This study is a comparison of sensory recovery outcomes from the use of AVANCE and hollow tube conduits for peripheral nerve gap repairs in the hand.

Condition Intervention Phase
Traumatic Nerve Injury Device: Hollow tube nerve conduit, synthetic or biosynthetic Other: Processed Human Nerve Tissue Scaffold Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Multicenter, Prospective, Randomized, Comparative Study of Hollow Nerve Conduit and Avance Nerve Graft Evaluating Recovery Outcomes of Nerve Repair in the Hand. (CHANGE)

Further study details as provided by AxoGen, Inc:

Primary Outcome Measures:
  • Recovery of Static Two-point Discrimination in Target Digit [ Time Frame: 1, 3, 6, 9 and 12 Months ]

Secondary Outcome Measures:

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Require primary or secondary nerve injury repair with Hollow Nerve Conduit or AVANCE™ in at least 1 digital nerve;
  • Undergo End to End nerve to nerve graft coaptation on both the proximal and distal portion of the nerve gap in the AVANCE™ group or nerve entubulation in the Hollow Nerve Conduit group;
  • Be willing to comply with all aspects of the treatment and evaluation schedule over a 12 Month duration; and
  • Sign and date an IRB-approved written informed consent prior to initiation of any study procedures, including screening procedures.

Exclusion Criteria:

  • Nerve gaps of < 5 mm or > 20 mm;
  • Estimated distance of regeneration of >125 mm (distance from injury site to sensory target)
  • Nerve crush or avulsion injuries;
  • Incomplete nerve transections;
  • Injury requiring replantation of target digit;
  • Contralateral digital injuries corresponding to the target digit;
  • Nerve injuries in the affected limb proximal to the crease of the wrist;
  • End to side nerve repair;
  • Injuries with significant vascular damage which may impair adequate perfusion of the target limb;
  • Subjects who are undergoing treatment with chemotherapy, radiation therapy, or other know treatment which affects the growth of neural and/or vascular system;
  • Use of bovine collagen based hollow nerve conduit in a subject with known or suspected bovine sensitivity;
  • Subjects age ≤18 years or ≥70 years;
  • History neuropathy, diabetic or any other known neuropathy;
  • Secondary nerve repair >12 weeks post initial injury;
  • Currently enrolled in another investigational study;
  • Expected use of medications during the study that are known to cause peripheral neuropathy;
  • History or Reynaud's or other disorder known to compromise circulation or sensation in the upper extremity; and
  • Any subject who at the discretion of the Investigator is not suitable for inclusion in the study.
