Closing an Enrollment Gap on a Protocol That Could Not Miss Its Timeline
A ZO Skin Health study site needed to reach its enrollment target within a fixed study window. The existing patient pipeline could not sustain the pace the protocol required.
In-house outreach had been considered but not resourced. Commercially available recruitment vendors offered campaign deliverables tied to activity, not to the outcome the site needed: randomized patients. The cost structure made no distinction between campaigns that succeeded and campaigns that did not.
The site required a partner whose financial commitment matched the commitment the site was making to the sponsor.
Feasibility First. IRB-Ready Campaign. Pre-Screened Referrals.
Feasibility confirmed a viable patient population within the site's geographic catchment area. Clinical Enroll developed an IRB-ready campaign, deployed across condition-targeted digital channels, with pre-screening built into the referral process before any patient reached the site's coordinator team. The randomization commitment was formalized in contract before launch.
26 Randomized Patients. $577 Per Randomized Patient.
The campaign delivered 26 randomized patients against a $15,000 investment, a cost per randomized patient of $577. This is the lowest cost per randomized patient in the Clinical Enroll portfolio across all published engagements.
The randomization commitment in the contract meant the site carried no financial exposure if the campaign fell short. The structure was designed around the outcomes the site could report to its sponsor and account for on its own P&L.
How Feasibility Was Verified Before Launch
Clinical Enroll evaluated the ZO Skin Health acne study for feasibility before extending a randomization commitment, modeling the addressable patient population within the site's geographic catchment area against the study's 12-week enrollment window and $15,000 campaign envelope.
- Study design and eligibility review — IGA and Cook's scale assessment criteria confirmed with the study team.
- Addressable population modeling — acne patient density assessed within the site's catchment area.
- IRB-ready campaign build — condition-targeted creative and channels developed for compliance review.
- Pre-screening — every referral is screened against the study's inclusion and exclusion criteria before reaching the site.
- Contracted randomization commitment — the enrollment target is fixed in writing before the campaign launches.
