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).

Primary | 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 | |
