Purpose
The randomized 2x2x2 factorial design placebo controlled trial will enroll at least 5500 participants (women 60 years or older and men 55 years or older) without known heart disease or prior stroke and without a clear indication or contraindication to any of the study medications. Eligible and consenting individuals will be randomized to receive either the active study medications or placebo (dummy pills) and will be monitored for an average of 5 years. The study will include people from at least 10 countries, will be conducted by an international group of scientists and physicians and will be coordinated by the Population Health Research Institute at Hamilton Health Sciences.

Detailed Description:
Cardiovascular disease (CVD), cancers and osteoporosis collectively make up the largest disease burden globally. CVD is the major cause of death and disability and affects about half of the population over their lifetimes. Cancers are a leading cause of death and it accounts for 13.0% of all deaths. The commonest forms include lung, breast, prostate, colorectum, stomach and liver cancer. It is estimated that over 200 hundred million people worldwide are living with osteoporosis. This is the underlying pathologic predisposition to fractures of the hip, vertebral body, and distal forearm. CVD, cancers and osteoporotic fractures increase with age and so their burden is expected to substantially increase over the next few decades. Simple, safe and effective preventive strategies which can reduce the incidence and prevalence of these 3 diseases are therefore urgently needed
It is suggested that this polypill could be given to all individuals with a CVD event as well as to anyone over 55 years (primary prevention) without the need for any measurement of risk factors. The polypill contains 3 blood pressure lowing medications and a statin in a single tablet. This includes hydrochlorothiazide (25 mg), atenolol (100 mg), ramipril (10 mg) and simvastatin (40 mg). In addition, to the polypill (Polycap), participants will be randomized to receive aspirin (75mg) and vitamin D (60,000 IU monthly). This factorial design on 3 distinct treatment arms which could reduce CVD, fractures and cancers could have large implications for the prevention of several of the important chronic diseases in middle and old age, using safe and inexpensive medications/supplements.
