Description of intervention(s) / exposure
The intervention for this study, CRN00808, is an orally bioavailable small molecule somatostatin receptor agonist that lowers hormone levels in acromegaly patients. CRN00808 will be administered as a 2 x 10mg capsules for a total dose of 20mg in all four periods.
This study consists of 4 administration conditions:
Condition A: Subjects will remain fasting for 4 hours after drug administration.
Condition B: Subjects will remain fasting for 2 hours after drug administration.
Condition C: Subjects will remain fasting for 1 hour after drug administration.
Condition D: Subjects will receive a standard dinner then fast for 2 hours prior to drug administration. After dosing, the subject will fast overnight.
Subjects will be directly observed by study personnel to ensure that the fasting requirements are adhered to. The Condition D standard dinner will be nutritionally identical for all subjects, however the meal may differ to accommodate subjects with dietary requirements, such as; vegetarian, vegan and gluten free.
There will be up to 12 subjects enrolled in this study. All subjects will be administered study drug under each of the four conditions. There will be 8 days between treatment administration for each condition.
Subjects will undergo Condition A, B and C in a randomised order. Condition D will be completed by all subjects after completion of Condition A, B and C.

Outcomes
Primary outcome [1] 306930 0
Pharmacokinetics parameters (AUC, Cmax, Tmax, Tlag and T1/2) following single doses of CRN00808 in male and female subjects derived from plasma concentrations of CRN00808.
Timepoint [1] 306930 0
PK Plasma sampling, collected at the following timepoints;
15 mins pre-dose, 15 mins, 30 mins, 45 mins, 1 hr, 1.25 hr, 1.5 hr, 2.0 hr, 3.0 hr, 4.0 hr, 6.0 hr, 8.0 hr, 10 hr, 12 hr, 18 hr, 24 hr, 72 hr, 120 hr post dosing in each period. A final sample will also be collected on Day 33.
Secondary outcome [1] 350147 0
Safety and tolerability of single doses of CRN00808 in male and female subjects based on clinical laboratory tests, triplicate ECGs, vital signs, physical exams and adverse events.
Timepoint [1] 350147 0
Clinical laboratory tests including chemistry, haematology and urinalysis at the following time points;
Screening, Check in, Day 2 post dose and Day 6 post dose for each period. Clinical laboratory tests will also be performed at Day 33.
triplicate ECGs at the following timepoints;
Screening, check in, pre-dose, 3.0 hrs, and 24 hrs post dose for each period, Triplicate ECGs will also be performed on Day 33.
Vital signs at the following timepoints;
Screening, check in, predose, 1.5 hrs, 3.0 hrs, 6.0 hrs and 24 hrs post-dose for each period. Vital signs will also be performed on Day 33.
Physical exams at the following timepoints;
Screening, check in for every period and on Day 33.
Adverse events will be recorded from the time that a subject signs consent until the final follow up visit on day 33. Site staff will question subjects on their health when conducting other assessments throughout the trial. Adverse events will be assessed by study investigators. Adverse events known to be associated with somatostatin receptor agonists include abdominal pain, diarrhea, and nausea.
