A Multicenter, Open-label Extension Study Evaluating the Efficacy and Safety of IBI311 in Subjects With Thyroid Eye Disease
November 9, 2023 updated by: Innovent Biologics (Suzhou) Co. Ltd.
A multicenter, open-label extension study evaluating the efficacy and safety of IBI311 in subjects with thyroid eye disease
Study Overview
Detailed Description
This is a multicenter, open-label outreach study.
Participants who have previously participated in and completed CIBI311A201 double-blind treatment can enter this study after signing informed consent.
The study included an observation period and an open treatment period.
Observation period: From weeks D0 to 24, all subjects will return to the research center every 8 weeks for disease evaluation.
If the investigator determines that treatment is required based on predefined criteria, they will enter the open treatment period to receive IBI311 treatment; Otherwise, subjects will continue to be visited every 8 weeks until week 24.
Open Treatment period: Subjects entering the open treatment period will receive 8 infusions of IBI311 (initial dose of 10 mg/kg, followed by 7 maintenance doses of 20 mg/kg, Q3W.
