New study suggests risk of birth defects in babies born to women who were taking dolutegravir at time of conception

May 18, 2018

Preliminary results from an ongoing observational study in Botswana indicate that infants of HIV-infected women taking dolutegravir (DTG) at the time of conception may be at increased risk of neural tube defects. The same study provides no evidence of an increased risk among infants born to women who initiated DTG treatment during pregnancy. Several organizations have issued statements related to these findings, as listed and linked below.

The safety of IMPAACT study participants is of paramount importance to the network and our collaborating partners. The network leadership, including our NIH partners, and the protocol teams for IMPAACT studies of DTG are actively discussing appropriate actions to be taken in response to the new findings. More information and relevant materials will be shared with the sites conducting these studies as soon as decisions are made. In the meantime, any questions should be directed to the respective protocol chairs.
