Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Geometric mean and geometric mean ratios (90% confidence interval) of piperaquine pharmacokinetic parameters when DP-IPTp is co administered with 50 mg dolutegravir based ART compared to 600 mg efavirenz-based ART | — |
Secondary
| Measure | Time frame |
|---|---|
| Geometric Mean Ratios (90% confidence interval) of maternal piperaquine concentrations in women living with HIV on 50 mg dolutegravir based ART compared to women not living with HIV (so not on ART) and not on azithromycin, matched for time since last DP dose and body weight and umbilical cord piperaquine concentration ratios in women living with HIV on 50 mg dolutegravir-based ART compared to women not living with HIV (so not on ART);Geometric mean and geometric mean ratios (90% confidence interval) of piperaquine pharmacokinetic parameters of exposure when dolutegravir-based ART is administered alone compared with co-administration with DP-IPTp;Mean maternal and umbilical cord plasma dolutegravir concentrations in women living with HIV on 50 mg dolutegravir-based ART | — |
