Seronegatives and Metabolic Abnormalities Protocol 2 (SAMA002): Study to Compare the Effect of Kaletra and Combivir® in HIV-Negative Healthy Subjects
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.

This is a randomised study of the effect of treatment with Combivir (zidovudine [AZT] and lamivudine [3TC]) and Kaletra (lopinavir [LPVr]), alone and in combination, on the development of abnormalities in lipid and glucose metabolism in HIV negative healthy subjects.
Condition or disease
HIV InfectionsDyslipidemiasGlucose Metabolism DisordersMetabolic DiseasesLipodystrophyCardiovascular Disease
Antiretroviral medications, used to treat HIV infection, cause side effects. These include changes in the way that fat is laid down on the body. This results in fat loss from some parts of the body, with fat deposits at other sites, giving a characteristic look known as "HIV associated lipodystrophy" or HIVLD. With these changes, there are also abnormalities in glucose and fat metabolism (collectively termed metabolic abnormalities). In HIV negative populations, these metabolic changes are associated with an increased risk of developing cardiovascular disease (CVD). The aim of this study is to investigate if changes in the body's handling of fats and glucose occur with a short course of treatment in HIV negative subjects and if these correlate to an increased risk of CVD.
A 3 Arm, Prospective Study to Compare the Effect of 6 Weeks Exposure to the Combination of Lopinavir (LPVr)/Combivir® (AZT/3TC) Versus Lopinavir Alone or Combivir® Alone in HIV-negative Healthy Subjects on the Development of Abnormalities of Lipid and Glucose Metabolism

Accepts Healthy Volunteers:
Be able to provide written consent to perform in the trial.
HIV antibody negative and HIV DNA negative at time of entry to the study.
Any history of, or ongoing, mental or physical condition (including suspected or known diagnosis of ischaemic heart disease), which, in the opinion of the investigator, would impede the subject's ability to participate in the trial.
History of type I or type II diabetes mellitus or previous treatment with antidiabetic medication.

Any grade-three laboratory abnormality recorded from screening bloods.
Any grade-two laboratory abnormality recorded from screening bloods, which, in the opinion of the investigator, would impede the subject's ability to safely complete all study requirements.
Gastrointestinal disorders, which may affect drug absorption.
Any finding on screening clinical examination, which, in the opinion of the investigator, would impede the subject's ability to participate in the rest of the trial.
Evidence of acute or chronic active hepatitis B virus infection by serology performed at baseline.
Evidence of hepatitis C infection by serology performed at baseline.
