Treatment of advanced solid tumors with VET3-TGI immunotherapy
Official title: A Phase 1/1b Study of VET3-TGI Administered Alone and in Combination With Atezolizumab in Patients With Advanced Solid Tumors
Run by KaliVir Immunotherapeutics · NCT06444815 · Data updated 2026-11-12
This study is testing a new cancer treatment called VET3-TGI to see if it can safely target and kill cancer cells in patients with advanced solid tumors, either by injecting it directly into the tumors or giving it through an IV.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include adults with advanced, unresectable, or metastatic solid tumors who have failed or are intolerant to standard treatments.
✕Probably not a fit
Patients with early-stage tumors or those who have not yet undergone standard treatment options may not benefit from this study.

What this trial studies
This clinical trial investigates VET3-TGI, an oncolytic immunotherapy designed to target and kill cancer cells while sparing healthy cells. The study is a Phase 1 dose escalation trial that will assess the safety and efficacy of VET3-TGI administered either through direct injection into tumors or intravenously, both alone and in combination with pembrolizumab. The trial will involve multiple groups to determine the highest tolerated doses of VET3-TGI and will expand to include additional patients for efficacy evaluation once these doses are established.
Why it matters
Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with advanced solid tumors who have limited treatment alternatives.
How similar studies have gone: While this approach is novel in its specific application, similar oncolytic immunotherapies have shown promise in other studies.
