Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

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

Summary
Brief summary
Less than 20% of men in whom prostate cancer is diagnosed early die from it. Cardiovascular disease is the most common cause of death in men with early prostate cancer. A commonly used form of treatment for prostate cancer is androgen deprivation therapy (ADT). ADT, while effective for the treatment of prostate cancer, has been linked to undesirable side effects, such as an increased risk of bone fractures and diabetes. Bisphosphonates, a class of drugs that prevent bone resorption, have been show to reduce the loss of bone mineral density that occurs as a consequence of ADT, but the effects of bisphosphonates on preservation of bone architecture is unknown.

This project has two main goals:

To assess prospectively, in men with prostate cancer receiving ADT, the effect of:

1. the intravenous bisphosphonate zoledronic acidon ADT-induced microarchitectural decay of bone structure.
2. ADT on insulin resistance and glucose metabolism. We will recruit 100 ambulatory men with non-metastatic prostate cancer who are about to commence a three year course of ADT as per routine clinical practice at Austin Health. Men will be randomised to receive either intravenous zoledronic acid (Aclasta, Novartis Pharmaceuticals) or placebo at baseline and after 12 months of ADT. Men with contraindications to zoledronic acid will be excluded from the study. All 100 study subjects will have clinical and laboratory assessment at baseline, and at 3, 6, 12, 18 and 24 months (study end), and imaging studies at baseline and at 6, 12 and 24 months.

The study protocol is outlined in more detail below (Please see flow chart included in the in

PICF):

Clinical and laboratory assessment:

Full medical history, physical examination and quality of life assessment using the SF-36 questionnaire. Laboratory studies will include: oral glucose tolerance test (3, 12 and 24 months Commercial-in-Confidence only) and measurements of measure total testosterone, fasting glucose, C-peptide, HBA1c, bone turnover markers.

Imaging studies:

1. Bony micro-architecture by high resolution quantitative computed tomography
2. Bone mineral density and body composition by DEXA This project will have no direct benefit for the subjects involved in this study; however, it will improve our understanding on the effect of zoledronic acid on bone microarchitecture in men with prostate cancer receiving ADT. It will also help us to better understand the effect of ADT on insulin resistance and glucose metabolism.
