Shionogi-ViiV Healthcare Starts Phase III Trial for '572-Trii' Fixed-Dose Combination HIV Therapy

LONDON, Feb. 3, 2011 /PRNewswire/ -- Shionogi-ViiV Healthcare, LLC announced today that the first patient has entered the clinical study, SINGLE (ING114467), designed to support a new fixed-dose combination (FDC) therapy for the treatment of HIV.  The new investigational regimen, known as 572-Trii, will combine the investigational integrase inhibitor S/GSK1349572 ('572) and ViiV Healthcare's combination nucleoside reverse transcriptase inhibitor (NRTI) Kivexa®/Epzicom® (ABC/3TC).

"ViiV Healthcare's goal is to understand and be responsive to the needs of people living with HIV," stated Dominique Limet, Chief Executive Officer, ViiV Healthcare. "With this programme, we are seeking to create an integrase-based, once-daily fixed dose combination that helps meet  patient needs.  We know that even with the successes of current therapies, patients still need additional treatment options and we will continue to evaluate existing and pipeline compounds for new combination therapies."  

"The study of a fixed-dose combination therapy that includes '572 is a signal of Shionogi and ViiV Healthcare's confidence in the compound's potential," said Dr. Sapan Shah, President & CEO, Shionogi Inc. "We're optimistic that '572 will continue to show promise through this research and in the other ongoing Phase III studies that are evaluating it in other HIV treatment regimens."

About the Study: SINGLE (ING114467)

The SINGLE study (ING114467) is a multi-centre, multinational, double-blind, two arm study designed to compare the efficacy and safety of 572-Trii ('572 plus ABC/3TC) with that of efavirenz/tenofovir/emtricitabine (EFV/TDF/FTC). This study will include approximately 800 HIV-1 infected treatment-naive patients.

The primary objective for the SINGLE study will be to demonstrate the antiviral activity of 572-Trii once-daily therapy compared to EFV/TDF/FTC over 48 weeks. Secondary objectives include the assessment of the tolerability, long-term safety, and antiviral and immunologic activity of 572-Trii once-daily compared to EFV/TDF/FTC over 96 weeks.  Investigators will also evaluate viral resistance in patients experiencing virologic failure.

Together with the planned FDC bioequivalence study (ING114580) comparing the 572-Trii FDC tablet with '572 plus ABC/3TC, the SINGLE study is designed to support a regulatory filing for 572-Trii as a new fixed dose combination of '572/ABC/3TC.


KIVEXA/EPZICOM (abacavir/lamivudine) is a once-a-day HIV medication that combines abacavir sulfate and lamivudine in a single tablet and is indicated for the treatment of HIV-1 infection in adults.

Important Information about EPZICOM

EPZICOM, in combination with other antiretroviral agents, is indicated for the treatment of HIV-1 infection in adults.

EPZICOM is one of 3 medicines containing abacavir. Before starting EPZICOM, your healthcare professional will review your medical history in order to avoid the use of abacavir if you have experienced an allergic reaction to abacavir in the past.

In one study, more patients had a severe hypersensitivity reaction in the abacavir once-daily group than in the abacavir twice-daily group.

EPZICOM should not be used as part of a triple-nucleoside regimen.

EPZICOM does not cure HIV infection/AIDS or prevent passing HIV to others.

Important Safety Information

EPZICOM contains abacavir, which is also contained in ZIAGEN® (abacavir sulfate) and TRIZIVIR® (abacavir sulfate, lamivudine, and zidovudine). Patients taking EPZICOM may have a serious allergic reaction (hypersensitivity reaction) that can cause death. The risk of this allergic reaction is much higher if one has a gene variation called HLA-B*5701 than if one does not. Your doctor can determine with a blood test if you have this gene variation. If you get a symptom from 2 or more of the following groups while taking EPZICOM, call your doctor right away to determine if you should stop taking this medicine:

  1. Fever
  2. Rash
  3. Nausea, vomiting, diarrhea, or abdominal (stomach area) pain
  4. Generally ill feeling, extreme tiredness, or achiness
  5. Shortness of breath, cough, or sore throat

Carefully read the Warning Card that your pharmacist gives you and carry it with you at all times.

If you stop EPZICOM because of an allergic reaction, NEVER take EPZICOM or any other abacavir-containing medicine (ZIAGEN, TRIZIVIR) again. If you take EPZICOM or any other abacavir-containing medicine again after you have had an allergic reaction, WITHIN HOURS you may get life-threatening symptoms that may include very low blood pressure or death.

If you stop EPZICOM for any other reason, even for a few days, and you are not allergic to EPZICOM, talk with your healthcare professional before taking it again. Taking EPZICOM again can cause a serious or life-threatening reaction, even if you never had an allergic reaction before. If your healthcare professional tells you that you can take EPZICOM again, start taking it when you are around medical help or people who can call a doctor if you need one.

A build-up of lactic acid in the blood and an enlarged liver, including fatal cases, has been reported.

Do not take EPZICOM if your liver does not function normally.

Some patients infected with both hepatitis B virus (HBV) and HIV have worsening of hepatitis after stopping lamivudine (a component of EPZICOM). Discuss any change in treatment with your doctor. If you have both HBV and HIV and stop treatment with EPZICOM, you should be closely monitored by your doctor for at least several months.

Worsening of liver disease (sometimes resulting in death) has occurred in patients infected with both HIV and hepatitis C virus who are taking anti-HIV medicines and are also being treated for hepatitis C with interferon with or without ribavirin. If you are taking EPZICOM as well as interferon with or without ribavirin and you experience side effects, be sure to tell your doctor.

When you start taking HIV medicines, your immune system may get stronger and could begin to fight infections that have been hidden in your body, such as pneumonia, herpes virus, or tuberculosis. If you have new symptoms after starting your HIV medicines, be sure to tell your doctor.

Changes in body fat may occur in some patients taking antiretroviral therapy. These changes may include an increased amount of fat in the upper back and neck ("buffalo hump"), breast, and around the trunk. Loss of fat from the legs, arms, and face may also occur. The cause and long-term health effects of these conditions are not known at this time.

Some HIV medicines, including those containing abacavir (ZIAGEN, EPZICOM or TRIZIVIR), may increase one's risk of heart attack. If one has heart problems, smoke, or suffers from diseases that increase the risk of heart disease such as high blood pressure, high cholesterol, or diabetes, they should tell their doctor.

The most common side effects seen with the drugs in EPZICOM dosed once-daily were allergic reaction, trouble sleeping, depression, headache, tiredness, dizziness, nausea, diarrhea, rash, fever, stomach pain, abnormal dreams, and anxiety. Most of the side effects do not cause people to stop taking EPZICOM.
