Inventiva announces a late breaker abstract and two additional abstracts on its lead compound, lanifibranor, at the AASLD The Liver Meeting® 2023

• The phase II study led by Dr. Kenneth Cusi evaluating lanifibranor in patients with T2D and MASLD was selected as late breaker.
• Two additional scientific abstracts from the NATIVE Phase IIb clinical trial evaluating lanifibranor for the treatment of patients with NASH have been selected  for presentation. The two abstracts show:
  • the correlation between the increase of adiponectin under lanifibranor and the improvement of histological and serum markers of NASH severity both in terms of activity and fibrosis.
  • the improvement of liver histology and markers of cardiometabolic health in patients with NASH treated with lanifibranor, independent of PNPLA3 genotype.

Daix (France), Long Island City (New York, United States), November 6, 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 nonalcoholic steatohepatitis (NASH) and other diseases with significant unmet medical needs, today announced that the phase II trial led by Dr. Cusi in patients with type two diabetes (T2D) has been accepted as late breaker, at the upcoming The Liver Meeting® 2023 hosted by the American Association for the Study of Liver Diseases on November 10-14, 2023 in Boston. In addition two other scientific abstracts have been selected for poster presentation.

The late breaker abstract “Lanifibranor reverses insulin resistance and improves glucose and lipid metabolism in patients with type 2 diabetes (T2D) and metabolic dysfunction-associated steatotic liver disease (MASLD)” presents results from a study sponsored by Dr. Cusi at the University of Florida, that evaluates the effect of lanifibranor on insulin resistance in the liver, muscle and adipose tissue, as well as its effect on intrahepatic triglyceride (IHTG) content in patients with T2D and Metabolic dysfunction associated steatotic liver disease (MASLD)¹.

The second abstract evaluates the correlation between adiponectin response with lanifibranor and the improvement of histological and serum markers of NASH severity, both in terms of disease activity and fibrosis. The change in adiponectin levels at end of treatment (categorized as unchanged, moderate or high increase) correlated positively to histological endpoints of NASH resolution and no worsening of fibrosis, improvement of fibrosis and no worsening of NASH, and NASH resolution and fibrosis improvement. The degree of adiponectin level increase correlated also with improvement of the NASH-CRN and SAF-Activity scores as well as with improvement of the individual components: steatosis, inflammation and ballooning. Lanifibranor-associated adiponectin increase also correlated with the improvement in histological fibrosis stage, pro-C3 levels and MACK-3 score. These data further support that adiponectin is a biomarker for the efficacy of lanifibranor treatment across the disease spectrum of NASH, from cardiometabolic health – as previously shown – to hepatic health. As a reminder, a 3.82 and 4.50 fold increase in adiponectin level were respectively reported in the 800mg arm and 1200mg arm during Inventiva’s NATIVE Phase IIb clinical trial.

The third abstract evaluates the impact of the PNPLA3 variant I148M, which is strongly associated with risk for and the progression of NASH, on the histological and cardiometabolic response to lanifibranor. In a retrospective analysis of Inventiva’s NATIVE Phase IIb clinical trial evaluating lanifibranor for the treatment of patients with NASH, histological and circulating marker responses were evaluated by PNPLA3 genotype subgroup. The response to lanifibranor treatment on the histological endpoints was similar across the three PNPLA3 genotype (II/IM/MM) despite a higher activity score measured at baseline in patients with MM genotype.
In addition, the improvement of cardiometabolic health markers (glycemic control, insulin, HOMA-IR, HsCRP, CAP and adiponectin) following treatment with lanifibranor was similar in the three PNPLA3 genotypes. These results demonstrate that the efficacy of lanifibranor on both liver histology and markers of cardiometabolic health appears to be independent of PNPLA3 status.

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 (also known as metabolic dysfunction-associated steatohepatitis (MASH)), 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
