研究概览
简要总结
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.
详细描述
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.

主要结局
Medroxyprogesterone Acetate (MPA) Pharmacokinetic Parameter (PK) Area Under the Concentration-time Curve (AUC0-12weeks)
时间窗: Day 0, Weeks 2, 4, 6, 8, 10 and 12
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.
AUC0-12hour for LPV at Baseline (Day 0) Before DMPA Administration and at Week 4 (Four Weeks After DMPA Administration)
时间窗: Day 0 and Week 4
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.
