ET140203 T Cells in Pediatric Subjects With Hepatoblastoma, HCN-NOS, or Hepatocellular Carcinoma
brief summary
Open-label, dose escalation, multi-center, Phase I/II clinical trial to assess the safety/tolerability and determine the recommended Phase II Dose (RP2D) of ET140203 T-cells in pediatric subjects who are AFP-positive/HLA-A2-positive and have relapsed/refractory HB, HCN-NOS, or HCC.
detailed description
The trial starts with a dose escalation phase. A traditional dose escalation model (3+3) design will be used to determine the recommended phase II dose (RP2D). Subjects will then be treated at the RP2D in the expansion phase of the trial.
Following treatment, tumor response assessments will be performed at Months 1, 3, 6, 9, 12, 18, and 24. At each tumor response assessment visit, imaging will be performed (triphasic CT Scan) and used for response evaluation. Serum AFP levels will also be measured at each tumor response assessment visit.
The active assessment phase of the study will continue for 2 years. Subjects will be followed for 15 years post-treatment for assessment of treatment safety and overall survival.
