Study information
Scientific title
A randomised phase III trial of low dose daily dexamethasone versus intermittent dexamethasone versus prednisolone in hormone refractory prostate cancer (The PoD Trial)
Acronym
PoD
Study hypothesis
The trial aims to evaluate and compare the efficacy of two regimens of dexamethasone (low dose daily and intermittent) and compare them with the standard hormone treatment (Prednisolone) in Hormone Refractory Prostate Cancer (HRPC).

Primary outcome measures
To evaluate the PSA response rate of daily dexamethasone and of intermittent dexamethasone in patients with hormone refractory prostate cancer.
Secondary outcome measures
Added 24 July 2008:
1. To evaluate the clinical and biochemical parameters which influence PSA response to oral steroids in HRPC
2. To evaluate the duration of PSA response to dexamethasone in HRPC
3. To evaluate the time to PSA progression on dexamethasone in HRPC
4. To evaluate the objective response rate using RECIST criteria of dexamethasone in HRPC
5. To evaluate the effect of dexamethasone on pain control and time to skeletal events in HRPC
6. To evaluate the effect of dexamethasone on alkaline phosphatase and haemoglobin in HRPC
7. To evaluate the effect on levels of steroid hormones and steroid metabolites
8. To evaluate the safety and tolerability of dexamethasone in HRPC
9. To evaluate the effect of dexamethasone on overall survival in HRPC
