A Safety Study of TMV-018 in Patients With Tumors of the Gastrointestinal Tract

Detailed Description
This is an open-label, multicenter, dose-escalation phase I trial that aims to determine the safety and tolerability of TMV-018, an oncolytic measles virus encoding the prodrug converting enzyme "super cytosine deaminase", when given alone or in combination with the prodrug 5-Fluorocytosine (5-FC) or an anti-PD-1 checkpoint inhibitor up to day 72 in patients with colorectal carcinoma (left-sided or rectal), esophageal carcinoma, or gastric cancer. Furthermore, the maximum tolerated dose (MTD) and recommended Phase II dose of TMV-018 shall be determined.
At least 15 patients will be enrolled. Patients will be randomized to different treatment groups: all patients will receive intra-tumoral TMV-018 on four visits and additionally 5-FC and/or anti-PD-1 treatment. All adverse events will be documented and analyzed for the primary safety endpoint. Blood and tumor samples will be collected up to day 72 to determine the safety, tolerability and immunogenicity of the treatment. The patients will be followed-up for another two years to determine long-term safety.
