Stellar Biotechnologies to Supply KLH to National Institutes of Health

LOS ANGELES, Sept. 5, 2018 /PRNewswire/ -- Stellar Biotechnologies, Inc. (Nasdaq: SBOT), a leading manufacturer of a key protein utilized in multiple immunotherapy development pipelines targeting Alzheimer's, autoimmune disease and cancers, among other diseases, announced today that it has been contracted by the U.S. National Institutes of Health (NIH) to supply the company's Stellar KLH protein for government-sponsored clinical studies.

The company reported that it has initiated product manufacturing for the NIH's National Cancer Institute, which plans to use a vialed formulation of Stellar KLH in dendritic cell-based cancer therapies. These experimental therapies, now in Phase 1 and Phase 2 clinical studies, utilize cells from a patient's own immune system to mount a response against tumors. To produce the vaccine, mononuclear cells are extracted from a patient, primed with tumor antigens and KLH and matured into dendritic cells before being administered back to the patient. According to scientists at the NCI Vaccine Branch's clinical research program, the use of KLH-loaded dendritic cells enhances the immune response and improves the efficacy of these personalized anti-tumor vaccinations.

Frank R. Oakes, Stellar Chief Executive Officer and President, said that the NIH has been a longtime supporter of aquaculture-produced KLH, due in part to the greater control and reliability of domesticated sources. "The adjuvant and immune-stimulating properties of KLH are well established and we are excited to see our products being utilized in this promising area of cancer research," said Mr. Oakes. "The critical role of KLH in dendritic cell vaccines demonstrates just how versatile this unique protein can be. This contract opens a new potential growth opportunity for KLH outside the KLH-conjugate vaccines clinical studies that we are currently supporting."

The National Institutes of Health, which operates as the nation's leading biomedical research agency, includes 27 research institutes and centers and is a component of the U.S. Department of Health and Human Services. The mission of NCI Vaccine Branch's clinical research program is to develop vaccines and immune-based therapies that harness the immune response to control, eradicate or prevent cancer and HIV infection.
