Study setting(s)Not specified
Study typeTreatment
Scientific title
Study acronymPENTA 14
Study objectives1. To assess the effect of different levels of Therapeutic drug monitoring (TDM) compared with no TDM on plasma human immunodeficiency virus-1 ribonucleic acid (HIV-1 RNA) response in children starting or switching to a new highly active antiretroviral therapy (HAART) regimen including a protease inhibitor (PI) and/or non-nucleoside reverse transcriptase inhibitor (NNRTI)
2. To generate age-related population pharmacokinetic models for PIs and NNRTIs used in children
3. To describe the impact of a didactic adherence support tool for children taking HAART, which will be offered to centres participating in the trial
Ethics approval(s)Not provided at time of registration
Health condition(s) or problem(s) studiedPaediatric HIV
InterventionFull five point annual pharmacokinetic (PK) curve versus single sample PK versus no intervention. All children will receive additional adherence support.
Intervention typeOther
Primary outcome measureThe effect of the TDM strategies on viral load in terms of change in plasma HIV-1 RNA copies/ml from baseline to 96 weeks
Secondary outcome measures1. The proportion of children who ever achieve plasma HIV-1 RNA <50 copies/ml, and who subsequently maintain plasma HIV-1 RNA <50 copies/ml to 96 weeks
2. Toxicity and tolerability of HAART
3. Adherence to HAART as assessed by caregiver completed questionnaire and CORALs
4. Progression to new AIDS defining event or death
5. Number of switches in antiretroviral therapy
6. The development of new genotypic resistance mutations by 96 weeks
7. Change in CD4% and CD4 count from baseline to week 96
8. Number of children in the target area for pharmacokinetic parameters after 12 weeks
9. Number of dosage adjustments based on pharmacokinetic parameters after 48 weeks
Overall study start date01/07/2004
Completion date01/11/2007
Reason abandoned (if study stopped)Recruitment problems which were caused mainly by TDM being accepted as routine practice.

Age groupChild
Lower age limit1 Month
Upper age limit17 Years
SexBoth
Target number of participants166 (14 recruited as of September 2006)
Key inclusion criteria1. Confirmed HIV-infected, i.e. positive plasma HIV-1 RNA or deoxyribonucleic acid (DNA) test on two consecutive occasions (for children less than 18 months old), or positive HIV serology (for children aged 18 months and older), aged one month to 17 years inclusive
2. Parents/guardians, and children where appropriate, are willing and able to give informed consent
3. Plasma HIV-1 RNA viral load = 1000 copies/ml
4. Pre-treated children, including children who have received antiretroviral therapy only as prophylaxis to reduce mother to child transmission, who are prepared to wait for the results of a resistance test before starting new therapy
5. Starting antiretroviral therapy or switching to a new antiretroviral regimen considered likely to be highly active according to the results of a local resistance test, and containing either a PI or NNRTI or both; that is with at least two active drugs, one being a PI or NNRTI (active means not fully resistant)
Key exclusion criteriaGrade 3 or 4 creatinine or liver function tests
Date of first enrolment01/07/2004
