Brief Summary
A new anti-HIV medicine (Dolutegravir) combined with 2 currently used anti-HIV medicines is non-inferior to the standard combination of medicines used in terms of efficacy and better in terms of toxicity.

Outcome Measures
Primary Outcomes (1)
Difference in Proportion With Failure (Clinical or Virological)
Treatment failure by 96 weeks. Estimated using time to the first occurrence of any of the following components: * Insufficient virological response defined as \< 1 log10 drop at week 24 and switch to second/third line ART for treatment failure * Viral Load (VL)\>400 c/ml at or after 36 weeks confirmed by next visit * Death due to any cause * Any new or recurrent AIDS defining event (WHO 4) or severe WHO 3 events, adjudicated by the Endpoint Review Committee
96 weeks post randomisation
Secondary Outcomes (25)

Serious Adverse Events
Randomised phase: follow-up was censored when the last participant reached 96 weeks of follow-up (142 weeks (IQR:124 to 159) in ≥14kg cohort and 124 weeks (112 to 137) in <14kg cohort).

Interventions
Eligibility Criteria
You may qualify if:
- ALL PATIENTS:
- Children ≥28 days and \<18 years weighing ≥3kg with confirmed HIV-1 infection
- Parents/carers and children, where applicable, give informed written consent
- Girls aged 12 years or older who have reached menses must have a negative pregnancy test at screening and be willing to adhere to effective methods of contraception if sexually active
- Children with co-infections who need to start ART can be enrolled into ODYSSEY according to local/national guidelines
- Parents/carers and children, where applicable, willing to adhere to a minimum of 96 weeks' follow-up
- Children weighing 3 to \<14kg must be eligible and willing to participate in the Weight band (WB)-Pharmacokinetics (PK)1 substudy unless direct enrolment for the child's weight band has opened following the WB-PK1 substudy and/or dosing information has become available from the IMPAACT P1093 DTG dose-finding study.
- ADDITIONAL CRITERIA FOR ODYSSEY A:
- Planning to start first-line ART
- ADDITIONAL CRITERIA FOR ODYSSEY B:
- Planning to start second-line ART defined as either: (i) switch of at least 2 ART drugs due to treatment failure; or (ii) switch of only the third agent due to treatment failure where drug sensitivity tests show no mutations conferring Nucleoside Reverse Transcriptase Inhibitor (NRTI) resistance
- Treated with only one previous ART regimen. Single drug substitutions for toxicity, simplification, changes in national guidelines or drug availability are allowed
- At least one NRTI with predicted preserved activity available for a background regimen
- In settings where resistance tests are routinely available, at least one new active NRTI from tenofovir disoproxil fumarate, abacavir or zidovudine should have preserved activity based on cumulative results of resistance tests
- In settings where resistance tests are not routinely available, children who are due to switch according to national guidelines should have at least one new NRTI predicted to be available from tenofovir disoproxil fumarate, abacavir or zidovudine
- +1 more criteria
You may not qualify if:
- History or presence of known allergy or contraindications to dolutegravir
- History or presence of known allergy or contraindications to proposed available NRTI backbone or proposed available SOC third agent.
- Alanine aminotransferase (ALT) ≥ 5 times the upper limit of normal, OR ALT ≥3x upper limit of normal and bilirubin ≥2x upper limit of normal
- Patients with severe hepatic impairment or unstable liver disease (as defined by the presence of ascites, encephalopathy, coagulopathy, hypoalbuminaemia, oesophageal or gastric varices, or persistent jaundice), known biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones)
- Anticipated need for Hepatitis C virus (HCV) therapy during the study
- Pregnancy or breastfeeding
- Evidence of lack of susceptibility to integrase inhibitors or more than a 2-week exposure to antiretrovirals of this class
