Study Description
Brief Summary:
The purpose of this study is to determine if the method of intrabone infusion of hematologic stem cells can increase and accelerate hematopoietic reconstitution after umbilical cord blood transplantation in pediatric patients.

Condition or disease Intervention/treatment Phase
Hematopoietic Stem Cell Transplantation Procedure: Intrabone infusion of umbilical cord blood stem cells Phase 2

Detailed Description:

Umbilical cord blood transplantation (UCBT) has been increasingly used to treat malignant and non-malignant haematological, immunodeficiency and some metabolic diseases. UCBT offers the advantages of easy procurement, no risk to donors, a reduced risk of transmitting infections, immediate availability of cryopreserved units, and acceptable partial HLA mismatches. However, patients treated with UCBT show delayed hematopoietic and immunological recoveries, have higher rates of infection, and relapse from the original malignant disease, which can all lead to life threatening problems. UCBT can also result in a higher rate of graft failure compared to other hematopoietic stem cell transplantation (HSCT) sources. The problem of a slower hematopoietic recovery post-UCBT has been addressed using a number of different approaches in adult patients.In adults, use of intrabone injection of cord blood results in a faster hematopoietic recovery in a phase II study. However, there is no clinical trial in pediatric patients.

This study is addressed to determine if a change in the cord blood stem cell infusion method can increase and accelerate hematopoietic reconstitution after UCBT in pediatric patients.

Procedure: Intrabone infusion of umbilical cord blood stem cells

Outcome Measures

Primary Outcome Measures :
  1. Platelet recovery rate [ Time Frame: at 100 days post- transplantation ]
    First of seven days of untransfused platelet count higher than 20 x 10^9/L

Secondary Outcome Measures :
  1. Neutrophil recovery rate [ Time Frame: at 60 days post- transplantation ]
    First of three days of absolute neutrophil count equal or higher than 0.5 x 10^9/L

  2. Immunological reconstitution [ Time Frame: at 30, 60, 100, 180, and 360 days post- transplantation ]
    Total number of T cells (and subpopulations), B and NK (natural killer) cells in peripheral blood at different time-points

  3. Donor chimerism rate [ Time Frame: at 30, 60,100, and 180 days post-transplantation ]
    Percentage of donor(s) cells in peripheral blood at different time-points

  4. Acute GVHD (grade 2-4) rate [ Time Frame: at 180 days ]
    Incidence of grade II-IV acute GVHD (Graft versus Host Disease)

  5. Infection rate (bacterial, viral, fungal and parasitic) [ Time Frame: at 180 days post-transplantation ]
    Clinical and microbiological documented infections will be reported according to anatomic site, date of onset and microorganism

  6. Event-free and overall survival [ Time Frame: at 2 years ]
    Event-free survival is defined as the time interval between transplantation and relapse, graft rejection, death or last follow-up, whichever occurs first; Overall survival is defined as the time between transplantation and death or last follow-up

  7. Adverse infections (grade and frequency) [ Time Frame: at one month post-transplantation ]
    Toxicity will be assessed using the Common Terminology Criteria for Adverse Events v4.0

  8. chronic GVHD [ Time Frame: at 2 years post-transplantation ]
    Incidence of chronic GVHD (Graft versus Host Disease) will be scored according to NIH consensus on chronic GVHD
