Overview

TZIELD® is the first treatment proven to delay Stage 3 Type 1 Diabetes in patients 8 years and older with Stage 2 T1D. To raise awareness, the brand needed to engage PCPs, Pediatricians, and Endocrinologists-many encountering TZIELD for the first time—while identifying which placements and messages drove engagement. Using a fixed NPI match list, Wrango’s physician-level reporting and HCP Journeys analytics uncovered which HCPs were most receptive, what messaging resonated, and how optimizations could improve results in real time.

Business Challenge

TZIELD needed to increase awareness among PCPs, Pediatricians, and Endocrinologists through a highly targeted video campaign. With a predefined match list, the challenge was not just driving engagement within a fixed audience but also understanding how HCPs interacted with the brand beyond ad exposure. To optimize performance and refine future marketing efforts, the brand required a data-driven solution that could measure engagement, track behavioral patterns, and identify signals of deeper interest.

Our Solution

Wrango launched a precision-targeted video campaign, leveraging the client’s NPI match list to ensure messaging reached the right HCPs efficiently.

Beyond activation, HCP Journeys analytics provided real-time visibility into how prescribers engaged with both the ads and TZIELD’s website, uncovering key behavioral insights.

By analyzing content interactions, site navigation patterns, and specialty-level engagement, Wrango identified which messages resonated most, which HCPs showed the highest interest, and how digital touchpoints influenced intent. These insights enabled continuous campaign optimizations, driving stronger engagement while equipping TZIELD with actionable data to refine its future HCP marketing strategy.
