Study Lifecycle: Create, Plan & Activate

State Flow

A study goes from creation to activation:

StateMeaningKey actions
CandidateCandidateConfigure + Plan Study
PlanningPlanningMilestones and EDL expand
ActiveActiveEntered via Ready to Enroll; sites can be initiated

Creating a Study

Open the Studies list → Create, fill in Study Number and Study Phase (e.g. Phase III), and save. The study is created in the Candidate state.

Configuring & Running Plan Study

  1. Open the study detail page → Study Configuration Details:
  2. Milestone Master Set and Template EDL are required.
    • Recruitment Planning Metrics: check Screened, Enrolled (optionally Randomized).
      • Recruitment Planning Frequency: e.g. Monthly.
        • Recruitment Planning Level: e.g. Study.
          • Metric Calculation: Date-Based.
    • All Actions → Plan Study, fill in Study Start Date, submit. The state becomes Planning; study-level milestones and the EDL are generated.

    Filling Recruitment Milestone Dates

    Before Enrollment Metrics Over Time can be generated, fill in the finish dates of the paired milestones for each checked recruitment metric:

    MetricFirst milestoneLast milestone
    ScreenedFirst Study Subject ScreenedLast Study Subject Screened
    EnrolledFirst Study Subject InLast Study Subject In

    For each milestone: Plan Milestone (if Unplanned) or Edit, and fill in Planned Finish Date.

    Note

    Last must be ≥ First, otherwise the metric generates no Metrics Over Time. Use the study-level entries, not site-level ones with similar names.

    Setting Enrollment Metric Planned Values

    The study is seeded with Enrollment Metrics (e.g. Total Screened / Total Enrolled). Open each record → Edit, and set Planned to the target number (e.g. Screened=100, Enrolled=80). Planned > 0 is one of the gates for Metrics Over Time.

    Plan Subject Recruitment

    Study detail page → All Actions → Plan Subject Recruitment; the Enrollment Metrics Over Time section then shows monthly Screened / Enrolled records. The action is idempotent — running it again adds no records.

    Activating the Study

    All Actions → Ready to Enroll, submit. The state becomes Active; milestones persist, with new entries like Primary / Final Database Lock typically added. Only after activation can sites run Initiate Site (see Site Lifecycle).

    Troubleshooting

    SymptomSuggestion
    Plan Subject Recruitment produces no Metrics Over TimeCheck the gates: Metric Calculation is Date-Based; recruitment planning config saved; paired milestones have finish dates with Last ≥ First; Total Screened/Enrolled Planned > 0
    Enrollment metrics missingThey appear after Plan Study; check the study detail section or Study Management → Enrollment Metrics
    First/Last Subject milestones missingVerify Plan Study ran and the state is Planning; use study-level entries
