History

2026: UNC Chapel Hill, NC State, and CONRAD at Old Dominion University publish results of formulation/drug loading, drug release, and physiochemical interaction evaluation for a 3D-printed IVR loaded with two non-hormonal contraceptive agents, lactic acid and glycerol monolaurate. Results suggest that co-delivery of the two APIs for 30+ days is viable and the device is likely to be biocompatible and stable. They indicate their intention to proceed to a sheep model for in vivo testing.
