A Phase 1, First-in-Human, Dose-Escalation Study of MGD024, a CD123 x CD3 Bispecific Dart® Molecule, in Patients with Relapsed or Refractory CD123-Positive (+) Hematologic Malignancies () - Nov 29, 2022 - Abstract #ASH2022ASH_7276;

Of note, the CD123-directed therapy tagraxofusp has now become the standard of care (SoC) for blastic plasmacytoid dendritic cell neoplasm (BPDCN) (Pemmaraju NEJM 2019)...This new construct permits intermittent intravenous (IV) dosing due to a longer half-life (Alderson ASH 2021) compared with the first-generation DART molecule flotetuzumab, a continuous-infusion molecule that showed preliminary single-agent activity in refractory acute myeloid leukemia (AML) (Uy Blood 2021)...Secondary objectives include pharmacokinetics, immunogenicity, preliminary assessment of MGD024 clinical activity, and preliminary evaluation of safety/efficacy of tocilizumab in the management of MGD024-induced CRS...Response evaluation is determined using modified European LeukemiaNet (ELN) 2017 criteria for ALM and ALL; International Working Group (IWG) 2006 criteria for MDS; Lugano 2014 criteria for cHL; ELN 2020 criteria for CML; 2017 consensus criteria for HCL; IWG-Myeloproliferative Neoplasms Research and Treatment (MRT) & European Competence Network on Mastocytosis (ECNM) 2013 criteria for ASM; and modified criteria from Pemmaraju NEJM 2019 for BPDCN. Patients benefitting from MGD024 may continue to receive MGD024 after completion of the study treatment period, at physician discretion.

Combinatorial Anti-Tumor Activity in Animal Models of a Novel CD123 x CD3 Bispecific Dart® Molecule (MGD024) with Cytarabine, Venetoclax or Azacitidine Supports Combination Therapy in Acute Myeloid Leukemia (GWCC - Hall B5, Level 1) - Nov 5, 2021 - Abstract #ASH2021ASH_2723;
MGD024, however, achieved maximal cytolytic activity as flotetuzumab or RES234M1.1, albeit at increased concentrations. Similarly, MGD024 showed reduced potency in vivo against CD123-positive tumors compared to RES234M1.1; nevertheless, tumor growth reduction of the same magnitude as that observed with RES234M1.1 was attained at higher doses of MGD024 (0.5-1 mg/kg IV 2QW MGD024 vs.
