The patient previously received local injections, including steroids within the last 30 days 10. Signs of other causes for lateral elbow pain (posterior interosseous nerve entrapment, osteochondral lesion). 11. Wounds around the elbow 12. Likely problems, in the judgment of the investigator, with maintaining follow-up. 13. Clinically significant abnormalities in hematology and blood chemistry lab tests at screening that in the opinion of the investigator might interfere with the patient's safety or participation in the study. 14.
