The preliminary results from the phase 2 study investigating AFM24 in combination with the checkpoint inhibitor atezolizumab in patients with EGFR wild-type non-small cell lung cancer have been accepted for poster presentation at the 2024 Annual Meeting of the American Society of Clinical Oncology. The study is evaluating AFM24, Affimed N.V.’s innate cell engager (ICE®), in combination with atezolizumab, Roche’s checkpoint inhibitor, in patients with EGFR-wildtype (EGFRwt) non-small cell lung cancer (NSCLC). Details of the poster presentation are as follows: Title: Preliminary results from the phase 2 study of AFM24 in combination with atezolizumab in patients with EGFR wild-type (EGFR-WT) non-small cell lung cancer (NSCLC) Presenting Author: Hye Ryun Kim Poster Session: Developmental Therapeutics—Immunotherapy Abstract Number: 2522 Poster Presentation Time: Saturday, June 1, 2024, 9:00 a.m. – 12:00 p.m. CDT The full abstract will become available on ASCO’s website on May 23, 2024 at 5:00 p.m. (EDT).

AFM24 is a tetravalent, bispecific ICE® that activates the innate immune system by binding to CD16A on innate immune cells and epidermal growth factor receptors (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 (Nasdaq: AFMD) is a clinical-stage immuno-oncology company committed to giving patients back their innate ability to fight cancer by actualizing the untapped potential of the innate immune system. The Company’s innate cell engagers (ICE®) enable a tumor-targeted approach to recognize and kill a range of hematologic and solid tumors. ICE® are generated on the Company’s proprietary ROCK® platform which predictably generates customized molecules that leverage the power of innate immune cells to destroy tumor cells. A number of ICE® molecules are in clinical development, being studied as mono- or combination therapy. Headquartered in Mannheim, Germany, Affimed is led by an experienced team of biotechnology and pharmaceutical leaders united by the bold vision to stop cancer from ever derailing patients’ lives.
