How could Akeso's US clinical trial expansion affect the FDA?
US clinical trial expansion increases FDA oversight of ivonescimab. The expansion of clinical trials for ivonescimab into the United States, specifically the Phase III EA2251 study, means the drug is entering the formal U.S. regulatory pathway. Akeso has out-licensed the exclusive rights to develop and commercialize ivonescimab in the United States to Summit Therapeutics. As a result, the FDA must formally monitor and regulate the progress of this registration-enabling study and subsequent data to determine if the drug can achieve U.S. market approval.

How it reaches FDA
-
Akeso and Icahn School of Medicine at Mount Sinai have partnered to expand clinical trials for ivonescimab into the United States, with site activations expected in Q4 2026. This collaboration marks the seventh international registrational Phase II/III clinical trial for ivonescimab. The new trial, EA2251, will evaluate ivonescimab with chemotherapy against current immunotherapy standards of care for biliary tract cancer.

The facts so far
As reported. Each one links to where it comes from.
- Ivonescimab is a first-in-class PD-1/VEGF bispecific antibody independently developed by Akeso.manilatimes.net
- The Phase III HARMONi-GI1 study achieved a positive overall survival (OS) result.manilatimes.net
- EA2251 is the second Phase III registrational clinical study of ivonescimab in BTC.manilatimes.net

Why it matters
The success of ivonescimab in this US trial is critical for its potential to become a superior treatment option for patients with biliary tract cancer globally. Biliary tract cancer is often diagnosed at an advanced stage, and there is a recognized need for more effective first-line options that can extend survival and improve disease control.
Akeso is advancing a comprehensive global development program for ivonescimab, which includes over 18 Phase III studies worldwide. This positions ivonescimab as a cornerstone of Akeso's IO2.0 + ADC2.0 strategy, aiming to reshape standards of care in major cancers.
