Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This first-in-human (FIH) trial is designed to assess the safety, feasibility, and potential activity of a single intravenous (IV) dose of SynKIR-110 administered to subjects with mesothelin-expressing advanced ovarian cancer, mesothelioma, and cholangiocarcinoma.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a Phase 1, FIH, multicenter, open-label, dose-escalation pilot study of a single IV gravity drip infusion of SynKIR-110 in subjects with advanced, mesothelin-expressing tumors (ovarian cancer, primary peritoneal cancer, fallopian tube cancer, cholangiocarcinoma, or mesothelioma). Up to 42 subjects will be assessed to determine the safety and feasibility of treatment with SynKIR-110. Informed consent will be obtained from subjects prior to participation in this study.

The study includes an enrollment screening period (which includes pre-leukapheresis safety/eligibility and leukapheresis visits), treatment period (administration of non-myeloablative lymphodepleting chemotherapy followed by a single infusion of investigational product), and a 12-month follow-up period or until disease progression. Subjects will be followed for 12 months or until confirmed disease progression, whichever occurs first, at which point they will be invited to participate in a long-term safety follow-up study.

Up to 6 cohorts of 3 to 6 subjects per cohort will be treated to determine the safety and feasibility of treatment with SynKIR-110. Doses will be escalated following a standard 3 + 3 design until either an MTD or MFD is reached. An additional 6 to 9 subjects will be treated at the MTD/MFD to further assess safety and potential activity of SynKIR-110.
