Frequently asked questions about ARRY-502

What is ARRY-502 used for?

ARRY-502 is an investigational oral small molecule that was studied for the treatment of persistent asthma. It was evaluated in a Phase 2 clinical trial in adults with asthma. ARRY-502 is not approved for any indication and remains in clinical development.

What does ARRY-502 target?

ARRY-502 targets PTGDR2, also known as the CRTh2 receptor. It acts as an antagonist at this receptor. By blocking PTGDR2, ARRY-502 is designed to interfere with CRTh2-mediated signaling pathways involved in allergic inflammation, which is relevant to asthma.

Who is developing ARRY-502?

ARRY-502 is being developed by Pfizer, Inc. (ticker: PFE). Pfizer is the company responsible for the clinical development of this oral CRTh2 antagonist for asthma.

What phase is ARRY-502 in?

ARRY-502 is in Phase 2 clinical development. It has completed one Phase 2 trial in patients with persistent asthma. The drug is investigational and has not been approved by the FDA for any indication.

What clinical trials is ARRY-502 in?

ARRY-502 has been studied in one completed Phase 2 clinical trial, NCT01561690, titled "A Study of ARRY-502 in Patients With Persistent Asthma." The trial enrolled 184 participants in the United States and was randomized, double-blind, and placebo-controlled.

Is ARRY-502 the same as a CRTh2 antagonist?

Yes, ARRY-502 is also known as a CRTh2 antagonist. CRTh2 is another name for the PTGDR2 receptor, which ARRY-502 targets. The terms ARRY-502 and CRTh2 antagonist refer to the same investigational compound.
