Clinical development of imvotamab (IGM-2323) advances. IGM continues to advance the clinical development of imvotamab, the Company’s novel IgM T cell engaging bispecific antibody, and continues to enroll patients in two Phase 2 clinical trials to assess the safety and efficacy of two doses, 100 mg and 300 mg, in patients with relapsed and/or refractory diffuse large B cell lymphoma and follicular lymphoma. IGM expects to provide an initial Phase 2 efficacy and safety update later this year or in the first quarter of 2023.
