Juno Therapeutics to Highlight CAR T Advances in B-cell Malignancies at ASH 2016

-- Updated JCAR017 NHL data to be presented

-- Analyst and Investor Event and Webcast on Monday, December 5, at 8:30 p.m. Pacific Time

SEATTLE--()--Juno Therapeutics, Inc. (NASDAQ: JUNO), a biopharmaceutical company focused on re-engaging the body’s immune system to revolutionize the treatment of cancer, today announced that seven oral and four poster presentations detailing updated clinical and preclinical results generated in partnership with its collaborators will be presented at the 58th American Society of Hematology (ASH) Annual Meeting. Senior executives will also review results and provide an update on Juno’s clinical development program at an analyst and investor event, which will also be available via webcast.

“Presentations at ASH will showcase new data that support our best-in-class CAR T strategy across a range of B-cell malignancies,” said Mark J. Gilbert, M.D., Juno’s Chief Medical Officer. “The responses we are seeing with our product candidates, including updated JCAR017 results in adults with relapsed/refractory NHL, demonstrate the potential of our CAR T programs for patients in need of more treatment options. We are also learning more about cell characterization and toxicities, which are critical to improving the patient experience, our product candidates’ benefit-to-risk ratio, and potentially moving CAR T treatment into earlier lines of therapy.”

New data with JCAR017 in adult patients with relapsed/refractory diffuse large B-cell lymphoma (DLBCL), which is a subtype of NHL, and final data from the PLAT-02 trial for pediatric patients with relapsed/refractory acute lymphoblastic leukemia (ALL) will be presented. JCAR017 uses a defined CD4:CD8 cell composition and 4-1BB as the costimulatory domain, which differentiates it from other CD19-directed CAR T product candidates advancing to commercialization. In addition, final data from a Phase I trial with JCAR014 in high-risk, ibrutinib-refractory patients with chronic lymphocytic leukemia (CLL) will also be presented in an oral presentation.

The following will be presented at ASH:
