Official title: A Phase II, Double-Blind, Randomized, Placebo-Controlled Non-Inferiority Trial of EpiCept™ NP-1 Topical Cream (2% Ketamine / 4% Amitriptyline) vs. Oral Gabapentin in Postherpetic Neuralgia (PHN)
Study design: Treatment, Randomized, Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Active Control, Parallel Assignment, Safety/Efficacy Study
Primary outcome: Improvement in pain intensity
This is a phase II, multicenter, double-blind, randomized, placebo-controlled, parallel group
study of NP-1 and oral gabapentin in approximately 500 patients with PHN. Adult patients with
pain resulting from PHN and meeting all other eligibility requirements will be screened for 7
days to determine their average daily pain intensity. Qualifying patients will be randomized
on a 2: 2:1 basis to NP-1, oral gabapentin, or placebo. The treatment period will be 4-Weeks.
Minimum age: 18 Years.
Maximum age: N/A.
- Adult patients with pain for â¥ 3 months following onset of a herpes zoster rash
- Clinically significant intercurrent illness (e. g., endocrine, cardiac, hepatic, renal,
neurologic, hematologic, skeletal) that the investigator determines could interfere
with the efficacy or safety assessments.
