About this study

Official title: To Determine the Effect of the Modified SQV/r (Saquinavir-boosted by Ritonavir) Regimen (500/100 mg for the 1st Week Followed by 1000/100 mg for the 2nd Week) on the QTc Interval, Pharmacokinetics, and Antiviral Activity in Treatment-naive HIV-1 Infected Patients

This open-label study will evaluate the safety, pharmacokinetics and antiviral activity of a modified Invirase (saquinavir)/ritonavir regimen in treatment-naïve HIV-1 infected patients. Patients will receive Invirase 500 mg plus ritonavir 100 mg twice daily orally for the first week, followed by Invirase 1000 mg plus ritonavir 100 mg twice daily orally for the second week. The study treatment will be given in combination with two Nucleoside Reverse Transcriptase Inhibitors (NRTIs), in accordance with the current clinical HIV treatment guidelines. Anticipated time on study treatment is 14 days.

Receives: Drug: Nucleoside Reverse Transcriptase Inhibitor (NRTIs); Drug: ritonavir; Drug: saquinavir [Invirase]

What is being measured

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

  1. Maximal increase in QTc interval (continuous Holter 12-lead ECG monitoring time points Days 1, 3, 4, 7, 10 and 14)

    Measured: 14 days

Secondary outcomes (5)
  1. Pharmacokinetics: Plasma concentrations

    Measured: Pre-dose and 2, 4, 6, 8 and 12 hours post-dose, Days 3, 4, 7, 10 and 14

  2. Pharmacodynamics: Change in HIV-RNA levels

    Measured: from baseline to Day 14

  3. Safety: Incidence of adverse events

    Measured: approximately 6 months

  4. Change in ECG parameters

    Measured: from baseline to Day 14

  5. Correlation between saquinavir plasma concentration and QTc interval changes

    Measured: approximately 6 months

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Nucleoside Reverse Transcriptase Inhibitor (NRTIs), ritonavir and saquinavir [Invirase] in people with HIV Infections, run by Hoffmann-La Roche at 1 site in United Kingdom.

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 6 inclusion and 13 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 2 Nov 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United Kingdom. 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?

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?

Maximal increase in QTc interval (continuous Holter 12-lead ECG monitoring time points Days 1, 3, 4, 7, 10 and 14) (time frame: 14 days). 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 2 Nov 2016.
