This study was designed to test the safety and effectiveness of EPZICOM(abacavir/lamivudine) and TRUVADA (emtricitabine/tenofovir) for the treatment of HIV infection when both are used in combination with KALETRA (lopinavir/ritonavir) over 96 weeks
Phase 4

Emtricitabine, Tenofovir Disoproxil Fumarate Drug Combination
Inclusion criteria:

- Males as females at least 18 years old. (A female is eligible to enter and participate
in this study if she is of: non child-bearing potential, child bearing potential with
a negative pregnancy test and agrees to approved contraception methods, or agreement
for complete abstinence.)

- Subject is antiretroviral-naïve (defined as having ≤14 days of prior therapy with any
NRTI and no prior therapy with either a PI or NNRTI).

- Subject has plasma HIV-1 RNA ≥ 1,000 copies/mL at screening.

- Subject is willing and able to understand and provide written informed consent prior
to participation in this study.

Exclusion criteria:

- Subject has an active or acute CDC Clinical Category C event (exclusive of cutaneous
Kaposi's sarcoma) at screening. Treatment for the acute event must have been completed
at least 30 days prior to screening.

- Subject is enrolled in one or more investigational drug protocols, which may impact
HIV-1 RNA suppression.

- Subject is, in the opinion of the investigator, unable to complete the 96-week dosing
period and protocol evaluations and assessments.

- Subject is either pregnant or breastfeeding.

- Subject has an ongoing clinically relevant pancreatitis or clinically relevant
hepatitis at screening.

with drug absorption or render the subject unable to take oral medication.

- Subject has any acute laboratory abnormality at screening, which, in the opinion of
the investigator, precludes the subject's participation in the study of an
investigational compound. Any grade 4 laboratory abnormality will exclude a subject
from study participation.

- Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) >5 times the upper
limit of normal (ULN).

- Subject has required treatment with radiation therapy or cytotoxic chemotherapeutic
agents within 28 days prior to screening, or has an anticipated need for these agents
within the study period.

- Subject requires treatment with immunomodulating agents (such as systemic
corticosteroids, interleukins, vaccines, or interferons) within 28 days prior to
Screen, or subject has received an HIV-1 immunotherapeutic vaccine within 90 days

activity against HIV-1 in vitro within 28 days of study administration.

- Subjects who require treatment with the prohibited medications within 28 days of
commencement of investigational product, or an anticipated need during the study.
