CORK, Ireland, February 23, 2016 /PRNewswire/ --
Intramuscular 2-drug maintenance therapy demonstrates comparable antiviral activity to
daily oral 3-drug combination
Janssen Sciences Ireland UC, one of the Janssen Pharmaceutical Companies of Johnson & Johnson, (Janssen) announced 32-week data from an ongoing phase IIb study. A regimen of two investigational long acting, intramuscular (IM) formulations of HIV medicines-Janssen's rilpivirine and ViiV Healthcare's cabotegravir-given together every 4 or 8 weeks-show comparable antiviral activity to 3-drug oral antiretroviral therapy (ART) (investigational cabotegravir and two nucleoside reverse transcriptase inhibitors (NRTIs). The full results of the study, named LATTE-2, co-funded by Janssen and ViiV Healthcare were presented at this year's Conference on Retroviruses and Opportunistic Infections (CROI) in Boston, Massachusetts today.

The LATTE-2 study is investigating the safety and efficacy of 2-drug IM ART, relative to 3-drug oral ART when used to maintain viral suppression in HIV-1 infected adults.[1]
Virologic responses (plasma HIV-1 RNA <50 c/ml by FDA snapshot analysis) for 309 patients at 32 weeks receiving two drug maintenance therapy with investigational long acting cabotegravir (CAB LA) and long acting rilpivirine (RPV LA) whether dosed every 8 weeks (Q8W, 95%) or every 4 weeks (Q4W, 94%) were comparable to the response observed in patients continuing with a three-drug oral regimen of investigational CAB + NRTIs (91%). Patients switching to CAB LA and RPV LA administered Q4W reported more adverse events (AEs) leading to withdrawal (5%; n=6) compared with those receiving an injection Q8W (2%; n=2) or those who continued on oral CAB + NRTIs (2%, n=1). The most common AE reported by patients was injection site pain (92% of injection recipients).[1]
LATTE-2 (31LB) is a phase IIb, multicentre, parallel group, and open-label study which recruited ART-naive HIV-infected adults. Enrolled patients who had a plasma HIV-1 RNA, <50 c/ml during 20-week Induction Period (IP) with daily oral CAB 30 mg + ABC/3TC were randomised 2:2:1 to IM CAB LA + RPV LA every four weeks, every 8 weeks, or remained on oral CAB + ABC/3TC (PO) in the Maintenance Period (MP). The primary endpoints evaluated antiviral activity by FDA snapshot algorithm, protocol defined virologic failure, and safety at 32 weeks in the MP.[1]
If successfully developed and approved by regulatory authorities, this regimen could offer adult patients living with and treated for HIV an option to maintain viral suppression with 6 or 12 long acting injections of each drug per year.
"Through scientific advances, over the past two decades, HIV has moved from a death sentence to a manageable chronic disease," says Wim Parys, M.D., Vice President and Head of Research and Development Global Public Health, Janssen. "Results of the LATTE-2 study show that long acting injectable drug formulations may offer an important option for HIV maintenance therapy and we remain committed to developing such combinations as we enter phase 3 studies."
Driven by a purpose of caring, and remaining committed to the prevention, detection, education and treatment of HIV, Janssen has a long history in the global battle against HIV/AIDS. It is estimated that around 37 million people are currently living with HIV globally, with 2 million people becoming newly infected each year[2]. As a company, Janssen has a deep commitment to HIV and the company's ultimate goal is to help all those living with the virus to achieve an undetectable viral load and have an improved quality of life with the aim of making HIV history.
About EDURANT(R) (Rilpivirine)
EDURANT(R) (rilpivirine) is a prescription HIV medicine that is used with other antiretroviral medicines to treat Human Immunodeficiency Virus-1 (HIV-1) in patients:
- Who have never taken HIV medicines before, and
- Who have an amount of HIV in their blood (called "viral load") that is no more than
100,000 copies/mL. Your healthcare professional will measure your viral load
EDURANT(R) should be taken in combination with other HIV medicines. Your healthcare professional will work with you to find the right combination of HIV medicines.
It is important that you remain under the care of your healthcare professional during treatment with EDURANT(R).
EDURANT(R) is not recommended for patients less than 12 years of age
EDURANT(R) does not cure HIV infection or AIDS. You should remain on your HIV medications without stopping to ensure that you control your HIV infection and decrease the risk of HIV-related illnesses. Ask your healthcare professional about how to prevent passing HIV to other people.
Please read Important Safety Information [http://www.edurant.com/patients/important-safety-information ], and talk to your healthcare professional to learn if EDURANT(R) is right for you.
About cabotegravir
Cabotegravir is an investigational integrase strand inhibitor (INSTI) and analogue of dolutegravir (TIVICAY(R)). Cabotegravir is being developed by ViiV Healthcare for the treatment and prevention of HIV and is currently being evaluated as a once-daily oral tablet formulation and as a LA nanosuspension formulation for intramuscular (IM) injection.
