MOUNTAIN VIEW, Calif., May 06, 2021 (GLOBE NEWSWIRE) —  IGM Biosciences, Inc. (Nasdaq: IGMS), a clinical-stage biotechnology company focused on creating and developing engineered IgM antibodies, today announced its financial results for the first quarter ended March 31, 2021 and provided an update on recent developments.

“We are very pleased with the progress we made in the first quarter towards achieving our clinical and pipeline goals for 2021,” said Fred Schwarzer, Chief Executive Officer of IGM Biosciences. “We look forward to announcing a recommended Phase 2 dose for IGM-2323, presenting initial data from the dose escalation portion of the Phase 1 trial of IGM-8444 and filing an IND for IGM-7354 during 2021.”
Pipeline Updates


  • Recommended Phase 2 dose expected in 2021. IGM continues to advance the clinical development of IGM-2323, the Company’s IgM-based CD20 x CD3 bispecific antibody, for the treatment of non-Hodgkin’s lymphoma (NHL) and potentially other CD20-expressing hematologic malignancies, including chronic lymphocytic leukemia (CLL). IGM has cleared the titration dose cohorts of 50/100 mgs, 50/300 mgs and 50/600 mgs in the ongoing Phase 1 clinical trial of IGM-2323, and is currently enrolling patients in what is expected to be its top titration dose cohort, 50/1000 mgs. IGM is also currently enrolling patients in the expansion dose cohorts of 50/100 mgs, 50/300 mgs and 50/600 mgs. IGM expects to complete enrollment in the dose escalation portion of the Phase 1 clinical trial and select a recommended Phase 2 dose in 2021.


  • Phase 1 data expected in the second half of 2021. IGM also continues to advance the clinical development of IGM-8444, the Company’s IgM Death Receptor 5 (DR5) agonist, for the treatment of a potentially broad range of solid tumors and hematologic malignancies. IGM has cleared its second dose escalation dose cohort, 1 mg/kg, in the ongoing Phase 1 trial, and is currently dosing patients in its third dose escalation cohort, 3 mg/kg, with every two week dosing. IGM has also begun dosing patients in its first combination with FOLFIRI dose cohort and its first weekly dosing cohort. IGM expects to report initial data from the dose escalation portion of the Phase 1 trial in the second half of 2021. 
  • Clinical testing of birinapant in combination with IGM-8444 expected to begin this year. As previously announced, during the first quarter of 2021, IGM entered into an exclusive license agreement with Medivir AB, by which IGM received global, exclusive development and commercialization rights for birinapant. IGM remains on track to begin clinical testing of birinapant in combination with IGM-8444 this year.


  • Investigational New Drug (IND) application expected to be filed this year. IGM also plans to file an IND application with the U.S. Food and Drug Administration (FDA) for IGM-7354, the Company’s IL-15 x PD-L1 bispecific IgM antibody, before the end of 2021 in order to begin clinical testing initially in solid tumors, followed by hematologic malignancies.

Corporate Updates

  • George Gauthier appointed to the newly created position of Chief Commercial Officer. Mr. Gauthier brings twenty years of experience in global commercial strategy, marketing and product development. Most recently, Mr. Gauthier was Vice President of Global Product Strategy for Breast and Gynecological Cancers at Genentech, where he led a global team in the creation and execution of commercial and product development strategies.
