  Purpose
This study was done to look at the level of Depo-Provera, an injectable birth control, in the blood to see whether it is affected by the anti-HIV drug Kaletra (lopinavir/ritonavir [LPV/r]). It is not known whether taking Depo-Provera together with Kaletra changes the amount of Kaletra in blood. Therefore, this study also looked at the levels of HIV and Kaletra before and after receiving a shot of Depo-Provera. This study evaluated the safety of Depo-Provera and Kaletra when they are used together. In addition to what is stated above, this study also explored any effect of Depo-Provera on the immune system.

    This evaluates the effect of lopinavir/ritonavir (LPV/r) on pharmacokinetic parameter AUC of MPA by looking at the MPA AUC from day 0 to week 12. AUC0-12weeks was calculated using single MPA concentrations sampled immediately prior to DMPA administration on day 0, and at 2, 4, 6, 8, 10 and 12 weeks after administration of the single DMPA dose.

    This evaluates the effect of DMPA on LPV PK parameter AUC by comparing PK AUCs of LPV from 0 to 12 hours obtained at study Day 0 (before DMPA was administered) with PK AUCs of LPV from 0 to 12 hours at study Week 4 (4 weeks after DMPA was administered). Blood samples were drawn for LPV concentration levels at time zero (before LPV/r dosing) and at 30 minutes and 1, 2, 3, 4, 5, 6, 8 and 10 hours after LPV/r dosing at day 0 and week 4.

    This evaluates toxicity and safety of concomitant medication of DMPA and LPV/r, focusing specifically on the adverse event (AE) menstrual irregularities with abnormal vaginal bleeding. The AEs were graded by the clinicians according to the Division of AIDS (DAIDS) AE Grading Table (see references in the Protocol Section) as follows: Grade 1=Mild, Grade 2=Moderate, Grade 3=Severe, Grade 4=Potentially Life-Threatening, Grade 5=Death.

An FDA-approved HIV-1 RNA assay with a lower limit of detection of 75 copies/mL or less was required and the same HIV-1 RNA assay was required to be performed for each participant across all study visits. The Roche COBAS AmpliPrep/TaqMan HIV-1 and Abbott RealTime HIV-1 tests were used.

Summary of adjusted ELISPOT assay results is in spot forming cells (SFC)/10^6 peripheral blood mononuclear cells (PBMC) by study weeks 0, 4 and 12. The outcome measures of IFN-gamma and IL-2 measured for HIV and VZV are presented here together to provide all results pertaining to the same objective in a single data table.

The data table shows a summary of LPA assay results by study week with stimuli HIV and VZV. Proliferation results are reported as a stimulation index (SI) which represents the ratio of the stimulated counts per minute to unstimulated control counts per minute.

Detailed Description:

The primary study objective was addressed by calculating the Area Under the Concentration-Time Curve (AUC) from week 0 (prior to DMPA injection) to week 12 (twelve weeks after DMPA injection) in our study participants.

DMPA was supplied and administered as part of the protocol, however Kaletra was not. It was required that participants already be on a Kaletra based regimen prior to entering the study, as described in the eligibility criteria.

Arm A of AIDS Clinical Trial Group (ACTG) A5093, which consisted of 14 participants who were administered DMPA without Kaletra, was used as reference data.
