A Randomised Trial of Monitoring Practice and Induction Maintenance Drug Regimens in the Management of Antiretroviral Therapy in Children With HIV Infection in Africa
In Brief
A Phase 4 clinical trial evaluating Clinically Driven Monitoring (CDM), Laboratory plus Clinical Monitoring (LCM), and 7 other interventions for Human Immunodeficiency Virus. Completed, enrolled 1,206 participants across 4 sites in 2 countries.
Detailed Summary
The two original objectives were to determine in HIV-infected children initiating antiretroviral therapy (ART): 1. Whether clinically driven monitoring (CDM) will have a similar outcome in terms of disease progression or death as routine laboratory and clinical monitoring (LCM) for toxicity (haematology/biochemistry) and efficacy (CD4)? 2. Whether induction with four drugs from two ART classes followed by maintenance with three drugs after 36 weeks be more effective than a continuous non-nucleoside reverse transcriptase inhibitors (NNRTI)-based triple drug regimen in terms of CD4 and clinical outcome? Two secondary objectives were to determine 3. Whether changing from twice daily lamivudine+abacavir to once daily lamivudine+abacavir after 48 weeks on ART will have a similar outcome in terms of virological suppression and will result in improvements in adherence to ART? 4. Whether stopping daily cotrimoxazole prophylaxis in children over 3 years of age who have been on ART for at least 96 weeks has a similar outcome in terms of hospitalisation or death as continuing daily cotrimoxazole?

Timeline
Interventions
Participants were examined by a doctor and had routine full blood count with white cell differential, lymphocyte subsets (CD4, CD8), biochemistry tests (bilirubin, urea, creatinine, aspartate aminotransferase, alanine aminotransferase) at screening, randomisation (lymphocytes only), weeks 4, 8, and 12, then every 12 weeks. Screening results were used to assess eligibility. All subsequent results at and after randomisation were only returned if requested for clinical management (authorised by centre project leaders); haemoglobin results at week 8 were automatically returned on the basis of early anaemia in a previous adult trial as were grade 4 laboratory toxicities (protocol safety criteria). Total lymphocytes and CD4 tests were never returned for CDM participants, but for all children other investigations (including tests from the routine panels) could be requested and concomitant drugs prescribed, as clinically indicated at extra patient-initiated or scheduled visits.

Children received a standard WHO-recommended regimen of open-label lamivudine, abacavir, plus NNRTI continuously. The NNRTI (nevirapine or efavirenz) was chosen by clinicians according to local availability and age.
Children initiated ART using an induction-maintenance approach, starting with open-label four-drug lamivudine, abacavir, NNRTI, plus zidovudine for 36 weeks, then open-label lamivudine, abacavir, plus NNRTI subsequently. The NNRTI (nevirapine or efavirenz) was chosen by clinicians according to local availability and age.
