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
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early This study
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

Summary

This early-stage trial is testing a personalized vaccine made from a patient's own immune cells (dendritic cells) to treat prostate cancer. The vaccine is designed to teach the immune system to recognize and attack cancer cells by targeting multiple tumor antigens. The study involves about 30 participants with prostate cancer and aims to evaluate the vaccine's safety and potential benefit.

What this could mean

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

Active substance
A personalized dendritic cell vaccine made from the patient's own immune cells, designed to target multiple prostate cancer antigens.
What this could lead to
If successful, this approach could lead to a new immunotherapy option for prostate cancer that trains the body's own immune system to attack cancer cells.
What could go wrong
This is an early-phase trial with a small number of participants, so the vaccine may not prove effective or safe in larger groups. Possible side effects include immune-related reactions.
