Under the agreement, CiMaas will provide CYTEA BIO with the GMP-grade K562-F012 feeder cells for the expansion of its umbilical cord blood-derived NK cells. Conversely, CYTEA BIO will supply CiMaas with Pin™ antibodies for the pre-arming of CiMaas NK cells to assess the benefit it brings and the opportunity to pursue a longer-term partnership.
