BERKELEY, CA--(Marketwire - Apr 20, 2011) - Dynavax Technologies Corporation (
Dynavax's Phase 1 study will assess the safety of DV1179, an inhibitor of TLR7 and TLR9, in multiple ascending doses. A total of 24 healthy subjects, divided into three dose groups, will each receive four weekly injections of DV1179. Data from this study is expected later this year. Following successful completion of the trial, Dynavax expects to initiate a proof-of-mechanism study in lupus patients.
Peer-Reviewed Publications Document Program's Potential
In December, 2010, Dynavax reported in the JOURNAL OF EXPERIMENTAL MEDICINE (JEM, Volume 207, Number 13) data that suggested an important role of the key innate immune receptors TLR7 and TLR9 in a novel mouse model of skin conditions similar to cutaneous lupus. The company's inhibitor of TLR7 and TLR9 prevented and reversed disease suggesting therapeutic application of the inhibitor for the treatment of cutaneous lupus and related skin conditions.
In the June 16, 2010 issue of NATURE, data demonstrated in both human blood cells and animal models of lupus that glucocorticoid resistance characteristic of lupus could be mediated through TLR7 and TLR9 and could be reversed by Dynavax's TLR7/TLR9 inhibitor. Glucocorticoids are commonly used for the treatment of many autoimmune and inflammatory conditions, but the high doses required for effective treatment of lupus lead to significant side-effects and restrict the utility of these drugs.
About Dynavax's TLR Inhibitors
Dynavax's TLR inhibitors are a novel class of oligonucleotides, called immunoregulatory sequences (IRS), that specifically inhibit the TLR-induced inflammatory response associated with autoimmune and inflammatory diseases. Preclinical data from animal model studies show Dynavax's TLR inhibitors block induction of IFN-alpha and also reduce symptoms in animal models of multiple autoimmune diseases, such as lupus, inflammatory skin disorders, and rheumatoid arthritis. The National Institutes of Health in Bethesda, MD and the Alliance for Lupus Research contributed funding for Dynavax's preclinical work.
