About

Multiple Myeloma (MM) is a lethal disease and at present no available treatment method seems to prevent the disease from progressing or relapsing in the long term. NK cells have a relatively high cytotoxic capacity and an anti tumour effect, suggesting a potential as a treatment of MM.This is a phase I, first-in-human, therapeutic exploratory study, where no benefits for the patients can be guaranteed. However, the theoretical implication is that the infused cells may have a positive antitumour effect for the participating individuals.

Autologous NK cells

Experimental group

Description:

The investigation product is a cell suspension based on ex vivo expanded NK cells from patients with MM. The treatment is strictly autologous. The IP is given as three infusions with escalating doses. Mode of administration Intravenous infusions. Dose levels * First infusion; 5x10\^6 cells/kg body weight * Second infusion; 50x10\^6 cells/kg body weight * Third infusion; 100x10\^6 cells/kg body weight

Treatment:

Drug: autologous NK cells
