Since 2022, the Clinical Trial Regulation (CTR, EU 536/2014) has applied to all new clinical trials in the EU. The regulation requires uniform procedures, strict deadlines, full traceability and secure data processing, a major change for many organisations, especially when existing software wasn’t designed with CTR compliance in mind.

The choice of your clinical research software is critical. Not just for data processing, but for ensuring consistent workflows, documentation, monitoring and reporting in line with the CTR. Using disconnected systems that don’t integrate well increases the risk of errors, delays and compliance failures.

The CTR (EU 536/2014) replaces the Clinical Trials Directive and has been mandatory for new studies since 2022. Its goal: a single harmonised legal framework across the EU for clinical trials with medicinal products.

The five pillars of the CTR are:

1. Uniform submission and approval procedures via the CTIS portal
2. Higher data quality and greater participant safety
3. Transparent documentation and public reporting
4. Centralised communication between sponsors, member states and ethics committees
5. Full traceability of data, documents and decisions

Because the CTR establishes one harmonised legal framework, systems and processes must be set up in a uniform, auditable and consistent way. Clinical research software plays a central role in this, and it starts with choosing the right platform.

The CTR affects the entire research process. Each phase brings its own challenges.

Start-up phase: strong foundation, predictable process

The start-up phase is all about structure, completeness and timely submission. The CTR requires documents to be complete, up-to-date and traceable before submission in the CTIS. That demands a standardised study start-up where nothing is left to chance.

Typical challenges in this phase:

• Compiling a uniform and complete study dossier
• Meeting strict CTR deadlines for CTIS submission
• Clear task and role assignment within the team
• Full version control and demonstrable audit trails
• Predictable workflows that run identically for every study

Conduct phase: correct execution and real-time insight

During an active study, the CTR demands demonstrable monitoring, secure personal data processing and continuous data quality management. Every deviation must be recorded and every change must be traceable.

Typical challenges in this phase:

• Risk-based monitoring
• Accurate recording of protocol deviations, SAEs and queries
• GDPR-compliant data processing and EU-based storage
• Collaboration across multiple sites working locally
• Continuous data quality oversight without manual checks

Close-out phase: complete, traceable and audit-ready

In the close-out phase, the CTR assesses whether the complete study dossier meets requirements for archiving, reporting and transparency. Auditors expect documentation to be complete, logically structured and immediately accessible. Organisations that start cleaning up too late run serious risks.

Typical challenges in this phase:

• Compiling the final complete study dossier
• Submitting CTR reports to the CTIS on time
• Exportable audit trails for inspectors
• Transparency at study and site level

Good software must not just support the CTR, it must actively help you work compliantly. Use this checklist when evaluating software:

• Standardised workflows: the platform must support study start-up, monitoring and close-out in a flexible yet uniform way.
• eTMF based on the TMF reference model: documentation meets CTR and GCP requirements, including completeness checks and version control.
• Full audit trails: every change is automatically recorded with timestamp, user and description.
• Risk-based monitoring: dashboards, deviation tracking, tasks and safety alerts are essential.
• GDPR-compliant data processing: EU hosting, encryption and role-based access are basic requirements.
• Multi-centre support: local sites work independently while sponsors maintain central oversight.
• Task and deadline management for CTIS: the CTR operates on hard deadlines. Software must help track them.

Common misconception: ‘our current tools are good enough if we build manual processes around them.’ In practice, this leads to errors, duplicate work and compliance risks, especially during audits and CTIS submissions.

The Clinical Research Suite supports CTR requirements across every study phase by making workflows, documentation, monitoring and reporting consistent, secure and fully traceable.

Start-up phase

Standardised CTR workflows in the CTMS. The CTMS supports the complete CTR start-up process with pre-configured, flexible workflows. Every study starts the same way, fully CTR-compliant.

eTMF based on the TMF reference model. The eTMF is pre-configured with the correct categories and document types, producing a uniform dossier that aligns directly with auditor expectations.

Completeness checks and CTIS deadlines. eTMF filters show exactly which documents are missing. Deadline settings in the CTMS and eTMF automatically remind teams of upcoming CTIS submission dates.

Task assignment and notifications. Tasks are assigned to specific team members. Automated reminders keep everyone informed of outstanding actions.

Full version control and audit trails. Every document change is automatically recorded, including revisions and timestamps, ensuring traceability in line with GCP and CTR requirements.

Conduct phase

EDC with automatic validations and query management. The EDC automatically generates queries for inconsistencies or missing data. Investigators resolve these within the same environment. Monitors can raise their own queries, keeping data quality under continuous supervision.

Risk-based monitoring via CTMS and EDC. The EDC is the primary source of all study data: safety events, protocol deviations and queries are recorded here. The CTMS uses this data to support monitors with operational oversight. In one dashboard they see:

• new or open safety events
• protocol deviations
• progress per site and study
• monitoring and follow-up tasks

Because all deviations are recorded centrally, the CTMS can clearly show where risks emerge and where action is required. The result: faster issue detection, fewer manual checks and a data-driven monitoring approach.

GDPR-compliant data processing. All modules run within the EU and comply with GDPR requirements.

Multi-centre collaboration. Local sites manage documents via eISF; sponsors maintain central oversight via the eTMF.

Close-out phase

Completeness dashboards for the final dossier. Dashboards combine data from all modules and show at a glance:

• documentation completeness per site or study
• which documents are still missing
• current compliance status
• outstanding actions needed to close the dossier

Teams can identify gaps early, take targeted follow-up action and deliver an audit-ready final dossier.

Exportable audit trails. All audit trails in the CTMS, EDC, eTMF and eISF are exportable. Auditors can see exactly who made which changes.

Reports for CTIS and audits. Reports provide insight into progress, safety events, open queries and document status at study and site level, ensuring teams are always ready for a CTIS submission or inspection.

Transparency at every level. Role-based permissions give everyone, including external inspectors where required, secure access to relevant data.

The CTR sets high standards for every phase of clinical research. Software must therefore standardise processes, keep documentation accessible and guarantee data security.

The Clinical Research Suite aligns seamlessly with these requirements, helping organisations work CTR-proof: efficiently, securely and with full traceability. Not as an extra layer, but as an integrated foundation.
