July 22, 2026 updated by: Albireo

Odevixibat (A4250) for the Treatment of Progressive Familial Intrahepatic Cholestasis (Expanded Access Program)

To provide treatment access to patients with PFIC in the US who have pruritus and elevated serum bile acids and who are not able to enroll in A4250-008 (PEDFIC2) for the following reasons: 1) Do not meet eligibility criteria for PEDFIC 2; 2) Are not able to get to a PEDFIC 2 site for geographical reasons, and 3) Do meet the eligibility criteria for PEDFIC 2 after recruitment has been completed

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
No longer available

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Eligible patients will be enrolled into this expanded-access program and treated with an oral dose of 120 μg/kg/day of odevixibat and evaluated on an ongoing basis.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Expanded Access

Expanded Access Type

Expanded Access Type

Describes the category of expanded access under U.S. Food and Drug Administration (FDA) regulations. There are three types of expanded access:
  • Individual Patients: Allows a single patient, with a serious disease or condition who cannot participate in a clinical trial, access to a drug or biological product that has not been approved by the FDA. This category also includes access in an emergency situation.
  • Intermediate-size Population: Allows more than one patient (but generally fewer patients than through a Treatment IND/Protocol) access to a drug or biological product that has not been approved by the FDA. This type of expanded access is used when multiple patients with the same disease or condition seek access to a specific drug or biological product that has not been approved by the FDA.
  • Treatment IND/Protocol: Allows a large, widespread population access to a drug or biological product that has not been approved by the FDA. This type of expanded access can only be provided if the product is already being developed for marketing for the same use as the expanded access use.
