The Story

City of Hope was granted a $5,217,004 early translational research award by the California Institute for Regenerative Medicine (CIRM) to support the development of a T cell-based immunotherapy that re-directs a patient’s own immune response against glioma stem cells. City of Hope has been awarded more than $49.7 million in grant support from CIRM since awards were first announced in 2006.

City of Hope is a pioneer in T cell immunotherapy research, helping to develop genetically modified T cells as a treatment for cancer. This strategy, termed “adoptive T cell therapy,” focuses on redirecting a patient’s immune system to specifically target tumor cells, and has the potential to become a promising new approach for treatment of cancer.

“In this research, we are genetically engineering a central memory T cell that targets proteins expressed by glioma stem cells,” said Stephen J. Forman, M.D., Francis and Kathleen McNamara Distinguished Chair in Hematology and Hematopoietic Cell Transplantation and director of the T Cell Immunotherapy Research Laboratory. “Central memory T cells have the potential to establish a persistent, lifelong immunity to help prevent brain tumors from recurring.”

The American Cancer Society estimates that more than 22,000 people in the U.S. will be diagnosed with a brain tumor this year, and 13,700 will die from the disease. Glioma is a type of brain tumor that is often difficult to treat and is prone to recurrence. Currently, less than 20 percent of patients with malignant gliomas are living five years after their diagnosis. This poor prognosis is largely due to the persistence of tumor-initiating cancer stem cells, a population of malignant cells similar to normal stem cells in that they are able to reproduce themselves indefinitely. These glioma stem cells are highly resistant to chemotherapy and radiation treatments, making them capable of re-establishing new tumors.

Researchers at City of Hope previously have identified several proteins as potential prime targets for the development of cancer immunotherapies, such as interleukin 13 receptor alpha 2, a receptor found on the surface of glioma cells, and CD19, a protein that is active in lymphoma and leukemia cells. Both investigational therapies are currently in phase I clinical trials. Forman is the principal investigator for the newly granted study which will develop a T cell that targets different proteins expressed by glioma stem cells. Christine Brown, Ph.D., associate research professor, serves as co-principal investigator, and Michael Barish, Ph.D., chair of the Department of Neurosciences, and Behnam Badie, M.D., director of the Brain Tumor Program, serve as co-investigators on the project.

“Because cancer stem cells are heterogeneous, our proposed therapy will target multiple antigens to cast as wide a net as possible over this malignant stem cell population,” said Brown.

“While in this effort, we are targeting a neurological cancer, our approach will lead to future studies targeting other cancers, including those that metastasize to the brain,” added Barish.

“The CIRM grant will help us to build a targeted T cell therapy against glioma that can offer lasting protection, determine the best way to deliver the treatment, establish an efficient process to manufacture these T cells for treatment, and get approval for a human clinical trial,” said Badie.

City of Hope is also a collaborative partner — providing process development, stem cell-derived cell products and regulatory affairs support — in two other CIRM-funded projects that received early translational research grants. Larry Couture, Ph.D., senior vice president of City of Hope’s Sylvia R. & Isador A. Deutch Center for Applied Technology Development and director of the Center for Biomedicine & Genetics, is working with Stanford University and Children’s Hospital of Orange County Research Institute on their respective projects.

About the CIRM Early Translational Research III Awards

CIRM’s Early Translational Awards program supports projects that are in the initial stages of identifying drugs or cell types that could become disease therapies. These awards mark the third round of funding for the Early Translational Awards program, and marks the stem cell agency’s first ever collaboratively funded research projects with China, the federal government of Australia, and a new project with Germany.

“Our collaborative funding program brings together the best researchers around the world,” said Alan Trounson, Ph.D., CIRM president. “These partnerships are critical in engaging the best minds and enabling the elite scientists of the world to work together to drive research towards the clinic for patients. Our 25 collaborative projects with nine funding partners have so far leveraged more than $65 million in funding for stem cell research projects worldwide. The sun now never sets on the CIRM collaborative projects and scientists are stretching out to one another across the globe to achieve discoveries that will be game changing in medicine.”

About CIRM

CIRM was established in November 2004 with the passage of Proposition 71, the California Stem Cell Research and Cures Act. The statewide ballot measure, which provided $3 billion in funding for stem cell research at California universities and research institutions, was overwhelmingly approved by voters, and called for the establishment of an entity to make grants and provide loans for stem cell research, research facilities and other vital research opportunities. A list of grants and loans awarded to date may be seen here: http://www.cirm.ca.gov/for-researchers/researchfunding .

About City of Hope

City of Hope is a leading research, treatment and education center for cancer, diabetes and other life-threatening diseases. Designated as a comprehensive cancer center, the highest recognition bestowed by the National Cancer Institute, and a founding member of the National Comprehensive Cancer Network, City of Hope’s research and treatment protocols advance care throughout the nation. City of Hope is based in Duarte, Calif., just northeast of Los Angeles, with community practice sites in South Pasadena, Glendale, Santa Clarita, the Antelope Valley and Palm Springs. Its hospital is ranked as one of “America’s Best Hospitals” in cancer by U.S.News & World Report. Founded in 1913, City of Hope is a pioneer in the fields of bone marrow transplantation and genetics.
