Pharmacokinetics of Entospletinib in Adults With Normal and Impaired Liver Function

May 24, 2019 updated by: Gilead Sciences

A Phase 1, Open-Label, Multiple Dose Study to Evaluate the Pharmacokinetics of Entospletinib in Subjects With Normal and Impaired Hepatic Function

The primary objective of this study is to evaluate the pharmacokinetics of entospletinib (ENTO) and/or its metabolites (if applicable) in participants with impaired hepatic function (stratified by smoking status, as appropriate) relative to matched, healthy controls.

Intervention / Treatment

Intervention / Treatment

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Key Inclusion Criteria:

  • Calculated body mass index from 18 to 40 kg/m^2
  • Not pregnant
  • Normal electrocardiogram
  • Participants with impaired liver function must be sufficiently healthy based upon medical history and physical examination, vital signs, and screening laboratory evaluations.

Key Exclusion Criteria:

  • Participation in another clinical study (current or within last 30 days)
  • HIV, hepatitis B virus, or active hepatitis C virus infection

Note: Other protocol defined Inclusion/Exclusion criteria may apply.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Pharmacokinetic (PK) Parameter: AUCtau of ENTO
Time Frame: 0 (predose), 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, 18, 24, 36, 48, 60, 72, 84, and 96 hours postdose on Day 5
AUCtau is defined as concentration of drug over time (the area under the concentration verses time curve over the dosing interval).
0 (predose), 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, 18, 24, 36, 48, 60, 72, 84, and 96 hours postdose on Day 5
Pharmacokinetic (PK) Parameter: Cmax of ENTO
Time Frame: 0 (predose), 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, 18, 24, 36, 48, 60, 72, 84, and 96 hours postdose on Day 5
Cmax is defined as the maximum concentration of drug.
0 (predose), 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, 18, 24, 36, 48, 60, 72, 84, and 96 hours postdose on Day 5

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants Experiencing Treatment-Emergent Adverse Events (TEAEs)
Time Frame: Baseline up to Day 9 plus 30 days

TEAEs are defined as events that meet one of the following criteria:

  • Any adverse events (AEs) with onset date of on or after the study drug start date and no later than 30 days after permanent discontinuation of study drug or
  • Any AEs leading to premature discontinuation of study drug.
Baseline up to Day 9 plus 30 days
Percentage of Participants Experiencing Treatment-Emergent Laboratory Abnormalities
Time Frame: Baseline up to Day 9 plus 30 days
Treatment-emergent laboratory abnormalities were defined as values that increase at least one toxicity grade from baseline. The most severe graded abnormality from all tests was counted for each subject.
Baseline up to Day 9 plus 30 days
