COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Key exclusion criteria
1. Contraindications to investigational product including hypersensitivity, treatment
with any CYP3A4 inducer or inhibitor or known G6PD deficiency. If on a statin, must be
changed to rosuvastatin or ceased, as appropriate

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

4. Prior systemic therapy for advanced cancer prostate cancer such as hormonal therapy or
chemotherapy; neo/adjuvant hormonal therapy allowed if = 24 months total duration and
ceased = 12 months prior to enrolment

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.

8. Serious medical or psychiatric conditions that might limit the ability of the patient to
comply with the protocol.

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

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.
