PK and PD Study of IDN-6556 in Subjects With Severe Renal Impairment and Matched Healthy Volunteers

December 18, 2015 updated by: Conatus Pharmaceuticals Inc.

An Open-Label Pharmacokinetic and Pharmacodynamic Study of a Single Dose of IDN-6556 in Subjects With Severe Renal Impairment and in Matched Healthy Volunteers

This is an open-label, parallel-group study to compare the pharmacokinetics and pharmacodynamics of IDN-6556 following a single 50 mg oral dose of IDN-6556 in subjects with severe renal impairment and matched healthy volunteers with normal renal function.

Study Overview

Status

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

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Actual)

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 to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

All Subjects:

  • Male or female subjects 18 - 75 years of age, able to provide written informed consent, understand and comply with all scheduled visits, and other requirements of the study
  • Body mass index (BMI) 18.0 - 40.0 kg/m2 and body weight >50 kg
  • Willingness to utilize two reliable forms of contraception (for both males and females of childbearing potential) from screening to one month after the last dose of study drug

Matched Healthy Volunteers:

  • Medically healthy as determined by the Investigator
  • Screening creatinine clearance ≥90 mL/min using the Cockcroft-Gault equation
  • Supine blood pressure ≤145/90 mmHg
  • No significant uncontrolled systemic or major illness that, in the opinion of the Investigator, would preclude the subject from participating in and completing the study

  • Demographically comparable to subjects with severe renal impairment as follows:

    1. Mean body weight within ±10 kg
    2. Mean age within ±5 years
    3. Similar gender ratio

Severe Renal Impaired Subjects:

  • Screening creatinine clearance (CLCR) <30 mL/min using the Cockcroft-Gault equation
  • Supine blood pressure ≤170/110 mmHg
  • Documented renal impairment indicated by reduced creatinine clearance within 12 months of screening or longer
  • Stable renal function as evidenced by ≤30% difference in two measurements of creatinine clearance on two separate occasions separated by at least 28 days with one measurement being the value at screening.

Exclusion Criteria:

  • History of renal trasplant
  • Acute renal failure
  • Subjects undergoing any method of dialysis or hemofiltration
  • Evidence or history of clinically significant uncontrolled hematological, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurologic, or allergic disease (including drug allergies, but excluding untreated, asymptomatic, seasonal allergies at time of dosing)
  • Disorders or surgery of the gastrointestinal tract which may interfere with drug absorption or may otherwise influence the pharmacokinetics of the investigational medicinal product (e.g., inflammatory bowel disease, resections of the small or large intestine, etc.)
  • History of febrile illness within 5 days prior to dosing
  • Evidence of clinically significant liver disease or liver damage (e.g., hepatitis B or C, autoimmune hepatitis, primary biliary cirrhosis, non-alcoholic fatty liver disease, elevated aspartate aminotransferase (AST) or alanine aminotransferase (ALT) that is considered clinically significant by the Investigator, etc.)
  • Known infection with human immunodeficiency virus (HIV) upon serological testing
  • History or presence of clinically concerning cardiac arrhythmias, or prolongation of Screening (pre-treatment) QT or QTc interval of >480 milliseconds (msec) for subjects with severe renal impairment or >450 msec for matched healthy volunteers
  • Subjects with active or history of malignancies other than curatively treated skin cancer (basal cell or squamous cell carcinomas)

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
AUC
Time Frame: 48 hours
Area under the plasma concentration curve (AUC) parameters include AUC0-12, AUCinf, AUClast
48 hours
Cmax
Time Frame: 48 hours
Maximum concentration (Cmax)
48 hours

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.
