Study Stopped
Only Part 1 was conducted but not Part 2. Due to the low exposures, definitive safety conclusions could not be made for the targeted exposure levels in the future.

Outcome Measures
Primary Outcomes (1)
(Part 1)To investigate the safety and tolerability of single oral doses of SP-8356 in healthy male subjects
Incidence of adverse events (AEs), and assessment of physical examinations, safety laboratory tests, vital signs, electrocardiograms (ECGs) and ophthalmologic examinations
up to 3days
Secondary Outcomes (4)
(Part 1)To characterise the pharmacokinetic (PK) profile of single oral doses of SP-8356 Maximum Observed Drug Concentration (Cmax)
up to 3days
(Part 1)]To characterise the pharmacokinetic (PK) profile of single oral doses of SP-8356- Area under the plasma concentration versus time curve from time zero to infinity (AUC[0-∞])
up to 3days
(Part 1)To characterise the effect of food on the PK profile of SP-8356 following single oral doses of SP-8356 Maximum Observed Drug Concentration (Cmax)
up to 3days

Study Arms (2)
SP-8356 powder
EXPERIMENTALPart1 will consist of escalating single doses in five sequential cohorts. Each dose level cohort will consist of 8 subjects: 6 subjects will receive SP-8356 and 2 subjects will receive placebo in fasted state according to the randomization schedule. Subjects in Cohort 3 will receive a single dose of SP-8356 or placebo in the fasted then fed state on separate dosing occasions.
