Study Details

A crossover study to assess the effect of repeated doses of fostamatinib on the levels of oral contraceptive (Microgynon® 30) in the blood of healthy female subjects. The study will consist of a screening period of up to 35 days, followed by 2 treatment periods (28 days each) of an oral contraceptive (Microgynon® 30) in the absence and presence of fostamatinib. The study will also evaluate the safety and tolerability of fostamatinib in combination with an oral contraceptive
