Kuur Therapeutics, a leader in the development of off-the-shelf CAR-NKT cell immunotherapies for the treatment of solid and hematological malignancies, today announced the publication in Nature Medicine of interim findings from its ongoing phase 1 GINAKIT2 clinical trial collaboration with Baylor College of Medicine and Texas Children’s Hospital, in high risk relapsed refractory (R/R) patients with neuroblastoma, a form of childhood cancer.
The interim results demonstrated that expressing the CAR with interlukin-15 (IL-15), a natural protein that supports NKT survival, enhanced the tumor-fighting capabilities and in vivo persistence of autologous NKT cells. Two of three patients studied showed tumor reduction following CAR-NKT infusion: one classified as stable disease and the other as a partial response. Imaging revealed a dramatic reduction in the size and metabolic activity of bone metastases in the patient with the partial response. CAR-NKT cells demonstrated a favorable safety profile and localized to the site of the
