Aegis' ProTek(R) Excipients Prevent Aggregation and Eliminate Unwanted beta-Interferon Immunogenicity

SAN DIEGO, CA--(Marketwire - September 1, 2010) -  Recombinant human beta-interferon reduces the frequency of multiple sclerosis (MS) exacerbations and improves MS outcome measures. Unfortunately, current beta-interferon drug products form aggregates that provoke a neutralizing antibody response in MS patients, significantly reducing the effectiveness of the drug.

In a Journal article titled: "n-Dodecyl-β-D-Maltoside Inhibits Aggregation of Human Interferon-β-1b and Reduces Its Immunogenicity" which appeared in the Journal of Neuroimmune Pharmacology, published online on June 7, 2010 scientists from a leading US University Medical School report that addition of a patented ProTek® excipient, a pharmaceutical grade of dodecyl maltoside developed by Aegis, inhibits aggregation and prevents development of antibodies in vivo suggesting a route to greatly improved beta interferon formulations. The abstract of the scientific report may be viewed online at:

According to Dr. Edward T. Maggio, CEO of Aegis Therapeutics, "Aggregation-induced immunogenicity is a problem for many protein therapeutics, reducing drug effectiveness and in extreme instances, causing life-threatening adverse reactions as with erythropoietin and Factor VIII. And because protein aggregation also adversely affects manufacturing process yields and drug potency it has become a major concern for pharmaceutical formulators worldwide."

ProTek® excipients are being used to prevent aggregation of monoclonal antibodies, human growth hormone, parathyroid hormone, and insulin, as well as a number of undisclosed proprietary peptide or protein therapeutics now in development.
