Primary Outcome Measures
NameTimeMethod
The percent of absolute bioavailability (F) of R406 after oral administration of fostamatinib.Up to 96 hours post dose
Total radioactivity of [14C] R406 after an intravenous infusion of [14C]R406 in terms of AUC, AUC(0-t), Cmax, t1/2λz, MRT, CL, Vz.Up to 96 hours post dose

AUC-Area under the plasma concentration time curve; AUC(0-t)-Area under plasma concentration time curve from zero to time of the last measurable concentration; Cmax - max plasma concentration; t½ λz-Terminal half-life; MRT- Mean residence time; CL - Total body clearance; Vz - Volume of distribution during the terminal phase

Pharmacokinetic (PK) profile of a single oral dose of fostamatinib and a radiolabelled intravenous micro tracer dose of [14C] R406.0, 30min, 1h, 1h 30min, 1h 45min, 1h 50min, 1h 55min, 2, 2h 5min, 2h 10min, 2h 15min, 2h30min, 3, 3h 30min, 5h30min, 9h, 12h, 18h, 24h, 30h, 48h, 72h, 96h post-dose

PK Parameters: AUC, AUC (0-t), Cmax, t½ λz and MRT
