Frequently asked questions about REGN7544

What is REGN7544 used for?

REGN7544 is an investigational small molecule being studied for sepsis-induced hypotension and postural orthostatic tachycardia syndrome (POTS), as well as in healthy volunteers. It is a natriuretic peptide receptor 1 (NPR1) antagonist. The drug is being developed by Regeneron Pharmaceuticals and is currently in clinical trials.

What does REGN7544 target?

REGN7544 targets natriuretic peptide receptor 1 (NPR1). As an NPR1 antagonist, it is being studied for its potential effects on conditions involving blood pressure regulation, including sepsis-induced hypotension and postural orthostatic tachycardia syndrome (POTS).

Who makes REGN7544?

REGN7544 is being developed by Regeneron Pharmaceuticals, Inc., a biopharmaceutical company traded on NASDAQ under the ticker REGN. The company is conducting clinical trials to evaluate the safety and efficacy of this investigational small molecule in multiple patient populations.

What phase is REGN7544 in?

REGN7544 has completed Phase 1 and Phase 2 clinical trials. A Phase 1 study in healthy volunteers and Phase 2 studies in patients with postural orthostatic tachycardia syndrome (POTS) and sepsis-induced hypotension have all been completed. The drug remains investigational and is not yet approved.

What clinical trials is REGN7544 in?

REGN7544 has been studied in three completed clinical trials: NCT05970718, a Phase 1 safety study in healthy volunteers; NCT06593600, a Phase 2 study in patients with postural orthostatic tachycardia syndrome (POTS); and NCT06608901, a Phase 2 study in patients with sepsis-induced hypotension.

Is REGN7544 the same as a natriuretic peptide receptor antagonist?

Yes, REGN7544 is a natriuretic peptide receptor 1 (NPR1) antagonist. This mechanism is being investigated for its potential to modulate blood pressure in conditions such as sepsis-induced hypotension and postural orthostatic tachycardia syndrome (POTS).
