9. Twelve-lead ECG demonstrating QTc >460 milliseconds for male subjects or >470 milliseconds for female subjects at screening. If QTc exceeds 460 milliseconds for males or 470 milliseconds for females, the ECG should be repeated 2 more times and the average of the 3 QTc values should be used to determine the subject's eligibility

10. A positive screen for drugs of abuse at screening or at Day -3 (check-in).

11. Male subjects who consume more than 21 units of alcohol per week or 3 units per day. Female subjects who consume more than 14 units of alcohol per week or 2 units per day. (1 alcohol unit=1 beer or 1 wine [5 oz/150 mL] or 1 liquor [1.5 oz/40 mL] or 0.75 oz alcohol).

12. A positive HIV, hepatitis B surface antigen (HBsAg), or hepatitis C virus (HCV) antibody screen.

13. Use of tobacco (eg, smoking or chewing) or other nicotine-containing products (eg, gum, patch) in any form. Ex-users must report that they have stopped using tobacco for at least 30 days prior to receiving the first dose of investigational product.

14. Routine consumption of more than 2 units of caffeine per day or subjects who experience caffeine withdrawal headaches. (One caffeine unit is contained in the following items: one 6 oz [180 mL] cup of coffee, two 12 oz [360 mL] cans of cola, one 12 oz cup of tea, and three 1 oz [85 g] chocolate bars. Decaffeinated coffee, tea, and cola are not considered to contain caffeine.)

15. Prior screen failure, randomization, participation, or enrollment in this study. If a subject has successfully completed a study using LUM001 or SHP626, they may participate in this study providing at least 30 days has passed since their last dose of these investigational products and they have successfully completed all screening procedures

16. Current use of any medication (including over-the-counter, herbal, or homeopathic preparations) with the exception of those medications listed in Section 5.2.1. (Current use is defined as use within 14 days of the first dose of investigational product.)

17. An inability to follow a standardized diet and meal schedule or inability to fast, as required during the study.

18. Colonoscopy, barium enema, or other tests that require a bowel cleansing within 4 weeks prior to the first dose of investigational product.

19. Subjects who report typically having less than 3 bowel movements per week or greater than 3 bowel movements per day.

20. Use of antibiotics within 30 days prior to the first dose of investigational product.

21. Use of bile acid sequestrants within 30 days prior to the first dose of investigational product

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change From Baseline of Fecal Bile Acid Excretion After Dosing (Day 6 and Day 7)	Fecal bile acid excretion was determined by the concentration of total bile acids in stool samples over each 24-hour collection window during the lead-in and treatment periods.	Baseline, Day 7
Secondary	Number of Participants With Treatment Emergent Adverse Events (TEAEs)	An adverse event is defined as any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. An AE (classified by preferred term) that occurred during the treatment period was considered a TEAE if it had a start date on or after the first dose of IMP; it had a start date before the date of the first dose of IMP, but increased in severity on or after the date of the first dose of the blinded IMP.	Baseline up to follow-up (up to 16 days)
Secondary	Change From Baseline in Vital Signs (Supine Pulse Rate and Standing Pulse Rate) at Day 8 / End of Treatment (ET)	Supine Pulse Rate and Standing Pulse Rate were reported.	Baseline, Day 8
Secondary	Change From Baseline in Vital Signs (Blood Pressure) at Day 8 / End of Treatment (EOT)	Supine Systolic Blood Pressure (Supine SBP); Standing Systolic Blood Pressure (Standing SBP); Supine Diastolic Blood Pressure (Supine DBP); Standing Diastolic Blood Pressure (Standing DBP) were reported.	Baseline, Day 8
Secondary	Change From Baseline in 12-lead Electrocardiogram (ECG) - Heart Rate at Day 8 / End of Treatment (EOT)	Twelve-lead ECG was performed.	Baseline, Day 8
Secondary	Change From Baseline in 12-lead ECG Intervals at Day 8	Twelve-lead ECG was performed. The corrected QT interval (QTc) was derived by Bazett formula (QTcB=QT/(RR)^1/2) and Fridericia formula (QTcF=QT/(RR)^1/3). PR Interval; QRS Interval; QT Interval; QTcB Interval; QTcF Interval, RR Intervals were reported.	Baseline, Day 8
Secondary	Number of Participants with Clinically Meaningful Changes in Serum Biochemistry Laboratory Parameters	Number of participants with clinically meaningful changes in serum biochemistry laboratory parameters were reported.	Baseline up to Day 8
Secondary	Number of Participants with Clinically Meaningful Changes in Coagulation and Hematology Parameters	Activated partial thromboplastin time (aPTT), hematocrit, hemoglobin, monocytes and erythrocytes were analyzed. Number of participants with clinically meaningful change in coagulation and hematology parameters were reported.	Baseline up to Day 8
Secondary	Number of Participants With Clinically Meaningful Changes in Urinalysis Parameters	Number of participants with clinically meaningful changes in urinalysis parameters were reported.	Baseline up to Day 8
Secondary	Change From Baseline in Total Serum Bile Acid Concentration at Day 7	Serum bile acid concentrations were determined using a validated liquid chromatography with tandem mass spectrometric detection (LC/MS/MS) method.	Baseline, Day 7
Secondary	Change From Baseline in Serum Concentration of 7- alpha-hydroxy-4-cholesten-3-one (C4) at Day 7	Serum samples were assayed for C4 using a validated LC/MS/MS method.	Baseline, Day 7
Secondary	Stool Hardness Measured by Bristol Stool Chart at Day 7	Stool hardness was assessed according to the Bristol Stool Chart, where 1 was the hardest and 7 was the softest form of stool. Types 3 and 4 were considered normal and types at either end of the scale were considered severe.	Day 7
Secondary	Frequency of Bowel Movements at Day 7	Frequency of bowel movements were calculated by treatment group and by day.	Day 7
