Athenex, Texas Children’s Cancer Center, and the Center for Cell and Gene Therapy at Baylor College of Medicine Present New Clinical Data on GD2 CAR-NKT Cells in Neuroblastoma at ASGCT Annual Meeting
- Data presented by investigators from the Texas Children’s Cancer Center
- One PR, one CR and four SDs out of 11 patients enrolled
- GD2 CAR NKT cells were well tolerated with no dose limiting toxicities
- CAR-NKT AUC normalized to disease burden (AUC/Curie score) was associated with response to therapy.
Observed responses to date in 11 evaluable, heavily pretreated patients with neuroblastoma, include one complete response (CR) and one partial response (PR). Four additional patients have exhibited stable disease (SD). The durations of response for the CR and PR were approximately 5 and 3 months, respectively. No patients experienced grade 2 or higher toxicities related to the GD2-CAR NKTs. Post-treatment tumor biopsies showed GD2-CAR NKTs homing to metastatic lesions at all dose levels. The CAR-NKT AUC normalized to disease burden (AUC/Curie score using
“The results of the ongoing phase I study further validate the clinical activity of CAR-NKT cells,” said Dr.

“We are encouraged by the reassuring safety profile, expansion/persistence/tumor trafficking parameters and by the evidence of clinical activity with autologous, engineered CAR-NKT cell therapy at relatively low doses,” said Dr. Heczey, Associate Professor of Pediatrics – Oncology at
KUR-501 is an autologous product in which NKT cells are engineered with a CAR targeting GD2, which is expressed on almost all neuroblastoma tumors, as well as other malignancies. KUR-501 is being tested in the phase 1 GINAKIT2 clinical study (NCT03294954) in patients with R/R high risk neuroblastoma. The single-arm study will evaluate six dose levels of KUR-501 with patients receiving pre-dose lymphodepletion chemotherapy consisting of cyclophosphamide and fludarabine.
Neuroblastoma is a pediatric cancer and patients with R/R high risk neuroblastoma have a poor prognosis and a significant unmet medical need. The KUR-501 development program is also designed to provide autologous proof-of-concept for CAR-NKT cells in solid tumors using a validated target.
The GINAKIT2 study is supported by
