hTERT I540/R572Y/D988Y multipeptide vaccine
A peptide vaccine consisting of multiple epitopes derived from the human telomerase reverse transcriptase (hTERT), the catalytic subunit of human telomerase, with potential immunostimulating and antineoplastic activities. hTERT I540/R572Y/D988Y multipeptide vaccine contains strongly antigenic peptide epitopes I540 (9-mer), R572Y (9-mer) and D988Y (10-mer). Vaccination with this agent may elicit a cytotoxic T cell (CTL) response against telomerase-expressing tumor cells. Directly linked to tumorigenesis, telomerase is expressed in the majority of human cancer cells but is infrequently expressed in normal cells. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
