Pharmacodynamics
Statistical methods / analysis
A two-stage minimax design will be used to test the primary hypothesis about the frequency of pharmacodynamic (PD) responses in treated patients, with a response defined as 50% or greater decrease in Ki-67 expression in the paired prostate biopsy baseline sample compared with the radical prostatectomy sample.

If fewer than 3 responses are observed in the first 25 treated patients then consideration will be given to modifying or stopping the study. The regimen will be considered to have sufficient activity (greater than or equal to 30% response rate) if at the end of the study at least 8 patients among the 41 treated patients achieve a response.
Fourteen untreated men will be enrolled in the control group to provide estimates of PD biomarkers as a basis for comparison giving a total sample size of 55 patients.


Analysis of efficacy endpoints (i.e., response, biomarkers) will include only evaluable patients. Analysis of safety endpoints (i.e., toxicity) will be according to treatment received, including only patients who received at least 1 dose of the experimental treatment. Where appropriate p-values will be two tailed. A nominal significance level of 0.05 will be applied. Analysis will be performed when evaluable tissue is available from 25 participants treated with AUY922 and at study completion.
Adverse events will be assessed at the interim analysis and at the completion of the study. Serious adverse events will be monitored by the trial management committee on an ongoing basis to ensure that the rate of these events remains acceptable for the study.

Summary
Brief summary
This study will evaluate the effects of a drug, AUY922 which inhibits heat shock protein 90 and may disrupt cancer cell growth in men with high-risk, localised protate cancer.

You may be eligible to join this study if you are male, aged 18 years or over and have been diagnosed with prostate cancer and scheduled for a prostectomy surgery.

The majority of men diagnosed with prostate cancer have disease confined to their prostate and surgery and/or
radiotherapy offers a potential cure. However many men can have the cancer return within 5 - 7 years. Treatments for
these men with recurrent prostate cancer are limited. The purpose of this study is to answer the question if treatment with a new drug called AUY922 (a 60 minute intravenous infusion at 70 mg/m2 on days 1, 8, 15 and 22 over a 28 day cycle) can stop the growth of prostate cancer cells. Prostate cancer cell growth can be measured by a protein called Ki67.

Prostate tissue from biopsies from men with prostate cancer will be collected before treatment with AUY922. All men approached will be having a prostatectomy. After patients have received treatment, their prostate tissue will be collected at surgery evaluated for expression of
Ki67. It is hypothesised that Ki67 expression will be 50% lower compared with before treatment. If there is sufficient activity in the first 25 men who receive treatment, the study will continue to a full experimental cohort of 41 patients. Fourteen (14) patients will be recruited to be a control group with no treatment prior to prostatectomy.
