E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
In patients with progressive familial intrahepatic cholestasis (PFIC), impairment of the egress of bile acids from the liver leads to cholestasis, hepatocellular injury and damage, and progressive liver disease that may ultimately lead to the need for liver transplantation. Itch is a common symptom associated with cholestasis, it can occur at all stages of cholestatic liver disease, with or without jaundice.

due to liver and heart problems. |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The objectives of this study are:
To evaluate the safety and tolerability of LUM001 in paediatric subjects with PFIC
To evaluate the effect of LUM001 on serum bile acids associated with PFIC at 13 weeks of treatment
To evaluate the effect of LUM001 on biochemical markers of cholestasis and liver disease at 13 weeks of treatment
To evaluate the effect of LUM001 on pruritus associated with PFIC at 13 weeks of treatment
To evaluate the safety and long-term durability of effect of LUM001 in patients during 48-weeks of treatment |
|
E.2.2 | Secondary objectives of the trial |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
To participate in this study subjects must meet the following criteria:
1. Male or female subjects between the ages of 12 months and 18 years, inclusive
3. Diagnosis of PFIC based on:
a. 2. Intrahepatic cholestasis manifest by fasting total serum bile acid >100 micromol/L and b or c
b.Two documented mutant alleles in ATP8B1, or ABCB11, or other genes confirmed to cause PFIC
or
b. Evidence of chronic liver disease, excluding those listed in Protocol Appendix 16.3 with one or more of the following criteria:
i. Duration of biochemical or clinical abnormalities of >6 months, or
ii. Pathologic evidence of progressive liver disease, or
iii. Sibling of known individual affected by PFIC (predicted to be chronic)
4. GGTP <100 IU/L at screening
5. Females of childbearing potential must have a negative urine or serum pregnancy test [β human chorionic gonadotropin (β-hCG)] during screening and a negative urine pregnancy test at the baseline visit.
6. Sexually active females must be prepared to use an effective method (≤ 1% failure rate) of contraception during the trial. Effective methods of contraception are considered to be:
a. Hormonal (e.g., contraceptive pill, patch, intramuscular implant or
injection); or
b. Barrier method, e.g., (a) condom (male or female) or (b) diaphragm, with spermicide; or
c. Intrauterine device (IUD)
7. Informed consent and assent.
8. Access to phone for scheduled calls from study site.
9. The ability to read and understand English (caregivers and children above the age of assent).
10. Subjects expected to have a consistent caregiver(s) for the duration of the first 13 weeks of the study
11. Caregivers (and age appropriate subjects) must be willing and able to use an eDiary device as required by the study. To accommodate potential cultural restrictions within the FIC1 affected population a paper version of the ItchRO diary will be made available.
12. Caregivers (and age appropriate subjects) using the eDiary must digitally accept the licensing agreement in the eDiary software at the outset of the study.
13. Caregivers (and age appropriate subjects) must complete at least 10 eDiary reports (morning or evening) during each of two consecutive weeks of the screening period, prior to assignment (maximum possible reports = 14 per week). Subjects using a paper diary must complete the same number of reports within the same timeframe. |
|
E.4 | Principal exclusion criteria |
Subjects will be excluded from the study if they meet any of the following criteria:
1. Chronic diarrhoea requiring specific intravenous fluid or nutritional intervention for the diarrhoea and/or its sequelae.
2. Surgical disruption of the enterohepatic circulation.
3. Liver transplant
4. Decompensated liver disease [international normalized ratio (INR) > 1.5, albumin <30 g/L, history or presence of clinically significant ascites, variceal haemorrhage and/or encephalopathy].
5. ALT > 15 x ULN at screening.
6. History or presence of other liver disease (see Protocol Appendix 16.3).
7. 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 (e.g., inflammatory bowel disease).
8. Liver mass on imaging.
9. Known diagnosis of human immunodeficiency virus (HIV) infection.
10. Cancers except for in situ carcinoma, or cancers treated at least 5 years prior to screening with no evidence of recurrence.
11. Any female who is pregnant or lactating or who is planning to become pregnant within 20 weeks of assignment.
12. Any known history of alcohol or substance abuse.
13. Administration of bile acid or lipid binding resins within 30 days prior to assignment and throughout the trial.
14. Investigational drug, biologic, or medical device within 30 days prior to screening, or 5 half-lives of the study agent, whichever is longer.
15. History of non-adherence to medical regimens, unreliability, mental instability or incompetence that could compromise the validity of informed consent or lead to non-adherence with the study protocol based on Investigator judgment.
16. Any other conditions or abnormalities which, in the opinion of the Investigator or Medical Monitor, may compromise the safety of the subject, or interfere with the subject participating in or completing the study. |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary efficacy endpoint is change from baseline to Week 13 in serum bile acids.
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Day: 0, 14, 28, 56 and 91. |
|
E.5.2 | Secondary end point(s) |
Secondary efficacy endpoints include change from baseline to Week 13 in biochemical markers of cholestasis and liver disease (ALP, AST, ALT, total and direct bilirubin) and change from baseline to Week 13 in pruritus as measured by the average daily score of the ItchRO instrument.
The safety and long-term durability of effect of LUM001 in patients
will be assessed during 48-weeks of treatment. |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
Continuous variables will be summarized using descriptive statistics including n, mean, median, standard deviation, range (e.g., minimum and maximum). Qualitative variables will be summarized using counts and percentages. Summaries will be provided by study phase (Weeks 0-13 and 14-48) and over the entire study duration (Weeks 0-48), by visit and by stable dosing dose group (if appropriate). All data will be reported in data listings. Where appropriate, statistical tests will be conducted at the 0.05 significance level using two-tailed tests and p-values will be reported. Given the rare nature of PFIC, the statistical power of any comparisons is limited. As such the analysis will be largely descriptive in nature. |
