Protection Results Against Malaria, Herpes and Cancer Reported With

April 25, 2002
VIENNA, Va., April 25 /PRNewswire-FirstCall/ -- CEL-SCI CORPORATION (Amex: CVM) and The Naval Medical Research Center (NMRC) announced today that a newly discovered peptide provided 100% protection against malaria infection in a mouse model. Dr. Yupin Charoenvit of NMRC presented these data at the Experimental Biology 2002 meeting in New Orleans, LA. This same peptide, called derG, has also induced protective effects in two other totally different and unrelated animal challenge models for herpes simplex virus and cancer. The peptide appears to increase the animal's ability to fight off all of these three diseases. The peptide is a modified version of a human sequence known to bind to both human and mouse immune cells and as such, the results obtained are thought to have direct applicability in man.

In the malaria study conducted by the Navy researchers, 100% protection from infection was observed after administration, two weeks apart, of only two doses as low as 5 micrograms per dose. Protection was defined as a total lack of malaria parasites in the blood of the animals at several time points after challenge, a very stringent test.

Data was also presented on studies of derG done in a mouse Herpes Simplex Virus skin scarification model by the team of Dr. Kenneth S. Rosenthal at NEOUCOM. The best results in reducing mortality and delaying the appearance of herpes lesions were seen when derG was administered one day before challenge.

Another set of data was presented on work done with derG by Onyvax, Ltd., a British biotechnology company. When used in the allogeneic melanoma (skin cancer) tumor vaccine model, derG improved protection conferred by an experimental tumor cell vaccine alone.

It is of great importance that the first two test systems did not involve the administration of disease antigen (e.g. malaria or herpes virus) with derG. This is unexpected because any vaccination typically requires both the use of an antigen (a piece of the disease) along with an adjuvant (an irritant designed to attract the immune system to the injection site where it will react to the disease antigen) administered at the same time. Yet, derG given alone, well ahead of the animals seeing any disease antigens, conferred protection against challenge by the disease causing organisms. This suggests that derG is acting early and directly on the immune system to enhance the ability to respond and protect itself from the disease causing organisms.

Geert Kersten, Chief Executive Officer of CEL-SCI said, "The fact that we were able to see protection without disease antigen in several diseases opens up the possibility that derG could become an inexpensive general immune regulatory drug that protects people from a large number of diseases. We would expect derG to also be useful in the treatment of diseases. We are looking for partners to develop the many potential applications for this remarkable product."

Potential indications for derG are: 1) Infectious diseases -- with antibiotic resistance on the rise, there is a great need for new treatments, particularly in hospital settings. derG could also potentially replace or augment current therapies for Influenza, Hepatitis B and Hepatitis C; 2) Sepsis; 3) Cancers; 4) Allergies -- derG could be a more effective replacement for allergy shots and other current therapies and/or augment their efficacy by changing the immune response normally induced by allergens. An oral form could reduce the need for or replace present oral therapies requiring daily or more frequent administration; 5) Some autoimmune conditions, such as autoimmune myocarditis; and 6) Vaccine adjuvant -- derG has the potential to enhance and to reduce the time to obtain protective immunity after vaccination. Its use may also eliminate or reduce the need for booster shots.

Several patent applications have been filed covering the composition of derG and related compounds, as well as methods and conditions for its use. CEL-SCI is looking for a partner for the development of derG and its analogues as potential treatments for the indications cited above. It also intends to pursue funding from government sources.

CEL-SCI Corporation is developing new immune system based treatments for cancer and infectious diseases. Its lead product, Multikine(TM), is in Phase II clinical studies against head & neck cancer and Phase I clinical studies for HIV-infected women with cervical dysplasia. The Company has operations in Vienna, Virginia and Baltimore, Maryland.
