MOUNTAIN VIEW, Calif., May 09, 2022 (GLOBE NEWSWIRE) -- IGM Biosciences, Inc. IGMS, a clinical-stage biotechnology company focused on creating and developing IgM antibodies, today announced its financial results for the first quarter ended March 31, 2022 and provided an update on recent developments.

"IGM took a major step in expanding the scope and support of our research pipeline of IgM antibodies with the recent closing of an exclusive worldwide collaboration agreement with Sanofi for the creation, research and development of agonist IgM antibodies against three oncology targets and three autoimmune/inflammation targets," said Fred Schwarzer, Chief Executive Officer of IGM Biosciences. "We have also made significant progress in the clinical development of our wholly-owned pipeline of IgM antibodies with the start of our two Phase 2 studies for our T cell bispecific antibody, IGM-2323, and the continuation of our Phase 1 trial of IGM-8444. In addition to continued progress in these ongoing clinical trials, we also expect to file INDs for our targeted IL-15 IgM antibody, IGM-7354, and our CD38 x CD3 bispecific IgM antibody, IGM-2644, this year."

Corporate Updates

• Closing of collaboration agreement with Sanofi. IGM announced that the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the HSR Act), has expired in connection with the Company's previously announced exclusive worldwide collaboration agreement with Sanofi. In connection with the closing of the collaboration agreement, Sanofi will pay IGM a $150 million upfront payment.
