Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

For Control Group 1 (Normal Renal Function):

  • Medical history and physical examination without any ongoing clinically relevant findings as judged by the Investigator
  • No clinically relevant findings (only minor deviations) in biochemistry, hematology, coagulation, and urinalysis examinations for the age of the participant, as judged by the Investigator; absolute lymphocyte count and absolute neutrophil count must be within normal limits

For Group 2 (Impaired Renal Function):

  • Medical history and physical examination without any ongoing clinically relevant findings except for the underlying disease leading to renal impairment and consequence diseases thereof
  • Chronic kidney disease
  • For participants under medication, stable medication for at least 1 month
  • Other protocol defined inclusion criteria could apply

Exclusion Criteria:

  • History or presence of respiratory, gastrointestinal (including bariatric or other gastric surgeries, or other conditions that may affect drug absorption), hepatic (including hepatorenal syndrome), hematological, lymphatic, cardiovascular (such as ventricular dysfunction and congestive heart failure, cardiac arrythmia), psychiatric, neurological, genitourinary, immunological, dermatological, connective tissue diseases, or disorders that may affect the safety of the participant.
  • History of drug hypersensitivity, ascertained or presumptive allergy/hypersensitivity to the active drug substance and/or formulation ingredients; history of serious allergic reactions leading to hospitalization or any other hypersensitivity reaction in general, which may affect the safety of the participant and/or outcome of the study per the Investigator's discretion
  • History or presence of epilepsy, neurological disorders with seizure propensity or undiagnosed loss of consciousness, severe head trauma within 6 months or severe depression within 12 months prior to Screening), or neuropsychiatric conditions
  • History of serotonin syndrome
  • Prior history of cholecystectomy or splenectomy, and any clinically relevant surgery within 6 months prior to Screening, which might interfere with the objectives of the study or the study procedures
  • Other protocol defined exclusion criteria could 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
Time Frame
Pharmacokinetic (PK) Plasma Concentrations of Enpatoran
Time Frame: Predose, 0.5, 1, 1.5, 2, 4, 8, 12, 24, 36, and 48 hours postdose
Predose, 0.5, 1, 1.5, 2, 4, 8, 12, 24, 36, and 48 hours postdose

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
Time Frame
Number of Participants with Treatment-Emergent Adverse Events (TEAEs)
Time Frame: Up to Day 35
Up to Day 35
Number of Participants with Abnormal Vital Signs, Laboratory Variables and 12-Lead Electrocardiogram (ECG)
Time Frame: Baseline and up to Day 35
Baseline and up to Day 35

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
