Dose Escalation Study of Pharmacokinetics, Safety and Tolerability After Single Dose Administration of BILR 355 (SDS) Plus Low-dose Ritonavir in Healthy Volunteers

September 30, 2014 updated by: Boehringer Ingelheim

Phase I Sequential Dose Escalation Study of Pharmacokinetics, Safety and Tolerability After Single Dose (225 Mg-450 mg) Oral Administration of BILR 355 (SDS) Plus Low-dose Ritonavir in Healthy Volunteers

The primary objective was to explore the relative bioavailability of increasing doses of BILR 355 BS, as a sodium dodecyl sulfate-containing solid formulation (SDS), in combination with ritonavir 100 mg and to explore the dose-concentration proportionality of increasing doses.

A secondary objective was to explore the effect of food on the pharmacokinetics of BILR 355 (SDS)

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

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
AUC0-inf (Area under the concentration-time curve of the analyte in plasma over the time interval from 0 extrapolated to infinity)
Time Frame: up to 120 hours after drug administration
up to 120 hours after drug administration
Cmax (Maximum measured concentration of the analyte in plasma)
Time Frame: up to 120 hours after drug administration
up to 120 hours after drug administration
AUC0-tz (Area under the concentration-time curve of the analyte in plasma over the time interval from 0 to the last quantifiable data point)
Time Frame: up to 120 hours after drug administration
up to 120 hours after drug administration
CL/F (Apparent clearance of the analyte in plasma following extravascular administration)
Time Frame: up to 120 hours after drug administration
up to 120 hours after drug administration
Tmax (Time from dosing to the maximum concentration of the analyte in plasma)
Time Frame: up to 120 hours after drug administration
up to 120 hours after drug administration
t½ (Terminal half-life of the analyte in plasma)
Time Frame: up to 120 hours after drug administration
up to 120 hours after drug administration

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 patients with adverse events
Time Frame: up to 10 days after last dose administration
up to 10 days after last dose administration

Primary Completion (Actual)

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.
