FDA Grants Accelerated Approval to Iqirvo (elafibranor) for the Treatment of Primary Biliary Cholangitis

Ipsen (Euronext: IPN; ADR: IPSEY) today announced that the U.S. Food and Drug Administration (FDA) has granted accelerated approval for Iqirvo (elafibranor) 80 mg tablets 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. Iqirvo may be prescribed immediately in the U.S. for eligible patients.

This indication is approved under accelerated approval based on the reduction of alkaline phosphatase (ALP). Improvement in survival or prevention of liver decompensation events has not been demonstrated. Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trial(s). Iqirvo is not recommended for people who have or develop decompensated cirrhosis (e.g., ascites, variceal bleeding, hepatic encephalopathy).

“For a significant number of people living with PBC, available treatments do not control the condition and may exacerbate symptoms of PBC. Left unmanaged, PBC can progress, leading to liver failure and in some cases, the need for a liver transplant,” said Christelle Huguet, Executive Vice President, Head of Research and Development at Ipsen. “Iqirvo demonstrated statistically significant improvements in biochemical response compared to UDCA alone. Iqirvo is, therefore a much-needed treatment option and the first new medicine for PBC in nearly a decade.”

Iqirvo is a first-in-class oral, once-daily peroxisome proliferator-activated receptor (PPAR) agonist. Iqirvo was in-licensed from GENFIT in 2021. The accelerated approval of Iqirvo is based on data from the Phase III ELATIVE trial published in the New England Journal of Medicine1. The ELATIVE trial demonstrated that 13 times more patients achieved the composite primary endpoint of biochemical response when treated with Iqirvo plus UDCA (n=108) versus placebo plus UDCA (=53) (respectively 51% versus 4% for a 47% treatment difference). ALP is a biochemical marker and is used as a surrogate endpoint in PBC trials. Secondary endpoints showed normalization in ALP levels in only Iqirvo-treated patients (15% for Iqirvo plus UDCA (n=108) versus 0% for placebo plus UDCA (n=53)). Most patients (95%) received study treatment (Iqirvo or placebo) in combination with UDCA.

The most common adverse reactions with Iqirvo reported in ≥10% of study participants were weight gain, abdominal pain, diarrhea, nausea, and vomiting. Some study participants treated with Iqirvo experienced myalgia, myopathy and rhabdomyolysis; fractures; adverse effects on fetal and newborn development; drug-induced liver injury; hypersensitivity reactions; or biliary obstruction. See full Important Safety Information below.

“Data from the pivotal Phase III ELATIVE clinical trial demonstrated that Iqirvo is an effective second-line treatment for patients with PBC with favorable benefit and risk data,” said Dr. Kris Kowdley, Director at Liver Institute Northwest, Washington, and a primary investigator on the ELATIVE study. “The approval of Iqirvo will allow healthcare providers in the U.S. to address an unmet need with the potential to significantly reduce ALP levels for our patients with PBC.”

PBC 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.2, the majority being women, PBC is a lifelong condition that can worsen over time if not effectively treated, leading to liver transplant and in some cases, premature death. PBC also affects day-to-day life, with people most commonly experiencing severe fatigue symptoms and debilitating itch (pruritus).

“People living with PBC can feel like the symptoms they experience are dismissed by family members, friends, or even their doctors because they have not experienced something similarly disruptive in their lives. People with PBC may also feel uncertainty around the disease progression and if, or when, their liver health may deteriorate,” said Carol Roberts, Executive President of PBCers, a patient advocacy organization in the U.S. providing support to people living with PBC. “Earlier diagnosis and education about PBC, along with new treatment options are important to meet the current needs of people living with PBC.”

Iqirvo has been submitted to the European Medicines Agency (EMA) and the UK Medicines and Healthcare Products Regulatory Agency (MHRA), seeking authorization for PBC, with final EMA and MHRA regulatory decisions anticipated in the second half of 2024. The FDA approval of Iqirvo further strengthens Ipsen’s portfolio of treatments for rare cholestatic liver diseases available to patients in the U.S. This includes our FDA-approved medicine for the treatment of pruritus in patients three months and older with progressive familial intrahepatic cholestasis (PFIC) and for the treatment of cholestatic pruritus in patients from 12 months of age with Alagille syndrome (ALGS).

FDA Grants Accelerated Approval for Rezdiffra (resmetirom) for the Treatment of Patients with Noncirrhotic Nonalcoholic Steatohepatitis (NASH)

Madrigal Pharmaceuticals, Inc. (NASDAQ:MDGL), a biopharmaceutical company focused on delivering novel therapeutics for nonalcoholic steatohepatitis (NASH),  announced the U.S. Food and Drug Administration (FDA)  accelerated approval for Rezdiffra (resmetirom) in conjunction with diet and exercise for the treatment of adults with noncirrhotic NASH with moderate to advanced liver fibrosis (consistent with stages F2 to F3 fibrosis). Continued approval for this indication may be contingent upon verification and description of clinical benefit in ongoing confirmatory trials.

Bill Sibold, Chief Executive Officer of Madrigal, stated, “NASH with moderate to advanced liver fibrosis is a serious and progressive liver disease that, until now, has not had an FDA-approved therapy. The accelerated approval of Rezdiffra is a culmination of more than 15 years of research from our founder Dr. Becky Taub and a small R&D team that took on one of the biggest challenges in drug development. This is a historic moment for the NASH field and represents the best of what our industry is capable of. We’re excited to deliver Rezdiffra to patients in need.”

Becky Taub, M.D., the Founder, Chief Medical Officer and President of Research & Development of Madrigal, stated, “Madrigal would like to thank the many patients who made the accelerated approval of Rezdiffra possible by participating in our clinical studies. We believe Rezdiffra will change the treatment paradigm for NASH with moderate to advanced liver fibrosis, giving physicians a liver-directed therapy to help improve fibrosis and resolve NASH before their patients progress to cirrhosis.”

Wayne Eskridge, Co-Founder and Chief Executive Officer of the Fatty Liver Foundation, stated, “This is a day of celebration for patients with NASH who have been waiting many years for the first approved therapy. I believe this approval milestone will bring new energy and momentum to the NASH community, accelerating our efforts to improve disease education, build care pathways, and expand investment in NASH research.”

Rezdiffra is a once-daily, oral THR-β agonist designed to target key underlying causes of NASH. The accelerated approval of Rezdiffra was based on results from the Phase 3 MAESTRO-NASH trial, which was recently published in the New England Journal of Medicine. MAESTRO-NASH is an ongoing pivotal, multicenter, randomized, double-blind, placebo-controlled trial that enrolled 1,759 patients with biopsy-confirmed NASH. Following 52 weeks of treatment, both 100 mg and 80 mg doses of Rezdiffra demonstrated statistically significant improvement compared to placebo on two primary endpoints: NASH resolution (including a reduction in the nonalcoholic fatty liver disease [NAFLD] activity score by ≥2 points) with no worsening of fibrosis, and an improvement in fibrosis by at least one stage with no worsening of the NAFLD activity score. Fibrosis improvement and NASH resolution were consistent regardless of age, gender, type 2 diabetes status, or fibrosis stage.

The Rezdiffra prescribing information does not include a liver biopsy requirement for diagnosis. The recommended dosage of Rezdiffra is based on actual body weight. For patients weighing <100 kg (220 lbs.), the recommended dosage is 80 mg orally once daily. For patients weighing ≥100 kg (220 lbs.), the recommended dosage is 100 mg orally once daily.

Stephen Harrison, M.D., Chairman for both Pinnacle Clinical Research and Summit Clinical Research, San Antonio, Texas, Visiting Professor of Hepatology, Oxford University, and lead Principal Investigator of the MAESTRO studies, commented, “The approval of the first medication for NASH is a true game-changer for healthcare providers, the research community and, most importantly, patients living with this serious liver condition. Based on the robust efficacy and safety data generated in two large Phase 3 MAESTRO studies, I believe Rezdiffra will become the foundational therapy for patients with NASH with moderate to advanced liver fibrosis.”

Dr. Harrison continued, “Importantly, we continue to study Rezdiffra to determine if the positive results observed in the MAESTRO studies will lead to reduced risk of progression to cirrhosis, liver failure, need for liver transplant and premature mortality.”

MAESTRO-NASH remains ongoing as an outcomes study designed to generate confirmatory data that, if positive, will help verify clinical benefit and may support full approval. A second ongoing outcomes trial is evaluating progression to liver decompensation events in patients with well-compensated NASH cirrhosis treated with Rezdiffra versus placebo.

Rezdiffra should not be used in patients with decompensated cirrhosis. The most common adverse reactions reported in patients treated with Rezdiffra included diarrhea, nausea, pruritis, abdominal pain, vomiting, constipation, and dizziness. Diarrhea and nausea typically began early in treatment initiation and were mild to moderate in severity. A separate, noninvasive Phase 3 trial, MAESTRO-NAFLD-1, evaluated the safety and tolerability of Rezdiffra and contributed to the safety database supporting regulatory benefit-risk assessment.

Rezdiffra is expected to be available to patients in the U.S. in April and will be distributed through a limited specialty pharmacy network. Madrigal is committed to helping appropriate patients who may benefit from Rezdiffra access the medication through the Madrigal Patient Support program. This program is designed to help patients navigate insurance and affordability challenges and provide co-pay support for eligible patients. Madrigal has also established a patient assistance program (PAP) to help patients with no insurance access Rezdiffra.

Phase 3 MAESTRO-NASH Trial Results

MAESTRO-NASH is an ongoing Phase 3 trial that enrolled 1759 patients with biopsy-confirmed NASH. Patients were randomly assigned in a 1:1:1 ratio to receive once-daily Rezdiffra at a dose of 80 mg or 100 mg or placebo. The two primary endpoints at week 52 were NASH resolution with no worsening of fibrosis and an improvement in fibrosis by at least one stage with no worsening of the NAFLD activity score. The key secondary endpoint was the percent change from baseline in LDL cholesterol at week 24.

Rezdiffra achieved both primary endpoints and the key secondary endpoint of the MAESTRO-NASH trial. Additionally, Rezdiffra improved liver enzymes, fibrosis biomarkers and imaging tests as compared with placebo. The primary results of the trial were published in the New England Journal of Medicine in February 2024.

Patients enrolled in the MAESTRO-NASH trial continue on therapy after the initial 52-week treatment period for up to 54 months to accrue and measure hepatic clinical outcome events including progression to cirrhosis on biopsy and hepatic decompensation events, as well as all-cause mortality. The 54-month outcomes portion of the trial is designed to generate confirmatory data that, if positive, will help verify Rezdiffra’s clinical benefit and may support full approval.

FDA Grants Accelerated Approval for Qalsody (tofersen) for the Treatment of Amyotrophic Lateral Sclerosis Associated with a Mutation in the SOD1 Gene

Biogen Inc. (Nasdaq: BIIB) announced the U.S. Food and Drug Administration (FDA)   approval of  Qalsody (tofersen) 100 mg/15mL injection for the treatment of amyotrophic lateral sclerosis (ALS) in adults who have a mutation in the superoxide dismutase 1 (SOD1) gene. This indication is approved under accelerated approval based on reduction in plasma neurofilament light chain (NfL) observed in patients treated with Qalsody. Continued approval for this indication may be contingent upon verification of clinical benefit in confirmatory trial(s).1 The ongoing Phase 3 ATLAS study of tofersen in people with presymptomatic SOD1-ALS will serve as the confirmatory trial.

Neurofilaments are proteins that are released from neurons when they are damaged, making them a marker of neurodegeneration.6

“For more than a decade, Biogen has been steadfast in our commitment to pursuing treatments for ALS, and I want to thank the scientists as well as the entire ALS community who have all worked tirelessly to bring this first-of-its-kind treatment to people with SOD1-ALS,” said Christopher A. Viehbacher, President and Chief Executive Officer of Biogen. “Today also marks a pivotal moment in ALS research as we gained, for the first time, consensus that neurofilament can be used as a surrogate marker reasonably likely to predict clinical benefit in SOD1-ALS. We believe this important scientific advancement will further accelerate innovative drug development for ALS.”

Qalsody is the first approved treatment to target a genetic cause of ALS. Biogen collaborated with Ionis Pharmaceuticals on the early development of tofersen.

Warnings and precautions associated with Qalsody were serious neurologic events, including myelitis and/or radiculitis; papilledema and elevated intracranial pressure; and aseptic meningitis. If symptoms consistent with myelitis, radiculitis papilledema, elevated intracranial, or aseptic meningitis develop, diagnostic workup and treatment should be initiated according to the standard of care. Management may require interruption or discontinuation of Qalsody. The most common adverse reactions that occurred in ≥10% of Qalsody treated participants and more than the placebo arm were pain, fatigue, arthralgia, cerebrospinal (CSF) white blood cell increased, and myalgia.

“Since SOD1 mutations were first identified as a cause of ALS 30 years ago, the familial ALS community has been searching for genetically targeted treatments. Qalsody offers families who have lost generation after generation in the prime of their life to this devastating disease a therapy targeting the underlying cause of SOD1-ALS. Today marks an important moment in ALS research as Qalsody is the first ALS treatment approved based on a biomarker,” said Jean Swidler, chair of Genetic ALS & FTD: End the Legacy. “We are excited to see what future therapies are developed now that it is understood that lowering levels of neurofilament provides important evidence that a treatment is affecting the neurodegenerative process.”

The efficacy of Qalsody was assessed in a 28-week randomized, double-blind, placebo-controlled clinical study in patients 23 to 78 years of age with weakness attributable to ALS and a SOD1 mutation confirmed by a central laboratory. One hundred eight (108) patients were randomized 2:1 to receive treatment with either Qalsody 100 mg (n=72) or placebo (n=36) for 24 weeks (3 loading doses followed by 5 maintenance doses). Concomitant riluzole and/or edaravone use was permitted for patients and at baseline 62% of patients were taking riluzone, and 8% of patients were taking edaravone.

Over 28 weeks in VALOR, participants in the primary analysis population (n=60) treated with Qalsody experienced less decline from baseline as measured by the Revised Amyotrophic Lateral Sclerosis Functional Rating Scale (ALSFRS-R) compared to placebo, though the results were not statistically significant (Qalsody-placebo adjusted mean difference [95% CI]: 1.2 [-3.2, 5.5]). In the overall intent-to-treat population (n=108), Qalsody-treated participants experienced a 55% reduction in plasma NfL compared to a 12% increase in placebo-treated participants (difference in geometric mean ratios for Qalsody to placebo: 60%; nominal p<0.0001). Additionally, levels of CSF SOD1 protein, an indirect measure of target engagement, were reduced by 35% in the Qalsody-treated group compared to 2% in the corresponding placebo group (difference in geometric mean ratios for Qalsody to placebo: 34%; nominal p<0.0001).
