Clinical Details

Official title: A Randomized, Double-Blind, Parallel Group, Placebo-Controlled, Dose Ranging Study to Assess the Analgesic Efficacy, Tolerability, Safety and Pharmacokinetic/Pharmacodynamic Properties of A Sublingual Wafer Formulation of Ketamine Following Third Molar Extraction

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment

Primary outcome: Sum of Pain Intensity Difference

Secondary outcome:

Sum of Pain Intensity Difference

Safety and Tolerability evaluated by physical examination, vital signs, pulse oximetry, clinical laboratory tests, ECGs and Incident of Adverse Events (AEs) and Serious Adverse Events (SAEs).

Detailed description: This is a Phase 2, randomized, double-blind, parallel group, dose-ranging placebo-controlled evaluation of the analgesic efficacy, safety and pharmacokinetics of ketamine sublingual wafer in adult subjects who experience post-operative pain after undergoing third molar extraction. The study will enroll approximately 80 subjects at a single site. Subjects will be at least 18 years to 38 years of age. Subjects will receive a single dose of 70 mg or 100 mg sublingual ketamine wafer or placebo. Efficacy assessment will include pain intensity, use of rescue medication, and Patient Global Assessment (PGA) of pain control. Safety assessments will include monitoring of AEs and SAEs, clinical laboratory tests, vital sign measurements, oral assessments, and ECGs. A maximum of eight 4ml blood samples will be taken from each participant up to 8 hours after study drug administration for plasma analysis.


Minimum age: 18 Years. Maximum age: 38 Years. Gender(s): Both.


Healthy male and female subjects, ages 18-38 years old, who are scheduled to undergo two ipsilateral third molar extractions.
