Proteus Digital Health Accelerates Time to Market
CASE STUDY
Proteus Digital Health• Integrating the intake of medicine with ingestible sensors,
wearable devices, mobile and data analytics.• Providing an unprecedented view into personal health
choices and physiologic response, allowing patients to better manage their health and collaborate with caregivers and clinicians.
• Received CE mark in Europe and FDA clearance in the U.S postmarket. Clinical trials are underway.
Responding to three macro trends in health today:1. There are more people with mobile phones than with access
to clean, running water today.2. Chronic diseases like diabetes, often lifestyle-related, are
the world’s biggest healthcare problem and existing health systems can’t cope.
3. The increased use of wearable devices and sensors to manage health.
Challenges:• Regulatory compliance
required to bring new healthcare products to market
• Cost and time to market impact at every phase of the product lifecycle
• Geo and country-specific requirements
• BLE connectivity across multiple devices
Solution:• Development effort to
enable secure, continuous communication via BLE between Proteus Patch and mobile device and backend systems
• Combination of manual and automated testing across multiple sensors, layers, mobile and wearable devices
• Selenium for web automation
Results:• Addressed several difficult
development challenges to enhance product quality and accelerate time to market
• Automated over 65% of testing requirements
• Reduced app testing time by 40%

OVERVIEWProteus is pioneering a new category of products, services and data systems based on integrating the intake of medicine with ingestible sensors, wearable devices and data analytics. The Proteus service offering, integrates medicines that treat chronic conditions with mobile technologies to make healthcare more accessible, manageable and affordable.
CHALLENGESThe Proteus service offering includes a unique combination of technologies and concepts – therapeutic dosage/delivery and patient compliance monitoring on one end; mobile sensors, wearable devices, networks and data analytics on the other.
The company’s core competence was on the front end with medicine delivery and patient care. It needed a technology partner equally qualified to support it on the backend – with expertise in mobile technologies, wearables and the fast-growing area known as the “Internet of Things.” A partner that:
• understood the requirements of a startup company and could respond to its need for speed and flexibility.
• had the expertise to guide its development and test/QA efforts on the mobile technology side of its solution across multiple geographies, markets and platforms.
Proteus was looking to accelerate its development cycle while ensuring an accurate, high quality user experience regardless of the mobile device or operating system.
SOLUTIONToday, InfoStretch’s engagement at Proteus touches almost every aspect of how the offering works. DevelopmentInfoStretch started working with Proteus to enable its mobile application to communicate continuously via BLE with the Proteus Patch worn by the patient. The communication is very secure and uses Proteus’ proprietary protocol to transmit data to the mobile application. The mobile app then crunches the data using complex algorithms and generates important metrics such as medicine taken, number of steps, body angle and vital signs. After it processes these inputs, the application uploads the data to a backend server for further analytical analysis. Precision is key given the medical nature of the data.
InfoStretch also supported Proteus on several other development projects including the middleware for the core Proteus application – supporting both Android and iOS – as well as the Web front end portal for the standard patient application. This involved:
• Setting up an onshore-offshore hybrid team that quickly came up to speed on Proteus’ mobile architecture.
• Working closely with the Proteus engineering team in agile mode to build enhancements, features and solve complex BLE-related connectivity challenges.
• Incorporating defined processes and systems to ensure quality and re-use.• Meeting regulatory standards required with medical data.
Proteus Digital Health Accelerates Time to MarketProteus’ vision is to integrate medicines that treat chronic conditions with mobile technology – via its ingestible sensors and wearable patches – to make healthcare more accessible, manageable and innovative.
InfoStretch handled the project with a balanced on shore/off shore model accelerating cycle time and reducing costs for Proteus.

Software Verification and ValidationInfoStretch created an end to end process to test and QA the entire service offering across the entire application lifecycle. This included:
• Manual testing of the Proteus mobile app running on the patient’s cell phone across multiple devices and operating systems.
• Automated testing and QA of the connection of the front end, back end and middleware for Proteus’ PHAROS, the proprietary app that connects the mobile app to medical applications in the hospital as well as health records portal.
• QA testing of the system’s firmware – the semiconductor and communication between the ingestible sensors, the wearable patches applied to patients to communicate with the sensor, the mobile app on the cell phone and Proteus’ backend systems.
• Simulation of real-life patient reactions to the ingestible, wearable patch and related external factors.
Both projects required a very structured approach to application testing and script development. InfoStretch also set up a dedicated testing lab to meet stringent FDA protocol requirements.
Performance and Scalability TestingThe engagement also included performance testing on the backend – checking capacity performance and scalability of the Proteus backend platform.
Systems Integration & Device Expansion One of the essential elements of the Proteus offering was its ability to have all the different pieces working together as one. InfoStretch was engaged here to simulate this including setting up a test center to replicate how the systems would operate and communicate in real life. InfoStretch also worked with Proteus to ensure the offering would work from one device, carrier and operating system to the next. This involved simultaneous testing on various mobile and wearable devices and providing recommendations to the Proteus development team for execution.
Site Reliability MonitoringInfoStretch was also engaged to monitor the Proteus servers in its Redwood City data center which hosts the Proteus application. InfoStretch provides remote system monitoring, regular performance reports, automatic alarms, alerts and real-time capacity sizing.
RESULTSThe InfoStretch team has been able to respond to every challenge and guide Proteus’ development and testing efforts to help enhance product quality and accelerate time to market. Specific highlights include:
• Solved several difficult BLE connectivity challenges integral to the operation of the Digital Health Feedback System.
• Automated over 65% of testing requirements using Selenium Framework.• Reduced app testing time by 40%.• Enabling simultaneous testing on various mobile and wearable devices. • Extending existing Proteus frameworks and tools to include more advanced
functionalities.
