About this study

Official title: A Randomized, Open-label Trial to Compare the Efficacy, Safety and Tolerability of DRV/Rtv (800mg/100mg) q.d Versus DRV/Rtv (600mg/100mg) b.i.d in Early Treatment-experienced HIV-1 Infected Subjects

The purpose of this study is to test if being treated with darunavir/ritonavir (DRV/rtv) 800/100 mg daily is as effective as being treated with DRV/rtv 600/100 mg twice daily, in early antiretroviral (ARV)-experienced patients when given along with selected optimized background regimen (OBR).

Read the detailed description

This is a randomized (the study medication is assigned by chance), open-label (all people know the identity of the intervention) study in which 590 patients will be randomly assigned to receive either DRV/rtv 800/100 mg daily or DRV/rtv 600/100 mg twice daily along with the selected OBR. An OBR will consist of at least 2 nucleoside reverse transcriptase inhibitors (NRTIs) selected by the investigator. The study will include a 4 week screening period, 48-weeks of treatment period and 4-weeks of follow-up. The study will also consists of extension phase after Week 48: in regions where DRV is not yet commercially available or reimbursed by the health care system, patients who complete the 48 weeks of treatment with DRV/rtv and who continue to benefit from this treatment, will have the opportunity to continue DRV treatment as a 600 mg twice daily dosage until DRV is reimbursed and available via the public and/or private health care system or until its development is discontinued. Safety evaluation will consists of adverse events (including specific toxicities), clinical laboratory tests, vital signs, electrocardiogram, physical and skin examination.

What is being measured

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

  1. Virological Response at Week 48 (Number of Participants With Plasma Viral Load Less Than 50 Copies/mL) - as Defined by the Time to Loss of Virologic Response (TLOVR) Algorithm

    The TLOVR algorithm was used to derive response, ie, response and loss of response needed to be confirmed at 2 consecutive visits and participants who permanently discontinued were considered nonresponders after discontinuation. Participants with intermittent missing viral load values were considered responders if the preceeding and succeeding visits indicated response. In all other cases, intermittent values were imputed with nonresponse. Resuppression after confirmed virologic failure was considered as failure in this algorithm.

    Measured: 48 Weeks

Secondary outcomes (11)
  1. Virologic Response at Week 48 (Viral Load Less Than 400 Copies/mL)

    Number of participants with confirmed plasma viral load less than 400 copies/mL at Week 48.

    Measured: 48 weeks

  2. Change in log10 Viral Load From Baseline at Week 48

    Measured: 48 weeks

  3. Time to Reach First Virologic Response

    Time (in weeks) to achieve viral load less than 50 copies/mL by the participants.

    Measured: 48 weeks

  4. Time to Loss of Virologic Response

    Time taken to lose the virologic response ie, plasma viral load less than 50 copies/mL by participants.

    Measured: 48 weeks

  5. Time-averaged Difference (DAVG) of log10 Plasma Viral Load Over 48 Weeks

    Measured: 48 weeks

  6. Change in CD4+ Cell Count From Baseline

    CD4+ cell count was calculated using the Last Observation Carried Forward (LOCF) algorithm.

    Measured: 48 Weeks

  7. Change From Baseline in Total Functional Assessment of HIV Infection (FAHI) Score

    The FAHI is a 44-item questionnaire and incorporates 5 functional scales (physical well-being, emotional well-being/living with HIV, functional and global well-being, social well-being, and cognitive functioning). Each scale included several questions (all 5 scales include total 44 questions). For each question, participants gave a score of either 0 (not at all), 1 (a little bit), 2 (somewhat), 3 (quite a bit) and 4 (very much). Total FAHI imputed score is calculated by adding scores for each question. The range of total FAHI score is 0 to 176. Higher scores indicate worsening.

    Measured: 48 weeks

  8. Percentage of Participants Adherent/Non-adherent to ARV as Determined by Modified Medication Adherence Self Report Inventory (M-MASRI) Questionnaire at Week 48

    Self-reported adherence to the ARV medications was measured. The M-MASRI asks participants to report the number of doses taken, as well as the number of doses taken during the last 30 days prior to the study visit by means of a horizontal visual analogue scale (VAS) that generates a self-rated percentage of doses of all the ARV medications taken during the past 30 days.

    Measured: 48 weeks

  9. Area Under the Curve From the Time of Study Medication Administration Upto 24 Hour Postdose (AUC24h) of DRV and Rtv

    Pharmacokinetic parameter AUC24h was assessed from the time of study medication administration upto 24 hour postdose. Population Pharmacokinetic Estimates of DRV and rtv were evaluated.

    Measured: 0 hour predose and 1 hour post dose measured at Weeks 4 and 24. Any time point measured at Weeks 8 and 48.

  10. Predose Plasma Concentration (C0h) of DRV and Rtv.

    Pharmacokinetic parameter C0h was assessed. Population Pharmacokinetic Estimates of DRV and rtv were evaluated.

    Measured: 0 hour predose and 1 hour post dose measured at Weeks 4 and 24. Any time point measured at Weeks 8 and 48

  11. Number of Participants Developing Mutations at Endpoint

    Development of Mutations in Virologic Failures (Plasma Viral Load less than 50 Copies/mL) at endpoint.

    Measured: 48 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Darunavir (DRV) and Ritonavir (rtv) in people with Human Immunodeficiency Virus - Type 1, run by Tibotec Pharmaceuticals, Ireland at 85 sites in 19 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 5 inclusion and 6 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 15 Feb 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 85 sites in United States, South Africa, Brazil, Argentina, France and 14 more countries. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 22 Sep 2010). 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?

Virological Response at Week 48 (Number of Participants With Plasma Viral Load Less Than 50 Copies/mL) - as Defined by the Time to Loss of Virologic Response (TLOVR) Algorithm (time frame: 48 Weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00524368, which also lists 1 linked publication.

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 15 Feb 2013.
