Labeling Changes to 3 HIV Drugs
FDA has approved labeling revisions for three HIV drugs to include information on the risk of neural tube defects. The changes apply to ViiV’s Tivicay (dolutegravir), Triumeq (abacacir, dolutegravir, and lamivudine), and Juluca (dolutegravir, rilpivirine). In addition, weight gain was added to the Postmarketing Experience subsection of each label.
In a Drug Safety Communication on the changes, FDA says serious cases of neural tube birth defects involving the brain, spine, and spinal cord have been reported in babies born to women treated with dolutegravir. It reports that preliminary results from an ongoing observational study in Botswana found that women who received dolutegravir at the time of becoming pregnant or early in the first trimester appear to be at higher risk for the defects.
