Gilead Science Inc.'s oral targeted cancer drug, idelalisib (GS-1101), made a splash last week when the American Society of Clinical Oncology (ASCO) unveiled thousands of abstracts scheduled for presentation at next week's annual meeting in Chicago. In a press conference Wednesday afternoon, Jennifer R. Brown, director of the Chronic Lymphocytic Leukemia Center at the Dana-Farber Cancer Institute, provided Phase I findings suggesting idelalisib, as a single agent, has the potential to stave off the need for additional treatments for relapsed/refractory chronic lymphocytic leukemia (CLL).
