Daix (France), October 12, 2020 – 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 that the U.S. Food and Drug Administration (FDA) has granted Breakthrough Therapy designation to lanifibranor, the Company’s lead drug candidate, for the treatment of NASH. Lanifibranor is believed to be the first drug candidate to be granted this status for the treatment of NASH since January 2015.
The Breakthrough Therapy designation by the FDA is intended to expedite the development and review of drug candidates for serious or life-threatening conditions. To qualify for this designation, drug candidates must show preliminary clinical evidence that they may demonstrate a substantial improvement on at least one clinically significant endpoint over available therapies or over placebo if there are no approved therapies.
The designation of lanifibranor as a Breakthrough Therapy for the treatment of NASH follows the publication in June 2020 of positive topline results from Inventiva’s NATIVE Phase IIb clinical trial with lanifibranor in NASH patients. In this 24-week clinical trial, lanifibranor met the primary endpoint with a statistically significant reduction of the Steatosis Activity Fibrosis score (SAF), which combines assessments of hepatocellular inflammation and ballooning with no worsening of fibrosis in the Intention To Treat (ITT1) and Per Protocol populations (PP2). In addition, lanifibranor met key secondary endpoints, including NASH resolution with no worsening of fibrosis3 and improvement of liver fibrosis with no worsening of NASH4 in both ITT and PP populations. With regards to the secondary endpoints, lanifibranor is the first drug candidate to achieve statistically significant results on the FDA and European Medicine Agency (EMA) primary endpoints which are relevant for seeking accelerated approval during Phase III clinical development.
Inventiva is expected to hold the end of NATIVE Phase IIb clinical trial meeting with the FDA and to receive regulatory feedback from the EMA during the fourth quarter of 2020 with the initiation of the Phase III clinical trial evaluating lanifibranor in NASH planned for the first half of 2021.
Frédéric Cren, Chairman, Chief Executive Officer and cofounder of Inventiva, commented: “Ahead of our end of Phase IIb meeting with the FDA later this year, the Breakthrough Therapy designation for lanifibranor is a fantastic achievement and a regulatory recognition of the significant clinical benefits lanifibranor could provide to NASH patients as shown in our recent NATIVE Phase IIb clinical trial. This new status will allow us to pursue lanifibranor’s development towards a safe and effective treatment for this devastating disease and we look forward to continue working closely with the FDA to this end.”
About Breakthrough Therapy designation5
Breakthrough Therapy designation is a process designed to expedite the development and review of drugs in the United States that are intended to treat a serious condition and preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over available therapy on a clinically significant endpoint(s).
A drug that receives Breakthrough Therapy designation is eligible for the following:
- All Fast Track designation features ;
- Intensive guidance on an efficient drug development program, beginning as early as Phase 1 ;
- Organizational commitment involving senior managers.
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.
About the NATIVE Phase IIb trial
The NATIVE (NAsh Trial to Validate IVA337 Efficacy) clinical trial was a 24-week randomized, double-blind, placebo-controlled Phase IIb clinical trial evaluating lanifibranor for the treatment of patients with NASH. The main purpose of the trial was to assess the efficacy of lanifibranor in improving liver inflammation and ballooning, the two histological markers included in the definition of the regulatory endpoint of NASH resolution. To be considered for inclusion, patients were required to have: a diagnosis of NASH confirmed by liver biopsy; a cumulative score of inflammation and ballooning (as measured using the SAF scoring system) of three or four out of four, indicating the presence of moderate to severe inflammation and ballooning; a steatosis score greater than or equal to one, indicating the presence of moderate to severe steatosis; and a fibrosis score less than four, indicating the absence of cirrhosis. The primary endpoint of the trial was a reduction in the combined inflammation and ballooning score of two points compared to baseline, with no worsening fibrosis, as measured by the SAF score. Secondary endpoints included NASH resolution, improvements in each of the steatosis, inflammation, ballooning and fibrosis scores from baseline as measured using the SAF score, improvements in various other fibrosis measures, improvements in several metabolic markers, improvements in steatosis, inflammation and ballooning as measured using the NAS score (NAFLD activity score), and safety.
The trial randomized 247 patients with NASH in 71 sites in Australia, Canada, Europe, Mauritius and the United States.
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.
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. A Phase I/II clinical trial in children with MPS VI is currently under preparation following the release of positive results of the Phase IIa clinical trial in adult MPS VI patients at the end of 2019.
In parallel, Inventiva is in the process of selecting an oncology development candidate for its Hippo signalling pathway program. Furthermore, the Company has established a strategic collaboration with AbbVie in the area of autoimmune diseases. AbbVie has started the clinical development of ABBV‑157, a drug candidate for the treatment of moderate to severe psoriasis resulting from its collaboration with Inventiva. This collaboration enables Inventiva to receive milestone payments upon the achievement of pre-clinical, clinical, regulatory and commercial milestones, in addition to royalties on any approved products resulting from the collaboration.
The Company has a scientific team of approximately 70 people with deep expertise in the fields of biology, medicinal and computational chemistry, pharmacokinetics and pharmacology, as well as in clinical development. It also 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 C 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
