How this study is set up

The points below are drawn from the public registry record for this study. Each one cites the field or sentence it came from. A dash (—) means the record does not state something — not that it is missing or wrong. Many well-run studies, especially small ones, leave some of these blank.

Trial stature

Three independent measures of this study, described from its registry record — not a recommendation about it. A rigorous study by investigators nobody has heard of is better evidence than a weak study led by a famous one. How these are scored.

Investigator standingUNKNOWN

We have no verifiable track record for the investigator named on this trial. That is common for early-career investigators and for records held outside ClinicalTrials.gov — it is not a negative signal.

How this score is built

Investigator standing0/100
No investigator recorded in the registry for this trial

These describe the registry record only, and today we hold ClinicalTrials.gov data. Absent fields lower a score, and absence often reflects registration practice rather than study quality. A high-stature trial is not necessarily safer or a better choice for you — enrolling in a large definitive trial can mean a higher chance of receiving placebo, while a small early-phase study may be the only route to a new therapy.

תקציר

Medicines that reduce the amount of testosterone in the body are commonly used to treat prostate cancer. PRL-02 depot is a potential treatment for men with advanced prostate cancer. It is given by an injection into the muscle. Men with advanced prostate cancer can take part in this study. Their cancer has come back after previous cancer treatment, or the previous cancer treatment they had didn't work. The main aims of the study are: * to check the safety of PRL-02 depot given with and without another medicine called enzalutamide. * to check if the men can tolerate PRL-02 depot given with or without enzalutamide. * to find a suitable dose of PRL-02 depot. This study will be in 2 parts. In the first part, different small groups of men will receive lower to higher doses of PRL-02 depot together with other medicines. In the second part of the study, men who have previously taken a hormone therapy called abiraterone acetate or have previously taken 1 specific hormone therapy as part of their prostate cancer treatment can take part. Men in both parts of the study will receive injections of PRL-02 depot into a muscle once every 12 weeks. They will also take dexamethasone or prednisone, or enzalutamide once a day. The other medicines they take depend on which group and which part of the study they are in. During the study, the men will visit the clinic several times for health checks and scans. After the final visit, men whose cancer has not become worse will continue to have health checks and scans every few months.
