Phase IV, a Clinical Trial to Assess Safety and Convenience of the Change From DTG/3TC to BIC/FTC/TAF in People With HIV, Good Virological Control and Neuropsychiatric Vulnerabilities

The clinical trial is designed to compare people with HIV and neuropsychiatric vulnerabilities, the safety and tolerability of switch to BIC/FTC/TAF versus continue on DTG/3TC.

The study includes the inclusion of 80 participants with HIV and who present among their personal history any of those established among the selection criteria (insomnia, anxiety or depression), agree to participate in the same The participants, after signing the informed consent and verifying the meeting of the selection criteria, they will be randomized to continue for 48 weeks with DTG/3TC + BIC/FTC/TAF placebo (arm 1) or switch to BIC/FTC/TAF + placebo DTG/3TC (arm 2).

All participants, except those who discontinue the study early, must to complete the same schedule of visits. It will be cause of early discontinuation loss to follow-up, withdrawal of consent, or development of any condition that requires discontinuation or change of assigned treatment.

During follow-up, the management of the basic neuropsychiatric pathology of each participant will be performed in accordance with normal clinical practice. In no case, the beginning, the change or the cessation of any pharmacological treatment or neuropsychiatric intervention should be affected by their participation in the study. If the situation arises where any participant developed a severe neuropsychiatric adverse effect (grade 3-4), two specialists in psychiatry experts in the management of patients with HIV would be responsible for evaluating them through the review of their medical history and an interview with the participant in person or via telematics. This evaluation will aim to confirm the relevance of the continuity of the patient in the study and the need for further preferential evaluation by psychiatry.
