Scaffold Biomaterial for Neuropathy
What You Need to Know Before You Apply
What is the purpose of this trial?
The trial aims to test the safety of a new nerve repair method for patients requiring a sural nerve biopsy, a procedure that removes a small piece of nerve for testing. After the standard biopsy, patients often experience discomfort such as swelling and tenderness. The trial will compare patients receiving a synthetic nerve tube for nerve repair with those who do not receive any repair. Ideal participants are those already needing a sural nerve biopsy and who do not have conditions like diabetes or recent major heart problems.
As an unphased trial, this study provides patients the opportunity to contribute to innovative research that could enhance nerve repair techniques.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
What prior data suggests that this nerve repair technique is safe?
Research has shown that using a man-made tube to repair nerves is generally safe. In one study, 82% of patients experienced significant recovery after their nerve repairs, with no related side effects reported. Another study used 3D-printed tubes for nerve repair, also without any side effects. These treatments appear promising in helping nerves heal faster after surgery. While these results are encouraging, individual experiences may vary.12345
Why are researchers excited about this trial?
Researchers are excited about the new approach to neuropathy treatment involving a scaffold biomaterial because it directly addresses nerve repair, which is not a focus of current treatments. Unlike standard care options that mainly manage symptoms or slow disease progression, this method employs a synthetic polymer nerve tube (PCLF) to bridge nerve defects. This innovative technique aims to promote actual nerve regeneration, potentially restoring function more effectively. Additionally, by integrating nerve repair with a biopsy, it offers a comprehensive approach that could lead to better outcomes for patients with neuropathy.
What evidence suggests that this trial's treatments could be effective for neuropathy?
Research has shown that synthetic tubes can aid in nerve repair. Studies have found these tubes to be safer and more effective than traditional methods for repairing sensory nerves. One study found that these tubes can accelerate nerve healing after surgery. In this trial, participants in the "Biopsy + Nerve Repair" arm will undergo nerve repair using these synthetic polymer nerve tubes. This suggests that the nerve repair treatment being tested could help reduce swelling and pain after a nerve biopsy. Meanwhile, participants in the "Biopsy Only" arm will undergo the biopsy procedure without nerve repair.26789

Are You a Good Fit for This Trial?
This trial is for adults aged 18-75 with certain nerve conditions who need a sural nerve biopsy and can follow the study plan. They must have a specific level of nerve signal strength, not smoke, and not be pregnant or breastfeeding. People with recent major heart issues, immune disorders (except thyroid conditions), previous trauma at the biopsy site, or infections like MRSA are excluded.Inclusion Criteria
Exclusion Criteria
Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Surgery
Participants undergo the surgical procedure of nerve biopsy with or without nerve repair
Post-Surgery Monitoring
Participants are monitored for post-surgical reactions and safety, including physical/neurological exams and sural nerve ultrasonography
Long-term Follow-up
Participants are monitored for safety and effectiveness, including assessments of neuroma formation and sensory nerve regeneration
What Are the Treatments Tested in This Trial?
Interventions
- Biopsy + Nerve Repair
- Biopsy Only
Trial Overview
The study is testing the safety of a new biomaterial used in repairing nerves after a biopsy compared to no repair. Participants will either receive this novel scaffold biomaterial during their routine surgery or just undergo the biopsy without any nerve repair.
How Is the Trial Designed?
2
Treatment groups
Experimental Treatment
Placebo Group
Subjects will undergo standard sural nerve biopsy plus repair of the 6 cm nerve defect using a synthetic polymer (PCLF) nerve tube.
Subjects will undergo the same standard sural nerve biopsy procedure as the Experimental Group, but will not include the nerve repair.
