An FDA rejection of Galapagos NV's rheumatoid arthritis (RA) drug filgotinib, announced Aug. 18, was "disappointing and unexpected," CEO Onno van de Stolpe said, adding that "there is so much more" to his company's story and pipeline. Gilead Sciences Inc., the Belgian company's partner and a substantial backer of both the drug and the pipeline, said it would "evaluate the points raised" by the CRL, but continued to believe in the drug.
