NCT ID NCT07370597

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 Results may not be published yet.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.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study looks at whether measuring the exact radiation dose delivered to tumors can predict which patients with advanced prostate cancer will respond to a targeted radioactive therapy called Lu-177 PSMA. Researchers will track 110 men over 12 weeks to see if dose calculations after the first treatment cycle can identify non-responders early. The goal is to personalize treatment by adjusting doses or cycles for each patient.

What this could mean

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

Active substance
Lutetium-177 PSMA radioligand therapy
What this could lead to
If successful, this could allow doctors to personalize radiation doses for prostate cancer patients, potentially improving response rates and reducing ineffective treatments.
What could go wrong
This is an early-stage observational study (110 participants) that does not test a new treatment but rather a prediction method. The approach may not reliably predict outcomes, and results may not apply to all patients.

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

Inclusion Criteria: * Male aged ≥18 years with adenocarcinoma of the prostate. * Progressive metastatic prostate cancer (progression defined as two consecutive increases of PSA, or progression by bone scan or by RECIST1.1). * Candidate for 177Lu-PSMA-RLT, with at least one lesion showing significant PSMA uptake (uptake higher than liver physiologic activity). * Able to start treatment within four weeks of baseline PSMA PET/CT. * Willing and able to comply with all study requirements
