Study Testing Ketamine Sublingual Wafer After Wisdom Tooth Extraction

Phase 2
Completed
Conditions
Pain
Interventions
Drug: Placebo (for Ketamine)
Registration Number
NCT02356965
Lead Sponsor
iX Biopharma Ltd.
Brief Summary

The purpose of the study is to test two different doses of ketamine sub-lingual (under the tongue) wafer against placebo to see how effective the medication is to treat moderate to severe pain after wisdom tooth extraction.

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.

Primary Outcome Measures
NameTimeMethod
Sum of Pain Intensity Difference3 hours

Demonstrate the dose-response relationship for analgesia of two dose levels of ketamine sublingual wafer compared with placebo, using the summed pain intensity difference from baseline over the first 3 hours (SPID3) in subjects with acute moderate to severe pain following third molar extraction.

Secondary Outcome Measures
