Using Gene Modified Neuroblastoma Cells for the Treatment of Relapsed/Refractory Neuroblastoma

"The first two injections will be given at week 1 and week 2 (i.e., separated by one week). Patients will then have a two-week rest and the remaining two injections will be given (again separated by one week) at week 4 and week 5.~A complete evaluation for evidence of toxicity and response will be performed at week 8 (after a 3 week rest).~At the 8 week (month 2) evaluation, in the absence of progressive disease requiring therapy without excessive toxicity and if more transduced cells are available, the patient will have the option to receive four additional SC injections each separated by 1 month at the higher of the two dosage levels they originally received."
