Clinical Trial Summary

The purpose of this clinical trial is to investigate the utility of composite wrapping comprising human amniotic membrane and allogeneic adipose-derived mesenchymal stem cells (HAM-AdMSC) for augmentation of nerve transfer procedure in upper TBPI patients

Description:

Nerve transfer procedure is recognized as the current gold standard for treating traumatic brachial plexus injury (TBPI). However, despite the current major progress in diagnosis and microsurgical repair, the prognosis in TBPI remains unfavorable due to limited donor nerve and compromised regenerative capability of the nervous system arising from prolonged denervation. Therefore, there is a major need to devise new treatment strategies; and one possible approach is to develop cellular therapies to bioengineer new nerve tissue and/or modulate the endogenous regenerative mechanisms within the injured nerve.

Our previous studies have shown that the peripheral nerve tissue engineering approach using human amniotic membrane seeded with allogeneic adipose-derived MSCs to augment axonal regeneration in nerve transfer of TBPI patient revealed promising functional recovery of the shoulder range of motion (ROM). The investigators plan a non-randomized clinical trial in a single center to investigate the use of a hybrid (composite) between human amniotic membrane (HAM) and allogeneic adipose-derived mesenchymal stem cells (AdMSC) as wrapping in the nerve transfer procedure of upper TBPI patients, with a focus on the augmentation of axonal regeneration

Intervention

Procedure:
• Nerve transfer procedure
Identification of potential donor nerves: phrenic nerve, accessory nerve, intercostal nerve, motor branch nerve innervating long head of triceps muscle, motor branch of ulnar nerve innervating flexor carpi ulnaris (FCU) muscle, and motor branch of median nerve innervating flexor carpi radialis (FCR) muscle. Donor nerve is checked for its viability with an electric stimulator during surgery Viable donor nerve is dissected, transferred to the recipient area, and sutured with end-to-end anastomosis.
• Nerve transfer with HAM-AdMSC composite wrapping
When the nerve transfer procedure is finished, the end-to-end anastomosis is wrapped by a composite consisted of human amniotic membrane and allogeneic adipose-derived mesenchymal stem cells (HAM-AdMSC)

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Active range of motion (AROM) pre-surgery	Shoulder: flexion, extension, abduction, adduction, external rotation, internal rotation. Elbow: flexion and extension. Forearm: pronation and supination. The tests are performed by two blinded assessor, and expressed in degrees.	Pre-surgery
Primary	Active range of motion (AROM) at 12 months follow-up	Shoulder: flexion, extension, abduction, adduction, external rotation, internal rotation. Elbow: flexion and extension. Forearm: pronation and supination. The tests are performed by two blinded assessor, and expressed in degrees.	12 months
Primary	Functional motor power outcome pre-surgery	Measured by Medical Research Council (MRC) scale. The MRC scale consists of 6 values of motor power evaluation, ranging from 0 to 5 (0=No contraction, 1=Flicker or trace contraction, 2=Active movement but eliminated with gravity, 3=Active movement against gravity, 4=Active movement against gravity and resistance, 5=Normal power). The tests are performed by two blinded assessor. A higher score indicates better functional motor power outcome.	Pre-surgery

The tests are performed by two blinded assessor. A higher score indicates better functional motor power outcome.	12 months
Secondary	Initial elbow flexion MRC grade 1 (in months)	Measurement of the length of time (in months) for the patients to show initial contraction (achieve MRC grade 1) of elbow flexion. Previous study by Estrella (2011) showed that the average time for brachial plexus injury patients to achieve an elbow flexion grade M3 after nerve transfer procedure was 7.6 months (range, 5-12 months). As the elbow flexion is the most important movement to restore in treating BPI, the investigators aim to compare the length of time (in months) for the patients to achieve initial contraction (MRC grade 1). The sooner the patients achieve initial elbow flexion MRC grade 1, the better the outcome is.	throughout the study duration (12 months), recorded as the first time reported by the patients
Secondary	Initial elbow flexion MRC grade 3 (in months)	Measurement of the length of time (in months) for the patients to achieve MRC grade 3 (active movement against gravity) of elbow flexion. Previous study by Estrella (2011) showed that the average time for brachial plexus injury patients to achieve an elbow flexion grade M3 after nerve transfer procedure was 7.6 months (range, 5-12 months). As the elbow flexion is the most important movement to restore in treating BPI, the investigators aim to compare the length of time (in months) for the patients to achieve MRC grade 3. The sooner the patients achieve initial elbow flexion MRC grade 3, the better the outcome is.	throughout the study duration (12 months), recorded as the first time reported by the patients
Secondary	Pain outcome pre-surgery	Measured by visual analogue scales (VAS). Patients are asked to described their level of pain from the scale 0 to 10 (0 indicating no pain, 1-3 indicating mild pain, 4-6 indicating moderate pain, 7-9 indicating severe pain, and 10 indicating worst, unbearable pain). The lower scores mean a better pain outcome.	Pre-surgery
Secondary	Pain outcome at 12 months follow-up	Measured by visual analogue scales (VAS). Patients are asked to described their level of pain from the scale 0 to 10 (0 indicating no pain, 1-3 indicating mild pain, 4-6 indicating moderate pain, 7-9 indicating severe pain, and 10 indicating the worst, unbearable pain). The lower scores mean a better pain outcome.	12 months
Secondary	Disabilities of the Arm, Shoulder, and Hand (DASH) score pre-surgery	DASH score is a self-assessment of symptoms and function of the entire upper extremity comprising 30 items. Each item consists of five levels of answers (1=no difficulty/symptoms, 2=mild difficulty/symptoms, 3=moderate difficulty/symptoms, 4=severe difficulty/symptoms, and 5=extreme difficulty (unable to do)/symptoms). The scores are then used to calculate a scale score ranging from 0 (no disability) to 100 (most severe disability). Greater DASH scores reflect greater disability (worse outcome).	pre-surgery
