2 de octubre de 2026 actualizado por: Neuraptive Therapeutics Inc.

Un estudio de fase 3, multicéntrico, aleatorizado, ciego para el sujeto y el evaluador, que evalúa la seguridad y eficacia de NTX-001 en comparación con el estándar de atención (neurorrafia) en el tratamiento de nervios seccionados de las extremidades superiores que requieren reparación quirúrgica.

NTX-001 is a single use surgical product intended for use in conjunction with standard suture neurorrhaphy of severed nerves in patients between 18 and 80.

Descripción detallada

NTX-001 has been developed as a surgical product to be used in conjunction with standard suture neurorrhaphy of a severed nerve. Use of NTX-001 is intended to safely accelerate the often slow and diminished return of function in repaired nerves. It often takes months and/or years to determine if function will be restored. By that point, restoration is often incomplete and can result in lifelong motor and/or sensory deficits. By reconnecting (PEG-fusion) a substantial number of axons within a severed nerve, the degeneration-regeneration cycle and subsequent atrophy may be reduced or even prevented for those axons and their targets, respectively. NTX-001 (PEG-fusion) has the potential to avoid the consequences of protracted denervation of distal target tissues by eliminating the period of total denervation thus reducing the time to stable recovery and providing greater innervation to affected tissues.

Mean Michigan Hand Questionnaire (MHQ) Two Domain Score (ADL and Pain)
Periodo de tiempo: 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.
Screening Visit, Week 24
Safety - Columbia-Suicide Severity Rating Scale
Periodo de tiempo: Screening 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.

The MHQ quantifies different impairments between the subjects in uninjured and involved upper extremities. A general survey of hand function includes twenty-five items for the right and the left hand, as well as questions for both hands. Questions regarding function specifically refer to the impact of the involved hand and/or wrist on the activity which presumably takes all joints of the upper extremity into account. The overall questionnaire is scored from 0 to 100, with 100 being the optimal score.

Medical Research Council Classification (MRCC) Motor Score
Periodo de tiempo: Weeks 2, 4, 8, 12, 24, 36, 48

This assessment is conducted on mixed motor nerve injuries only. Strength can best be assessed by isolating an individual muscle group and comparing power with that of the subject. It can be conducted to assess larger muscles or muscle groups as well as intrinsic muscles of the hand. Measuring the difference between the affected limb and the contralateral limb. 0/5 is no muscle activation whatsoever; 1/5 is muscle activation without limb movement; 2/5 implies that the limb can be moved only when gravity is taken out of the equation; 3/5 means that the subject can overcome gravity but not resistance;• 4/5 (or 4+ or 4-) implies weakness with enough strength to overcome varying degrees of physical resistance; 5/5 is full strength.
