NCT ID NCT05958121

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 Results may not be published yet.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

Summary

This study tests a new drug called IMA402 in people with advanced solid tumors that have come back or not responded to treatment. IMA402 is designed to help the immune system attack cancer cells. The trial will check if the drug is safe and whether it can shrink tumors.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
IMA402 (a bispecific TCER molecule targeting PRAME)
What this could lead to
If successful, this could lead to a new treatment option for patients with hard-to-treat solid tumors that have not responded to standard therapies.
What could go wrong
This is an early first-in-human trial, so safety and effectiveness are not yet known. The treatment may cause side effects or fail to shrink tumors.
Why investors are watching

Immatics is testing IMA402, a drug that aims to direct the immune system to attack tumors that carry a protein called PRAME, in patients with advanced solid tumors that have stopped responding to other treatments. The trial is a first-in-human study, so the main questions are whether the drug is safe and whether it shrinks tumors, both on its own and with a second drug called pembrolizumab. For a small company like Immatics, this readout matters because IMA402 is one of its key pipeline assets, and the results will show whether the drug has enough promise to continue development.

If it works: If the trial shows IMA402 is safe and produces clear anti-tumor activity, Immatics could advance the drug into later-stage testing and potentially attract a partnership with a larger pharmaceutical company. A positive result would validate the company's technology platform and support its value as a developer of cancer immunotherapies.

If it fails: First-in-human trials often fail because the drug proves too toxic or shows little benefit, and this one is no exception. A poor safety profile or weak tumor response could force Immatics to abandon IMA402, which would be a major setback for a small company with a limited number of pipeline candidates.

Inclusion Criteria: * Patients ≥ 18 years old * Patients must have a specific pathologically confirmed and documented advanced and/or metastatic solid tumor indication * Patients must have received or not be eligible for indicated standard-of-care treatments per cohort * Measurable disease according to RECIST 1.1 * Confirmed HLA status * ECOG Performance Status of 0 to 1 * Adequate baseline hematologic, hepatic and renal function, acceptable coagulation status Exclusion Criteria: * Other active malignancies that require treatment or that might interfere with the trial endpoints * The patient is pregnant or is breastfeeding * History of hypersensitivity to components of IMA402 or rescue medications; hypersensitivity to or contraindication according to current SmPC for respective combination medicinal product * The patient has concurrent severe and/or uncontrolled medical disease.
