Mirum Pharmaceuticals kondigt positief CHMP-advies aan voor LIVMARLI® (maralixibat) orale oplossing voor cholestatische pruritus bij patiënten met het Alagille-syndroom van twee maanden en ouder
– CHMP-advies gebaseerd op cruciale ICONIC-studie met meer dan vijf jaar aan gegevens die duurzame en klinisch betekenisvolle verbeteringen aantonen in cholestatische pruritus en serumgalzuren bij patiënten met het syndroom van Alagille (ALGS).
– Op aanbeveling van het CHMP wordt eind 2022 een besluit van de Europese Commissie verwacht; indien goedgekeurd, zou LIVMARLI het eerste medicijn zijn voor de behandeling van cholestatische pruritus voor patiënten met ALGS in Europa.
– LIVMARLI heeft ook goedkeuring gekregen van het Israëlische ministerie van Volksgezondheid voor cholestatische pruritus bij patiënten met het Alagille-syndroom van één jaar en ouder; vertegenwoordigt de tweede regelgevende goedkeuring in de indicatie en de eerste goedkeuring buiten de V.S.
FOSTER CITY, Californië–(BUSINESS WIRE)– Mirum Pharmaceuticals, Inc. (Nasdaq: MIRM) heeft vandaag twee wereldwijde verbeteringen aangekondigd voor LIVMARLI® (maralixibat) orale oplossing, een orale minimaal geabsorbeerde ileale galzuurtransporter (IBAT)-remmer die momenteel is goedgekeurd in de VS voor de behandeling van cholestatische pruritus bij patiënten met het Alagille-syndroom van één jaar en ouder.
Mirum Pharmaceuticals Announces Positive CHMP Opinion for LIVMARLI® (maralixibat) Oral Solution for Cholestatic Pruritus in Patients with Alagille Syndrome Two Months of Age and Older
– CHMP opinion based on pivotal ICONIC study with more than five years of data demonstrating durable and clinically meaningful improvements in cholestatic pruritus and serum bile acids for patients with Alagille syndrome (ALGS).
– Following CHMP recommendation, a decision by the European Commission is expected by year-end 2022; if approved, LIVMARLI would be the first medication to treat cholestatic pruritus for patients with ALGS in Europe.
– LIVMARLI also received approval by Israeli Ministry of Health for cholestatic pruritus in patients with Alagille syndrome one year of age and older; represents second regulatory approval in the indication and first approval outside of U.S.
FOSTER CITY, Calif.–(BUSINESS WIRE)– Mirum Pharmaceuticals, Inc. (Nasdaq: MIRM) today announced two global advancements for LIVMARLI® (maralixibat) oral solution, an oral minimally absorbed ileal bile acid transporter (IBAT) inhibitor currently approved in the U.S. for the treatment of cholestatic pruritus in patients with Alagille syndrome one year of age and older.
The European Committee for Medicinal Products for Human Use (CHMP) has adopted a positive opinion of LIVMARLI for the treatment of cholestatic pruritus in patients with Alagille syndrome (ALGS) two months of age and older. The CHMP positive opinion is the scientific recommendation to the European Commission for grant marketing authorization in Europe. LIVMARLI was previously approved by the U.S. Food and Drug Administration in 2021 as the first and only treatment for cholestatic pruritus in patients with ALGS one year of age and older.
Mirum also announced that its partner, Neopharm, received commercial and marketing authorization by the Israeli Ministry of Health, Israel’s regulatory agency responsible for the approval of new medicines, granting approval of LIVMARLI for the treatment of cholestatic pruritus in patients with ALGS one year of age and older.
“LIVMARLI is the first and only medicine to receive CHMP positive opinion to address cholestatic pruritus in patients with Alagille syndrome and we are hopeful that this medication provides a meaningful treatment option for people suffering from this devastating disease,” said Chris Peetz, president and chief executive officer at Mirum. “Our experience with LIVMARLI in the U.S. has shown the impact it can have on the lives of patients and their families living with ALGS. We are eagerly preparing for the launch of LIVMARLI in Europe and are excited about the opportunity to further expand LIVMARLI’s availability globally, which is off to a great start with the recent approval in Israel.”
ALGS is a rare genetic disease caused by abnormalities in bile ducts that can lead to progressive liver disease. Malformed or reduced bile ducts cause retention of bile acids in the liver leading to cholestasis and ultimately inflammation and liver injury which prevents the liver from working properly. Cholestasis in ALGS leads to a debilitating pruritus impacting the quality of life so significantly that pruritus is a leading indication for liver transplantation.
The positive CHMP opinion is based on data from the pivotal ICONIC study including five years of data across the LIVMARLI clinical program resulting in a robust body of evidence in patients with ALGS. Data from ICONIC demonstrated statistically significant and clinically meaningful reductions in pruritus compared to placebo with a mean difference of -1.4 points between groups, as well as significant reductions in serum bile acids, both of which were durably maintained over several years of treatment. The proposed label also includes reductions in xanthoma severity.
The European Commission’s endorsement of the CHMP positive opinion is expected in the fourth quarter of 2022. If approved in Europe, LIVMARLI would be the first and only approved treatment to address the effects of Alagille syndrome, a rare and devastating liver disease impacting 1 out of 30,000 people globally.
“The positive opinion adopted by the CHMP is an important step forward in the treatment of cholestatic pruritus for people living with Alagille syndrome, given the lack of treatments to effectively address this terrible disease burden which can ultimately lead to a decision for liver transplantation,” said Professor Emmanuel Jacquemin, MD, PhD, Head of Pediatric Hepatology and Liver Transplantation Unit, Bicêtre Hospital, AP-HP, Paris-Saclay University, Le Kremlin-Bicêtre, France. “We are excited about the potential approval and availability of LIVMARLI for patients in Europe.”
“Alagille syndrome is seen in patients globally. Outside the U.S. only limited treatment options have been available until now to effectively help people deal with the debilitating effects of the disease, especially pruritus. Pruritus causes significant disruptions to the lives of both patients and their family members,” said Roberta Smith, president of the Alagille Syndrome Alliance. “We are thrilled that there is hope on the near horizon for people with Alagille syndrome in Europe and are optimistic that LIVMARLI may provide relief to those suffering from cholestatic pruritus in ALGS if approved, much like we’ve heard from our U.S. families following LIVMARLI’s launch in the United States.”
About Alagille Syndrome
Alagille syndrome (ALGS) is a rare genetic disorder in which bile ducts are abnormally narrow, malformed and reduced in number, which leads to bile accumulation in the liver and ultimately progressive liver disease. The estimated incidence of ALGS is one in every 30,000 people.1 In patients with ALGS, multiple organ systems may be affected by the mutation, including the liver, heart, kidneys and central nervous system.2 The accumulation of bile acids prevents the liver from working properly to eliminate waste from the bloodstream and, according to recent reports, 60% to 75% of patients with ALGS have a liver transplant before reaching adulthood.3 Signs and symptoms arising from liver damage in ALGS may include jaundice (yellowing of the skin), xanthomas (disfiguring cholesterol deposits under the skin), and pruritus (itch)2. The pruritus experienced by patients with ALGS is among the most severe in any chronic liver disease and is present in most affected children by the third year of life.4

IMPORTANT SAFETY INFORMATION
LIVMARLI can cause side effects, including:
Changes in liver tests. Changes in certain liver tests are common in patients with Alagille syndrome and can worsen during treatment with LIVMARLI. These changes may be a sign of liver injury and can be serious. Your healthcare provider should do blood tests before starting and during treatment to check your liver function. Tell your healthcare provider right away if you get any signs or symptoms of liver problems, including nausea or vomiting, skin or the white part of the eye turns yellow, dark or brown urine, pain on the right side of the stomach (abdomen) or loss of appetite.
Stomach and intestinal (gastrointestinal) problems. LIVMARLI can cause stomach and intestinal problems, including diarrhea, stomach pain, and vomiting during treatment. Tell your healthcare provider right away if you have any of these symptoms more often or more severely than normal for you.
A condition called Fat Soluble Vitamin (FSV) Deficiency caused by low levels of certain vitamins (vitamin A, D, E, and K) stored in body fat. FSV deficiency is common in patients with Alagille syndrome but may worsen during treatment. Your healthcare provider should do blood tests before starting and during treatment.
Other common side effects reported during treatment were bone fractures and gastrointestinal bleeding.
