• Inventiva has lifted the voluntary pause on screening and randomization in the NATiV3 clinical trial following the approval from the US central IRB of the amended protocol and ICF.
• Screening of patients is resuming in sites operating under central IRB in the US.
• Other sites and countries are expected to resume screening and randomization activities progressively over the next weeks.
• Last Patient First Visit is currently targeted for first half 2024.

Daix (France), Long Island City (New York, United States), March 7, 2024 – 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 non-alcoholic steatohepatitis (NASH) and other diseases with significant unmet medical needs, today announced that it has lifted the previously disclosed¹ voluntary pause on screening and randomization of its NATiV3 clinical trial and that sites are resuming screening activities.

Following the Suspected Unexpected Serious Adverse Reaction (“SUSAR”) in a patient enrolled in the study, Inventiva chose to voluntarily pause screening and randomization of new patients in the NATiV3 trial to implement the recommendations of the independent Data Monitoring Committee (“DMC”), which included liver monitoring every 6 weeks for each patient enrolled in the trial, and amending the protocol to exclude newly screened patients diagnosed or with a predisposition to autoimmune liver and thyroid disease. In addition, the Company has made amendments to the Informed Consent Form (“ICF”) in line with the DMC recommendations. During the pause, the DMC has continued to receive updates on the patient status and has reviewed and approved the amendments made to Inventiva’s study documents.

Inventiva received the first approval from the central IRB overseeing clinical research in the United States.  Clinical sites located in the United States operating under central IRB have meanwhile resumed screening and randomization activities. This is an important milestone as 152 sites of the NATiV3 clinical trial sites are operating under central IRB and have so far randomized over 60% of the patients in the main cohort. Inventiva expects to progressively obtain the approvals required by local authorities to restart screening and randomization in other countries over the next few weeks.

Frédéric Cren, Chairman, Chief Executive Officer and cofounder of Inventiva, stated: “The well-being of our patients is paramount in our clinical research, and we are delighted to see that the patient who experienced the SUSAR is expected to make a full recovery. We want to thank all sites and all patients currently enrolled and in screening for their dedication to our study. Our team has worked diligently, and we are pleased to see screening and randomization resuming in our American sites under central IRB. Our sites operating under central IRB have contributed to more than 60% of all patients randomized in the trial and we expect them to be key in securing the last patients needed to finalize enrollment. Our ongoing interactions with the NATiV3 sites give us confidence in their strong commitment to resume the recruitment activities and we are looking forward to completing enrollment in the NATiV3 study with their support.”  

Prior to the voluntary pause, 913 patients were already randomized in the NATiV3 clinical trial including 731 in the main cohort and over 550 patients were in screening. Inventiva anticipates the last patient first visit for the NATiV3 clinical trial in the first half of 2024. 

About lanifibranor

Lanifibranor, Inventiva’s lead product candidate, is an orally-available small molecule that acts to induce antifibrotic, 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 the NATiV3 Phase III trial

NATiV3 is a randomized, double-blind, placebo-controlled clinical trial designed to evaluate the long-term efficacy and safety of lanifibranor (800mg/daily and 1200mg/daily) in adult patients with biopsy-proven non-cirrhotic NASH and F2/F3 stage of liver fibrosis. The trial takes place in 24 countries and in more than 400 clinical sites and to recruit approximately 900 patients to be treated over a 72-week period. The effect of lanifibranor will be assessed on several histological endpoints, including NASH resolution and improvement of fibrosis of at least one stage.

An exploratory cohort is anticipated to enrol approximately 200 patients with NASH and fibrosis screen-failed on histology for the main NATiV3 clinical trial. Inventiva anticipates that this exploratory cohort may allow the generation of additional data using non-invasive tests and contribute to the regulatory safety database requirement to support the planned submission for potential accelerated approval to the Food and Drug Administration (FDA) and potential conditional approval to the European Medicines Agency (EMA) of lanifibranor for the treatment of NASH.

Topline results of NATiV3 are expected for the half 2026. For more information about NATiV3, visit clinicaltrials.gov.

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 a 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
