摘要: A phase I clinical trial was conducted to determine the safety of Telomelysin, a human telomerase reverse transcriptase (hTERT) promoter driven modified oncolytic adenovirus, in patients with advanced solid tumors. single intratumoral injection (IT) Telomelysin administered three cohorts (1 × 1010, 1 1011, 1012 viral particles). Safety, response and pharmacodynamics were evaluated. Sixteen variety tumors enrolled. IT well tolerated at all dose levels. Common grade 2 toxicities included site reactions (pain, induration) systemic (fever, chills). hTERT expression demonstrated biopsy 9 12 patients. Viral DNA transiently detected plasma 13 16 detectable four or sputum day 7 14 post-treatment despite below levels 24 h, suggesting replication. One patient had partial injected malignant lesion. Seven fulfilled Response Evaluation Criteria Solid Tumors (RECIST) definition for stable disease 56 after treatment. tolerated. Evidence antitumor activity suggested.
