As the project partner, BLA Regulatory congratulates NKGen Biotech on receiving IND may proceed letter for allogeneic SNK02 project


Gaithersburg, MD (28 October 2022) – BLA Regulatory, LLC, a full-service biopharma regulatory consultancy, congratulates NKGen Biotech, Inc. on receiving US FDA IND may proceed letter for an allogeneic SNK02 to commence a Phase 1, open-label, dose-escalation study of its cryopreserved “off-the-shelf” allogeneic blood-derived NK cell therapy (SNK02) to evaluate safety and tolerability in participants with pathologically confirmed solid tumors refractory to standard of care therapy. 

About SNK02 

SNK02[1] may be the first cryopreserved allogeneic NK cell therapy that does not require lymphodepletion before administration unlike other cell therapies. Compared with the inhibitory mechanism of autologous NK cells, allogeneic NK cells have been shown to elicit potent antitumor efficacy due to induction of graft-versus-tumor effects[2,3,4]. The cryopreservation of NK cells can enable long-term storage of NK cells at medical facilities, allowing sufficient quantities of cells to be readily available for patients, thereby making allogeneic NK cell therapy to be more effective and practical[5].
