The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details.
Information provided by:
A 2 stage study to evaluate the amount of fostamatinib in the blood and urine in subjects with impaired kidney (renal) function compared with healthy volunteers with normal renal function. Stage 1 will include healthy subjects and subjects with end stage renal disease, while Stage, 2 may include subjects with mild, moderate and/or severe renal impairment dependent on the outcome of Stage 1. The study will also evaluate safety and tolerability in subjects with renal impairment.

Condition Intervention Phase
Rheumatoid Arthritis Renal Impairment Drug: fostamatinib Phase 1

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Basic Science
Official Title: An Open-label, Phase I Study to Assess the Pharmacokinetics of R406 in Subjects With Renal Impairment Compared to Healthy Subjects Following Administration of a Single Dose of Fostamatinib 150 mg
