SAN DIEGO, CA January 12, 2009/MarketWire/-- Nerveda Inc. and Aegis Therapeutics
LLC today announced preclinical results from their joint collaboration aimed at
developing non-injectable formulations of the beta-interferons. The beta interferons,
beta-1a (tradename Rebif®), and beta 1b (tradenames Betaseron® and Betaferon®) are
closely related injectable protein drugs in the interferon family that are used to treat both the relapsing-remitting and secondary-progressive forms of multiple sclerosis (MS). The beta interferons are currently administered by subcutaneous injection and have been proven clinically to slow the advance of multiple sclerosis and reduce the frequency of attacks. Current worldwide combined annual sales of Rebif®, Betaseron® and Betaferon® are approximately $4 Billion.
Because proteins are large and fragile molecules, they cannot be administered orally
and are typically administered by injection. They are often subject to instability due to aggregation of the protein molecules – particularly upon storage and handling at nonrefrigerated temperatures. The resulting protein aggregates are more poorly absorbed
into the blood stream upon injection due to their increased size, and induce development of circulating antibodies to interferon in patients that reduce the effectiveness of the drug over time.
Leading medical scientists at Johns Hopkins University, expert in the treatment of
neurological diseases, in collaboration with Nerveda and Aegis have applied Aegis’
Intravail® transmucosal absorption enhancement, and ProTek® protein stabilization
technologies to address these problems and have demonstrated for the first time that the beta interferons can be administered intranasally to prevent nerve damage in preclinical animal models of multiple sclerosis. In addition, the new formulations were shown to reduce or eliminate the immunogenicity of Betaseron® and Rebif®, administered either by injection or intranasally, while substantially increasing stability in a stress test involving constant agitation at elevated temperatures for extended periods of time.
Dr. Edward Maggio, Ph.D., CEO of Aegis Therapeutics, who participated in the
research, said, “since interferons will continue to be the foundation of MS therapy, it is critical that non-invasive delivery options for patients be developed.” Maggio also indicated, “the reduction in immunogenicity and the increase in stability also address a significant unmet need of the currently available beta-interferon therapies.”
Nerveda plans to begin testing the new formulation in clinical trials in early 2009 in
collaboration with clinicians and scientists at John Hopkins University Medical Center
and other sites.

About Aegis Therapeutics
Aegis Therapeutics LLC is a drug delivery technology company commercializing its
patented or proprietary drug delivery and drug formulation technologies through productspecific licenses. Our patented Intravail® drug delivery technology enables the noninvasive delivery of a broad range of protein, peptide and non-peptide macromolecular therapeutics that can currently only be administered by injection. Aegis’ Intravail® absorption enhancement agents provide exceptionally high and unmatched bioavailability performance, comparable in efficiency to subcutaneous injection, via the intranasal administration route. Intravail® has also been successfully applied to buccal, oral, and rectal administration of small molecule, peptide, and nucleotide-analog type drugs. Our patented ProTek® technology allows creation of proprietary, easily manufacturable, and stable aqueous or lyophilized dosage forms that maintain the integrity and physiological activity of many protein and peptide therapeutics. ProTek® technology is applicable to injectable, intranasal, and other dosage forms of peptide or protein therapeutics.
