The objective of this clinical trial is to assess the toxicity of activated and expanded NK cell immunotherapy after salvage chemotherapy in patients with relapsed or refractary acute lymphoblast leukemia/lymphoblast lymphoma (LLT). |
El objetivo de este estudio es determinar la seguridad de la inmunoterapia con células Natural Killer expandidas y activadas (NKAESs) tras quimioterapia de rescate en pacientes con leucemia aguda linfoblástica/linfoma linfoblástico (LLT) en recaída o refractariedad |
|
E.2.2 | Secondary objectives of the trial |
. Analyze incidence of episodes of febrile neutropenia, bacteremia, infections (viral and fungal), days of isolation, hematological recovery and days of hospitalization. . Assess rate of complete remission (cytomorphological and by criteria of "minimal residual disease") . Assess immune reconstitution of lymphocytes and cytotoxic activity of NK cells pre and post NKAES infusion |
Analizar la incidencia de episodios de neutropenia febril, bacteriemias, infecciones (víricas, fúngicas), días de aislamiento, recuperación hematológica e ingreso hospitalario. Evaluar la tasa de remisión completa (citomorfológica y por criterios de ?enfermedad mínima residual?) Evaluar la reconstitución inmune de poblaciones linfocitarias y la actividad citotóxica de las células NK pre y post infusión de NKAES. |
