Leiden University Medical Center licenses novel diagnostic for Rheumatoid Arthritis to INOVA Diagnostics
LEIDEN, The Netherlands and SAN DIEGO, Jan. 29, 2013 /CNW/ - Leiden University Medical Center (LUMC) and INOVA Diagnostics are pleased to announce the completion of an exclusive, worldwide license agreement for technology developed at LUMC to detect antibodies to carbamylated proteins (anti-CarP). This technology represents an important advance in the diagnosis of Rheumatoid Arthritis (RA).
"The detection of autoantibodies in sera of RA patients has provided important insight into the processes that initiate and drive RA. Since anti-CarP antibodies can also be detected in a subgroup of patients for whom so far no serological markers were available we believe this may provide new insight into the pathogenesis of RA," said Dr. Leendert Trouw, Assistant Professor at LUMC.
"With new treatment options at hand it is now possible to apply early and aggressive treatment. Understanding which patients would benefit most from such an intervention is important to maximize efficiency, and detection of anti-CarP antibodies may identify such patients," said Prof. Tom Huizinga, head of the Department of Rheumatology at LUMC. Prof. Rene Toes, head of the Rheumatology Research Lab adds, "We are trying to understand the disease, RA, and unraveling how the presence of autoantibodies like anti-CarP contribute to RA will make it possible to design novel strategies that may prevent the onset of RA."
"We believe the anti-CarP technology represents a significant advance in the diagnosis of RA, helping to close the serological gap that exists with current biomarkers," said Roger Ingles, CEO of INOVA Diagnostics. 1 "The team at LUMC has an impressive track record in research and biomarker discovery in RA, including the design of the second generation CCP peptide. We are pleased to partner with this prestigious team to advance the research related to anti-CarP, and commercialize this important new biomarker."
A study published last year by the team at LUMC in Proceedings of the National Academy of Sciences showed that IgG and IgA antibodies recognizing carbamylated antigens were present in about 50% of RA patients. Anti-CarP antibodies recognize homocitrulline and are therefore distinct from anti-citrullinated protein antibodies (ACPA), including anti-Cyclic Citrullinated Peptide (anti-CCP), a biomarker commonly used to diagnose RA. Anti-CarP IgG and IgA were detected in 16% and 30% of ACPA negative RA patients respectively. Additionally, anti-CarP antibodies were shown to be predictive of a more severe course of disease as measured by radiological progression in ACPA negative RA patients.2,3
