NCT02654002

Brief Summary

This study will evaluate the safety and tolerability of escalating single- and multiple-oral doses of cilofexor, and characterize the single- and multiple-dose pharmacokinetics (PK) of cilofexor. The study will be conducted in 3 parts (Part A, Part B, and Part C). Participants will receive either cilofexor or cilofexor placebo. Part A will proceed in 4 prespecified staggered cohorts. Within each cohort, the cumulative, blinded safety data will be evaluated for dose escalation from single-dose (Period 1) to multiple-dose (Period 2). Based on the available safety, pharmacokinetics, and/or pharmacodynamics (PD) data from cohorts in Part A and Part C (if applicable), total daily doses and frequency of dosing will be chosen for the cohorts in Part B. Parts B and C will consist of adaptive cohorts and may be initiated in parallel. Part B cohorts may be initiated in parallel with cohorts in Part A if the total dose under evaluation is at or below a dose already evaluated. This study is partially blinded (no one is blinded on Day -1).

Outcome Measures

Primary Outcomes (9)

  • Single-Dose Pharmacokinetic (PK) Parameter: AUClast of Cilofexor

    AUClast is defined as the concentration of drug from time zero to the last quantifiable concentration.

    Day 1: -0.5, 0 (pre-dose), 0.25, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 8, 10, 12, 16, 24, 48, 72, and 96 hours post-dose

  • Single-Dose PK Parameter: AUCinf of Cilofexor

    AUCinf is defined as the concentration of drug extrapolated to infinite time (area under the plasma concentration versus time curve extrapolated to infinite time).

    Day 1: -0.5, 0 (pre-dose), 0.25, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 8, 10, 12, 16, 24, 48, 72, and 96 hours post-dose

  • Single-Dose PK Parameter: Cmax of Cilofexor

    Cmax is defined as the maximum observed concentration of drug in plasma.

    Day 1: -0.5, 0 (pre-dose), 0.25, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 8, 10, 12, 16, 24, 48, 72, and 96 hours post-dose

  • Multiple-Dose PK Parameter: AUCtau of Cilofexor

    AUCtau is the concentration of drug over time (area under the plasma concentration versus time curve over the dosing interval).

    Day 20: -0.5, 0 (pre-dose), 0.25, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 8, 10, 12, 16, 24, 48, 72, and 96 hours post-dose

  • Multiple-Dose PK Parameter: Cmax of Cilofexor

    Cmax is defined as the maximum observed concentration of drug in plasma.

    Day 20: -0.5, 0 (pre-dose), 0.25, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 8, 10, 12, 16, 24, 48, 72, and 96 hours post-dose

  • Multiple-Dose PK Parameter: Ctau of Cilofexor

    Ctau is defined as the observed drug concentration at the end of the dosing interval.

    Day 20: -0.5, 0 (pre-dose), 0.25, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 8, 10, 12, 16, 24, 48, 72, and 96 hours post-dose

  • Percentage of Participants With at Least One Adverse Event (AE)

    An AE is any untoward medical occurrence in a clinical study participant administered a medicinal product, which does not necessarily have a causal relationship with the treatment. An AE can therefore be any unfavorable and/or unintended sign, symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product.

    First dose date up to last dose date (Maximum: 20 days) plus 30 days

  • Percentage of Participants With Clinically Significant 12-Lead Electrocardiogram (ECG) Abnormalities

    Investigator determined the ECG findings were clinically significant.

    First dose date up to last dose date (Maximum: 20 days) plus 30 days

  • Percentage of Participants With Clinical Laboratory Abnormalities

    Treatment-emergent laboratory (Hematology, Chemistry, and Urinalysis) abnormalities were defined as values that increase at least one toxicity grade from baseline. Laboratory Abnormalities are graded by the investigator as Grade 1, 2, 3, or 4 according to the modified Gilead Sciences, Inc (GSI) Grading Scale. The most severe graded abnormality from all tests was counted for each participant. Data is only reported for those Grades reported in 1 or more participants.

    First dose date up to last dose date (Maximum: 20 days) plus 30 days
