| Research Abstract |
I got start permission of an examination after I made acquisition (I pass authorization about Safety and Quality of HER2 peptide and finish approval in FDA), a vaccine therapy protocol by HER2 peptide from Australian LICR and submitted a clinical test application to Mie University Institutional Reviewer Board, and having discussed peptide for clinical test enough on applying HER2 peptide to Homo sapiens. Patient eligibility criteria was : 1) cancer notice was considered and being a cancer patient of HER2 positive, 2) HLA-A2402 maintainers, 3) resistant to standard therapy such as operations/chemotherapy/radiotherapy, and 4) enough informed consent decided to be provided. For the patient who satisfied eligibility criteria, I used a dose-escalation study of peptide and performed safety evaluation to observe a harmful phenomenon. HER2 positive ovarian cancer/breast cancer/lung cancer patient 10 in total were registered, but, in cancer vaccine clinical test, the harmful phenomenon was not accepted. Delay-related hypersensitivity reaction (DTH) was observed during an examination in one example, and DTH made it positive during the continuation dosage after the end in one example again. In addition, I understood that I could almost guide immune response for cancer in all examples in the cancer patient body by injecting HER2 peptide. Furthermore, I injected vaccine immunity more than six times repeatedly, and it understood that, in addition, it used GM-CSF together that immune reaction was strengthened. The tumor reduction effect had neither example by observation, but the cancer vaccine which I used HER2 peptide for was safe clinically without accepting a harmful phenomenon.
