Strategic developments across the ACLF franchise GENFIT at The Liver Meeting 2024 GENFIT will present pre-clinical data as part of its ACLF franchise with the following posters: VS-01: Effect of VS-01 on Acute-on-Chronic Liver failure-related toxins such as lipopolysaccharide and hydrophobic bile acids in vitro (poster #1603)SRT-015: Intravenous administration with the ASK1 inhibitor SRT-015 alleviates liver injury and systemic inflammation in disease models of liver failure (poster #1597)CLM-022: Investigational drug CLM-022, a potent inhibitor of NLRP3 inflammasome-mediated pyroptosis, as a potential treatment for acute and chronic inflammatory liver diseases (poster #2232)NTZ: Efficacy of Nitazoxanide (NTZ) in Pathogen-Associated Molecular Patterns (PAMPs)-induced disease models (poster #2222) GENFIT will also lead 3 key events on ACLF: ACLF KOL Advisory Board (November 14, 2024), bringing together 9 leading experts from Europe and the United StatesACLF Patient Advocacy Council (November 16, 2024), with the participation of Professor Debbie Shawcross, MBBS PhD FRCP, Professor of Hepatology and Chronic Liver Failure, Institute of Liver Studies King’s College London, UK and EASL Vice-Secretary), the Global Liver Institute (GLI), the European Liver Patients’ Association (ELPA), and real-life patients and caregiversACLF Morning Insights session (November 17, 2024), focused on addressing unmet needs, diagnostics, and guidelines for ACLF, with Dr. Jasmohan Bajaj, Professor of Medicine in the Division of Gastroenterology, Hepatology and Nutrition at Virginia Commonwealth University and Richmond VA Medical Center in Richmond, Virginia, USA. The event will also offer an intensivist’s perspective with Dr. William Bernal, Professor of Liver Critical Care Medicine in the Liver Intensive Therapy Unit at the Institute of Liver Studies at King’s College Hospital, London and Member of the EASL-CLIF Consortium Steering Committee. It will also outline GENFIT’s clinical roadmap and highlight the patient and caregiver experience, via GLI and ELPA. Key strategic insights and emerging trends uncovered through unique sources and channels Over the last 12 months, GENFIT has made strides in understanding the ACLF continuum, enriching our body of knowledge compared to the knowledge available in the field at the time of our pivot to ACLF. Key takeaways derived from these workstreams will inform the design of on-going and upcoming trials evaluating VS-01, NTZ and SRT-015. These insights will also help further strategize the research and clinical development of CLM-022 and VS-02-HE. UNVEIL-IT®3 clinical and operational improvements: As announced in September 202410, lower than expected trial enrollment prompted a protocol amendment to better accommodate patient care logistics and comorbidities. These recent modifications require time before they can be implemented in every investigational site and before they can significantly impact the enrollment curve. Therefore, we are now guiding 2H25 for UNVEIL-IT results. The two main points of focus for our improvement efforts have been: Inclusion and exclusion criteria were overly restrictive for a patient population with multiple co-morbidities. As we accumulated data to better characterize these patients, we collaborated with investigators and KOLs to modify the protocol and better address the targeted population. Logistical challenges are inherent to the introduction of any new technology. In the case of VS-01 the necessary steps in the reconstitution process, and the limitation of a clinical trial setting, had previously restricted patient enrollment windows. By generating additional stability data, we now offer enhanced storage flexibility for study material, enabling clinical trial centers to use VS-01 more frequently. Additionally, we have been working on the development of an innovative medical device which should be available next year and will further streamline the reconstitution process. Cutting-edge processing of Real-World Evidence: An in-depth analysis of medical claims data – leveraged through advanced A.I. and machine learning techniques from a targeted U.S. population of over 270,000 patients – provided pivotal insights into risk profiles within specific patient sub-populations of the ACLF continuum, as well as differences in referral dynamics, patient journeys and clinical management practices compared to Europe. Applying sophisticated algorithms uncovered epidemiological patterns and trends within this substantial dataset, generating actionable intelligence that enhances our understanding and supports more precise, data-driven decisions across our portfolio.Preclinical research: New preclinical models have been established with leading experts, serving as key enablers to deliver valuable data aimed at improving our understanding of our portfolio potential. To date, the data already generated encompasses a range of disease models and various formulations. This approach is designed to optimize asset positioning and refine population targeting, ultimately supporting strategic decision-making and maximizing impact across our therapeutic landscape. Collaboration with learned societies: Strategic partnerships, including with the European Foundation for the Study of Chronic Liver Failure (EF CLIF) and engagement with U.S. KOLs from NACSELD11, offered important insights through unique data sources encompassing several observational studies, while also accelerating and expanding discussions with key leaders in the field. This type of collaboration places GENFIT at the forefront of international research, advancing the understanding of ACLF pathophysiology and uncovering novel approaches for the treatment of this syndrome. Data readout from 4 clinical trials anticipated by the end of 2025 Building on insights from the upcoming KOL Advisory Board and additional real-world evidence anticipated by late November 2024, GENFIT will finalize the design of two new proof-of-concept studies evaluating VS-01 and NTZ, alongside a First-in-Human study for SRT-015 with GENFIT’s formulation. These trials are expected to launch in the first half of 2025, with data readouts expected by year-end. With Phase 2 data for UNVEIL-IT trial also anticipated by the close of 2025, GENFIT will deliver four clinical data sets in 2025, advancing three clinical-stage assets of our ACLF pipeline in parallel. Preclinical assets CLM-022: Preclinical Proof of Concept expected to be obtained by end of 2024VS-02-HE: Completion of Investigational New Drug (IND) enabling studies expected in 2025 III. GNS561 in KRAS-mutated cholangiocarcinoma The phase 1b/2a clinical trial is currently ongoing and preliminary data from Phase 1b is targeted by the end of 2024. Final data is expected by the end of 2025. IV. NIS2+® in MASH During The Liver Meeting 2024, GENFIT will also present new data on NIS2+®’s3 efficacy as a monitoring tool for patients with MASH12 with the following posters: NIS2+, an effective monitoring tool for tracking disease evolution in patients with fibrotic MASH (poster #2062)NIS2+, an effective tool for monitoring MASH resolution and fibrosis improvement in patients with at-risk MASH (poster #2063)Detecting MASH resolution and fibrosis improvement with NIS2+ in patients with at-risk MASH (poster #2067) Significant progress has been made since the recognition of NIS2+ as a key tool for detecting at-risk MASH in June 202413, as our technology is now also covering screening and monitoring needs, and not just diagnostics needs. With more than 20 clinical MASH trials using our technology, more publications are referring to it, highlighting the relevance of our solution. In March 2024, Rezdiffra™ (resmetirom) was the first drug approved in MASH in the United States. As a reminder, GENFIT signed a commercial agreement with Labcorp in 2021 to provide broad clinical availability of the test to specialty and primary care physicians across the U.S. and Canada. Our business goal is now to develop an IVD version of the test, either in collaboration with a commercial partner or by ourselves.
