InNexus Inc. Lead Candidate DXL625 Outperforms Rituxan in Additional Animal Studies


9/16/2008 11:44:18 AM

BRITISH COLUMBIA, Canada, Sept. 16 /PRNewswire-FirstCall/ -- InNexus Biotechnology Inc. , a drug development company commercializing the next generation of monoclonal antibodies based on its technology, Dynamic Cross Linking (DXL(TM)), announced today the results of an extensive mouse tumor study demonstrating superiority of InNexus' DXL625 (CD20) versus Rituxan(R) in the xenograft model.

InNexus plans to submit the data for publication along with additional data from animal studies recently completed and presented at the American Association for Cancer Research (AACR) 2008 Annual Conference. The company has also launched a large scale study of DXL625 with primates, designed to evaluate toxicity and pharmokinetics, enabling the company to move the product to the FDA toward human testing.

"A study performed by an independent group investigating the survival of mice intravenously injected with B-lymphoma cells and treated subsequently with DXL625 showed a significant improvement in outcome compared to animals treated with equivalent doses of Rituxan(R), a commercially available anti-CD20 antibody," said Dr. Thomas Kindt, InNexus' Chief Scientific Officer. "Animals treated with either drug had a superior outcome when compared to those receiving inactive control (vehicle), however DXL625 had a substantial advantage over the competing antibody. We are confident that these results will translate to therapeutic advantage when DXL625 is used in human subjects."

"The DXL(TM) technology platform builds better antibodies and soon you'll be able to see our strategy to expand the NHL marketplace. We enhance an antibody's potency in a real, measurable and predictable fashion," said Jeff Morhet, Chairman and Chief Executive Officer. "I'm pleased with our scientific progress, regulatory plans and soon we'll be well positioned to begin formal discussions with the FDA."

About DXL(TM) Technology Platform

DXL(TM) technology works by integrating self-binding peptides into monoclonal antibodies, potentiating target binding. Modified antibodies "cluster" upon engaging the target receptor site, resulting in greater "molecular mass" at the point of association. DXL(TM) antibodies have significantly extended dissociation rates, as measured by surface plasmon resonance. As a consequence, this may facilitate cancer cell destruction in a target dependent manner by increasing apoptosis, antibody dependent cell cytotoxicity and complement-dependent cytotoxicity.
