Study Endpoints
Primary Endpoints
Change from Baseline in MG-ADL Score for Antibody-positive Participants
Baseline to Week 12
Percentage of Group A Participants who remain euthyroid, Off ATD, and Off IMVT-1402
At Week 52
Change from Baseline in clinESSDAI Score at Week 24 for IMVT-1402 Dose 1 compared to Placebo
Baseline and at Week 24

The clinESSDAI is a tool used in clinical studies to measure the systemic disease activity in participants with primary Sjogren's syndrome.

Percentage of participants who are euthyroid and off ATD at Week 26 (Dose 1)
Week 26
Percent change from Period 1 Baseline in Cutaneous Lupus Erythematosus Disease area and Severity Index activity (CLASI-A) score at Week 12
Baseline (Day 1) and Week 12

The CLASI-A score represents the overall severity of cutaneous lupus erythematosus (CLE) dermatologic involvement. It is used to assess the activity of mucocutaneous lesions in patients with lupus. The score ranges from 0 (no active lesions) to a maximum of 70. Values between 1 and 9 indicate mild inflammation, 10 to 20 indicate moderate inflammation, and 21 or higher indicate severe inflammation.

Proportion of participants who maintain ACR20 response at Week 28
Week 28
Percentage of participants who are euthyroid (local laboratory T3 [Total T3 or FT3], FT4, and TSH values within normal limits) and off ATD at Week 26
Week 26
Secondary Endpoints

Baseline to Week 12
Percentage of Antibody-positive Participants Achieving MG-ADL Score of 0 or 1
Week 12
Percentage of Antibody-positive Participants with ≥50% Improvement in MG-ADL Score
