A Study of NTX-001 in the Treatment and Prevention of Facial Paralysis Requiring Surgical Repair.

Inclusion Criteria: The subject has clinical evidence of facial paralysis requiring facial nerve repair from conditions or interventions that have or may result in paralysis. Exclusion Criteria: Subjects whose nerve repair will occur greater than 48 hours after nerve transection. Subjects requiring repair of the intracranial portion of the facial nerve. Subjects requiring repair involving an allograft or conduit except for procedures that require grafting of the other nerve branches when repairing the main facial nerve. Subjects with Bell's palsy that have signs of spontaneous recovery by 12 months. Subjects who, in the judgment of the investigator, are not likely to demonstrate meaningful recovery within 6 weeks due to significant facial muscle atrophy. Subjects on chronic corticosteroid therapy within 14 days of repair. The subject has documented history or clinical signs of: Clinically significant neuropathy from any cause i.e., medications, chemotherapy, diabetes; Clinically significant systemic neuromuscular disease; Clinically significant local or systemic neurological deficit from other than the condition under study such as stroke; Or other treatments are known to affect the growth and/or physiology of the neural and vascular system with the exception of radiation therapy; The subject has a known allergy to polyethylene glycol (PEG) or human-grade silicone. The subject is not able to strictly adhere to the rules of the current clinical protocol, e.g., signif…
