   Tivicay® (dolutegravir) receives positive CHMP opinion in Europe for the
                               treatment of HIV

PR Newswire

LONDON, Nov. 22, 2013

LONDON, Nov. 22, 2013 /PRNewswire/ --ViiV Healthcare 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 Tivicay^® (dolutegravir) for use in combination with other
antiretroviral medicinal products for the treatment of HIV-infected adults and
adolescents above 12 years of age.

"We welcome the CHMP's positive opinion on dolutegravir – it puts us a step
closer to offering this new treatment option to people across Europe who are
living with HIV," said Dr John Pottage, Chief Medical Officer, ViiV
Healthcare. "We are committed to research that seeks to make advances in
treatment options for people living with HIV. To make progress, thousands of
patients have supported us through their participation in clinical development
work and we recognise their commitment today with great gratitude."

The CHMP opinion is based on safety and efficacy data for dolutegravir from
four pivotal Phase III studies^1-4. These involved people living with HIV who
were new to treatment and also those with prior experience of treatment, and
included comparators representing antiretroviral treatments commonly used
today in the battle against HIV. More than 2,500 people were treated across
these studies, and the regulatory submission also included data in children
aged 12 years and older.

A CHMP positive opinion is one of the final steps in the regulatory process
leading to the marketing authorisation decision of the European Commission,
which is expected early in 2014.

About Tivicay^® (dolutegravir)
Tivicay^® was approved by the U.S. FDA in August 2013 and by Health Canada in
October 2013 – please refer to local labelling for more information. It is a
human immunodeficiency virus type 1 (HIV-1) integrase inhibitor. Integrase
inhibitors block HIV replication by preventing the viral DNA from integrating
into the genetic material of human immune cells (T-cells). This step is
essential in the HIV replication cycle and is also responsible for
establishing chronic infection.

Regulatory applications are being evaluated in other countries worldwide.
Regulatory applications for ViiV Healthcare's developmental single-tablet
regimen (STR) combining Tivicay with Kivexa®/Epzicom® (abacavir/lamivudine)
were submitted to regulatory authorities in Europe, Canada and the U.S. in
October 2013.

Important Safety Information for Tivicay^® (dolutegravir) 50 mg Tablets:

Dolutegravir is not approved for any indication in the European Union. The
following information is based on the Highlights section of the U.S.
Prescribing Information for Tivicay. Please refer to the full Prescribing
Information for more details.

Indication and Usage: Tivicay is indicated in combination with other
antiretroviral agents for the treatment of HIV-1 infection in adults and
children aged 12 years and older and weighing at least 40 kg.

The following should be considered prior to initiating treatment with
Tivicay: poor virologic response was observed in subjects treated with
Tivicay 50 mg twice daily with an integrase strand transfer inhibitor
(INSTI)-resistance Q148 substitution plus 2 or more additional
INSTI-resistance substitutions, including L74I/M, E138A/D/K/T, G140A/S,
Y143H/R, E157Q, G163E/K/Q/R/S, or G193E/R.

Contraindication: Co-administration of TIVICAY with dofetilide
(anti-arrhythmic) is contraindicated due to the potential for increased
dofetilide plasma concentrations and the risk for serious and/or
life-threatening events.

Hypersensitivity Reactions: Hypersensitivity reactions have been reported and
were characterised by rash, constitutional findings, and sometimes organ
dysfunction, including liver injury. The events were reported in 1% or fewer
subjects receiving TIVICAY in Phase 3 clinical trials. Immediately discontinue
TIVICAY and other suspect agents if signs or symptoms of hypersensitivity
reaction develop, (including but not limited to, severe rash or rash
accompanied by fever, general malaise, fatigue, muscle or joint aches,
blisters or peeling of the skin, oral blisters or lesions, conjunctivitis,
facial edema, hepatitis, eosinophilia, angioedema, difficulty breathing.)
Monitor clinical status, including liver aminotransferases, and initiate
appropriate therapy. Delay in stopping treatment with TIVICAY or other suspect
agents after the onset of hypersensitivity may result in a life-threatening
reaction. TIVICAY should not be used in patients who have experienced a
hypersensitivity reaction to TIVICAY.

Effects on Serum Liver Biochemistries in Patients with Hepatitis B or C
Coinfection: Patients with underlying hepatitis B or C may be at increased
risk for worsening or development of transaminase elevations with use of
TIVICAY. 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. Appropriate laboratory
testing prior to initiating therapy and monitoring for hepatotoxicity during
therapy with TIVICAY are recommended in patients with underlying hepatic
disease such as hepatitis B or C.

Fat Redistribution: Redistribution/accumulation of body fat has been observed
in patients receiving antiretroviral therapy.

Immune Reconstitution Syndrome: During the initial phase of treatment, immune
reconstitution syndrome can occur, which may necessitate further evaluation
and treatment. Autoimmune disorders have been reported to occur in the setting
of immune reconstitution; the time to onset is more variable and can occur
many months after initiation of treatment.

Adverse Reactions: The most commonly reported (≥2%) adverse reactions of
moderate to severe intensity in treatment naïve adult subjects in any one
trial receiving TIVICAY in a combination regimen were insomnia (3%) and
headache (2%).

Drug Interactions: Co-administration of TIVICAY with drugs that are strong
inducers of UGT1A1 and/or CYP3A4 may result in reduced plasma concentrations
of dolutegravir and require dose adjustments of TIVICAY.

- TIVICAY should be taken 2 hours before or 6 hours after taking
cation-containing antacids or laxatives, sucralfate, oral iron supplements,
oral calcium supplements, or buffered medications.

- Consult the full Prescribing Information for TIVICAY for more information on
potentially significant drug interactions, including clinical comments.

Pregnancy: Pregnancy category B. TIVICAY should be used during pregnancy only
if the potential benefit justifies the potential risk. An Antiretroviral
Pregnancy Registry has been established.

Breastfeeding: Breastfeeding is NOT recommended due to the potential for HIV
transmission and the potential for adverse reactions in nursing infants.

Paediatric Patients: Safety and efficacy of TIVICAY has not been established
in children younger than 12 years old, or weighing <40 kg, or in
INSTI-experienced paediatric patients with documented or clinically suspected
INSTI resistance.
