Brief summary: The purpose of this study is to investigate the efficacy, safety, and tolerability of an investigational treatment for patients with Human Immunodeficiency Virus (HIV).


Eligibility criteria: Inclusion Criteria:

* Patient is at least 18 years of age
* Patient is human immunodeficiency virus (HIV) positive
* Patient has documented Human Immunodeficiency Virus (HIV) RiboNucleic Acid (RNA) \<50 copies/milliliter (mL) for at least 3 months while on a KALETRA based regimen
* Patient has been on a KALETRA based regimen for at least 3 months without a change in background antiretroviral therapy
* Patient has no documentation of HIV RNA \>50 copies/mL for at least 3 months while on the KALETRA based regimen

Exclusion Criteria:

* Patient is or plans to become pregnant, or is nursing a child
* Patient plans to donate eggs or impregnate/donate sperm
* Patient is receiving Stavudine (d4T) as a component of the background antiretroviral therapy
* Patient is currently receiving a second protease inhibitor in addition to KALETRA
* Patient is currently receiving, or has received in the past twelve weeks, treatment for the management of elevated lipids
* Patient has used another experimental HIV-integrase inhibitor
* Patient has a current (active) diagnosis of acute hepatitis due to any cause
