The Antiretroviral Speed Access Program Switch (ASAP-Switch) Study
- Conditions
- HIV Infections
- Interventions
- Drug: B/F/TAF
- Registration Number
- NCT06375304
- Lead Sponsor
- McGill University Health Centre/Research Institute of the McGill University Health Centre
- Brief Summary
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).
- Detailed Description
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.

Group Intervention Description Antiretroviral Speed Access Program Switch B/F/TAF 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.
- Primary Outcome Measures
Name Time Method Feasibility of the switch 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 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 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 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 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.
- Secondary Outcome Measures
Name Time Method ART initiation (HIV care cascade milestones) From enrolment to baseline. o Treatment (ART) initiation: Proportion and/or time in days to attaining (or maintaining, as relevant).
Viral suppression (HIV care cascade milestones) From enrolment to week 72 or until viral suppression happens (whichever comes first). o Viral suppression (HIV viral load \< 50 copies/mL): Proportion and/or time in days to attaining (or maintaining, as relevant)
Retention in HIV care (HIV care cascade milestones) From enrolment to week 48. o Retention in HIV care (i.e., at least 1 clinic visit with a physician per 6-month period of study participation; i.e., a minimum of two visits in total including one within the first 6 months and one within the last 6 months of the first 12 months of the study, with a buffer time period of +/- 6 weeks).
consultations at the study site (Nature of clinical pathways) From enrolment to week 72. o Occurrence and frequency of consultations with healthcare professionals from different disciplines (e.g., physician, pharmacist, nurse, social worker, psychologist, psychiatrist) at the study site.
consultations at other care centres or organizations (Nature of clinical pathways) From enrolment to week 72. o Self-reported occurrence and frequency of consultations at other care centres or organizations.
healthcare coverage From enrolment to week 72. Identification and changes of the type of medical coverage for HIV received by participants as mentioned on patient health records. For example, a change in healthcare coverage from the Interim Federal Health Program to the Régie de l'assurance maladie du Québec (RAMQ), along with the percentages of coverage for the participants' treatment will be noted and recorded by the investigators.
