Regimen Switch to Dolutegravir + Rilpivirine From Current Antiretroviral Regimen in Human Immunodeficiency Virus Type 1 Infected and Virologically Suppressed Adults (SWORD-2)

A Phase III, Randomized, Multicenter, Parallel-group, Non-inferiority Study Evaluating the Efficacy, Safety, and Tolerability of Switching to Dolutegravir Plus Rilpivirine From Current INI-, NNRTI-, or PI-based Antiretroviral Regimen in HIV-1-infected Adults Who Are Virologically Suppressed

Summary

The aim of this study was to determine if virologically suppressed, human immunodeficiency virus type 1 (HIV-1) infected adults on an antiretroviral regimen (including 2 nucleoside reverse transcriptase inhibitors \[NRTIs\] plus a third agent) remain suppressed upon switching to a two-drug regimen with dolutegravir (DTG) + rilpivirine (RPV). The study primarily assessed the non-inferiority antiviral activity of switching to DTG + RPV once daily compared to the continuation of current antiretroviral regimen (CAR) up to Week 48 with a switch visit for eligible subjects in the CAR group to initiate DTG + RPV therapy at Week 52. CAR included 2 NRTIs plus 1 HIV-1 integrase inhibitor (INI), or 1 non-nucleoside reverse transcriptase inhibitor (NNRTI), or 1 protease inhibitor (PI). The study included a 148-week open-label treatment phase, comprising of an Early Switch Phase (Day 1 to Week 52) and a Late Switch Phase (Week 52 to Week 148). The participants fulfilling the study eligibility criteria participated in the Early Switch Phase where they either switched from their CAR to DTG + RPV, or continued taking their CAR, until Week 52. At the end of Early Switch Phase, eligible participants proceeded to the Late Switch Phase where all participants in both DTG + RPV and CAR treatment groups received DTG + RPV therapy until Week 148. After Week 148, subjects could have been eligible to continue to receive DTG +RPV in the Continuation Phase.

Interventions

Type	Name	Description
DRUG	DTG 50 mg	Participants received one oral tablet of 50 mg DTG daily administered concomitantly with RPV. Each DTG tablet contained 52.62 mg dolutegravir sodium salt, which was equivalent to 50 mg dolutegravir free acid.
DRUG	RPV 25 mg	Participants received DTG 50 milligrams (mg) + RPV 25 mg together once daily at approximately the same time, with a meal, in an open-label fashion up to Week 52 during early switch phase. Participants continued to receive DTG 50 mg + RPV 25 mg up to Week 148 during the Late Switch Phase. Participants who successfully completed 148 weeks of treatment were given the opportunity to continue to receive DTG + RPV once daily in the Continuation Phase (after Week 148), one oral tablet of 25 mg RPV daily administered concomitantly with DTG along with a meal. Each RPV tablet contained 27.5 mg of rilpivirine hydrochloride, which was equivalent to 25 mg of RPV.
DRUG	CAR	CAR included the following combinations: 2 NRTIs + 1 INI, 2 NRTIs + 1 NNRTI, or 2 NRTIs + 1 PI.
