FDA Grants GENFIT’s GNS561 Orphan Drug Designation for the Treatment of Cholangiocarcinoma
Lille (France), Cambridge (Massachusetts, United States), September 13, 2022 – GENFIT (Nasdaq and Euronext: GNFT), a late-stage biopharmaceutical company dedicated to improving the lives of patients with severe chronic liver diseases, today announced that the U.S. Food and Drug Administration (FDA) has granted Orphan Drug Designation to GNS5611 (ezurpimtrostat), a novel clinical-stage autophagy/PPT1 inhibitor, for the treatment of cholangiocarcinoma.
Cholangiocarcinoma is a rare liver malignancy with high mortality and limited treatment options. It occurs mostly in people over the age of 50.
GNS561 (ezurpimtrostat) is a PPT-1 (Palmitoyl Protein Thioesterase-1) inhibitor that blocks autophagy. Autophagy is activated in tumor cells in response to certain conditions, due to a tumor cell growth in advanced cancers. GNS561 has completed pre-clinical studies and a Phase 1b trial confirming the rationale for targeting cholangiocarcinoma. A Phase 2 trial is expected to start in the fourth quarter 2022, with a first patient visit expected in the first quarter 2023.
Dr Mark Yarchoan, Associate Professor of Oncology at John Hopkins Medicine (Baltimore, MD) commented: “Cholangiocarcinoma is a rare cancer with a high mortality rate. Patients have limited treatment options, particularly following first line therapy. This is why new therapies are urgently needed and is one of the reasons that GNS561 was granted Orphan Drug Designation by the FDA. There is a real path forward for new options for second line treatment in cholangiocarcinoma, and GNS561 represents a strong second-line therapy candidate and hope to patients.”
GNS561 is a PPT-1 (Palmitoyl Protein Thioesterase-1) inhibitor that blocks autophagy. Autophagy is activated in tumor cells in response to certain conditions, due to a tumor cell growth in advanced cancers. One of the key cellular organs implicated in the autophagy process is the lysosome. By entering the lysosomes and binding to its target, GNS561 has an important inhibiting activity on late-stage autophagy, which leads to tumor cell death.
Cholangiocarcinoma is a type of cancer that forms in the slender tubes (bile ducts) that carry the digestive fluid bile. Cholangiocarcinoma occurs mostly in people over the age of 50. Cholangiocarcinoma is divided into intrahepatic and extrahepatic types based on where the disease occurs in the bile ducts. Cholangiocarcinoma is often diagnosed when it is advanced, making successful treatment difficult to achieve. Several risk factors of chronic inflammatory damage and increased cellular turnover have been established, such as primary sclerosing cholangitis (a cholestatic liver disease), liver flukes, biliary tract cysts, hepatolithiasis and toxins. Treatment options for cholangiocarcinoma are limited and associated with high rates of tumor recurrence, and short survival times.
GENFIT is a late-stage biopharmaceutical company dedicated to improving the lives of patients with severe chronic liver diseases characterized by high unmet medical needs. GENFIT is a pioneer in liver disease research and development with a rich history and strong scientific heritage spanning more than two decades. Thanks to its expertise in bringing early-stage assets with high potential to late development and pre-commercialization stages, today GENFIT boasts a growing and diversified pipeline of innovative therapeutic and diagnostic solutions.
Its R&D is focused on three franchises: cholestatic diseases, Acute on Chronic Liver Failure (ACLF) and NASH diagnostics. In its cholestatic diseases franchise, ELATIVE™, a Phase 3 global trial evaluating elafibranor1 in patients with Primary Biliary Cholangitis (PBC) is well underway following a successful Phase 2 clinical trial. Topline data is expected to be announced in the second quarter 2023. In 2021, GENFIT signed an exclusive licensing agreement with IPSEN to develop, manufacture and commercialize elafibranor in PBC and other indications. 2 GENFIT is also developing GNS5611 in cholangiocarcinoma following the acquisition of exclusive rights in this indication from Genoscience Pharma in 20213. In ACLF, a Phase 1 clinical program with nitazoxanide has been initiated with data expected as early as the third quarter 2022. As part of its diagnostic solutions franchise, the Company entered into an agreement with Labcorp in 2021 to commercialize NASHnext®, powered by GENFIT’s proprietary diagnostic technology NIS4® in identifying at-risk NASH.
GENFIT has facilities in Lille and Paris, France, and Cambridge, MA, USA. GENFIT is a publicly traded company listed on the Nasdaq Global Select Market and on compartment B of Euronext’s regulated market in Paris (Nasdaq and Euronext: GNFT). In 2021, IPSEN became one of GENFIT’s largest shareholders and holds 8% of the company’s share capital. www.genfit.com
