  • Data Presented at AACR Virtual Annual Meeting II demonstrate that Affimed’s ROCK® platform has the ability to produce diverse Innate Cell Engagers for a multitude of hematologic and solid tumor cancers with consistent profiles in tumor lyses and safety
  • Data on both Affimed’s AFM24 (CD16A/EGFR) and Genentech’s RO797089 (CD16A/BCMA) show potent killing in tumor cell lines at low target expression in the relevant pre-clinical models
  • Both Innate Cell Engagers show dual Mode of Action through activation of CD16A on NK cells and macrophages, inducing ADCC and ADCP respectively
  • In cynomolgus monkeys both AFM24 and RO7297089 demonstrate a promising safety profile

Heidelberg, Germany, June 22, 2020 – Affimed N.V. (Nasdaq: AFMD), a clinical-stage immuno-oncology company committed to giving patients back their innate ability to fight cancer, today announced that data from two investigational Innate Cell Engagers (ICE) developed from its fit-for-purpose ROCK® platform were presented as posters at the American Association for Cancer Research (AACR) Virtual Annual Meeting II. Affimed researchers presented data on AFM24, a bispecific EGFR/CD16A ICE with the potential to overcome resistance to current targeted treatments for EGFR-positive malignancies. Researchers from Genentech, a member of the Roche Group, presented preclinical data on the pharmacology and safety of RO7297089, a novel anti-BCMA/CD16A bispecific antibody for the treatment of multiple myeloma built from the ROCK® platform; Affimed researchers contributed as co-authors on the poster.
“The data presented at AACR on AFM24 and RO7297089 further confirm the importance of activating the innate immune system to deliver transformative medicines to patients,” said Dr. Arndt Schottelius, Affimed’s Chief Scientific Officer. “Moreover, it is very exciting to see that both molecules show potent and targeted killing of tumor cells in vitro without high levels of cytokine release. With AFM24, we have already progressed to the 2nd dose cohort in our Phase 1/2A clinical study and very much look forward to seeing continued consistent safety profile and early signs of activity in future cohorts.“

AFM24 activates innate immunity to kill solid tumors, inducing both ADCC and ADCP

The data presented on Affimed’s AFM24 further elucidated its preclinical profile as a novel ICE that harnesses the innate immune system to induce potent tumor cell killing via ADCC and ADCP. Due to its distinctive mechanism of action (MOA), AFM24 is potentially eligible for treatment of EGFR-positive tumors, regardless of EGFR-pathway mutations and EGFR receptor density. Unlike other EGFR targeted therapies, EGFR is used as a docking site only, AFM24’s cytotoxicity is independent of EGFR functionality and the downstream signal cascade. The pre-clinical data suggest that AFM24 is well tolerated with no toxicity in cynomolgus monkeys. Based on its preclinical profile, AFM24 shows promising therapeutic benefit for a broad set of patients with hard-to-treat EGFR-expressing cancers. AFM24 is currently being studied in a Phase1/2A study.

RO7297089 shows potent cell killing of BCMA positive tumor cell lines employing NK cells and macrophages

The data presented on Genentech’s RO7297089 provided preclinical characterization of a novel BCMA/CD16A ICE, also based on the ROCK® platform, for the treatment of multiple myeloma. It was shown that RO7297089 is a potent therapeutic agent in vitro and selectively kills BCMA expressing multiple myeloma tumor cells by activating innate immunity (ADCC and ADCP). The in vitro assessment demonstrated that, unlike T cell redirecting therapies, RO7297089 is unlikely to have a risk of acute cytokine release. In a one-month repeat-dose study in cynomolgus monkeys, RO7297089 was well tolerated, and there were no test article-related adverse effects at up to 50 mg/kg, with no significant cytokine release. RO7297089 represents a novel and promising MOA with a favorable safety profile, distinct from the T cell-based BCMA-targeting modalities in the clinic.
