Daix (France), New York City (New York, United States), July 9, 2025 - Inventiva (Euronext Paris and Nasdaq: IVA) ("Inventiva" or the "Company"), a clinical-stage biopharmaceutical company focused on the development of oral therapies for the treatment of metabolic dysfunction-associated steatohepatitis ("MASH"), today announced a leadership transition with the appointment of Jason Campagna, MD, PhD, as President of Research and Development ("R&D") and Chief Medical Officer ("CMO") and Martine Zimmermann, PharmD, as Executive Vice President ("EVP") of Regulatory Affairs and Quality Assurance.

Dr. Campagna is joining Inventiva's executive leadership team and brings extensive expertise in the MASH field. He succeeds Pierre Broqua, PhD, co-founder and Chief Scientific Officer, who is transitioning to a consulting role as Scientific Advisor, and Michael Cooreman, MD, departing as CMO of the Company. Dr. Campagna most recently was the CMO at Q32 Bio and prior to that was the MASH Global Program Lead and CMO at Intercept Pharmaceuticals.

Dr. Zimmermann is also joining the Company's executive leadership team. She was most recently Senior Vice President, Head of Regulatory Affairs at Ipsen where she successfully led a team that secured regulatory approvals of two liver disease drugs, including Iqirvo®, a dual PPARa/d agonist, for the treatment of primary biliary cholangitis. Prior to Ipsen, Dr. Zimmermann was Senior Vice President and Head of Global Regulatory Affairs & Quality at Alexion Pharma (also known as AstraZeneca Rare Disease).

Frederic Cren, CEO of Inventiva stated: "Jason and Martine both bring exceptional leadership and experience during this pivotal time for the Company as we plan for the readout of our NATiV3 Phase 3 study next year and lanifibranor's potential regulatory approval and commercialization. Having played an integral part in the creation and building of Inventiva, Pierre will continue to actively support the team in a scientific consulting role. I would also like to express my gratitude to Michael for his scientific leadership and contributions in advancing lanifibranor to this stage and we wish him every success in his future endeavors."

Jason Campagna, MD, PhD, President, R&D and CMO of Inventiva commented: "Inventiva has built a robust scientific and clinical foundation, and I'm thrilled to join the team at this pivotal moment as we advance lanifibranor toward anticipated regulatory submissions. Having led the design and execution of one of the field's most advanced clinical programs at Intercept-including the first-ever NDA submission in this indication-I've seen firsthand both the scientific complexity and the urgency of bringing effective therapies to patients with MASH. I believe the promising results of the Phase 2b NATIVE trial reflect the thoughtful design of lanifibranor development program-and that's deeply exciting to me. With lanifibranor well on its way in the Phase 3 NATiV3 registrational trial, I look forward to working closely with the exceptional team at Inventiva to deliver on the promise of bringing a novel treatment to patients with MASH."

Martine Zimmermann, PharmD, Executive Vice President of Regulatory Affairs and Quality Assurance of Inventiva said:"I'm excited to take on this leadership role at a time when Inventiva is entering a critical regulatory phase for lanifibranor, a first-in-class pan-PPAR agonist for the treatment of MASH. In my career, I've been closely involved in leading global regulatory strategy and approval of compounds for the treatment of chronic liver diseases, including a PPAR, in a number of geographies, including the US, Europe and Japan. I am now eager to apply that experience to support lanifibranor toward a potential approval."
