A study in healthy volunteers to evaluate the safety, tolerability and pharmacokinetics of OCT461201. The study included a screening period, a single dose of study treatment or placebo and a follow up period.

A phase 1, randomised, double-blind, placebo-controlled study to evaluate the safety, tolerability, and pharmacokinetics of OCT461201 in healthy participants following ascending single doses.

The study comprised a screening period (Day -35 to Day -2), a treatment period (Day -1 to Day 3) and a post-study follow-up visit 4 - 8 days following administration of OCT461201 or placebo (i.e., Day 5 - 9). A dose leader design was implemented with 2 participants being dosed on the first dosing day (1 randomised to placebo, 1 to active drug) and the remainder of the cohort dosed at least 24 hours later pending an acceptable safety profile in the dose leader group. Safety and Pharmacokinetic data was reviewed by the Dose Escalation Review Committee before escalation to the next cohort/dose level.

Inclusion Criteria:

• Healthy male and female participant, between 15 and 55 years of age inclusive at screening
• Body mass index (BMI) of 18-30 kg/m2

• No clinically significant results for serum biochemistry, haematology and/or urine analysis within 35 days before first dose of Investigational Medicinal Product (IMP)
• No clinically significant abnormalities in 12-lead ECG within 35 days before dose of IMP
• Available to complete the study including all follow up visits

Exclusion Criteria:

• Clinically significant history of gastrointestinal disorder likely to influence IMP absorption
• Evidence of renal, hepatic, central nervous system, respiratory, cardiovascular or metabolic dysfunction
• Participation in a new chemical entity clinical study within the previous 3 months or 5 half-lives, whichever was longer

Double-blind, randomised study
