If you choose to participate, you will have 17 visits for a little over 1 year. Most visits will be about 4 weeks apart; some will be 2 weeks apart. Visits are typically about 2 hours long, but the first visit, two injection visits, and the second to last visit will take about 6 hours. There are also some visits where we can do a telehealth visit with you, so you won't need to come to clinic. We will be asking you some questions, providing you a mobile device for you to complete questions once a day, conducing physical exams and vital signs, having doctors look inside your nose (nasal endoscopy), going for a CT Scan at the beginning and end of the study, looking at the electrical activity of your heart (Electrocardiogram (ECG)), asking you about your health and your medications, doing blood and urine tests, if you are able to become pregnant we will check to see if you are pregnant, and providing the study drug or a placebo. The placebo contains no active medicine. Like the study drug, it will be given as one injection under the skin every 6 months. Clinical trials often include a placebo so that effects seen in people who receive a study drug can be compared to effects seen in people who do not receive a study drug.
