What is Involved?

If you choose to join this study, you will get a random assignment (by chance) to 1 of the following 3 study groups:

  • You will take a 20 mg dose of the study drug by mouth twice each day; OR
  • You will take a 80 mg dose of the study drug by mouth twice each day; OR
  • You will take a placebo (inactive substance with no drug in it, "sugar pill") by mouth twice each day

You will take the study drug or placebo for 28 weeks. If you complete the study, you might have the option to enroll in a long-term extension study and continue taking the study drug for at least 2 years. If you got the placebo originally, you will get a 20 mg dose of the study drug in the extension period. Participants who got the study drug originally will continue to take the same dose they were assigned unless the study sponsor determines that one dose is preferable to the other, then everyone in the extension study will take the dose found to be preferable.
