Primary biliary cholangitis

Active Ingredient: Obeticholic acid

Indication for Obeticholic acid

Population group: only adults (18 years old or older)
Therapeutic intent: Curative procedure

Obeticholic acid is indicated for the treatment of primary biliary cholangitis (also known as primary biliary cirrhosis) in combination with ursodeoxycholic acid (UDCA) in adults with an inadequate response to UDCA or as monotherapy in adults unable to tolerate UDCA.

For this indication, competent medicine agencies globally authorize below treatments:

5 mg once daily for the first 6 months, thereafter 5-10 mg once daily

For:

Dosage regimens

Oral, 5 milligrams obeticholic acid, once daily, over the duration of 6 months. Afterwards, oral, between 5 milligrams obeticholic acid and 10 milligrams obeticholic acid, once daily.

Detailed description

Prior to initiation of treatment with obeticholic acid the patient’s hepatic status must be known. Whether the patient has decompensated cirrhosis (including Child-Pugh Class B or C) or has had a prior decompensation event should be determined prior to initiation of treatment because obeticholic acid is contraindicated in these patients.

The starting dose of obeticholic acid is 5 mg once daily for the first 6 months.

After the first 6 months, for patients who have not achieved an adequate reduction in alkaline phosphatase (ALP) and/or total bilirubin and who are tolerating obeticholic acid, increase to a maximum dose of 10 mg once daily.

No dose adjustment of concomitant UDCA is required in patients receiving obeticholic acid.

Management and dose adjustment for severe pruritus

Management strategies include the addition of bile acid binding resins or antihistamines.

For patients experiencing severe intolerability due to pruritus, one or more of the following should be considered:

  • The dose of obeticholic acid may be reduced to:
    • 5 mg every other day, for patients intolerant to 5 mg once daily
    • 5 mg once daily, for patients intolerant to 10 mg once daily
  • The dose of obeticholic acid may be temporarily interrupted for up to 2 weeks followed by restarting at a reduced dose.
  • The dose may be increased to 10 mg once daily, as tolerated, to achieve optimal response.

Discontinuing treatment with obeticholic acid may be considered for patients who continue to experience persistent, intolerable pruritus.

Bile acid binding resins

For patients taking bile acid binding resins, obeticholic acid should be administered at least 4 to 6 hours before or 4 to 6 hours after taking a bile acid binding resin, or at as great an interval as possible.

Missed dose

If a dose is missed, the missed dose should be skipped and the normal schedule should be resumed for the following dose. A double dose should not be taken to make up for the missed dose.

Dosage considerations

It should be taken orally with or without food.

Active ingredient

Obeticholic acid

Obeticholic acid is a selective and potent agonist for the farnesoid X receptor (FXR), a nuclear receptor expressed at high levels in the liver and intestine. FXR activation decreases the intracellular hepatocyte concentrations of bile acids by suppressing de novo synthesis from cholesterol, as well as, by increasing transport of bile acids out of the hepatocytes.
