Ultra-Long-Acting Tunable Biodegradable and Removable Controlled Release Implants for Drug Delivery

Our lab has pioneered the development of an ultra-long-acting injectable formulation that forms an in-situ forming implant (ISFI) once injected into the subcutaneous environment. This formulation offers the ability to integrate multiple drugs in a single injection, the ability to deliver drugs for several weeks or months, and the ability to be removed if required in order to terminate the treatment. This ISFI formulation can be fine-tuned to deliver drugs at targeted release kinetics. Our lab is investigating this formulation for HIV prevention and treatment, as a multipurpose prevention technology (MPT) and for other indications including contraception.
