This study is being undertaken to verify the safety and performance of Adaprev™, a Class III medical device, when administered as a short term implant into the tendon sheath at the time of surgery, on the post-operative function of severed digital tendons. Subjects are randomised to either Adaprev or standard care and attend visits for 26 weeks following surgery. This clinical investigation will recruit 44 subjects in the UK at up to 10 clinical trial sites.

Condition Intervention
Tendon Injuries
Device: Adaprev

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: Double Blind (Subject, Outcomes Assessor)

Official Title: A Randomized, Double Blind Clinical Investigation to Evaluate the Safety, Tolerability, and Preliminary Performance of Adaprev™ in Improving Recovery of Tendon Function in Subjects Undergoing Surgical Repair of Flexor Tendons in Zone II of the Hand

Further study details as provided by Renovo:

Primary Outcome Measures:
  • The primary trial endpoint will be the assessment of safety and local tolerability for a period up to twenty six weeks after dosing. [ Time Frame: 26 weeks post surgery ]

Secondary Outcome Measures:
  • The secondary endpoint will be an evaluation of the performance of Adaprev™ as measured by the range of motion of the treated finger at twenty six weeks after tendon repair [ Time Frame: 26 weeks post surgery ]
