Effects of Administration of Fostamatinib on Blood Concentrations of Rifampicin in Healthy Subjects.

July 21, 2011 updated by: AstraZeneca

An Open-Label, Non-Randomized, 2-Period, Single Center Study to Assess the Single Dose Pharmacokinetics of R406 in Healthy Subjects When Fostamatinib 150 mg is Administered Alone and in Combination With Rifampicin

The purpose of this study is to investigate the drug interaction between fostamatinib and rifampicin by comparing the safety, tolerability and plasma concentration of fostamatinib when administered alone and with rifampicin in healthy subjects

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Time Frame
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
Period 1: Day 1 to 96 hours post-dose Period 2: Day 6 to 96 hours post-dose

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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
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.
