Your Enrollment Problem Isn't a Site-Selection Problem. Here’s Why.

You selected your sites carefully. Six months in, enrollment is behind. The instinct: find better sites, bring more online. But site selection wasn’t the constraint. Narrow eligibility criteria were eliminating patients before a site could enroll them. In a Parkinson's Market Feasibility Test (a patient survey run before a single site opens) only 4% of 214 respondents qualified despite strong awareness. Every person who qualified wanted to participate. One narrow eligibility requirement created the bottleneck, not a site-selection decision. And the test found it before a single site opened.
