Sunesis Announces Amendment to Loan Agreement


SOUTH SAN FRANCISCO, Calif., March 2, 2015 (GLOBE NEWSWIRE) -- Sunesis Pharmaceuticals, Inc. (Nasdaq:SNSS) today announced the signing of an amendment to its loan and security agreement (the "Loan Agreement") with Oxford Finance LLC, Silicon Valley Bank, and Horizon Technology Finance Corporation (collectively, "the Lenders").

The amendment, effective February 27, 2015, creates an interest-only period from March 1, 2015 through February 1, 2016 on the remainder of Sunesis' loan balance. Principal payments will resume March 1, 2016. In consideration for the amendment, Sunesis will issue the Lenders warrants to purchase an aggregate of 61,467 shares of Sunesis common stock at an exercise price of $2.22 per share. Additionally, the final payment will be deferred by 12 months to the fourth quarter of 2016, and will be increased from 3.75% to 4.65% of the total loan amount, a difference of $225,000.  Sunesis entered into the $25 million Loan Agreement with the Lenders in October 2011.

"This amendment to our loan facility provides us with additional financial flexibility to execute our corporate strategy, including the potential submission in 2015 of U.S. and European filings for regulatory approval of vosaroxin in relapsed or refractory acute myeloid leukemia," said Eric Bjerkholt, Executive Vice President of Corporate Development and Finance and Chief Financial Officer of Sunesis. "We believe that this loan amendment, together with our current cash position, provide us with the resources to fund operations through the first quarter of 2016."
