The Company reported progress on several product-related areas including: 1) Successful culmination of a three year research program funded by the National Institute of Infectious Disease of Japan indicating that a nasally delivered flu vaccine, when coupled with Ampligen®, yielded positive results in providing a more robust and longer lasting immune response in non-human primates; 2) In connection with Max Neeman International, a leading clinical research organization in India, the Company obtained approval to begin a Phase II b study from the Indian Drugs Controller General as it works to enroll subjects for the current monsoon season to treat seriously ill hospitalized flu patients evaluating Alferon N Injection®; 3) As a result of the Company's efforts to proceed with Phase II clinical testing of Alferon® LDO (an experimental biologic) for the potential prophylactic treatment of seasonal and / or pandemic influenza, three months of additional product stability data are being compiled and analyzed for submission to the U.S. Food and Drug Administration ("FDA"); and 4) New data on retrovirus presence in Chronic Fatigue Syndrome ("CFS") has been submitted (abstract) for potential presentation at a National Institutes of Health, U.S, workshop in September, 2010 and are being evaluated in connection with a contemplated Phase III confirmatory trial in CFS with Ampligen®, an experimental therapeutic.

In support of these clinical initiatives, the Company's wholly-owned New Brunswick, N.J. manufacturing facility continues to undergo plant renovations coupled with expansion in its overall production capacity.  FDA inspections in June, 2010, conducted in accordance with FDA procedures for Therapeutic Biological Products Inspections, provided routine Good Manufacturing Practice ("GMP") coverage and focused on the Company's approved Alferon N Injection® product. No deficiencies were found during the inspections and, accordingly, no FDA-483 Inspectional Observations were issued.

Overall, these clinical, research, and manufacturing programs reflect the breadth of the Company's on-going commitment to develop and further commercialize its various products.
