SOUTH SAN FRANCISCO, Calif., June 23, 2016 (GLOBE NEWSWIRE) -- Atara Biotherapeutics, Inc. (Nasdaq:ATRA), a biopharmaceutical company focused on developing meaningful therapies for patients with severe and life-threatening diseases, today announced that the EMA has classified the Company’s EBV-CTL product candidate as an Advanced Therapy Medicinal Product (ATMP) that falls within the definition of a somatic cell therapy medicinal product. Atara’s EBV-CTLs are under development for the treatment of patients with EBV Post-Transplant Lymphoproliferative Disorder (EBV-PTLD).
Therapies classified as ATMP have the potential to reshape the treatment of a wide range of conditions, particularly in disease areas where conventional approaches are inadequate. ATMP classification was established to regulate cell and gene therapy and tissue engineered medicinal products, support development of these products and provide a benchmark for the level of quality compliance for pharmaceutical practices. ATMP classification can provide developers with scientific regulatory guidance, help clarify the applicable regulatory framework and development path, provide access to all relevant services and incentives offered by the EMA and can also be advantageous when submitting clinical trial dossiers to national EU regulatory authorities.
“We are pleased to receive EMA’s classification of our EBV-CTL product candidate as an ATMP in the European Union. ATMP classification, together with the recent orphan drug designation granted by both the US FDA and EMA, underscores the compelling need for new treatments for PTLD following hematopoietic cell transplant (HCT) and solid organ transplant (SOT),” said Isaac Ciechanover, M.D., President and Chief Executive Officer of Atara Bio. "We are committed to expanding our T-cell platform globally, and we are looking forward to commencing our pivotal trials in EBV-PTLD following HCT and SOT later this year.”
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 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 EBV-CTL utilizes a technology in which T-cells are collected from the blood of third-party donors and then exposed to EBV antigens. 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. In the context of EBV-PTLD, Atara’s EBV-CTL finds the cancer cells expressing EBV and kills them. EBV-CTL is currently being studied in ongoing Phase 2 clinical trials in patients with EBV-associated cancers, including PTLD and nasopharyngeal carcinoma.
