NCIt synonyms : VB10.16 Vaccine; DNA Vaccine VB10.16;
NCIt definition : A therapeutic DNA vaccine composed of three parts, one encodes the E6/E7 fusion protein
of human papillomavirus (HPV) type 16 (HPV16), the second is a dimerization entity
and the third part encodes a protein that specifically binds to antigen presenting
cells (APCs), with potential immunostimulating and antineoplastic activities. Upon
intramuscular administration, abipapogene suvaplasmid expresses HPV16 E6/7 and a protein
that targets receptors on APCs. Upon binding to APCs and subsequent internalization,
the APCs mature and the HPV16 E6/7 antigenic protein is presented by the APCs. This
attracts and stimulates B-lymphocytes, CD4-positive T-lymphocytes and elicits a cytotoxic
T-lymphocyte (CTL) response against cancer cells expressing HPV16-associated E6 and
E7 oncoproteins, which result in tumor cell lysis. HPV16 E6/7, a viral antigen, plays
a key role in the development of certain types of cancer.;
