This study tests a product called **NTX-001**, which helps fix nerves in the arm that have been cut. When nerves are cut, doctors sew them back together, but it can take a long time for them to work properly again. NTX-001 is a special surgical product used with these stitches to help nerves heal faster and better. The product works by reconnecting more *axons*, or nerve fibers, which are the parts that carry signals in the body. This could mean less waiting time for nerves to start working again and better results in movement and feeling.

Key Points:

• Participants must be between 18-80 years old and have a specific type of nerve injury.
• Study excludes people with certain health conditions, allergies to specific materials, or those pregnant or breastfeeding.
• Nerve repair must occur within 48 hours of injury and no other nerve repair studies can be joined during this time.
