-- Two late-breaking abstracts covering new data from Inventivas NATIVE Phase IIb clinical trial evaluating lanifibranor for the treatment of NASH have been selected for poster presentations during the congress -- These abstracts focus on the efficacy of lanifibranor in type-2 diabetic (TD2M) patients and its positive effect on key plasma biomarkers -- Presence during the congress will be highlightedwith an oral plenary presentation and include a total of four presentations/abstracts

Daix (France), November 2, 2020 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), mucopolysaccharidoses (MPS) and other diseases with significant unmet medical need, today announced that two late-breaking abstracts have been selected for poster presentations during the upcoming The Liver Meeting Digital Experience 2020, organized by the American Association for the Study of Liver Diseases (AASLD) on November 13-16, 2020.

The two late-breaking abstracts cover new data from the Companys NATIVE Phase IIb clinical trial evaluating lanifibranor for the treatment of NASH, focusing on the efficacy of lanifibranor in type-2 diabetic (TD2M) patients and its positive effect on key plasma biomarkers.

A third abstract covering the screening methodology used for patient selection during the NATIVE Phase IIb clinical trial has also been accepted for a poster presentation.

These three abstracts complement Inventivas presence at the AASLD The Liver Meeting Digital Experience 2020, where Inventiva had already been selected for an oral plenary presentation of the NATIVE Phase IIb clinical trial results, including new data on F2/F3 patients.

The details of the various presentations are as follows:

About lanifibranor

Lanifibranor, Inventivas 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 proliferatoractivated receptor (PPAR) isoforms, which are wellcharacterized 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 wellbalanced activation of PPAR and PPAR, and a partial activation of PPAR. While there are other PPAR agonists that target only one or two PPAR isoforms for activation, lanifibranor is the only panPPAR agonist in clinical development. Inventiva believes that lanifibranors moderate and balanced panPPAR binding profile contributes to the favorable tolerability profile that has been observed in clinical trials and preclinical studies to date.

About the NATIVE Phase IIb trial

The NATIVE (NAsh Trial to Validate IVA337 Efficacy) clinical trial was a 24-week randomized, double-blind, placebo-controlled Phase IIb clinical trial evaluating lanifibranor for the treatment of patients with NASH. The main purpose of the trial was to assess the efficacy of lanifibranor in improving liver inflammation and ballooning, the two histological markers included in the definition of the regulatory endpoint of NASH resolution. To be considered for inclusion, patients were required to have: a diagnosis of NASH confirmed by liver biopsy; a cumulative score of inflammation and ballooning (as measured using the SAF scoring system) of three or four out of four, indicating the presence of moderate to severe inflammation and ballooning; a steatosis score greater than or equal to one, indicating the presence of moderate to severe steatosis; and a fibrosis score less than four, indicating the absence of cirrhosis. The primary endpoint of the trial was a reduction in the combined inflammation and ballooning score of two points compared to baseline, with no worsening fibrosis, as measured by the SAF score. Secondary endpoints included NASH resolution, improvements in each of the steatosis, inflammation, ballooning and fibrosis scores from baseline as measured using the SAF score, improvements in various other fibrosis measures, improvements in several metabolic markers, improvements in steatosis, inflammation and ballooning as measured using the NAS score (NAFLD activity score), and safety.

The trial randomized 247 patients with NASH in 71 sites in Australia, Canada, Europe, Mauritius and the United States.About Inventiva

Inventiva is a clinical-stage biopharmaceutical company focused on the development of oral small molecule therapies for the treatment of NASH, MPS and other diseases with significant unmet medical need.

Leveraging its expertise and experience in the domain of compounds targeting nuclear receptors, transcription factors and epigenetic modulation, Inventiva is currently advancing two clinical candidates, as well as a deep pipeline of earlier stage programs.

Lanifibranor, its lead product candidate, is being developed for the treatment of patients with NASH, a common and progressive chronic liver disease for which there are currently no approved therapies. Inventiva recently announced positive topline data from its Phase IIb clinical trial evaluating lanifibranor for the treatment of patients with NASH.

Inventiva is also developing odiparcil, a second clinical-stage asset, for the treatment of patients with subtypes of MPS, a group of rare genetic disorders. At the end of 2019, Inventiva published positive results from its Phase IIa clinical trial evaluating odiparcil for the treatment of MPS VI adult patients.

In parallel, Inventiva is in the process of selecting an oncology development candidate for its Hippo signalling pathway program. Furthermore, the Company has established a strategic collaboration with AbbVie in the area of autoimmune diseases. AbbVie has started the clinical development of ABBV157, a drug candidate for the treatment of moderate to severe psoriasis resulting from its collaboration with Inventiva. This collaboration enables Inventiva to receive milestone payments upon the achievement of pre-clinical, clinical, regulatory and commercial milestones, in addition to royalties on any approved products resulting from the collaboration.

The Company has a scientific team of approximately 70 people with deep expertise in the fields of biology, medicinal and computational chemistry, pharmacokinetics and pharmacology, as well as in clinical development. It also owns an extensive library of approximately 240,000 pharmacologically relevant molecules, approximately 60% of which are proprietary, as well as a whollyowned research and development facility.

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