A focused company with a single purpose.

AirNexis Therapeutics is a clinical-stage biotechnology company headquartered in Redwood City, California. We were founded in January 2026 with a $200 million Series A.

We are working to deliver a next-generation maintenance therapy for COPD that may provide improved efficacy and an enhanced patient experience compared to currently available treatments. We are small, focused, and moving quickly — because the people waiting on better options have waited long enough.
