Total operating expenses were $16.0 million and $55.4 million, including non-cash stock-based compensation expense of $0.6 million and $3.2 million, for the quarter and year ended December 31, 2007, compared to $10.9 million and $45.0 million for the same periods last year. Research and development expenses were $13.9 million for the quarter ended December 31, 2007, compared to $8.8 million in the same period in 2006. The increase for the fourth quarter is primarily due to increased clinical costs in the Hsp90 inhibitor and epothilone programs, including costs associated with the initiation of the clinical trials in the TIME registration program in multiple myeloma and preparation for the KOS-1584 Phase 2 clinical program. General and administrative expenses were $2.1 million for the quarter ended December 31, 2007, compared to $2.1 million in the same period in 2006.
