Engineered t cells take on Hard-to-Treat prostate cancer

NCT ID NCT07285694

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 treatment called AB-3028, which uses a patient's own immune cells (T cells) that have been modified in a lab to better attack prostate cancer cells. It is for men with metastatic castration-resistant prostate cancer, a type that has stopped responding to hormone therapy. The trial will enroll 190 participants to check safety and find the best dose.

What this could mean

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

Active substance
AB-3028 (engineered T cells)
What this could lead to
If successful, this could lead to a new treatment option for men with advanced prostate cancer that has stopped responding to standard therapies.
What could go wrong
This is an early-phase trial (Phase 1/2) with a small number of participants, so the treatment may not prove effective or safe. T cell therapies can cause serious side effects like cytokine release syndrome.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Key Inclusion Criteria: 1. At least 18 years of age at time of signing informed consent form. 2. Histologically confirmed adenocarcinoma of the prostate, meeting all of the following criteria: • Documented progressive metastatic castration-resistant prostate cancer (mCRPC) based on PCWG3 criteria. 3. Prior prostate cancer treatment with at least 1 novel androgen receptor pathway inhibitor (ARPI) therapy. • PSMA+ by PSMA PET. * Measurable disease by RECIST 1.1 criteria, or evaluable disease via measurable PSA (≥ 1 ng/mL) per PCWG3 criteria. 4. Adequate organ functions. Key Exclusion Criteria: 1. Any prior systemic therapy for CRPC within 14 days prior to scheduled protocol required leukapheresis. 2. Central nervous system (CNS) metastatic disease, leptomeningeal disease, or cord compression. 3. Unwillingness to participate in an extended safety monitoring period.
