How it works

What is X7 Insight EDC

X7 Insight EDC is an electronic data capture (EDC) platform for clinical trials. The study team designs electronic forms (CRFs) and the visit schedule, coordinators enter participant data, monitors verify it against source documents, investigators sign, and data managers lock the database and export data into regulatory formats. Every change is written to an immutable audit trail — you can always answer the question “who, when, and why.”

This guide is written for clinical staff, not programmers. No technical knowledge is required. Readers usually fall into one of three groups:

  • site staff — the coordinator (CRC) enrolls participants and enters visit data, the investigator (PI) signs it with an electronic signature;
  • sponsor staff — the monitor (CRA) reconciles data against source (SDV) and handles queries, the data manager is responsible for cleaning, locking the database and exports, the medical monitor for the review of safety data, and the Study Builder assembles the study design;
  • organization staff — the administrator manages access and tenant modules, and an inspector or auditor views data and the audit trail in read-only mode.

The full “who does what” table is in Roles and access.

Work in a study moves from left to right — from a clean design to a locked, signed, and exported database:

  1. Designpublished
  2. Capturedata entered
  3. Cleaningsigned & locked
  4. Closeout
The study journey: from a clean design to a signed and exported database.

What happens in each phase:

  1. Design. The Study Builder assembles electronic forms (CRFs), code lists, validation rules (edit checks), and the visit schedule (SoA). The design goes through review and approval, then is published. A published version is immutable — this is the foundation of reproducibility. See Study design.
  2. Capture. The coordinator enrolls a participant, opens a visit and a form, and enters values. Editing an already-saved value requires stating a Reason for Change (RfC). See Data entry.
  3. Cleaning. Queries are opened and resolved, the monitor performs source data verification (SDV), the medical monitor performs the medical review, and the coder codes terms. See Monitoring and cleaning.
  4. Closeout. The investigator signs the data, the data manager locks the database (soft → hard lock) and exports a snapshot into regulatory formats. When the protocol is amended, subjects migrate to the new design version. See Signatures, locks, export.
  • “Where am I / what’s next / what can I do.” Every screen answers three questions: breadcrumbs show where you are; status badges and hints show what to do next; the action panel shows what you are allowed to do.
  • Permission = visibility. You see only the buttons and sections you have permission for — how it works.
  • Statuses are independent. A single record has several status “axes” at once: data entry, SDV, queries, signature, lock, medical review. They do not merge into one “overall status” — each is shown as a separate badge.

The full glossary is in the reference section. The essentials to start with:

Term What it is
Study an entire clinical trial
Site a research site (clinic) within a study
Subject a study participant
Visit a schedule point (StudyEventInstance) that forms are attached to
CRF / form an electronic form for entering visit data
Casebook a “visits × forms” matrix for a single subject
Query a question about the data: a discrepancy, clarification, or remark
SDV Source Data Verification — reconciling data against source documents
RfC Reason for Change — a mandatory reason when editing a saved value
Signature an electronic signature over a snapshot of data (designed for the requirements of 21 CFR Part 11)
Lock locking data against changes (soft and hard)
Scope the reach of a permission: study → site → subject → form
Audit trail an immutable log of all changes with a cryptographic chain
Module a package shipped on top of the core (coding, export, RTSM, etc.)
