Study summary

The purpose of this pilot study is to assess the efficacy and safety of the combination of RAL+ATV/r in comparison with TDF/FTC+ATV/r in HIV-1 infected patients presenting virologic failure and PI and TDF naïve.

Read the detailed description

Overall Study Design and Plan: Description

This is a pilot, randomized, open-label study. All the participants will be assigned to receive RAL+ATV/r or TDF/FTC+ATV/r. Patients will be evaluated at screening, randomization (day 0), and on weeks 4, 8, 12, 24, 36 and 48.

At the screening visit, subjects must be willing and able to give written (signed and dated) informed consent prior to any study specific procedures. They will receive a unique screening number and will undergo the study procedures associated with the screening visit. The investigator will evaluate whether the subject meets all eligibility criteria specified and record the details of the informed consent process and the results of this assessment in the subject's medical records. Two forms of the ICF will be signed, one for the subject and the other to file at the site.

At baseline visit, enrollment criteria will be reviewed and subjects who meet all of them will undergo study procedures. Subjects will receive instructions about study medications and dosing schedule. Subjects should start study medication within 24 hours of the baseline visit. Subjects will return to the investigator´s site for study visits and procedures. Subjects who prematurely discontinue the study must return for a discontinuation visit and undergo the study procedures identified for the discontinuation visit.

Exclusion criteria

Exclusion Criteria:

  • Patient has a current (active) diagnosis of acute hepatitis due to any cause OR chronic and/or C WITH (AST) and/or alanine aminotransferase (ALT) >2.5 x (ULN) AND/OR is likely to require hepatitis treatment in the next year.
  • Active hepatitis B infection (positive HBsAg), regardless of stage of infection.
  • Subject has a currently active AIDS defining illness (Category C conditions according to the CDC Classification System for infection 1993) in the last 30 days.

    • \<8.0 g/dL
    • \<750 cells/µL
    • count \<50,000 mm3
    • Creatinine >1.5 x ULN
  • Any condition that, in the investigators opinion, could compromise the subject's safety or adherence to the trial protocol.
  • The use of any study agent within 30 days prior to screening.
  • Use of drugs, cytokines inhibitors or other cytokines in the previous year.
  • Any other condition (including, without limitation, the use of alcohol or drugs) that in the investigator's opinion may compromise the safety of the patient or his/her adherence to the protocol.
Terms in these criteria, in plain language(10)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Postmenopausal

Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

Hemoglobin (Hb)

The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).

Absolute neutrophil count (ANC)

The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.

It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 24, 2017, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
