Juno Therapeutics Announces Complete Response and Corresponding Early Survival Data for JCAR014 in Patients with Ibrutinib-Refractory CLLJuno Therapeutics, Inc. (NASDAQ: JUNO), a biopharmaceutical company developing innovative cellular immunotherapies for the treatment of cancer, today announced in a presentation at the 58th American Society of Hematology (ASH) Annual Meeting encouraging early data for JCAR014 in patients with chronic lymphocytic leukemia (CLL) who failed treatment with ibrutinib. Insights from studies of the translational product, JCAR014, are being applied to the development of JCAR017 for the treatment of B-cell malignancies. Both JCAR014 and JCAR017 use a 4-1BB co-stimulatory domain and defined 1:1 cell ratio of CD4:CD8 T cells. "The responses and durability we've seen in this study are notable and demonstrate the potential for further investigation of JCAR017 for patients with relapsed/refractory high-risk CLL," said Mark J. Gilbert, M.D., Juno's Chief Medical Officer. "This is especially important, given recent data that show these patients, who progress early on ibrutinib, have poor clinical outcomes with a median survival of approximately three months. In addition, emerging response criteria, such as undetectable disease in the bone marrow at the molecular level by deep sequencing, appear to correlate with long-term response duration." The Phase I study (ASH Abstract #56), conducted by Cameron Turtle, MBBS, Ph.D., of the Fred Hutchinson Cancer Research Center, evaluated 24 heavily pre-treated patients, all of whom had failed ibrutinib, the standard-of-care treatment for CLL. Patients had received a median of five previous therapies, including three who failed prior allogeneic stem cell transplants. Patients received lymphodepletion with either fludarabine/cyclophosphamide (flu/cy) (N=21) or non-flu/cy (N=3) prior to infusion of JCAR014. Key data for the flu/cy cohort include:

ABOUT JUNO Juno Therapeutics is building a fully integrated biopharmaceutical company focused on re-engaging the body's immune system to revolutionize the treatment of cancer. Founded on the vision that the use of human cells as therapeutic entities will drive one of the next important phases in medicine, Juno is developing cell-based cancer immunotherapies based on chimeric antigen receptor and high-affinity T cell receptor technologies to genetically engineer T cells to recognize and kill cancer. Juno is developing multiple cell-based product candidates to treat a variety of B-cell malignancies as well as solid tumors. Several product candidates have shown compelling clinical responses in clinical trials in refractory leukemia and lymphoma conducted to date. Juno's long-term aim is to leverage its cell-based platform to develop new product candidates that address a broader range of cancers and human diseases. Juno brings together innovative technologies from some of the world's leading research institutions, including the Fred Hutchinson Cancer Research Center, Memorial Sloan Kettering Cancer Center, Seattle Children's Research Institute, the University of California, San Francisco, and The National Cancer Institute. Juno Therapeutics has an exclusive license to the St. Jude Children's Research Hospital patented technology for CD19-directed product candidates that use 4-1BB, which was developed by Dario Campana, Chihaya Imai, and St. Jude Children's Research Hospital. ABOUT THE JUNO-CELGENE COLLABORATION Celgene Corporation and Juno Therapeutics formed a collaboration in June 2015 under which the two companies will leverage T cell therapeutic strategies to develop treatments for patients with cancer and autoimmune diseases with an initial focus on chimeric antigen receptor (CAR) and T cell receptor (TCR) technologies. In April 2016, Celgene exercised its option to develop and commercialize the Juno CD19 program outside North America and China.
