Driving Engagement in Large-Scale Vaccine Trial

This case study showcases how Signant collaborated with clinical trial payments solution provider Greenphire to support a major pharmaceutical company's vaccine trial involving 44,000+ participants across 150+ global sites.

The integration enabled daily data exchange between Signant's eCOA platform and Greenphire's payment system, delivering 30,000 weekly micropayments to participants.

Despite an accelerated five-week timeline, Signant successfully deployed their solution worldwide, including 8,000+ provisioned devices.

This partnership:

• Improved participant retention through strategic micropayments
• Reduced site workload
• Maintained high-quality data collection for up to two years post-vaccination

The eCOA data contributed to regulatory submissions that secured FDA authorization for the vaccine.
