Sunesis Pharmaceuticals Reports First Quarter 2010 Financial Results

04/29/10

SOUTH SAN FRANCISCO, CA, Apr 29, 2010 (MARKETWIRE via COMTEX News Network) -- Sunesis Pharmaceuticals, Inc. (NASDAQ: SNSS) today reported financial results for the first quarter ended March 31, 2010. Net loss was $4.6 million for the first quarter of 2010. As of March 31, 2010, Sunesis had cash and cash equivalents of $14.7 million.

"Since the beginning of the year, we have made significant progress with our regulatory and clinical efforts for voreloxin, paving the way for the launch of our Phase 3 pivotal trial in patients with relapsed or refractory acute myeloid leukemia (AML) in the second half of 2010," said Daniel Swisher, Chief Executive Officer of Sunesis. "We believe voreloxin represents one of the most promising anticancer compounds in development for the treatment of AML, and the outcomes of our productive meetings with the FDA have provided a clear registration path for voreloxin in this indication. We are now focused on finalizing preparations for the Phase 3 trial and look forward to sharing updated data from our fully enrolled Phase 2 AML and ovarian cancer trials at ASCO in June."

Recent Highlights

--  Upcoming presentations at ASCO.  In April, Sunesis announced that
    three abstracts have been accepted for presentation on June 7 at the
    2010 American Society of Clinical Oncology (ASCO) Annual Meeting in
    Chicago, which runs from June 4-8. The presentations include an oral
    presentation of final data from the Company's Phase 2 trial of
    voreloxin in ovarian cancer, as well as poster presentations and
    discussion sessions of maturing data from its two Phase 2 studies of
    voreloxin in AML.


--  Milestone meetings with the FDA and EMA.  In February, Sunesis
    announced that it completed formal End-of-Phase 2 meetings with the
    U.S. Food and Drug Administration (FDA) related to voreloxin in AML.
    Based on the development clarity achieved as a result of these
    meetings, the Company intends to proceed with its plan to conduct a
    randomized, double-blind, placebo-controlled, pivotal Phase 3 trial
    evaluating voreloxin in combination with cytarabine, a widely used
    chemotherapy, in patients with first relapsed or primary refractory
    AML. Sunesis also reported that, as part of its global development
    strategy, a pre-submission meeting has been held with the European
    Medicines Agency (EMA) to obtain the EMA's scientific advice on the
    development program for voreloxin, including the proposed Phase 3
    trial, later this quarter.


--  Completion of enrollment in Phase 2 voreloxin combination trial.  In
    January, the Company reported the completion of enrollment in its
    Phase 1b/2 clinical trial evaluating voreloxin in combination with
    cytarabine in patients with relapsed or refractory AML.  This study
    serves as the basis for the Company's planned Phase 3 trial.


--  Outlicensing of proprietary drug discovery technology. In February,
    Sunesis granted Carmot Therapeutics, Inc. an exclusive license to its
    proprietary Fragment-Based Lead Discovery technology, "Chemotype
    Evolution," for use in identifying promising drug candidates in a
    broad range of therapeutic areas, including inflammatory, metabolic
    and neurodegenerative diseases. Sunesis retains full rights to the
    technology for use in its future internal discovery efforts.



Financial Highlights

--  In January, Sunesis entered into a controlled equity offering sales
    agreement with Cantor Fitzgerald & Co. pursuant to which the
    Company could issue and sell shares of common stock from time to time
    with aggregate proceeds of up to $15.0 million. As of March 31, 2010,
    Sunesis had utilized the full facility with 15.9 million shares of
    common stock sold raising gross proceeds of $15.0 million. Net
    proceeds after expenses and commissions were $14.2 million.


--  Revenues for the three months ended March 31, 2010 were $12,500
    compared to $0.2 million for the same period in 2009. Revenue in the
    2009 period was primarily related to the sale of compound libraries
    that were not core to the Company's ongoing development efforts.


--  Research and development expenses decreased to $3.1 million for the
    three months ended March 31, 2010, as compared to $4.3 million for the
    same period in 2009. The decrease of $1.2 million between the three
    month periods was primarily due to decreases in clinical expenses,
    outside services and facility costs.


--  General and administrative expenses for the three months ended March
    31, 2010 were $1.6 million as compared to $2.4 million for the same
    period in 2009. The decrease was primarily due to reduced
    administrative headcount from the March 2009 restructuring and reduced
    facility costs.


--  Sunesis reported net losses of $4.6 million for the three months ended
    March 31, 2010, as compared to net losses of $8.4 million for the same
    period in 2009.


--  Cash used in operations was $3.7 million for the three months ended
    March 31, 2010, as compared to $6.6 million for the same period in
    2009.



About Voreloxin

Voreloxin is a first-in-class anticancer quinolone derivative, or AQD, a class of compounds that has not been used previously for the treatment of cancer. Voreloxin both intercalates DNA and inhibits topoisomerase II, resulting in replication-dependent, site-selective DNA damage, G2 arrest and apoptosis. Voreloxin is currently being evaluated in a fully enrolled single agent Phase 2 clinical trial (known as the REVEAL-1 trial) in previously untreated elderly AML patients and in a fully enrolled Phase 1b/2 clinical trial combining voreloxin with cytarabine for the treatment of patients with relapsed/refractory AML. A Phase 2 single agent trial in platinum-resistant ovarian cancer has also completed enrollment. Sunesis anticipates initiating a Phase 3 trial of voreloxin in AML in the second half of 2010.

About the Pivotal Phase 3 Trial

Sunesis anticipates initiating a Phase 3, randomized, double-blind, placebo-controlled, pivotal trial in patients with first relapsed or primary refractory AML in the second half of 2010. The trial is designed to evaluate approximately 450 patients, multi-nationally, including leading sites in the U.S. and Europe. Patients are expected to be randomized one to one to receive either voreloxin (90 mg/m2) on days one and four in combination with cytarabine (1 g/m2) daily for five days, or placebo in combination with cytarabine. The study's primary endpoint is overall survival.

About Acute Myeloid Leukemia

AML is a rapidly progressing cancer of the blood characterized by the uncontrolled proliferation of immature blast cells in the bone marrow. The National Cancer Institute estimated that nearly 13,000 new cases of AML were diagnosed and approximately 9,000 deaths from AML occurred in the U.S. in 2009. Additionally, it is estimated that prevalence of AML is approximately 25,000 in the U.S. 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.

About Ovarian Cancer

In the United States, ovarian cancer remains the leading cause of death from gynecologic malignancies and is the fifth leading cause of cancer death overall in women behind lung, breast, colorectal and pancreatic cancers. According to the American Cancer Society, in 2009 there were an estimated 21,550 new cases and more than 14,000 deaths from ovarian cancer in the U.S. alone. Following frontline treatment, recurrence rates among ovarian cancer patients are high. Treatment options remain limited following relapse, and overall long-term survival has not changed significantly over the past 40 years in women with recurrent disease, with less than 30 percent of patients surviving for more than five years.
