What is the study measuring?
Primary Outcome Measures
Primary Outcome Measures
Outcome Measure |
Time Frame |
|---|---|
|
To assess the effects of repeated doses of Fostamatinib on the pharmacokinetics of Microgynon ®30 by assessment of Cssmax and AUCss of ethinyl estradiol (EE), levonorgestrel on Day 21
Time Frame: From predose until Day 22 of each Treatment period

From predose until Day 22 of each Treatment period

Secondary Outcome Measures
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
To characterise the PD of progesterone, LH, FSH, and SHBG, following dosing with monophasic oral contraceptive (Microgynon® 30) alone and following coadministration with fostamatinib
Time Frame: From predose until Day 22 of each Treatment period
|
PD = pharmacodynamics, LH = luteinising hormone, FSH = follicle stimulating, SHBG = Sex hormone binding globulin
|
From predose until Day 22 of each Treatment period
|
|
To determine R-406 plasma concentration-time profile and resulting PK parameters including AUCss, Cssmax, and tmaxss
Time Frame: From pre-dose until 12 hours following final dose on Day 21
|
From pre-dose until 12 hours following final dose on Day 21
|
|
|
To determine the safety and tolerability of fostamatinib in combination with an oral contraceptive (Microgynon ®30): adverse event monitoring, vital signs, physical examinations, clinical laboratory tests, ECGs
Time Frame: Screening, treatment periods 1 and 2, Follow up
|
Screening, treatment periods 1 and 2, Follow up
