Affimed Announces Positive Results Demonstrating Safety and Efficacy of Acimtamig and AlloNK® Combination in Relapsed/Refractory Classical Hodgkin Lymphoma (R/R cHL) Patients

• The combination of acimtamig with AlloNK^® demonstrated an overall response rate of 86% and complete response of 55% in 22 heavily pretreated patients with R/R cHL, who have exhausted all standard of care treatments
• The combination showed a well-manageable safety profile with no unexpected safety signals

MANNHEIM, Germany, Dec. 08, 2024 (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, today announced the presentation of data in a poster session at the 66th ASH Annual Meeting and Exposition. The dataset includes 22 patients from the run-in phase of the LuminICE-203 (AFM13-203) phase 2 open-label, multicenter, multi-cohort study. The trial evaluates the safety and efficacy of the combination of acimtamig (AFM13) with Artiva Biotherapeutics’ allogeneic NK cell AlloNK^® in patients with R/R cHL.

Acimtamig in combination with AlloNK^® demonstrated a high overall response rate (ORR) of 86% with complete response (CR) of 55%. All patients in the study were heavily pretreated with a median of 5 (range: 2-13) prior therapies. All patients had received intensive combination chemotherapy, PD(L)1 checkpoint inhibitors and brentuximab vedotin. In addition, about two third of the patients had also received a previous stem cell transplant. The combination regimen exhibited a well-managed safety profile with no unexpected safety signals. Importantly, no cases of graft-versus-host disease (GvHD) or immune effector cell-associated neurotoxicity syndrome (ICANS) were reported.

“We are excited to present this new data, which highlights the significant potential of acimtamig combined with AlloNK^® as a highly effective, innovative treatment option for patients with R/R cHL,” said Dr. Andreas Harstrick, Chief Medical Officer of Affimed. “There are no established treatment options for patients with R/R cHL who have failed combination chemotherapy, PD(L)1 and brentuximab vedotin. To see more than 50% of patients achieving a complete response is extremely encouraging and highlights the potential that this combination may provide an effective treatment option for these refractory patients. It is also important that these data were obtained in a multicenter trial with 10 sites across the U.S. enrolling patients.”

These findings are in line with previous data generated from the single center investigator-initiated study AFM13-104 (NCT04074746), which utilized fresh allogeneic NK cells precomplexed with acimtamig in a similar R/R cHL patient population. These results further validate the co-administration approach of acimtamig with an off-the-shelf, allogeneic, cryopreserved NK cell product (AlloNK^®) in a multi-center setting. Enrolment into the LuminICE-203 trial is ongoing.

About Acimtamig

Acimtamig (AFM13) is a first-in-class ICE^® that uniquely activates the innate immune system to destroy CD30-positive hematologic tumors. Acimtamig induces specific and selective killing of CD30-positive tumor cells, leveraging the power of the innate immune system by engaging and activating natural killer (NK) cells and macrophages. Acimtamig is a tetravalent bispecific innate cell engager designed to act as a bridge between the innate immune cells and the tumor, creating the necessary proximity for the innate immune cells to destroy the tumor cells.

About LuminICE-203 (AFM13-203)

LuminICE-203 (AFM13-203) is a Phase 2 open-label, multicenter, multi-cohort study. The trial is evaluating the safety and efficacy of the combination of acimtamig (AFM13) with Artiva Biotherapeutics’ allogeneic NK cell AlloNK^® (AB-101) in patients with relapsed/refractory classical Hodgkin lymphoma and CD30-positive peripheral T cell lymphoma (NCT05883449).

The study builds on the unprecedented efficacy results from an investigator sponsored study, AFM13-104, which investigated acimtamig in combination with cord blood-derived NK cells in patients with refractory/recurrent CD30-positive Hodgkin or non-Hodgkin lymphoma (NCT04074746).

About Affimed N.V.

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.
