Update to Sections 4.2, 4.4, 4.6 of the SmPC for Tybost to recommend to not initiate darunavir/cobicistat (DRV/co) during pregnancy, and to switch to an alternative regimen (DRV/ritonavir may be considered as an alternative) for women who become pregnant during therapy with DRV/co in alignment with the SmPCs for Prezista and Rezolsta (Janssen products). The Janssen SmPCs were updated based on data from study TMC114HIV3015. This study has showed that treatment with DRV/co in pregnant women resulted in lower darunavir and cobicistat exposures during the second and third trimesters of pregnancy compared to postpartum.
Section 4.6 of the SmPC for Tybost was also updated in respect to atanazavir/cobisistat use during pregnancy to align with the SmPC for Evotaz (BMS product).
The Package Information Leaflet (PIL) for all three products was updated accordingly.
With this procedure, Gilead has been requested to issue a Dear Healthcare Professional Communication (DHPC) to inform about the increased risk of treatment failure and increased risk of mother-to-child transmission of HIV infection due to lower exposure of elvitegravir and cobicistat during the second and third trimesters of pregnancy. The DHPC was disseminated as per the agreed communication plan.
