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).

About lucerastat
Lucerastat is Idorsia’s oral inhibitor of glucosylceramide synthase, offering a potential new treatment approach for all patients living with Fabry disease, irrespective of the mutation type of the GLA gene. In October 2021, the company reported that lucerastat 1000 mg b.i.d. did not meet the primary endpoint of reducing neuropathic pain during 6 months of treatment versus placebo. However, Lucerastat demonstrated a substantial reduction in levels of the Fabry disease biomarker plasma Gb3 during the treatment period, with a decrease of approximately 50% observed in plasma Gb3 in the lucerastat treatment group compared to an increase of 12% in the placebo group. Furthermore, results suggested a treatment effect on kidney function. Lucerastat was well tolerated. Analysis of the ongoing open-label extension (OLE) of the Phase 3 study corroborated the long-term effect on plasma Gb3 levels and a potential positive long-term effect on kidney function. The analysis also showed a safety and tolerability profile consistent with that observed during the 6-month randomized treatment period. The company is conducting a kidney biopsy substudy within a subset of patients currently participating in the OLE study in order to steer further development in Fabry disease. In parallel, Idorsia is working with regulatory authorities to design the next Phase 3 study to evaluate the effect of lucerastat on renal function.
