Proteus Digital Health Inc. hopes its Helius computer-enabled ingestible sensor system can deliver real-time monitoring of oral medication outcomes. The company's challenges are to convince payers that the added cost of the system is justified in therapeutic areas that are dominated by cheap generics and to overcome patient concerns over privacy and ease of use.

The company is working to overcome those challenges through data collection and experience with a marketed version of the product that uses a standalone sensor co-administered with a patient's medication.
