What is Involved?

The study drug will be given by an injection under the skin for up to 30 weeks. During the study, you will be asked to come to the study site on a weekly basis.

In addition to receiving the drug, this study involves having physical exams done, monitoring your lesions, ECGs, blood draws, and urine sample collections.

When you become free of symptoms and upon agreement of your study doctor, after the first 6 visits on site, a study nurse can visit your home to give you the study drug injections instead of having on-site visits.
