Health Condition(s) or Problem(s) studied

Therapeutic area: Body processes [G] - Metabolic Phenomena [G03]

Primary biliary cirrhosis (PBC) is a chronic and slowly progressive cholestatic liver disease of autoimmune etiology characterized by injury of the intrahepatic bile ducts that may eventually lead to liver failure. Affected individuals are usually in their fifth to seventh decades of life at time of diagnosis, and 90% are women.
MedDRA version: 16.1 Level: LLT Classification code 10036680 Term: Primary biliary cirrhosis System Organ Class: 100000004871

Intervention(s)

Product Name: LUM001
Pharmaceutical Form: Tablet
INN or Proposed INN: LUM001
Current Sponsor code: LUM001
Concentration unit: mg milligram(s)
Concentration type: range
Concentration number: 5-20
Pharmaceutical form of the placebo: Tablet
Route of administration of the placebo: Oral use

Primary Outcome(s)

Main Objective: The primary objective of this study in subjects with primary biliary cirrhosis (PBC) undergoing daily dosing over a 13-week period is:

To evaluate the effect of LUM001 in combination with ursodeoxycholic acid (UDCA) versus UDCA alone on the reduction of pruritus associated with PBC.

Secondary Objective: The secondary objectives of this study are:

To evaluate the effect of LUM001 in combination with UDCA versus UDCA alone on alkaline phosphatase levels associated with PBC.

To evaluate the effect of LUM001 in combination with UDCA versus UDCA alone on liver enzymes associated with PBC.

To evaluate the safety and tolerability of LUM001 in combination with UDCA during 13 weeks of therapy in patients with PBC.

The exploratory objectives of this study are:

To explore the effect of LUM001 in combination with UDCA versus UDCA alone on other biochemical markers associated with PBC.

To explore the effect of LUM001 in combination with UDCA versus UDCA alone on quality of life using a PBC-specific health related quality of life (PBC-40) instrument.

To explore the effect of LUM001 in combination with UDCA versus UDCA alone on sleep using the Medical Outcomes Study Sleep Scale (MOS-Sleep).

Primary end point(s): The primary efficacy endpoint is change from baseline to Week 13 in pruritus as measured by the weekly sum score using the Adult ItchRO instrument. For this instrument, the subject indicates the severity of their itching in the morning and in the evening each day during screening and during the study period for 13 weeks. The
daily score will be assessed as outlined in Section 8.4.1 of the protocol and will have a range from 0-10, with the higher score indicating increasing itch severity. The Adult ItchRO weekly sum score will be the sum of each daily score over a study week, and is thought to provide a
measure of the weekly burden of itch.

For the change from baseline calculation in the Adult ItchRO weekly sum score, baseline is defined as the weekly sum of the daily scores in the week consisting of the 7 days immediately prior to Day 0. The Week 13 Adult ItchRO weekly sum score is defined as the weekly sum of the daily scores of the week consisting of the 7 days immediately prior to the Week 13 visit. Missing data on the daily score will be imputed using the average daily Adult ItchRO score from that week.

Timepoint(s) of evaluation of this end point: Week 0 and week 13.

Secondary Outcome(s)

Secondary end point(s): Secondary efficacy endpoints include:

Change from baseline in pruritus as measured by Adult ItchRo weekly sum scores at Weeks 4 and 8.
?
Change from baseline in pruritis as measured by the AdultItchRO average daily scores at weeks 4, 8 and 13. The average daily score for a 7-day period will be the sum of the daily scores for the 7-day period divided by the number of days the dairy is completed in that 7-day period

Change from baseline in alkaline phosphatase at Weeks 4, 8 and 13.

Change from baseline in 5-D Itch score at Weeks 4, 8 and 13.

Change from baseline in fasting serum bile acid level at Weeks 4, 8 and 13.

Change from baseline for other liver enzymes (ALT, AST) at Weeks 4, 8 and 13.

Change from baseline for lipid biomarkers (total cholesterol, LDL-C) at Weeks 4 and 13.

Change from baseline for PBC-40 at Weeks 4, 8 and 13.

Change from baseline for MOS-Sleep at Weeks 4 and 13.

Patient Impression of Change (PIC) at Week 13.

Patient Global Therapeutic Benefit (PGTB) assessment at Week 13.

In addition, the following exploratory evaluations will be conducted if the results of the primary and secondary analyses illustrate a difference between drug and placebo treated subjects.

Change from baseline for measures of bile acid synthesis (FGF-19 and FGF-21) at Weeks 4 and 13.
