Daix (France), September 8, 2021 – 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 the initiation of its NATiV3 Phase III clinical trial evaluating lanifibranor for the treatment of NASH.1 The first clinical trial sites have been activated in the United States and first patients have been screened. In addition, more than 330 sites across 25 countries have already been qualified2 of which more than a third in the United States.

NATiV3 (NASH lanifibranor Phase 3 trial) is a randomized, double-blind, placebo-controlled, Phase III clinical trial evaluating 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 clinical trial includes two parts: a 72-week treatment of approximately 900 patients to assess the effect of lanifibranor on the primary composite endpoint of NASH resolution and fibrosis improvement of at least one stage and on the key secondary endpoints of NASH resolution with no worsening of fibrosis, and improvement of fibrosis with no worsening of NASH (part 1). Following part 1, the trial will remain blinded and continue in approximately 2,000 patients to evaluate the effect of lanifibranor on delaying NASH disease progression, measured by a composite endpoint that includes progression to cirrhosis, liver-related clinical outcome events, and all-cause death, as compared to the placebo control arm (part 2).  

The primary composite endpoint of part 1 of the NATiV3 Phase III clinical trial is identical to the composite efficacy endpoint used in Inventiva’s NATIVE Phase IIb clinical trial which was met by both lanifibranor doses with statistical significance, including in NASH patients with F2/F3 fibrosis and NASH patients with type 2 diabetes (T2DM).

The last visit of the last patient enrolled in part 1 of the NATiV3 Phase III clinical trial is planned for the first half of 2024, with the publication of the topline results of part 1 of the trial expected for the second half of 2024.

If part 1 of the NATiV3 trial is successful, Inventiva intends to seek accelerated approval in the United States and conditional approval in the EU for lanifibranor. The study will also provide a comprehensive safety data set to evaluate, in combination with the therapeutic efficacy data, the benefit/risk ratio of lanifibranor therapy as the basis for full regulatory approval in both the United States and the EU following completion of part 2 of the trial.

Prof. Sven Francque, M.D., Ph.D., Antwerp University Hospital and co-principal investigator of the NATiV3 Phase III clinical trial, said: “The start of the pivotal Phase III clinical trial with lanifibranor represents a key milestone in its development, as well as for the patient community and the NASH field more generally. During the NATIVE Phase IIb trial, 21% and 31% of patients in the lanifibranor 800mg/day and 1200mg/day dose groups respectively achieved the Phase III primary composite endpoint after only 24 weeks of treatment compared to 7% in the placebo arm. These results give us great confidence in the NATiV3 trial and the potential of lanifibranor.”

Prof. Arun Sanyal, M.D., Virginia Commonwealth University and co-principal investigator of the NATiV3 Phase
III clinical trial, added: “As an orally-available small molecule and the only pan-PPAR agonist currently in clinical development for the treatment of NASH, lanifibranor has shown a unique and very promising mechanism of action thus far. Based on its favorable safety profile and efficacy results observed in the previous Phase IIb trial, we are very excited about the potential benefits lanifibranor could bring to patients.”

Dr. Michael Cooreman, Chief Medical Officer of Inventiva, commented:We are pleased to announce the start of our highly-anticipated NATiV3 Phase III clinical trial in NASH. While NASH patients continue to suffer from this devastating disease without any approved treatment available today, our entire team is fully committed to addressing this critical, unmet medical need. We have decided to replicate several key elements of the previous Phase IIb trial, including using the same patient enrollment screening criteria, and have developed a central biopsy review process in alignment with regulatory authorities. We believe in the therapeutic potential of lanifibranor, which should put us in a strong position to seek accelerated approval in the US and conditional marketing authorization in the EU.”

The initiation of the NATiV3 trial follows the publication of positive results from Inventiva’s NATIVE Phase IIb clinical trial with lanifibranor in NASH in June 2020 as well as its designation as Breakthrough Therapy by the U.S. Food and Drug Administration (FDA) in October 2020.

About the NATiV3 Phase III trial

The two-part NATiV3 (NASH lanifibranor Phase 3 trial) clinical trial is a randomized, double-blind, placebo-controlled trial, evaluating the long-term efficacy and safety of lanifibranor in adult patients with non-cirrhotic NASH and F2/F3 stage of liver fibrosis.

Patients will be randomized 1:1:1 in placebo and treatment arms (800mg/daily or 1200mg/daily of lanifibranor) and stratified based on their fibrotic stage (F2 and F3) as well as presence or absence of type 2 diabetes (T2DM).

Part 1 of the trial will assess the effect of lanifibranor (800mg/daily and 1200mg/daily) compared to placebo on the primary composite endpoint of NASH resolution and improvement of fibrosis of at least one stage. The key secondary enpoints include NASH resolution without worsening of fibrosis as well as improvement of fibrosis and no worsening of NASH. Part 1 is expected to recruit approximately 900 patients selected upon liver biopsy and enrolled in approximately 300 sites, with the objective to obtain accelerated approval from the Food and Drug Administration (FDA) in the United States and conditional approval from the European Medicines Agency (EMA) in the EU for lanifibranor based on a pre-specified histology analysis after 72 weeks of treatment. The last visit of the last patient for part 1 is scheduled for the first half of 2024 and the publication of topline results for the second half of 2024.

Part 2 will follow the 72-week histology analysis and will assess the effect of lanifibranor (800mg/daily and 1200mg/daily) compared to placebo on delaying NASH disease progression measured by a composite endpoint that includes progression to cirrhosis, liver-related clinical outcome events, and all-cause death. In part 2, the trial will remain blinded and continue in a total of approximately 2,000 patients until the occurrence of a pre-specified number of liver-related clinical events. The trial would be completed on a post-marketing basis in the event that accelerated (U.S.) / conditional (EU) approval is received. Based on the results from part 2, Inventiva plans to seek full regulatory approval for lanifibranor in both the United States and the EU.

In addition to the key primary and secondary endpoints, the impact of lanifibranor on biomarkers of metabolic health will be evaluated as part of the trial. The occurrence of Major Adverse Cardiovascular Events (MACE), such as myocardial infarction and stroke, will also be evaluated as an exploratory efficacy endpoint and to establish the safety profile of lanifibranor.

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. 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 NASH

Non-alcoholic steatohepatitis (NASH) is a serious liver disease characterized by excessive fat accumulation in the liver, chronic inflammation and tissue injury (hepatitis), resulting in progressive fibrosis that can lead to cirrhosis, and subsequently portal hypertension, liver insufficiency and potential liver cancer. The prevalence of NASH is rapidly increasing globally in parallel to the growing epidemics of obesity and type 2 diabetes (T2DM); correspondingly, the proportion and number of liver transplants attributable to NASH has expanded considerably in the past years. To date, there are still no drug therapies approved for the treatment of NASH.

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 and obtained Breakthrough Therapy and Fast Track designation for lanifibranor in the treatment of 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. Inventiva announced positive topline data from its Phase IIa clinical trial evaluating odiparcil for the treatment of adult MPS VI patients at the end of 2019 and received FDA Fast Track designation in MPS VI for odiparcil in October 2020.

In parallel, Inventiva is in the process of selecting an oncology development candidate for its Hippo signalling pathway program.
