SEATTLE--(EON: Enhanced Online News)--Juno Therapeutics, Inc. (NASDAQ: JUNO), a biopharmaceutical company developing innovative cellular immunotherapies for the treatment of cancer, today announced that it has defeated an attempt to invalidate a patent exclusively licensed by Juno that covers, among other things, a chimeric antigen receptor (CAR) T cell used for the treatment of B-cell malignancies, and that it is suing Kite Pharma, Inc., seeking a declaratory judgment that Kite’s lead product candidate, KTE-C19, will infringe the patent when commercially produced.
“Our efforts to amicably and reasonably resolve the dispute Kite initiated have been thwarted and today we are taking the next step towards fully resolving matters. Importantly, our filing will not prevent continued patient access while the legal dispute continues.”
In August 2015, Kite Pharma, Inc. filed an inter partes review in the U.S. Patent & Trademark Office in an attempt to invalidate U.S. Patent No. 7,446,190 by challenging all of its claims. Juno exclusively licenses the ’190 patent, titled “Nucleic Acids Encoding Chimeric T Cell Receptors,” from Sloan Kettering Institute for Cancer Research, an affiliate of Memorial Sloan Kettering Cancer Center. The patent covers, among other things, a construct for a CD-19 targeted CAR T cell treatment that employs a CD28 costimulatory domain.
The U.S. Patent & Trademark Office instituted a review of the patent and on December 16, 2016 issued a final written decision upholding all the claims of the patent.
“We are obviously pleased by the USPTO’s decision to uphold the patent,” said Bernard J. “Barney” Cassidy, General Counsel of Juno Therapeutics. “Our efforts to amicably and reasonably resolve the dispute Kite initiated have been thwarted and today we are taking the next step towards fully resolving matters. Importantly, our filing will not prevent continued patient access while the legal dispute continues.”
The lawsuit is being filed in the U.S. District Court for the District of Delaware. Juno and the Sloan Kettering Institute are represented by Irell & Manella LLP in both the IPR and the litigation.
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.
