- AFM24-101 phase 1/2 results in 10 patients from the non-small cell lung cancer (NSCLC) cohort demonstrated clinical activity and a well-managed safety profile in heavily pretreated patients with EGFR mutant NSCLC; updated interim analysis data of 15 patients from the NSCLC cohort will be presented at ASCO on June 3, 2023
- AFM24-101 phase 1/2 interim results from the colorectal cancer (CRC) cohort show AFM24 was well tolerated in heavily pretreated patients with EGFR positive CRC
HEIDELBERG, Germany I May 25, 2023 I 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 the publication of two abstracts with its innate cell engager (ICE®) AFM24 in advance of the American Society of Clinical Oncology (ASCO) Annual Meeting, taking place on June 2 - 6, 2023 in Chicago, IL.
As of the December cut-off data for the abstract, 14 patients were enrolled in the EGFR mutant NSCLC cohort and the best objective response in 10 evaluable patients was a confirmed partial response in 1 patient (change from baseline -45%); 4 patients exhibited stable disease of which two had tumor shrinkage. AFM24 exhibited a well-managed safety profile and the most common treatment-related adverse events (TRAE) observed were mild to moderate infusion-related reactions (IRRs).
Updated data with a cut-off date of mid-April 2023 will be presented by Dr. Anthony El-Khoueiry, Associate Director of Clinical Research at USC Norris Comprehensive Cancer Center, at ASCO on June 3, 2023 during the poster session on Developmental Therapeutics – Immunotherapy (8:00 - 11:00 a.m. CDT). Dr. El-Khoueiry’s presentation will include data from 15 evaluable patients.
“The data we are generating in this study and our ongoing combination studies will guide our decisions in identifying the right indications and treatment regimens in which AFM24 can provide the most value for patients. We are encouraged to see clinical activity with AFM24 monotherapy in highly advanced NSCLC patients who have failed prior lines of therapy,” said Dr. Andreas Harstrick, Chief Medical Officer at Affimed. “These data show that our mechanism of targeting NK cells is biologically relevant in the quest to find innovative treatment strategies for patients suffering from difficult to treat solid tumors. We look forward to providing an update on our strategic development plan for AFM24 at ASCO.”
As of the December cut-off date, 16 patients with Stage 4 CRC were enrolled and treated with AFM24 with a median treatment duration of 5.1 weeks. No objective responses were observed. Seven patients remained on treatment as of the cut-off date, including 1 patient with confirmed stable disease ongoing for 5 months exhibiting a tumor reduction of 17%. Treatment was adequately tolerated with IRRs being the most common TRAEs.

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 (AFM24-103, NCT05099549).
