Prescribing Notes:
- Prostap® is the first line LHRH agonist for new patients with prostate cancer based on regional recommendations following the development of a national consensus statement.

- Use in adult men who have received only one prior chemotherapy regimen. Click here for regional protocol [NHS network access required]
- With prednisone or prednisolone for the treatment of newly diagnosed high-risk metastatic hormone sensitive prostate cancer in adult men in combination with androgen deprivation therapy. Click here for regional protocol [NHS network access required]
Non-metastatic prostate cancer:
- Use of abiraterone acetate plus prednisolone in combination with androgen deprivation therapy for the treatment of high-risk hormone-sensitive non-metastatic prostate cancer (off label indication as approved by NCMAG).
Metastatic prostate cancer:
- Abiraterone acetate plus prednisolone in combination with androgen deprivation therapy for the treatment for newly diagnosed low-risk metastatic hormone-sensitive prostate cancer patients who are not suitable for currently accessible on-label alternatives (off label indication as approved by NCMAG).
Restrictions:
Restricted to specialist use in accordance with regional protocol [local network access required] for the indications outlined below.
-
Treatment of adults with metastatic hormone-sensitive prostate cancer (mHSPC) in combination with androgen deprivation therapy (ADT).
- In adults for the treatment of non-metastatic castration-resistant prostate cancer (nmCRPC) who are at high risk of developing metastatic disease.

Restricted to specialist initiation. Owing to the risk of hepatotoxicity, cyproterone should be used for long-term treatment only where other treatments are not tolerated.
Restrictions:
The treatment of adult male patients with advanced hormone-dependent prostate cancer is restricted to specialist initiation in accordance with regional protocol.

Restrictions:
Prostate cancer
