LOS ANGELES, June 21, 2018 /PRNewswire/ -- Stellar Biotechnologies, Inc. (Nasdaq: SBOT), a leading manufacturer of a key protein utilized in multiple immunotherapy development pipelines targeting Alzheimer's, lupus and cancer, among other diseases, today announced the successful completion of a research study focused on the molecular composition of the company's KLH products. The quality analysis was completed as part of Stellar's initiatives to support later stage clinical trials of drug candidates that utilize KLH as a carrier molecule and immunostimulant.

As part of the study, third party researchers analyzed the patterns of carbohydrates that attach to the KLH protein through a biologic process known as glycosylation. The compositional profile of these glycans, as they are known, are believed to enhance the immunogenicity of KLH. Due in part to the large size and complexity of this glycosylation, KLH has never been synthesized.

Stellar Executive Vice President of Corporate Development, Gregory T. Baxter, PhD reported that study results demonstrated highly consistent molecular structure from batch to batch, a key attribute for a biologically sourced protein.

"These results confirm that our production and manufacturing processes are able to reliably produce a consistent product. The data showed that glycan site occupancy and site-specific glycosylation were equivalent among the production lots tested, among other findings," said Dr. Baxter. He noted that the research study also provided greater insight into the characteristics of the KLH molecule that may be useful in better understanding conjugation efficiency, a metric important to therapeutic vaccine developers. Stellar is planning additional product development studies to support its customers and partners.

To produce Stellar KLH, hemocyanin protein is extracted from its native source using Stellar's patented process and then purified and manufactured into various grades and formulations. Due in part to its controlled aquaculture source and manufacturing methods, Stellar KLH has been shown to produce vigorous primary and secondary immune responses. Researchers interested in obtaining Stellar KLH, or obtaining technical specifications for research or GMP-grade KLH, may contact Stellar business development department at (805)488-2800 or
