PARIS, FRANCE, 13 November, 2023<\/strong> \u2013 Ipsen (Euronext: IPN; ADR: IPSEY) and GENFIT (Nasdaq and Euronext: GNFT) today announced full results from the pivotal Phase III ELATIVE\u00ae<\/sup> trial, which are being presented in a late-breaking oral session (Abstract #484, Monday, 13 November at 16.45 EST)at the American Association for the Study of Liver Disease (AASLD) and simultaneously published in the New England Journal of Medicine<\/a> (NEJM). This trial evaluated the efficacy and safety of investigational elafibranor, an oral, dual PPAR \u03b1,\u03b4 agonist, as a potential novel class of treatment for patients with the rare, autoimmune cholestatic liver disease, primary biliary cholangitis (PBC).<\/p>\n\n\n\n Results show statistically significant improvements in biomarkers of disease progression across key endpoints with a significant treatment benefit achieved in the primary composite endpoint, demonstrating a 47% placebo-adjusted difference (P<0.001) between patients on elafibranor 80mg (51%) compared with patients on placebo (4%) achieving a biochemical response. In the trial, a biochemical response is defined as alkaline phosphatase (ALP) <1.67 x upper limit of normal (ULN), an ALP decrease \u2265 15 percent and total bilirubin (TB) \u2264 ULN at 52 weeks. ALP and bilirubin are important predictors of PBC disease progression. Reductions in levels of both can indicate reduced cholestatic injury and improved liver function.<\/p>\n\n\n\n Only patients receiving elafibranor achieved normalization of ALP (upper limit of normal 104 U\/L in females and 129 U\/L in males) at Week 52 (15% vs 0% placebo, P=0.002), a key secondary endpoint of the trial. The significant biochemical effect of elafibranor measured by ALP reduction was further supported by data demonstrating reductions from baseline in ALP levels were rapid, seen as early as Week 4 in the elafibranor group, and were sustained through Week 52, with a decrease in ALP of 41% on elafibranor compared with placebo.<\/a><\/p>\n\n\n\n \u201cWhen managing PBC our first goal is to effectively control the disease progression which can lead to liver failure. The results from ELATIVE provide compelling evidence that elafibranor has the potential to achieve this goal, with evidence of a highly significant treatment benefit that is associated with improved clinical outcomes,\u201d said Dr Christopher Bowlus, Professor of Gastroenterology and Hepatology, University of California Davis, U.S. \u201cIn addition, our patients need relief from the significant symptom burden of PBC, particularly those with moderate to severe itch. Data from ELATIVE demonstrated the possibility of improved pruritus for patients taking elafibranor compared with those on placebo. Taken together, these data suggest elafibranor could offer an effective new treatment opportunity for PBC management.\u201d<\/p>\n\n\n\n ELATIVE investigated the effect of treatment with elafibranor on pruritus (severe itch) across three separate patient-reported outcome measures. On the key secondary endpoint using the PBC Worst Itch NRS score, the reduction of pruritus observed for elafibranor versus placebo was not statistically significant (LS mean, \u20131.93 versus \u20131.15; difference, \u20130.78; 95% CI, \u20131.99 to 0.42; P=0.20). <\/a>Two other secondary patient-reported outcome measures were used to assess itch, and greater reductions in pruritus were observed with elafibranor compared with placebo at Week 52, according to the itch domain of PBC-40 quality of life questionnaire (LS mean difference -2.3; 95% CI, -4.0 to -0.7) and 5-D Itch total score (LS mean difference, -3.0; 95% CI, -5.5 to -0.5).<\/p>\n\n\n\n \u201cWe believe these data suggest that elafibranor could be a paradigm-changing treatment meeting the unmet need for an effective second-line option,\u201d said Christelle Huguet, EVP and Head of Research and Development, Ipsen. \u201cThese data from ELATIVE have provided a better understanding of how we can effectively manage both disease progression and the symptom burden still experienced by many people living with PBC. It would not have been possible for us to investigate the potential for new innovative treatments without the involvement of the patients and their wider families and caregivers, to whom we are immensely grateful. We are also enormously grateful to the study investigators, who have supported us and provided us with the benefit of their expertise in designing and running this study.\u201d<\/p>\n\n\n\n PBC is a rare, autoimmune, cholestatic liver disease, affecting approximately nine women for every one man. A build-up of bile and toxins (cholestasis) and chronic inflammation causes irreversible fibrosis (scarring) of the liver and destruction of the bile ducts. It is a life-long condition that can worsen over time if not effectively treated, leading to liver transplant and in some cases, premature death. PBC impacts patient\u2019s daily lives through debilitating symptoms including most commonly pruritus and fatigue. Currently, there are no approved treatments available that can effectively manage both disease progression and life-impacting symptoms.<\/p>\n\n\n\n \u201cLiving with PBC can be very challenging for many people. The fear of the disease progressing hangs over you, and you have to manage as best you can with the daily symptom burden, symptoms that can sometimes be so debilitating it takes every ounce of strength to get through another day,\u201d explained Mo Christie, Head of Patient Services, PBC Foundation, UK. \u201cAs someone who is living with PBC, I appreciate the need for clinicians, other patients, and families to understand the condition and the impact that coming to terms with living with an incurable condition can have on a person\u2019s life. The impact can be enormous, so it is vitally important to all aspects of our lives that we can access knowledge, care and effective medicines, when we see our clinicians.\u201d<\/p>\n\n\n\n Elafibranor was well tolerated in the trial. Similar percentages of patients in the treatment group and the placebo group experienced adverse events, treatment-related adverse events, severe or serious adverse events or adverse events leading to discontinuation. Adverse events occurring in >10% of patients and more frequently on elafibranor versus placebo included abdominal pain, diarrhea, nausea, and vomiting. Elafibranor has a well-documented safety profile across a broad patient population and is consistent with cumulative safety data from past elafibranor trials in other indications, including NASH.<\/p>\n\n\n\n Data from ELATIVE are being used to support submissions for elafibranor as a treatment for PBC with regulatory authorities worldwide.<\/p>\n\n\n\n ENDS<\/strong><\/strong><\/p>\n\n\n\n ELATIVE<\/strong><\/p>\n\n\n\n ELATIVE is a multi-center, randomized, double-blind, placebo-controlled Phase III clinical trial, with an open-label long-term extension (NCT04526665). ELATIVE is evaluating the efficacy and safety of elafibranor 80mg once daily versus placebo for the treatment of patients with PBC with an inadequate response or intolerance to ursodeoxycholic acid (UDCA), the existing first-line therapy for PBC. The trial enrolled 161 patients who were randomized 2:1 to receive elafibranor 80mg once daily or placebo. Patients with an inadequate response to UDCA would continue to receive UDCA in combination with elafibranor or placebo, while patients unable to tolerate UDCA would receive only elafibranor or placebo.<\/p>\n\n\n\n Elafibranor<\/strong><\/p>\n\n\n\n Elafibranor is a novel, oral, once-daily, dual peroxisome activated receptor (PPAR) alpha\/delta (\u03b1,\u03b4) agonist<\/a>, currently under investigation as a treatment for patients with PBC, a rare liver disease. Concurrent \u03b1,\u03b4 activation targets inflammation, cholestasis and fibrosis in PBC. In 2019, elafibranor was granted a Breakthrough Therapy Designation by the FDA in adults with PBC who have an inadequate response to UDCA. Elafibranor has not received approval by regulatory authorities anywhere in the world.<\/p>\n\n\n\n Ipsen <\/strong><\/p>\n\n\n\n Ipsen is a global, mid-sized biopharmaceutical company focused on transformative medicines in Oncology, Rare Disease and Neuroscience.
