Always SAFETY First!

>6 Years of Clinical Data
Plus Real-World Use1-3

Backed by >5 years of safety data,* LIVMARLI has a well-characterized safety and tolerability profile for cholestatic pruritus in patients with Alagille syndrome.1,2 In the ICONIC study, there were no discontinuations of LIVMARLI due to ineffectiveness.4

*The majority of exposure occurred without a placebo control in open-label extensions.

Terms were defined as: FSV deficiency includes vitamins A, D, E, and/or K deficiency, or International Normalized Ratio (INR) increase; abdominal pain includes abdominal discomfort, abdominal distension, abdominal pain, abdominal pain lower, abdominal pain upper; transaminases increased includes ALT abnormal, ALT increased, AST abnormal, AST increased; bone fractures include tibia fracture, rib fracture, humerus fracture, pathogical fracture, forearm fracture, and clavicle fracture.1

Additional Safety for LIVMARLI

The most common adverse reactions seen with LIVMARLI in the Alagille syndrome clinical development program, which included 5 clinical studies comprising 86 patients, were diarrhea, abdominal pain, vomiting, FSV deficiency, liver test abnormalities, and bone fractures.1

Five patients experienced treatment interruptions or dose reductions due to diarrhea, abdominal pain, or vomiting.1,5 Among those taking LIVMARLI, no patients discontinued due to diarrhea, abdominal pain, or vomiting.6

In a pooled analysis of patients with Alagille syndrome (n=86), 7 patients discontinued LIVMARLI due to increases in hepatic transaminases (alanine aminotransferase [ALT]) and 3 patients had a decrease in dose or interruption of LIVMARLI in response to these increases; elevations in transaminases were asymptomatic and not associated with bilirubin or other laboratory abnormalities.1

  • In the majority of cases, the elevations resolved or improved after discontinuation or dose modification of LIVMARLI1
  • In some cases, the elevations resolved or improved without change in LIVMARLI dosing1
  • Four patients experienced bilirubin increases above baseline, and LIVMARLI was subsequently withdrawn in 2 of these patients (those who had elevated bilirubin at baseline)1

Patients with Alagille syndrome can have FSV deficiency (vitamins A, D, E, and/or K) at baseline.1

  • LIVMARLI may affect absorption of FSV1

Pediatric patients aged 3 months to <12 months had similar safety, tolerability, and pharmacokinetic profiles to those ≥1 year old.1

Important Safety Information


LIVMARLI is contraindicated in patients with prior or active hepatic decompensation events (eg, variceal hemorrhage, ascites, or hepatic encephalopathy).

Warnings and Precautions

Hepatotoxicity: LIVMARLI treatment is associated with a potential for drug-induced liver injury. In the Alagille syndrome trial, treatment-emergent elevations of liver tests or worsening of liver tests occurred.

Obtain baseline liver tests and monitor during treatment. Liver-related adverse reactions and physical signs of hepatic decompensation should also be monitored. Dose reduction or treatment interruption may be considered if abnormalities occur in the absence of other causes. For persistent or recurrent liver test abnormalities, consider treatment discontinuation. Permanently discontinue LIVMARLI if a patient experiences the following: persistent or recurrent liver test abnormalities, clinical hepatitis upon rechallenge, or a hepatic decompensation event.

Gastrointestinal (GI) Adverse Reactions: Diarrhea and abdominal pain were reported as the most common adverse reactions. Monitor for dehydration and treat promptly. Consider reducing the dosage or interrupting dosing if a patient experiences persistent diarrhea or has diarrhea with bloody stool, vomiting, dehydration requiring treatment, or fever.

Fat-Soluble Vitamin Deficiency: Patients can have fat-soluble vitamin (FSV) deficiency (vitamins A, D, E, and K) at baseline, and LIVMARLI may adversely affect absorption of FSV. If bone fractures or bleeding occur, consider interrupting LIVMARLI and supplement with FSVs. LIVMARLI can be restarted once FSV deficiency is corrected and maintained at corrected levels.

Adverse Reactions

The most common adverse reactions are diarrhea, abdominal pain, vomiting, FSV deficiency, liver test abnormalities, and bone fractures.

Drug Interactions

Administer bile acid binding resins at least 4 hours before or 4 hours after administration of LIVMARLI. A decrease in the absorption of OATP2B1 substrates (eg, statins) due to OATP2B1 inhibition by LIVMARLI in the GI tract cannot be ruled out. Consider monitoring the drug effects of OATP2B1 substrates as needed.

Dosing Information

LIVMARLI should be taken 30 minutes before a meal. The provided oral dosing dispenser must be used to accurately measure the dose. Any remaining LIVMARLI should be discarded 100 days after first opening the bottle.
