Heidelberg, Germany, May 13, 2021 – Affimed N.V. (Nasdaq: AFMD), a clinical-stage immuno-oncology company committed to giving patients back their innate ability to fight cancer, announced today the publication of preclinical in vitro and in vivo research of its lead innate cell engager (ICE®), AFM13 (CD16A/CD30), combined with healthy donor-derived NK cells in Clinical Cancer Research. The preclinical data demonstrated that AFM13 strongly binds to NK cells, including cytokine-activated or cord blood-derived NK (cbNK) cells, resulting in enhanced tumor recognition and antibody-dependent cellular cytotoxicity (ADCC). The research was generated through a collaboration with The University of Texas MD Anderson Cancer Center and Washington University School of Medicine and supports use of AFM13 combined with NK cells as a promising therapy for CD30-positive hematological malignancies.
The preclinical data published in Clinical Cancer Research supported the Investigational New Drug (IND) application for the ongoing Phase I clinical study of AFM13 precomplexed with cytokine-preactivated cbNK cells followed by AFM13 monotherapy in patients with CD30-positive malignancies. Results of the Phase 1 study as of March 31, 2021, demonstrated an objective response rate of 100% (ORR=4/4; PR=2/4; CR=2/4) among the first patients enrolled who were all heavily pretreated. There were no observed events of cytokine release syndrome, neurotoxicity, or graft-versus-host disease. The study will progress to the higher dose cohorts with additional updates expected throughout this year.
The Leukemia & Lymphoma Society (LLS) supported Affimed’s earlier clinical studies of AFM13 through its Therapy Acceleration Program® (TAP), LLS’s strategic venture philanthropy funding initiative.
