简要总结
This project builds on our experience with the ASAP Study (McGill University Health Centre research ethics board: MP-37-2020-4911). The goal of this study is to better understand the experience of migrant people with Human Immunodeficiency Virus (HIV) of having their treatment switched to Bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF). In other words, the investigators want to evaluate how feasible and acceptable this switch is, and how participants will take B/F/TAF (fidelity) and remain on it. The investigators also want to know more about migrant people with HIV's experience of care; namely, how often they see their HIV specialist or other healthcare professionals, and their healthcare coverage (the type of insurance that they have).
详细描述
International migrants represent an increasing portion of people with HIV in Canada. Making sure migrant people with HIV have access to treatment and care is crucial for their health and wellbeing. It is also important to make sure that they have a good experience of care and treatment. Several treatments exist for HIV, and many migrant people with HIV arrive in Quebec with a current or past experience of taking an HIV treatment. Sometimes, it is a treatment that cannot be continued here, for different reasons. Thus, their treatment must be 'switched', that is, changed to another treatment more affordable, simpler, or more efficient.
B/F/TAF is one HIV treatment. B/F/TAF is simple to take (one small-sized pill a day), safe, highly effective for almost all people with HIV, and ideal when one switches from one treatment to another. If participants take part in this study, their treatment will be switched to B/F/TAF; it will be provided free of charge for the participants.

- •Patients at their first visits ever at the study site;
- •Born outside of Canada, and arrived in the province of Quebec from another province or country to reside temporarily or permanently in the last 24 months;
- •ART-experienced, that is, with past or current experience of taking ART to treat HIV, with or without treatment interruption(s) for any clinical or personal reason;
- •Individuals assigned female at birth may be eligible to enter and participate in the study in the following circumstances:
- •is of non-child-bearing potential defined as either post-menopausal (12 months of spontaneous amenorrhea and 45 years of age) or physically incapable of becoming pregnant with documented tubal ligation, hysterectomy, or bilateral oophorectomy or,
- •is of child-bearing potential with a negative pregnancy test at Screening (& baseline visit) and reporting no plans to become pregnant in the next year.
- •Patients with documented historical resistance to HIV-1 reverse transcriptase inhibitors will be eligible, including: M184I/V alone or in combination with up to 2 thymidine analogue-associated mutations (TAMs) (M41L, D67N, K70R, L210W, T215F/Y, or K219Q/E/N/R).
排除标准

- •Active tuberculosis infection;
- •Acute hepatitis < 30 days before enrollment;
- •Known hypersensitivity to B/F/TAF, its metabolite or formulation excipient;
- •Documented or suspected resistance to integrase inhibitors as per clinical judgment (e.g., history of poor adherence and/or poor virological control on an InSTI-based regimen);
- •Documented multi-NRTI resistance mutations/substitutions: K65R/N/E, T69 insertion, or 3 or more TAMs (M41L, D67N, K70R, L210W, T215F/Y, K219E/Q);

研究组 & 干预措施
Antiretroviral Speed Access Program Switch
HIV (type 1) infected adults born outside of Canada (migrants) and recently moved to province of Quebec (less than 2 years), ART-experienced, newly referred at the study sites.
干预措施: B/F/TAF (Drug)
结局指标
主要结局
Feasibility of the switch
时间窗: within 7 days of first clinic visit
Feasibility refers to the extent to which an implementation target can be successfully used or deployed within a given setting. The investigators will measure what percentage of participants have done the switch and what percentage have not done the switch. For the rapid switch, the investigators will use a threshold of 75% achieving rapid switch (i.e., within 7 days of first clinic visit). Therefore, the investigators will report the percentage that achieved the switch within 7 days.
Acceptability
时间窗: From baseline to week 48.
Acceptability refers to the perception among implementation stakeholders that a given treatment, service, practice, or innovation is agreeable, palatable, or satisfactory. The investigators will assess the acceptability of: rapidity, the treatment being free-of-charge for patients, and the regimen choice. It will be measured with the 4-item Acceptability of Intervention Measure (AIM), using the following thresholds: * ≥M\*=4/5 for acceptability of rapid treatment; * ≥M=4/5 for acceptability of free treatment.
acceptability of the regimen
时间窗: From baseline to week 48.
After initiation, acceptability of the regimen choice will be assessed using the ACCEptance by the Patients of their Treatment (ACCEPT©) questionnaire, including the 3-item 'General acceptance' subscale and the 5-item 'Acceptability of side effects' subscale: • ≥M=4/5 for acceptability of the new ART regimen (in general and concerning its side effects). The response options range from 1 = "completely disagree" (worst or least acceptable) to 5 = "completely agree" (best or most acceptable).
Acceptability of the intervention
时间窗: From baseline to week 48.
Acceptability of the intervention as a whole will also be assessed in terms of readiness with a 2-item readiness measure and a measure of treatment self-efficacy with thresholds of: * ≥M=8/10 indicating readiness to start the new regimen (i.e., B/F/TAF); * ≥M=16/20 indicating treatment self-efficacy. * M: Mean or average. The responses are on a scale from 0 to 10 (10 being the best or most acceptable).
Fidelity
时间窗: From enrolment to week 72.
Fidelity concerns the degree to which a program is delivered as intended. It will be evaluated with thresholds of: • ≥80% for study visit attendance; ≥90% for self-reported regimen adherence in the past 30 days and in the last 7 days.

- ART initiation (HIV care cascade milestones)(From enrolment to baseline.)
