Infinity Reports First Quarter 2012 Financial Results

Infinity Pharmaceuticals, Inc.today reported its financial results for the first quarter of 2012. The company maintained its strong financial condition while continuing to advance its clinical programs during the quarter toward the key development milestones expected in the second half of 2012.

“We continue to anticipate important data readouts in the second half of 2012 from four of our six ongoing trials across three distinct development programs. Positive data in any of our programs have the potential to be significant for our company by providing a path to registration,” stated Adelene Q. Perkins, Infinity’s president and chief executive officer. “We ended the first quarter with nearly $105 million in cash and investments as well as $230 million in committed research and development funding. This strong financial foundation enables us to continue investing in discovery efforts to further enhance our pipeline while also advancing our development programs to key value inflection points before needing to finance.”
