorization can be granted by the European Commission; a final decision is expected approximately two months after publication of the CHMP opinion.
