Patient-Reported Outcomes HIV BItherapy

Study Overview
=================
Brief Summary
-----------------
HIV Treatment simplification strategies that involve switching cART regimens from four or three antiretrovirals to two in virologically suppressed patients living with HIV are now available in order to reduce long-term toxicity and enhance treatment adherence. Dolutegravir is a second-generation integrase strand transfer inhibitor (INSTI) with noticeable advantages, including a high genetic barrier to drug resistance, once-daily dosing and lower risk of drug-drug interactions because this agent does not inhibit or induce cytochrome P450 isoenzymes or P-glycoprotein transporters. Dolutegravir is generally well tolerated and the INSTI class is considered to be more metabolically friendly compared with other drug classes such as protease inhibitors (PIs). Thus, the combination of dolutegravir plus a second active agent is a particularly inviting option for maintenance treatment and research in this area is evolving. However, though safety and efficacy of dolutegravir are well known, there is no study evaluating patient-reported outcomes (PROs), i.e. subjective and self-reported measures of the patient's health perception. In an era of the efficacy of HIV regimens are more and more comparable, the main discriminant criteria to choose the best treatment option are now adherence and self-reported measures of a patient's health - termed patient-reported outcomes (PROs). The study, based on a mixed methodology, include a qualitative part and a quantitative part. The qualitative study will explore patients' and health care professionals' perceptions, knowledge, and representations of triple or quadruple and dual therapies and detect the degree of agreement or disagreement between patients' and practitioners' perspectives. The quantitative study's main objective is to measure the Dovato regimen's impact on a patient's perception (Patient-Reported Outcomes - PRO) on acceptability, toxicity, preference, and Health-Related Quality of Life (HRQL). PRO are collected through self-administered questionnaires at D0 (when the patient switch treatment), M1 and M6.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change of the patient perception (Patient-Reported Outcomes - PRO) after a switch from HIV tritherapy to DOVATO dual therapy on the perceived toxicity of the treatment. | A score of perceived toxicity and preference: measured by the scale developed during a previous qualitative step of the study (PTP scale) on the day of the switch, 1 month after the switch and 6 month after the switch. | Day 0, Month 1 and Month 6 | 
| Change of the patient perception (Patient-Reported Outcomes - PRO) after a switch from HIV tritherapy to DOVATO dual therapy on the acceptability of the treatment. | A score of acceptability (at baseline only): measured by the scale developed during a previous qualitative step of the study (Acceptability scale) on the day of the switch, 1 month after the switch and 6 month after the switch. | Day 0, Month 1 and Month 6 | 
| Change of the patient perception (Patient-Reported Outcomes - PRO) after the switch from HIV tritherapy to DOVATO dual therapy on Health-Related Quality of Life (HRQL) | The treatment impact (TI, 10) dimension of the PROQOL-HIV questionnaire will measure HRQL on the day of the switch, 1 month after the switch and 6 month after the switch. | Day 0, Month 1 and Month 6 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change of the patient perception (Patient-Reported Outcomes - PRO) after the switch from HIV tritherapy to DOVATO dual therapy on the percieved HIV symptoms | HIV Symptom Index, a 20 items index on different symptoms experienced by HIV patients on the day of the switch, 1 month after the switch and 6 month after the switch. | Day 0, Month 1 and Month 6 | 
| Change of the patient perception (Patient-Reported Outcomes - PRO) after the switch from HIV tritherapy to DOVATO dual therapy on adherence with the dual therapy | Adherence ANRS (Agence nationale de recherches sur le sida et les hépatites virales - French agency for AIDS and viral hepatitis research) questionnaire of 3 items | Day 0, Month 1 and Month 6 | 
| Factors associated with high preference versus low preference for dual therapy | Describe the factors associated with high acceptability of Dovato regimen (acceptability scale) | Day 0, Month 1 and Month 6 | 
| Efficacy of the Dovato regimen through Week 24 | Percentage of Participants With Human Immunodeficiency Virus-1 (HIV-1) RNA <50 Copies (c)/Millilitre (mL) Through Week 24 | Day 0, Month 1 and Month 6 | 
| Kinetic of CD4 through Week 24 | Change From Baseline in Cluster of Differentiation (CD)4+ Cell Counts Over Time | Day 0, Month 1 and Month 6 |
