ViiV Healthcare Reports Positive Phase III Study Results of Investigational, Long-acting, Injectable HIV-Treatment Regimen Administered Every Two Months
ATLAS-2M study met its primary endpoint, showing similar efficacy of cabotegravir and rilpivirine administered every eight weeks compared to four-week administration
The study met its primary endpoint, showing that the long-acting regimen of cabotegravir and rilpivirine, injected every two months, was non-inferior to cabotegravir and rilpivirine administered every month at Week 48. Non-inferiority was assessed by comparison of the proportions of participants with plasma HIV-RNA ≥ 50 copies per milliliter (c/mL) using the FDA Snapshot algorithm at Week 48 (Intent-to-Treat Exposed [ITTE] population). Overall safety, virologic response and drug resistance results for the every-two-months injectable regimen were consistent with results from the phase III ATLAS study.
Detailed results from the ATLAS-2M study will be presented at an upcoming scientific meeting.
This investigational, long-acting, injectable regimen is being co-developed as a collaboration with Janssen Sciences Ireland UC and has been submitted to regulatory authorities in
About ATLAS-2M (NCT03299049)
The ATLAS-2M study is a phase III, randomised, open-label, active-controlled, multicentre, parallel-group, non-inferiority study designed to assess the non-inferior antiviral activity and safety of long-acting cabotegravir and rilpivirine administered every eight weeks compared to long-acting cabotegravir and rilpivirine administered every four weeks over a 48-week treatment period in 1,045 adults living with HIV-1.1 Subjects were required to be virally-suppressed for six months or greater, on first or second regimen, with no prior failure. The primary outcome measure for the study is the proportion of participants with HIV-RNA ≥ 50 c/mL at Week 48 using the FDA Snapshot algorithm (Intent-to-Treat Exposed [ITT-E] population).
ATLAS-2M is part of ViiV Healthcare’s extensive and innovative clinical trial programme for 2-drug regimens. The study is being conducted at research centres in
