Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Recruitment took place from Mar-2010 till Sept-2011 at 37 sites in Argentina, Australia, Chile, UK, France, Hong Kong, India, Israel, Malaysia, Mexico, Peru, Nigeria, Singapore, South Africa, and Thailand. The sites had to be clinical facilities with a cohort of suitable patients and able to do protocol-mandated procedures.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
558 participants were enrolled in the study. 14 were excluded because of unverifiable data at one site and 3 dropped out before analysis, never received study treatment

Reporting Groups
  Description
Ritonavir-boosted Lopinavir and 2N(t)RTI This is the current standard of care for second line therapy following failure of standard first-line NNRTI+2N(t)RTIs according to WHO guidelines.
Ritonavir-boosted Lopinavir and Raltegravir This is an experimental arm which is likely to be fully active in the presence of N(t)RTI mutations and which preliminary evidence suggests should be potent and durable.
