AstraZeneca has started the Phase III trials program for fostamatinib disodium (R788), a novel drug for rheumatoid arthritis licensed earlier this year from Rigel Pharmaceuticals.
Fostamatinib is a member of a new class of rheumatoid arthritis drugs called syk kinase inhibitors, and will be tested in three Phase III trials collectively known as the OSKIRA program. AstraZeneca said it hoped to be in a position to file for approval of the drug in 2013.
