Brief Summary

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

VET3-TGI is an oncolytic immunotherapy designed to treat advanced cancers. VET3-TGI has not been given to human patients yet, and the current study is designed to find a safe and effective dose of VET3-TGI when administered by direct injection into tumor(s) (called an intratumoral injection) or when given intravenously (into the vein) both alone and in combination with pembrolizumab in patients with solid tumors (STEALTH-001).

Detailed Description

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

VET3-TGI was changed in a laboratory to infect and kill cancer cells, leaving healthy cells alone. This is a Phase 1 dose escalation (and expansion) study with VET3-TGI administered by direct injection into tumor(s) or by intravenous infusion. The dose escalation has 4 groups: the first group (Group A) will determine the highest tolerated dose of VET3-TGI when injected into tumor(s); the second group (Group C) will determine the highest tolerated dose of VET3-TGI when infused into the vein. The third and fourth groups (Group B and D) will combine VET3-TGI with pembrolizumab. These groups will begin at the highest tolerated dose determined in Group B and Group D, respectively.

Once the highest tolerated dose is found for each of these groups, that dose may be expanded to up to 15 additional patients to better examine the efficacy of VET3-TGI.
