Summary

Background:

Severe aplastic anemia (SAA) and myelodysplastic syndrome (MDS) are bone marrow diseases. People with these diseases usually need a bone marrow transplant. Researchers are testing ways to make stem cell transplant safer and more effective.

Objective:

To test if treating people with SAA or MDS with a co-infusion of blood stem cells from a family member and cord blood stem cells from an unrelated donor is safe and effective.

Eligibility:

Recipients ages 4-60 with SAA or MDS

Donors ages 4-75

Design:

Recipients will be screened with:

* Blood, lung, and heart tests
* Bone marrow biopsy
* CT scan

Recipients will have an IV line placed into a vein in the neck. Starting 11 days before the transplant they will have several chemotherapy infusions and 1 30-minute radiation dose.

Recipients will get the donor cells through the IV line. They will stay in the hospital 3-4 weeks. After discharge, they will have visits:

* First 3-4 months: 1-2 times weekly
* Then every 6 months for 5 years

Donors will be screened with:

* Physical exam
* Medical history
* Blood tests

Donors veins will be checked for suitability for stem cell collection. They may need an IV line to be placed in a thigh vein.

Donors will get Filgrastim or biosimilar (G-CSF) injections daily for 5-7 days. On the last day, they will have apheresis: Blood drawn from one arm or leg runs through a machine and into the other arm or leg. This may be repeated 2 days or 2-4 weeks later.

Conditions

  • Severe Aplastic Anemia
  • Hypo-Plastic MDS
  • Myelodysplastic Syndrome (MDS)

Interventions

BIOLOGICAL

Omidubicel (former CordIn)

Stem/progenitor cell-based product of purified CD133+ cells composed of ex vivo expanded allogeneic umbilical/unrelated cord blood (UCB) cells. CordIn(TM) comprises: 1) cord blood-derived ex vivo expanded CD133+ cells (CordIn (TM) cultured fraction (CF)); and 2) the non-cultured cell fraction (CD133-) of the same CBU (CordIn(TM) Non-cultured Fraction (NF)). Both fractions, i.e. CordIn(TM) CF and CordIn(TM) NF are kept frozen until they are infused on the day of transplantation.

DEVICE

Miltenyi CliniMACS(R) CD34 Reagent System

The CliniMACS CD34 Reagent System is a medical device system that is designed for the in vitro enrichment of CD34+ target cells from heterogeneous hematologic cell populations. The process of CD34+ cell selection results in simultaneous passive depletion of donor lymphocytes, potentially obviating the need for immunosuppressive drugs to prevent GVHD.
