Key Takeaways

A massive three-year, four-protocol pivotal study requiring over 6,700 global participants demanded the highest level of strategic planning, coordination and precise execution to achieve on-time enrollment.

BBK developed a robust, centralized advertising campaign that drove patients to sites in record numbers — boosting screening rates by over 50% and resulting in over 25,000 referrals in 30 months.

Solution and Impact

The three-year enrollment window allowed BBK to consistently optimize tactical outreach to meet the changing recruitment landscape — as it pertained both to available treatments and to the technological evolution and adoption of mobile devices. BBK anticipated and capitalized on the mobile revolution before competitors could react, maximizing outreach platforms that resulted in a 377% spike in website traffic over a 12-month period and yielded 14,879 new referrals.
