► Biomarker signatures were developed to predict histological treatment response to lanifibranor treatment in patients with MASH and fibrosis

► The biomarker signatures developed for fibrosis improvement, MASH resolution and composite histological endpoints, suggested better predictive accuracy than other diagnostic scores available including FIB4, FIBC3, ABC3D, NFS, ELF and MACK-3

► The biomarker signatures suggested strong predictive accuracy, with AUROC values above 0.80 that may indicate high reliability in distinguishing responders from non-responders

► The analysis confirmed that histological response to lanifibranor could be assessed with non-invasive signatures based on blood markers

Daix (France), New York City (New York, United States), April 24, 2025 – 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 metabolic dysfunction-associated steatohepatitis (“MASH”) and other diseases with significant unmet medical needs, today announced publication in the peer-reviewed medical journal Clinical Gastroenterology and Hepatology, of its analysis on new non-invasive biomarker signatures predictive of histology response following treatment with lanifibranor in patients with MASH and fibrosis.

Pr. Jérôme Boursier, Head of Department Hepato-gastroenterology and digestive oncology at the University Hospital Centre of Angers, stated: "Our collaboration with Inventiva has been instrumental in addressing the critical need for reliable non-invasive biomarkers in MASH. With the effects of lanifibranor on histological endpoints observed in the NATIVE Phase 2b trial and our encouraging biomarker dataset, we are optimistic about developing robust composite biomarker scores which could predict treatment response and therefore the identification of patients most likely to respond to treatment with lanifibranor. In our analyses, the biomarker signatures were observed to outperform the current scores available in predicting the response to lanifibranor. We look forward to continuing our efforts to further refine these signatures and ultimately transforming patient management in chronic liver disease."

Pierre Broqua, Chief Scientific Officer and cofounder of Inventiva, commented: “Our collaboration with Professor Boursier and his team has enabled us to develop robust biomarker signatures that significantly enhance our ability to predict treatment response for patients treated with lanifibranor using a combination of serum-based biomarkers obtained in clinical practice. These signatures were developed and validated using NATIVE and we aim to further our analysis with the data from our Phase 3 clinical trial. The analysis further strengthens our confidence in the potential for lanifibranor to become a liver-targeted backbone treatment for MASH.”
                                                                        
The analysis assessed 71 biomarkers of interest (65 laboratory parameters and 6 diagnostic scores) measured in the Phase 2b NATIVE at baseline and after 24 weeks of treatment with lanifibranor 800mg and 1200mg/daily, in order to select biomarkers predictive of histological responses: MASH resolution with fibrosis improvement (E1), MASH resolution without fibrosis worsening (E2), and fibrosis improvement alone without worsening of MASH (E3).
