Study Treatment

Eligible participants will take part in a 15-week treatment period. Participants will be randomly assigned to receive a liquid formulation of either the investigational drug or placebo. The placebo will look and taste like the investigational drug being tested in the clinical study but has no active ingredients in it.

During the study, participants can expect at least 6 on-site visits for tests and evaluations, as well as 3 telephone visits to review progress. Participants or caregivers will need to maintain electronic diaries throughout the study.
