About this study

Official title: Safety, Tolerability, and Adherence to a Raltegravir-based Antiretroviral Regimen for HIV Non-occupational Postexposure Prophylaxis

The use of anti-HIV drugs following a potential sexual or injecting drug use exposure to HIV in order to try and prevent an exposure from becoming an infection is common. This is called nonoccupational postexposure prophylaxis (NPEP). The likelihood of NPEP succeeding is related to intrinsic qualities of the drugs used which includes at which point in the life cycle of the HIV virus the drugs work, how strong the drugs are against HIV, and how well tolerated the drugs are i.e. what side effects they produce. Many people skip doses during their treatment or abandon their treatment because of side effects. The anti-HIV drug raltegravir works early in the life cycle of the virus i.e. before it integrates with human DNA, is potent against HIV and causes few side effects. These qualities make it an obvious choice for use as a NPEP treatment. In this study 100 HIV negative men will receive raltegravir along with another HIV drug called truvada (commonly used in NPEP) for 28 days after a possible sexual exposure to HIV. They will be monitored closely for adverse events, side effects and for their ability to take the medicine each day for the whole 28 days. The hypothesis in this study states that raltegravir use in NPEP will be safe, well tolerated and result in a high treatment completion rate.

Read the detailed description

This is a single site, 72-week, prospective, open-label, non-randomized trial. One hundred and 50 (150) eligible participants will be assigned to receive RAL 400 mg BID along with tenofovir disoproxil fumarate/emtricitabine (TVD) 1 tablet once daily (3-drug NPEP) for 28-days or TVD 1 tablet once daily (2-drug NPEP) for 28-days according to established Australian guidelines for the use of 3 or 2-drug NPEP following a potential or actual sexual exposure to HIV in men who have sex with men (MSM).1 Based on hospital NPEP data over the past 2 years, it is anticipated that 100 MSM will receive 3-drug (RAL-TVD) NPEP and 50 will receive 2-drug (TVD) NPEP. Follow-up post NPEP is for 23 weeks i.e. to week 24 post exposure.

Primary study objectives:

To describe the safety of 28 days of nonoccupational post-exposure prophylaxis(NPEP) containing raltegravir (RAL) To describe the tolerability of 28 days of NPEP containing RAL To describe on-drug adherence and regimen completion rates of 28 days of NPEP containing RAL

Secondary study objectives:

To investigate whether or not receipt of NPEP decreases, increases or has no impact on HIV risk taking behaviour To describe the effects of RAL and tenofovir disoproxil fumarate/emtricitabine (TVD) on key inflammatory biomarkers in a subset of the main study population

What is being measured

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

  1. To describe the safety of 28 days of nonoccupational post-exposure prophylaxis containing raltegravir

    Objective AE and SAE data collection/grading utilising DAIDS data collection tool. Measurement of weight and vital signs, electrolytes, urea, creatinine, eGFR, inorganic phosphate, calcium, liver function, glucose, amylase, lipase, creatine kinase, lactate, urinalysis

    Measured: 28 days on drug with 5 month follow-up

  2. To describe the tolerability of 28 days of NPEP containing raltegravir

    Subjective reporting of AEs with data collection/grading utilising DAIDS-AE

    Measured: 28 days on-drug and 5 months follow-up

  3. To describe on-drug adherence and regimen completion rates of 28 days of NPEP containing raltegravir

    Adherence measurement by self report and pill count at 3 time points during the 28-days of NPEP

    Measured: 28 days

Secondary outcomes (3)
  1. To describe the context of the risk

    Context of risk event described using directed questioning around pre determined variables

    Measured: Baseline visit day 1 of NPEP

  2. To investigate whether or not receipt of NPEP decreases, increases or has no impact on future HIV risk taking behaviour

    Baseline data collection of HIV risk behaviour in 6 months preceeding NPEP. Repeat data collection at week 12 and week 24 post NPEP risk event. Data collected utilising assisted completion of HIV related behaviour questionaire.

    Measured: Visit 2 (day 3-5 of study), visit 7 (day 82-84 of study) visit 9 (day 166-168 of study)

  3. To describe the effects of raltegravir and truvada on key inflammatory biomarkers

    Measurement of CR-P, D-Dimer, IL-6 on a subset of 50 patients receiving raltegravir/truvada NPEP and a subset of 25 patients receiving truvada alone as NPEP.

    Measured: Day 1 and day 28 of NPEP

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Raltegravir in people with HIV Prevention and HIV Infections, run by Andrew Carr at 2 sites in Australia.

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 1 inclusion and 10 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 17 Apr 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Australia. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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?

To describe the safety of 28 days of nonoccupational post-exposure prophylaxis containing raltegravir (time frame: 28 days on drug with 5 month follow-up). The study lists 3 primary outcomes in all. 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 NCT01087840, 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 17 Apr 2014.
