Management of Children Receiving Antiretroviral Therapy

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 regimen
  • Treatment optimization: Increasing the treatment potency or barrier to resistance of an effective but older or potentially fragile regimen or improving the adverse-event profile
  • 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

Clinicians choose initial ARV regimens for children with HIV by evaluating the pharmacokinetic (PK), 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 for pediatric use), 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, and offer simplified dosing using coformulated drugs and/or once-daily regimens when appropriate (see Table 18 below). Clinicians also should consider a child’s ART history, drug-resistance test results, and ability to swallow tablets. Efforts to increase the availability of coformulated complete ARV regimens have yielded several once-daily options for children that should be considered. The International Maternal Pediatric Adolescent AIDS Clinical Trials (IMPAACT) 2019 study demonstrated safety, efficacy, and appropriate dosing of a fixed-dose combination (FDC) tablet containing abacavir, dolutegravir, and lamivudine (ABC/DTG/3TC) in children aged <12 years, with use of dispersible tablets (Triumeq PD) or an immediate-release tablet (Triumeq) to be swallowed depending on the child’s weight.3 For children weighing ≥14 kg who can swallow pills, additional options include coformulated bictegravir, emtricitabine, and tenofovir alafenamide (BIC/FTC/TAF; Biktarvy) or FTC/TAF (Descovy) plus DTG, which is a two-pill, once-daily regimen. Additional coformulated options are available when children reach 25 kg to 35 kg in weight. See Table 18 below for more information on once-daily options and other coformulated complete ARV regimens. 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 suppression4; emerging evidence also supports the safety, efficacy, and tolerability of STRs in younger children.5-7 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.

If using an FDC once-daily regimen is not possible, clinicians should determine whether the child’s ARV regimen could be simplified in other ways. For example, small studies have shown that children who achieve virologic suppression using twice-daily dosing for certain ARV drugs (e.g., 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 FDCs in Appendix A, Table 1. Antiretrovirals Available in Fixed-Dose Combination Tablets or as a Co-packaged Formulation, by Drug Class 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.8-11

Long-acting injectable (LAI) 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 kg and aged ≥12 years, 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 with adults who stayed on a daily three-drug oral regimen.12,13 Similarly, in the ATLAS-2M and SOLAR trials, injections of CAB and RPV every 2 months were found to be non-inferior to monthly injections and once-daily ART, respectively.14,15 The IMPAACT 2017 study is currently evaluating CAB and RPV in children aged 12 to 18 years. At 24 weeks of follow-up, injections of CAB and RPV every 2 months maintained viral suppression, showed acceptable PK, and demonstrated an acceptable safety profile in 144 adolescents.16 Additionally, participating youth and their caregivers reported high acceptability of the treatment and a strong preference for LAI ART over daily oral ART.17 The Panel on Antiretroviral Therapy and Medical Management of Children Living with HIV (the Panel) notes that questions remain, including whether there are additional adverse effects specific to the pediatric population, whether a two-drug nucleoside-sparing regimen for children with significant ARV treatment history18 will be effective, and what potential implementation challenges will emerge. A single site in the United States has reported on three adolescents and young adults who experienced viremia while on bimonthly injections which resolved with monthly injections. Two of the individuals also experienced postinjection adverse events that self-resolved.19 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 the Cabotegravir and Rilpivirine sections 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.

Oral two-drug regimens have some data supporting efficacy in pediatric and adult populations. A two-drug FDC tablet containing DTG/RPV—a nucleoside-sparing, dual-therapy regimen that is marketed as Juluca—is approved by the FDA as a complete regimen to replace the current ARV regimen in adult patients who have been virologically suppressed (HIV RNA <50 copies/mL) on a stable ARV regimen for at least 6 months and who have no history of treatment failure. This approval was based on two Phase 3 clinical trials, SWORD-1 and SWORD-2, in which treatment-experienced adults who were virologically suppressed on three- or four-drug regimens were randomized either to switch to DTG/RPV (early-switch group) or stay on their original regimens through 48 weeks and then switch to DTG/RPV (late-switch group). Results from these trials showed similar rates of virologic suppression in both groups (non-inferiority) through 3 years of follow-up.20-22 No equivalent data exist for this drug combination in pediatric patients, although a clinical trial is underway in children aged 6 to 12 years. The Panel usually endorses the use of adult formulations in adolescents, and this product may be appropriate for certain adolescents. DTG/RPV regimens could be useful in patients in whom there is concern for toxicity from nucleoside reverse transcriptase inhibitors (NRTIs). Additionally, findings from the PENTA-17 SMILE study evaluating darunavir/ritonavir (DRV/r) combined with an INSTI, including 318 children aged 6 to 18 years in 11 countries, found that DRV/r plus an INSTI was non-inferior to the standard of care in maintaining virologic suppression at 48 weeks in participants without INSTI or protease inhibitor (PI) resistance.23 Although the Panel does not recommend this combination for initial treatment, it might be considered in situations in which simplification or avoidance of NRTIs is desired. DTG/3TC (Dovato) also has demonstrated non-inferiority to continuation of three- or four-drug regimens in treatment-experienced adults and those without a history of treatment failure in the TANGO and SALSA studies, respectively.24,25 In the ongoing DANCE study, DTG/3TC is being evaluated as an initial regimen in ART-naive adolescents aged 12 to <18 years and weighing ≥25 kg and with HIV RNA of 1,000 copies/mL to ≤500,000 copies/mL. Safety and efficacy of DTG/3TC were comparable to adults, and 22 of 32 participants achieved viral suppression at 96 weeks.26 Based on these findings, the FDA has approved DTG/3TC in adolescents aged ≥12 years and weighing ≥25 kg as an initial regimen or for those on a stable ART regimen with no history of treatment failure and no known drug resistance to the individual drugs. The Panel notes that adolescents may have difficulties adhering to therapy and recommends close monitoring with viral load testing in anyone on oral two-drug regimens. The Panel does not recommend two-drug regimens for initial ART in children (see What to Start).

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 to an efavirenz (EFV)-based regimen (NEVEREST 3).27-29 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 BIC), based on studies in adults and emerging evidence of non-inferiority or superiority in children.30,31 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 initiating DTG as first- or second-line therapy 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.32 Results from the younger ODYSSEY cohort of children weighing between 3 kg and 14 kg also showed superiority of DTG-based ART compared with other regimens, more than 70% of which were PI-based regimens.33 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.34-36 Similarly, a retrospective study from six African countries reporting on 7,898 children and adolescents aged 0 to ≤19 years demonstrated that 93% remained virologically suppressed after switching from NNRTI- and PI-based regimens to DTG-based regimens, and nearly 80% of those previously unsuppressed achieved viral suppression while on DTG.37 The INSTI-based FDC regimen BIC/FTC/TAF also has shown efficacy and high rates of long-term viral suppression in adolescents and children >2 years and weighing 14 kg to <25 kg.38,39 Similarly, 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 RPV40 and doravirine41—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 (TDF), TAF, zidovudine, or ABC; replacing PIs with NNRTIs), including improved lipid profiles.42-46 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.40 Additionally, studies in adults have shown improved tolerability, lipid profiles, and insulin sensitivity in patients who were switched from PIs to INSTIs,47-51 and adults who were switched from EFV to an INSTI have shown improvement in neuropsychiatric symptoms. One study in South Africa showed that prevalence of hepatic steatosis decreased from 17% to 3% among 30 adolescents who switched to a DTG-containing regimen but increased from 8% to 16% among 38 adolescents who continued a non-DTG-containing regimen. Additionally, cholesterol and triglycerides were lower in those who switched to DTG and in whom no excess weight gain was observed.52 In other studies, 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.53-57 Finally, NRTI-sparing regimens, including the dual-drug oral regimens (DRV and an INSTI or DTG/RPV) and the approved long-acting injectable regimen (CAB with RPV) described above, may be considered in patients with NRTI toxicity who otherwise are eligible for these complete ARV regimens. In a small subgroup analysis of the SWORD study, participants switched to DTG/RPV experienced small but statistically significant improvement in bone mineral density and bone turnover markers compared with those who continued on TDF.58 Of note, however, is that, although small in number, more participant adverse events that led to discontinuation were reported in the DTG/RPV arm (3%) than in the arm in which participants stayed on their current regimen (<1%).20

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, atazanavir/ritonavir)59,60 and monotherapy regimens of DTG61,62 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.60,63-66

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.). 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.67-71 The evidence that supports many of these ARV changes is indirect (i.e., 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.

Table 18. Examples of Changes in Antiretroviral Regimen Components for Children with Sustained Virologic Suppression

This list is not exhaustive and does not necessarily contain all potential treatment options. Instead, it provides examples of changes that could be made. The table includes information only about switching between ARV drugs; it does not include all the information that clinicians should consider before prescribing these drugs, such as drug cost and the patient’s insurance coverage. Refer to the individual drug sections; Appendix A, Table 1. Antiretrovirals Available in Fixed-Dose Combination Tablets or as a Co-Packaged Formulation, by Drug Class; and Appendix A, Table 2. Antiretroviral Fixed-Dose Combination Tablets and Co-packaged Formulations: Minimum Body Weights and Considerations for Use in Children and Adolescents in Appendix A. Pediatric Antiretroviral Drug Information for further information about the use and administration of specific ARV drugs and FDC formulations.

For images of most of the ARV drugs listed in this table, see the Antiretroviral Medications section of the National HIV Curriculum. In addition, a resource from the United Kingdom illustrates the relative sizes of individual ARV drug FDC tablets (see the ARV Chart in HIV i-Base). Although most of the drugs listed in that chart are the same as those in the United States, not all formulations available in the United States are included, and there are differences in a few of the brand names.

CAB and RPV co‑packaged regimen as CabenuvaLong-acting injectable, complete ARV regimen requiring two IM injections every 1 to 2 months that together are an alternative to daily oral ARV regimens. Must consider prior history of treatment failure and known or suspected drug resistance to individual drugs. Injection site reactions are common but do not often result in discontinuation of the regimen. See Cabotegravir.

Aged ≥12 years

Weighing ≥35 kg

FTC/RPV/TAF (Odefsey)Once-daily dosing. Single pill. Aligns a child’s regimen with an efficacious regimen that is used in adults. Review NNRTI mutations and check for drug–drug interactions before use. Must be taken with food at a consistent time daily.

Aged ≥12 years

Weighing ≥35 kg

SMR 4 or 5

FTC/RPV/TDF (Complera)Once-daily dosing. Single pill. Aligns a child’s regimen with an efficacious regimen that is used in adults. Review NNRTI mutations and check for drug–drug interactions before use. Must be taken with food at a consistent time daily. Renal and bone toxicity of TDF limit its use.

Aged ≥12 years

Weighing ≥25 kg

DTG/3TC (Dovato)Once-daily, two-drug complete regimen approved in adolescents and adults with no known mutations associated with resistance to the individual components who are either ART-naive or who are virologically suppressed on a stable ART regimen with no history of treatment failure. Because adolescents may have difficulties adhering to therapy, close monitoring with viral load testing is recommended.
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 5. 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 in those aged ≥3 months. 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 twice daily 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.

DTG/3TC (Dovato)Once-daily, two-drug complete regimen approved in adolescents and adults with no known mutations associated with resistance to the individual components who are either ART-naive or who are virologically suppressed on a stable ART regimen with no history of treatment failure. Because adolescents may have difficulties adhering to therapy, close monitoring with viral load testing is recommended.
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 5. 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 in those aged ≥3 months.. 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 twice daily 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.
