Intervention/exposure
Study type
Interventional
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)

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)
Minimum age
18 Years
Maximum age
No limit
Sex
Males
Can healthy volunteers participate?
No
Key exclusion criteria
- Previous or concurrent malignancy within previous 5 years except for non-melanomatous
skin cancer

- Prostatectomy

- Prior pelvic radiotherapy

- Prior hormone treatment for prostate cancer

- Inability to complete self administered QOL questionnaire

- Prior bisphosphonate therapy

- Serum creatinine > 2 x ULN

- Osteoporosis resulting in >30% loss in vertebral height in one or more thoraco-lumbar
vertebrae

- Liver disease resulting in ALT or AST levels >3 x ULN

- Prolonged continuous glucocorticoid therapy > 10 mg/day of prednisone equivalent (>6
months)

- Current treatment with bisphosphonate

- Inability to attend for follow-up at the Investigator's clinic

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.
