Frequently asked questions about STAR-0215

What is STAR-0215 used for?

STAR-0215 is an investigational small molecule being developed for the treatment of hereditary angioedema, a rare genetic condition characterized by recurrent episodes of severe swelling. It is currently in Phase 2 clinical development and has not been approved by regulatory authorities.

What does STAR-0215 target?

STAR-0215 targets plasma kallikrein, a protein involved in the inflammatory pathway that leads to swelling in hereditary angioedema. By inhibiting this target, the drug aims to reduce the frequency and severity of angioedema attacks.

Who is developing STAR-0215?

STAR-0215 is being developed by Astria Therapeutics, Inc., a biopharmaceutical company traded on the Nasdaq under the ticker symbol ATXS. The company is conducting clinical trials to evaluate the drug's safety and efficacy in patients with hereditary angioedema.

What phase is STAR-0215 in?

STAR-0215 is currently in Phase 2 clinical development. It has completed a Phase 1 trial in healthy volunteers and is now being studied in a long-term Phase 2 trial in patients with hereditary angioedema. The drug remains investigational and is not yet approved.

What clinical trials is STAR-0215 in?

STAR-0215 has been studied in two clinical trials. NCT05477160 was a completed Phase 1 study in 41 healthy adult participants in the United States. NCT06007677 is an active Phase 2 long-term study in 56 participants with hereditary angioedema across multiple countries, including the United States, Bulgaria, Canada, Czechia, Germany, Poland, and the United Kingdom.
