Gene therapy takes aim at Hard-to-Treat HER2 cancers
NCT ID NCT07192432
First seen Jun 24, 2026 · Last updated Jul 29, 2026 · Updated 4 times
Summary
This study tests a new gene therapy called VNX-202 for people with HER2-positive solid tumors. The therapy uses a harmless virus to deliver instructions that help the body's immune cells attack cancer. The trial has two parts: one for advanced cancers that have stopped responding to standard treatments, and another for early-stage cancers at high risk of coming back. Researchers will monitor safety and whether the treatment controls tumor growth.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- VNX-202 gene therapy (a virus that delivers instructions to make cancer-fighting immune proteins)
- What this could lead to
- If it works, this could offer a new treatment option for people with HER2-positive cancers that have stopped responding to other therapies.
- What could go wrong
- This is a very early, first-in-human study with only 27 participants. The therapy may not shrink tumors or could cause serious side effects. Success in early-stage disease is not guaranteed.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Age: ≥18 years of age * Histologically or cytologically confirmed diagnosis of HER-2 positive solid tumor as defined in the protocol * Part 1: presence of advanced or metastatic disease that has progressed during or following previous treatment * Part 2: Early stage HER-2 positive cancers with high risk for relapse following completion of SOC or after neoadjuvant systemic treatment * AAV specified capsid total antibody ≤1:400 * ECOG performance status of 0 or 1 * Life expectancy ≥3 months * Protocol-specified ranges for renal, liver, cardiac and pulmonary function * Protocol-specified ranges for hematology parameters Exclusion Criteria: * Hepatoxicity (AST or ALT \> 2x upper limit of normal) * Known active CNS or leptomeningeal disease * History of thrombotic microangiopathy or cardiomyopathy, or evidence of sensory neuropathy * Pregnant or nursing (lactating) women * History of other malignancy within 5 years prior to screening as defined in protocol * History of hypersensitivity to corticosteroids or history of corticosteroid-related toxicity Concurrent anti-cancer treatment in another investigational trial
