MANNHEIM, Germany, Dec. 11, 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, announced interim safety and efficacy data on its innate cell engager (ICE^®) AFM24 from the ongoing AFM24-102 combination study with atezolizumab, an anti-PD-L1 checkpoint inhibitor, in patients with advanced EGFR-expressing solid tumors. The data update as of December 6^th, 2023, includes 15 patients from the EGFR-wildtype NSCLC cohort with a median of 2 prior lines of therapy. Importantly, all patients were pretreated with and ultimately progressed while on PD-[L]1 targeting therapy.

The combination of AFM24 with atezolizumab showed encouraging signals of clinical activity, including 1 unconfirmed CR, 3 PRs (1 confirmed, 2 unconfirmed) and 7 patients exhibiting SD. All eleven patients with a confirmed response, unconfirmed response or stable disease (73%) are continuing treatment, with 4 patients exceeding 3 months of therapy; 2 patients improved from SD at the first scan to PR at the second scan based on RECIST criteria.

“Most patients with advanced NSCLC will need additional treatment after first-line therapy, and currently available options for patients in the 2L+ setting provide only modest response rates and short progression-free survival,” said Dr. Andreas Harstrick, Chief Medical Officer at Affimed. “Given the severity of this cancer and the urgent need for new treatments, we are very encouraged by the early safety and efficacy results demonstrated by the combination of AFM24 and atezolizumab in this cohort. We look forward to seeing the data in this cohort mature as well as to sharing data from the EGFR-mutant NSCLC cohort, anticipated in the first half of 2024.”

Affimed’s ICE^® AFM24, in combination with atezolizumab, has the potential to reactivate the innate and consequently the adaptive immune system to recognize and destroy EGFR-positive NSCLC tumors. Considering the low ORR reported on atezolizumab monotherapy in checkpoint inhibitor-relapsing and refractory patients, Affimed believes the clinical activity observed in AFM24-102 is likely due to the synergy of AFM24 with atezolizumab.

AFM24 has demonstrated a positive safety and tolerability profile as both a monotherapy and in combination therapy. The combination with atezolizumab has not led to unexpected toxicity, and the toxicity observed to date is in line with the toxicity profile of the individual agents alone. The majority of patients experienced only mild to moderate treatment-related adverse events.

Affimed also announced that it has discontinued enrollment in AFM24-102 into the gastric cancer cohort and the basket cohort evaluating pancreatic cancer, biliary tract cancer and hepatocellular carcinoma. While clinical activity was observed in both cohorts, neither cohort is likely to achieve response rates that would meet the Company’s efficacy hurdle and the Company’s strategic focus is to advance the NSCLC program as fast as possible.

The conference call will be available via phone and webcast. The live audio webcast of the call will be available in the “Webcasts” section on the “Investors” page of the Affimed website at https://www.affimed.com/investors/webcasts-and-corporate-presentation/.

About the AFM24-102 Phase 1/2a Study

AFM24-102 is a Phase 1/2a open-label, non-randomized, multicenter, dose escalation, and expansion study evaluating AFM24 in combination with atezolizumab in patients with selected EGFR-expressing advanced solid malignancies whose disease has progressed after treatment with previous anticancer therapies (NCT05109442).

The Company also announced data from the phase 1/2 data study of acimtamig in combination with allogeneic NK in relapsed/refractory Hodgkin Lymphoma patients conducted at the University of Texas MD Anderson Cancer Center. The Company will host a call today at 1:30 p.m. PST / 4:30 p.m. EST / 22:30 CET to discuss both the acimtamig and AFM24 clinical data updates and to provide an update on the status of the acimtamig LuminICE-203 study.

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.

In addition to studying AMF24 in combination with the checkpoint inhibitor atezolizumab, Affimed is also evaluating options for a combination of AFM24 with an allogeneic off-the-shelf NK cell product that the Company expects to be well suited for heavily pretreated patient populations.
