    SAFETY AND EFFICACY OF ANTICD20-CD3 BISPECIFIC T-CELL ENGAGING ANTIBODIES IN THE MANAGEMENT OF RELAPSED/REFRACTORY DIFFUSE LARGE B-CELL LYMPHOMA: A SYSTEMATIC REVIEW OF CLINICAL TRIALS (EHA 2023)
    In the trials, mosunetuzumab, glofitamab, epcoritamab, odronextamab, IGM-2323, and plamotamab were identified as antiCD20-CD3 bsAbs, which are evaluated against RRDLBCL as monotherapy and in combination regimens (Table). Based on our analysis , antiCD20-CD3 bsAbs are safe and efficacious. Among these drugs, glofitamab, epcoritamab and odronextamab as monotherapy and/or in combination regimens are the most effective therapies against RRDLBCL.

    DOSE RESPONSE PROFILE OF IGM-2323, A CD20XCD3 IGM BISPECIFIC T CELL ENGAGER, IN TRANSLATIONAL MODELS SUPPORTS PHASE 2 DOSE SELECTION IN NON-HODGKIN'S LYMPHOMA (EHA 2022)
    Conclusion IGM-2323 shows a bell-shaped dose versus response relationship preclinically, with high concentrations associated with reduced T cell activity. The in vitro data support the decision to move forward with our randomized Phase 2 design testing 100 mg and 300 mg dose levels in NHL patients.
