the Safety and Efficacy of Collagen Injection in Patients With Plantar Fasciitis

Phase 4

• Conditions: Plantar Fasciitis
• Interventions: Drug: normal saline; Device: Regenseal

• Registration Number: NCT02539082
• Lead Sponsor: Sewon Cellontech Co., Ltd.

Brief Summary

The primary objective of this study is to evaluate the safety and efficacy of collagen injection in patients with plantar fasciitis

Detailed Description

This study is an open-trial study. Sixty subjects will be participated in it. The study will be explained to the subjects and they voluntarily agreed to participate in it. Their eligibility to participate in the study will be checked, and the patient will receive collagen or a placebo (normal saline) in the plantar facia through randomization. They will be asked to follow the guidelines of the investigators during the study and to visit the hospital seven times, including for screening and the date of re-injection. . At each visit, the subjects undergo a VAS, a clinical laboratory tests, and a physical exam to evaluate the safety and efficacy of Regenseal. (\*Re-injection could be maximum 2times at visit2 and 3, one week apart based on the investigator's judgment after the initial injection. If the subject gets injection on the screening date, the total number of his or her visits will be six.)

Group	Intervention	Description
placebo injection	normal saline	placebo, normal saline, injection in the plantar facia through randomization
Regenseal injection	Regenseal	Regenseal, collagen, injection in the plantar facia through randomization

Primary Outcome Measures

Name	Time	Method
The difference in the 100mmVAS score	3 months after the surgery	The difference in the 100mmVAS between study group and control group at 3 months after the surgery will be compared and analyzed

Secondary Outcome Measures

Name	Time	Method
The difference in the 100mmVAS score	baseline and 6, 12 months after the surgery	The difference in the 100mmVAS between study group and control group at baseline and 6, 12 months after the surgery will be compared and analyzed.
change of Satisfaction evaluation by patients	baseline and 3, 6, 12 months after the surgery	The improvements on the affected ankle at 3 months after injection and six, 12 months after injection of the study and control group will be compared and analyzed. (Patient evaluates the degree of improvement in 5 levels, such as 'excellent, good, satisfactory, no change, and worsened.)
change score of Degree of recovery	baseline and 3, 6, 12 months after the surgery	The score of degree of recovery at baseline will be recorded. The difference between study group and control group in the score of degree of recovery at three, six, and 12months after injection will be compared and analyzed.
change of the thickness in the sonographic evaluation and fluid collection	baseline and 3, 6, 12 months after the surgery	The difference between study group and control group of the thickness in the sonographic evaluation and fluid collection at baseline will be compared with that three months after the surgery. The thickness in the sonographic evaluation and fluid collection six and 12 months will be additionally taken for comparison and analysis.
change of Satisfaction evaluation by physician in charge	baseline and 3, 6, 12 months after the surgery	The improvements on the affected ankle by physician in charge at 3 months after injection and six, 12months after injection of the study and control group will be compared and analyzed. (Physician in charge evaluates the degree of improvement in 5 levels, such as 'excellent, good, satisfactory, no change, and worsened.)
