Description of intervention(s) / exposure
Treatment: Drugs - Leuprorelin Acetate
Treatment: Drugs - Zoledronic Acid
Treatment: Other - Conventional external beam therapy
Active comparator: A - LH-RH analogue for 5 months prior to and during first month of radiation treatment (total 6 mths)
Active comparator: B - LH-RH analogue for 5 months prior to and during first month of radiation treatment (total 6 months) + bisphosphonate therapy.
Experimental: C - LH-RH analogue as for arm A, but continued for further 12 months (total 18 months)
Experimental: D - LH-RH analogue as for arm A, but continued for further 12 months (total 18 months) + bisphosphonate therapy.
Treatment: Drugs: Leuprorelin Acetate
LH-RH analogue (LH-RHa) (Leuprorelin acetate 22.5 mg) will be delivered as a depot injection every 3 months. This will be administered as an intramuscular injection (IMI).
Treatment: Drugs: Zoledronic Acid
Zoledronic acid 4 mg will be delivered as an intravenous infusion over 15 minutes once every 3 months for 18 months, in patients randomised to bisphosphonate therapy.
Treatment: Other: Conventional external beam therapy
The prescribed dose will be 66 Gy in 33 fractions of 2 Gy to the ICRU 50 point utilising a minimum of three fields with \>= 6 MV photons.

Eligibility
Key inclusion criteria
* Histological confirmation of adenocarcinoma of the prostate in the three months prior to randomisation
* Gleason primary and secondary pattern reported. If the volume of tumour in biopsies is too small for the pathologist to allocate a secondary pattern, the primary pattern alone is sufficient.
* Primary tumour stage T2b - 4 (UICC 2002), or T2a providing biopsies demonstrate Gleason score 7 or more, and presenting PSA 10 or more
* PSA value obtained within one month of randomisation
* No evidence of lymphatic or haematogenous metastases, as determined by negative chest x-ray, CT scan of abdomen and pelvis, and bone scan in the 3 months prior to randomisation
* ECOG performance status 0 - 1
* No concurrent medical conditions likely to significantly reduce prospects of 5 year survival
* Patient accessible to follow up at intervals specified in protocol
* Written informed consent given (signed by both patient and investigator prior to randomisation)

Summary
Brief summary
The principal objectives of the RADAR trial is to address the hypotheses; 1) that 18 months androgen deprivation in conjunction with radiotherapy is superior to 6 months androgen deprivation prior to and during radiotherapy; 2) that 18 months Bisphosphonate therapy will prevent bone loss caused by androgen deprivation therapy and further reduce relapse risk by impeding the development of bony metastases.
