Abstract: Components with relatively high loading of active pharmaceutical ingredients (e.g., drugs), are generally provided. In some embodiments, the component (e.g., a tissue interfacing component) comprises a solid therapeutic agent (e.g., a solid API) and a supporting material (e.g., a binder such as a polymer) such that the solid therapeutic agent is present in the component in an amount of greater than or equal to 10 wt % versus the total weight of the tissue interfacing component. Such tissue-interfacing components may be useful for delivery of API doses e.g., to a subject. Advantageously, in some embodiments, the reduction of volume required to deliver the required API dose as compared to a liquid formulation permits the creation of solid needle delivery systems for a wide variety of drugs in a variety of places/tissues (e.g., tongue, GI mucosal tissue, skin) and/or reduces and/or eliminates the application of an external force in order to inject a drug solution through the small opening in the needle. In some cases, a physiologically relevant dose may be present in a single tissue interfacing component (e.g., having a relatively high API loading).

Abstract: A drug delivery device for administration to a subject may include a reservoir containing an active pharmaceutical ingredient and a potential energy source. The drug delivery device may also include a trigger operatively associated with the potential energy source. The trigger may be configured to actuate at a predetermined location within the subject to deploy a jet of the active pharmaceutical ingredient into a tissue of an adjacent portion of the gastrointestinal tract. In some instances, the jet may be deployed into tissue of the stomach and/or small intestine of the subject. Further, in some embodiments, the operating parameters of the jet may be selected such that the jet penetrates the tissue of the gastrointestinal tract to form a depot of the active pharmaceutical ingredient disposed within the tissue.

Abstract: Gastric resident electronics, devices, systems, and related methods are generally provided. Some embodiments comprise administering (e.g., orally) an (electronic) resident structure to a subject (e.g., a patient) such that the (electronic) resident structure is retained at a location internal to the subject for a particular amount of time (e.g., at least about 24 hours) before exiting said location internal to the subject. In some embodiments, the resident structure is a gastric resident electronic. That is to say, in some embodiments, the resident structure is configured for relatively long gastric residence and comprises an electronic component. In some embodiments, the structures and components described herein may comprise one or more components configured for the delivery of an active substance(s) (e.g., a pharmaceutical agent) to the subject. In some embodiments, the device has a modular design, combining an electronic component(s) with materials configured for controlled and/or tunable degradation/dissolution to determine the time at which (gastric) residence is lost and the device exits the location internal to the subject. For example, in some embodiments, the resident structure comprises an electronic component and one or more additional components associated with the electronic component such that the resident structure is configured to be retained at a location internal to a subject for greater than or equal to 24 hours.

Abstract: Transient molecules in the gastrointestinal (GI) tract, such as nitric oxide and hydrogen sulfide, are important signals and mediators of inflammatory bowel disease (IBD). Because these molecules may be short-lived in the body, they are difficult to detect. To track these reactive molecules in the GI tract, a miniaturized device has been developed that integrates genetically engineered probiotic biosensors with a custom-designed photodetector and readout chip. Leveraging the molecular specificity of living sensors, bacteria were genetically encoded to respond to IBD-associated molecules by luminescing. Low-power electronic readout circuits (e.g., using nanowatt power) integrated into the device convert the light from just 1 μL of bacterial culture into a wireless signal. Biosensor monitoring was demonstrated in the GI tract of small and large animal models and integration of all components into a sub-1.4 cm3 ingestible form factor capable of supporting wireless communication. The wireless detection of short-lived, disease-associated molecules may support earlier diagnosis of disease than is currently possible, more accurate tracking of disease progression, and more timely communication between patient and their care team supporting remote personalized care.
