Participants must meet the following criteria:

  • Aged 40 to 80 years, inclusive
  • Agree to use acceptable (at minimum) or highly effective birth control if they are sexually active participants of childbearing potential
  • Be capable of giving signed informed consent
  • Be able, in the opinion of the investigator, to understand the nature of the trial and comply with study's requirements, including the prescribed dosage regimens, scheduled visits, laboratory tests, and other trial procedures

What's involved

You will be in this study for approximately 35 weeks, which includes a screening visit, 27-week treatment period and a safety follow-up phone call. You will need to come to the study centre at least 11 times over this period. Different tests and procedures will be performed at each visit, depending on the type of visit (for example, a screening visit or a treatment visit).

The study is divided into 3 time periods:

  • 4-week screening/baseline period
  • 27-week treatment period
  • 4-week post-treatment safety follow-up period

If the study doctor determines that you meet all the requirements to be in the study, you will be randomly assigned (like flipping a coin) to receive either the study drug or the placebo.
