Phase Ia/Ib Trial of Anti-PSMA Designer T Cells in Advanced Prostate Cancer After Non-Myeloablative Conditioning
The study creates autologous gene-modified T cells against prostate specific membrane
antigen (PSMA, unrelated to PSA) (designer T cells) by ex vivo modification of patient T
cells. T cells are collected by leukopheresis, transported to the RWMC cGMP Cell
Manipulation Core and transduced with retrovirus containing a chimeric antigen receptor
(CAR) that is expressed on the modified cells. This CAR links specificity of an antibody
against PSMA with signaling domains of the T cell and redirects the recognition of the T
cells to engage and kill prostate cancer cells anywhere in the body. These are administered
at a dose of 10^10 with randomization to either low or moderate Interleukin 2 given by CI
(continuous infusion) for one month following the T cell infusion. Subsequent subjects will
receive 10^11 cells with Interleukin 2 at either low or moderate dose, in a non randomized
manner, depending upon the outcome of the prior cohort. Prior to T cell infusion, all
subjects will receive non-myeloablative (NMA) conditioning. This conditioning creates a
"space" in the blood and marrow for engraftment of the infused cells to maintain of high
level of anti-tumor effector T cells in the body. Each patient is treated with a single
dose of T cells, without repeat dosing. Patients are followed for toxicity and response and
pharmacokinetics-pharmacodynamics of the infused T cells. Patients are on-study for
one-month after their T cell dose.
