Exhibit 99.1

Roivant Announces Positive IMVT-1402 Initial 600 mg MAD Results that Confirm Best-in-Class Potential
 

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, November 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 https://www.immunovant.com/investors/news-events. 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.

 Graves’ Disease  Large unmet need between oral anti-thyroid medications (ATD) that work for many & definitive therapies that many others require  Ablative 2L therapy (30K/yr in the US) carries radiation or surgical risks and commits the patient to lifelong thyroid replacement therapy  Remaining euthyroid off ATD, for those who achieve it without definitive therapy, is associated with normalizing stimulating anti-TSHR antibodies  High absolute anti-TSHR antibody titers found in many Graves’ patients are likely to require deeper IgG reduction for a durable response  Rheumatoid Arthritis  Large unmet need in refractory rheumatoid arthritis (RA) for patients who fail to respond to more than 1 biologic therapy  Recently presented data for nipocalimab showed a correlation between depth of auto-antibody reduction and clinical response  In the same study, nipocalimab achieved a 58% mean total IgG reduction at trough  Taken together, we believe these points could translate to greater – and meaningful – efficacy in refractory RA with deeper IgG reduction  Examples of Potential First-in-Class and/or Best-in-Class Indications*  24  *For illustration/discussion only. Final indication selection will depend on a variety of factors.  1  2  3  4  1  2  3  4 
 

 Concluding Thoughts 
 

 Favorable Analyte Profile Initial Phase 1 data supports a favorable analyte profile with no or minimal effect on albumin and LDL  * Not including any potential patent term extension  26  IMVT-1402 Has Potentially Best-In-Class Attributes to Address Large Unmet Need in Autoimmune Disease  Novel, fully human, monoclonal antibody inhibiting FcRn-mediated recycling of IgG  +  IMVT-1402  +  +  +  +  +  Convenient Administration Formulated for simple subcutaneous injection that may enable self-administration at home  Compelling Patent Protection Pending composition of matter patent expected for IMVT-1402 to 2043*  Deep IgG Lowering Initial Phase 1 data suggests deep dose-dependent IgG lowering similar to batoclimab 
 

 Concluding Thoughts  27  The proven anti-FcRn class keeps getting more exciting  IMIVT-1402’s profile and potency creates an exciting range of potential indications  2024 will be a big year for IMVT-1402 as we announce a broad portfolio of pivotal trials and POCs
