Technology and Products

For its first project, Emercell is developing a generic cell immunotherapy NK-based to be used in synergy with monoclonal antibodies (MAbs) to treat refractory patients in oncology. This new and innovative drug therapy called NK-001 consists of allogeneic Natural Killer (NK) cells which are produced ex vivo according to a patented process.

NK lymphocytes present natural cytotoxicity and specific cytotoxicity in association with MAbs (Antibody-Dependent Cell Cytotoxicity (ADCC)) and are known for their natural immunology surveillance of cancers.

NK cells being considered as highly potent effectors, two NK-based therapeutic strategies exist:

  • Regulating endogenous NK activity, that needs sufficient quantities of properly activable NK cells.

  • Infusing exogenous NK cells to the patient for which full industrialization with production of frozen batches to treat several dozens of patients is rarely reached.

  • EMERCell NK-001 solution is an optimized active product, with low incidence of endogenous immune system state, consisting of highly activated & alloreactive allogeneic NK cells. The process allows full industrialization using the same source of NK cells for all patients, and producing high quantities of cells to treat dozens of patients with one batch.
