  Purpose

Osteodysplasia or poorly formed bones, "brittle bones" is a genetic disease with no known proven treatments. Some forms of osteodysplasia may cause severe disability and even death.

Eligible patients were limited to those children with Osteodysplasia who had undergone a previous allogeneic bone marrow transplant at St. Jude. The study intervention involved an infusion of a specified number of ex vivo expanded stromal cells obtained from the bone marrow of the same donor from whom they received their primary transplant procedure. These bone marrow stromal cells can become bone-forming cells, called osteoblasts. Participants then received 2 infusions of ex vivo expanded, gene marked cells not less than 6 months after bone marrow transplantation. The second cell infusion occurred between 14 to 21 days after the first infusion in the absence of toxicity. The goal of the study was to evaluate the safety and toxicity of these infusions.

1 Procedure: Marrow stromal cell infusion

This is a pilot study of infusions of ex vivo expanded, gene marked donor bone marrow stromal cells following allogeneic bone marrow transplantation. The study is a within patient dose escalation safety evaluation. It is believed that this patient population may benefit from these donor stromal cell infusions.

As the stromal cells will be obtained from the original stem cell donor, no conditioning is required.

Patients will receive two infusions of mesenchymal cells (MSC) approximately 14 to 21 days apart unless there is unacceptable toxicity after the first infusion. The first dose of cells to be given will be 1x10^6 MSC/kg and the second dose of cells will be 5x10^6 MSC/kg. The patients will be followed for approximately 28 days following the second infusion for any toxicity. Only after all six patients have safely completed both infusions will we consider 5 x 10^6 MSC/kg a safe dose of allogeneic mesenchymal stem cells for infusion.

Other Names:
  • Marrow stromal cell infusion
  • Gene marking
  • mesenchymal cells

Detailed Description:
  • To determine whether these ex vivo expanded, gene marked marrow stromal cells will engraft in the recipient's bone, bone marrow, and/or skin.
  • To begin to investigate whether high proliferative mesenchymal progenitor cells can be expanded ex vivo and retain their progenitor potential in vivo.
  • To begin to investigate whether ex vivo expanded bone marrow stromal cells can ameliorate the skeletal dysplasias associated with various genetic disorders.
