On March 10, 2021 Affimed N.V. (Nasdaq: AFMD), a clinical-stage immuno-oncology company committed to giving patients back their innate ability to fight cancer, reported its decision to continue enrollment in the REDIRECT trial, which is evaluating AFM13 as a monotherapy for the treatment of patients with relapsed or refractory CD30-positive peripheral T-cell lymphoma (PTCL) (Press release, Affimed, MAR 10, 2021, View Source [SID1234576410]).

The decision to continue the trial followed a preplanned interim futility analysis. The interim analysis was triggered following enrollment of 20 patients in both Cohort A (³10% CD30) and Cohort B (>1% to <10% CD30). The futility boundary was derived from response rates for previous therapies that have received accelerated approval in relapsed or refractory (R/R) PTCL. The futility analysis demonstrated that the response rate in Cohort A achieved the predefined threshold for continuation of the study. The response rate in Cohort B was sufficiently comparable to allow merging of both cohorts into a single cohort for all patients with CD30 >1%, per the study protocol. Evidence of anti-tumor response was observed in both cohorts with complete and partial responses. The safety analysis was consistent with previously reported data from Affimed’s Phase 1 trials of AFM13, with infusion related reactions (IRRs) representing the main side effect. Following the introduction of mandatory premedication, IRRs were markedly reduced, resulting in fewer dose reductions and a trend towards better activity.
"We are very encouraged by the observed activity of AFM13 in this heavily pretreated patient population, where more than half of the patients had three or more lines of previous therapy. These data reinforce our strategy to broadly develop AFM13 across CD30-positive lymphomas both as monotherapy and in combination with other therapies," said Dr. Andreas Harstrick, Affimed’s Chief Medical Officer. "Having successfully met the criteria for continuation, the trial will move forward by merging the CD30 high- and low-expressing PTCL cohorts for evaluation of the safety and efficacy of AFM13."
"We are excited by this progress and by AFM13’s potential as monotherapy for patients with PTCL," said Dr. Won Seog Kim, Principal Investigator of REDIRECT and Professor of Hematology and Oncology at the Samsung Medical Center, Sungkyunkwan University, Seoul, Korea. "PTCL is an aggressive and challenging cancer to treat in patients who relapse or do not respond favorably to current therapies, which often have high toxicity profiles, and new therapeutic approaches are needed."
AFM13 is also being evaluated in combination with cord-blood derived natural killer cells in CD30-positive lymphomas at MD Anderson Cancer Center (MDACC). Initial data from this investigator sponsored study will be presented at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting in April 2021.

About AFM13-202 and the REDIRECT Trial Design
REDIRECT (also known as AFM13-202, NCT04101331) is a registration-directed phase 2 open-label, multicenter, global study investigating the efficacy and safety of AFM13 monotherapy in patients with R/R CD30-positive PTCL and Transformed Mycosis Fungoides (TMF).
The study enrolls patients who suffer from CD30 expressing PTCL or TMF and who have relapsed after an earlier standard of care treatment or have refractory disease. Dependent on their disease type and the magnitude of CD30 expression on their tumor cells, study participants are assigned to one of three study cohorts, each cohort receiving the same treatment of weekly AFM13 infusions (a 200mg dose per infusion). The three cohorts are comprised of Cohort A, which includes PTCL patients with ³10% CD30 expression on tumor cells; Cohort B, which includes PTCL patients with >1% to< 10% CD30 expression on tumor cells; and, Cohort C, currently on hold, which includes TMF patients with ³1% CD30 expression on tumor cells.
The main goal of the study is to assess the efficacy of AFM13 treatment as judged by the rate of objective responses. Further goals of the study are to assess the safety of AFM13 treatment, the immunogenicity of AFM13 (as measured by the formation of anti-AFM13 antibodies) and the concentration of AFM13 in the blood.
The study began recruitment in October 2019 at sites in the United States, Australia, South Korea and seven European countries. The TMF arm of the study (Cohort C), which is exploratory only and not relevant to the potential consideration for accelerated approval, will remain paused, due to COVID-19 and the high number of assessments and site visits necessary for this group of patients. To date, no TMF patients have been recruited into the study.
