  Purpose

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


Condition Intervention Phase
Rheumatoid Arthritis
Healthy Volunteers
 Drug: fostamatinib
Drug: rifampicin
 Phase 1

Study Type: Interventional

Endpoint Classification: Safety Study
Intervention Model: Crossover Assignment
Masking: Open Label
Primary Purpose: Basic Science
Official Title: 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

Further study details as provided by AstraZeneca:

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 ] [ Designated as safety issue: No ]

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 ] [ Designated as safety issue: No ]
  • 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 ] [ Designated as safety issue: Yes ]
    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.
