The current study proposal is an open label observational trial for maintenance of virologic suppression, and is designed as a non- inferiority switch trial. The study will involve approximately 30 patients, which includes a PK arm of approximately 10 patients. The study will also include secondary outcomes of quality of life (QOL) and weight changes
Hypothesis:
Patients with prior NUC or NNRTI resistance (but not to rilpivirine or doravirine) will maintain their virologic suppression after a drug regimen switch from rilpivirine/emtricitabine/tenofovir alafenamide in combination with dolutegravir, to bictegravir/emtricitabine/tenofovir alafenamide in combination with doravirine. The switch therapy will avoid food interactions, and will be well tolerated by subjects.

Drug: Bictegravir/emtricitabine/tenofovir alafenamide + Doravirine switch
Safety and efficacy of switching from rilpivirine/emtricitabine/tenofovir alafenamide in combination with dolutegravir, to bictegravir/emtricitabine/tenofovir alafenamide in combination with doravirine in male, 45+ year old subjects. The study will also include secondary outcomes of quality of life (QOL) and weight changes.
Other Name: Biktarvy + Pifeltro Switch |
- Viral Suppression [ Time Frame: 48 Weeks ]Percentage of patients with viral HIV load (VL) <50 and <200 copies/mL at 48 weeks
- Tolerability of study drug [ Time Frame: Week 48 ]Tolerability of study drugs will be assessed by summarizing the number of AE/SAEs occurring during the study
- Change in Body Mass Index [ Time Frame: Week 48 ]Assess changes in BMI due to treatment switch
- Work Productivity and Activity [ Time Frame: Week 48 ]Improvement in work productivity and activity as measured by Work Productivity and Activity Impairment Questionnaire (WPAI)
- PK Assessment [ Time Frame: Week 4 (+/- 14 days) with time points at predose (-0.5 hr), 0.5, 1, 2, 4, 6, 8, 12, and 24 hours ]Subject plasma concentration-time data of bictegravir and doravirine will be analyzed using non-compartmental model (WinNonlin®)
- Adverse Events Assessment [ Time Frame: Day 28, Weeks 12, 24, 36, & 48 ]Assess AE's of any grade and relationship to the drug combination occurring in at least 5% of participants or more.
- Wellbeing Improvement [ Time Frame: Week 48 ]Improvement in well-being and sleep inventory as measured by The Pittsburgh Sleep Quality Index (PSQI). Minimum score is 0 and maximum score is 21. A higher score indicates worse quality sleep.
