Primary Outcome Measures:

To assess the pharmacokinetics of R406 in healthy subjects when a single dose of fostamatinib is administered alone and in combination with rifampicin. AUC and Cmax will be measured [ Time Frame: Period 1: Day 1 to 96 hours post-dose Period 2: Day 6 to 96 hours post-dose ]

Secondary Outcome Measures:

To assess the pharmacokinetics of R406 in healthy subjects when a single dose of fostamatinib is administered alone and in combination with rifampicin. AUC (0-t), terminal half life, and tmax will be measured [ Time Frame: Period 1: Day 1 to 96 hours post-dose Period 2: Day 6 to 96 hours post-dose ]
To examine the safety and tolerability of fostamatinib in combination with rifampicin. [ Time Frame: From screening, Day 1 - Day 25, up to follow up visit ]
Assessments include: Adverse events, laboratory assessments, vital signs, physical examination and 12-lead electrocardiogram. Absolute values and change in baseline for any of these parameters will be reported.
