About Digestive Disease WeekDigestive Disease Week (DDW) is the largest international gathering of physicians, researchers and academics in the fields of gastroenterology, hepatology, endoscopy and gastrointestinal surgery. Jointly sponsored by the American Association for the Study of Liver Diseases (AASLD), the American Gastroenterological Association (AGA), the American Society for Gastrointestinal Endoscopy (ASGE) and the Society for Surgery of the Alimentary Tract (SSAT), DDW is an in-person and online meeting from May 3-6, 2025. The meeting showcases more than 5,600 abstracts and hundreds of lectures on the latest advances in GI research, medicine and technology. More information can be found at www.ddw.org. About Primary Biliary CholangitisPrimary biliary cholangitis (PBC) is a rare, progressive and chronic autoimmune disease that affects the bile ducts in the liver and is most prevalent (approximately 1 in 10,000) in women over the age of 40. PBC causes bile acid to build up in the liver, resulting in inflammation and scarring (fibrosis), which, if left untreated, can lead to cirrhosis, a liver transplant or death. About Severe Alcohol-Associated Hepatitis (sAH)Alcohol-related liver disease (ALD) as a cause of chronic liver disease is on the rise in the U.S. and is currently the leading indication for liver transplant listing overall in the U.S. Patients with severe alcohol-associated hepatitis (sAH) are now younger, with an increased representation of females compared to past decades, reflecting changing patterns of alcohol consumption in the U.S. Currently, there are no medicines with an approved indication to treat patients with sAH. About Primary Sclerosing CholangitisPrimary sclerosing cholangitis (PSC) is a rare, life-threatening, chronic cholestatic liver disease characterized by progressive destruction of bile ducts that leads to the development of cirrhosis and end-stage liver disease or cancer in a majority of patients. About the Investigational Obeticholic Acid-Bezafibrate CombinationIntercept has two ongoing Phase 2 studies (747-213 / NCT04594694, 747-214 / NCT05239468) that are exploring a range of therapeutic doses for the combination of obeticholic acid (OCA) and bezafibrate for the potential treatment of individuals with PBC. Obeticholic acid, a farnesoid X receptor (FXR) agonist, is marketed by Intercept as OCALIVA in the United States for the treatment of PBC (see below for full indication and Important Safety Information). Bezafibrate, a pan-peroxisome proliferator-activated receptor (pan-PPAR) agonist, is not approved in the United States for any indication. FXR and PPAR are distinct pathways that each play a role in PBC. Simultaneously targeting both pathways may offer the greatest potential to impact bile acid synthesis, metabolism, and clearance that underly cholestatic liver diseases. Published studies establish a clinical proof-of-concept which suggests that the combination of obeticholic acid and bezafibrate may provide additive clinical efficacy and tolerability benefits in the treatment of PBC. Obeticholic acid-bezafibrate combination therapy is investigational; safety and efficacy have not been established. About OCALIVA (obeticholic acid)OCALIVA, a farnesoid X receptor (FXR) agonist, is indicated for the treatment of adult patients with primary biliary cholangitis (PBC) without cirrhosis orwith compensated cirrhosis who do not have evidence of portal hypertension, either in combination with ursodeoxycholic acid (UDCA) with an inadequate response to UDCA or as monotherapy in patients unable to tolerate UDCA. This indication is approved under accelerated approval based on a reduction in alkaline phosphatase (ALP). An improvement in survival or disease-related symptoms has not been established. Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trials. IMPORTANT SAFETY INFORMATION WARNING: HEPATIC DECOMPENSATION AND FAILURE IN PRIMARY BILIARY CHOLANGITIS PATIENTS WITH CIRRHOSIS Hepatic decompensation and failure, sometimes fatal or resulting in liver transplant, have been reported with OCALIVA treatment in primary biliary cholangitis (PBC) patients with either compensated or decompensated cirrhosis. OCALIVA is contraindicated in PBC patients with decompensated cirrhosis, a prior decompensation event, or with compensated cirrhosis who have evidence of portal hypertension. Permanently discontinue OCALIVA in patients who develop laboratory or clinical evidence of hepatic decompensation; have compensated cirrhosis and develop evidence of portal hypertension, or experience clinically significant hepatic adverse reactions while on treatment. Contraindications OCALIVA is contraindicated in patients with: decompensated cirrhosis (e.g., Child-Pugh Class B or C) or a prior decompensation eventcompensated cirrhosis who have evidence of portal hypertension (e.g., ascites, gastroesophageal varices, persistent thrombocytopenia)complete biliary obstruction Warnings and Precautions Hepatic Decompensation and Failure in PBC Patients with Cirrhosis Hepatic decompensation and failure, sometimes fatal or resulting in liver transplant, have been reported with OCALIVA treatment in PBC patients with cirrhosis, either compensated or decompensated. Among post-marketing cases reporting it, median time to hepatic decompensation (e.g., new onset ascites) was four months for patients with compensated cirrhosis; median time to a new decompensation event (e.g., hepatic encephalopathy) was 2.5 months for patients with decompensated cirrhosis. Some of these cases occurred in patients with decompensated cirrhosis when they were treated with higher than the recommended dosage for that patient population; however, cases of hepatic decompensation and failure have continued to be reported in patients with decompensated cirrhosis even when they received the recommended dosage. Hepatotoxicity was observed in the OCALIVA clinical trials. A dose-response relationship was observed for the occurrence of hepatic adverse reactions including jaundice, worsening ascites, and primary biliary cholangitis flare with dosages of OCALIVA of 10 mg once daily to 50 mg once daily (up to 5-times the highest recommended dosage), as early as one month after starting treatment with OCALIVA in two 3-month, placebo-controlled clinical trials in patients with primarily early stage PBC. Routinely monitor patients for progression of PBC, including hepatic adverse reactions, with laboratory and clinical assessments to determine whether drug discontinuation is needed. Closely monitor patients with compensated cirrhosis, concomitant hepatic disease (e.g., autoimmune hepatitis, alcoholic liver disease), and/or with severe intercurrent illness for new evidence of portal hypertension (e.g., ascites, gastroesophageal varices, persistent thrombocytopenia), or increases above the upper limit of normal in total bilirubin, direct bilirubin, or prothrombin time to determine whether drug discontinuation is needed. Permanently discontinue OCALIVA in patients who develop laboratory or clinical evidence of hepatic decompensation (e.g., ascites, jaundice, variceal bleeding, hepatic encephalopathy), have compensated cirrhosis and develop evidence of portal hypertension (e.g., ascites, gastroesophageal varices, persistent thrombocytopenia), experience clinically significant hepatic adverse reactions, or develop complete biliary obstruction. If severe intercurrent illness occurs, interrupt treatment with OCALIVA and monitor the patient’s liver function. After resolution of the intercurrent illness, consider the potential risks and benefits of restarting OCALIVA treatment. Severe Pruritus Severe pruritus was reported in 23% of patients in the OCALIVA 10 mg arm, 19% of patients in the OCALIVA titration arm, and 7% of patients in the placebo arm in a 12-month double-blind randomized controlled clinical trial of 216 patients. Severe pruritus was defined as intense or widespread itching, interfering with activities of daily living, or causing severe sleep disturbance, or intolerable discomfort, and typically requiring medical interventions. Consider clinical evaluation of patients with new onset or worsening severe pruritus. Management strategies include the addition of bile acid binding resins or antihistamines, OCALIVA dosage reduction, and/or temporary interruption of OCALIVA dosing. Reduction in HDL-C Patients with PBC generally exhibit hyperlipidemia characterized by a significant elevation in total cholesterol primarily due to increased levels of high-density lipoprotein-cholesterol (HDL-C). Dose-dependent reductions from baseline in mean HDL-C levels were observed at 2 weeks in OCALIVA-treated patients, 20% and 9% in the 10 mg and titration arms, respectively, compared to 2% in the placebo arm. Monitor patients for changes in serum lipid levels during treatment. For patients who do not respond to OCALIVA after one year at the highest recommended dosage that can be tolerated (maximum of 10 mg once daily), and who experience a reduction in HDL-C, weigh the potential risks against the benefits of continuing treatment. Adverse Reactions The most common adverse reactions (≥5%) are pruritus, fatigue, abdominal pain and discomfort, rash, oropharyngeal pain, dizziness, constipation, arthralgia, thyroid function abnormality, and eczema. Drug Interactions Bile Acid Binding Resins Bile acid binding resins such as cholestyramine, colestipol, or colesevelam adsorb and reduce bile acid absorption and may reduce the absorption, systemic exposure, and efficacy of OCALIVA. If taking a bile acid binding resin, take OCALIVA at least four hours before or four hours after taking the bile acid binding resin, or at as great an interval as possible.Warfarin The International Normalized Ratio (INR) decreased following coadministration of warfarin and OCALIVA. Monitor INR and adjust the dose of warfarin, as needed, to maintain the target INR range when co-administering OCALIVA and warfarin.CYP1A2 Substrates with Narrow Therapeutic Index Obeticholic acid may increase the exposure to concomitant drugs that are CYP1A2 substrates. Therapeutic monitoring of CYP1A2 substrates with a narrow therapeutic index (e.g., theophylline and tizanidine) is recommended when co-administered with OCALIVA.Inhibitors of Bile Salt Efflux Pump Avoid concomitant use of inhibitors of the bile salt efflux pump (BSEP) such as cyclosporine. Concomitant medications that inhibit canalicular membrane bile acid transporters such as the BSEP may exacerbate accumulation of conjugated bile salts including taurine conjugate of obeticholic acid in the liver and result in clinical symptoms. If concomitant use is deemed necessary, monitor serum transaminases and bilirubin. Please click here for Full Prescribing Information, including boxed WARNING.

Ipsen presents 3 late-breaking presentations and 8 abstracts across rare cholestatic liver disease portfolio at AASLD 2024 PARIS, FRANCE, 18 November, 2024 Ipsen (Euronext: IPN; ADR: IPSEY) today announced data at the American Association for the Study of Liver Diseases (AASLD) assessing the long-term efficacy and safety of patients treated with Bylvay® from two Phase III open-label extension studies: late-breaking abstract (#5045) on PEDFIC 2 in Progressive Familial Intrahepatic Cholestasis (PFIC) and oral presentation ASSERT-EXT (#50) in Alagille syndrome (ALGS). Sustained efficacy data and improvements in height, weight and sleep measures were observed for patients treated with Bylvay for at least 72 weeks in both rare cholestatic diseases. “We know from our work with patient communities that receiving a diagnosis of PFIC and ALGS can be overwhelming in a patient or caregivers’ life. Disease symptoms like severe itch can have an impact on the whole family,” said Sandra Silvestri, EVP Chief Medical Officer, Ipsen. “Data suggesting Bylvay-treated patients experienced sustained efficacy, and which support the safety and tolerability profile seen in previous clinical trials, are important. Ipsen is committed to being the leader across rare cholestatic liver diseases and we are just getting started.” PEDFIC 2 Study in PFIC “These open-label extension data from PEDFIC 2 suggest that the initial reduction in pruritus and in serum bile acid levels achieved following initiation of odevixibat are being sustained into the longer term,” said Dr. Richard J. Thompson, Professor of Molecular Hepatology, King’s College London and principal investigator of the PEDFIC 2 trial. “We are also observing reductions in both pruritus and serum bile acid across a number of PFIC subtypes. This is important information for our understanding of the therapeutic management of our patients living with PFIC.” PEDFIC 2 was an open-label extension study (n=116; patients from PEDFIC 1 Bylvay and placebo cohorts at week 24, and new Bylvay-naïve patients of any age and PFIC subtype), evaluating the efficacy and safety of Bylvay through 72 weeks (n=83).1 The data showed a clinically meaningful 1-point reduction in pruritus score at week 72 in 42 percent of patients <18 years old with PFIC 1 and 2 who transitioned to Bylvay at 24 weeks (n=5/12) and 61 percent of patients with any type of PFIC and of any age excluding episodic (n=19/31). Rapid initial pruritus scores achieved by week 4 were sustained for patients who remained on treatment. At 72 weeks, the mean change in serum bile acid (sBA) levels from patients who transition to Bylvay at week 24 (n=15) was –104.00 µmol/L and Bylvay-treated patients (n=43) was -57.97 µmol/L . Beyond the clinically meaningful and sustained improvements seen in pruritus and sBA levels, height, weight and sleep increases were reported at 72 weeks in Bylvay-treated patients. Most adverse events in Bylvay-treated patients over the duration of the study were reported as mild or moderate. The most common were gastrointestinal (17.2 percent; n=20/116), including diarrhea (12 percent; n=14/116). In two cases, diarrhea led to one treatment interruption and one discontinuation. Assert-EXT Study in ALGS“The sustained improvements we've seen in Bylvay-treated individuals living with Alagille syndrome are encouraging,” said Dr. Nadia Ovchinsky, Chief, Division of Gastroenterology and Hepatology, Hassenfeld Children's Hospital at NYU Langone, New York. and principal investigator of the ASSERT trial. “These results not only show the potential to manage symptoms like pruritus, which can be extremely difficult for children and their parents to manage, but we’re also seeing a consistent safety profile over the longer term with sustained tolerability.” In ASSERT-EXT, the open-label extension study (n=50) evaluating the long-term efficacy and safety of Bylvay in ALGS patients (ages 1-15.9 years) through 72 weeks (n=44), sustained improvements were observed in pruritus and sBA levels through 72 weeks.2 At week 72, 93 percent (n=28/30) of patients who received Bylvay throughout the 24 weeks ASSERT trial and 77 percent (n=10/13) of those who transitioned from placebo to Bylvay at week 24 experienced a clinically meaningful ≥1 point reduction in pruritus score. Reductions in sBA levels were also observed in patients treated with Bylvay for 72 weeks showing a mean reduction of 124 µmol/L in those who continuously received Bylvay and a mean reduction of 139 µmol/L in patients who transitioned from placebo to Bylvay. Mean changes from baseline were observed in height (8.2 cm) and weight (2.8 kg) on continuous Bylvay use and for patients who transitioned from placebo to Bylvay, height (10.7 cm) and weight (3.3 kg) mean changes were also reported. Improvements in sleep were observed from weeks 24 to 72 across all four sleep parameters (n=43), including proportion of days seeing blood due to scratching, proportion of days needing help falling asleep, proportion of days needing soothing and daytime tiredness. Data supports the safety profile in the ASSERT clinical trial for Bylvay. Treatment emergent adverse event (TEAE) occurred in 18 percent (n=6/33) of patients who continuously received Bylvay and 41 percent (n=7/17) of patients who transitioned from placebo to Bylvay. Most adverse events were mild or moderate with diarrhea as the most common TEAE. One TEAE led to discontinuation. About PFIC and ALGSPFIC is a group of rare genetic disorders in which bile acids build up in the liver, causing damage, which may result in liver failure. ALGS is also a rare genetic disorder, affecting multiple organs including the liver, heart, skeleton, eyes and kidneys. Without early diagnosis and effective management, people living with PFIC and ALGS may need a liver transplant. Debilitating itch, caused as a result of the serum bile acid build up, is one of the most common symptoms of both PFIC and ALGS, significantly impacting sleep and daily activities and resulting in skin mutilation, loss of sleep, irritability, and poor attention.

About Bylvay (odevixibat)Odevixibat is a once-daily non-systemic ileal bile acid transport (IBAT) inhibitor approved under the brand name Bylvay® in the U.S. as the first drug treatment option for patients 3 months of age and older living with cholestatic pruritus due to progressive familial intrahepatic cholestasis (PFIC). BYLVAY may not be effective in a subgroup of PFIC type 2 patients with specific ABCB11 variants resulting in non-functional or complete absence of the bile salt export pump protein. Odevixibat was also approved in June 2021 in the E.U. under the brand name Bylvay®, as the first drug treatment option for all types of PFIC in patients aged 6 months or older. Bylvay has received orphan exclusivity for the treatment of PFIC in the U.S. and E.U. In June 2023 Bylvay was approved in the U.S. for the treatment of cholestatic pruritus in patients from 12 months of age with Alagille syndrome (ALGS) and received orphan exclusivity for ALGS. In September 2024, odevixibat was approved in the E.U under the brand name Kayfanda® for the treatment of cholestatic pruritus in ALGS in patients aged 6 months or older. IMPORTANT SAFETY INFORMATION – U.S.Warnings and Precautions: Liver Test AbnormalitiesPatients who enrolled in PFIC and ALGS clinical trials had abnormal liver tests at baseline. In clinical trials, treatment-emergent elevations of liver tests or worsening of liver tests relative to baseline values were observed. Most abnormalities included elevations in aspartate aminotransferase (AST), alanine transaminase (ALT) in PFIC and ALGS, and total and direct bilirubin in PFIC clinical trials. No patients permanently discontinued treatment due to liver test abnormalities. Obtain baseline liver tests and monitor during treatment. Dose reduction or treatment interruption may be required if abnormalities occur. For persistent or recurrent liver test abnormalities, consider treatment discontinuation. Permanently discontinue Bylvay if a patient progresses to portal hypertension or experiences a hepatic decompensation event. DiarrheaDiarrhea occurred in both PFIC and ALGS clinical trials in BYLVAY-treated patients at a rate greater than placebo treated patients. If diarrhea occurs with use of BYLVAY, monitor for dehydration and treat promptly. Treatment interruption or discontinuation may be required for persistent diarrhea with no alternate etiology. Fat-Soluble Vitamin (FSV) DeficiencyFat-soluble vitamins (FSV) include vitamin A, D, E, and K. PFIC and ALGS patients can have FSV deficiency at baseline, as part of their disease. BYLVAY may affect absorption of fat-soluble vitamins. Obtain baseline levels and monitor during treatment, along with any clinical manifestations. Supplement if deficiency is observed. If FSV deficiency persists or worsens despite FSV supplementation, discontinue treatment. ADVERSE REACTIONSALGS: The most common adverse reactions (>5%) are diarrhea, abdominal pain, hematoma, and decreased weight.PFIC: The most common adverse reactions (>2%) are diarrhea, liver test abnormalities, vomiting, abdominal pain, and fat-soluble vitamin deficiency. DRUG INTERACTIONSFor patients taking bile acid binding resins, take BYLVAY at least 4 hours before or 4 hours after administering, as bile acid binding resins may bind to and reduce BYLVAY efficacy. USE IN SPECIFIC POPULATIONSThere are no human data on BYLVAY use in pregnant persons to establish a drug-associated risk of major birth defects, miscarriage, or adverse developmental outcomes. Based on findings from animal reproduction studies, BYLVAY may cause cardiac malformations when a fetus is exposed during pregnancy. There is a pregnancy safety study that monitors pregnancy outcomes in women exposed to BYLVAY during pregnancy. Pregnant women exposed to BYLVAY, or their healthcare providers, should report BYLVAY exposure by calling 1-855-463-5127.

ENDS About PEDFIC 1 and 2PEDFIC 1 was a 24-week double-blind, randomized, placebo-controlled trial that evaluated the efficacy and tolerability of two doses of odevixibat in reducing pruritus and serum bile acid levels in children with PFIC 1 or 2. PEDFIC 2 is a 72-week open label extension trial, which consisted of children from PEDFIC 1 who received either Bylvay (cohort 1a) or placebo (cohort 1b) and a new cohort (2) of Bylvay-naïve patients of any age and PFIC subtype. PEDFIC is the largest, global, Phase III trial ever conducted in PFIC. PEDFIC 1 (NCT03566238) was a 24-week double-blind, randomized (1:1:1), placebo-controlled trial that evaluated the efficacy and tolerability of two doses of odevixibat in reducing pruritus and serum bile acid levels in children with PFIC 1 or 2. Participants were randomly allocated to receive placebo (n=20), odevixibat 40 μg/kg (n=23), or odevixibat 120 μg/kg (n=19) once a day. The results were published in The Lancet.3 PEDFIC 2 (NCT03659916), an open-label extension of PEDFIC 1, is a 72-week trial that aimed to evaluate the efficacy and tolerability of odevixibat 120 µg/kg once a day in patients with PFIC. Patients were divided into two cohorts: Cohort 1 (n=56) which consisted of children with PFIC 1 or 2 from PEDFIC 1 who received odevixibat (Cohort 1a: n= 37) or placebo (Cohort 1b: n=19), respectively, and Cohort 2 (n=60) which consisted of newly enrolled, odevixibat-naïve patients of any age and PFIC subtype. Interim results were published in The Journal of Hepatology.4 About ASSERT and ASSERT-EXTASSERT (NCT04674761) was a 24-week double-blind, randomized, placebo-controlled trial with an open-label long term extension. ASSERT evaluated the safety and efficacy of 120 µg /kg once-daily odevixibat vs placebo for the treatment of cholestatic pruritus in patients with Alagille syndrome (ALGS). The trial enrolled 52 patients of any age with a genetically confirmed diagnosis of ALGS. The results were published in The Lancet.5 In ASSERT-EXT (NCT05035030), ASSERT’s ongoing open-label extension, all trial participants received 120 μg/kg of odevixibat once daily for 72-weeks after the double-blind treatment period completed. In both ASSERT and ASSERT-EXT, the investigators looked for changes in pruritus, serum bile acid concentrations, sleep, and treatment-emergent adverse events.

Such statements involve known and unknown risks and uncertainties that may cause actual results, performance or events to differ materially from those anticipated herein. All of the above risks could affect Ipsen’s future ability to achieve its financial targets, which were set assuming reasonable macroeconomic conditions based on the information available today. Use of the words ‘believes’, ‘anticipates’ and ‘expects’ and similar expressions are intended to identify forward-looking statements, including Ipsen’s expectations regarding future events, including regulatory filings and determinations. Moreover, the targets described in this document were prepared without taking into account external-growth assumptions and potential future acquisitions, which may alter these parameters. These objectives are based on data and assumptions regarded as reasonable by Ipsen. These targets depend on conditions or facts likely to happen in the future, and not exclusively on historical data. Actual results may depart significantly from these targets given the occurrence of certain risks and uncertainties, notably the fact that a promising medicine in early development phase or clinical trial may end up never being launched on the market or reaching its commercial targets, notably for regulatory or competition reasons. Ipsen must face or might face competition from generic medicine that might translate into a loss of market share. Furthermore, the research and development process involves several stages each of which involves the substantial risk that Ipsen may fail to achieve its objectives and be forced to abandon its efforts with regards to a medicine in which it has invested significant sums. Therefore, Ipsen cannot be certain that favorable results obtained during preclinical trials will be confirmed subsequently during clinical trials, or that the results of clinical trials will be sufficient to demonstrate the safe and effective nature of the medicine concerned. There can be no guarantees a medicine will receive the necessary regulatory approvals or that the medicine will prove to be commercially successful. If underlying assumptions prove inaccurate or risks or uncertainties materialize, actual results may differ materially from those set forth in the forward-looking statements. Other risks and uncertainties include but are not limited to, general industry conditions and competition; general economic factors, including interest rate and currency exchange rate fluctuations; the impact of pharmaceutical industry regulation and healthcare legislation; global trends toward healthcare cost containment; technological advances, new medicine and patents attained by competitors; challenges inherent in new-medicine development, including obtaining regulatory approval; Ipsen’s ability to accurately predict future market conditions; manufacturing difficulties or delays; financial instability of international economies and sovereign risk; dependence on the effectiveness of Ipsen’s patents and other protections for innovative medicines; and the exposure to litigation, including patent litigation, and/or regulatory actions. Ipsen also depends on third parties to develop and market some of its medicines which could potentially generate substantial royalties; these partners could behave in such ways which could cause damage to Ipsen’s activities and financial results. Ipsen cannot be certain that its partners will fulfil their obligations. It might be unable to obtain any benefit from those agreements. A default by any of Ipsen’s partners could generate lower revenues than expected. Such situations could have a negative impact on Ipsen’s business, financial position or performance. Ipsen expressly disclaims any obligation or undertaking to update or revise any forward-looking statements, targets or estimates contained in this press release to reflect any change in events, conditions, assumptions or circumstances on which any such statements are based, unless so required by applicable law. Ipsen’s business is subject to the risk factors outlined in its registration documents filed with the French Autorité des Marchés Financiers. The risks and uncertainties set out are not exhaustive and the reader is advised to refer to Ipsen’s latest Universal Registration Document, available on ipsen.com. References 1Thompson RJ, et al.
