Total operating expenses for the fourth quarter of 2012 were $2.4 million, compared with total operating expenses of $1.3 million for the fourth quarter of 2011.

The Company’s net loss for the fourth quarter of 2012 was $2.5 million, or $0.01 per share, compared with a net loss of $1.5 million, or $0.01 per share, for the same period in 2011. Full Year Results Revenues for the year ended December 31, 2012 were $1.0 million, compared with revenues of $0.8 million in 2011. The increase in revenue was due to higher royalty payments from Zogenix, Inc. for the SUMAVEL® DosePro™ (sumatriptan injection) needle-free delivery system. Total operating expenses for 2012 were $7.7 million, compared with total operating expenses of $9.3 million in 2011. Research and development expenses decreased by $1.2 million and general and administrative expenses decreased by $0.4 million. The decrease in research and development expenses reflects the completion of the ORBIT-1 bronchiectasis clinical trial of the Company’s inhaled ciprofloxacin product candidate. The decrease in general and administrative expenses was primarily due to lower executive bonus expense. The net loss for the year ended December 31, 2012 was $8.2 million, or $0.04 per share, compared with a net loss of $9.3 million, or $0.05 per share, in 2011. The net loss reduction was primarily due to the increase in royalty revenue and the reduction in operating expenses, partially offset by higher interest expense from the royalty financing transaction.
