Malignant Ascites Clinical Trial
Official title:
A Randomized, Controlled, Multi-Center Phase III Clinical Study to Evaluate the Efficacy and Safety of M701 for Intraperitoneal Injection in Patients With Malignant Ascites Caused by Advanced Epithelial Solid Tumors
A Randomized, Controlled, Multi-Center Phase III Clinical Study to Compare the Efficacy and Safety of Recombinant Anti-EpCAM and Anti-CD3 Human-Mouse Chimeric Bispecific Antibody (M701) for Intraperitoneal Injection to Paracentesis alone in Patients with Malignant Ascites Caused by Advanced Epithelial Solid Tumors.
The phase III study is a controlled, open-label trial designed to assess the effectiveness and safety of M701 intra-peritoneal infusion for controlling malignant ascites in patients with Malignant Ascites Caused by Advanced Epithelial Solid Tumors who are also receiving systemic therapy. A total of 270 patients with malignant ascites caused by Malignant Ascites Caused by Advanced Epithelial Solid Tumors will be randomly assigned to two treatment arms in a 2:1 ratio. These patients must have experienced disease progression or intolerance after receiving at least two lines of systemic therapy. Both treatment arms will receive the systemic therapy as per the investigator's instructions. The test arm will receive paracentesis and intra-peritoneal infusion of M701, while the control arm will receive paracentesis alone. The primary endpoint of the study is the puncture-free survival, which evaluates the efficacy of M701 in controlling malignant ascites. Secondary endpoints include the overall survival (OS),Time to next puncture (TTNP), Patient-reported outcome (PRO) score, 6-month survival rate,1-month and 2-month puncture-free survival rate, safety profiles,and Anti-m701 antibody (ADA) and Neutralizing antibody (NAb). ;
