Study summary

This study was a randomized strategy trial conducted among women who received highly active antiretroviral therapy (HAART) during pregnancy for purposes of prevention of mother-to-child transmission (PMTCT) of HIV but did not otherwise meet criteria to initiate HAART for their own health. The study was designed to determine whether continuation of HAART after delivery or other pregnancy outcome reduced morbidity and mortality compared to discontinuation and re-initiation of HAART when protocol specified criteria were met.

Read the detailed description

This randomized strategy trial addressed therapeutic questions for women from regions where antepartum HAART for PMTCT (for all CD4+ cell counts) and postpartum formula feeding is standard of care, and who also had both a pre-HAART CD4+ cell count >400 cells/mm\^3 and a screening (on-HAART) CD4+ cell count > 400 cells/mm\^3. For these women, the objectives related to the relative efficacy and safety of continuing HAART (when it is no longer used for PMTCT) versus discontinuing HAART.

Potential participants were identified/recruited and consented during pregnancy or after delivery or other pregnancy outcome. Study-specific screening was initiated in the third trimester or after pregnancy outcome. Women who were screened for the study were counseled to continue their HAART until they were randomized.

Randomization would occur within 0-42 days after pregnancy outcome. Women who did not carry their pregnancy to the third trimester but otherwise meet study eligibility criteria could be enrolled.

Participants were randomized to one of the two study arms:

Arm A: Continuation of HAART Arm B: Discontinuation of HAART and resume HAART when protocol-specified criteria were met

Participants were to be followed until 84 weeks after the last participant was randomized.

Key evaluations were conducted at Screening, Entry, post entry visits were scheduled to take place 4 weeks after entry, 12 weeks after entry, and every 12 weeks thereafter. Key evaluations included physical examinations, clinical assessments, and blood collection.

On 7 July 2015, the study sites received formal communications regarding the results of the Strategic Timing of Antiretroviral Treatment (START) study and associated changes were implemented to the 1077HS study in response to these results. All sites were instructed that all women in the 1077HS study were to be informed of the START study results and that antiretroviral therapy (ART) was recommended for all women based on the START study results.

Terms in these criteria, in plain language(11)

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.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

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.

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.

CD4 count

The number of CD4 cells, a type of white blood cell, in a given amount of blood. It is used to follow how well the immune system is doing in HIV.

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.

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).

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.

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.

Creatinine clearance (CrCl)

How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

Interventions

  • DrugHighly active antiretroviral therapy (HAART)

    A combination of three or more HIV medications belonging to two or more drug classes. The preferred study-supplied HAART regimen was lopinavir/ritonavir (LPV/RTV) plus fixed dose combination tenofovir/emtricitabine (TDF/FTC). Additional ARVs provided for use in this study included fixed dose combination lamivudine/zidovudine (3TC/ZDV), lamivudine (3TC), zidovudine (ZDV), tenofovir (TDF), fixed dose combination tenofovir/emtricitabine/rilpivirine (TDF/FTC/RPV), didanosine (ddI), atazanavir (ATV), raltegravir (RAL), and ritonavir (RTV). While LPV/RTV plus TDF/FTC was the preferred study-supplied regimen, the study clinicians in conjunction with participants would determine the optimal drug combination for each participant.

At time of confirmation of VF. HIV-1 RNA testing to identify VF was done at week 4, 12, 24, and every 12 weeks thereafter until study end at an average of 125 weeks. If HIV-1 RNA was above 1000 copies/ml, confirmatory testing was done within 4 weeks.

SecondaryQuality of Life (QoL) - Health Rating Score

QoL - health rating score was evaluated by a self reported questionnaire. Health rating score of 0 was indicative of death or worst possible health and a score of 100 was being in perfect or best possible health and the mean of score is calculated. Higher scores indicate better Quality of Life (QoL). The range is 0-100 units on a scale

SecondaryChanges in Plasma Concentrations of Inflammatory and Thrombogenic Markers

This outcome was intended as an exploratory analyses and was not included in the primary analyses conditional on primary results and funding. This outcome required additional funding for laboratory testing which was not available and so this outcome is not reported.

Time frame:
Measured at baseline, after 4 and 12 weeks, and then every 6 months until study termination. All participants were followed until July 7, 2015 (an average of 125 weeks of follow-up).

No measurements were reported for this outcome.

SecondaryCost Effectiveness and Feasibility of Treatment Models

This outcome was intended as an exploratory analyses and was not included in the primary analyses. Given the results of the primary analyses and changes in WHO guidelines to recommend lifelong antiretroviral therapy, the protocol team decided that this outcome was no longer scientifically important. No resources and funding was allocated by NIH.

Time frame:
Measured at baseline, after 4 - 12 and 24 weeks, and then every 6 months until study termination. All participants were followed until July 7, 2015 (an average of 125 weeks of follow-up).

No measurements were reported for this outcome.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Jan 2010 to primary completion in Aug 2016, 79 months.

Results were first posted in Feb 2018, 1 year 5 months after primary completion.

Of 78 non-industry phase 4 interventional studies under HIV Infections, half reached primary completion within 36 months of starting (the median), counting those still running; a quarter within 25 and three quarters within 45. This study's 79 months is above that.

Counting every sponsor, half of 90 studies reached it within 35 months; a quarter within 23 and three quarters within 44.

How these figures are worked out, and which studies are left out of them.

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 Aug 14, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
