Study summary

The goal of the CHAPAS-5 clinical trial is to find out how well different HIV treatments work in children and young people (from 4 weeks up to under 15 years old) living with HIV, including those starting treatment for the first time and those whose current treatment is not working well.

The study aims to learn whether newer or different combinations of medicines can better control the virus, be safer, and be easier to take.

The main questions it aims to answer are:

  • Can these treatments help children stay alive and keep their HIV virus at very low levels (viral load below 400) after 48 weeks?
  • Which treatment options are most effective, safest, and easiest for children and their carers to use?

Researchers will compare different treatment groups to see if some medicines work better than others. Participants will be given one of several HIV treatment combinations (all already used in care), and these will be compared to see if they lead to:

  • Better control of HIV
  • Fewer side effects
  • Improved quality of life

Participants will:

  • Be randomly assigned (like flipping a coin by computer) to one suitable HIV treatment
  • Take their HIV medication every day as prescribed
  • Attend clinic visits over about 1-2 years

At these visits, they will:

  • Have blood tests to check HIV levels and general health
  • Have health check-ups (e.g. weight, symptoms, side effects)
  • Answer simple questionnaires about:

    • How easy the treatment is to take
    • Mood, sleep, and wellbeing
    • Quality of life
  • Receive support to help them take their medication regularly

Some participants may also take part in optional extra studies (for example, to understand how the drugs work in the body).

Overall, this study aims to identify the best HIV treatments for children and young people, so future care can be more effective, safer, and easier to follow.

Read the detailed description

CHAPAS-5 is a study organised by an international group of researchers from the United Kingdom, Uganda, Mozambique, Zimbabwe, Italy and the Netherlands.

Background HIV is a virus that attacks the cells that help the body fight infection. This means that a person living with HIV may be more likely to become ill as they are not able to fight off other infections and cope with other illnesses. HIV is usually treated by taking three or four different medicines. Some of these medicines can be combined into one tablet. Depending on the medicines used, tablets may need to be taken either once or twice every day. The medicine is called antiretroviral therapy (ART).

The goal of HIV treatment is to make sure the HIV virus in the blood remains very low; this is called virological suppression. If this goal is achieved and sustained life-long, then people with HIV infection can live a healthy life, with a normal life expectancy. Adults living with HIV have many treatment options. This means that they can change treatments more easily if they get side-effects or if a treatment stops working.

Children and adolescents living with HIV have fewer available treatments than adults and only limited alternatives if they develop side-effects or if their current treatment stops working. As HIV treatment needs to be life-long for a person to live a long, healthy and productive life, it is really important that better treatment options are made available to children and adolescents.

A clinical trial is a study that compares different treatments to find out which works best. Traditional trials usually compare only two treatments at a time. CHAPAS-5 uses a newer trial design that can compare several treatments at the same time in two different groups of children. It will test three treatment options for children and adolescents starting ART for the first time (ART-naïve), and four options for those already on ART whose current treatment is not working well (ART-experienced).

Which treatments are being compared?

  1. Dolutegravir/abacavir/lamivudine (DTG/ABC/3TC) - naive and experienced
  2. Dolutegravir/tenofovir alafenamide/emtricitabine (DTG/TAF/FTC) - naive and experienced
  3. Dolutegravir/lamivudine (DTG/3TC) - naive
  4. Darunavir/ritonavir (DRV/r) + tenofovir alafenamide/emtricitabine (TAF/FTC) - experienced
  5. Darunavir/ritonavir (DRV/r) + abacavir/lamivudine (ABC/3TC) - experienced

Additional treatments, such as long-acting injectables, may be added to the trial as they become available. These could remove the need for daily pills and help improve adherence.

Who can join the trial? CHAPAS-5 will enrol participants in Uganda, Zimbabwe, and Mozambique.

The study includes children and adolescents aged at least 4 weeks to less than 15 years and weighing 3 to less than 30kg who:

  • Are starting ART for the first time, or
  • Are already on DTG-based ART but their HIV is not suppressed, and
  • Have at least two treatment options in the trial that their doctor considers suitable for them.

What will be measured?

  • How well the virus is controlled using a blood test called the viral load
  • Side effects from the treatment
  • How well children are able to take their treatment as prescribed
  • How easy the treatment is to take and how well it fits into daily life
  • Mental health and quality of life
  • The costs of different treatment options and how cost-effective they are

Participants are followed for at least 48 weeks.

Novel design CHAPAS-5 uses a novel design called the Personalised Randomised Controlled Trial (PRACTical) design. This means that each participant will be randomly allocated to receive a treatment from a list which contains only the treatment options that are appropriate for them. The treatments will be ranked from best performing to worst performing based on how well they work for participants. This will researchers to identify which treatments work best for different groups of children.

Why this trial matters? CHAPAS-5 aims to identify the best treatments for children that work well and are easy to take, with fewer side effects. The trial will also evaluate point-of-care CD4 testing to speed up diagnosis and treatment for children with advanced HIV disease and assess targeted resistance testing to identify those who may need to change treatment.

Broader Implications CHAPAS-5 not only tests different treatment options but aims to speed up the testing of HIV treatments for children so that better options can become available more quickly. The trial findings will help inform national and international guidelines and country treatment policies. This could improve future HIV treatment options for children and adolescents living with HIV.

If results become available after randomisation and meet exclusion criteria, the participant must be recalled and withdrawn from the trial and the InCTU trial physician contacted to discuss clinical management.
Terms in these criteria, in plain language(8)

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.

Line of therapy

A line of therapy is one course of treatment, which may combine several drugs. First-line is the first course given; second-line follows when that stops working or is not tolerated.

“Two prior lines” means two courses that count separately under the study’s rules — not simply two drugs. Ask the study team if you are unsure how yours are counted.

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.

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

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.

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.
