Description of intervention(s) / exposure
This is a phase 1, randomised, double-blind, placebo-controlled study to investigate the safety, tolerability, and pharmacokinetics of topically administered NeuroDirect Ketamine in a single-ascending dose study in adult healthy volunteers between 18-60 years of age, to establish the recommended phase 2 dose (RP2D).
The study plans to test single doses of NeuroDirect Ketamine of 25 mg (Cohort 1), 50 mg (Cohort 2), and 100 mg (Cohort 3). The decision to progress from Cohort 1 to Cohort 2 and Cohort 2 to Cohort 3 will be based on safety and tolerability by the SRC. A similar sequence will follow for subsequent progression decisions by the SRC for all the cohorts.
Each cohort will consist of 8 participants (6 participants receiving NeuroDirect Ketamine and 2 participants receiving placebo).
1 ml of single dose of either study drug or placebo applied via topical administration to back of neck at the hairline and below between C3 and C4 vertebrae. The Investigator or designee is responsible for the education of study staff as to the correct administration of the study drug. Study staff will apply the product topically to the participant under direct supervision of Investigator.

Continuous variables will be summarised by dose and visit (where applicable), including the number of participants, mean, median, standard deviation, minimum, and maximum. Categorical endpoints will be summarised using the number of participants with frequency counts and percentages.
For each treatment plasma, CSF, and urine concentrations or ketamine and norketamine will be tabulated and summarised by treatment and nominal time using descriptive statistics which include, but are not limited to: number of subjects, arithmetic mean, standard deviation, coefficient of variation, geometric mean, median, minimum and maximum.
If analytical data permit, the following PK parameters for ketamine and norketamine will be calculated:
