Rifampin

Ipsen presents 3 late-breaking presentations and 8 abstracts across rare cholestatic liver disease portfolio at AASLD 2024Iqirvo approved for use in the U.S. in June 2024, in the E.U. in September 2024 and in the U.K. in October 2024 PARIS, FRANCE, 15 November 2024 Ipsen (Euronext: IPN; ADR: IPSEY) announced today late-breaking data for Iqirvo® (elafibranor 80 mg tablets) from an interim analysis of the ongoing open-label extension of the Phase III ELATIVE® study at the American Association for the Study of Liver Disease (AASLD) congress. The late-breaking presentations (Abstract #5041 and Abstract #5042) report on biomarkers of cholestasis, stabilization of surrogate markers of liver fibrosis and moderate-to-severe pruritus data for up to three years in Iqirvo-treated patients. Additionally, exploratory endpoints in fatigue and sleep were evaluated using patient-reported outcomes tools. “Over three years, Iqirvo data suggest sustained efficacy and support the safety profile of the medicine. Importantly, when patients tell me they are less impacted by itch and fatigue—that matters to me as a physician,” said Dr. Kris Kowdley, Director at The Liver Institute Northwest, Washington and a primary investigator on the ELATIVE study. “Treatment with Iqirvo had an impact on symptoms of pruritus and surrogate markers of fibrosis, which are important findings for people living with PBC.” “Fatigue is a symptom often reported by people living with PBC and is also very challenging to manage,” said Dr. Mark Swain, Department of Medicine, Cumming School of Medicine, University of Calgary, Canada. “Patients treated with Iqirvo reported improvement in fatigue and sleep, across several patient-reported outcome measures.” The open-label extension (OLE) included 138 patients who completed the double-blind period of the Phase III ELATIVE® study1. This interim analysis was performed after at least one year of treatment with Iqirvo in the OLE (up to three years total). In patients receiving three years of continuous treatment with Iqirvo across the double-blind period and OLE (n=13), 85 percent had a biochemical response (n=11/13; ALP <1.67 x ULN, with ≥ 15% reduction from baseline and total bilirubin ≤ ULN) and 39 percent achieved ALP normalization (n=5/13) at week 156. Surrogate markers of liver fibrosis, liver stiffness measurements (n=23) and enhanced liver fibrosis (ELF™) (n=19) scores, suggest stabilization when measured from baseline to week 130. In patients continuously receiving Iqirvo for up to 156 weeks, pruritus improvements were sustained for patients with moderate or severe pruritus at baseline (n=5). No new safety findings were observed. The most common treatment-emergent adverse events (>10 percent) occurring more frequently in patients treated with Iqirvo than placebo in the double-blind period of the trial (abdominal pain, diarrhea, nausea and vomiting) were also reported in the OLE. The impact of Iqirvo on fatigue and sleep were investigated as an exploratory endpoint in the OLE.2 Changes in fatigue or sleepiness (including normal sleep) were reviewed from baseline to week 104 looking at the minimal clinically important differences and categorical changes (n=48). Fatigue and sleep improvements for patients treated with Iqirvo were observed at week 104 across three patient-reported outcome (PRO) tools. In patients with moderate-to-severe fatigue or excessive sleepiness at baseline, clinically meaningful improvements were observed after 104 weeks of treatment with Iqirvo in 56 percent (n=18) of patients according to the PRO Measurement Information System (PROMIS) Fatigue Short Form 7a, 50 percent (n=24) of patients according to the fatigue domain of the PBC-40, and 69 percent (n=16) of patients according to the Epworth Sleepiness Scale (ESS). These are interim data and have not been submitted to regulatory agencies. A confirmatory study of Iqirvo is ongoing (NCT06016842). “People living with PBC tell us just how devastating this disease can be for patients and their families,” said Sandra Silvestri, EVP and Chief Medical Officer, Ipsen. “Data like these continue to provide prescribers with a clear rationale for Iqirvo. As the first-in-class PPAR approved for the treatment of PBC, Iqirvo is on track to be the treatment of choice for patients living with PBC. Ipsen is committed to being a leader the rare liver community can count on.” About PBCPBC is a rare, autoimmune, cholestatic liver disease where a build-up of bile and toxins (cholestasis) and chronic inflammation causes irreversible fibrosis (scarring) of the liver and destruction of the bile ducts. Impacting approximately 100,000 people in the U.S.,3 the majority being women, PBC is a lifelong condition that can worsen over time if not effectively treated, may lead to liver transplant and in some cases, premature death. The high symptom burden of PBC can also have an impact on daily life.

About Iqirvo® (elafibranor) 80 mg tabletIqirvo is an oral, once-daily, peroxisome proliferator-activated receptor (PPAR), indicated 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. While the mechanism is not well understood, pharmacological activity that is potentially relevant to Iqirvo therapeutic effects includes inhibition of bile acid synthesis through activation of PPAR-alpha and PPAR-delta. 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 was granted U.S. FDA accelerated approval in June 2024, EU conditional approval by the EMA in September 2024 and UK Medicines and Healthcare products Regulatory Agency (MHRA) approval in October 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. The FDA and EMA approvals are contingent on the further verification of clinical benefit. Iqirvo is currently in regulatory processes with other authorities. 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. INDICATIONIQIRVO® is indicated for the treatment of primary biliary cholangitis (PBC) in combination with ursodeoxycholic acid (UDCA) in adults with an inadequate response to UDCA, or as monotherapy in adults unable to tolerate UDCA. This indication is approved under accelerated approval based on reduction of alkaline phosphatase (ALP). Improvement in survival or prevention of liver decompensation events have not been demonstrated. Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trial(s). Limitations of UseUse of IQIRVO is not recommended in patients who have or develop decompensated cirrhosis (e.g., ascites, variceal bleeding, hepatic encephalopathy). IMPORTANT SAFETY INFORMATIONMyalgia, Myopathy, and Rhabdomyolysis: Rhabdomyolysis resulting in acute kidney injury occurred in one IQIRVO-treated patient who had cirrhosis at baseline and was also taking a stable dose of an HMG-CoA reductase inhibitor (statin). Myalgia or myopathy, with or without CPK elevations, occurred in patients treated with IQIRVO alone or treated concomitantly with a stable dose of an HMG-CoA reductase inhibitor. Assess for myalgia and myopathy prior to IQIRVO initiation. Consider periodic assessment (clinical exam, CPK measurement) during treatment with IQIRVO, especially in those who have signs and symptoms of new onset or worsening of muscle pain or myopathy. Interrupt IQIRVO treatment if there is new onset or worsening of muscle pain, or myopathy, or rhabdomyolysis. Fractures: Fractures occurred in 6% of IQIRVO-treated patients compared to no placebo-treated patients. Consider the risk of fracture in the care of patients treated with IQIRVO and monitor bone health according to current standards of care. Adverse Effects on Fetal and Newborn Development: IQIRVO may cause fetal harm when administered during pregnancy. For females of reproductive potential, verify that the patient is not pregnant prior to initiation of therapy. Advise females of reproductive potential to use effective non-hormonal contraceptives or add a barrier method when using systemic hormonal contraceptives during treatment with IQIRVO and for 3 weeks following the last dose of IQIRVO. Drug-Induced Liver Injury: Drug-induced liver injury occurred in one patient who took IQIRVO 80 mg once daily and two patients who took IQIRVO at 1.5-times the recommended dosage, of which one presented with autoimmune-like hepatitis. The median time to onset of elevation in liver tests was 85 days. Obtain baseline clinical and laboratory assessments at treatment initiation with IQIRVO and monitor thereafter according to routine patient management. Interrupt IQIRVO treatment if liver tests (ALT, AST, total bilirubin [TB], and/or alkaline phosphatase [ALP]) worsen, or the patient develops signs and symptoms consistent with clinical hepatitis (e.g., jaundice, right upper quadrant pain, eosinophilia). Consider permanent discontinuation if liver tests worsen after restarting IQIRVO. Hypersensitivity Reactions: Hypersensitivity reactions have occurred in a clinical trial with IQIRVO at 1.5-times the recommended dosage. Three patients (0.2%) had rash or unspecified allergic reaction that occurred 2 to 30 days after IQIRVO initiation. Hypersensitivity reactions resolved after discontinuation of IQIRVO and treatment with steroids and/or antihistamines. If a severe hypersensitivity reaction occurs, permanently discontinue IQIRVO. If a mild or moderate hypersensitivity reaction occurs, interrupt IQIRVO and treat promptly. Monitor the patient until signs and symptoms resolve. If a hypersensitivity reaction recurs after IQIRVO rechallenge, then permanently discontinue IQIRVO. Biliary Obstruction: Avoid use of IQIRVO in patients with complete biliary obstruction. If biliary obstruction is suspected, interrupt IQIRVO and treat as clinically indicated. Drug-Drug Interactions IQIRVO may reduce the systemic exposure of progestin and ethinyl estradiol (CYP3A4 substrates), which may lead to contraceptive failure and/or an increase in breakthrough bleeding. Switch to effective non-hormonal contraceptives or add a barrier method when using hormonal contraceptives during treatment with IQIRVO and for at least 3 weeks after last dose. CPK elevation and/or myalgia occurred in patients on IQIRVO monotherapy. Co-administration of IQIRVO and HMG-CoA reductase inhibitors can increase the risk of myopathy. Monitor for signs and symptoms of muscle injury. Consider periodic assessment (clinical exam, CPK) during treatment. Interrupt IQIRVO treatment if there is new onset or worsening of muscle pain or myopathy. Co-administration of IQIRVO with rifampin, an inducer of metabolizing enzymes, may reduce the systemic exposure of elafibranor resulting in delayed or suboptimal biochemical response. Monitor the biochemical response (e.g., ALP and bilirubin) when patients initiate rifampin during treatment with IQIRVO. Bile acid sequestrants may interfere with IQIRVO absorption and systemic exposure, which may reduce efficacy. Administer IQIRVO at least 4 hours before or after a bile acid sequestrant, or at as great an interval as possible. Use in Special Populations Pregnancy: Based on data from animal reproduction studies, IQIRVO may cause fetal harm when administered during pregnancy. There are insufficient data from human pregnancies exposed to IQIRVO to allow an assessment of a drug-associated risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes. Report pregnancies to Ipsen Biopharmaceuticals, Inc. adverse event reporting line at 1-855-463-5127 or https://www.ipsen.com/contact-us/.Lactation: There are no data available on the presence of IQIRVO or its metabolites in human milk, or on effects of the drug on the breastfed infant or the effects on milk production. IQIRVO is not recommended during breastfeeding and for at least 3 weeks following last dose of IQIRVO because the risk to breastfed child cannot be excluded. Females and Males of Reproductive Potential: IQIRVO may cause fetal harm when administered to pregnant women. Verify the pregnancy status of females of reproductive potential prior to initiating IQIRVO. Advise females of reproductive potential to use effective contraception during treatment with IQIRVO and for 3 weeks after the final dose. The most common adverse events occurring in ≥10% of patients were weight gain (23%), abdominal pain (11%), nausea (11%), vomiting (11%), and diarrhea (11%).

FOSTER CITY, Calif.--( BUSINESS WIRE )--Gilead Sciences, Inc. (Nasdaq: GILD) today announced data from a two-and-a-half-year interim analysis from the ongoing Phase 3 ASSURE study, which showed that 81% (30 out of 37) of participants with primary biliary cholangitis (PBC) treated with Livdelzi ® (seladelpar) achieved a composite biochemical response (CBR), demonstrating significant improvements in a key measures of PBC progression. Additionally, 41% (15 out of 37) of participants achieved normalization of alkaline phosphatase (ALP) levels, a critical biomarker of liver function. These findings were unveiled as a late-breaker presentation at The Liver Meeting ® 2024 hosted by the American Association for the Study of Liver Diseases (AASLD) in San Diego, California from November 15-19. ASSURE ( NCT03301506 ) is an ongoing, open-label, study evaluating the long-term efficacy and safety of Livdelzi. ASSURE is enrolling adults with PBC who previously participated in a study of Livdelzi where a key eligibility criterion includes having an inadequate response or intolerance to ursodeoxycholic acid (UDCA). Using a data cutoff of January 31, 2024, the interim analysis represented all participants in the ASSURE study, including those who participated in prior clinical studies of Livdelzi (legacy studies) and participants from the pivotal Phase 3 RESPONSE study. Results demonstrate the safety profile of Livdelzi remains robust, with no treatment-related serious adverse events (SAEs) reported throughout the study duration. The exposure-adjusted incidence of adverse events decreased over time, with 86, 70, and 63 participants per 100 patient-years observed in years 1, 2 and 3 of treatment, respectively. Livdelzi continues to appear generally well tolerated, with no new safety signals or change in frequency of adverse events (AEs) with up to three years of exposure. These results are consistent with the results presented at the European Association for the Study of the Liver (EASL) Congress earlier this year. “ These data support what we’ve already observed with seladelpar. The long-term data from the ASSURE study reinforce that seladelpar consistently lowers ALP, offering a promising and much-needed option for patients living with this chronic liver condition,” said Eric J. Lawitz, MD, principal investigator and Medical Director of the Texas Liver Institute and a Clinical Professor of Medicine at University of Texas Health San Antonio, Texas, USA. “ ALP levels are recognized as an important surrogate marker of disease progression in PBC, and providers are shifting to view ALP normalization as a treatment goal. ALP levels are critical markers in assessing liver health, and for people with PBC who are not adequately responding to first-line therapies, reducing, or even normalizing these levels, can make a significant difference in the management of this disease.” In addition to the ASSURE data, Gilead showcased findings from two oral presentations highlighting additional analyses from the Phase 3 RESPONSE trial ( NCT04620733 ): A prespecified subgroup analysis underscored the efficacy and safety profile of Livdelzi in people living with PBC and compensated cirrhosis. At Month 12, the adjusted mean change from baseline in ALP for participants with cirrhosis on Livdelzi was -121.4 U/L (a decrease of approximately 35% from baseline) versus 23.2 U/L (an increase of approximately 6.6%) on placebo, and -134.8 U/L (a decrease of approximately 43.5%) for Livdelzi versus -18.0 U/L (a decrease of approximately 5.8%) for placebo in participants without cirrhosis. In Livdelzi participants, AEs were reported in 89% and 86% of participants with and without cirrhosis, respectively, versus 89% and 84% in placebo participants. A secondary analysis of pruritus in RESPONSE showed that among participants with a numerical rating score (NRS) of ≥4 and NRS ≥7 at baseline, Livdelzi led to near resolution (NRS of 0 or 1) of itch at Month 12 in 26.5% and 18.8% of participants, respectively, versus 0% of participants on placebo. In Livdelzi participants, AEs were reported in 87.8% and 86.1% of participants with baseline NRS ≥4 and NRS <4, respectively, versus 91.3% and 81% in placebo participants. Overall, the proportion of participants with AEs was similar for Livdelzi and placebo regardless of baseline itch severity. “ Gilead has a legacy of bringing groundbreaking treatments to people in need and Livdelzi is the first and only treatment to demonstrate statistically significant and durable improvements in both pruritus and markers of cholestasis related to the risk of disease progression,” said Timothy Watkins, MD, MSc, Vice President, Clinical Development, Inflammation Therapeutics, Gilead Sciences. “ With Livdelzi, we’ve introduced an effective and well tolerated option for people living with PBC, offering an important novel treatment option. We remain committed to advancing innovative therapies that provide real hope and improved outcomes for people facing this challenging liver disease.” In a separate analysis, which spans the Livdelzi program in PBC, Gilead highlighted findings from a large safety database of people treated with Livdelzi for up to five years, which demonstrated that Livdelzi was generally well tolerated considering cumulative use across studies. A total of 486 participants received Livdelzi 10 mg and 152 participants received placebo. The exposure-adjusted subject incidence (per 100 patient-years) for Livdelzi was 48.3 for AEs, 8.0 for SAEs, and 6.1 for liver-related AEs, as compared to 132 for AEs (rate reflective of shorter exposure time for placebo participants), 7.8 for SAEs, and 13.3 for liver-related AEs in placebo participants. There were no treatment-related SAEs. For more information on the AASLD Annual Meeting and Gilead’s presentations, please visit the AASLD website . Please see below for U.S. Indication and Important Safety Information for Livdelzi. About ASSURE (NCT03301506) ASSURE is an open label study to evaluate the long-term safety and tolerability of seladelpar in people with primary biliary cholangitis (PBC) who have already participated in other PBC clinical trials of seladelpar. The study is currently enrolling up to 500 people living with PBC from across 160 sites around the world. Participants enrolled in ASSURE at the time of this interim data analysis include participants from previous studies of seladelpar in PBC, including the Phase 3 registrational RESPONSE study and legacy clinical trials. Legacy studies include the open label Phase 2 dose-ranging study (2 mg, 5 mg, or 10 mg seladelpar), the open label Phase 3/4 long-term safety study (5 mg or 10 mg seladelpar), the Phase 3 placebo-controlled ENHANCE study (5 mg or 10 mg seladelpar vs placebo), and the ongoing open label study in people with PBC and hepatic impairment. ENHANCE and the long-term study were both terminated early. About RESPONSE (NCT04620733) RESPONSE is the pivotal Phase 3, double-blind, placebo-controlled clinical trial designed to evaluate the efficacy and safety of seladelpar in adults with primary biliary cholangitis (PBC) who have shown inadequate response or intolerance to ursodeoxycholic acid (UDCA). The trial enrolled 193 participants across multiple sites worldwide. RESPONSE assessed the key biomarker of cholestasis alkaline phosphatase (ALP) and other parameters of liver function, as well as secondary endpoints including pruritus and other patient quality of life measurements. Participants in the RESPONSE trial received a daily oral dose of 10 mg of seladelpar for 12 months. The trial also aims to address the high unmet need for effective second-line therapies for individuals with PBC. About Livdelzi Livdelzi ® (seladelpar) is an oral PPAR-delta agonist, or delpar, for the treatment of primary biliary cholangitis (PBC). PPAR-delta has been shown to regulate critical metabolic and liver disease pathways. Preclinical and clinical data indicate Livdelzi has anticholestatic, anti-inflammatory, antipruritic, and antifibrotic effects. Livdelzi has potential to help meet the current unmet need of people living with PBC, as the first and only treatment that achieved statistically significant reduction across biochemical response, alkaline phosphatase (ALP) normalization, and pruritus versus placebo. Pruritus is a common symptom that can significantly impair quality of life in people with PBC. Livdelzi (10 mg capsule) was granted accelerated approval for the treatment of PBC by the U.S. Food and Drug Administration (FDA) in August 2024. Livdelzi received FDA Breakthrough Therapy Designation, as well as Orphan Drug Designation for the treatment of people living with PBC. Seladelpar has also been accepted for review by the UK Medicines and Healthcare products Regulatory Agency (MHRA) and the European Medicines Agency (EMA). As part of the FDA accelerated approval, Gilead has committed to a confirmatory long-term outcomes study called AFFIRM, which has already been initiated in people with compensated cirrhosis. Continued approval may be contingent upon verification of clinical benefit in confirmatory trial(s). The Gilead Support Path ® Program offers information and resources to help patients who are prescribed Livdelzi understand coverage and financial options. U.S. Indication for Livdelzi Livdelzi is indicated for the treatment of primary biliary cholangitis (PBC) in combination with ursodeoxycholic acid (UDCA) in adults who have had 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 of ALP. Improvement in survival or prevention of liver decompensation events have not been demonstrated. Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trial(s). Limitations of Use: Use of Livdelzi is not recommended in patients who have or develop decompensated cirrhosis (e.g., ascites, variceal bleeding, hepatic encephalopathy). U.S. Important Safety Information for Livdelzi Warnings and Precautions Fractures: Fractures occurred in 4% of LIVDELZI-treated patients compared to no placebo-treated patients. Consider the risk of fracture in the care of patients treated with LIVDELZI and monitor bone health according to current standards of care. Liver Test Abnormalities: LIVDELZI has been associated with dose-related increases in serum transaminase (AST and ALT) levels > 3 x ULN in patients receiving 50 mg and 200 mg once daily (5x and 20x higher than the recommended dosage of 10 mg once daily). Perform baseline clinical and laboratory testing when starting LIVDELZI and monitor thereafter according to routine patient management. Interrupt treatment if the liver tests (ALT, AST, total bilirubin, and/or ALP) worsen, or if the patient develops signs and symptoms of clinical hepatitis (eg, jaundice, right upper quadrant pain, eosinophilia). Consider permanent discontinuation if liver tests worsen after restarting LIVDELZI. Biliary Obstruction: Avoid use of LIVDELZI in patients with complete biliary obstruction. If biliary obstruction is suspected, interrupt LIVDELZI and treat as clinically indicated. Adverse Reactions The most common adverse reactions (≥5%) with LIVDELZI were headache (8%), abdominal pain (7%), nausea (6%), abdominal distension (6%), and dizziness (5%). Drug Interactions OAT3 Inhibitors and Strong CYP2C9 Inhibitors: Avoid coadministration with LIVDELZI due to increased LIVDELZI exposure. Rifampin: Monitor biochemical response (e.g., ALP and bilirubin) when patients initiate rifampin during LIVDELZI treatment. Coadministration may result in delayed or suboptimal biochemical response of LIVDELZI. Dual Moderate CYP2C9 and Moderate-to-Strong CYP3A4 Inhibitors and BCRP Inhibitors (eg, cyclosporine): Monitor closely for adverse effects. Concomitant administration with LIVDELZI may increase LIVDELZI exposure. CYP2C9 Poor Metabolizers Using Moderate-to-Strong CYP3A4 Inhibitors: Monitor more frequently for adverse reactions as concomitant use of a moderate-to-strong CYP3A4 inhibitor in patients who are CYP2C9 poor metabolizers may increase LIVDELZI exposure and risk of LIVDELZI adverse reactions. Bile Acid Sequestrants: Administer LIVDELZI at least 4 hours before or 4 hours after taking a bile acid sequestrant, or at as great an interval as possible. Pregnancy and Lactation Pregnancy: There are insufficient data from human pregnancies exposed to LIVDELZI to allow an assessment of a drug-associated risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes. Report pregnancies to Gilead Sciences, Inc., at 1-800-445-3235. Lactation: There are no data on the presence of LIVDELZI in human milk, the effects on the breastfed infant, or the effects on milk production.

About PBC PBC is a rare, chronic inflammatory liver disease primarily affecting women (1 in 1,000 women over the age of 40 or about 130,000 total people in the U.S.). PBC is characterized by impaired bile flow (known as cholestasis) and the accumulation of toxic bile acids in the liver, leading to inflammation and destruction of the bile ducts within the liver and causing increased levels of alkaline phosphatase (ALP), alanine transaminase (ALT) and gamma-glutamyl transferase (GGT), enzymes found primarily in the liver, as well as total bilirubin. The most common symptoms of PBC are pruritus and fatigue, which can be debilitating for some people. Progression of PBC is associated with an increased risk of liver-related mortality.
