At IGM Biosciences, we believe that real innovation comes from looking beyond current approaches to envision a better way to address disease.

Given the limitations of the widely used IgG antibody, we asked how we could use IgM antibodies, a naturally occurring, but different, class of antibody to help patients. We believe that an IgM could be a better antibody medicine that could be more effective at treating certain diseases.

Through tenacity, creativity, courage, and a decade of dedicated research, we have created unique IgM antibodies with high selectivity, affinity, and avidity that may redefine what is possible for therapeutic antibody medicines.

We have overcome various challenges to create these “super antibodies” and we intend to continue exploring new scientific boundaries and identifying how this new type of medicine can best be developed to provide new options and hope for patients, physicians, and caregivers.
