About IGM Biosciences, Inc.

IGM Biosciences (Nasdaq: IGMS) is a clinical-stage biotechnology company committed to developing and delivering a new class of medicines to treat patients with cancer and autoimmune and inflammatory diseases. The Company’s pipeline of clinical and preclinical assets is based on the IgM antibody, which has 10 binding sites, compared to conventional IgG antibodies with only 2 binding sites. We have created unique IgM antibodies with high selectivity, affinity, and avidity that may redefine what is possible for therapeutic antibody medicines. We believe our proprietary IgM antibody technology platform is particularly well suited for developing T cell engagers and receptor cross-linking agonists. The Company also has an exclusive worldwide collaboration agreement with Sanofi to create, develop, manufacture, and commercialize IgM antibody agonists against oncology and immunology, and inflammation targets.

IgM Antibodies and Autoimmune and Inflammatory Diseases
Antibody treatments have revolutionized outcomes for patients with autoimmune and inflammatory diseases.  We are committed to exploring how the unique structure and binding properties of our IgM antibody platform can improve outcomes for patients with these serious conditions.
IgM Antibodies and Oncology
We are applying the power of avidity and the strong and durable binding of our IgM antibodies to create new treatment options for cancer patients. Our initial efforts in oncology are focused on the broad application of IgM antibodies to activate receptors to induce programmed death of cancer cells.
