Optimer Pharmaceuticals Reports First Quarter 2011 Financial Results

SAN DIEGO, May 5, 2011 /PRNewswire/ -- Optimer Pharmaceuticals, Inc. (NASDAQ: OPTR) today announced its financial results for the quarter ended March 31, 2011.

Optimer reported net income for the first quarter of 2011 of $45.1 million, or $1.06 and $1.04 per basic and diluted share, respectively, as compared to a net loss for the first quarter of 2010 of $13.5 million, or ($0.39) per share on both a basic and diluted basis.  The increase in net income was primarily due to licensing revenue from a $69.2 million upfront payment received from Astellas Pharma in connection with the DIFICID™ collaboration and license agreement. The increase was partially offset by a $10.4 million increase in operating expenses, including $4.3 million in licensing costs due to a royalty payment to Par Pharmaceutical associated with the Astellas upfront payment.

In addition, marketing expenses for the first quarter of 2011 increased $3.2 million compared to the prior year period due to market research and pre-commercialization efforts related to the DIFICID program.  General and administrative expenses increased $5.9 million compared to the first quarter of 2010 due to increases in consulting expenses and advisory fees related to DIFICID collaborations, increases in compensation expense, including a $1.0 million increase in stock compensation expense, and increased headcount, including the establishment of a market access team.  Research and development expenses decreased $2.9 million compared to the first quarter of 2010 due to a $5.0 million milestone payment in the prior year due to Par for the successful completion of the second DIFICID Phase 3 trial offset by an increase in medical affairs and publication expenses.

As of March 31, 2011, Optimer held cash, cash equivalents and short-term investments of $180.1 million.

"Optimer was extremely productive in the first quarter of 2011. We participated in a highly successful FDA Advisory Committee meeting, wherein we secured a unanimous vote supporting the safety and efficacy of DIFICID for the treatment of CDI. We also entered into collaboration agreements with Astellas in Europe and other countries to market DIFICID and with Cubist in the U.S. to co-promote DIFICID.  We believe this will help us maximize the impact of a potential DIFICID commercial launch," said Pedro Lichtinger, President and CEO of Optimer. "We continue to work with the FDA as it considers our DIFICID NDA and we look forward to the FDA's decision on our NDA by the May 30th PDUFA date. Meanwhile, we are continuing to build our commercial team and marketing program with the goal of positioning for a successful product launch pending FDA approval."
