Study Summary

This study was done to look at a method of hormonal birth control, called the NuvaRing, and specific anti-HIV medications, called antiretrovirals (ARVs). Some studies of women who use a hormonal birth control method (specifically oral pills, patches, and injections) and take ARVs have shown that ARVs interact with the hormones released by the birth control medication. These interactions may cause the birth control to be less effective at preventing pregnancy. There is also concern that hormonal birth control can increase HIV spreading to others, but more studies are needed to determine if this is true. The investigators did not know whether the NuvaRing and ARVs interact when they are used together, so this study looked to see if certain ARVs (efavirenz and atazanavir/ritonavir) interact with the two hormones released by NuvaRing. This will help us to determine if NuvaRing is safe and effective for women with HIV infection who are taking ARVs. The study also included HIV-infected women who were not on ARVs but used the NuvaRing to show us what the hormone levels are like in a similar group of women not on ARVs. Vaginal rings are also currently being studied to deliver anti-HIV medications that may prevent HIV acquisition, and to provide birth control over a longer period of time (more than 1 month). Since vaginal rings will become more commonly used to administer medications, the investigators wanted to better understand the potential for drug interactions with drugs given vaginally. This study will also help us understand the potential for drug interactions between ARVs given orally, and other drugs given through vaginal rings, like the NuvaRing. Additionally, this study will help us understand how hormones released from a vaginal ring affect the amount of HIV virus in the genital tract, the bacterial make-up (microbiome) of the female genital tract, and the immune system within the genital tract, all of which may affect the chances of spreading HIV.

Primary Outcome

This evaluates the effect of EFV and ATV/r on etonogestrel by measuring etonogestrel concentrations on all three study arms 21 days after NuvaRing administration. The pharmacokinetic (PK) blood sample for measurement of etonogestrel on study day 21 was taken before the NuvaRing was removed. The assay lower limit of quantification for etonogestrel was 250 pg/mL; values \< 250 were assigned a value of half the lower limit (ie, 125 pg/mL).
