An Extension Study to Evaluate the Long-Term Safety and Durability of Effect of LUM001 in the Treatment of Cholestatic Liver Disease in Subjects With Alagille Syndrome (ALGS) (IMAGINE)

November 17, 2021 updated by: Mirum Pharmaceuticals, Inc.

A Multicentre Extension Study to Evaluate the Long-Term Safety and Durability of the Therapeutic Effect of LUM001 Also Known as Maralixibat (MRX), an Apical Sodium-Dependent Bile Acid Transporter Inhibitor (ASBTi), in the Treatment of Cholestatic Liver Disease in Pediatric Subjects With Alagille Syndrome

The purpose of this extension study is to determine the long-term safety and tolerability of an investigational treatment (LUM001 also known as Maralixibat) in children with ALGS who have completed participation in a core LUM001 treatment protocol. Efficacy will be assessed by evaluating the effect of LUM001 on pruritus, biochemical markers of pruritus, as well as biochemical markers of cholestasis and liver disease.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

1 year to 18 years (Child, Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Participation for an individual patient is expected to be approximately 72 weeks.

Patients who complete 72 weeks of treatment may be eligible to receive treatment for up to 52 weeks during the follow-up treatment period and patients who completed the 124 weeks of treatment may be eligible to enter the additional long-term follow-up period.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change From MRX Baseline to Week 48 in Fasting sBA Levels
Time Frame: MRX baseline to Week 48
The primary endpoint of this study was the mean change from MRX baseline to Week 48 in fasting sBA level.
MRX baseline to Week 48

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change From MRX Baseline Over Time in Fasting sBA Levels
Time Frame: MRX baseline to End of Treatment (maximum exposure was 336 weeks)
This secondary efficacy endpoint is the mean change from MRX baseline over time in fasting sBA levels. Results reported here are the long-term results.
MRX baseline to End of Treatment (maximum exposure was 336 weeks)
Change From MRX Baseline to Week 48 in Pruritus
Time Frame: MRX baseline to Week 48
This secondary efficacy endpoint is the change from MRX baseline to Week 48 in pruritus as measured by ItchRO(Obs) weekly average morning severity score. ItchRO scores range from 0 to 4; the higher score indicates increasing itch severity (0 = none; 4 = very severe).
MRX baseline to Week 48
Change From MRX Baseline Over Time in Pruritus
Time Frame: MRX baseline to End of Treatment (maximum exposure was 336 weeks)
This secondary efficacy endpoint is the change from MRX baseline over time in pruritus as measured by ItchRO(Obs) weekly average morning severity score. ItchRO scores range from 0 to 4; the higher score indicates increasing itch severity (0 = none; 4 = very severe). Results reported here are the long-term results.

Change From MRX Baseline to Week 48 in Clinician Xanthoma Severity Score
Time Frame: MRX baseline to Week 48
This secondary efficacy endpoint is the mean change from MRX baseline to Week 48 in clinician xanthoma severity scores. It is based on a 0-4 scale to rate the number of lesions present and the degree to which the participant's lesions interfere or limit his or her activities. Clinician xanthoma severity scores range from 0 to 4, with a xanthoma score of zero representing no evidence of xanthomatosis and a score of 4 representing xanthoma so severe that it is disabling. Clinician xanthoma severity scores were not assessed in Study LUM001-302 so mean clinician xanthoma severity score at MRX baseline was calculated from the 5 participants who were assigned to placebo in Study LUM001-302, and analysis of change from MRX baseline is not presented.

Time Frame: MRX baseline to End of Treatment (maximum exposure was 336 weeks)
This secondary efficacy endpoint is the mean change from MRX baseline over time (with Week 252 chosen as the end point, as the last analysis visit with at least 6 participants) in clinician xanthoma severity scores. It is based on a 0-4 scale to rate the number of lesions present and the degree to which the lesions interfere or limit activities. Clinician xanthoma severity scores range from 0 to 4, with a score of zero representing no evidence of xanthomatosis and a score of 4 representing xanthoma so severe that it is disabling. Clinician xanthoma severity scores were not assessed in Study LUM001-302 so mean clinician xanthoma severity score at MRX baseline was calculated from the 5 participants assigned to placebo in Study LUM001-302, and analysis of change from MRX baseline is not presented.
