When you come in for your first visit, you'll go over and sign a form saying you agree to join the study. You'll also talk about your health history and see if you can join the study by doing some simple health checks. You'll give samples like blood and urine. During the study, you'll get the study medicine through a small tube in your arm once every 3 weeks. You'll come back on some days after getting the medicine for more health checks. After your last medicine, we'll keep track of how you're doing for about 30 days, and then every 3 to 6 months for up to 3 years. We'll collect information about any other treatments you're getting and how you're feeling through check-ins at the clinic, or by phone, email, or mail. Let us know about any new feelings or changes in your health during the study.
