Affimed Announces an ASCO Breakthrough Poster Presentation with Clinical Data of AFM24 in Combination with NKGen Biotech’s SNK01 NK Cells
- Positive clinical trial results for AFM24 in combination with SNK01. Stable disease observed in 3 out of 7 patients. No dose-limiting or unexpected toxicities observed.
- None.
- Stable disease was observed in three out of seven heavily pretreated patients
- No dose-limiting toxicities or unexpected toxicities were observed
HEIDELBERG, Germany, July 31, 2023 (GLOBE NEWSWIRE) -- Affimed N.V. (Nasdaq: AFMD) (“Affimed”, or the “Company”), a clinical-stage immuno-oncology company committed to giving patients back their innate ability to fight cancer, today announced that an abstract with clinical trial results of its innate cell engager (ICE®) AFM24 in combination with NKGen Biotech’s SNK01 (autologous non-genetically modified NK cells), has been accepted for a poster presentation at the ASCO Breakthrough conference from 3-5 August 2023 in Yokohama, Japan. The presentation includes dose escalation phase data on safety and efficacy of the phase 1 study in patients with advanced or metastatic EGFR-expressing solid tumors (NCT05099549).
As of June 2023, seven patients with a mean number of five prior therapies received the combination of AFM24 and SNK01. No unexpected or dose-limiting toxicities were observed, and the PK properties were similar to AFM24 monotherapy. The best objective response was stable disease in three out of the seven patients, including patients with heavily pretreated microsatellite stable colorectal cancer (MSS CRC).
“The poster at ASCO Breakthrough is the first clinical presentation of a bispecific NK cell engager in combination with autologous NK cells,” said Dr. Anthony El-Khoueiry, Associate Director of Clinical Research and Phase I Program Director at the USC Norris Comprehensive Cancer Center and principal investigator of the AFM24 studies. “Our data establish the feasibility of this novel combinatorial approach; the stabilization of disease in heavily pre-treated patients with microsatellite stable colorectal cancer was clinically meaningful.”
“The data presented provide proof-of-concept for the combination of AFM24 with NK cells with good tolerability,” said Dr. Andreas Harstrick, Chief Medical Officer at Affimed. “Despite this, Affimed and NKGen Biotech mutually decided to discontinue the presented study. In line with Affimed’s NK cell combination experience for AFM13, Affimed is currently evaluating the best option to advance AFM24 with an allogeneic off-the-shelf NK cell product.”
Details of the poster presentation are as follows:

About AFM24
AFM24 is a tetravalent, bispecific innate cell engager (ICE®) that activates the innate immune system by binding to CD16A on innate immune cells and EGFR, a protein widely expressed on solid tumors, to kill cancer cells. Generated by Affimed’s fit-for-purpose ROCK® platform, AFM24 represents a distinctive mechanism of action that uses EGFR as a docking site to engage innate immune cells for tumor cell killing through antibody-dependent cellular cytotoxicity and antibody-dependent cellular phagocytosis.
Affimed is evaluating AFM24 as monotherapy and in combinations with other cancer treatments in patients with advanced EGFR-expressing solid malignancies whose disease has progressed after treatment with previous anticancer therapies.
AFM24-101, a monotherapy, first-in-human phase 1/2a open-label, is a non-randomized, multi-center, multiple ascending dose escalation and expansion study. Additional details may be found at www.clinicaltrials.gov using the identifier NCT04259450.
AFM24 is also being evaluated in a phase 1/2a study in combination with Roche’s PD-L1 checkpoint inhibitor atezolizumab (AFM24-102, NCT05109442).
Furthermore, Affimed and NKGen Biotech are investigating AFM24 in combination with NKGen Biotech’s NK cell SNK01 in a phase 1/2a study (AFM24-SNK01-103, NCT05099549).
Based on the totality of the data accumulated for AFM24, the Company has decided to focus AFM24’s near-term development on advancing AFM24 in combination with checkpoint inhibitors. Affimed is also evaluating options for a combination of AFM24 with an allogeneic off-the-shelf NK cell product which the Company expects to be well suited for heavily pretreated patient populations.
