Proteus Maximizes First-Mover Advantage for Digital Therapies

Proteus is a digital health company that is revolutionizing the life sciences industry with groundbreaking solutions that manage and monitor medical care to improve patient outcomes.

The company’s flagship product, Proteus Discover, combines an ingestible sensor, a small wearable sensor patch, a mobile application, and a provider portal. All connected, these elements unlock previously unattainable treatment insights for better clinical outcomes.

Proteus was looking to accelerate its development lifecycle to speed FDA approval and maximize its first-to-market advantage. They had mastered the frontend clinical and diagnostic aspects of the solution but needed help on the backend software development and connectivity and interaction between the different solution elements.

accelerate development lifecycle

Infostretch worked with Proteus (beginning in 2013) across the end-to-end lifecycle – from application development and software verification and validation to system integration and device expansion. Infostretch not only designed a test lab in-house with Patch Test Apparatus (PTA), amplifier and shaker humanoid setup as well as a stimulation setup for patch and firmware testing.

The challenge
A complex vision

Proteus’ product vision was incredibly compelling but executing on that vision was also complex. The company’s core competence was on the frontend – with breakthrough integrations of technology with medicine and in-patient care. However, they had several critical needs on the backend:

  • Management of regulatory compliance requirements within software product development

  • Short lead times for product launches in multiple geographies

  • Time-to-market challenges that prevented proper discipline across the product lifecycle

  • Bluetooth (BLE) connectivity across multiple devices

The Solution
Working as a team

Infostretch worked with the company across the entire delivery lifecycle:

Application Development

Application Development

  • Infostretch enabled the mobile application to communicate continuously via BLE with the patch worn by the patient. Infostretch also supported the company on several other development projects including the middleware for the core company application (both Android and iOS), as well as the web frontend portal for the standard patient application.
  • The development team added new UI features, enhanced communication mechanisms, and fixed defects.
  • It also added new features and improved existing features in the Patient & Provider App in a 2-week development sprint.
  • The team worked on the Integration with Google Analytics & Swrve SDK to capture analytics data and with New Relic to capture Application Crush details.

Software Verification & Validation

Software Verification & Validation

  • Infostretch created an end-to-end process to test and QA the entire service offering across the end-to-end application lifecycle: This included
    • Manual testing of the mobile app
    • Automated testing and QA of the connection of the frontend, backend and middleware
    • Real-life scenarios for testing the mobile app (Patch testing apparatus), physical motion (Step, Incline), medication intake, heartbeat, etc. in addition to generating FDA compliant protocols and documents

    Infostretch also configured & broke BLE signals using Hoffman Box for the interruption testing and the app performance on devices – CPU, Memory usage as a part of Performance Testing.

Systems Integration & Device Expansion

Systems Integration & Device Expansion

  • Infostretch set-up a test center to replicate how the systems would operate and communicate with each other in real life.
  • This included end to end integration tests involving Patch, Cloud, App & Backend.
  • Infostretch automated test scripting and maintenance during sprint-cycle. The team was able to automate 600 test cases per platform daily for regression tests

Infostretch also delivered several other critical capabilities for Proteus:
