Prostatic Neoplasms study: Triptorelin Injection

Official title Dose Escalation For INtraprostatic LEsions

ClinicalTrials.gov ID: NCT05851547

What this study is testing

What is Triptorelin Injection?

This is an investigational hormone therapy being studied as a treatment for prostate cancer. It is designed to lower the levels of male hormones in the body that can help prostate cancer cells grow.

Also referred to as Androgen Deprivation Therapy.

Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
The study wants to see if giving fewer, larger doses of radiation safely reduces side effects while still targeting cancer spots.
Who it's for
Men with prostate cancer that can be treated with radiation and hormone therapy.
What's involved
Participants will receive three large radiation treatments over one week, guided by MRI to focus on tumor areas, plus standard hormone therapy and regular check‑ups.
Time commitment
The treatment lasts one week, with follow‑up visits for up to one year to monitor side effects.
