Inventiva announces the presentation of a scientific abstract at the 83rd Scientific Sessions of the American Diabetes Association

Daix (France), Long Island City (New York, United States), June 24, 2023 – Inventiva (Euronext Paris and Nasdaq: IVA), a clinical-stage biopharmaceutical company focused on the development of oral small molecule therapies for the treatment of non-alcoholic steatohepatitis (NASH) and other diseases with significant unmet medical needs, today announced that the abstract “Lanifibranor Improves Markers of Cardiometabolic Health in Patients with NASH and Type 2 Diabetes, Correlated With Responses in Adiponectin Levels” has been selected for poster presentation during the American Diabetes Association’s 83^rd Scientific Sessions taking place on June 23-26, 202 in San Diego, United States.

Adiponectin plays a critical role in energy homeostatis by regulating insulin sensitivity, lipid metabolism and control of glycemia. In addition adiponectin has anti-inflammatory and anti-fibrotic effects in the liver. Low levels of adiponectin are associated with several metabolic conditions including T2D and NASH, and with an increased risk for cardiovascular disease. PPAR signaling is involved in disease pathways common to NASH and T2D, and this abstract evaluates the effect of lanifibranor, a pan-PPAR agonist, on adiponectin levels and improvement of markers of cardiometabolic health in patients with T2D and NASH.

Inventiva’s ‘NATIVE’ Phase IIb clinical trial, which evaluated lanifibranor in patients with non-cirrhotic NASH, has demonstrated beneficial effects on liver histology, NASH resolution and fibrosis regression. The authors of the abstract show that lanifibranor significantly increases the levels of adiponectin and that this increase is correlated with the improvements of cardiometabolic markers, including insulin resistance, glycemic control, lipid metabolism, and systemic inflammation, in patients with NASH and T2D or prediabetes.

The details of the presentation are as follows:

About lanifibranor

Lanifibranor, Inventiva’s lead product candidate, is an orally-available small molecule that acts to induce anti-fibrotic, anti-inflammatory and beneficial vascular and metabolic changes in the body by activating all three peroxisome proliferator-activated receptor (PPAR) isoforms, which are well-characterized nuclear receptor proteins that regulate gene expression. Lanifibranor is a PPAR agonist that is designed to target all three PPAR isoforms in a moderately potent manner, with a well-balanced activation of PPARα and PPARδ, and a partial activation of PPARγ. While there are other PPAR agonists that target only one or two PPAR isoforms for activation, lanifibranor is the only pan-PPAR agonist in clinical development for the treatment of NASH. Inventiva believes that lanifibranor’s moderate and balanced pan-PPAR binding profile contributes to the favorable tolerability profile that has been observed in clinical trials and pre-clinical studies to date. The FDA has granted Breakthrough Therapy and Fast Track designation to lanifibranor for the treatment of NASH.

About Inventiva

Inventiva is a clinical-stage biopharmaceutical company focused on the research and development of oral small molecule therapies for the treatment of patients with NASH, mucopolysaccharidoses (“MPS”) and other diseases with significant unmet medical need. The Company benefits from a strong expertise and experience in the domain of compounds targeting nuclear receptors, transcription factors and epigenetic modulation. Inventiva is currently advancing one clinical candidate, has a pipeline of two preclinical programs and continues to explore other development opportunities to add to its pipeline.

Inventiva’s lead product candidate, lanifibranor, is currently in a pivotal Phase III clinical trial, NATiV3, for the treatment of adult patients with NASH, a common and progressive chronic liver disease for which there are currently no approved therapies.

Inventiva’s pipeline also includes odiparcil, a drug candidate for the treatment of adult MPS VI patients. As part of Inventiva’s decision to focus clinical efforts on the development of lanifibranor, it suspended its clinical efforts relating to odiparcil and is reviewing available options with respect to its potential further development. Inventiva is also in the process of selecting an oncology development candidate for its Hippo signaling pathway program.

The Company has a scientific team of approximately 90 people with deep expertise in the fields of biology, medicinal and computational chemistry, pharmacokinetics and pharmacology, and clinical development. It owns an extensive library of approximately 240,000 pharmacologically relevant molecules, approximately 60% of which are proprietary, as well as a wholly-owned research and development facility.

Inventiva is a public company listed on compartment B of the regulated market of Euronext Paris (ticker: IVA, ISIN: FR0013233012) and on the Nasdaq Global Market in the United States (ticker: IVA). www.inventivapharma.com
