Regimen is based on co-administration of REKAMBYS® (rilpivirine injection) and ViiV Healthcare’s VOCABRIA® (cabotegravir injection) once every month or once every 2-months to treat HIV-1

Long-acting, two-drug regimen reduces treatment intake days from 365 to either 12 or six per year

BEERSE, Belgium I October 16, 2020 I The Janssen Pharmaceutical Companies of Johnson & Johnson today announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has issued a positive opinion recommending Marketing Authorisation for REKAMBYS® (rilpivirine injection) in combination with ViiV Healthcare’s VOCABRIA® (cabotegravir injection), for the treatment of Human Immunodeficiency Virus type 1 (HIV-1) infection in adults. If approved, this will be the first complete long-acting regimen, dosed once-monthly or once every-2-months, for virologically suppressed people living with HIV-1 across the European Economic Area.

”HIV remains one of the greatest global health threats of our time, so approval of the first once-monthly or once every-2-month injectable treatment regimen would mark an important step forward in the fight against this disease,” said Paul Stoffels, M.D., Vice Chairman of the Executive Committee, Chief Scientific Officer, Johnson & Johnson. “At Janssen, we are dedicated to changing the course of the HIV epidemic through our relentless pursuit of improved therapies and preventive solutions. If approved by the European Commission, this two-drug, long-acting regimen could mean patients living with HIV, no longer need daily therapy, maintaining viral load suppression with just 12 or six injection days a year.”

The CHMP positive opinion is for co-administration of rilpivirine and cabotegravir injections for the treatment of HIV-1 infection in adults who are virologically suppressed (HIV-1 RNA less than 50 copies/mL) and are on a stable antiretroviral regimen without present or past evidence of viral resistance or prior virological failure with agents of the non-nucleoside reverse transcriptase inhibitor (NNRTI) and integrase inhibitor (INI) class. The CHMP opinion also included Janssen’s EDURANT® (rilpivirine tablets) together with cabotegravir oral tablets for use as lead-in therapy for one month prior to the commencement of the long-acting injection regimen.

The EU-Marketing Authorisation Application (MAA) for rilpivirine long-acting injections is based on the pivotal Phase 3 ATLAS (Antiretroviral Therapy as Long-Acting Suppression), FLAIR (First Long-Acting Injectable Regimen) and ATLAS-2M studies. The ATLAS and FLAIR studies included more than 1,100 participants from 16 countries.1,2 The studies demonstrated that rilpivirine and cabotegravir, when injected intramuscularly once monthly, was as effective as continuing daily, oral, antiretroviral regimens in maintaining viral suppression throughout the 48-week study period.1,2

In both studies, the most common adverse reactions (Grades 1 to 4) observed in ≥2% of participants receiving rilpivirine and cabotegravir were injection site reactions, pyrexia, fatigue, headache, musculoskeletal pain, nausea, sleep disorders, dizziness, rash, and diarrhoea.3 Over the 48-week study period, a total of 4% of participants discontinued rilpivirine and cabotegravir due to adverse events.3

The EU-MAA included 48-week data from the pivotal ATLAS-2M study to support the use of rilpivirine injections once every-2-months. Results from the study showed the antiviral activity and safety of long-acting rilpivirine and cabotegravir injections administered once every-2-months was non-inferior to a once-monthly administration in virologically suppressed adults living with HIV-1 infection over a 48-week period.4 In the ATLAS-2M study rates of serious adverse events (SAEs) (27/522 [5.2%]) and withdrawals due to adverse events (AEs) (12/522 [2.3%]) at 48 weeks were low and were similar to those experienced in the one month arm (SAEs: 19/523 [3.6%], withdrawals due to AEs 13/523 [2.5%]). The most common AEs were similar between once every-2-months and once a month injections.5

At Janssen we are dedicated to driving innovation across the whole continuum of HIV care, through education, prevention, detection and treatment. We believe we have a responsibility to advance our knowledge and capabilities to address all aspects of the HIV epidemic and are deeply committed to the millions of people living with or at-risk of HIV. We are optimistic about the future – we have changed the face of HIV, and we can change it again. The long-acting regimen has been co-developed as part of a collaboration with ViiV Healthcare.

The CHMP positive opinion is one of the final steps before marketing authorisation is granted by the European Commission, which has the authority to approve medicines for use throughout the European Economic Area.

In July, Janssen resubmitted the New Drug Application (NDA) for once-monthly dosing of rilpivirine and cabotegravir to the US Food and Drug Administration (FDA). Further regulatory applications have been submitted and are being reviewed by other regulatory bodies worldwide.

About ATLAS (NCT02951052)

ATLAS is a Phase 3, open-label, active-controlled, multi-centre, parallel-group, non-inferiority study designed to assess the antiviral activity and safety of a two-drug regimen of LA, injectable rilpivirine and cabotegravir dosed every four weeks compared to continuation of current oral anti-retroviral therapy (ART) of two nucleoside reverse transcriptase inhibitors (NRTIs) plus an integrase strand transfer inhibitor (INI), non-nucleoside reverse transcriptase inhibitor (NNRTI), or protease inhibitor (PI) among virally suppressed individuals.6 The primary endpoint for ATLAS is the proportion of participants with plasma HIV-1 RNA ≥50 c/mL per the FDA Snapshot algorithm at Week 48 (missing, switch, or discontinuation = failure, intent-to-treat exposed [ITT-E] population). Participants were required to be virally suppressed for six months or longer, on a first or second regimen, with no prior failure.6

About ATLAS-2M (NCT03299049)

The ATLAS-2M study is a Phase 3, 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-1.7 Participants were required to be virologically 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-1 RNA ≥50c/mL at Week 48 using the FDA Snapshot algorithm (Intent-to-Treat Exposed [ITT-E] population).1,7

ATLAS-2M is being conducted at research centres in Australia, Argentina, Canada, France, Germany, Italy, Mexico, Russia, South Africa, South Korea, Spain, Sweden and the United States.
