Brief Summary:
The aim of this study is to evaluate the efficacy and safety of intra-tendon injection of allogeneic adipose-derived mesenchymal stem cells (Allo-ASC) in intractable common extensor tendinosis patients in comparison with a control treatment.

Condition or disease Intervention/treatment Phase
Lateral Epicondylitis Biological: High concentration of Allo-ASC Biological: Low concentration of Allo-ASC Drug: Fibrin glue Drug: Normal saline Phase 2

Detailed Description:

A phase II randomized placebo controlled trial will be done with following 3 groups. Each group will have 10 participants, so, the total patients will be 30 people.

  1. High concentration of Allo-ASC group: stem cell 0.5cc (Total: 10 million cells) + Fibrin glue 0.5cc
  2. Low concentration of Allo-ASC group: stem cell 0.5cc (Total: 1 million cells) + Fibrin glue 0.5cc
  3. Placebo Comparator (Fibrin) group: Normal saline 0.5cc + Fibrin glue 0.5cc The investigators will compare the efficacy difference with visual analogue scale (VAS) during activity (primary outcome), VAS at rest, Mayo elbow performance index (MEPI), grip strength, ultrasonographic assessment at baseline, 6 weeks, 12 weeks, 6 months, 12 months and 24 months after injection. Shear wave elastography (SWE) and magnetic resonance image (MRI) will be done at baseline, 12 weeks, 12 months and 24 months after injection

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Change of pain visual analogue scale (VAS) during activity [ Time Frame: baseline and 12 weeks ]
    Self reported pain intensity during activity will be evaluated by visual analogue scale (0 = no pain, 10 = pain as bad as can be).


Secondary Outcome Measures :
  1. Change of pain visual analogue scale (VAS) during activity [ Time Frame: baseline, 6 weeks, 12 weeks, 6 months, 12 months and 24 months ]
    Self reported pain intensity during activity will be evaluated by visual analogue scale (0 = no pain, 10 = pain as bad as can be).

  2. Change of pain visual analogue scale (VAS) at rest [ Time Frame: baseline, 6 weeks, 12 weeks, 6 months, 12 months and 24 months ]
    Self reported pain intensity at rest will be evaluated by visual analogue scale (0 = no pain, 10 = pain as bad as can be).

  3. Change of Mayo elbow performance index (MEPI) [ Time Frame: baseline, 6 weeks, 12 weeks, 6 months, 12 months and 24 months ]
    The MEPI measures pain, motion, stability, and daily functions. (0 = worst, 100 = best)

  4. Ultrasonographic assessment [ Time Frame: baseline, 6 weeks, 12 weeks, 6 months, 12 months and 24 months ]
    Ultrasonographic findings will be analyzed using a 5-point Likert scale (1: more aggravated, 2: aggravated, 3: same, 4: improved, 5: more improved). Sonographic images will be compared with baseline images by experienced ultrasound examiners being blind to the treatment group and the time points of image achievement.

  5. Shear wave elastography [ Time Frame: baseline, 12 weeks and 24 months ]
    Young modulus and shear wave speed will be obtained

  6. Magnetic resonance image (MRI) assessment [ Time Frame: baseline, 12 weeks and 24 months ]
    MRI findings will be analyzed using a 5-point Likert scale (1: more aggravated, 2: aggravated, 3: same, 4: improved, 5: more improved). MR images will be compared with baseline images by experienced ultrasound examiners being blind to the treatment group and the time points of image achievement.
