NCT ID NCT07192432

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

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.

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
