(NASDAQ: ARIA) today reported financial results for the second quarter and six months ended June 30, 2012 and provided an update on corporate developments.

“The second quarter of 2012 was a highly productive time for ARIAD,” stated ., chairman and chief executive officer of ARIAD. “We are executing effectively within all areas of the company with our development programs for ponatinib and AP26113 moving forward either ahead of schedule or as planned, and momentum is building for U.S. and European launch of ponatinib in 2013. This is an exciting time at ARIAD as we build a global commercial oncology company based on our internally discovered product candidates.”

At June 30, 2012, cash, cash equivalents and marketable securities totaled $250.3 million, compared to $306.3 million at December 31, 2011.

Net loss for the quarter ended June 30, 2012, was $51.3 million, or $0.31 per share, compared to a net loss of $47.8 million, or $0.36 per share, for the same period in 2011. For the six month period ended June 30, 2012, net loss was $107.2 million, or $0.66 per share, compared to a net loss of $85.7 million, or $0.66 per share, for the same period in 2011.

Research and development expenses increased by $20.7 million from the second quarter of 2011 to the second quarter of 2012 and by $34.9 million from the first half of 2011 to the first half of 2012 reflecting expansion of development activities for ponatinib, including an increase in personnel expenses to support those activities. In addition, research and development expenses in the second quarter of 2012 included a charge of $4.8 million to write down the carrying value of intangible assets related to ridaforolimus following the Complete Response Letter issued by the FDA in June 2012 to the NDA filed by Merck & Co., Inc. for ridaforolimus in patients with sarcomas.

General and administrative expenses increased by $6.1 million from the second quarter of 2011 to the second quarter of 2012 and by $12.5 million from the first half of 2011 to the first half of 2012 due to growth in commercial operations and supporting activities in anticipation of potential regulatory approval and commercial launch of ponatinib.

ARIAD’s net loss for the first half of 2012 also reflects a charge of $15.9 million, taken in the first quarter of 2012, related to the revaluation of our warrant liability, compared to a charge of $41.5 million for the first half of 2011, due to increases in the market price of our common stock during those periods.

As a result of not receiving the $25 million milestone payment from Merck related to U.S. approval of ridaforolimus in the sarcoma indication, offset in part by reduced expenses, financial guidance for 2012 is being updated.

ARIAD expects cash used in operations for 2012 to be in the range of $162 million to $167 million. ARIAD expects cash, cash equivalents and marketable securities at December 31, 2012 to be in the range of $142 million to $147 million. ARIAD estimates that current cash, cash equivalents and marketable securities are sufficient to fund operations to the fourth quarter of 2013.
