London, 24 July 2018 - ViiV Healthcare today presented 100-week results from its phase III programme evaluating the safety and efficacy of switching virologically-suppressed people living with HIV from a three or four-drug antiretroviral regimen to a 2-drug regimen of dolutegravir (ViiV Healthcare) and rilpivirine (Janssen Sciences Ireland UC, part of the Janssen Pharmaceutical Companies of Johnson & Johnson.)[1] These results were presented at the 22nd International AIDS Conference taking place 23-27 July 2018 in Amsterdam.
John C. Pottage, Jr., MD, Chief Scientific and Medical Officer, ViiV Healthcare, commented, "As we progress further into a new era of HIV treatment, these 100-week data from the SWORD studies add to the growing evidence base for Juluca and 2-drug regimens. The results confirm the ability of Juluca to maintain efficacy over a 100-week period and importantly support that the long-term safety profile of this regimen is consistent with the respective labels of the component medicines. This 100-week data should provide physicians with further confidence that they may be able to reduce the number of antiretroviral drugs required to effectively maintain virologic suppression in their patient's HIV."
In pooled data from the SWORD 1 and SWORD 2 studies, 89% (456/513) of participants on the 2-drug regimen of dolutegravir and rilpivirine for 100 weeks (n=513) maintained viral suppression, with a viral load of less than 50 copies/mL. A low rate of snapshot virologic non-response was observed (n=13; 3%) and 6 participants met the confirmed virologic withdrawal criterion. Three participants failed with NNRTI mutations, one that had pre-existing NNRTI mutations at baseline developed resistance to rilpivirine and was withdrawn; no participants developed integrase inhibitor resistance. There were no new safety findings in the second year of the study. A total 34 participants (7%) experienced adverse events that led to withdrawal through week 100.[1]
In the 'late switch' arm (n=477), where participants continued on their current antiretroviral regimen until week 52 before switching to the 2-drug regimen of dolutegravir and rilpivirine, 93% (n=444) of participants maintained viral suppression through week 100. Two participants (<1%) met the confirmed virologic withdrawal criterion, and the safety profile of the late switch group was comparable to the early switch group (dolutegravir and rilpivirine from day 1 to week 100). 30 participants (6%) experienced serious adverse events and 15 participants (3%) experienced adverse events that led to withdrawal.[1]
The SWORD clinical programme is part of ViiV Healthcare's ongoing commitment to lessening the burden of HIV treatment on PLHIV through research into 2-drug regimens. The 48-week results from the SWORD studies were presented at CROI 2017 and later published in The Lancet.[2]Data from the SWORD studies as well as a pivotal bioequivalence study[3] has led to successful regulatory approval of the 2-drug regimen in the United States, European Union, Canada and Australia, marketed under the trade name Juluca.[4],[5],[6],[7]

Notes to editors
About HIV
HIV stands for the Human Immunodeficiency Virus. Unlike some other viruses, the human body cannot get rid of HIV, so once someone has HIV they have it for life. There is no cure for HIV, but effective treatment can control the virus so that people with HIV can enjoy healthy and productive lives.
HIV has largely become a chronic treatable disease with improved access to antiretroviral treatment. This has led to a 22% drop in global HIV mortality between 2009 and 2013,[8] but more can be done for the estimated 36.7 million people living with HIV[9] of which 160,000 were newly diagnosed in the Europe region alone in 2016.[10]
About Juluca (dolutegravir/rilpivirine)
Juluca is ViiV Healthcare's first two-drug regimen (2DR), once-daily, single-pill that combines dolutegravir 50mg (ViiV Healthcare), the most widely prescribed integrase inhibitor (INI) worldwide, with the nucleoside reverse transcriptase inhibitor (NNRTI) rilpivirine 25mg (Janssen Sciences Ireland UC). Juluca was granted marketing authorisation by regulatory authorities in the United States in November 2017, the European Union and Canada in May 2018, and Australia in June 2018.[4],[5],[6],[7] ViiV Healthcare has also submitted regulatory marketing applications in other countries worldwide.
Juluca is indicated for the treatment of human immunodeficiency virus type 1 (HIV-1) infection in adults who are virologically suppressed (HIV-1 RNA < 50 copies/mL) on a stable antiretroviral regimen for at least six months with no history of virological failure and no known or suspected resistance to any NNRTI or INI.[4]
Two essential steps in the HIV life cycle include reverse transcription - when the virus turns its RNA (ribonucleic acid) copy into DNA (deoxyribonucleic acid) - and integration - the moment when viral DNA becomes part of the host cell's DNA. These processes require two enzymes called nucleoside reverse transcriptase and integrase. NNRTIs and INIs interfere with the action of these two enzymes to prevent the virus from replicating. This decrease in replication can lead to less virus being available to cause subsequent infection of uninfected cells.
About the SWORD phase III programme for Juluca
The SWORD phase III programme evaluates the efficacy, safety, and tolerability of switching to dolutegravir plus rilpivirine from current integrase inhibitor-, non-nucleoside reverse transcriptase inhibitor-, or boosted protease inhibitor-based antiretroviral regimen in HIV-1-infected adults who are virologically suppressed with a three or four-drug regimen.[11],[12]SWORD-1 (NCT02429791) and SWORD-2 (NCT02422797) are replicate 148-week, randomised, open-label, non-inferiority studies to assess the antiviral activity and safety of a 2-drug, daily oral regimen of dolutegravir plus rilpivirine compared with current antiretroviral therapy[11],[12] (the 148-week data will be shared in 2019). In the SWORD clinical trials, dolutegravir and rilpivirine are provided as individual tablets.[11],[12]
The primary endpoint is the proportion of patients with plasma HIV-1 RNA <50 copies per millilitre (copies/mL) at week 48. Key secondary endpoints include evaluation of the development of viral resistance, measurements of safety and tolerability, and changes in renal, bone and cardiovascular biomarkers. The studies also include exploratory measures to assess change in health-related quality of life, willingness to switch and adherence to treatment regimens.[11],[12]

U.S. IMPORTANT SAFETY INFORMATION: JULUCA (dolutegravir and rilpivirine) tablets
Professional Indication(s) and Important Safety Information
Indication and Usage for JULUCA
JULUCA is indicated as a complete regimen for the treatment of human immunodeficiency virus type 1 (HIV-1) infection in adults to replace the current antiretroviral regimen in those who are virologically suppressed (HIV-1 RNA <50 copies/mL) on a stable antiretroviral regimen for ≥6 months with no history of treatment failure and no known substitutions associated with resistance to the individual components of JULUCA.
Important Safety Information
CONTRAINDICATIONS
JULUCA is contraindicated in patients:
o with previous hypersensitivity reaction to dolutegravir or rilpivirine.
o receiving dofetilide, carbamazepine, oxcarbazepine, phenobarbital, phenytoin, rifampin, rifapentine, systemic dexamethasone (>1 dose), St. John's wort, and proton pump inhibitors (e.g., esomeprazole, lansoprazole, omeprazole, pantoprazole, and rabeprazole).
WARNINGS AND PRECAUTIONS
Skin and Hypersensitivity Reactions:
o Hypersensitivity reactions have been reported with dolutegravir and were characterized by rash, constitutional findings, and sometimes organ dysfunction, including liver injury. These events were reported in <1% of subjects receiving dolutegravir in Phase 3 clinical trials.
o Severe skin and hypersensitivity reactions have been reported during postmarketing experience, including cases of Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS), with rilpivirine-containing regimens and have been accompanied by fever and/or organ dysfunctions including elevations in hepatic serum biochemistries.
o Discontinue JULUCA immediately if signs or symptoms of severe skin or hypersensitivity reactions develop (such as severe rash or rash accompanied by fever, general malaise, fatigue, muscle or joint aches, blisters or peeling of the skin, mucosal involvement, conjunctivitis, facial edema, hepatitis, eosinophilia, angioedema, and difficulty breathing), as a delay in stopping treatment may result in a life-threatening reaction. Clinical status, including laboratory parameters with liver aminotransferases, should be monitored and appropriate therapy initiated.
Hepatotoxicity:
o Hepatic adverse events have been reported, including cases of hepatic toxicity, in patients without pre-existing hepatic disease or other identifiable risk factors.
o Patients with underlying hepatitis B or C or marked elevations in transaminases prior to treatment may be at increased risk for worsening or development of transaminase elevations. In some cases, the elevations in transaminases were consistent with immune reconstitution syndrome or hepatitis B reactivation, particularly in the setting where anti-hepatitis therapy was withdrawn.
o Monitoring for hepatotoxicity is recommended.
Depressive Disorders:
o Depressive disorders (including depressed mood, depression, dysphoria, major depression, mood altered, negative thoughts, suicide attempt, and suicidal ideation) have been reported.
o Promptly evaluate patients with severe depressive symptoms.
Risk of Adverse Reactions or Loss of Virologic Response Due to Drug Interactions:
o The concomitant use of JULUCA and other drugs may result in known or potentially significant drug interactions, see Contraindications and Drug Interactions sections. Rilpivirine doses 3 and 12 times higher than the recommended dose can prolong the QTc interval. Consider alternatives to JULUCA when coadministered with a drug with a known risk of Torsade de Pointes. Consider the potential for drug interactions prior to and during therapy with JULUCA and monitor for adverse reactions.
ADVERSE REACTIONS: Most common adverse reactions with JULUCA (incidence ≥2%, all Grades) were diarrhea (2%) and headache (2%).
DRUG INTERACTIONS
o Because JULUCA is a complete regimen, coadministration with other antiretroviral medications for the treatment of HIV-1 infection is not recommended.
o Drugs that induce or inhibit CYP3A or UGT1A1 may affect the plasma concentrations of the components of JULUCA.
o Drugs that increase gastric pH or containing polyvalent cations may decrease plasma concentrations of the components of JULUCA.
o Consider alternatives to prescribing JULUCA with drugs with a known risk of Torsade de Pointes.
o Consult the full Prescribing Information for JULUCA for more information on potentially significant drug interactions, including clinical comments.
USE IN SPECIFIC POPULATIONS
o Pregnancy: There are insufficient prospective pregnancy data to adequately assess the risk of birth defects and miscarriage. An Antiretroviral Pregnancy Registry has been established.
o Lactation: Breastfeeding is not recommended due to the potential for HIV-1 transmission and the potential for adverse reactions in nursing infants.
DOSAGE AND ADMINISTRATION
o Dosage: 1 tablet taken orally once daily with a meal for adult patients.
o Recommended Dosage of JULUCA with Rifabutin Coadministration: Take an additional 25-mg tablet of rilpivirine with JULUCA once daily with a meal for the duration of the rifabutin coadministration.
