MOUNTAIN VIEW, Calif., Nov. 08, 2024 (GLOBE NEWSWIRE) -- IGM Biosciences, Inc. (Nasdaq: IGMS), a clinical-stage biotechnology company creating and developing engineered IgM antibodies, today announced its financial results for the fiscal quarter ended September 30, 2024 and provided an update on recent developments.

“The third quarter was transformative for IGM, punctuated by the announcement of our strategic pivot to focus exclusively on autoimmunity,” said Mary Beth Harler, M.D., Chief Executive Officer of IGM Biosciences. "Our near-term focus for imvotamab remains generating robust initial data sets in rheumatoid arthritis, systemic lupus erythematosus and myositis. Based on enrollment timing, we expect to have sufficient information by the middle of 2025 to present initial imvotamab data at an appropriate venue as well as determine next steps to advance imvotamab in autoimmune indications.”

Pipeline Updates

Imvotamab (CD20 x CD3 T cell engager)

• Clinical development of imvotamab in autoimmune diseases advances, with initial clinical data disclosure expected by mid-2025.
  • Third dose cohort in rheumatoid arthritis successfully completed. The Company has cleared the third dose cohort of its placebo-controlled clinical study testing imvotamab in severe rheumatoid arthritis.
  • Enrollment in second dose cohort in systemic lupus erythematosus ongoing. The Company has cleared the first dose cohort of its open-label clinical study testing imvotamab in severe systemic lupus erythematosus (SLE) and is currently enrolling patients in a second dose cohort.
  • First patient dosed in myositis. The Company has dosed the first patient in its single arm, open-label clinical study testing imvotamab in moderate-severe idiopathic inflammatory myopathies (myositis). Enrollment is ongoing in this study, which is being conducted in collaboration with Stanford University.
• Imvotamab preclinical data selected for poster presentation at ACR Convergence 2024. The Company will present a poster titled "Imvotamab, a CD20-Targeted Bispecific IgM T Cell Engager, Effectively Depletes Low-Expressing CD20+ B Cells in Preclinical Models of Autoimmune Disease" at the American College of Rheumatology’s annual meeting, ACR Convergence 2024, taking place in Washington, D.C., on November 17, 2024.
  

IGM-2644 (CD38 x CD3 T cell engager)

• Clinical development of IGM-2644 in autoimmune diseases to be initiated. The Company continues to make significant progress towards initiating clinical development of IGM-2644, a CD38 x CD3 T cell engager antibody, in the treatment of autoimmune diseases. The Company expects to enter IGM-2644 into a single arm, open-label clinical study for generalized myasthenia gravis (gMG) by the end of 2024.
