NCIt definition : A preparation of autologous T lymphocytes that have been transduced with a retroviral
vector expressing a chimeric antigen receptor (CAR) targeting alkaline phosphatase,
placental type (ALPP; placental alkaline phosphatase; PLAP), with potential immunostimulating
and antineoplastic activities. Upon infusion back into the patient, autologous anti-ALPP
CAR retroviral vector-transduced T cells target and bind to ALPP-expressing tumor
cells, thereby inducing selective toxicity in ALPP-expressing tumor cells. ALPP, mainly
expressed in placenta and testis, is overexpressed on certain tumor cell types, such
as on a proportion of colorectal cancers while not expressed in any other normal tissues.
It plays a key role in tumor cell proliferation.;
