Eurofins Viracor, Inc. Responds to Patent Infringement Lawsuit By CareDx

September 26, 2019

Eurofins Viracor, Inc. (“Viracor”) became aware today that CareDx has filed suit in the United States District Court for District of Delaware, alleging infringement of U.S. Patent No. 8,703,652 by three of Viracor’s tests: Viracor TRAC™ Kidney dd-cfDNA, Viracor TRAC™ Heart dd-cfDNA and Viracor TRAC™ Lung dd-cfDNA.

“Based upon our review of the suit, we believe our tests do not infringe the ‘652 patent. Moreover, we believe CareDx’s ‘652 patent to be invalid. As such, Viracor intends to vigorously defend against this lawsuit, and we do not anticipate this suit to impact our commercialization efforts. We exclusively licensed the intellectual property to perform these tests from the same institution from which CareDx licensed its intellectual property. We note that CareDx seems to be attempting to limit other laboratories from offering different cell-free DNA testing methodologies to help physicians confirm active organ rejection for transplant patients. This is evidenced by CareDx’s similar lawsuit against Natera, Inc. earlier this year, which also included the ‘652 patent and which Natera is defending in similar fashion,” said David Morgan, Senior Vice President, Eurofins U.S. Clinical Diagnostics.

“Given the increasing number of diagnostic tools in the clinical marketplace related to organ rejection, it is important to note this lawsuit does not involve the TruGraf ® Blood Gene Expression Test, which will be offered by Viracor’s sister company Transplant Genomics, Inc. (“TGI”) upon receipt of a final Local Coverage Determination from Centers for Medicare & Medicaid Services via Palmetto GBA’s Molecular Diagnostic Services (MolDX) Program. While cell-free DNA tests provide important information to physicians seeking to rule out active rejection in kidney transplant patients already showing signs of renal dysfunction, TruGraf ® will be the first and so far only blood test that allows physicians to reassure patients with stable renal function that their graft is not harboring silent rejection without the need for an invasive and costly surveillance biopsy. Silent rejection occurs in about 30% of kidney transplant patients and if untreated can progress to active rejection,” added Morgan.

Through Viracor, TGI and Eurofins VRL, Inc., Eurofins U.S. Clinical Diagnostics offers an expansive suite of testing services covering pre-transplant through post-transplant patient monitoring. We provide the country’s most comprehensive portfolio of transplant diagnostic tests.
