Despite the benefits of hormonal contraceptives, significant drug-drug interactions (DDIs) with some antiretroviral therapies (ART) represent a barrier to effective family planning methods for HIV-infected women. It is therefore critical to generate data on the combined use of hormonal contraceptives and ART. This study is a prospective, non-randomized, open-label, parallel, two-group, sparse-sampling pharmacokinetic study to describe etonogestrel (ENG) pharmacokinetic (PK) parameters in two treatment groups (rilpivirine or darunavir- based ART) in 60 HIV-1 infected women. The primary endpoint is the comparison of the mean ENG concentrations at month 6 between the rilpivirine or darunavir treatment groups versus historical controls. This study will provide information on effective ART options for HIV positive women who opt for the contraceptive implant as a family planning method of choice.
This study will evaluate the pharmacokinetic properties of rilpivirine and darunavir when used in combination with etonogestrel
