Study Overview

• Status: Recruiting
• Conditions: Neoplasms
• Intervention / Treatment: Drug: oncolytic virus (OVV-01) injection

Detailed Description

Phase Ia:

This is a prospective, multicenter, open-label, single-arm investigator-initiated clinical study to evaluate the safety and efficacy of intratumoral injection of OVV-01 injection in patients with advanced solid tumors.

This study plans to enroll in 1 ~ 3 study sites nationwide about 9 ~ 18 patients with advanced solid tumors for whom the standard treatment failed and currently no standard treatment is available or standard treatment is not suitable due to medical reasons, to conduct a phase Ia study, i.e., the First in Human (FIH) trial of OVV-01 injection, using the traditional "3 + 3" approach for dose gradient exploration.

Phase Ib:

This is a prospective, multi-center, open-label, single-arm investigator-initiated clinical study to evaluate the safety and efficacy of intratumoral injection of OVV-01 injection combined with immune checkpoint inhibitors in patients with advanced solid tumors.

This study plans to enroll in 1 ~ 3 study sites nationwide about 12 ~ 24 patients with advanced solid tumors for whom the standard treatment failed and currently no standard treatment is available or standard treatment is not suitable due to medical reasons, to conduct a phase Ib study, using the traditional "3 + 3" approach and based on the phase Ia results, 2 dose gradients of OVV-01 are used in combination with pembrolizumab and atezolizumab, respectively, to explore the efficacy and safety.

Phase Ic:

This is a prospective, multi-center, open-label, single-arm investigator-initiated clinical study to evaluate the safety and efficacy of intratumoral injection of OVV-01 injection combined with immune checkpoint inhibitors in patients with advanced solid tumors.

This study plans to enroll in 1 ~ 3 study sites nationwide about 15 ~ 20 patients with advanced solid tumors for whom the standard treatment failed and currently no standard treatment is available or standard treatment is not suitable due to medical reasons, to conduct a phase Ic study.
