Number of Participants With Any Treatment-emergent Adverse Event (TEAE), Serious AE (SAE), Treatment-related Adverse Event (AE), and Death During the 6-week Treatment Period |
AEs were defined as any untoward medical occurrence in a participant or clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. TEAEs were defined as AEs that either started on or after the date of the first dose of study drug and on or before the date of the last dose of study drug + 42 days, or had no recorded start date and the stop date was in between the date of the first dose and the last dose of study drug + 42 days. SAEs were defined as any untoward medical occurrence that, at any dose: resulted in death, was life-threatening, required hospitalization or prolongation of existing hospitalization, resulted in disability/incapacity, was a congenital anomaly/birth defect, or was an important medical event that may have jeopardized the participant or may have required medical or surgical intervention to prevent one of the other outcomes listed in the definition. |
from Baseline up to Week 6 |
|
Primary |
Number of Participants With Clinically Significant Findings Related to Vital Signs |
Clinical significance was determined by the investigator. |
up to Week 18 |
|
Primary |
Number of Participants With a Change From Normal Physical Examination Findings at Baseline to Abnormal Physical Examination Findings at the End of the Study |
Abnormality was determined by the investigator. |
up to Week 18 |
|
Primary |
Number of Participants With Clinically Significant Findings Related to Electrocardiograms (ECGs) |
Clinical significance was determined by the investigator. |
up to Week 18 |
|
Primary |
Percent Change From Baseline in Total Immunoglobulin G (IgG), IgG1, IgG2, IgG3, and IgG4 Levels |
The serum levels of total IgG and IgG subclasses (1-4) were determined. Percent change from Baseline was calculated as the mean value at the specified time frame (Week 7, Week 6 and 7 combined) minus the Baseline value, divided by the Baseline value x 100. A negative percent change from Baseline represents clinical improvement. |
Baseline; Week 7; Week 6 and 7 combined |
|
Primary |
Mean Change From Baseline in Levels of Anti-thyroid-stimulating Hormone Receptor (Anti-TSHR) Antibodies at Week 7 |
The serum levels of anti-TSHR antibodies were determined. Change from Baseline was calculated as the Week 7 value minus the Baseline value. A negative change from Baseline represents clinical improvement. |
Baseline; Week 7 |
|
Secondary |
Mean Change From Baseline in Proptosis in the Study Eye and Non-study Eye at Week 7 |
The study eye was defined as the most severely affected eye at the Baseline visit. In the event that both eyes were affected the same, the right eye was deemed as the study eye. Participants who did not achieve a proptosis response were censored at the date of their last proptosis measurement that occurred in both eyes. Change from Baseline was calculated as the Week 7 value minus the Baseline value. A negative change from Baseline represents clinical improvement. |
Baseline; Week 7 |
|
Secondary |
Number of Participants With an Overall Proptosis Response |
Proptosis responders were defined as participants with a =2 mm reduction in study eye without deterioration (=2 mm increase) in the fellow eye. Participants who did not achieve a proptosis response were censored at the date of their last proptosis measurement that occurred in both eyes. |
Up to Week 18 |
|
Secondary |
Area Under the Concentration-time Curve From Time 0 to 168 Hours (AUC0-168h) of RVT-1401 |
Pharmacokinetic (PK) parameters were not estimated because the sparse PK sampling schedule did not allow for accurate estimates of these parameters. |
Pre-dose; Day 1, Day 3, Day 5, Day 8, Day 15, Day 22, Day 29, Day 36, Day 38, Day 40, Week 7, Week 8 |
|
Secondary |
Maximum Concentration (Cmax) of RVT-1401 |
PK parameters were not estimated because the sparse PK sampling schedule did not allow for accurate estimates of these parameters. |
Pre-dose; Day 1, Day 3, Day 5, Day 8, Day 15, Day 22, Day 29, Day 36, Day 38, Day 40, Week 7, Week 8 |
|
Secondary |
Serum Concentration at the End of the Dosing Interval (Ctrough) of RVT-1401 |
|
Week 2, Week 3, Week 4, Week 5, Week 6 Day 36, and Week 7 |
|
Secondary |
Number of Participants With Anti-RVT-1401 Antibody and Confirmed Anti-RVT-1401 Antibody at Week 7 |
The serum levels of anti-RVT-1401 antibodies were determined. In the initial analysis the samples with responses equal to or above the plate-specific cut-point were identified as potentially positive while those below the cut-point were considered negative. These potentially positive samples were reanalyzed in confirmatory assay. Samples with percent inhibition greater than or equal to the confirmatory cut-point were considered confirmed positive and those below were considered negative. |
