研究概览
详细说明
This Phase 2 study will evaluate the safety and efficacy of AGA2115 in three different dosing regimens in Chinese adults and adolescents with Type I, III, or IV OI. Participants will be in the study for 24 or 27 months depending on their assigned cohort. During the first 12 months of the study, adult and adolescent participants will be randomized separately in a 1:1:1:1 ratio to one of three AGA2115 dosing regimens or control cohort. During months 12 to 24 or 27, all participants will receive AGA2115 and attend visits for the evaluation of safety and efficacy parameters.
