Study Endpoints

Primary Endpoints

Change from Baseline in Myasthenia Gravis Activities of Daily Living (MG-ADL) score in acetylcholine receptor (AChR) Ab seropositive (AChRAb+) participants
Baseline (Day 1) to Week 12

MG-ADL is an 8-item, participant-reported questionnaire that assesses gMG symptoms and their effects on activities of daily living. Each item is assessed on a 4-point scale where a score of 0 represents normal function and a score of 3 represents loss of ability to perform that function. Total score ranges from 0 to 24, with higher scores indicating greater functional impairment and disability.

Secondary Endpoints

Change from Baseline in Quantitative Myasthenia Gravis (QMG) score in AChRAb+ participants
Baseline (Day 1) to Week 12
Change from Baseline in MG-ADL score for AChRAb+ randomized withdrawal participants
Baseline (Week 12) to Week 24
Percentage of AChRAb+ participants with greater than equal to (>=) 3-point improvement in QMG score
Up to Week 12

Frequently asked questions about Batoclimab weekly

What is Batoclimab weekly used for?

Batoclimab weekly is an investigational small molecule being developed for generalized myasthenia gravis, a chronic neuromuscular disorder. It is administered as a 680 mg subcutaneous injection on a weekly schedule. The drug is currently in Phase 3 clinical development and has not been approved by regulatory authorities.

What does Batoclimab weekly target?

Batoclimab weekly targets the neonatal Fc receptor (FCGRT) and acts as an inhibitor of this receptor. By blocking FCGRT, the drug is designed to reduce levels of pathogenic IgG antibodies that contribute to the autoimmune attack in generalized myasthenia gravis.

Who makes Batoclimab weekly?

Batoclimab weekly is being developed by Immunovant, Inc., a biopharmaceutical company traded on Nasdaq under the ticker symbol IMVT. The company is conducting a Phase 3 clinical trial to evaluate the drug as induction and maintenance therapy for generalized myasthenia gravis.

What phase is Batoclimab weekly in?

Batoclimab weekly is in Phase 3 clinical development for generalized myasthenia gravis. It is an investigational drug, meaning it has not been approved by the FDA or other regulatory agencies. The ongoing Phase 3 study is active but not recruiting participants.

What clinical trials is Batoclimab weekly in?

Batoclimab weekly is being studied in a single Phase 3 clinical trial registered as NCT05403541. This randomized, double-blind, placebo-controlled study evaluates the efficacy and safety of batoclimab as induction and maintenance therapy in adults with generalized myasthenia gravis, with an enrollment target of 240 participants.

Is Batoclimab weekly the same as Batoclimab 680 mg SC weekly?

Yes, Batoclimab weekly is also known as Batoclimab 680 mg SC weekly. The name reflects the specific dosing regimen of 680 mg administered subcutaneously on a weekly basis. Both names refer to the same investigational drug being developed for generalized myasthenia gravis.
