  • Initiation of the clinical development program of lanifibranor in Japan with the dosing of the first participant in Phase 1 study

  • Positive results could support the initiation of a pivotal Phase 3 trial in patients in Japan with MASH

  • The study represents the first significant step of Inventiva’s and Hepalys’s partnership toward the development of lanifibranor in Japan and South Korea

Daix (France), New York City (New York, United States), Tokyo (Japan), February 20,  2025 – Inventiva (Euronext Paris and Nasdaq: IVA) (“Inventiva” or 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, and Hepalys Pharma, Inc. (“Hepalys”), a company incorporated in Japan and founded by Catalys Pacific, announced today the initiation of the clinical development program of lanifibranor in Japan with the first Japanese participant dosed in a Phase 1 clinical trial evaluating the safety, tolerability, pharmacokinetics (“PK”) and pharmacodynamics (“PD”) of lanifibranor.

As part of the single-center study, 32 subjects will be separated randomly into four cohorts and will receive lanifibranor once daily for 14 days.

The trial is conducted pursuant to the terms of the exclusive licensing agreement entered into in 2023 between Inventiva and Hepalys to develop and commercialize lanifibranor in Japan and South Korea1. Under the terms of the agreement, Hepalys is responsible for conducting and financing all trials in Japan and South Korea needed to file for a new drug application in these territories. Positive results from this trial could support the initiation of a pivotal Phase 3 trial in patients in Japan with MASH, once the results of NATiV3, the pivotal Phase 3 trial currently conducted by Inventiva, are available.

The trial represents a key first step in Inventiva’s and Hepalys’s partnership, as the companies aim to enter the Japanese market with lanifibranor, if approved, where up to 2.7%2 of the Japanese population suffer from MASH.

Frederic Cren, CEO and cofounder of Inventiva, stated: “The inclusion of the first participant in the Phase 1 study in Japan testifies to the strength of our partnership with Hepalys as we progress with the development of lanifibranor with our goal to make it accessible to a significant number of MASH patients. The partnership with Hepalys enables us to start development in a key market such as Japan, where our partner's local expertise is key to the program's success.”
