Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
During the 36-month follow-up period, at least one new flare-up (with a maximum of one per year) will be carefully studied. An in-clinic visit will be performed within 14 days following the subject's identification of his/her flare-up. Additional visits at Day 42 and Day 84 (after the initial flare-up clinic visit) will be performed. An additional future visit may be scheduled after Day 84 at the discretion of the Principal Investigator (PI) for prolonged flare-ups. However, subjects with an eligible flare-up may elect to participate in an ongoing Clementia interventional study rather than continue in this natural history study.
