cbNK cells pre-complexed with engager is safe and CAR like.

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.
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.
100% objective response rate (ORR) was observed with a 42% CR rate in 12 patients with Hodgkin Lymphoma, after the 1st of 2 planned cycles at the recommended phase 2 dose of 108 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.
Treatment was well tolerated with five reported cases of transient infusion related reactions after the monotherapy infusions of AFM13.
