MOBILE Trial design: Patients with critical limb ischemia were randomized to intramuscular injection of bone marrow-derived stem cells (n = 119) vs. placebo injection (n = 36). (p = 0.33) Results Serious adverse events: 59% of the stem cell group vs. 69% of the placebo group (p = 0.33) Death or amputation: 20% of the stem cell group vs. 31% of the placebo group (p = 0.22) 69 59 % Conclusions Among patients with critical limb ischemia, intramuscular injection of bone marrow-derived stem cells was feasible This small pilot study demonstrated the safety of stem cell injection Stem cell Placebo Presented by Dr. Michael P.
