Astria Therapeutics Announces Publication of Navenibart Phase 1a Healthy Subject Results in the Annals of Allergy, Asthma & Immunology
“We are thrilled by our publication in the Annals of Allergy, Asthma & Immunology and the opportunity to provide additional information that affirms our belief in navenibart’s potential to become the first-choice therapy for HAE,” said
Overview of results from the Phase 1a trial of navenibart in healthy subjects:
- For all doses ≥300 mg, navenibart mean half-life ranged from 82 to 105 days, supporting the potential for administration every 3 and 6 months. Navenibart’s inhibition of plasma kallikrein activity versus placebo was statistically significant (P<0.05).
- Navenibart was well-tolerated, with similar rates of adverse events between navenibart and placebo, and no serious adverse events were observed.
- Results demonstrated early proof of concept for navenibart as a potential long-acting therapy for HAE.
