BioStrategies, 2007. ANX-201 resensitizes NRTI-resistant virus. Novel mechanism of action is reflected in unique resistance profile. NRTIs Protease inhibitors NNRTIs HIV treated population in the US: Resistance to one or more drugs is estimated at 76%. Estimated drug resistance by class (HIV-treated): Resistance to >1 class: 47% Resistance to 3 classes: 13% percent of virus resistant to drug class

ZANAFLU Preclinical Efficacy Zanaflu (ANX-211) has demonstrated efficacy against viruses responsible for the common cold, influenza and other respiratory tract infections in preclinical studies No antiviral added (positive control) Zinc only preparation ANX-211 HEK cells infected by adenovirus carrying ?-gal gene. Virus-infected cells are blue from X-gal staining. ANX-211 was more effective than the zinc only preparation in protecting the cells against the adenovirus infection. virus-infected cells stained blue
