Business Description

Overview Immunovant, Inc. (“Immunovant,” “we” or the “Company”) is a clinical-stage immunology company dedicated to enabling normal lives for people with autoimmune diseases. Our focus is on developing IMVT-1402 (imeroprubart), a potentially best-in-class inhibitor of the neonatal fragment crystallizable receptor (“FcRn”), to address autoimmune diseases driven by high levels of pathogenic immunoglobulin G (“IgG”) antibodies. FcRn is involved in preventing the degradation of IgG antibodies, and inhibition of FcRn has been shown to reduce levels of total IgG and pathogenic IgG antibodies. We believe that FcRn inhibition has broad therapeutic and commercial potential to address pathogenic IgG-mediated autoimmune diseases in several therapeutic areas, including but not limited to, endocrinology, neurology, rheumatology and dermatology. Third-party estimates suggest over four million patients in the United States and Europe could benefit from anti-FcRn treatments across more than 20 indications that have been publicly announced for research and development by multiple companies, with two indications that are already approved and launched quickly reaching multi-billions of dollars in global annual sales. Consistent evidence observed across the class in eight indications in Phase 2 and 3 trials with FcRn inhibitors has indicated that deeper IgG reductions correlate with meaningful improvements in clinical outcomes. This has also been validated with Immunovant’s own Phase 2 and 3 studies evaluating its first-generation anti-FcRn antibody, batoclimab, in Graves’ disease (“GD”), myasthenia gravis (“MG”) and chronic inflammatory demyelinating polyneuropathy (“CIDP”) which showed that IgG reductions of greater than or equal to 70% led to meaningfully better outcomes compared to reductions below 70% across a range of clinical measures. In a Phase 1 clinical trial, healthy adults dosed with IMVT-1402 showed deep, dose-dependent IgG reductions. We expect to be able to reach approximately 80% IgG reductions with continued weekly dosing of 600 mg of IMVT-1402, offering deeper IgG reductions than observed with other competitor anti-FcRn programs, therefore representing a potential best-in-class opportunity. In the Phase 1 clinical trial, across all evaluated doses, IMVT-1402 demonstrated no or minimal reductions in albumin and no or minimal increases in LDL cholesterol levels, which are off-target effects observed in some anti-FcRn antibodies, including batoclimab. We believe IMVT-1402’s profile has the potential to offer best-in-class efficacy, in addition to its potentially favorable safety profile and convenient administration with a simple self-administered auto-injector expected at launch. We are currently progressing a broad set of programs for IMVT-1402 and have ongoing studies in six indications, including potentially registrational trials in GD, difficult-to-treat rheumatoid arthritis (“D2T RA”), MG, CIDP and Sjögren’s disease (“SjD”), and a proof-of-concept trial in cutaneous lupus erythematosus (“CLE”). Our primary focus is to execute these six indications first, with plans to assess new indications for IMVT-1402 in the future. All studies evaluating IMVT-1402 are being conducted using the intended commercial drug formulation and delivery device, the YpsoMate® autoinjector developed by Ypsomed AG, which is utilized for multiple approved products. IMVT-1402 and batoclimab are fully human monoclonal antibodies that target FcRn. These antibodies are the result of a multi-step, multi-year research program conducted in collaboration with HanAll to design highly potent anti-FcRn antibodies that may be optimized as a simple, subcutaneous injection with dosing that has been shown to deliver better efficacy at the high dose and similar efficacy at the low dose compared to standard FcRn inhibition by competitors. In April 2026, we announced top-line results from two Phase 3 clinical studies evaluating batoclimab as an investigational treatment for adults with active, moderate-to-severe thyroid eye disease (“TED”), neither of which met the primary endpoint. The safety profile observed in these studies was consistent with prior batoclimab studies, with no new safety signals identified. Following these results, we made a decision to discontinue further development of batoclimab across all indications to focus fully on IMVT-1402.…
