NCT ID NCT06402201

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 Results may not be published yet.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

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.

Summary

This early-phase trial tests a new drug called CDR404 in up to 42 adults with advanced solid tumors that have a specific marker (MAGE-A4) and tissue type (HLA-A*02:01). The drug is designed to help the body's immune T-cells find and attack cancer cells. The main goals are to check safety, find the right dose, and see if the drug 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
CDR404 (a bispecific antibody that engages T-cells to attack cancer cells)
What this could lead to
If it works, this could point toward a new treatment option for certain hard-to-treat solid tumors that express the MAGE-A4 protein.
What could go wrong
This is a very early, first-in-human trial with only 42 participants, so safety and effectiveness are not yet known. The treatment may cause side effects or fail to shrink tumors.
