Continuum Clinical

Delivers end-to-end enrollment programs: patient outreach, site engagement and training, referral management, and retention, with a reputation for working closely with site staff rather than around them.

Program-scoped services.

Whatever the structure, convert it to cost per randomized patient before you compare proposals. Cost per referral is the number vendors prefer to quote and the number that tells you least.

• Site engagement is a genuine specialty, not a line item
• Retention and adherence programs
• Experience across large multi-country programs

• Full-service scoping obscures channel-level performance unless you demand it

Worth it when: Multi-site programs where site under-performance, not lead volume, is the problem.

Not worth it when: A single-site study needing a quick digital burst.

• MMG vs Continuum Clinical — Communications-led versus site-engagement-led enrollment.

Ask for the referral-to-randomization ratio on three studies resembling yours, in the same indication and the same countries. If a vendor will not give it, that is the answer. If your enrollment forecast itself is the shaky part, our sister publication Rock Enroll covers forecasting and rescue in depth.
