– Company to prioritize its pipeline of T cell engagers in autoimmune diseases, including ongoing clinical development of imvotamab in rheumatoid arthritis and systemic lupus erythematosus – – Mary Beth Harler, M.D., appointed as Chief Executive Officer and to Board of Directors – – Cash runway extended into 2027 – – Company to hold conference call and webcast today at 4:30 p.m. EDT – MOUNTAIN VIEW, Calif., Sept. 30, 2024 (GLOBE NEWSWIRE) -- IGM Biosciences, Inc. (Nasdaq: IGMS), a clinical-stage biotechnology company creating and developing engineered IgM antibodies, today announced a strategic pivot and pipeline transformation to accelerate and deepen its leadership in the development of T cell engaging IgM antibodies for the treatment of autoimmune diseases. The Company’s lead candidates include imvotamab, a CD20 x CD3 bispecific T cell engager being developed in rheumatoid arthritis, systemic lupus erythematosus and myositis, and IGM-2644, a CD38 x CD3 bispecific T cell engager, which is expected to enter into a clinical study for generalized myasthenia gravis by the end of 2024. IGM also announced today that Mary Beth Harler, M.D., an industry veteran with extensive experience in delivering innovative new therapies in autoimmunity, has been appointed as Chief Executive Officer and to the Board of Directors. Dr. Harler joined IGM in 2021 as President, Autoimmunity and Inflammation following an 11-year career at Bristol Myers Squibb. At Bristol Myers Squibb, Dr. Harler served as Senior Vice President, Head of Immunology and Fibrosis Development, where she successfully led a team of global professionals and oversaw late-stage development of innovative therapies such as SOTYKTU®, ORENCIA® and ZEPOSIA®. Dr. Harler trained as a general surgeon at Brown University’s Rhode Island Hospital. “Mary Beth’s experience over the last three years leading our autoimmune research efforts, together with her extensive prior clinical development experience, make her ideally suited to lead IGM as we shift our focus to the development of T cell engagers for autoimmunity and extend the Company’s cash runway into 2027,” said Felix J Baker, Ph.D., director at IGM Biosciences. "We are excited by Mary Beth's vision and passion to bring forward a new treatment modality to patients suffering from autoimmune diseases and believe she will be a strong leader for IGM." “Our early pivot to using T cell engagers in autoimmune disease has enabled significant progress on these programs at IGM, and I am excited to lead the Company at this transformational stage,” said Dr. Harler. “We’ve made great progress in our clinical development of imvotamab in autoimmune indications and we believe the clinical, and ultimately commercial, potential of our pipeline of T cell engaging antibodies in treating autoimmune diseases is significant. As we have previously guided, we look forward to sharing initial clinical data from the imvotamab studies later this year or in early 2025.” Pipeline Updates Aplitabart (death receptor 5 agonist) IGM to minimize future spending on aplitabart and other oncology candidates. In light of the emerging data from the Company’s ongoing randomized clinical trial of aplitabart in second-line metastatic colorectal cancer, together with the significant opportunity in autoimmunity, the Company has decided to immediately begin taking steps, including a reduction in force, to minimize its future spending on the research and clinical development of aplitabart and other oncology candidates. Final data from the randomized clinical trial of aplitabart in second-line metastatic colorectal cancer will be shared in an appropriate forum in the future. As a result of these actions, IGM believes it can extend its current cash runway into 2027. Corporate Updates As part of the Company’s strategic pivot to autoimmunity, Fred Schwarzer, Chief Executive Officer, President and Director, and Bruce Keyt, Ph.D., Chief Scientific Officer, will step down from their current roles at the Company. Both Mr. Schwarzer and Dr. Keyt are expected to remain as consultants.Chris Takimoto, M.D., Ph.D., F.A.C.P., Chief Medical Officer, is stepping down from his current role to pursue an opportunity outside the Company. “We deeply thank Fred and Bruce for their vision and leadership of IGM, for their many significant contributions to developing the field of IgM antibodies, and for expanding our understanding of their full clinical potential,” said Christina Topsøe, director at IGM Biosciences. “We also want to sincerely thank Chris for his leadership of the clinical development organization as it expanded beyond oncology. We wish each of them the best in their future endeavors.” Conference Call and WebcastThe Company will host a conference call and live webcast to provide an update on its strategic pivot to focus exclusively on the development of T cell engagers for autoimmunity at 4:30 p.m. EDT today, September 30, 2024.
