Frequently asked questions about AZD5055

What is AZD5055 used for?

AZD5055 is being developed for idiopathic pulmonary fibrosis, a progressive lung disease marked by scarring of lung tissue. It is an investigational small molecule and has not been approved for any indication. The completed Phase 1 study enrolled healthy participants rather than patients with idiopathic pulmonary fibrosis.

Who is developing AZD5055?

AZD5055 is developed by AstraZeneca PLC, which trades on the Nasdaq under the ticker AZN. AstraZeneca is the sponsor of the clinical program for the asset in idiopathic pulmonary fibrosis.

What phase is AZD5055 in?

AZD5055 is in Phase 1 development. One Phase 1 trial has been completed, and no active trials are currently listed. The drug remains investigational and has not been approved by the FDA or any other regulator for idiopathic pulmonary fibrosis or any other condition.

What clinical trials is AZD5055 in?

AZD5055 has been studied in one completed Phase 1 trial, NCT05134727, titled a study to assess the safety, tolerability and pharmacokinetics of AZD5055 following single and multiple ascending doses in healthy participants. It was a randomized, double-blind, controlled trial that enrolled 63 healthy volunteers in the United States.

Is AZD5055 the same as AZD5055 oral suspension?

Yes. AZD5055 oral suspension is an alternative name for AZD5055, referring to the oral suspension formulation of the same investigational small molecule being developed by AstraZeneca for idiopathic pulmonary fibrosis.
