What will the FDA's decision be on Ivonescimab by Summit Therapeutics in 2026?

If the FDA's decision on Ivonescimab by Summit Therapeutics in 2026 is a full approval or an accelerated approval, the market resolves to Yes. This market will resolve to No if the FDA's decision is a denial (CRL issued), a withdrawal by the sponsor, or a conditional approval — or if no decision is issued. Ivonescimab (also called AK112 or SMT112) is a bispecific antibody — think of it as a single engineered drug molecule that carries two different "hooks" instead of one, allowing it to grab and block two disease-promoting proteins at the same time. It was developed by Akeso and is being commercialized outside China by Summit Therapeutics. By simultaneously neutralizing both targets, ivonescimab is designed to slow cancer growth more effectively than drugs that block only one pathway at a time.
