Open-Label Multi-Centre Randomised Switch Study to Evaluate Virological Efficacy Over 96Weeks Of 2-Drug Therapy With Dolutegravir(DTG)/Rilpivirine(RPV) Fixed Dose Combination(FDC) in Antiretroviral Treatment-Experienced HIV-1 Infected Subjects Virologically Suppressed With NNRTI Mutation K103N

Brief Summary

HIV-1 infected subjects that experience virological failure while on non nucleoside reverse-transcriptase inhibitors (NNRTIs), including those with the K103N mutation, are usually switched to a boosted Protease Inhibitor (PI)-based regimen or other antiretroviral (ARV) combinations. The same is true for subjects who need to start antiretroviral therapy and have acquired virus that is already resistant to antiretrovirals. These "second line" combinations are often associated with numerous issues that can have a potential impact on the quality of life (QoL) of these patients. Therefore a simpler and better tolerated alternative second line treatment option would be a useful tool for the clinical management of these patients.

The aim of this study is to assess the efficacy and tolerability of a dual combined therapy of Dolutegravir (DTG) 50 mg Once Daily (OD) + Rilpivirine (RPV) 25 mg OD in virologically suppressed participants with previous virological failure with NNRTIs and having the clinically significant mutation K103N. The secondary objective of the study is to assess whether a simplification of the treatment in terms of pill burden, long term metabolic toxicity and potential for drug interactions improves the QOL of the participants. The study will also evaluate DTG \& RPV concentrations in the blood plus changes in cell associated virus.

In order to compare the first line treatment (boosted PI and/or other antiretroviral combinations) and the DTG+RPV combination, two thirds of study participants will be switched to DTG+RPV immediately and receive DTG+RPV for 96 weeks. The other third will be switched after 48 weeks of continuing on their first line treatment and receive DTG+RPV for 48 weeks. All participants will then be followed up for a further 30 days. Participants will be recruited from sites across Europe, and randomised onto either arm of the study. After randomisation, participants will attend approximately 10 visits over the course of two years.

Questionnaire (EQ-5D-3L) Mobility, Self-care, Usual activities, Pain/Discomfort and Anxiety/Depression are recorded on 3 point scale (tick boxes), which indicates the severity of problems the participant has with each of these activities. Patients will select No problems, Some problems or Extreme problems/Unable to perform. Patients also report their current Health State on a Scale from 1 to 100 on which the best state you can imagine is marked 100 and the worst state you can imagine is marked 0.

Changes in Pittsburgh Sleep Quality Index (PSQI)Changed assessed from baseline to week 48, week 48 to week 96, baseline to week 96

The PSQI measures several different aspects of sleep, with seven component scores and one composite score. The component scores include questions on subjective sleep quality, sleep latency (i.e., how long it takes to fall asleep), sleep duration, habitual sleep efficiency (i.e., the percentage of time in bed that one is asleep), sleep disturbances, use of sleeping medication, and daytime dysfunction.

Each component score of the PSQI ranges from 0 to 3, with 3 indicating the greatest dysfunction or disturbance to sleep. The seven component scores are then summed to obtain a global PSQI score, which ranges from 0 to 21. Higher scores indicate poorer sleep quality, with a score greater than 5 suggesting significant sleep difficulties
