Clinical Data Operations

A clinical trial generates more documentation than most organisations can manage without dedicated operational support. TMF integrity, data entry accuracy, and audit trail completeness are not incidental concerns — they determine whether your trial data can be trusted by a regulatory authority.

Data flow architecture

From source to submission — how clinical data moves

Understanding data provenance is fundamental to regulatory submission integrity. Every data point has an origin, a handling chain, and a final mapped position in the submission dataset.

S
Source Data
Clinical site source documents. Lab results. ePRO entries. Investigator assessments.
→
E
Data Entry
EDC transcription, query generation, and source data verification.
→
C
CDASH to SDTM
Standards-based mapping, annotation, and derivation programming.
→
A
Analysis Datasets
ADaM dataset creation supporting statistical analysis and submission tables.
TMF Management

Trial Master File — structured to withstand inspection

Zone 01
Trial Management
Core trial governance documentation — protocol and amendments, financial disclosures, delegation logs, and trial team training records. We maintain version control, completeness tracking, and expiry monitoring across all Zone 1 artifacts.
Protocol Amendments Delegation Log Training Records
Zone 03
Regulatory Documentation
Ethics committee approvals, authority correspondences, product dossier for investigational product, and IMP-related regulatory submissions. All documents maintained with approval date tracking and expiry alerts.
IEC/IRB Approvals Competent Authority IMP Dossier
Zone 05
Data Management
Data management plan, CRF design specifications, edit check documentation, data validation reports, and database lock documentation. We support the DM function with operational capacity to maintain TMF completeness through lock.
DMP CRF Specifications Validation Reports Database Lock
Zone 06
Safety Documentation
SAE reports, expedited safety reports to authorities, and safety monitoring committee documentation. Coordination between clinical operations, PV, and regulatory functions to ensure complete and timely safety document filing.

Core deliverables

What our clinical data team produces

01
Data Management Plans
Comprehensive DMP documents covering database design, data collection standards, edit check specifications, QC procedures, and data transfer agreements — aligned to CDISC standards and sponsor SOPs.
02
TMF Management
End-to-end trial master file operations — structure implementation per DIA Reference Model, ongoing completeness monitoring, milestone-driven review, and preparation for close-out and archival.
03
EDC Administration
Electronic data capture system administration — database build support, user access management, query generation and management, and data extraction programming for data transfers and lock activities.
04
CDISC Mapping
CDASH, SDTM, and ADaM standards implementation. Dataset specification writing, mapping documentation, define.xml production, and dataset validation using Pinnacle 21 enterprise tools.
05
Data Quality Management
Ongoing data quality monitoring — query rate analysis, site performance metrics, data cleaning cycle management, and pre-lock cleaning activities to support clean database lock within protocol timelines.
06
Medical Coding
MedDRA coding for adverse events, concomitant medications, and medical history. WHO Drug coding for study medications. Coding conventions documentation and consistency audits throughout the trial.

Data integrity

The integrity of a regulatory submission begins with the first data entry on the first day of the trial — not at database lock.
