Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
These three groups of participants with HIV-1 infection were at first registered as three different studies: KAL1RO (this study, NCT01083810, n=137), KAL2RO /KAL5RO (NCT01083836, n=92), and KAL6RO (NCT01081470, n=55) but were now reconciled under KAL1RO (NCT01083810) as a single study with three reporting groups.

Reporting Groups
  Description
Therapy-naive Participants who had not received prior antiretroviral drug therapy.

  Serious Adverse Events


  Other Adverse Events
  Hide Other Adverse Events

Time Frame Investigators were instructed to report adverse events throughout the study (up to 5 years).
Additional Description Three studies in different populations of participants with HIV-1 infection were conducted in parallel: KAL1RO (NCT01083810, n=137), KAL2RO /KAL5RO (NCT01083836, n=92), and KAL6RO (NCT01081470, n=55). Safety data were collected in a manner that prevented separate analyses for each study, therefore pooled safety data (n=284) are shown.
