In the United States, most children with HIV are receiving antiretroviral therapy (ART), making treatment-experienced children the norm. Providers may consider antiretroviral (ARV) regimen changes for the following reasons:

  • Treatment simplification: Modifying ARV regimens in children who are currently receiving effective ART to simplify the
  • Treatment optimization: Increasing the treatment potency or barrier to resistance of an effective but older or potentially fragile regimen or improving the adverse-event
  • Toxicity management: Recognizing and managing ARV drug toxicity or intolerance (see Management of Medication Toxicity or Intolerance).
  • Treatment failure: Recognizing and managing treatment failure (see Recognizing and Managing Antiretroviral Treatment Failure).

Modifying Antiretroviral Regimens in Children with Sustained Virologic Suppression on Antiretroviral Therapy

Panel’s Recommendations
  • Children who have sustained virologic suppression on their current antiretroviral (ARV) regimen should be evaluated regularly for opportunities to change to a new regimen that facilitates adherence, simplifies administration, increases ARV potency or barrier to drug resistance, and decreases the risk of drug-associated toxicity (AII).
  • Before changing a patient’s ARV regimen, clinicians must carefully consider the patient’s previous regimens, past episodes of ARV therapy failure, prior drug-resistance test results, drug cost, and insurance coverage, as well as the patient’s ability to tolerate the new drug regimen (AIII). Archived drug resistance can limit the antiviral activity of a new drug regimen.
  • Children should be monitored carefully after a change in treatment. Viral load measurement is recommended 2 to 4 weeks after a change in a child’s ARV regimen (BIII).

Rating of Recommendations: A = Strong; B = Moderate; C = Optional

Rating of Evidence: I = One or more randomized trials in childrenwith clinical outcomes and/or validated endpoints;

I* = One or more randomized trials in adults with clinical outcomes and/or validated laboratory endpoints with accompanying data in childrenfrom one or more well-designed, nonrandomized trials or observational cohort studies with long-term clinical outcomes; II = One or more well-designed, nonrandomized trials or observational cohort studies in childrenwith long-term outcomes; II* = One or more well-designed, nonrandomized trials or observational studies in adults with long-term clinical outcomes with accompanying data in childrenfrom one or more similar nonrandomized trials or cohort studies with clinical outcome data; III = Expert opinion

Studies that include children or children/adolescents, but not studies limited to postpubertal adolescents

Clinicians choose initial ARV regimens for children with HIV by evaluating the pharmacokinetic, safety, and efficacy data for the drugs that are available in formulations suitable for the child’s age and weight at the start of treatment. New ARV drug options may become available as children grow and learn to swallow pills and as new drugs, drug formulations, and data become available. Even in cases wherein patients have achieved sustained virologic suppression (i.e., suppression for 6–12 months) on their current regimen, clinicians should consider switching patients to new ARV regimens to permit the use of pills instead of liquids, reduce pill burden, allow the use of once-daily medications, reduce the risk of adverse events, minimize drug interactions, and align a child’s regimen with widely used, efficacious adult regimens.1 These changes often enhance adherence and improve quality of life.2

Treatment Simplification

Many infants and children with HIV initiated treatment with twice-daily dosing (especially prior to the approval of integrase strand transfer inhibitor [INSTI] medications ), and regimens included a variety of drug formulations, depending on which formulations were available for a child’s age and weight. Clinicians should regularly review treatment options as children grow, because it may be possible to simplify dosing using coformulated drugs and/or once-daily regimens (see Table 1 below). Clinicians also should consider a child’s ART history, drug-resistance test results. Small studies have shown that children who achieve virologic suppression using twice-daily dosing for certain ARV drugs (e.g., abacavir [ABC]) maintain virologic suppression when they are switched from twice-daily dosing to once-daily dosing of the same drugs (see the Abacavir and Nevirapine sections and fixed-dose combinations [FDCs] in Appendix A, Table 1. Antiretrovirals Available in Fixed-Dose Combination Tablets and Appendix A, Table 2. Antiretroviral Fixed-Dose Combination Tablets: Minimum Body Weights and Consideration for Use in Children and Adolescents). However, these studies reported mixed results when switching the dosing for lopinavir/ritonavir (LPV/r) from twice daily to once daily. Therefore, once-daily dosing of LPV/r is not recommended.3-6

Long-acting injectable ARV medications may be considered a treatment simplification approach for some virologically suppressed adolescents. The co-packaged, two-drug injectable ARV regimen of cabotegravir and rilpivirine (CAB and RPV; Cabenuva) is approved by the U.S. Food and Drug Administration (FDA) for use in children weighing ≥35 kilograms and ≥12 years of age, with viral suppression (defined as <50 copies/mL), on a stable ARV regimen, without a history of treatment failure, and without known or suspected drug resistance to either drug. Studies in adults—such as the First Long-Acting Injectable Regimen (FLAIR) and Antiretroviral Therapy as Long-Acting Suppression (ATLAS) trials—have demonstrated non-inferiority in those receiving monthly CAB and RPV injections compared to adults who stayed on a daily three-drug oral regimen.7,8 Similarly, in the ATLAS-2M trial, injections of CAB and RPV every 2 months were found to be non-inferior to monthly injections.9 The International Maternal Pediatric Adolescent AIDS Clinical Trials (IMPAACT) Study 2017 is currently evaluating CAB and RPV in children 12 to 18 years of age. either CAB or RPV, showed acceptable pharmacokinetics, lack of new safety concerns,7,8 and high acceptability from youth and their caregivers. This ongoing study is now assessing the full two-drug injectable regimen. The Panel on Antiretroviral Therapy and Medical Management of Children Living with HIV (the Panel) notes that significant questions remain, including whether an oral lead-in is beneficial and acceptable in the adolescent population, if there are additional adverse effects specific to the pediatric population, if a two-drug nucleoside-sparing regimen for children with significant ARV treatment history10 will be effective, and what potential implementation challenges will emerge. However, given the FDA approval for those as young as 12 years of age, some providers may consider injectable CAB and RPV in adolescents who meet the approved indications and may benefit from a long-acting injectable regimen. See Cabotegravir and Rilpivirine for additional information about these drugs and the dosing and administration of CAB and RPV, and see Management of the Treatment-Experienced Patient: Optimizing Antiretroviral Therapy in the Setting of Viral Suppression in the Adult and Adolescent ARV Guidelines for practical considerations.

Treatment Optimization

The aims of treatment optimization may include improving the potency of the regimen, improving a child’s growth or other health outcomes through reduced drug side effects and/or better treated HIV, or maximizing palatability. More studies are directly evaluating treatment optimization in children, and early results support the safety and efficacy of regimen switches for those with viral suppression. Older studies have demonstrated sustained viral suppression and improved growth outcomes in young children who have demonstrated good adherence and no baseline resistance and who were switched from LPV/r-based regimens an efavirenz (EFV)-based regimen (NEVEREST 3).15-17 Replacing LPV/r with EFV may provide some benefits (e.g., once-daily dosing and a different side- effect profile), but most pediatric HIV experts would prefer replacing LPV/r with an equally potent PI (e.g., darunavir [DRV] or atazanavir [ATV]) or an INSTI (e.g., elvitegravir [EVG], raltegravir, DTG, or bictegravir [BIC]), based on studies in adults and emerging evidence of non-inferiority or superiority in children.18,19 Although not a switch trial, findings from the randomized controlled Once-daily DTG-based ART in Young People vs. Standard Therapy (ODYSSEY) study of more than 700 children aged <18 years in eight countries showed superior virologic and clinical outcomes in children randomized to optimization with DTG-based ART compared with those in the standard of care (PI- or non-nucleoside reverse transcriptase inhibitor [NNRTI]-based regimens), contributing to evidence supporting optimization with DTG- based regimens.20 Additionally, several observational studies in sub-Saharan Africa that are evaluating efforts to optimize pediatric ARV regimens have shown improved viral suppression rates in children that were switched to DTG-based regimens.22-25 Similarly, a retrospective study from six African countries reporting on 2,655 children aged 0 to ≤19 years demonstrated sustained high levels of viral suppression in children optimized from NNRTI- and PI- based regimens to DTG-based regimens.26 The INSTI-based FDC regimen BIC/emtricitabine (FTC)/ tenofovir alafenamide (TAF)27,28 EVG/cobicistat/FTC/TAF has shown efficacy in adolescents. Early results from small, randomized studies also show potential for switches to newer-generation NNRTI medications—such as rilpivirine (RPV)29 and doravirine (DOR) in children and adolescents weighing ≥35 kg who have been virologically suppressed on a stable ARV regimen.

Toxicity Management

Several studies of small cohorts of children have demonstrated sustained virologic suppression and reassuring safety outcomes when drugs that have greater long-term toxicity risks are replaced with drugs that are thought to have lower toxicity risks (e.g., replacing stavudine with tenofovir disoproxil fumarate, TAF, zidovudine, or ABC; replacing PIs with NNRTIs), including improved lipid profiles.31-35 Similarly, adolescents who were switched from EFV to RPV, a newer generation of NNRTIs, showed similar rates of viral suppression with improved metabolic profiles and cognitive outcomes.29 Additionally, studies in adults have shown improved tolerability, lipid profiles, and insulin sensitivity in patients who were switched from PIs to INSTIs,36-40 and adults who were switched from EFV to an INSTI have shown improvement in neuropsychiatric symptoms. However, the use of INSTIs, as well as TAF, has been associated with weight gain in adults and adolescents, with emerging data showing an association in children.41-45  tenofovir disoproxil fumarate (<1%).

Treatment Failure

Treatment failure is another common reason providers change ARV regimens in children with HIV. This topic is covered in Recognizing and Managing Antiretroviral Treatment Failure.

Regimens That Are Not Recommended for Use in Children

Monotherapy PI regimens (DRV/r, LPV/r, ATV/r)47,48 and monotherapy regimens of DTG49,50 have been used to simplify or reduce the toxicity of regimens in adult patients who have sustained virologic suppression, but with varying success. These strategies are still being explored, but they are not currently recommended as management strategies in children because of the lack of data.48,51-54

Potential Antiretroviral Drug Switches in Children With Virologic Suppression

Table 18 below contains examples of potential ARV drug changes in children with sustained virologic suppression on their current regimen for the purpose of treatment simplification, optimization, or reduced toxicity. When considering such a change, a clinician should first ensure that a recent viral load test indicates that the child is not experiencing virologic failure and that the child has a reliable history of good adherence (assessed by self and parental report, pharmacy refill, prior viral loads, etc.). Among treatment-naive youth in the United States aged 13 to 24 years, some evidence exists that single-tablet regimens (STRs) improve the odds of viral suppression55; emerging evidence also supports the safety, efficacy, and tolerability of STRs in younger children.56-58 Although these data have not been replicated in treatment-experienced adolescents, clinicians should consider using STRs in children and youth with sustained viral suppression because these regimens reduce pill burden and dosing frequency. Clinicians also must consider ART history, tolerability, ability to swallow tablets, and all prior drug-resistance test results to avoid choosing new ARV drugs for which archived drug resistance would reemerge and limit the activity of the regimen.59-63 The evidence that supports many of these ARV changes is indirect, that is, extrapolated from data about drug performance during initial therapy or follow-up therapy after treatment failure. When such changes are made, careful monitoring (e.g., taking a viral load measurement 2–4 weeks after making the switch to the new regimen) is important to ensure that virologic suppression is maintained.

a The possibility of planned and unplanned pregnancy should be considered when selecting an ART regimen for an adolescent. When discussing ART options with adolescents of childbearing potential and their caregivers, it is important to consider the benefits and risks of all ARV drugs and to provide the information and counseling needed to support informed decision-making; refer to the Perinatal Guidelines (see Recommendations for Use of Antiretroviral Drugs During Pregnancy, Table 7. Situation- Specific Recommendations for Use of Antiretroviral Drugs in Pregnant People and Nonpregnant People Who Are Trying to Conceive, and Appendix C: Antiretroviral Counseling Guide for Health Care Providers).

b For infants and young children who are being treated with liquid formulations of ABC, initiation with once-daily ABC is not generally recommended. In clinically stable patients with undetectable viral loads who have had stable CD4 T lymphocyte cell counts on twice-daily ABC, the dose can be changed from twice daily to once daily. ABC is not approved by the U.S. Food and Drug Administration for use in neonates and infants aged <3 months. Recent data from the IMPAACT P1106 trial and two observational cohorts provide reassuring evidence of the safety of ABC in infants aged <3 months. Based on these data, clinicians may consider the use of ABC in infants aged ≥1 month to <3 months, in consultation with a pediatric HIV specialist (see Abacavir).

c For children and adolescents weighing ≥14 kg to <35 kg, TAF can be used in combination with an INSTI or an NNRTI, but not a boosted PI. For children and adolescents weighing ≥35 kg, TAF can be used in combination with an INSTI, an NNRTI, or a boosted PI.

d RAL is recommended for twice-daily use in children. Chewable tablets can be used as dispersible tablets starting at 4 weeks of age. RAL HD once daily is only recommended for virologically suppressed children weighing ≥40 kg.
