Expected Enrollment: 40 patients Study Start Date: June 2005 Study Objectives: - To conduct a pilot study to assess the safety, tolerability, and antiviral activity of Kaletra 400/100 mg taken twice a day (bid) in antiretroviral (ARV)-naïve HIV-infected patients at Week 48 Primary Objectives: - To determine the proportion of patients with HIV RNA <400 copies/mL at weeks 24 and 48 - To determine the proportion of patients with HIV RNA < 50 at weeks 24 and 48 - To elucidate the specific adverse event (AE) profile of Kaletra single agent therapy Secondary Objectives: - To assess the proportion of patients below the limit of quantification (LOQ) at each visit. Patients will be observed at baseline, weeks 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44 and 48. - To determine the time to HIV RNA reaching <400 and <50 copies/mL - To determine the time to virologic failure - To assess change from baseline at each visit for HIV RNA and CD4 count at weeks 4, 8, 12, 24 and 48. - To assess changes in genotype from baseline to time of confirmed virologic failure (2 consecutive HIV RNA measurements >400 copies/mL after suppressing to <400 copies/mL) or at time of treatment intensification. - To characterize changes in lipid and triglyceride concentrations over time and the effect of treatment with appropriate drugs (fibrate or statin, if necessary) on these elevations. - To evaluate the safety and tolerability of subjects through 48 weeks of drug exposure. - To describe virologic response following intensification in Kaletra single agent virologic failures

- Patient has an M184V mutation in reverse transcriptase, or mutations at 10, 20, 32, 46, 47, 48, 50, 54, 71, 73, 82, 84, or 90; - K65R mutation or 2 or more TAMs at baseline - History of active substance abuse, excluding cannabis, or psychiatric illness that, in the opinion of the investigator, would preclude compliance with protocol, dosing schedule and assessments. --- M184V --- --- K65R ---
