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

Change from Baseline in Quantitative Myasthenia Gravis (QMG) Score for Antibody-positive Participants
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

Frequently asked questions about IMVT-1402

What is IMVT-1402?

IMVT-1402 is an investigational small molecule drug being developed by Immunovant, Inc. (ticker IMVT). It is in Phase 3 clinical development for generalized myasthenia gravis and is also being studied in Graves' disease, cutaneous lupus erythematosus, and other autoimmune indications. It has not been approved by the FDA and remains under clinical investigation.

What does IMVT-1402 target?

IMVT-1402 targets the neonatal Fc receptor, commonly known as FcRn. By binding to FcRn, the drug is designed to reduce recycling of immunoglobulin G antibodies, lowering circulating IgG levels. This mechanism is being explored across several autoimmune conditions in which pathogenic IgG antibodies are thought to play a role.

Who makes IMVT-1402?

IMVT-1402 is being developed by Immunovant, Inc., which trades on the Nasdaq under the ticker IMVT. Immunovant is the sponsor of the clinical trials evaluating the drug across generalized myasthenia gravis, Graves' disease, and cutaneous lupus erythematosus.

What phase is IMVT-1402 in?

IMVT-1402 is in Phase 3 development. The Phase 3 trial is in generalized myasthenia gravis, while studies in Graves' disease and cutaneous lupus erythematosus are Phase 2. The drug is investigational and has not received FDA approval. Three trials are currently active, with no completed trials reported.

What clinical trials is IMVT-1402 in?

IMVT-1402 is being evaluated in several trials. NCT07039916 is a Phase 3 study in generalized myasthenia gravis. NCT07018323 is a Phase 2 study in Graves' disease, and NCT07286006 is a Phase 2 long-term extension study in Graves' disease. NCT06980805 is a Phase 2 study in cutaneous lupus erythematosus.

What is IMVT-1402 used for in generalized myasthenia gravis?
