virus specific cytotoxic t-lymphocytes (ctls) for refractory cytomegalovirus (cmv)

Conditions: Cytomegalovirus Infections; Primary Immune Deficiency Disorder

Summary: cmv cytotoxic t cells (ctls) manufactured with the miltenyi clinimacs prodigy cytokine capture system will be administered in children, adolescents and young adults (caya) with refractory cytomegalovirus (cmv) infection post allogeneic hematopoietic stem cell transplantation (allohsct), with primary immunodeficiencies (pid) or post solid organ transplant. funding source: fda oopd


Eligibility criteria:
