NTX-001 for Upper Extremity Nerve Lacerations

This study is evaluating NTX-001, a surgical product designed to help repair severed nerves in the arm or hand. NTX-001 is applied during surgery along with standard nerve repair techniques. It aims to speed up nerve recovery and improve function by reconnecting nerve fibers. You may be able to join if you are between 18 and 80 years old and have a severe nerve injury in your arm or hand. Researchers will measure success by looking at how your hand function and pain change over 24 weeks using a questionnaire. The study is planning to enroll 98 people, but its current status is unclear.

Study design
This interventional study plans to enroll 98 participants. The specific phase of the study is not mentioned.
What's involved
You would have a screening visit, and then follow-up visits at weeks 4, 12, 24, and 48. During these visits, your hand function and pain levels will be assessed.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for safety assessments up to 48 weeks after the intervention.

Eligibility criteria

Inclusion

The subject has voluntarily agreed to participate in this study and has signed an Institutional Review Board (IRB) approved informed consent form.
The subject is between eighteen (18) and eighty (80) years of age.
The subject has clinical evidence of a Sunderland's 4th degree (Class II) or 5th degree (Class III) nerve transection(s) that has resulted in upper extremity nerve impairment that requires surgical treatment.

Exclusion

Subjects whose nerve repair will occur greater than 48 hours after nerve transection.
Subjects requiring nerve repair involving an autograft, allograft or conduit(s).
Subjects with multiple transected nerve injuries are allowed into the study only if all injuries are amenable to direct repair.
Subjects who, in the judgement of the investigator, are not likely to demonstrate meaningful recovery within a reasonable time frame during follow up due to significant muscle atrophy or other morbidity.
The subject's injury is a result of a suicide attempt or self- harm.
The subject has documented history or clinical signs of any condition where NTX-001 might not prove beneficial (e.g., systemic neuromuscular disease, systemic neurological deficit, or other treatments known to affect the growth and/or physiology of the neural and vascular system).
The subject has a known allergy to polyethylene glycol (PEG) or human grade silicone.
The subject is pregnant or breastfeeding.
The subject is currently enrolled in another investigational study or has participated in an investigational study within 30 days prior to screening.
  • Mean Michigan Hand Questionnaire (MHQ) Two Domain Score (ADL and Pain)Screening Visit, Week 24

    The subject will complete the MHQ questionnaire at Weeks 2, 4, 6, 8, 10, 12, 16, 20, 24, 30, 36, 42, and 48. A measure of the mean of MHQ in the Two Domains, Activities of Daily Living and Pain Scores, at Week 24 in the NTX-001 group as compared to Standard of Care (SoC). In the ADL subdomain, a higher component score indicates better function. In the Pain subdomain, a higher component score indicates greater pain. A total MHQ score of 100 is considered the best functional score.

  • Safety - Columbia-Suicide Severity Rating ScaleScreening Visit, Weeks 4, 12, and 48

    The Columbia-Suicide Severity Rating Scale (C-SSRS) is a suicide risk assessment tool. The C-SSRS tool asks; whether and when the subject has had a thought about suicide (ideation); what actions they might have taken and what they did to prepare for suicide; whether and when they attempted suicide or began a suicide attempt that was either interrupted by another person or stopped of their own volition. The answers identify whether someone is at risk for suicide, assessing the severity and immediacy of that risk, and gauging the level of support that the person needs. The first assessment is done by study staff at screening. Subsequent assessments will be completed by the subject at Weeks 4, 12, and 48. A score of 0 indicates no risk, 1-2 indicates low risk, and 3+ indicates moderate to high risk.
