The session will be held in Room S103D (McCormick Place Convention Center) on Nov 17, 2024, from 3:30 PM to 4:45 PM.

The following poster presentations will be moderated:

• “Efficacy and safety of aprocitentan in patients with resistant hypertension receiving at least 4 antihypertensive medications including beta (β) blockers”, Weber M, et al. Zone 1, Moderated Digital Poster 1, Nov 17, 2024, 03:25 PM - 03:30 PM.

In addition, the following two abstracts on aprocitentan were among the best abstracts presented at AHA’s Hypertension Scientific Sessions Specialty Conference in September 2024. To honor the top-scoring abstracts, they have been selected to be re-presented as poster presentations at the annual Scientific Sessions, Science & Technology Hall, South Building, Level 3, Nov 17, 2024, from 03:15 PM - 04:15 PM:

• “A major effect of aprocitentan on albuminuria in patients with resistant hypertension”, Weber M, et al.

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. On June 27, 2024, the European Commission granted market authorization for JERAYGO™ (aprocitentan).
