100% objective response rate with a 42% complete response rate in 12 patients, according to investigator assessment, after the 1st of 2 planned cycles at the recommended phase 2 dose of 108 cord blood-derived natural killer (cbNK) cells/kg pre-complexed with AFM13 No cases of serious adverse events such as cytokine release syndrome, neurotoxicity syndrome or graft-versus-host disease were observed Affimed to host virtual investor event on December 9th to discuss the results HEIDELBERG, Germany, Nov. 22, 2021 (GLOBE NEWSWIRE) -- Affimed N.V. (Nasdaq: AFMD), a clinical-stage immuno-oncology company committed to giving patients back their innate ability to fight cancer, today announced interim clinical results from the investigator-initiated phase 1-2 study at The University of Texas MD Anderson Cancer Center, evaluating cbNK cells pre-complexed with Affimed’s innate cell engager (ICE®) AFM13. As of October 31, 2021, a total of 18 patients with CD30-positive relapsed or refractory Hodgkin and non-Hodgkin lymphomas (16 and 2 patients, respectively) were treated with the novel combination of cbNK cells pre-complexed with AFM13. A treatment cycle consists of lymphodepleting chemotherapy with fludarabine and cyclophosphamide followed two days later by a single infusion of cytokine-preactivated and expanded cbNK cells that are pre-complexed with AFM13, followed by three weekly infusions of AFM13 (200 mg) monotherapy. Responses are assessed on day 28 by FDG-PET and patients can receive up to two cycles. Three patients were treated with 1x106, three patients with 1x107 and 12 patients with 1x108 AFM13-pre-complexed cbNK cells per kg body weight. As of the cutoff date, 16 of 18 patients had achieved an objective response to the treatment according to investigator assessment, with seven complete responses (CR) and nine partial responses (PR). Eleven of twelve patients treated at the recommended phase 2 dose level of 108 cbNK cells per kg had Hodgkin Lymphoma. In this cohort of patients treated at the recommended phase 2 dose, 100% responded after the first cycle of treatment with five CRs and seven PRs according to investigator assessment. Each of the patients in this cohort is eligible for a second treatment cycle, and updated data from this cohort will be reported at a later date. Treatment was well tolerated with five reported cases of transient infusion related reactions after the monotherapy infusions of AFM13. Of note, there were no instances of serious adverse events such as cytokine release syndrome, immune cell-associated neurotoxicity syndrome or graft-versus-host disease. “The patients enrolled in this study were all heavily pre-treated with a median of 6 lines of prior therapy and had progressive disease after their previous line of therapy,” said Dr. Andreas Harstrick, Chief Medical Officer at Affimed. “We are encouraged by the response rates that we continue to observe in these difficult to treat patients. The data are in line with data presented at AACR earlier this year. We also continue to see a very good safety pro the combination, which is important as many of these patients have been very heavily pretreated and cannot tolerate aggressive therapies. Combining our ICE® molecules with NK cells is an integral part of our strategy to bring innovative therapies to patients in need. We believe these preliminary data provide further validation of this approach.” Conference Call/Webcast Information Affimed will host a conference call and webcast on December 9th, 2021, at 8:30 a.m. EST to review the data. Affimed’s management will discuss the results to date, the current treatment landscape for CD30+ lymphomas, and next steps for the study. Dr. Yago L. Nieto, M.D., Ph.D, Department of Stem Cell Transplantation and Cellular Therapy, Division of Cancer Medicine from M.D Anderson Cancer Center will also be available during the call.

A live audio webcast of the conference call will be available in the “Webcasts” section on the “Investors” page of the Affimed website at or . A replay of the webcast will be accessible at the same link for 30 days following the call. About the Phase 1-2 Study The University of Texas MD Anderson Cancer Center is studying AFM13 in an investigator-initiated phase 1-2 trial in combination with cord blood-derived allogeneic NK cells in patients with recurrent or refractory CD30-positive lymphomas. The first phase of this study involves dose escalation of pre-complexed NK cells, with patients receiving lymphodepleting chemotherapy followed by 1×106 NK cells/kg in Cohort 1; 1×107 NK cells/kg in Cohort 2; and 1×108 NK cells/kg in Cohort 3. The trial is designed to explore safety and to determine the recommended phase 2 dose and evaluate its activity. The recommended phase 2 dose was determined as 1x108 NK cells/kg. In each cohort, the dose of the pre-complexed NK cells with AFM13 is followed by weekly doses of 200 mg AFM13 monotherapy for three weeks, with each patient evaluated for dose-limiting toxicities and responses on day 28. MD Anderson has an institutional financial conflict of interest with Affimed related to this research and has therefore implemented an Institutional Conflict of Interest Management and Monitoring Plan. Additional information about the study can be found at (NCT04074746). About AFM13 AFM13 is a first-in-class 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 is currently being evaluated as a monotherapy in a registration-directed trial in patients with relapsed/refractory peripheral T-cell lymphoma or transformed mycosis fungoides (REDIRECT). The study is actively recruiting. Additional details can be found at (NCT04101331). About Affimed N.V. Affimed (Nasdaq: AFMD) is a clinical-stage immuno-oncology company committed to give patients back their innate ability to fight cancer by actualizing the untapped potential of the innate immune system. The company’s proprietary ROCK® platform enables a tumor-targeted approach to recognize and kill a range of hematologic and solid tumors, enabling a broad pipeline of wholly owned and partnered single agent and combination therapy programs. The ROCK® platform predictably generates customized innate cell engager (ICE®) molecules, which use patients’ immune cells to destroy tumor cells.
