After granting permission to be contacted, a study representative will call you. During this initial phone call, the study representative will ask additional screening questions and may confirm the answers you have submitted online.

The next step will be to set up an in-person visit to a local study site to enroll in the research study.  Study sites are medical facilities where study-related activities will occur. At your first visit, you will receive additional information about the trial. You may be required to complete further screening at the study site to confirm your eligibility. 


Before enrolling in a study, you will read and sign an informed consent document that gives you a full explanation of all activities that take place during the study. This consent document is not a contract, and a participant can withdraw their consent from the study at any time.

Once you have enrolled, you may receive either the study drug or a placebo. Neither you nor the study doctor will know which group you belong to. A placebo contains no active ingredients and is used to ensure that the changes you report are not due to chance.

You'll be asked to participate in several visits throughout the study. These visits will involve traveling to a nearby study location, usually at healthcare facilities like hospitals or clinics, where you'll participate in study-related activities.
