Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
EMA401 powder hand-filled into hard gelatin capsules.
4 out of 6 subjects in each cohort will take a single oral dose of the EMA401 following an overnight fast. There are 6 cohorts with dose levels of 100mg, 200mg, 400mg, 600mg, 800mg, 1000mg. One dose level (cohort) will be asked to return to repeat the study with the drug being taken following a standard meal. There will be 6 subjects per cohort, 2 receiving placebo and 4 receiving the active drug.

There are 6 cohorts with dose levels for the active drug of 100mg, 200mg, 400mg, 600mg, 800mg, 1000mg. One dose level (cohort) will be asked to return to repeat the study with the drug being taken following a standard meal. There will be 6 subjects per cohort, 2 receiving placebo and 4 receiving the active drug.

Outcomes
Primary outcome [1] 4335 0
To evaluate the safety and tolerability of a single dose of EMA401
Timepoint [1] 4335 0
Vital signs (x10), clinical laboratory results(x6) and Electrocardiograms (ECGs) (x12) will be recorded over a 48 hour time period post dose and 24 hour cardiac telemetry for the first 24 hours post-dose. Vital signs measurements include resting heart rate, Blood Pressure readings, respiratory rate and body temperature recording. The clinical laboratory results will be from blood samples taken at the screening visit, the day prior to dosing, at 4, 24 and 48 hours post-dose and again at the follow up visit, 7 days post-dose. Adverse events and concomitant medications required will be monitored over the 48 hour time period post dose. A final follow up evaluation including a physical examination will be performed 7 days post dose.
Secondary outcome [1] 7307 0
To determine the pharmacokinetic profile of EMA401 following a single oral dose in healthy fasting volunteers.
Timepoint [1] 7307 0
1 x pre-dose and 18 post-dose blood samples will be collected over a 48 hour period. Urine will be collected for 24 hours post-dose. Both blood and urine samples will be analysed to profile the pharmacokinetics.
Secondary outcome [2] 7308 0
To determine the effects of food on the pharmacokinetics of EMA401 following a single oral dose in healthy volunteers.
Timepoint [2] 7308 0
Dosing will be repeated in one dose level, with dosing occurring after a standard meal. 1 x pre-dose and 18 post-dose blood samples will be collected over a 48 hour period. Urine will be collected for 24 hours post-dose. Both blood and urine samples will be analysed to profile the food-effect pharmacokinetics.

Eligibility
Key inclusion criteria
Healthy subjects- defined as individuals who are free from clinically significant illnesss or disease as determined by their medical / surgical history, physical examination (including height & weight), 12 lead electrocardiogram (ECG) and clincial laboratory determinations.
Normotensive - Systolic between 90 and 140 mmHg, diastolic between 60 & 90 mmHg.
No clincially relevant abnormality in an electrocardiogram (ECG) - QTc < 450ms, PR interval 120-210 ms, QRS duration <100ms. (QTc = QT interval corrected for heart rate, where QT = a measure of the time between the start of the Q wave and the end of the T wave in the heart's electrical cycle, PR interval = measured from the beginning of the P wave to the beginning of the QRS complex and QRS duration (complex) = a structure on the ECG that corresponds to the depolarization of the ventricles.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Subjects will be allocated a sequentially numbered randomisation number following confirmation of eligibility on day -1 and the Screening visit results. The randomisation number will be matched to the treatment allocation from a randomisation schedule which is computer generated and maintained under controlled access. The subject and all clinical staff will be blinded to the treatment allocation. Only the unblinded staff members involved in the drug dispensing will be aware of the treatment allocation. Emergency codebreak envelopes are stored securely at the site should an emergency situation require the knowledge of what treatment the subject received.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation computer generated block randomisation per cohort.
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
