SOUTH SAN FRANCISCO, Calif., March 16, 2016 (GLOBE NEWSWIRE) -- Atara Biotherapeutics, Inc. (Nasdaq:ATRA), a biopharmaceutical company focused on developing meaningful therapies for patients with severe and life-threatening diseases that have been underserved by scientific innovation, today announced that its collaborating investigators at QIMR Berghofer Medical Research Institute will present data on autologous targeted EBV-CTLs in a Clinical Trials Minisymposium Session at the American Association for Cancer Research (AACR) 2016 Annual Meeting, which will be held in New Orleans, LA, April 16-20, 2016. The presentation will report clinical results on the use of EBV-CTLs to treat patients with EBV-associated nasopharyngeal carcinoma (NPC), which accounts for approximately 6,000 cases annually in the US and EU combined and approximately 80,000 cases worldwide.
“We are encouraged by these results. We believe these clinical findings in NPC may extend the reach of Atara Bio’s cellular therapy platform from hematologic malignancies to solid tumors,” said Isaac Ciechanover, M.D., President and Chief Executive Officer of Atara Bio.
In October 2015, Atara Bio and QIMR Berghofer entered into exclusive license and research agreements under which Atara Bio has exclusive, worldwide rights to develop and commercialize allogeneic, or "off-the-shelf", CTLs targeted to multiple epitopes of the Epstein-Barr virus utilizing technology developed by QIMR Berghofer. The QIMR Berghofer technology complements Atara Bio's ongoing CTL development efforts by selectively targeting specific epitopes and antigens of EBV that are associated with NPC and other diseases. Additional applications for which the technology may be appropriate include the treatment of gastric cancer, as well as certain autoimmune disorders such as multiple sclerosis. Atara Bio anticipates filing an IND for allogeneic targeted EBV-CTLs in 2017. In addition, Atara Bio has an option to license the autologous targeted EBV-CTL product candidate from QIMR Berghofer.
Details of the presentation are as follows:

About Targeted EBV-CTL
T-cells are a critical component of the body's immune system and can be harnessed to counteract viral infections and some cancers. By focusing the T-cells on specific proteins involved in cancers and infections, the power of the immune system can be employed to combat these diseases. Atara's targeted EBV-CTL utilizes a technology in which T-cells are collected from the blood of third-party donors and then activated to recognize specific epitopes of select EBV antigens implicated in certain solid tumors and autoimmune disorders such as NPC, gastric cancer, and multiple sclerosis. The resulting activated T-cells are then expanded, characterized, and stored for future therapeutic use in an appropriate partially human leukocyte antigen, or HLA, matched patient, providing an “off-the-shelf”, allogeneic, cellular therapeutic option for patients.
About Atara Biotherapeutics, Inc.
Atara Biotherapeutics, Inc. is a biopharmaceutical company focused on developing meaningful therapies for patients with severe and life-threatening diseases that have been underserved by scientific innovation, with an initial focus on immunotherapy and oncology. Atara Bio’s programs include T-cell product candidates and molecularly targeted product candidates. The T-cell product candidates include EBV-CTL, CMV-CTL and WT1-CTL and harness the power of the immune system to recognize and attack cancer cells and cells infected with certain viruses. The molecularly targeted product candidates include STM 434. These product candidates target activin and myostatin, members of the TGF-beta family of proteins, and have demonstrated the potential to have therapeutic benefit in a number of clinical indications.
