ADVR Further Expands Its Patent Portfolio; The Company is Awarded Its Seventeenth Patent.

YONKERS, N.Y. -- Advanced Viral Research Corp. (OTC Bulletin Board: ADVR) announced today that the patent office in China has granted the Company patent #ZL 00811493.5 entitled "Preparation of a Therapeutic Composition" for AVR118. The patent describes the composition of AVR118 and methods of manufacturing it.

"Developing a strong worldwide intellectual property estate is critical in the field of biotechnology," said Dr. Elma S. Hawkins, President and CEO of Advanced Viral Research Corp. "This is our second patent granted in China for AVR118, thereby providing additional protection for our flagship product."

Currently, ADVR is engaged in a Phase II, multi-center, randomized, double-blind United States study designed to evaluate the effect of a 4.0 ml dose of AVR118 administered to patients with systemic symptoms related to advanced cancers who are not candidates for, or who do not wish to receive, chemotherapy.

ADVR's AVR118 represents a biopolymer that possesses novel immunomodulatory activity. This peptide-nucleic acid complex, which to date has demonstrated a very favorable safety profile, appears to stimulate the proinflammatory responses required to combat viral infections such as AIDS and human papillomavirus, and to dampen aberrant autoimmune-type inflammatory responses, such as those which occur in patients with rheumatoid arthritis.

The Phase I/II clinical trial of AVR118 in AIDS patients, which was conducted in Israel, concluded that AVR118 continues to demonstrate evidence of unique patient benefits, a favorable safety profile, and no apparent drug-related adverse events. Unique patient benefits included weight gain, mood improvement, decrease in fatigue, and increase in ability to perform everyday tasks.
