Earlier this year, researchers at the University of Texas Southwestern Medical Center in Dallas, the Institute of Molecular Medicine at the University of Texas Health Science Center in Houston, and other collaborating institutions found that individuals with a mutated ANGPTL4 gene have significantly lower triglyceride levels and higher levels of HDL cholesterol (or "good" cholesterol).(1) These results from human genetic studies further support Lexicon's therapeutic strategy based on original observations made using animal models.
Lexicon scientists discovered ANGPTL4's utility as a potential
cardiovascular disease target as part of its Genome5000(TM)
program, and the discovery was selected for inclusion in its
collaboration with Genentech, Inc. The collaboration with Genentech
was initiated in December 2002 to discover the functions of
secreted proteins and potential antibody targets identified through
Genentech's Secreted Protein Discovery Initiative (also referred to
as the SPDI program), and was expanded in November 2005 to include
the advanced research, development and commercialization of new
biologic drugs. Under the collaboration, Lexicon has the right to
develop and commercialize biotherapeutic drugs for up to six
targets. Genentech retains an option on the potential development
and commercialization of the biotherapeutic drugs that Lexicon
develops from the collaboration under a cost and profit sharing
arrangement. ANGPTL4, referred to internally as LG842, is one of
two targets already chosen by Lexicon for internal development.
Lexicon has already generated versions of ANGPTL4 monoclonal
antibodies that are currently in preclinical evaluation to identify
