Frequently asked questions about REGN7544

What is REGN7544?

REGN7544 is an investigational small molecule developed by Regeneron Pharmaceuticals, Inc. for cardiovascular conditions. It is being studied in adults for Postural Orthostatic Tachycardia Syndrome (POTS) and sepsis-induced hypotension. REGN7544 is in Phase 2 clinical development and has not been approved by the FDA.

What is REGN7544 used for in POTS?

REGN7544 is being studied as a treatment for Postural Orthostatic Tachycardia Syndrome (POTS) in adults. A Phase 2 trial evaluated it in patients with POTS in the United States and Canada. REGN7544 remains investigational and is not approved for POTS or any other indication.

What does REGN7544 target?

REGN7544 targets natriuretic peptide receptor 1, also known as NPR1. NPR1 is a protein receptor, and REGN7544 is described as an NPR1 antagonist. By acting on this receptor, the small molecule is designed to modulate natriuretic peptide signaling in cardiovascular and hemodynamic conditions.

Who makes REGN7544?

REGN7544 is developed by Regeneron Pharmaceuticals, Inc., which trades on the Nasdaq under the ticker REGN. Regeneron is the sponsor of the clinical trials studying REGN7544 in Postural Orthostatic Tachycardia Syndrome and sepsis-induced hypotension.

What phase is REGN7544 in?

REGN7544 is in Phase 2 clinical development. It is an investigational small molecule and has not been approved by the FDA. Regeneron has completed Phase 2 trials in sepsis-induced hypotension and in Postural Orthostatic Tachycardia Syndrome, and no active trials are currently listed.

What clinical trials is REGN7544 in?

REGN7544 has been studied in two completed Phase 2 trials. NCT06608901 evaluated REGN7544 in adults with sepsis-induced hypotension across the United States and France, enrolling 76 patients. NCT06593600 studied an NPR1 antagonist in adults with Postural Orthostatic Tachycardia Syndrome in the United States and Canada, enrolling 82 patients.
