Immunovant Advances IMVT-1402 with Multiple IND Clearances and New Rheumatoid Arthritis Program
核心洞察
Immunovant's IMVT-1402 receives five IND clearances across various therapeutic areas, paving the way for registrational trials.
A trial evaluating IMVT-1402 in difficult-to-treat rheumatoid arthritis (搜索) (RA (搜索)) is planned, leveraging the drug's potential for deeper IgG reduction.
Batoclimab data in Graves’ disease (搜索) supports the potential for deep IgG reduction to modify disease pathophysiology.
Immunovant, Inc. (Nasdaq: IMVT) has announced significant progress in the development of its lead asset, IMVT-1402, and provided updates on its broader clinical programs. The company reported five Investigational New Drug (IND) applications cleared by the FDA across a range of therapeutic areas. Immunovant remains on track to initiate four to five potentially registrational clinical development programs by March 31, 2025 and anticipates initiating clinical trials evaluating IMVT-1402 in a total of ten indications by March 31, 2026.
IMVT-1402 Development Program Expansion
Following Phase 1 data for IMVT-1402 a year ago, Immunovant is expanding its IMVT-1402 development program into Rheumatology. The first program in Rheumatology will be a potentially registrational study in patients with D2T RA (搜索) where Immunovant believes that deeper IgG reduction has the potential to deliver better clinical outcomes in an important subset of patients with elevated RA-specific autoantibodies (ACPA).
"We believe IMVT-1402 can deliver meaningful clinical benefit in ACPA-positive (ACPA+) D2T RA (搜索) patients, with a potentially best-in-class profile driven by deeper IgG reduction," said Pete Salzmann, M.D., chief executive officer of Immunovant.
Rheumatoid Arthritis Trial Details
Immunovant plans to initiate a potentially registrational trial in ACPA+ D2T RA (搜索) by March 31, 2025. The trial will leverage IMVT-1402’s higher dose (600 mg (搜索)) during the open-label induction phase of the clinical trial to maximize reduction in ACPA levels. FcRn (搜索) inhibition represents an attractive mechanism as a potential treatment for the approximately 70,000 US patients with D2T, ACPA+ RA. Recently disclosed in-class data demonstrated that both higher baseline ACPA levels and deeper ACPA reduction correlated with better clinical improvement in ACPA+ RA patients treated with an FcRn inhibitor.
Graves’ Disease Program Update
In September 2024, Immunovant provided a GD program update consisting of new epidemiologic data characterizing unmet need in GD patients who are relapsed, uncontrolled or intolerant of ATDs, additional results from the batoclimab GD study, and an overview of the IMVT-1402 development program in GD. In November 2024, additional data on the efficacy and safety of batoclimab in Graves’ thyroidal and extrathyroidal disease were presented in an oral presentation at the American Thyroid Association (ATA) 2024 Annual Meeting. These data showed that a 60% response rate (defined as T3 and T4 falling below the upper limit of normal (ULN) without increasing the ATD dose) was achieved by Week 2, demonstrating the rapidity of response to batoclimab 680mg dosed weekly. Meaningful improvements in proptosis and lid aperture were also observed at both Week 12 and Week 24.
The batoclimab data in Graves’ disease (搜索) support the potential for deep IgG reduction to modify the underlying pathophysiology of the disease, which could enable a transformation of the treatment of Graves’ disease for patients not well controlled on ATDs. Immunovant remains on track to initiate the first potentially registrational trial of IMVT-1402 in GD by calendar year end.
Neurology Program Updates
Immunovant completed enrollment of the batoclimab pivotal trial in MG (搜索), with top-line results expected to be reported by March 31, 2025. Results from this trial are expected to inform a decision regarding next steps for batoclimab in MG and the design of the MG program for IMVT-1402, which Immunovant expects to initiate by March 31, 2025.
Enrollment of study participants has completed in the Phase 2b trial evaluating batoclimab in chronic inflammatory demyelinating polyneuropathy (搜索) (CIDP (搜索)) for those patients to be included in the period 1 data readout expected by March 31, 2025. A decision to enroll additional patients in the batoclimab CIDP study will be made following the readout of period 1 data. Those results, as well as observations drawn from public disclosures of other studies in CIDP, will be used to inform the trial design for a potentially registrational program for IMVT-1402 in CIDP.
