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.

Further study details as provided by Imperial College London:

Primary Outcome Measures:
  • 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 x 109 cells in 5.0mL. [ Time Frame: 1 year ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • 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. [ Time Frame: 1 year ] [ Designated as safety issue: No ]

Estimated Enrollment: 32
Study Start Date: April 2008
Estimated Study Completion Date: April 2011
Estimated Primary Completion Date: April 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1 Other: CD34+ haemopoietic stem cells
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 up to maximum dose of 1000,000,000 cells in 5 millilitres. Injected at Day 7 via contralateral femoral artery under angiographic guidance.
