Virus-specific Activated T Lymphocytes From a Donor in Hematopoietic Progenitor Transplanted Patients

Brief description of study

Marrow transplanted immunocompromised patients with cytomegalovirus (CMV) viral infection will be treated with CMV activated T-Lymphocytes. T-Lymphocytes will be obtained through an apheresis from a compatible donor.

Safety and immunoreconstitution parameters in blood samples will be assessed up to +60 days after the treatment.

Detailed Study Description

A prospective, multicentre, open-label and uncontrolled phase Ib-II clinical trial in which a total of 20 patients 1 year of age with an allogeneic transplant of hematopoietic progenitors and post-transplant CMV infection will be included. The main objective is to evaluate the safety of the infusion of CMV activated T-lymphocytes and secondary objectives are to evaluate the efficacy through clinical evolution, viral load, ability to induce immunoreconstitution against the virus and evaluation of the persistence of specific T cells.

The treatment will be administered intravenously (central or peripheral route) in a single dose at a dose of 0.01-5 E4 specific virus T lymphocytes per Kg of receptor weight. After the infusion, patients will follow periodic controls (+7, +14, +21, +28, +45 and +60 days) in which a clinical evaluation will be performed and blood samples will be obtained in order to evaluate the persistence of specific T cells in the recipient:
