First Quarter 2012 and Recent Highlights

  Continued strong execution of VALOR trial. Enrollment and execution in the VALOR trial continues to be strong, with 317 patients enrolled as of yesterday, which remains on track for the conduct of the interim analysis in the third quarter of this year.

  Announced $25.0 million vosaroxin royalty agreement with Royalty Pharma. In March, Sunesis announced that Royalty Pharma agreed to pay Sunesis $25.0 million, under certain circumstances related to the successful development of vosaroxin, to acquire a royalty on future worldwide net sales of vosaroxin on terms and conditions previously disclosed.

  Granted U.S. patent covering vosaroxin compositions. In March, the U.S. Patent and Trademark Office granted Sunesis Patent No. US 8,138,202 B2 covering certain compositions related to vosaroxin, which provides patent exclusivity through mid-2030 in the United States. A family of corresponding patent applications is pending internationally.

  Received orphan drug designation by European Commission.In April, the European Commission granted orphan drug designation to vosaroxin for the treatment of acute myeloid leukemia (AML). The designation provides for 10 years of marketing exclusivity subsequent to product approval in Europe. Vosaroxin has previously received orphan drug and fast track designations from the U.S. Food and Drug Administration.

In April, Millennium Pharmaceuticals, Inc. presented preclinical data on MLN2480 at the 2012 American Association of Cancer Research Annual Meeting in Chicago. The data suggest that MLN2480 has therapeutic anti-cancer activity in both B-Raf mutant and wild-type melanoma tumor models.

  Dosed first patient in Cardiff University sponsored Less Intensive 1 (LI-1) Trial. In March, patient dosing began in the Cardiff University sponsored Phase 2/3 randomized, controlled, multicenter LI-1 Trial, which is evaluating novel treatment regimens, including two regimens containing vosaroxin, against low dose cytarabine in elderly AML or high-risk myelodysplastic syndrome (MDS) patients who are not candidates for intensive chemotherapy.

  VALOR design poster presentation accepted for ASCO 2012.

Financial Highlights

  Cash, cash equivalents and marketable securities totaled $34.9 million as of March 31, 2012, as compared to $44.1 million as of December 31, 2011.

  Total revenue was nil for the three months ended March 31, 2012, as compared to $4.0 million for the same period in 2011. Revenue in the 2011 period was due to an upfront payment of $4.0 million from Millennium Pharmaceuticals, Inc. as part of the assignment of licenses for two oncology programs to it in March 2011.

  Research and development expenses increased to $6.6 million for the three months ended March 31, 2012, as compared to $4.1 million for the same period in 2011. The increase in 2012 was primarily due to an increase in clinical and other expenses related to the VALOR trial.

  General and administrative expenses for the three months ended March 31, 2012 were $2.2 million, as compared to $2.0 million for the same period in 2011. The increase in 2012 was primarily due to higher non-cash stock-based compensation expenses.

  Other expense, net, was $4.8 million for the three months ended March 31, 2012, as compared to net other income of $3.9 million for the same period in 2011. Net other expense for the 2012 period was primarily comprised of a non-cash expense of $4.9 million for the revaluation of warrants issued in the underwritten offering completed in October 2010 to their fair value as of March 31, 2012.

  Sunesis reported a net loss of $13.9 million for the three months ended March 31, 2012, as compared to net income of $1.8 million for the same period in 2011.

VALOR is a Phase 3, randomized, double-blind, placebo-controlled, pivotal trial in patients with first relapsed or refractory AML. The trial is expected to enroll 450 evaluable patients at more than 110 leading sites in the U.S., Canada, Europe, Australia and New Zealand. The VALOR trial is currently enrolling patients, who are randomized one to one to receive either vosaroxin on days one and four in combination with cytarabine daily for five days, or placebo in combination with cytarabine. Additionally, the VALOR trial employs an innovative, adaptive trial design that allows for a one-time sample size adjustment by the Data Safety Monitoring Board (DSMB) at the interim analysis to maintain adequate power across a broader range of survival outcomes. The trial's primary endpoint is overall survival. For more information on the VALOR trial, please visit

About Vosaroxin

Vosaroxin is a first-in-class anti-cancer quinolone derivative (AQD), a class of compounds that has not been used previously for the treatment of cancer. Vosaroxin both intercalates DNA and inhibits topoisomerase II, resulting in replication-dependent, site-selective DNA damage, G2 arrest and apoptosis.

About AML

AML is a rapidly progressing cancer of the blood characterized by the uncontrolled proliferation of immature blast cells in the bone marrow. The American Cancer Society estimates there will be approximately 13,780 new cases of AML and 10,200 deaths from AML in the U.S. in 2012.  Additionally, it is estimated that the prevalence of AML across major global markets (U.S., France, Germany, Italy, Spain, United Kingdom, and Japan) is over 50,000. AML is generally a disease of older adults, and the median age of a patient diagnosed with AML is about 67 years. AML patients with relapsed or refractory disease and newly diagnosed AML patients over 60 years of age with poor prognostic risk factors typically die within one year, resulting in an acute need for new treatment options for these patients.
