Criteria
Inclusion Criteria:- Male or female between the ages of 12 months and 18 years inclusive.
- Diagnosis of ALGS.
- Evidence of cholestasis (one or more of the following):
1. Total serum bile acid > 3x ULN for age.
2. Conjugated bilirubin > 1 mg/dL.
3. Fat soluble vitamin deficiency otherwise unexplainable.
4. GGT > 3x ULN for age.
5. Intractable pruritus explainable only by liver disease.
- Females of childbearing potential must have a negative serum pregnancy test during
Screening.
- Males and females of child-bearing potential who are sexually active, or are not
currently sexually active during the study, but become sexually active during the
period of the study and 30 days following the last dose of study drug, must agree and
use acceptable contraception during the trial.
- Participant is expected to have a consistent caregiver(s) for the duration of the
study.
- Informed consent and assent (per IRB/IEC) as appropriate.
- Access to phone for scheduled calls from study site.
- Caregivers (and age-appropriate participants) must be willing and able to use an
eDiary device during the study.
- Caregivers (and age-appropriate participants) must digitally accept the licensing
agreement in the eDiary software.
- Caregivers (and age-appropriate participants) must complete at least 10 eDiary reports
(morning or evening) during each of two consecutive weeks of the screening period
(maximum possible reports = 14 per week).
- Average daily score >2 on the Itch Reported Outcome (ItchRO™) questionnaire (maximum
possible daily score of 4) for two consecutive weeks in the screening period, prior to
dosing. A daily score is the higher of the scores for the morning and evening ItchRO.
The average daily score is the sum of all daily scores divided by the number of days
the ItchRO was completed.
Inclusion Criteria for participants to be eligible for the 52-week optional follow-up
treatment period:
- Completed the protocol through the Week 48 visit with no safety concerns. Participants
who were discontinued due to safety reasons can be rechallenged if blood tests are
back to relatively normal values for this patient population and participant does not
meet any of the protocol's stopping rules. The decision will be made by the
investigator in consultation with the sponsor medical monitor.
- Participants who have undergone a surgical disruption of the enterohepatic circulation
will not be eligible to enter into the follow up treatment period.
- Participants who were discontinued for other reasons will be considered for the
52-week optional follow-up treatment period on an individual basis. The decision will
be made by the investigator in consultation with the sponsor medical monitor.
Inclusion Criteria for participants with LUM001dosing interruption <7 days, or >=7 days:
- The Participant has either: completed the protocol through the Week 48 visit with no
major safety concerns OR discontinued due to safety reasons judged unrelated to the
study drug, and laboratory results have returned to levels acceptable for this patient
population or individual and participant does not meet any of the protocol's stopping
rules at the time of entry into the follow-up period. The decision will be made by the
investigator in consultation with the sponsor medical monitor. [Participants who were
discontinued for other reasons will be considered on an individual basis.]
- Females of childbearing potential must have a negative urine or serum pregnancy test
(beta- human chorionic gonadotropin [β-hCG]) at the time of entry into the long-term
optional follow-up treatment period.
- Males and females of child-bearing potential who are sexually active, or are not
currently sexually active during the study, but become sexually active during the
period of the study and 30 days following the last dose of study drug, must agree and
use acceptable contraception during the trial.
- Informed consent and assent (per IRB/EC) as appropriate.
- Access to phone for scheduled calls from study site.
- Caregivers (and age-appropriate participants) must be willing and able to use an
eDiary device during the study.
Exclusion Criteria:
- Chronic diarrhea requiring ongoing intravenous fluid or nutritional intervention.
- Surgical interruption of the enterohepatic circulation.
- Previous liver transplant
- Decompensated cirrhosis (ALT >15 x ULN, INR >1.5 [unresponsive to vitamin K therapy],
albumin <3.0 g/dL, history or presence of clinically significant ascites, variceal
hemorrhage, and/or encephalopathy).
- History or presence of other concomitant liver disease.
- History or presence of any other disease or condition known to interfere with the
absorption, distribution, metabolism or excretion of drugs, including bile salt
metabolism in the intestine (eg, inflammatory bowel disease).

- Known diagnosis of human immunodeficiency virus (HIV) infection.
- Cancers, except for in situ carcinoma, or cancers treated at least 5 years prior to
Screening with no evidence of recurrence.

unable to complete the study.

- Administration of bile acid or lipid binding resins within 28 days prior to screening
and throughout the trial.

- Receipt of investigational drug, biologic, or medical device within 28 days prior to
screening, or 5 half-lives of the study agent, whichever is longer.
- History of non-adherence to medical regimens, unreliability, mental instability or
incompetence that could compromise the validity of informed consent or lead to
nonadherence with the study protocol based upon investigator judgment.
- Any other conditions or abnormalities which, in the opinion of the investigator or
sponsor medical monitor, may compromise the safety of the participant, or interfere
with the participant participating in or completing the study.
- Participants weighing over 50 kg at screening.
