養子細胞免疫療法によるサイトメガロウイルス感染症の予防 (INMUNOCELL)
抗CMVパイロット臨床試験:養子細胞免疫療法による造血前駆細胞のハプロ同一移植におけるサイトメガロウイルス感染症の予防
Cytomegalovirus (CMV) infection is a major cause of morbidity and mortality for recipients of allogeneic hematopoietic stem cell transplantation(HSCT). Recently, strategies based on immunotherapy adoptive cells (IAC) with anti-CMV Cytolitic T Lymphocytes (CMV-CTLs) has been incorporated to prevent or treat CMV after HSCT. The aim to study donor derived CMV-CTLs after haploidentical HSCT (HAPLO) as prophylaxis for CMV infection in transplant patients. CMV-CTLs will be administer at day 21 (+-7 days) post-HAPLO. CMV DNA levels with quantitative PCR will be weekly monitored.

詳細な説明
In HAPLO, CMV infection and disease are more frequent than in other type of HSCT, this is related to delayed immune reconstitution after transplant increasing post-transplant infectious complications. Approximately 60% of patients reactivated CMV infection after HAPLO and 15%, developed CMV disease afecting organs and causing the death of the patient in 8% of CMV disease cases.
If patient and donor are eligible, it will take 1x10^9 cells from donor leukapheresis. Donor cells will be selected and procesed by CliniMACs PRODIGY and after 12h it will obtain 7mL of CMV-CTLs. It will use 6mL of CMV-CTLs to infused a dose of 1x10^5 cells/kg in our patient. The donor derived CMV-CTL cells will be transfused into the patients' intravenous line. The patients will receive the dose of CMV-CTL cells when they are sero-positive for CMV-DNA 21 (+- 7 days) days after transplant.
The CMV-DNA levels will be monitored weekly for at least 100 days after the transplant. If after the initial dose of CMV-CTL cells the patient develops a viral infection, then the patient will receive treatment with anti-CMV comercial drugs.

実験的:CMV CTLs
1x10^5 CMV-CTLs/kg |
The donor derived cytomegalovirus specific T lymphocytes (CMV-CTL) will be transfused to the patients. The patients will receive CMV-CTL cells when their donors are sero-positive for CMV-DNA 21 days after transplant. The CMV-DNA levels will be monitored weekly for at least 100 days after the HAPLO. If after the initial dose of CMV-CTL cells the patient develops a viral infection, then they may be eligible to receive a CMV specific antiviral drug. |
