What one day of enrollment delay costs a clinical trial

Tufts CSDD puts the direct cost of a Phase III trial at $55,716 per day and Phase II at $23,737. Here are the verified numbers, what changed from the old $4 million figure, and what it means for sites.

Does outreach to referring physicians actually increase trial enrollment?

Published cases show physician outreach can become a site's top patient source, and one study shows a one time education push recruiting no one. Here is what separates outreach that works from outreach that does not.

Behind on enrollment: a recovery plan for clinical research sites

If your site is behind on enrollment, you are not alone: 37% of sites under enroll. Here is a four step recovery plan: diagnose the funnel, re mine records, add a physician referral source, and report weekly.

Recruitment ROI is the per patient revenue a channel produces, minus its cost, divided by its cost. Here is the formula, a worked example, and the mistakes that make channels look better or worse than they are.

Getting community oncologists to refer patients to oncology trials

About 85% of cancer patients are treated in community practices, but community programs enroll just 4.1% of patients in treatment trials versus 21.6% at NCI designated centers. Here is how sites close that gap.
