Study summary

The study was done to:

  • Start antiretroviral therapy (ART) early in those recently or acutely infected with HIV-1
  • See how starting ART as soon as the infection is found affects the amount of HIV-1 in blood and how well the body fights the HIV-1 infection
  • Look at the amount of HIV-1 DNA (genetic material for HIV-1) seen in CD4+ T-cells (infection-fighting cells in blood) after 48 weeks of ART
  • See how early treatment for HIV affects the numbers of HIV-1 infection fighting cells (CD4+ and CD8+ T-cells) in blood
Read the detailed description

This was a Phase II, prospective, open-label two-step study to measure the effects of early ART on the establishment of HIV-1 reservoir and HIV-1-specific immunity. Participants were enrolled if they fulfilled the inclusion criteria for acute HIV-1 infection (AHI) diagnosis within 7 days prior to entry and had an enrollment visit with the immediate initiation of ART. Plasma and serum samples for Fiebig staging were collected at the time of ART initiation.

Participants were followed for up to 216 weeks (72 weeks on Step 1 and 144 weeks on Step 2). Evaluations at weeks 2 and 8 on Step 1 were performed via telephone.

The Fiebig stage-classification system was used to characterize the progression from HIV-1 exposure to HIV-1 seroconversion at the time of ART initiation. In this study, the five Fiebig stages of interest were simplified into three study groups as described below (based on HIV-1 antibody diagnostic profile at time of ART initiation).

The primary analysis was based on Step 1. Step 2 was added to the study for long term follow-up. The rationale for the extended follow-up period was to expand the number of available participants for future therapeutic and cure studies without the burden of frequent visits and the cost of study-provided laboratory testing.

Group 1: Fiebig I/II (non-reactive HIV-1 antibody)

Group 2: Fiebig III/IV (reactive HIV-1 antibody and negative or indeterminate results on the Western Blot (WB) or Geenius HIV-1/HIV-2)

Group 3: Fiebig V (reactive HIV-1 antibody and positive WB or Geenius HIV-1/HIV-2 without p31 band)

Although participants in Fiebig VI (positive WB or Geenius HIV-1/HIV-2 with p31 band) were not specifically targeted for enrollment in this study, it was possible that a small number of participants would be determined to be in Fiebig VI (positive Western blot or Geenius HIV-1/HIV-2 with p31 band) based on analysis of the entry samples. Participants who were determined to be in Fiebig VI were followed on the study for no more than 24 weeks on Step 1, allowing ample time for them to pursue alternative sources for ART. Enrolled participants without HIV or in Fiebig VI were replaced.

The study-provided regimen was single tablet regimen elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (EVG/COBI/FTC/TAF) or bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF). Other non-study-provided antiretroviral (ARV) regimens were also allowed for participants who were pregnant, breastfeeding, or unable/unwilling to take EVG/COBI/FTC/TAF or BIC/FTC/TAF, or for participants whose local health care/primary care provider preferred starting a different initial ARV regimen.

Inclusion criteria

Appropriate documentation from medical records of diagnosis of acute -1 infection (AHI) within 7 days prior to enrollment, that includes one of the following:

  1. A detectable HIV-1 RNA within 28 days prior to study entry AND a non-reactive HIV-1 antibody within 7 days prior to entry OR
  2. A detectable HIV-1 RNA or a reactive HIV-1 antibody within 28 days prior to study entry AND a negative/indeterminate WB or negative/indeterminate Geenius HIV-1/HIV-2 Supplemental Assay within 7 days prior to entry OR
  3. A documented non-reactive HIV-1 antibody or negative HIV-1 RNA within 90 days prior to study entry AND a documented reactive HIV-1 antibody or positive WB that is negative for p31 band or a positive Geenius HIV-1/HIV-2 Supplemental Assay that is negative for p31 band within 7 days prior to entry OR
  4. ARCHITECT or GSCOMBO S/CO ≥10 within 7 days prior to entry AND a non-reactive HIV-1 antibody within 7 days prior to entry OR
  5. ARCHITECT or GSCOMBO S/CO ≥1 within 7 days prior to entry AND a non-reactive HIV-1 antibody within 7 days prior to entry AND a known prior S/CO \<0.5 within 90 days prior to entry OR
  6. ARCHITECT or GSCOMBO S/CO >0.5 but \<10 within 7 days prior to entry AND a non-reactive HIV-1 antibody within 7 days prior to entry AND detectable HIV-1 RNA within 7 days prior to entry

Note A: HIV-1 RNA result must be reported from an FDA-approved or CE-marked assay.

Note B: Since characterization of Fiebig stage using samples at the time of ART initiation was performed with results known within 12 weeks based on standardized, centralized testing, an estimated Fiebig group at enrollment based on inclusion criteria as shown in the table above will provide additional real-time monitoring for accruals into each study group.

  • Ability and willingness of candidate to provide written .
  • Ability and willingness to initiate ART at enrollment.
  • Ability and willingness to participate in scheduled study visits for up to 72 weeks.
  • Female candidates of who are not pregnant at the time of enrollment and who will receive the study-provided EVG/COBI/FTC/TAF and must agree not to participate in the conception process (ie, active attempt to become pregnant, in vitro fertilization), and if participating in sexual activity that could lead to pregnancy, the female candidate must agree to use at least one reliable form of while receiving study-provided treatment.

Female candidates are considered to be of reproductive potential if any of the following conditions apply:

  • Candidate has experienced menarche.
  • Candidate has not undergone bilateral tubal ligation, bilateral oophorectomy, or hysterectomy.
  • Candidate has not experienced menopause, defined as lack of menstruation within the preceding 12 months.

Acceptable contraceptive methods include:

  • Condoms (male or female) with or without a spermicidal agent
  • Diaphragm or cervical cap with spermicide
  • Intrauterine device
  • Hormonal contraceptive

Female candidates who are not of reproductive potential or whose male partner(s) has documented azoospermia are not required to use contraceptives. Any statement of self-reported sterility or that of her partner must be entered in the source documents.

NOTE: Acceptable documentation of lack of reproductive potential is oral or written documentation from the individual.

Female candidates who are prescribed a non-study-provided ARV regimen should discuss the safety of that regimen during conception and pregnancy with the prescribing physician. Such individuals should follow medical guidance regarding any potential need for contraception while using the non-study-provided ARV regimen.

Note: Pregnant and breastfeeding women may enroll in the study provided that they meet the eligibility requirements and have access to non-study-provided ARV regimens.

Exclusion criteria

Exclusion Criteria:

  • Positive -1 antibody test ≥90 days prior to study entry.
  • Active drug or alcohol use or dependence that, in the opinion of the site investigator, would interfere with adherence to study requirements.
  • Any acute, chronic, or recent and medical condition that, in the opinion of the site investigator, would interfere with adherence to study requirements or jeopardize the safety or rights of the participant.
  • Receipt of an study agent within 28 days prior to enrollment
  • Chronic or recurrent use of medications that modify host immune response, eg, oral or parenteral , cancer chemotherapy.
  • AHI diagnosis within 60 days after receiving any investigational ARV or HIV-1 vaccine or immune prophylaxis for HIV-1 infection.
  • Use of ARVs for pre- or post-exposure prophylaxis within 60 days prior to the diagnosis of AHI.
Terms in these criteria, in plain language(7)

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.

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.

Reproductive potential

Able to have children. For women this usually means from the first period until menopause, unless permanently unable to through surgery; for men, unless permanently sterile. Read who the line is about — participants, women, men, or their partners.

Criteria about it usually ask for contraception during the study and for a time after it.

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.

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.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

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 29, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
