A Novel Capsule-Delivered Enteric Drug-Injection Device for Delivery of Systemic Biologics: A Pilot Study in a Porcine Model
Here, we report a swallowable capsule for intestinal drug delivery (SCIDD) with the potential of directly injecting biological therapeutics into the small intestine wall. The design, optimization, and validation of the SCIDD's primary subsystems were performed both ex-vivo and in-vivo. The assembled capsule was further tested in vivo to validate the actuation sequence which showed a 70% success rate in an animal model. A drug delivery study indicated systemic uptake of adalimumab via SCIDD compared with luminal delivery in the small intestine. The pilot study presented here establishes that the novel platform could be used to orally deliver systemic biologics... Read more
