2. Evidence of metastatic disease on conventional WBBS or CT. However low volume regional nodes (= N1, up to the aortic bifurcation) may be accepted in asymptomatic patients.
3. PSA doubling time = 3 months calculated using MSKCC calculator (https://www.mskcc.org/nomograms//prostate/psa-doubling-time)

5. Life expectancy of = 1 year
6. History of another invasive cancer within 3 years before screening with the exception of fully treated cancer with remote probability of recurrence
7. Concurrent illness, including severe infection that may jeopardize the ability of the patient to undergo the procedures outlined in this protocol with reasonable safety
8. Use of hydroxychloroquine and/or itraconazole for any indication in the preceding 2 years or at any time for treatment of prostate cancer.

9. Men must have been surgically sterilised or use a barrier method of contraception.

10. Pre-existing retinopathy, keratopathy or other ocular pathologies that, in the opinion of an ophthalmologist would put the patient at risk of hydroxychloroquine induced retinopathy 11. History of cardiac failure or recent history if ischaemic heart disease (<2 years)

Summary
Brief summary
Recent pre-clinical work has suggested that Itraconazole has an anti-cancer effect that works synergistically with hydroxychloroquine. This may delay the need for androgen deprivation therapy (ADT) and its associated toxicities in men with biochemically recurrent (BCR) prostate cancer. This study aims to determine feasibility, safety and efficacy of suba-itraconazole (SI) in combination with hydroxychloroquine (HQ) in the treatment of biochemically recurrent (BCR) prostate cancer as means of delaying time to commencement of androgen deprivation therapy.
