The first study of its kind involving the dapivirine vaginal ring in breastfeeding women, MTN-029/IPM 039 found very low concentrations of dapivirine released from the ring into the vagina were absorbed by breastmilk in lactating women. Sixteen women who were no longer breastfeeding but were still producing breast milk were enrolled into the study and used the ring for 14 consecutive days. Results, which were reported at IAS 2017, supported additional studies of the dapivirine ring in breastfeeding women. (See MTN-043/B-PROTECTED.)
