Arm && Interventions

Group	Intervention	Description
RV521	RV521	Three single 200 mg oral doses of RV521 administered on Day 1, Day 5 and Day 9 as either the drug in capsule (1 dosing occasion) or the dry powder blend dispersed in water (2 dosing occasions)

Primary Outcome Measures

Name	Time	Method
Maximum observed plasma concentration (Cmax) for RV521	Baseline to study day 11
Terminal half life (t1/2) for RV521	Baseline to study day 11
Area under the plasma concentration-time curve from time zero to last detectable plasma concentration (AUC0-t) for RV521	Baseline to study day 11
Time to maximum plasma concentration (tmax) for RV521	Baseline to study day 11
Area under the plasma concentration-time curve from time zero to infinity (AUC0-inf) for RV521	Baseline to study day 11

Secondary Outcome Measures

Name	Time	Method
Incidence of treatment emergent adverse events as assessed by CTCAE V5.0	Screening to final study visit (performed at 7 days following the last dose of any intervention)
Proportion of subjects with clinically significant changes in laboratory safety tests (haematology, chemistry, coagulation and urinalysis)	Screening to final study visit (performed at 7 days following the last dose of any intervention)
Proportion of subjects with morphological and/or rhythm abnormalities on ECG	Screening to final study visit (performed at 7 days following the last dose of any intervention)
Proportion of subjects with clinically significant changes in ECG time intervals (PR, QRS, QT and QTc intervals)	Screening to final study visit (performed at 7 days following the last dose of any intervention)
Proportion of subjects with clinically significant changes in vital signs (systolic blood pressure, diastolic blood pressure and pulse rate)	Screening to final study visit (performed at 7 days following the last dose of any intervention)
