Outcome Measures
Primary Outcomes (1)
Number of Participants with Adverse Events as a Measure of Safety and Tolerability of intravenous allogeneic unrelated mesenchymal stem cells infusion in patients with severe acquired aplastic anemia.
Adverse events like allergic reactions,infectious diseases,organ dysfunction or other related to mesenchymal stem cells infusion will be assessed.
After the mesenchymal stem cells infusion up to 6 mounth after
Secondary Outcomes (3)
Level of cytopenias
weekly until 6 months
Transfusional requirements
weekly until 6 months
Incidence of infections and febrile neutropenia
weekly until 6 months
Interventions
After standard immunosuppressive therapy with rabbit antithymocyte globulin 3,5 mg/Kg/day during 5 days, allogeneic unrelated bone marrow derived mesenchymal stem cells will be infused intravenously. Oral cyclosporine 5 mg/Kg/day (with dose correction weekly to keep serum cyclosporine level between 150-250 mg/dl) up to 6 months will be added.
Eligibility Criteria
You may qualify if:
- Diagnosis of Acquired Aplastic Anemia
- Relapse/refractory to at least 1 immunosuppressive first line treatment
- Not eligible to allogeneic bone marrow transplantation
You may not qualify if:
- Previous or current malignancy
- Active or latent infectious disease
- Positive serologic tests for HIV, HCV, HBV, HTLV-1 and 2, Syphilis or Chagas disease
- Previous drug reaction for antithymocyte globulin, cyclosporin or corticosteroids
- Severe organic impairment (renal, hepatic, cardiac, pulmonary)
- Uncontrolled hypertension or diabetes
- Pregnancy
- Previous history of allergic reaction to penicillin or streptomycin
- Severe psychiatric disorder
