Brief Summary

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

This is a phase I, open-label, dose escalation study to assess the safety, tolerability, efficacy and immunogenicity of TI-0093 injection in patients with recurrent or metastatic HPV-16 positive solid tumors.

The primary objectives of the study are to assess safety and tolerability of TI-0093 injection in patients with recurrent or metastatic solid tumors, and to determine the maximum tolerated doses (MTDs) and recommended Phase 2 doses (RP2Ds) of TI-0093 injection.

Detailed Description

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

All potential study candidates will provide informed consent and undergo screening procedures to determine their study eligibility. After a screening period of up to 28 days, qualified patients will be enrolled to receive their assigned dose of TI-0093 injection. Patients will receive a total of five doses of TI-0093 administered muscularly on Day1, Day8, Day15, Day29 and Day43, respectively. Dose-limiting toxicities (DLTs) will be assessed for at least 28 days after the first dose of a given regimen. During the study, patients will be evaluated for safety, toxicity, immunogenicity, ORR, DOR, DCR, and PFS per protocol.
