Our First Participant!

Thanks to the participation from men with suspected prostate cancer and men diagnosed with prostate cancer, we will be able to measure if our “tests” can reveal the true nature of prostate cancer and if the tests or biomarkers can diagnose prostate cancer and tell us what cancers are more aggressive.

As part of the Alberta Prostate Registry and Biorepository, patients will be entered into our study, in which blood and other samples are collected over time and their health outcomes are recorded over many years. Patients will follow standard medical advice and care through their doctors. Our team collect biospecimens and information related to general health and cancer behavior over time.

Rather than being frightened by the word ‘cancer’, we want to learn how to predict serious and morbid prostate cancer complications well before they happen, so that we can weigh carefully the pros and cons of available treatments.

In the process, we expect to identify new and important advantage points for better therapies to be developed. The word “cancer” may be scary, but what is truly scary is unawareness.

“It makes me very happy to be able to contribute to find better ways to diagnose prostate cancer.”

The PRIME Study – Prevention and Intervention for MEtabolic syndrome:

Androgen deprivation therapy (ADT), and newer manipulations of androgen receptor signaling have improved outcomes for advanced prostate cancer (PCa) patients.  The toxicities of ADT are many, including an increased risk of developing metabolic syndrome (MS; defined as at least 3 of: hyperglycemia; abdominal obesity; hypertriglyceridemia; reduced HDL cholesterol; and/or hypertension). MS is associated with an increased risk of diabetes, cardiovascular disease mortality, stroke mortality, and all-cause mortality.  The prevalence of MS in men receiving ADT is at least 50% and contributes to decreased quality of life and increased non-cancer-related mortality.  Metformin holds promise as a countermeasure to MS development, and also has been shown to suppress PCa growth in pre-clinical models.

We hypothesize that the addition of metformin to ADT will reduce the rates of MS in men with advanced PCa, diminishing important toxicities of a therapy universally used in advanced disease.

We propose a double-blind, randomized phase III study of metformin or placebo in men with PCa starting intermittent ADT. The primary endpoint is the difference in MS rates at 1 year.  Other aims include evaluation of the influence of metformin on: individual MS components at additional time points; mean serum insulin levels and measures of insulin resistance; weight and quality of life.

A finding that metformin reduces MS incidence and/or has other benefits would change practice, as it would provide a practical and inexpensive strategy to reduce toxicity of an intervention employed in most men with advanced PCa.
