• Results from the 600 mg MAD cohort for IMVT-1402 similar to previously disclosed results from the 300 mg MAD cohort for IMVT-1402
  
• IMVT-1402 was observed to deliver dose dependent and deep IgG reductions similar to batoclimab in its Phase 1 study
• IMVT-1402 600 mg was observed to deliver placebo-like impact on albumin and low-density lipoprotein cholesterol (LDL-C), similar to the previously disclosed 300 mg MAD cohort data
• Potential best-in-class profile enables broad and exciting portfolio of indications, taking advantage of IgG reduction we expect will reach 80% with continued weekly dosing of 600 mg delivered by simple subcutaneous injection

NEW YORK, Nov. 28, 2023 (GLOBE NEWSWIRE) -- Immunovant, Inc. (Nasdaq: IMVT), a clinical-stage immunology company dedicated to enabling normal lives for people with autoimmune diseases, today announced initial data from 600 mg MAD cohort of a Phase 1 clinical trial of IMVT-1402 in healthy adults. The results show that four subcutaneously administered doses of 600 mg produced a mean IgG reduction similar to high dose batoclimab, but with minimal changes in albumin and LDL-C similar to those in placebo, confirming the potential of IMVT-1402 as a best-in-class neonatal fragment crystallizable receptor (FcRn) inhibitor.

"We are energized by this potential best-in-class profile, which opens the door to a unique portfolio of first-in-class and best-in-class indications for IMVT-1402, with an emphasis on those indications where potency matters most," said Pete Salzmann, M.D., chief executive officer at Immunovant. "FcRn inhibition is a proven mechanism with broad applicability, and we believe that a growing body of evidence supports a consistent correlation between deeper IgG reduction and greater efficacy. This translates to the potential to build a class-leading anti-FcRn franchise with IMVT-1402."

The Phase 1 clinical trial is a randomized, double-blind, placebo-controlled ascending dose study to assess the safety, tolerability, pharmacokinetics, and pharmacodynamics of IMVT-1402 in healthy adults. Four once-weekly SC injections of 600 mg IMVT-1402 reduced total IgG level by a mean of 74%, a potency that is similar to batoclimab at 680 mg that reduced IgG by 76% after 4 weekly doses. In disease settings where batoclimab was administered continuously, a reduction of 80% was observed at steady state after about 6-8 weeks. We believe steady state IgG reduction with IMVT-1402 will match this result and timing.

Across all doses evaluated, treatments with IMVT-1402 were generally well tolerated with only mild or moderate treatment-emergent adverse events observed. Serum albumin and LDL-C at Day 29 (peak pharmacodynamic impact) did not show a significant decrease or increase, respectively, from baseline (p-values > 0.05).

Conference Call & Webcast:

Immunovant will host a conference call with accompanying slides and a simultaneous webcast today, November 28, 2023 at 8:00 a.m. EST to discuss the 600 mg multiple-ascending dose data. To participate in the conference call, please register in advance here. To access the live and archived webcast, please visit Immunovant's website at . The archived webcast will be available for a limited time on the Company's website.

About IMVT-1402

IMVT-1402 is designed to be a potentially best-in-class anti-FcRn antibody for the treatment of IgG-mediated autoimmune diseases. In the initial results of a Phase 1 clinical trial in healthy adults, IMVT-1402 demonstrated favorable pharmacodynamic and safety data. These attributes, combined with a convenient route of administration that may enable patient self-administration, position IMVT-1402 well as a potential treatment for a variety of autoimmune diseases associated with patient unmet need.

Such forward looking statements include Immunovant's expectations regarding the timing, design, and results of clinical trials of its product candidates; Immunovant's plan to develop batoclimab and IMVT-1402 across a broad range of autoimmune indications; potential benefits of batoclimab's and IMVT-1402's unique product attributes; and IMVT-1402's potential best-in-class profile including IgG reduction and tolerability. All forward-looking statements are based on estimates and assumptions by Immunovant's management that, although Immunovant believes to be reasonable, are inherently uncertain. All forward-looking statements are subject to risks and uncertainties that may cause actual results to differ materially from those that Immunovant expected.
