🇯🇵 Astria Licenses Navenibart to Kaken for Japan in $32M Deal 🧬
Strategic global move by Astria: the company has inked a Japan-exclusive licensing deal with Kaken Pharmaceutical for its lead HAE antibody navenibart, capturing $16M upfront plus up to $16M in milestones, and royalties up to 30% of net sales. 🎯
👉 Kaken will actively support Phase 3 ALPHA‑ORBIT development in Japan, handle local regulatory approvals, and cover a portion of trial costs.
Navenibart’s story:
In the Phase 1b/2 ALPHA‑STAR trial, 1–2 doses over six months cut HAE attack rates by 90–95%, and 67% of patients remained attack-free
The Phase 3 program, initiating in Q1 2025, features both every-3-month and every-6-month dosing schemes, with global registration targeted by early 2027
This partnership deepens Astria’s Japan strategy, accelerates clinical execution, and expands its financial runway through 2028—all while positioning navenibart to be a market-leading, low-burden preventative therapy for HAE.
