SANTA CLARA, Calif.--(BUSINESS WIRE)--May 6, 2010--XenoPort, Inc. (Nasdaq:XNPT) announced today its financial results for the first quarter ended March 31, 2010. Revenues for the quarter were $0.1 million, compared to $26.3 million for the same period in 2009. Net loss for the first quarter was $28.2 million, compared to a net loss of $2.7 million for the same period in 2009. At March 31, 2010, XenoPort had cash and cash equivalents and short-term investments of $123.3 million.

The following key events occurred since the beginning of the first quarter of 2010:

Ronald W. Barrett, Ph.D., chief executive officer of XenoPort, stated, “We have reshaped our business to focus our efforts on Horizant and on advancing our clinical-stage product candidates. We believe we have made good progress in identifying additional information that may be useful in the FDA’s further consideration of the Horizant NDA. We remain committed to addressing the unmet medical needs of RLS sufferers.”

Dr. Barrett added, “The tough decisions that we made this quarter are expected to reduce our cash usage. We now believe that our current cash will fund operations into the first quarter of 2012.”

Net revenue from unconsolidated joint operating activities for the first quarter of 2010 was $(0.3) million, compared to $22.9 million for the same period in 2009. The decrease in net revenue from unconsolidated joint operating activities for the first quarter of 2010 compared to the same quarter in the prior year was primarily due to the receipt and recognition of a significant portion of the $20.0 million milestone payment from GSK related to the FDA’s acceptance for review of the Horizant NDA in the three months ended March 31, 2009 and, to a lesser extent, the recognition of XenoPort’s share of pre-launch operating losses of Horizant.

Collaboration revenue was $0.4 million for the first quarter of 2010, compared to $3.4 million for the same period in 2009. The decrease in collaboration revenue for the first quarter of 2010 compared to the same period in 2009 was the result of a decrease in revenue recognized from a milestone payment under our agreement with Astellas Pharma Inc.

Research and development expenses for the first quarter of 2010 were $15.1 million, compared to $21.8 million for the same period in 2009. The decrease in expenses for the quarter was primarily due to decreased development activities for Horizant/XP13512, AP, XP21279 and preclinical programs, as well as decreased personnel costs due to reduced headcount and lower non-cash stock-based compensation.

Selling, general and administrative expenses remained relatively constant at $8.1 million for the first quarter of 2010, compared to $7.7 million for the same period in 2009.

In the first quarter of 2010, XenoPort recorded a $5.3 million charge resulting from the implementation of a restructuring plan that was precipitated by the Complete Response letter from the FDA. Of the $5.3 million charge, approximately $4.0 million represents cash expenditures, of which $1.0 million was paid in the first quarter of 2010. XenoPort is currently completing its facilities assessment and may incur additional facility-related charges pending the completion of this assessment.

Net loss for the first quarter of 2010 was $28.2 million, compared to a net loss of $2.7 million for the same period in 2009. Basic and diluted net loss per share was $0.93 for the first quarter of 2010, compared to $0.10 for the same period in 2009.

XenoPort announced that it expects the net use of cash for 2010 to be in the range of $72 million to $82 million (net use of cash is the difference between the balances of cash and cash equivalents plus short-term investments at 12/31/10 and 12/31/09).
