About this study

Official title: An Open-label, Multiple Dose, Cross-over Study to Evaluate the Steady-state Pharmacokinetic Parameters of Nevirapine Extended Release Tablets in HIV-1 Infected Children, With an Optional Extension Phase

The primary objective is to establish the pharmacokinetic (PK) profile at steady state of nevirapine XR in HIV infected children from >=3 to <18 years of age. This phase I trial is an open-label, multiple dose, non-randomized and cross-over study. Patients who have completed the last visit of the PK trial (visit 7) can enter into an Optional Extension Phase (OEP) until the Investigational New Drug (IND) is withdrawn; until nevirapine XR becomes approved and is available by prescription in a given country; or, the patient enrolls in a compassionate use program. During this OEP, nevirapine XR safety and efficacy information will be collected.

Study groupRoleWhat they receive
Nevirapine IR / Nevirapine XRExperimentalIn this pharmaco-kinetic (PK) cross-over design trial, all patients initially receive nevirapine immediate release and then all patients are switched to nevirapine extended release 200 mg, 300 mg or 400 mg QD. After completing the PK phase patients had the option of continuing treatment with nevirapine XR in the Optional Extension Phase (OEP).
Receives: Drug: Nevirapine Immediate Release (IR); Drug: Nevirapine Extended Release (XR)

What is being measured

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

  1. Trough Cpre,N.

    Trough Nevirapine concentration immediately prior to the next scheduled dose. Patients took Nevirapine (NVP) Immediate Release (IR) up to day 10 and had PK measurements taken on Day 11. This was followed by 9 days (from day 12 to day 20) taking NVP Extended Release (XR) with PK measurements taken on Day 22.

    The measure of dispersion presented is the coefficient of variation (%) rather than the geometric coefficient of variation.

    Measured: Day 11 prior to the next scheduled dose of Nevirapine IR and day 22 prior to the next scheduled dose of Nevirapine XR

Secondary outcomes (14)
  1. AUCt,ss

    Area under the concentration-time curve of the Nevirapine (NVP) in plasma at steady state over the time dosing interval τ.

    All patients received nevirapine IR for 10 days prior to collection of 12-hour Area Under the Curve (AUC) data. Then, all patients were switched to nevirapine XR for 9 days prior to collection of 24-hour AUC data. The treatments of IR and XR are summarized separately using geometric means and geometric coefficients of variation.

    For NVP IR AUC measured over hours: 0,1,2,3,4,8 and 12, For NVP XR AUC measured over hours: 0,1,2,3,4,8,10,12 and 24.

    Measured: Day 11 prior to the next scheduled dose of Nevirapine IR and day 22 prior to the next scheduled dose of Nevirapine XR

    Minimum measured concentration of the Nevirapine in plasma at steady state over the time dosing interval τ by nevirapine XR dose group Patients took Nevirapine (NVP) Immediate Release (IR) up to day 10 and had PK measurements taken on Day 11. This was followed by 9 days (from day 12 to day 20) taking NVP Extended Release (XR) with PK measurements taken on Day 21.

    Measured: Day 11 prior to the next scheduled dose of Nevirapine IR and day 22 prior to the next scheduled dose of Nevirapine XR

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Nevirapine Immediate Release (IR) and Nevirapine Extended Release (XR) in people with HIV Infections, run by Boehringer Ingelheim at 10 sites in 4 countries.

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 11 inclusion and 12 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 7 Jan 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 10 sites in Botswana, Germany, United States, South Africa. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

Yes. Results are posted in the registry (first posted 7 May 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Trough Cpre,N. (time frame: Day 11 prior to the next scheduled dose of Nevirapine IR and day 22 prior to the next scheduled dose of Nevirapine XR). 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 7 Jan 2016.
