On May 23, 2023 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, reported that the U.S. Food and Drug Administration (FDA) has cleared its IND application for the combination of AFM13, its first-in-class tetravalent bispecific innate cell engager (ICE) and AB-101, Artiva Biotherapeutics Inc.’s ("Artiva") clinical-stage, cryopreserved, off-the shelf, non-genetically modified, allogeneic cord blood-derived natural killer (NK) cells to initiate the clinical trial, AFM13-203 (LuminICE-203) (Press release, Affimed, MAY 23, 2023, View Source [SID1234631974]). The phase 2 study will be an open-label, multi-center, multi-cohort study with a safety run-in followed by dose optimization and expansion phases. The study will evaluate the safety and efficacy of AFM13 in combination with AB-101 in patients with r/r cHL and CD30-positive PTCL. Affimed intends to initiate the study in the third quarter of 2023 and expects to report data from the safety run-in phase in the first half of 2024.

"We are excited to have received FDA clearance of our IND application for this promising combination therapy of AFM13 and AB-101, which has the potential to provide a new treatment option for Hodgkin Lymphoma and PTCL patients," said Wolfgang Fischer, Chief Operating Officer of Affimed. "We are very focused on getting the study up and running in the third quarter of 2023 and advancing it as quickly as possible."
"Despite recent advancements in the field that include promising targeted and immunological agents, there is still an unmet medical need for treatments in the r/r setting of classical Hodgkin Lymphoma," said Dr. Andreas Harstrick, Chief Medical Officer at Affimed. "Therapies like the combination of AFM13 with NK cells that enable patients to achieve complete responses have the potential to contribute to this benefit."
AFM13-203 (LuminICE-203) will build on data generated from the Company’s AFM13-104 study together with The University of Texas MD Anderson Cancer Center, which demonstrated the promise of AFM13 in combination with cord blood-derived NK (cbNK) cells for the treatment of r/r cHL and Non-Hodgkin lymphoma patients. Data from the AFM13-104 study, presented at the American Society of Hematology (ASH) (Free ASH Whitepaper) 2022, demonstrated a 94% ORR and a CR rate of 71% in 35 heavily pre-treated CD30-positive Hodgkin lymphoma (HL) and Non-Hodgkin lymphoma (NHL) patients treated at the recommended Phase 2 dose (RP2D). 63% of patients (n=24) treated at the RP2D with at least 6 months of follow-up after the initial infusion remained in CR for at least 6 months. In addition, the treatment was well tolerated with no cases of cytokine release syndrome, immune effector cell-associated neurotoxicity or graft versus host disease observed.
STUDY DETAILS
AFM13-203 (LuminICE-203) is a phase 2, open-label, multi-center, multi-cohort study with a safety run-in followed by dose optimization and expansion phases. Patients with a diagnosis of r/r cHL who will enroll in the study must have received at least two lines of therapy, including one prior line of combination chemotherapy. In addition, prior therapy must also have included brentuximab vedotin and a PD-1 checkpoint inhibitor.
The trial is designed to enroll up to 134 r/r cHL patients, including 24 patients in the safety run-in, and between 68 – 110 in the dose optimization and expansion phases. The study also includes an exploratory cohort comprised of an additional 20 PTCL patients.
During the IND process, Affimed requested FDA feedback on the suitability of the study to support an accelerated approval in cHL. At the recommendation of the FDA, in parallel to advancing the study, Affimed expects to have further discussions with the agency on the requirements for a registration application in the U.S.

About Classical Hodgkin Lymphoma
cHL is the most common CD30-positive lymphoma. cHL mainly results from the clonal transformation of cells of B-cell origin, giving rise to pathogenic Reed-Sternberg cells (RSCs). RSCs are most likely derived from germinal center B-cells that acquire unfavorable immunoglobulin V gene mutations and normally would undergo apoptosis. The characteristic large, often bi-nucleated RSCs are mixed with a cell infiltrate composed of variable proportions of lymphocytes, histiocytes, eosinophils, and plasma cells. Based on the mix of different cells in the histological assessment, four types of cHL are described: nodular sclerosing, mixed cellularity, lymphocyte rich and lymphocyte depleted.
About AFM13
AFM13 is a first-in-class tetravalent bispecific innate cell engager (ICE) that uniquely activates the innate immune system to destroy CD30-positive hematologic tumors. AFM13 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. AFM13 is Affimed’s most advanced ICE clinical program and was evaluated as monotherapy in a phase 2 trial in patients with relapsed/refractory peripheral T-cell lymphoma (REDIRECT, NCT04101331). In addition, The University of Texas MD Anderson Cancer Center is studying AFM13 in an investigator-sponsored Phase 1 trial in combination with cord blood-derived allogeneic NK cells in patients with recurrent or refractory CD30-positive lymphomas (NCT04074746). The company reported data from this study at ASH (Free ASH Whitepaper) 2022 annual meeting. To find out more about AFM13 and the studies, please visit: www.affimed.com.
About AB-101
AB-101 is Artiva’s non-genetically modified, cord blood-derived, allogeneic, cryopreserved, ADCC-enhancing NK cell therapy candidate for use in combination with monoclonal antibodies or innate-cell engagers in the out-patient setting. Artiva selects cord blood units with the high affinity variant of the receptor CD16 and a KIR-B haplotype for enhanced product activity. Using Artiva’s AlloNK platform, Artiva can generate thousands of doses of pure, cryopreserved, infusion-ready NK cells from a single umbilical cord blood unit while retaining high and consistent expression of CD16 and other tumor-engaging receptors, without the need for engineering.
Artiva is conducting a Phase 1/2 multicenter clinical trial (ClinicalTrials.gov Identifier: NCT04673617) to assess the safety and clinical activity of AB-101 alone and in combination with the anti-CD20 monoclonal antibody, rituximab, in patients with relapsed or refractory B-cell-non-Hodgkin lymphoma (B-NHL) who have progressed beyond two or more prior lines of therapy. This study is progressing at multiple clinical sites across the U.S., and AB-101 is administered weekly in the out-patient setting over one-month cycles and with up to four cycles to assess therapeutic efficacy and durability. Artiva will present data from the first-in-human phase 1/2 clinical trial of AB-101 in combination with rituximab in R/R non-Hodgkin lymphoma at the 2023 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting.
