 FDA Approval of an Investigator Initiated IND Application to Conduct Phase II Study of Lanifibranor in Type 2 Diabetic Patients with Non-Alcoholic Fatty Liver Disease

• Study to enroll first patient in the third quarter 2018 with topline results expected early 2020
• FDA approval is a positive signal for SSc and NASH IND applications

Daix (France) June 20, 2018 - Inventiva S.A. ("Inventiva" or the "Company"), a biopharmaceutical company developing innovative therapies in nonalcoholic steatohepatitis (NASH), systemic sclerosis (SSc) and mucopolysaccharidosis (MPS), today announced that the U.S. Food and Drug Administration (FDA) has accepted the investigator initiated Investigational New Drug (IND) application providing clearance to proceed with the Phase II study of lanifibranor in type 2 diabetic patients with nonalcoholic fatty liver disease (NAFLD). This FDA approval is also a positive signal for the planned Company IND applications in SSc and NASH.

The trial to be conducted by Dr. Kenneth Cusi, Chief of the Division of Endocrinology, Diabetes & Metabolism in the Department of Medicine at the University of Florida, Gainesville, is expected to enroll 64 patients treated for a 24-week period with a single daily dose of lanifibranor (800 mg/day) or placebo and 10 subjects in a healthy, non-obese control group. The study's overall objective is to measure the metabolic improvements induced by lanifibranor, and its effect on steatosis in type 2 diabetic patients with NAFLD. Additionally, this study will detect lanifibranor's impact on fibrosis using the most recent imaging and biomarker technology. Its main endpoints are a decrease of liver steatosis assessed by state-of-the-art imaging, including H-MRS (Proton Magnetic Resonance Spectroscopy), a decrease of insulin resistance (glucose clamp, HBA1c), a decrease in de novo lipogenesis, and safety. The first patient is expected to be enrolled in the third quarter of 2018 and topline results are expected beginning of 2020.

"With its unique pan-PPAR profile, lanifibranor has shown very good safety features, relevant efficacy data in NASH preclinical models as well as positive metabolic effects in a Phase IIa study in diabetic patients," Dr. Cusi said. "We anticipate the results of this study to translate well to diabetic patients with NAFLD or NASH and look forward to demonstrating that lanifibranor could become a very valuable drug for these patients."
