Nantes, France, June 17, 2011 - The biotech company TcLand Expression is pleased to announce the
financial support awarded by Oseo and the European Regional Development Fund (ERDF) for the
validation study of the first companion diagnostic test in rheumatoid arthritis. The program is mainly
dedicated to setting up a prospective European multicentre clinical trial to validate the diagnostic
performance of a molecular test to predict non-response to anti-TNF treatment (in particular
infliximab Remicade®) in Rheumatoid Arthritis patients.
This test will have a major impact on patients suffering from Rheumatoid Arthritis, a chronic disease
that affects one in a hundred people in western countries. Studies have shown that as much as 30%
of RA patients do not respond or respond adequately to TNF inhibitors, a burden for healthcare
systems that will reach several billion euros in the coming decade. The test could therefore become a
cornerstone to prevent therapeutic failure and allows clinicians to immediately select an alternative
treatment for their patients.
“We greatly acknowledge support and trust given by Oseo over the years, their grant together with
the ERDF grant will reinforce and accelerate the validation of our test, making it possible to include
large international cohorts”, says Marina Guillet, VP Head of Laboratory. The test was developed
using blood samples from cohorts of European, US and Japanese patients. The opportunity to
clinically validate the test on patients from different continents will allow TcLand Expression to target
One of the major public health concerns, rheumatoid arthritis is a chronic, progressive, debilitating auto-
immune disease that affects approximately 1% of the worldwide population. Despite the important
advancements concerning the treatment of Rheumatoid Arthritis during the past 10 years, many patients
remain partial responders and true remission is achieved by only a minority. A major goal in the field is thus to
predict response to treatment prior to starting a new therapy, in order to optimize patient care, reduce the risk
of adverse effects or joint destruction and to positively influence healthcare systems in terms of overall costs.
TcLand Expression is a recognized pioneer in the discovery, development and validation of gene expression
biomarkers for unmet medical needs in immunology. The company benefits from an exceptional scientific and
clinical environment. For more information, please visit our website: www.tcland-expression.com
