Brief Summary | The primary objective of this study is to verify the safety of antigen-specific T cells (CAR-T) and engineered immune effector cytotoxic T cells (EIE) modified by immunoregulatory genes and immune modified dendritic cell vaccine (DCvac) in the treatment of neurofibromatosis or schwannoma. | ||||
Detailed Description | Neurofibromatosis (NF) is caused by a genetic change that tends to develop benign tumors around nerves. NF is a lifelong condition that affects all populations equally, regardless of gender or ethnicity. Neurofibromatosis has been classified into three distinct types: NF1, NF2, and schwannomatosis. The hallmark tumors seen in NF2 are vestibular schwannomas, formerly known as acoustic neuromas. Vestibular schwannomas are benign tumors made up of abnormal Schwann cells, which are the cells that give the nerves the lining and insulation needed to conduct information. Vestibular schwannomas can cause hearing loss in one or both ears, depending on whether the tumors are unilateral or bilateral. Schwannomatosis is the same type of tumor as that of NF2 patients. Tumors are all related to Schwann cells. There is no cure for NF or schwannomatosis. Surgery is the only clinical method at present, and no drugs have been proved to be effective in the treatment of these tumors. Adoptive immunotherapy based on cytotoxic T lymphocytes reactive with specific antigens has proven to be effective. In vitro induction of tumor antigen-specific immune cells and engineering of target specific immune cells have great potential for cancer eradication. If CAR-T/CTL immunotherapy is effective, it is expected that Neurofibromatosis or Schwannomatosis tumors should shrink or disappear completely. However, the minimal residual tumor cells or cancer stem cells may exist and cause relapse to other tissues and organs. Follow-up immunotherapy must focus on enhancing the anti-tumor immunity. Therefore, this protocol includes follow-up application of DCvac to prevent recurrence. This study proposes a novel protocol of immunotherapy to evaluate the safety and effectiveness of targeting tumor antigens in patients. |
