NCT00632034

Brief Summary

The aim of this trial is to determine the safety and tolerability of expanded autologous progeny of an adult CD34+ (haemopoietic) stem cell subset when infused directly into the tibial artery of patients with recent tibial fracture. The trial will also seek to determine clinical improvement or deterioration by measurement of clinical parameters such as, length of time to union of the fracture, changes in bone mineral density, improvements in pain scores (VAS), functional ability (TUGT) and IPAQ scores.

Outcome Measures

Primary Outcomes (1)

  • To assess the safety of expanded autologous progeny of an adult CD34+ stem cell subset when introduced into the tibial artery and to determine absence of adverse events at the maximum dose of cells of 1,000,000,000 cells in a dose escalation regime.

    1 year

Secondary Outcomes (1)

  • To assess improvement in bony union as measured by imaging modalities and determine whether there are any significant improvements in early restoration of function as reported by the patients.

    1 year

Study Arms (1)

EXPERIMENTAL
Other: CD34+ haemopoietic stem cells

Interventions

Expanded subset of CD34+ haemopoietic stem cell. Harvested from pelvic marrow aspiration at Day 0 of study. Undergoes refinement and minimum of 1000 fold expansion over 7 days in a dose escalation regime of a maximum dose of 1,000,000,000 cells in 5 millilitres. Injected at Day 7 via contralateral femoral artery under angiographic guidance. First regime up to 10,000,000 cells, second 100,000,000 cells, final regime maximum of 1,000,000,000 cells.
