PARIS, FRANCE, 20 September 2024 – Ipsen (Euronext: IPN; ADR: IPSEY) announced today that the European Commission has conditionally approved Iqirvo^® (elafibranor) 80mg tablets for the treatment of primary biliary cholangitis (PBC) in combination with ursodeoxycholic acid (UDCA) in adults with an inadequate response to UDCA or as a monotherapy in patients unable to tolerate UDCA. Iqirvo is a first-in-class, oral, peroxisome proliferator-activated receptor (PPAR) agonist, that exerts an effect on the proteins PPARα and PPARδ, thought to be key regulators of bile acid, inflammation and fibrosis.

“We are delighted that Iqirvo is approved in the E.U. as an effective new option for the treatment of people living with PBC. This is a rare liver disease, predominantly found in women, which hasn’t seen new innovation for nearly a decade. This is despite up to half of patients being intolerant or unresponsive to current therapies,” said Sandra Silvestri, Chief Medical Officer, Ipsen. “For those patients with PBC that may be at risk of disease progression and who continue to suffer from debilitating symptoms of the disease, we are delighted to be able to offer an effective treatment choice.”

Approval of Iqirvo was based on data from the phase III ELATIVE¹ trial, which demonstrated a statistically significant treatment benefit with a 47% placebo-adjusted difference (P<0.001) between patients on Iqirvo 80mg (51%) compared with patients on placebo (4%) achieving a biochemical response. A greater decrease in PBC Worst Itch-NRS score from baseline was also observed for patients on Iqirvo versus placebo, but this was not statistically significant. Treatment with Iqirvo was associated with an improvement in pruritus (itch) as evidenced by a greater reduction in PBC-40 itch and 5-D itch total scores compared to placebo. Similar percentages of patients in the Iqirvo group and the placebo group experienced adverse events, treatment-related adverse events, severe or serious adverse events or adverse events leading to discontinuation.

“It is a positive development in the treatment and management of PBC that we have a new, efficacious and well-tolerated treatment for our patients living with the condition,” said Dr Marco Carbone, Professor of Gastroenterology, University of Milano-Bicocca and Consultant Hepatologist, the Niguarda Liver Transplant Centre, Milan. “PBC is a progressive liver disease that can lead to liver failure and in some people the need for liver transplantation. So, this new medicine, that has demonstrated its potential in managing disease progression, as well as reducing itch, a symptom that can have a detrimental effect on patients’ quality of life, is positive news for doctors and their patients.”

“PBC is a very personal disease which affects everyone differently. Some people may be more symptomatic with extreme fatigue or severe itch. For others there are no symptoms, but their biomarker levels are poor, suggesting the disease is not being controlled. This means that an individualized approach to management and treatment is needed for each patient,” said Patient Advocate, Mrs Sindee Weinbaum from European Liver Patients’ Association. “Patients need to be able to partner with their doctors and have constructive conversations about what they personally need to manage the PBC they are living with. So, it is great news to have a new treatment choice for the many people who are living with PBC that is not under control.”

About PBC
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’s daily lives through debilitating symptoms including most commonly pruritus and fatigue.

About Iqirvo (elafibranor)
Iqirvo (pronounced EYE-KER-VO) is an oral, once-daily, peroxisome proliferator-activated receptor (PPAR) agonist, which exerts an effect on PPARα and PPARδ. Activation of PPARα and PPARδ decreases bile toxicity and improves cholestasis by modulating bile acid synthesis, detoxification and transporters. Activation of PPARα and PPARδ also has anti-inflammatory effects by acting on different pathways. The benefits of Iqirvo are its ability to reduce alkaline phosphatase and bilirubin levels in adults with PBC. Iqirvo is therefore expected to have clinical benefits such as delayed development of liver fibrosis, cirrhosis, liver transplant and death.¹ In 2019, Iqirvo was granted Breakthrough Therapy Designation by the U.S Food and Drug Administration (FDA) in adults with PBC who have an inadequate response to ursodeoxycholic acid (UDCA) the existing first-line therapy for PBC. Iqirvo has been granted accelerated approval in the US in June 2024 and conditional approval in EU in September 2024 for the treatment of primary biliary cholangitis (PBC) in combination with ursodeoxycholic acid (UDCA) in adults who have an inadequate response to UDCA, or as monotherapy in patients unable to tolerate UDCA. These approvals are contingent on the further verification of clinical benefit. Iqirvo is currently in regulatory processes with other authorities including the UK Medicines and Healthcare products Regulatory Agency (MHRA). Iqirvo (elafibranor) was developed by GENFIT. Ipsen licensed the exclusive worldwide rights (except China, Hong Kong, Taiwan and Macau) to elafibranor from GENFIT in 2021.

About ELATIVE
ELATIVE was a multi-center, randomized, double-blind, placebo-controlled Phase III clinical trial (NCT04526665). ELATIVE evaluated 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 continued to receive UDCA in combination with elafibranor or placebo, while patients unable to tolerate UDCA received only elafibranor or placebo. Patients continued their assigned treatment after Week 52 until all patients had completed their treatment or for a maximum of 104 weeks. The open-label long-term extension study of ELATIVE remains ongoing, where patients with PBC may receive elafibranor for up to 5 years. In the trial, the composite endpoint biochemical response is defined as alkaline phosphatase (ALP) <1.67 x upper limit of normal (ULN), an ALP decrease ≥ 15 percent and total bilirubin (TB) ≤ 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. Full results of the ELATIVE 52-week study have been published in the New England Journal of Medicine (NEJM).

Important safety information and recommendations for the use of Iqirvo will be detailed in the Summary of Product Characteristics (SmPC), published in the European public assessment report (EPAR) and available in all official EU languages. The full SmPC will be found at: Iqirvo, INN-elafibranor (europa.eu)
