The overall objective of this study is to determine the safety of PEG fusion when used with primary repair or reconstruction in patients with an acute upper extremity peripheral nerve injury. PEG is safe and effective for extending the half-life of circulating pharmaceutical products, when used in conjunction with a topical hemostatic agent in surgical wounds, and when used as a colon cleanser for endoscopic surgical procedures. However, PEG fusion has not been rigorously tested as a safe reagent to promote nerve regeneration in humans. Therefore, the goal of this Phase 2a clinical trial is to establish safety data and to examine the effect of PEG fusion on clinical outcomes including recovery of sensory and motor function. Results will be externally validated using data collected in the DoD funded prospective NERVE study and will provide preliminary evidence to power a larger phase II efficacy trial.
Ages 18-80
Sustained a complete peripheral nerve injury resulting from upper extremity trauma presenting within 48 hours of injury
Involves injury or dysfunction to motor and/or sensory function of the axillary, radial, median, ulnar, or musculocutaneous nerve with injury localized between the proximal humerus and the distal flexion crease of the wrist
Involves a "mixed" nerve segment (i.e., involves a location of any of the above specified nerves that can be expected to have both sensory and motor axons present).
Patients beginning surgery within hours after injury.
Injury to the brachial plexus nerves
Injury to the nerves distal to the distal flexion crease of the wrist
Injury that involves a distal extension of the parent nerve that is considered sensory only (superficial radial nerve, lateral antebrachial cutaneous nerve, etc.) or the posterior interosseus or anterior interosseus nerve distal to the midpoint of the forearm (i.e., distal to what can be considered the main motor branches of the PIN and AIN).

Drug• PEG fusion is the application of a polyethylene glycol (PEG) using a combination of sequenced reagents to a freshly performed nerve coaptation, or neurorrhaphy, to allow the axonal membranes of the proximal and distal axonal stumps to fuse back together and re-establish full axonal continuity.
Complications or problems that occur with in the first 30 days.
Complications or problems include surgical site infections, wound dehiscence/breakdown, exposure of nerves and/or their repairs and reconstructions, breakdown of nerve repair or reconstruction, seroma/hematoma requiring an additional procedure to treat, and any other local wound complications related to the zone of nerve injury that require an additional surgical procedure
