Brief Summary:

Study J3Z-MC-OJAE is a Phase 1/2, multicenter, open-label, dose-finding study of LY3884961 evaluating the safety and tolerability in adults with peripheral manifestations of GD.

Up to 3 dose levels of LY3884961 will be assessed in 3 dose-finding cohorts of 3 patients. Following this, up to 6 patients may be enrolled into an expansion cohort.

For each enrolled patient, the study will be approximately 5 years in duration, including up to a 45-day screening period. During the first 18 months after dosing, subjects will be evaluated for the effects of LY3884961 on safety, tolerability, immunogenicity, biomarkers, and efficacy. Patients will be followed up for an additional 42 months to monitor safety, immunogenicity, and selected biomarker and efficacy parameters.
