The therapy is currently being tested in individuals with relapsed/refractory ovarian cancer and peritoneal mesothelioma.

What were the results in the first two cohorts: According to the company, in the first two cohorts, the infusion of MCY-M11 has been well-tolerated in all patients treated. No dose-limiting toxicities, infusion-related adverse events, on-target or off-target toxicities, or other unwanted events were observed.
