General information about the trial
|
|||
Main objective of the trial |
Efficacy in virological suppression assessed with standard plasma HIV-1 RNA detection (limit of detection 37 copies/mL).
|
||
Protection of trial subjects |
Informed consent was obtained from all participants to ensure they understood the study's risks and benefits. A Data and Safety Monitoring Board (DSMB) periodically reviewed the study data for safety and efficacy. Comprehensive clinical assessments and regular laboratory tests were conducted at follow-up visits. Adverse events were monitored and reported promptly. Virological monitoring and treatment adherence assessments were performed to ensure participant well-being.
