BTK Inhibitor SNS-062 Licensed from Biogen Idec;
IND Anticipated in Approximately 12 Months
PDK1 Inhibitor Program Licensed from Millennium;
Development Candidate Selection to Take Place in 2014
Sunesis to Host Conference Call, Provide 2014 Outlook, Today at 11AM Eastern Time
SOUTH SAN FRANCISCO, CA, USA I January 9, 2014 I Sunesis Pharmaceuticals, Inc. (SNSS) today announced that it has expanded its hematology franchise through separate global licensing agreements for two preclinical kinase inhibitor programs. The company will host a conference call to discuss these agreements, as well as an outlook for 2014, today at 11:00 a.m. Eastern Time.
The first agreement, with Biogen Idec (BIIB), is for global commercial rights to SNS-062, a potent and selective non-covalently binding oral inhibitor of BTK (Bruton’s tyrosine kinase). BTK is a mediator of B-cell receptor signaling integral to the pathogenesis of B-cell malignancies. With characteristics and activity distinct from in-class compounds, SNS-062 may hold potential as a differentiated treatment for B-cell malignancies and other blood cancers. Sunesis anticipates filing an investigational new drug (IND) application for SNS-062 with the Food and Drug Administration in approximately one year to begin human clinical trials.
The second agreement, with Millennium: The Takeda Oncology Company, is for global commercial rights to several potential first-in class, pre-clinical inhibitors of the novel target PDK1 (phosphoinositide-dependent kinase-1). PDK1 is a key kinase and mediator of PI3K/AKT signaling, a pathway involved in cell growth, proliferation, differentiation, motility and survival. PDK1 inhibitors are expected to have unique effects on survival and invasion signaling and to be broadly active in both hematologic and solid tumor malignancies. Sunesis anticipates selecting a lead PDK1 development candidate this year to take into IND enabling studies.
Both BTK and PDK1 programs were originally developed under a research collaboration agreement between Biogen Idec and Sunesis. The PDK1 program was subsequently purchased by and exclusively licensed to Millennium in 2011 along with the more advanced program, MLN2480, a pan-RAF inhibitor currently in the maximum tolerated dose cohort expansion stage of a Millennium Phase 1, multicenter dose escalation study. SNS-062 and the PDK1 inhibitor will be developed exclusively by Sunesis. Sunesis anticipates only modest incremental expense associated with advancing both programs in 2014.
“These programs represent an exciting expansion of Sunesis’ pipeline which, with vosaroxin, provide the opportunity to create a leading hematology franchise,” said Daniel Swisher, Chief Executive Officer of Sunesis. “This pipeline is supplemented by other promising programs that continue their development through our collaborator-funded programs with Biogen Idec and Millennium. Taken together with vosaroxin, our wholly owned late-stage program, these efforts are expected to yield a number of important corporate milestones in the upcoming quarters, including a second quarter readout of the pivotal, Phase 3 VALOR trial of vosaroxin in first relapsed or refractory acute myeloid leukemia.”
Mr. Swisher added: “We look forward to a transformative 2014, which will include data from investigator sponsored trials of vosaroxin that were initiated in 2013, and, with a positive outcome to VALOR, the transition from a development- to a commercial-stage company.”
“As key mediators of signaling pathways known to drive a variety of hematologic and solid tumor malignancies, BTK and PDK1 are both compelling targets in the field of oncology,” said Adam R. Craig, M.D., Ph.D., Executive Vice President, Development and Chief Medical Officer of Sunesis. “Both programs have unique and differentiating features: the PDK1 program may yield a first-in-class compound, while SNS-062, as a distinct, non-covalently binding molecule, may prove clinically effective in settings where other agents, such as in ibrutinib and/or idelalisib, have failed. We look forward to the opportunity to develop these compounds in a variety of oncology indications.”
Conference Call Information
Sunesis will host an update conference call today, January 9 at 11:00 a.m. Eastern Time. The call can be accessed by dialing 877-546-5020 (U.S. and Canada) or 857-244-7552 (international), and entering passcode 47533862. To access the live audio webcast, or the subsequent archived recording, visit the “Investors and Media – Calendar of Events” section of the Sunesis website at www.sunesis.com. The webcast will be recorded and available for replay on the Sunesis website for two weeks.
About VALOR
VALOR is a Phase 3, randomized, double-blind, placebo-controlled, pivotal trial in patients with first relapsed or refractory AML. The trial is being conducted at more than 100 leading sites in the U.S., Canada, Europe, Australia, New Zealand and South Korea. Patients are randomized in a ratio of 1:1 to receive either vosaroxin on days one and four in combination with cytarabine daily for five days, or placebo in combination with cytarabine. The trial’s primary endpoint is overall survival. For more information on the VALOR trial, please visit www.valortrial.com.
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. Both the U.S. Food and Drug Administration (FDA) and European Commission have granted orphan drug designation to vosaroxin for the treatment of acute myeloid leukemia (AML). Additionally, vosaroxin has been granted fast track designation by the FDA for the potential treatment of relapsed or refractory AML in combination with cytarabine.
About Sunesis Pharmaceuticals
Sunesis is a biopharmaceutical company focused on the development and commercialization of new oncology therapeutics for the treatment of solid and hematologic cancers. Sunesis has built a highly experienced cancer drug development organization committed to advancing its lead product candidate, vosaroxin, in multiple indications to improve the lives of people with cancer.
