  • RFA for Stem cell tx for cv disease
  • LV dysfunction patients undergoing device tx
  • Network of 5 clinical centers (VU applying for one), one DCC
  • Demo experience in multi-center trials
  • Commit to disseminate results
  • Phase I/II studies
  • Sample size calculations
  • Will choose 2 protocols
  • $300K/yr including co-Is at >= 10% FTE
  • Development core for young clinical investigators
  • 2 page proposal by 27Jan06 describing 2 protocols with sample sizes
  • Main proposal 10Mar06 if first one accepted


  • Cell delivery
  • ID cell types for tx
  • Track cells, standardize cell/tx procedures
  • Evaluate patient groups
  • Define endpoints
  • Knowledge base for tx decisions
  • Dissemination and training

Possible Endpoints


  • Exercise capacity
  • Hemodynamics
  • Health/function survey
  • HRV (non-specific but sensitive)

Ventricular Structure/Function

  • MRI (gold standard but can't use in ICD or pacemaker patients)
  • 3d Echo (tissue Doppler)
  • RVG (MUGA), (LVEF, regional EF, LV volume)
  • Contractile reserve (LVSWI, stress LV function)

Cell Survival

  • Biomarkers
  • PET scan (metabolism)
  • MRI




  • EKG
  • Holter/event monitorhtt
  • Signal-averaged EKG

Experimental Designs

Protocol 1

  • 2 * 2 * 2 factorial design

Protocol 2

P with GCSF BM Control
IM Per Im Per  

Sample Size Calculation

Based on precision or power

Information needed from the clinician
  • Pick primary/most important outcome
  • Standard errors of each group from the primary/pilot/animal study
