What this trial is trying to do
The researchers are testing whether VET3-TGI, an oncolytic immunotherapy intended to attack cancer cells and stimulate an immune response, can be given safely by injection into a tumour or through a vein. They will test it alone and with atezolizumab, an immune-checkpoint drug, to find suitable doses and assess the combination.
The idea is that pairing VET3-TGI with atezolizumab could produce a stronger immune attack than VET3-TGI alone, but this trial is chiefly measuring whether the treatment can be given safely, through adverse events, rather than whether it helps people live longer or delays tumour growth.
Worth knowing: This is a first-in-human, non-randomised phase 1 trial with no comparison group, and VET3-TGI has not yet been given to patients.
Written from the trial's own registry entry to explain what the researchers are testing and why. Nothing here is a result — this trial has not reported one — and it is not a view on whether the treatment works or on whether it would suit you.

What it is measuring
Incidence of adverse events with VET3-TGI alone or in combination with atezolizumab
This is the trial's main question — the one it is designed and sized to answer. Anything else it reports is a secondary finding, and secondary findings are far more likely to be chance.
Phase 1. Tests safety and dose in a small group. Some people do benefit, but that is not what the trial is designed to find out.
How the researchers describe it
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 atezolizumab in patients with solid tumors (STEALTH-001).

Preferred indications include, but are not limited to, breast carcinoma, bladder carcinoma, cervical squamous carcinoma, colorectal carcinoma, esophageal carcinoma, head and neck squamous carcinoma, renal cell carcinoma, ovarian carcinoma, sarcoma, thymoma, and uterine carcinoma.
- Failed, intolerant to, or refused potentially curative treatment options, including but not limited to, standard of care molecularly targeted agents, immunotherapy (e.g., anti -pembrolizumab/PDL1 antibodies), and chemotherapy
- Measurable disease as per RECIST 1.1 criteria
- At least one tumor amenable to safe ITu injections and/or biopsies
- ECOG performance status 0 or 1
- Demonstrate adequate organ function
- Must be willing to comply with all protocol procedures and adhere to post-treatment care instructions
Additional Inclusion criteria exist
Key Exclusion Criteria
- Prior systemic therapy washout (dependent upon the therapy)
- Requires use of anti-platelet or anti-coagulant therapy that cannot be safely suspended for per protocol biopsies or intra-tumoral injections.
- CNS metastases and/or carcinomatous meningitis that have not been completely resected or completely irradiated.
- Prior history of myocarditis

Where it is running
Running at 7 sites. Listed in: United States.
Individual hospitals, and whether each is currently open, are listed on the registry record. Sites open and close throughout a trial.
Worth asking your oncology team
Being listed here is not a recommendation, and no one page can tell you whether a trial is right for you. These are the questions it raises.
- Is this trial open at a hospital I could realistically travel to?
- Given my stage, my previous treatment and my tumour's molecular profile, would I be eligible?
- What would I be giving up by joining — is the comparison arm the treatment I would otherwise be having?
- What is already known about the safety of what is being tested?
