Results and Recent Highlights
Sunesis to Host Conference Call Today at 11:00 AM Eastern Time
SOUTH SAN FRANCISCO, Calif., March 10, 2016 Sunesis Pharmaceuticals, Inc. (Nasdaq: SNSS) today reported financial results for the fourth
quarter and year ended December 31, 2015. Loss from operations for the three months and year ended December 31, 2015 was $11.3 million and $39.3 million, respectively. As of December 31, 2015, cash, cash equivalents and marketable
securities totaled $46.4 million.
In the fourth quarter, we achieved a top 2015 corporate milestone with the submission and validation of our
Marketing Authorization Application in Europe for vosaroxin to treat relapsed/refractory AML, said Daniel Swisher, Chief Executive Officer of Sunesis. We are committed to bringing this important new therapy to a patient population with
so few options. We will be providing updates later this year on the progress in Europe and in other major regions, including North America.
Mr. Swisher added: Another key milestone for Sunesis is the progress of our pipeline of kinase inhibitors representing targeted new approaches to
the treatment of cancer. Soon, we expect to initiate clinical development of SNS-062, our differentiated non-covalent BTK inhibitor with a European Phase 1A clinical trial in healthy volunteers, followed by a Phase 1B/2 in B-cell malignancy patients
later this year. We also look forward to seeing data from the ongoing multi-arm combination study for the Takeda-partnered pan-RAF inhibitor, TAK-580, and to advancing our PDK-1 inhibitor, SNS-229, through IND-enabling toxicology studies to an
