ATLAS and FLAIR studies presented at the 2019 Conference on Retroviruses and Opportunistic Infections met primary endpoints showing long-acting, injectable regimen to be effective in virally suppressed adults living with HIV

CORK, The Janssen Pharmaceutical Companies of Johnson & Johnson confirmed that the novel, investigational, long-acting two-drug injectable regimen of rilpivirine and cabotegravir met its primary endpoints in two major Phase 3 studies - the Antiretroviral Therapy as Long-Acting Suppression (ATLAS) trial and the First Long-Acting Injectable Regimen (FLAIR) trial. The positive 48-week results from both studies showed that Janssen's rilpivirine and ViiV Healthcare's cabotegravir, injected every four weeks, had similar efficacy in maintaining viral suppression in adults living with HIV-1 when compared to a standard of care, daily, oral three-drug regimen. These data were presented at the 2019 Conference on Retroviruses and Opportunistic Infections (CROI) in Seattle, Washington.? A livestream of the CROI press conference where these studies were highlighted can be viewed here:?https://zoom.us/j/755218010 "The Phase 3 results from these studies show that a two-drug injectable treatment regimen may provide people living with HIV the option of managing their virus with just 12 injection regimens a year. If approved by regulators, this will be the first monthly dosing solution for people living with HIV and represents a major step for HIV treatment," said?Brian Woodfall, M.D., Global Head, Development, Infectious Diseases, Janssen Pharmaceutica NV.??"At Janssen, we are committed to the ongoing research and development of innovative solutions to fight HIV across the continuum of care. Using heart, science and ingenuity, we are partnering with others and utilizing our scale with the aim to make HIV history." ATLAS The global, pivotal, Phase 3 ATLAS study met its primary endpoint, with rilpivirine? and cabotegravir (long acting, or LA regimen) demonstrating non-inferiority to an oral three-drug regimen of two nucleoside reverse transcriptase inhibitors (NRTIs) plus a third agent on viral nonresponse, as measured by the proportion of patients with plasma HIV-1 RNA =50 copies per milliliter [c/mL] using the FDA Snapshot algorithm at Week 48 [LA regimen: 5/308 (1.6 percent), current antiretroviral therapy: (CAR) 3/308 (1.0 percent), adjusted difference: 0.6 percent, 95 percent confidence interval: -1.2, 2.5)]. The study found virologic suppression rates (HIV-1 RNA <50 c/mL) at Week 48 were similar between treatment arms [LA regimen: 285/308 (92.5 percent), CAR: 294/308 (95.5 percent), adjusted difference: -3 percent, 95 percent confidence interval: -6.7, 0.7].? Confirmed virologic failure (CVF) was infrequent.? Three patients (1 percent) who received the LA regimen developed CVF with subsequent identification of resistance mutations to one or both agents.? In two of these cases, pre-existing NNRTI resistance was identified. Two of the three individuals were from?Russia?and all three had HIV-1 A subtypes, which are seen frequently in?Russia,?Eastern Europe?and?East Africa; however, they are seen infrequently in other parts of the world. This unexpected pattern warrants further investigation. In the oral CAR arm, four participants developed CVF, three of whom developed drug resistance mutations. Patient treatment satisfaction significantly improved after switching to the LA regimen from the previous oral therapy compared to remaining on oral therapy at Week 44 based on the HIV Treatment Satisfaction Questionnaire (HIVTSQs mean difference 5.68; 95 percent CI [4.37, 6.9]; p<0.001). Patient preference data from a single-item question administered at Week 48 showed that 266/308 (86.4 percent) preferred the long-acting injectable regimen whereas 7/308 (2.3 percent) preferred their previous oral therapy. "The positive safety and efficacy results from the ATLAS study reinforce the potential of rilpivirine and cabotegravir as the first long-acting, injectable regimen option for people living with HIV," said?Susan Swindells, MBBS, Professor, Department of Internal Medicine, Section of Infectious Diseases at the?University of Nebraska Medical Center?and ATLAS principal investigator.? "This novel approach may help alleviate the burden often associated with daily oral treatment regimens and contribute to making HIV a smaller part of people's lives." Treatment with the LA regimen was generally well-tolerated, with low rates of serious adverse events (SAEs) [13/308 (4.2 percent)] and drug- or injection-related withdrawals. Of the patients who received the LA regimen, 83 percent (250/308) reported an injection site reaction (ISR) at some point through the 48-week study.? A majority of injections did not result in ISRs being reported; among a total of 6978 injections administered during the 48-week study, 1460 ISRs were reported. Most ISR events were mild [1156/1460 (79.2 percent)] and lasted an average of three days.? Four participants (1.3 percent) withdrew for injection-related events. FLAIR The global, pivotal, Phase 3 study met its primary endpoint, with the LA regimen demonstrating non-inferiority to Triumeq?(abacavir/dolutegravir/lamivudine-ABC/DTG/3TC), as measured by the proportion of patients with plasma HIV-1 RNA =50 copies per milliliter [c/mL] using the FDA Snapshot algorithm at Week 48 [LA regimen: 6/283 (2.1 percent), Triumeq??7/283 (2.5 percent), adjusted difference: -0.4 percent, 95 percent confidence interval: -2.8, 2.1)].? The study found virologic suppression rates (HIV-1 RNA <50 c/mL) at Week 48 were similar between treatment arms [LA regimen: 265/283 (93.6 percent), Triumeq?: 264/283 (93.3 percent), adjusted difference: 0.4 percent. 95 percent confidence interval: -3.7, 4.5]. Confirmed virologic failure (CVF) was infrequent across both treatment arms. Of the individuals who received the LA regimen, there were three confirmed virologic failures (approximately 1 percent), all of whom had treatment-emergent, NNRTI and INSTI resistance.? All of these individuals were from?Russia?and had?HIV-1 subtype A1, which is seen frequently in?Russia,?Eastern Europe?and?East Africa; however, it is seen infrequently in other parts of the world. This unexpected pattern warrants further investigation. Three participants in the Triumeq??arm developed CVF with no treatment emergent resistance. Patient treatment satisfaction significantly improved after switching to the LA regimen from the previous oral therapy compared to remaining on oral therapy at Week 48 based on the HIV Treatment Satisfaction Questionnaire (HIVTSQc mean difference 4.1; 95 percent CI [2.8, 5.5], p<0.001). Patient preference data from a single-item question administered at Week 48 showed that 257/283 (90.8 percent) preferred the LA regimen whereas 2/283 (0.7 percent) preferred their previous oral therapy. "The robust results of the FLAIR study lend further evidence to the potential of rilpivirine and cabotegravir as an alternative option for people currently on daily, oral therapy," said?Chloe Orkin, M.D., Consultant Physician and Clinical Professor at Queen Mary University of?London?and FLAIR principal investigator. "This long-acting, two-drug regimen may provide an opportunity to change the paradigm for people living with HIV by breaking the cycle of daily pill taking, which has been a defining characteristic of HIV therapy for several decades." Treatment with the LA regimen was generally well-tolerated, with low rates of SAEs [18/283 (6.4 percent)] and adverse events (AEs) leading to withdrawal [9/283 (3.2 percent)]. Of the patients who received the LA regimen, 86 percent (239/283) reported an ISR at some point through the 48-week study. A majority of injections did not result in an ISR being reported, with a total of 7704 injections administered during the 48-week study resulting in 2203 ISR events. Nearly all ISRs (99.4 percent) were mild or moderate (mild: 1907/2203, moderate: 282/2203),?with a median duration of three days and the frequency of these events decreasing over time. Four participants (1.4 percent) withdrew for injection related events. In addition to the once-monthly dosing schedule being evaluated in the ATLAS study, a study is ongoing to investigate the LA regimen administered every two months in the ATLAS-2M study. The company plans to use data from the FLAIR and ATLAS studies for future regulatory submissions. This novel regimen is being co-developed as part of a collaboration with ViiV Healthcare.
