Study summary

Radial forearm free flap (RFFF) reconstruction is commonly used for head and neck defects but is associated with donor-site morbidity, including neuropathic pain and sensory disturbance. This randomized controlled pilot study evaluates whether placement of a soft tissue matrix over the superficial radial nerve at the donor site reduces neuropathic pain and improves sensory outcomes compared to standard closure alone.

Read the detailed description

Radial forearm free flap (RFFF) harvest is associated with significant donor-site morbidity, including neuropathic pain, hypoesthesia, and functional impairment related to superficial radial nerve irritation and postoperative scar formation. Current donor-site management focuses on wound closure and healing but does not directly address nerve protection.

Avive+ Soft Tissue Matrix is a human-derived biologic material designed for soft tissue reinforcement and protection. Its use as a barrier over surgically manipulated nerves is biologically plausible but has not been studied in this clinical context.

This study is a prospective, randomized controlled pilot trial designed to evaluate the feasibility, safety, and preliminary efficacy of Avive+ placement over the superficial radial nerve during RFFF harvest. Subjects will be randomized to standard closure versus Avive+ placement plus standard closure. Outcomes will focus on neuropathic pain, sensory function, and wound complications.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. Clinically Significant Neuropathic Pain at 6 Months - DN4 score

    A DN4 questionnaire score of 4 or higher out of 10 indicates a high probability of neuropathic pain. This validated tool, which can be viewed in this DN4 Questionnaire consists of seven patient-interview questions and three clinician-examination items, with a total score distinguishing neuropathic from non-neuropathic pain. A score greater than or equal to 4 is considered positive for neuropathic pain

    Time frame: 6 months

  2. Clinically Significant Neuropathic Pain at 6 Months - Numeric Rating Scale

    Numeric Rating Scale (NRS) is used to measure pain, where 0 is "no pain" and 10 is "worst pain imaginable"

    Time frame: 6 months

Secondary outcomes

  1. Average Pain Severity

    Numeric Rating Scale (NRS): Commonly used in healthcare to measure pain, where 0 is "no pain" and 10 is "worst pain imaginable"

    Time frame: 1, 3, 6, and 12 months

  2. Average Sensory Function with Semmes-Weinstein monofilament testing

    The Semmes-Weinstein monofilament test is a quick, non-invasive, and objective clinical exam used to evaluate nerve function by measuring skin sensitivity to light touch and pressure.

    Time frame: 1, 3, 6, and 12 months

  3. Average Sensory Function with Static 2-point discrimination

    Static 2-point discrimination (2PD) is a clinical test measuring the minimum distance at which a patient can perceive two simultaneous touch stimuli as distinct, rather than one, using a device like an aesthesiometer or disk-criminator.

    Time frame: 1, 3, 6, and 12 months

  4. Percentage of Skin Graft Loss

    Measured by percentage of 0-100% total graft loss.

    Time frame: up to 3 months

  5. Number of Participants that develop Infection

    Measured by presence of cellulitis/purulence requiring antibiotics and/or surgical debridement with antibiotics.

    Time frame: Up to 3 months

  6. Number of participants with Tendon Exposure

    Measured by number of participants with visual appearance of tendon exposure.

    Time frame: up to 3 months

  7. Change in QuickDASH score

    The QuickDASH is an 11-item questionnaire assessing upper limb musculoskeletal disability, scoring from 0 (no disability) to 100 (most severe).

    Time frame: 3, 6, and 12 months

Start is estimated for Nov 2026; primary completion for Dec 2029, 37 months later.

Of 437 non-industry interventional studies with no phase under Head and Neck Neoplasms, half reached primary completion within 33 months of starting (the median), counting those still running; a quarter within 18 and three quarters within 71. This study's planned 37 months is above that.

Counting every sponsor, half of 455 studies reached it within 32 months; a quarter within 18 and three quarters within 70.

Start moved once since we started tracking on Sep 25, 2026: Aug 2026 → Nov 2026, on Sep 25, 2026.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
