Daix (France), Long Island City (New York, United States) / Paris (France) and Waltham (United States), June 8, 2023 – Inventiva (Euronext Paris and Nasdaq: IVA) (the “Company”), a clinical-stage biopharmaceutical company focused on the development of oral small molecule therapies for the treatment of patients with non-alcoholic steatohepatitis (“NASH”) and other diseases with significant unmet medical needs and Echosens, a high-technology company providing a comprehensive range of diagnostic solutions for liver health, today announce their collaboration in raising awareness about NASH and increase access to screening for patients at risk of developing NASH.

NASH is a chronic and progressive metabolic liver disease that, if left undiagnosed and unmanaged, can lead to cirrhosis or liver cancer and may result in the need for a liver transplant. Although NASH is often described as “silent”, patients with NASH do have an impaired quality of life¹ and an increased risk of cardiovascular and liver-related complications².

With a global prevalence ranging from 1.5% to 6.45%³ and expected to increase 63% by 20303, there is an urgent need to diagnose patients at higher risk of progression. This is why Inventiva and Echosens are joining forces to provide easier access to screening using FibroScan® in local communities. This awareness and screening program will take place in about ten communities at risk for NASH in the United States and Europe, and will be supported by expert hepatologists and local patient and community organizations.

Frédéric Cren, Chairman, CEO and cofounder of Inventiva, stated: “On this 6^th annual edition of International NASH Day, we are extremely proud to join forces with Echosens in this effort to increase both NASH awareness and identification of patients at risk of developing NASH. A tremendous effort is still required to ensure that patients are not left undiagnosed and that they eventually receive the care that they need. We are delighted to combine our expertise in the development of potential therapies for NASH together with Echosens’ world-class know-how in NASH diagnosis, for this initiative that will shed further light on this disease and help screen and identify patients at risk of developing NASH.”

“There is a pressing need for a broader adoption of non-invasive liver tests to increase the diagnosis rate and improve the care of people living with NASH. We, alongside with our partners, have a joint responsibility to shape a future where patients have access to easy diagnosis solutions and effective therapies” said Dominique Legros, CEO of Echosens. “We are very proud to partner with Inventiva to launch initiatives facilitating screening of NASH and increasing awareness of this disease among patients, healthcare providers and other stakeholders.”

About NASH

Non-alcoholic steatohepatitis (NASH) is the most severe form of non-alcoholic fatty liver disease (NAFLD). It is a progressive metabolic liver disease characterised by fat accumulation and inflammation in the liver, which can lead to scarring, or fibrosis, and eventually end-stage liver disease and death. The risk of progression to advanced liver disease, including liver cancer, is higher in people with NASH than in the general population, and NASH is already the leading cause of waitlist registration and liver transplant in women in the United States⁴. Moreover, NASH increases the risk of developing cardiovascular diseases⁵. Known risk factors for NASH include dyslipidaemia, type 2 diabetes, obesity, metabolic syndrome and hypertension. There are currently no approved treatments for NASH globally, and people with NASH are left with very few management options.

About Echosens

Pioneer in its field, Echosens significantly changed the practice of liver assessment with FibroScan®, the non-invasive solution for comprehensive management of liver health. For the past decade, FibroScan® has been recognized worldwide and validated by over 3,500 peer-reviewed publications and 160 international guidelines. Echosens has made FibroScan® available in over 100+ countries enabling millions of liver examinations worldwide.

At Echosens we envision a future where…
… liver health is at the core of total health,
… every medical professional has the necessary tools to measure the health of the liver, identify pathologies, and manage treatments simply, accurately and effectively,
… every patient has the right to receive information about their liver health in a simple, timely,
and easy-to-understand manner.

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 signalling 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).
