Long-Term Follow-up of the Safety and Efficacy of RCT-01 in Men and Women With Unilateral, Chronic Achilles Tendinosis
- Conditions
- TendinosisTendinopathy
- Registration Number
- NCT02655042
- Lead Sponsor
- RepliCel Life Sciences, Inc.
- Brief Summary
The primary purpose of this study is to assess the long-term safety profile of RCT-01 injections as compared to placebo injections. This study will also measure the long-term impact these injections will have on tendon structure and function and the symptoms of Achilles tendinosis.
This is study is designed to follow participants who have completed participation in a clinical trial where they received injections of either RCT-01 or placebo in the Achilles tendon. No clinical interventions will be performed as part of study procedures.
The day of study entry (Visit 1) will be coordinated with the participant's final visit in the earlier clinical trial. All participants will return to the clinic for repeat assessments of their Achilles tendinosis and overall health 6, 12 and 18 months after study entry. Furthermore, they will complete 'telephone visits'; during which they will report information on their overall health; 3, 9, and 15 months after study entry. Total duration of patient participation is approximately 18 months.

- Primary Outcome Measures
Name Time Method Incidence of adverse events 24 months post-injection Comparison of the safety profile between RCT-01/placebo treatment groups. The safety profile is defined by the incidence, relationship to treatment, severity and seriousness of adverse events.
- Secondary Outcome Measures
Name Time Method Tendon condition (appearance) 24 months post-injection Ultrasound imaging will be utilized to measure region and relative location (from calcaneus) of damage and overall tendon size (in mm)
Tendon condition (fibrillar pattern) 24 months post-injection Fibrillar pattern observed during ultrasound imaging of tendon structure will be graded on ordinal scale.
Victorian Institute of Sport Assessment - Achilles (VISA-A) questionnaire 24 months post-injection pain on palpation and pain on loading (running/jumping)
Modified Tegner Activity Scale 24 months post-injection Tendon condition (blood flow) 24 months post-injection Ultrasound imaging will be utilized to measure blood flow (vascularization) within the tendon. Defined on ordinal scale
SF-36 questionnaire 24 months post-injection quality of life questionnaire
Tendon condition (presence of abnormalities) 24 months post-injection Presence/absence of intratentinous calcification, observable tears, and irregularities in calcaneus bone structure will be noted during ultrasound imaging.
