Proposal to list cholic acid (Cholebiol) for rare disorder

Medicines

Consultation Closed

PHARMAC is seeking feedback on a proposal to list cholic acid (Cholebiol) resulting from a provisional agreement formed between Max Health Limited and PHARMAC.

The provisional agreement is the fifth that PHARMAC has reached with a bidder in a Request for Proposals we ran in 2014, related to the supply of medicines for rare disorders.

In summary, this proposal would result in cholic acid (Cholebiol) being funded in the community under Special Authority criteria and in DHB hospitals subject to restrictions for the treatment of bile acid synthesis disorders due to single enzyme defects with neonatal/infant-onset liver disease.

Listing in the Pharmaceutical Schedule would occur after Medsafe approval of the pharmaceutical.

Background

Cholic acid is an oral treatment for inborn errors of primary bile acid synthesis in the liver that can lead to progressive liver disease and death. Inborn errors of bile acid synthesis are rare genetic disorders that can present as neonatal cholestasis, neurologic disease or fat-soluble-vitamin deficiencies. The clinical presentation of these disorders is variable. Severe forms usually present within the first year of life. Milder forms may present in older children or adults.

Cholic acid is one of the primary bile acids that would normally be produced by the body. It is considered that taking cholic acid orally can mitigate the effects of the disorder. The proposal is to list cholic acid with Special Authority criteria restricting funding to patients with bile acid synthesis disorders due to single enzyme defects with neonatal/infant onset liver disease.  Evidence suggests cholic acid would both extend life and improve quality of life.

PHARMAC estimates there would be up to 2 infants per year that would be eligible for cholic acid under the proposed indications.

To date, PHARMAC has not received any NPPA applications for the funding of cholic acid for individuals with a single enzyme deficiency resulting from an inborn error in primary bile acid synthesis. 

Various forms of cholic acid are approved in Europe and the United States. Max Health Limited intends to submit an application for registration of Cholebiol to Medsafe as soon as possible.

PHARMAC’s evaluation of Cholebiol followed the process described in Schedule 2 of the Request for Proposals (RFP) for the supply of medicines for rare disorders. The RFP document can be found on the PHARMAC website.
