NCT ID NCT07428642

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 This study
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 Results may not be published yet.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

Summary

This study looked at 168 men with metastatic hormone-sensitive prostate cancer to see if a model using PSMA-PET scans and routine medical information could predict how well they would respond to standard first-line treatment. The goal was to help doctors better understand which patients are likely to have a strong early response, without any extra tests or procedures. The findings could support more personalized follow-up and treatment planning.

Multicenter retrospective cohort of male patients with metastatic hormone-sensitive prostate cancer (mHSPC) treated in routine clinical practice. Participants had baseline PSMA PET/CT prior to first-line therapy and available clinical variables and PSA follow-up for outcome assessment.

Ages

Children (under 18), adults (18 to 64) and older adults (65 and over)

Sex

Male participants only

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

Inclusion Criteria: * Male patients diagnosed with metastatic hormone-sensitive prostate cancer (mHSPC). Distant metastasis confirmed by conventional imaging and/or PSMA PET/CT. Received first-line standard therapy based on androgen deprivation therapy (ADT) with an androgen receptor signaling inhibitor (ARSI), with or without docetaxel, as part of routine clinical care. Baseline PSMA PET/CT performed prior to initiation of first-line therapy. Availability of required baseline clinical data and PSA follow-up data. Exclusion Criteria: * History of or concurrent other primary malignancies. Non-adenocarcinoma prostate cancer histology (e.g., neuroendocrine tumors). Received prostate cancer therapies not consistent with the protocol-defined first-line setting around diagnosis (e.g., surgery, radiotherapy, chemotherapy other than protocol-defined docetaxel, targeted therapy, immunotherapy). Follow-up duration \< 3 months after treatment initiation.
