Can healthy volunteers participate?
No
Key exclusion criteria
• Any pre-existing physical or mental condition (including substance use disorder) which, in the opinion of the investigators, may interfere with the participant's ability to comply with the dosing schedule and/or protocol evaluations or which may compromise the safety of the participant.
• Any condition which, in the opinion of the investigator, may interfere with the absorption, distribution, metabolism or excretion of the study drugs or render the participant unable to receive study medication.
• History or presence of allergy or intolerance to the study drugs or their components or drugs of their class.
• Current or anticipated need for chronic anti-coagulation or hereditary coagulation and platelet disorders such as haemophilia or Von Willebrand Disease.
• Any past history of virological failure on NNRTI or Integrase inhibitor therapy with or without documentation of any major known Integrase inhibitor (and L74I) or NNRTI resistance-associated mutation including K103N by any historical resistance test result.
• ALT >=5 × Upper Limit Normal (ULN) or ALT >=3xULN and bilirubin >=1.5xULN (with >35% direct bilirubin) over the last 6 months.
• Any verified Grade 4 laboratory abnormality. A single repeat test is allowed during the Screening phase to verify a result.
• Participant has estimated creatinine clearance <50 mL/min/1.73meter^2 via the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation.

Statistical methods / analysis
The study size reflects the most feasible size that will ensure an adequate number of patients reflecting the diversity of background medical and social needs, and a distribution of HIV complexity scales.

The measures of adherence over all visits for each of 60 patients will be the primary outcome measures. The precision of the estimate of non-adherence will be an indicator of power, depending on rate of non-adherence. For example,
Assuming 10% non-adherence then the 95%CI in a n=60 sample is: 3.76% to 20.51%
At 5% non-adherence rate, the 95% CI around the 5% would be 1.04% to 13.92%
At 0% non-adherence, then for the one sided CI (97.5% - upper limit only) – is 0 to 5.96%

Descriptive statistics of, safety parameters including ISRs, reasons for withdrawal, numbers of re-scheduled injections, numbers of treatment breaks requiring oral bridging, numbers of visits for non-study related care or social support, will be provided including 95% confidence intervals for primary and secondary endpoints, as appropriate.

Exploratory univariate and multivariate regression analyses will be undertaken to assess the association(s) between primary and secondary endpoints including responses to the satisfaction surveys (as outcomes) and potentially predictive factors such as patients’ composite complexity rating, individual complexity factors, demographic, social and other baseline characteristics.

Summary
Brief summary
This is a single-arm, open-label study to evaluate the feasibility and effectiveness of long acting antiretroviral therapy in a "real world" setting, with inclusion of patients with complex social and medical needs and who have been under-represented in randomised clinical trials. Standard assessments of virological suppression and tolerability will be carried out however the study will primarily assess adherence to injections, qualitative aspects of the patient experience and satisfaction with injections as long-term therapy by both patients and providers, compared with patients' previously prescribed oral regimens. The study will also aim to describe the operational changes in clinical service required to deliver LA therapy and the patient and health-service characteristics associated with best outcomes.
