What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Maximum observed concentration of the analyte in the plasma (Cmax)

    Measured: up to 120 hours after start of treatment

  2. Time from dosing to the maximum concentration of the analyte in plasma (tmax)

    Measured: up to 120 hours after start of treatment

  3. Area under the concentration-time curve of the analyte in plasma at different time points (AUC)

    Measured: up to 120 hours after start of treatment

  4. Apparent terminal half-life of the analyte in plasma (t1/2)

    Measured: up to 120 hours after start of treatment

  5. Apparent clearance of the analyte in plasma after extravascular multiple dose administration (CL/F)

    Measured: up to 120 hours after start of treatment

  6. Total mean residence time of the analyte in the body (MRTtot)

    Measured: up to 120 hours after start of treatment

  7. Apparent volume of distribution of the analyte during the terminal phase λz following extravascular administration (Vz/F)

    Measured: up to 120 hours after start of treatment

  8. Renal clearance of the analyte determined over the dosing interval τ (CLR)

    Measured: up to 120 hours after start of treatment

  9. Amount of the analyte excreted into urine (Ae)

    Measured: up to 72 hours after start of treatment

Secondary outcomes (7)
  1. Number of participants with clinically relevant changes in laboratory parameters

    Measured: up to 10 days after start of treatment

  2. Number of participants with clinically relevant changes in vital signs (blood pressure, pulse-, respiratory rate, body temperature)

    Measured: up to 10 days after start of treatment

  3. Number of participants with clinically relevant changes in 12-lead ECG

    Measured: up to 10 days after start of treatment

  4. Number of participants with clinically relevant changes in faecal occult blood testing

    Measured: up to 10 days after start of treatment

  5. Number of participants with adverse events

    Measured: Up to 25 days

  6. Global tolerability assessment by investigator on a 5-point scale

    Measured: Up to 10 days after start of treatment

  7. Number of participants with clinically relevant changes in neurological assessment

    Assessment of central nervous system function including Romberg's test, heel-to-toe straight line, and finger-nose tests

    Measured: up to 10 days after start of treatment

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing BILR 355 BS, Grapefruit juice and Nelfinavir in people with Healthy, run by Boehringer Ingelheim.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 19 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 6 Oct 2014. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Maximum observed concentration of the analyte in the plasma (Cmax) (time frame: up to 120 hours after start of treatment). The study lists 9 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Oct 2014.
