IGM Biosciences Announces Six Presentations at the American Society for Cancer Research Annual Meeting 2023

MOUNTAIN VIEW, Calif., April 13, 2023 (GLOBE NEWSWIRE) -- IGM Biosciences, Inc. (Nasdaq: IGMS), a clinical-stage biotechnology company focused on creating and developing engineered IgM antibodies, today announced the presentation of six posters at the upcoming American Association for Cancer Research (AACR) Annual Meeting 2023, taking place in Orlando, Florida on April 14-19, 2023.

“We are proud to show the breadth and depth of our oncology pipeline at this year’s AACR meeting, as the emerging data from our clinical and pre-clinical efforts on IGM-8444, IGM-7354, IGM-2644, IGM-2537 and imvotamab continue to demonstrate the potential for encouraging anticancer activity coupled with favorable safety profiles,” said Chris Takimoto, M.D., Ph.D., F.A.C.P., Chief Medical Officer of IGM Biosciences. “Looking ahead, we look forward to continued dosing in our randomized clinical trial of IGM-8444 in combination with standard of care FOLFIRI chemotherapy and bevacizumab in second line metastatic colorectal cancer patients and in our initial clinical study of IGM-7354 in patients with solid tumors. We are also excited to be initiating clinical studies of IGM-2644, our CD38 x CD3 T cell engaging IgM antibody, which we hope will prove to be a safe and more potent form of anti-CD38 therapy for multiple myeloma, including for patients who have previously been treated with daratumumab. We look forward to providing continued updates on these exciting oncology programs.”
