MedImmune and Juno Therapeutics Announce Immuno-Oncology Clinical Trial Collaboration

On April 23, 2015 MedImmune and Juno reported that they have entered into a new collaboration to conduct combination clinical trials in immuno-oncology with one of Juno’s investigational CD19-directed chimeric antigen receptor (CAR) T cell candidates and MedImmune’s investigational programmed cell death ligand 1 (PD-L1) immune checkpoint inhibitor, MEDI4736 (Press release, Juno, APR 23, 2015, View Source [SID:1234503138]). Under the initial development plan, both companies will explore the safety, tolerability and preliminary efficacy of the combination therapy as a potential treatment for patients with non-Hodgkin lymphoma (NHL).

"We are pleased to enter into this clinical trial collaboration with Juno Therapeutics as our initial venture into the promising emerging field of CAR T cell therapies," said Dr. Ed Bradley, Senior Vice President and Head of the Oncology Innovative Medicines unit, MedImmune. "The combination of Juno’s CAR T cell candidate with MEDI4736 adds to our broad program of immuno-oncology combination trials, addressing multiple immune pathways and working with industry-leading partners to explore the significant potential of immunotherapies in transforming treatments for cancer."

Under the terms of the non-exclusive collaboration, MedImmune and Juno will jointly co-fund the initial Phase Ib study, which is expected to begin later in 2015. The companies will also explore the combination of MEDI4736 with a next-generation, Juno-developed fully human CD19-directed CAR T cell candidate.

"We believe combination strategies such as this will help us better understand the full potential of our engineered T cell platform in both hematological and solid tumor settings," said Mark W. Frohlich, M.D., Executive Vice President, Research & Development at Juno Therapeutics. "We look forward to working with MedImmune, a leader in immuno-oncology and checkpoint inhibition, in understanding the potential clinical benefit of combining these two potent therapeutic classes."

About MEDI4736
MEDI4736 is an investigational human monoclonal antibody directed against programmed cell death ligand 1 (PD-L1). Signals from PD-L1 help tumours avoid detection by the immune system. MEDI4736 blocks these signals, countering the tumour’s immune-evading tactics.
MEDI4736 was accelerated into Phase III clinical development in non-small cell lung cancer and head and neck cancer. The OCEANS clinical development programme will evaluate MEDI4736 as monotherapy and in combination with a CTLA-4 (tremelimumab) in lung cancer, across the spectrum of the disease. In head and neck cancer, MEDI4736 is being investigated both as monotherapy and in combination with tremelimumab, looking at patients with different PD-L1 expression status who have failed on chemotherapy.
About Chimeric Antigen Receptor (CAR) Technology
Juno’s chimeric antigen receptor (CAR) technology genetically engineers T cells to recognize and kill cancer cells. Juno’s CAR T cell technology inserts a gene for a particular CAR into the T cell, enabling it to recognize cancer cells based on the expression of a specific protein located on the cell surface. When the engineered T cell engages the target protein on the cancer cell, it initiates a cell-killing response against the cancer cell.
