This study in healthy volunteers aims to identify safe single doses of PCN-101 administered IV; to assess how the body handles IV PCN-101; and to compare the safety of PCN-101 and esketamine. The study aims to identify tolerable dosing of IV PCN-101 to be evaluated in future clinical trials.
Part 1 of the study is an ascending dose, double-blind safety and tolerability study of single doses of IV PCN-101. Up to 48 healthy volunteers will be enrolled to receive a single dose of PCN-101 or placebo, as an infusion over 40 minutes.
Part 2 is a double-blind, cross-over safety and tolerability study comparing a single dose of PCN-101 versus esketamine, both given IV over 40 minutes. Ten healthy volunteers will be randomized into one of two treatment groups.
Group 1 will receive a single infusion of PCN-101 and then an infusion of esketamine. In Group 2, the order of infusions will be reversed. Safety will be assessed via vital signs, 12-lead ECG, clinical laboratory tests, neuropsychological scales, sedation and adverse events.
Trial Details
Part 1 is a randomised, placebo-controlled, double-blind, safety and tolerability study of single ascending doses of PCN-101 administered via intravenous (IV) infusions over 40 minutes to healthy volunteers. A total of up to 48 healthy volunteers will be enrolled in Part 1. The study will evaluate safety, tolerability and pharmacokinetics (PK) of PCN-101. The starting dose is 5mg (cohort 1) and this will be escalated in each subsequent cohort (15mg, 30mg, 60mg, 100mg and 150mg) Part 2 is a double-blind, crossover relative safety and tolerability study comparing a single dose of PCN-101 to esketamine. A total of 10 healthy volunteers will be randomised into one of 2 treatment groups. Treatment Group 1 will receive a single IV infusion over 40 minutes of PCN-101, then 48-hours later will receive a second IV infusion of esketamine. In Treatment Group 2, the order of infusions will be reversed. Part 2 will use the identified dose from Part 1 for PCN-101 and 15mg esketamine .Trial Number PA7
