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 Results may not be published yet.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.

Summary

Researchers are testing a combination of two experimental drugs, JANX013 and JANX007, in men with metastatic castration-resistant prostate cancer, an advanced form that keeps growing despite hormone-lowering treatment. The Phase 1 trial gives both drugs by intravenous infusion to about 110 participants. The main goals are to check safety, find a tolerable dose, and see how the body processes the drugs. The study also looks for early signs of activity, such as changes in prostate-specific antigen (PSA) levels.

What this could mean

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

Active substance
Two experimental drugs, JANX013 and JANX007, given together by intravenous infusion
What this could lead to
If the combination proves safe and shows signs of activity, it could point toward a new treatment option for prostate cancer that has spread and stopped responding to hormone therapy.
What could go wrong
This is a first-in-human Phase 1 trial, so the main goal is to check safety and dosing, not to prove the drugs work. The combination may cause serious immune reactions or other side effects, and early signals of benefit often do not hold up in larger studies.
