Phase 1
Recruiting
Conditions
Solid Tumor
Interventions
Registration Number
NCT06368921
Lead Sponsor
Guangzhou Virotech Pharmaceutical Co., Ltd.
Brief Summary

To Evaluate the safety and tolerability of single and multiple intratumoral injections of recombinant oncolytic virus M1 (VRT106) in patients with locally advanced/metastatic solid tumors.

Detailed Description

This study is an open-label, dose-escalation clinical study which aims to evaluate the safety and tolerability of IT injections of VRT106 in subjects with locally advanced/metastatic solid tumors, as well as evaluating the biological distribution characteristics and biological effects of VRT106 (i.e., virus tissue distribution and shedding characteristics), evaluating immunogenicity of VRT106, and preliminarily exploring the anti-tumor effects of VRT106.

Primary Outcome Measures
NameTimeMethod
Evaluate the safety and tolerability of escalating doses of intratumoral injection of VRT106.About 2 years

Incidence rate of TEAE

Characterize the maximum tolerated dose (MTD) or recommended phase 2 dose (RP2D) levels.About 2 years

Incidence rate of DLT

Secondary Outcome Measures
NameTimeMethod
Assess the immunogenicity of intratumoral injection of VRT106.About 2 years

Detect the presence of neutralizing antibodies against VRT106, which represent the potency of the neutralizing antibodies, using the PD50 value.

Examine the biological distribution characteristics and shedding patterns of intratumoral injection of VRT106.About 2 years

Measure the distribution and shedding of VRT106 following intratumoral injection using qPCR (quantitative polymerase chain reaction) method.

Assess the anti-tumor effect of VRT106, including objective response rate (ORR) as efficacy indicators.About 2 years

ORR is defined as the proportion of participants who have a partial response (PR) or complete response (CR) to intervention, based on assessments by RECIST v1.1.

Assess the anti-tumor effect of VRT106, including disease control rate (DCR) as efficacy indicators.About 2 years

DCR is defined as the percentage of participants who have achieved CR, PR, or stable disease (SD) based on assessments by RECIST v1.1.
