Porcine Extracellular Matrix Nerve Wrap in Neck Dissection for Head and Neck Cancer

An interventional study of Porcine Extracellular Matrix Nerve Wrap (AxoGuard Nerve Protector™) in Head and Neck Cancer, Neck Dissection and Postoperative Complications, sponsored by Henry Ford Health System. Suspended at 1 site in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2025-12-05.

Why this study was suspended
Dr Tam have collected the first 20 patients for interim analysis per the protocol, and are trying to get these data to perform interim analyses on these data to best understand how to move forwards.

Study summary

Perform a preliminary efficacy study using the porcine extracellular matrix nerve wrap (AxoGuard Nerve Protector™, AxoGen Inc., Alachua, FL) to wrap the spinal accessory nerve (SAN) during neck dissections for head and neck cancer as it relates to postoperative shoulder function, both subjectively and objectively.

Read the detailed description

Many patients who have surgery for head and neck cancer also need a procedure called a neck dissection, where lymph nodes and tissue are removed from the neck. During this surgery, even when a nerve called the spinal accessory nerve (SAN) is carefully preserved, patients often have shoulder problems afterward. These problems can include pain, weakness, and difficulty lifting the arm, which can affect daily activities and quality of life.

This study is testing whether using a special nerve wrap made from pig tissue (called AxoGuard® Nerve Protector) can help protect the spinal accessory nerve during surgery and improve shoulder movement and strength after surgery. This nerve wrap is already used in other types of nerve surgeries and may help the nerve heal better by reducing scar tissue and irritation.

Study arms

  • Experimental
    Treatment Arm - Neck dissection with AxoGuard Nerve Protector™

    Participants undergo neck dissection surgery for head and neck cancer, during which the spinal accessory nerve (SAN) is wrapped with the AxoGuard Nerve Protector™ (porcine extracellular matrix nerve wrap). This intervention aims to improve postoperative shoulder function by protecting and supporting the nerve during healing. Postoperative physical therapy evaluations will be conducted at baseline, immediate post-op, 1, 6, and 12 months.

    Device: Porcine Extracellular Matrix Nerve Wrap (AxoGuard Nerve Protector™)

  • No intervention
    Control Arm - Neck dissection without AxoGuard Nerve Protector™.

    Participants undergo standard neck dissection surgery for head and neck cancer without the application of the AxoGuard Nerve Protector™. Postoperative physical therapy evaluations will be conducted at baseline, immediate post-op, 1, 6, and 12 months to assess shoulder function.

Interventions

  • DevicePorcine Extracellular Matrix Nerve Wrap (AxoGuard Nerve Protector™)

    The intervention involves the application of the AxoGuard Nerve Protector™, a nerve wrap derived from porcine extracellular matrix (ECM), to the spinal accessory nerve (SAN) during neck dissection surgery in head and neck cancer patients. The device is designed to protect and support the nerve by preserving the extracellular matrix and creating a favorable environment for nerve healing. This helps prevent inflammation and fibrosis around the nerve, potentially improving postoperative shoulder function. The nerve wrap is applied intraoperatively after dissection but before surgical closure. The study compares this intervention to standard neck dissection without nerve wrapping.

What researchers measure

Primary outcomes

  1. Change from baseline in shoulder flexion active range of motion (degrees)

    Shoulder flexion active range of motion will be measured using goniometry. A clinically significant decline is defined as a ≥12° decrease compared to preoperative baseline. Unit of Measure: Degrees

    Time frame: From preoperative baseline assessment up to 12 months post-surgery

  2. Change from baseline in Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) score

    Subjective upper extremity function will be assessed using the QuickDASH questionnaire (0-100 scale, higher scores indicate worse disability). Unit of Measure: Score

    Time frame: From preoperative baseline assessment up to 12 months post-surgery

  3. Change from baseline in Neck Dissection Impairment Index (NDII) score

    Subjective shoulder-related quality of life will be assessed using the NDII questionnaire (0-50 scale, higher scores indicate greater impairment). Unit of Measure: Score

    Time frame: From preoperative baseline assessment up to 12 months post-surgery

  4. Change from baseline in shoulder abduction active range of motion (degrees

    Shoulder abduction active range of motion will be measured using goniometry. A clinically significant decline is defined as a ≥23° decrease compared to preoperative baseline. Unit of Measure: Degrees

    Time frame: From preoperative baseline assessment up to 12 months post-surgery
