Frequently asked questions about Ionis AGT-LRx

What is Ionis AGT-LRx?

Ionis AGT-LRx is an investigational small molecule developed by Ionis Pharmaceuticals, Inc. (ticker: IONS) for cardiovascular conditions. It has been studied in Phase 2 clinical trials for chronic heart failure with reduced ejection fraction and for hypertension in patients with uncontrolled blood pressure. It is not an approved therapy.

What is Ionis AGT-LRx used for?

Ionis AGT-LRx has been evaluated for two cardiovascular indications: chronic heart failure with reduced ejection fraction and hypertension in patients with uncontrolled blood pressure. Both uses were studied in Phase 2 clinical trials that have been completed. The drug remains investigational and is not approved for any indication.

Who makes Ionis AGT-LRx?

Ionis AGT-LRx is developed by Ionis Pharmaceuticals, Inc., which trades on the Nasdaq under the ticker IONS. Ionis is the sponsor of the Phase 2 clinical program evaluating the drug in chronic heart failure with reduced ejection fraction and in hypertension with uncontrolled blood pressure.

What phase is Ionis AGT-LRx in?

Ionis AGT-LRx is in Phase 2 development. Two Phase 2 trials have been completed, one in chronic heart failure with reduced ejection fraction and one in hypertensive patients with uncontrolled blood pressure. The drug is investigational and has not been approved by the FDA for any indication.

What clinical trials is Ionis AGT-LRx in?

Ionis AGT-LRx has been studied in two completed Phase 2 trials. NCT04836182 evaluated the drug in participants with chronic heart failure with reduced ejection fraction across the United States, Hungary, and Poland. NCT04714320 evaluated it in hypertensive participants with uncontrolled blood pressure in the United States and Canada.

Is Ionis AGT-LRx the same as IONIS-AGT-LRx?

Yes, Ionis AGT-LRx and IONIS-AGT-LRx refer to the same investigational drug. IONIS-AGT-LRx is the alternate name used in trial registrations and scientific literature, while Ionis AGT-LRx is the shorter form. Both names identify the same Phase 2 small molecule from Ionis Pharmaceuticals.
