Kite Pharma Announces Presentations Highlighting Cancer Immunotherapy T Cell Manufacturing Process

SANTA MONICA, Calif., Jan. 19, 2015 (GLOBE NEWSWIRE) -- Kite Pharma, Inc., (Nasdaq:KITE), a clinical-stage biopharmaceutical company focused on developing engineered autologous T cell therapy (eACT™) products for the treatment of cancer, today announced presentations on the Company's rapid, six-day manufacturing process for the production of Kite's lead product candidate, KTE-C19. The manufacturing technology enables a patient's T cells to be genetically modified using a gammaretroviral vector to express a chimeric antigen receptor (CAR) designed to target the antigen CD19, a protein expressed on the cell surface of B cell lymphomas and leukemias. Kite recently announced filing with the FDA an investigational new drug (IND) application to conduct a Phase 1/2 clinical trial of KTE-C19 for the treatment of patients with refractory aggressive non-Hodgkin lymphoma (NHL).

Presentations taking place at this week's Scale-Up and Manufacturing of Cell-Based Therapies IV, an Engineering Conferences International conference, being held in San Diego, California, include:

Oral Presentation: "Production of autologous T cells for multi-center trials"

Presenter: Marc Better, Ph.D., Vice President, Product Sciences, Kite Pharma

Summary: To prepare for Kite-sponsored multicenter trials, Kite, in conjunction with the National Cancer Institute Surgery Branch, has developed a rapid and efficient proprietary process for the generation of anti-CD19 CAR T cells.  Because refractory B cell malignancies can progress quickly, it is important to reduce the time between patient sample collection by apheresis and administration of the engineered T cells. In addition to a rapid, six-day timeframe, elements of the KTE-C19 manufacturing process include: efficient T cell stimulation and growth without anti-CD3/anti-CD28 beads; a robust closed system production, amenable to cGMP operations; rapid cell growth in serum-free cell culture medium; and cryo-preserved product that is transportable to multiple clinical sites. Further processing optimization was achieved while maintaining key parameters (including cell subset composition and T cell expansion).

Date and Time: Monday, January 19, 2015, 12:10 - 12:30PM Pacific Time

Poster Presentation: "Scale-up and Recovery of a Gammaretroviral Vector"

Authors: Timothy Langer, Marc Better, Yeuh-Wei Shen, Xiao-Chi Jia, all of Kite Pharma

Summary: Gammaretroviral vectors can be produced in large quantities and with high titers for ex vivo gene delivery in adoptive cell therapies. Using a process implemented at the National Cancer Institute as a basis, Kite is scaling up production of a retroviral vector to support multicenter clinical trials of an engineered T cell product. Kite's team implemented new process engineering, replacing previous filtration techniques with bioprocessing filters and allowing for streamlined manufacturing operations suitable to cGMP production.

Date and Time: Monday, January 19, 2015, 8:30 - 10:00PM Pacific Time
