Item 7.01. Regulation FD Disclosure.

On December 20, 2023, Immunovant, Inc. (the “Company”) issued a press release announcing initial data from its proof-of-concept Phase 2 clinical trial in Graves’ disease. A copy of the press release is attached as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference.

The information furnished under this Item 7.01, including Exhibit 99.1, shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, or the Exchange Act, or subject to the liabilities of that section or Sections 11 and 12(a)(2) of the Securities Act of 1933, or the Securities Act. The information in this Item 7.01, including Exhibit 99.1, shall not be deemed incorporated by reference into any other filing with the U.S. Securities Exchange Commission, or the SEC, made by the Company, whether made before or after the date hereof, regardless of any general incorporation language in such filing.

Item 8.01. Other Events.

On December 20, 2023, the Company announced that results from the initial cohort of patients in an ongoing 24-week Phase 2 clinical trial of batoclimab in patients with Graves’ disease meaningfully exceeded 50% response rates.

This Phase 2 proof-of-concept trial is an open-label study to assess the safety and efficacy of batoclimab in Graves’ disease. Patients who are hyperthyroid despite treatment with an anti-thyroid medication (ATD) for more than 12 weeks are being enrolled to receive once-weekly subcutaneous (SC) injections of 680 mg batoclimab for 12 weeks followed by once-weekly SC injections of 340 mg batoclimab for 12 weeks. Treatment response is defined as normalization of T3 and T4 hormone levels without increasing ATD dose. The primary and secondary outcome measurements of the trial are being measured at weeks 12 and 24. This design allowed for efficacy assessments between two distinct ranges of IgG reductions.

Consistent with studies of batoclimab in other indications, 680 mg administered SC in the initial cohort demonstrated potential best-in class IgG reduction, up to 87%, with a mean IgG reduction of 81% after 12 weeks of treatment. The 340 mg IgG reductions were lower. A similar dose response was observed for anti-TSHR autoantibodies, with deeper reductions observed following treatment with 680 mg of SC batoclimab as compared to 340 mg of SC batoclimab. In addition, across a range of clinical parameters, numerically higher responses were observed following treatment with 680 mg of batoclimab as compared to treatment with 340 mg of batoclimab. These parameters included the percentage of patients whose ATD dose was reduced and the percentage of patients whose ATD was discontinued.  Batoclimab was generally well tolerated with no new safety signals observed in the initial data set.
