“We look forward to presenting clinical and biomarker results for flotetuzumab in patients with relapsed or refractory acute myeloid leukemia at the 2020 ASH annual meeting,” said Scott Koenig, M.D., Ph.D., President and CEO of MacroGenics. “The first of our two oral presentations will address results of the role of immune senescence and exhaustion-related RNA profiles in predicting outcomes in AML. The second oral presentation will provide the results on the use of flotetuzumab as salvage therapy in AML patients who failed induction therapy or experienced an early relapse. Together with our four posters, these presentations add to the growing medical and scientific interest in the potential of flotetuzumab in AML. Finally, we are very pleased to present data from the cohort of diffuse large B-cell lymphoma (DLBCL) patients who were treated in the dose expansion study of tebotelimab.”

Flotetuzumab (also known as MGD006) is a clinical-stage bispecific, investigational DART molecule that recognizes both CD123 and CD3. CD123, the interleukin-3 receptor alpha chain, has been reported to be over-expressed on malignant cells in AML and other hematologic malignancies. The primary mechanism of action of flotetuzumab is believed to be its ability to redirect T lymphocytes to kill CD123-expressing cells. To achieve this, the DART molecule combines a portion of an antibody recognizing CD3, an activating molecule expressed by T cells, with an arm that recognizes CD123 on the target cells. MacroGenics is conducting a single-arm, registration-enabling clinical study to evaluate flotetuzumab in up to 200 patients with primary induction failure / early relapse (PIF/ER) AML, with complete remission (CR) and CR with partial hematological recovery (CRh) as the primary endpoint. The study will be conducted as a continuation of the ongoing Phase 1/2 study (NCT02152956). The FDA has granted orphan drug designation to flotetuzumab for the treatment of AML.
Tebotelimab (also known as MGD013) is a clinical-stage bispecific, investigational DART molecule designed to independently or coordinately block PD-1 and LAG-3 checkpoint molecules to sustain or restore the function of exhausted T cells for the treatment of cancer. Data from the Phase 1 dose escalation study in cohorts of patients with advanced solid tumors at escalating flat doses of 1-1200 mg every two weeks were presented at the
