Six stages, from feasibility to close-out.
Every trial we support at a site moves through all six stages — what varies is how long each one takes, depending on the protocol and the patient population.
Site Feasibility Assessment
We review the protocol against the site's actual patient population, staff capacity, and facilities before committing to anything. A significant share of assessments end in a recommendation not to proceed.
Contract, Budget & Regulatory Start-Up
IRB submission, sponsor contract and budget negotiation, and staff GCP training and credentialing all happen in parallel, since any one of them can become the bottleneck if left to run sequentially.
Patient Recruitment & Screening
Chart review and physician referral pathways identify potentially eligible patients, who are then screened against the protocol's inclusion and exclusion criteria — usually the longest single stage of the whole lifecycle.
Active Enrollment & Visit Conduct
Consented patients move through the trial's actual visit schedule, which can run anywhere from a few weeks to several years depending on the protocol's design.
Data Management & Monitoring
Case report forms, source document verification, and internal quality checks run continuously alongside enrollment, ahead of the sponsor's own periodic monitoring visits.
Close-Out & Archival
Once the site's participation ends, records are reconciled, queries closed, and documentation archived to the retention standard the protocol and sponsor require.
