Press Release - June 27, 2017
Heidelberg, Germany, June 27, 2017 – Affimed N.V. (Nasdaq: AFMD), a clinical stage biopharmaceutical company focused on discovering and developing highly targeted cancer immunotherapies, announced today the presentation of preclinical data for the Company’s AFM24 and AFM26 programs at the EACR-AACR-SIC 2017 Special Conference in Florence, Italy.
“With our NK-cell engagers AFM24 and AFM26 we are pursuing two preclinical programs which we believe are ideally suited to exploit NK-cell mediated cytotoxicity to fight cancer,” said Dr. Martin Treder, Chief Scientific Officer of Affimed. “Our data for both programs show a well-differentiated profile from competitor products, addressing the need for higher efficacy and better safety.”
AFM24 and AFM26 are two first-in-class tetravalent, bispecific NK-cell engagers targeting CD16A, a dominant activating receptor on NK-cells. In addition, AFM24 targets EGFR, while AFM26 binds to BCMA. Corroborating the Company’s earlier data, the studies presented at EACR-AACR-SIC 2017 provided further evidence of favorable safety profiles for both NK-cell engagers and also confirmed their ability to potently and effectively lyse tumor cells, even those with very low target expression. Furthermore, the high affinity to CD16A on NK-cells, resulting in long cell retention binding to NK-cells, and the minimal influence of serum IgG on tumor cell lysis are important differentiating factors of Affimed’s NK-cell platform compared to IgG-based monoclonal antibodies (mAbs).
In detail, AFM24 was shown to be distinguished from cetuximab in vitro and in vivo through higher potency at both high and low EGFR expression levels and in RAS mutant cells, while offering a more favorable safety profile. Single and repeat dose toxicology studies in cynomolgus monkeys demonstrated that AFM24 was well-tolerated at high doses. Further differentiating AFM24 from other therapies, no evidence of skin toxicity, a side effect commonly seen for other anti-EGFR antibodies and for tyrosine kinase inhibitors, was observed.
In addition, the Company presented further data highlighting the preclinical progress of AFM26. The NK-cell engager was able to elicit efficient tumor cell lysis in both cell lines and primary cells, even at very low BCMA expression levels. In addition, the amount of inflammatory cytokines released in vitro by cells treated with AFM26 was markedly lower than those of cells treated with a BCMA/CD3 T-cell engager. Furthermore, in contrast to approved mAb therapies such as daratumumab and elotuzumab, AFM26 did not induce NK-cell depletion in vitro.
Taken together, the results presented at EACR-AACR-SIC 2017 support the therapeutic rationale of redirecting NK-cells to tumors through bispecific tetravalent NK-cell engagers, which offers a novel mode of action addressing limitations of other therapies.
