InNexus Biotechnology Completes Preclinical Study Confirming in Vivo Effectiveness and Safety of Lead Candidate DXL625, Schedules Meeting With FDA

InNexus Biotechnology Inc., (OTC Bulletin Board: IXSBF; TSX VENTURE: IXS; http://www.ixsbio.com), a drug development company commercializing the next generation of monoclonal antibodies based on its Dynamic Cross Linking (DXL(TM)) technology, announces the completion of a large scale primate study confirming effectiveness and safety of its lead candidate DXL625 (CD20). The Company also announced that it has scheduled a meeting with the United States Food and Drug Administration (FDA) during the first half of 2009 to discuss the design of a clinical study.

"This study confirms that DXL625 is specific to the CD20 antigen present on NHL tumor cells and is a major milestone in our plan for clinical and commercial success," said Jeff Morhet, CEO and Chairman of InNexus. "This success paves the way for the filing of an IND and commencement of clinical trials of DXL625 in the near future." Complete results from this study are being compiled and will be presented at the annual scientific meeting of the American Association for Cancer Research (AACR) this spring.

InNexus' recently completed study was designed to confirm DXL625's in vivo safety and efficacy. The candidate was effective in completely eliminating all lymphocytes with a CD20 marker within hours at the lowest dose tested. No adverse events were seen even at a dose 100-fold higher than the lowest dose. The CD20 marker is the same as that found on tumors cells in patients with Non-Hodgkins Lymphoma patients. Previous studies have shown that DXL625 has greater potency as compared to existing therapeutic antibodies.

Pre-clinical data show that DXL625 has a safety profile equal to Rituxan(R) when evaluated in the same validated model. The preclinical study was conducted with a single injection, which confirms the remarkable potency of DXL625. In addition, the study showed no difference in immunogenicity as compared to Rituxan(R). Prior assessment of potential cross-reactivity using a limited panel of human tissue slices has revealed no off-target reactions.
