Actual (reported)The purpose of the current study is to assess the efficacy and safety/tolerability of three dose regimens of RVT-1401 in the treatment of active, moderate to severe GO participants. In addition, the study is designed to characterize the effect of RVT-1401 exposure on reduction in anti-TSHR IgG

Actual (reported)Percentage of Participants With Proptosis Response at Week 13
Proptosis was assessed using an exophthalmometer. A proptosis response was defined as having at least a 2 millimeter (mm) reduction in study eye proptosis without a deterioration (at least a 2 mm increase) in the fellow eye at the same visit. The study eye was defined as the most severely affected eye at the baseline visit.
Baseline; Week 13
Number of Participants With Treatment-emergent Adverse Events (TEAEs) and Treatment-emergent Serious Adverse Events (SAEs)
AEs - any untoward medical occurrences in a participant, temporally associated with use of a medicinal product, whether or not considered related to the product. Clinically significant changes determined by the Investigator such as vital signs, ECGs, and clinical laboratory values were also reported as AEs. TEAE is defined as an AE that starts on or after the first dose of the study drug and before 30 days after the last dose of the study drug. SAEs were defined as any untoward medical occurrences that: resulted in death; were life-threatening; required hospitalization or prolongation of existing hospitalization; resulted in disability/incapacity; were congenital anomaly/birth defects; were important medical events that may have jeopardized the participant or may have required medical or surgical intervention; invasive or malignant cancers; and development of drug dependency or drug abuse.
