Priority 1
Full data automation
Our primary focus: remove duplicate entry by automating structured data flow from eSource into your EDC.
Full Data Automation (eSource ? EDC)
Our automation engine removes the need for sites to re-enter data from eSource into the EDC. Structured data flows directly from the source system into the study database with automated mapping, protocol-aligned validations, and continuous oversight.
- No duplicate entry ? data captured once in eSource
- Faster EDC readiness ? no waiting for site transcription
- Fewer queries ? errors caught before they reach the EDC
- Real-time data in your study database across visits and forms
Nexa Bus? Data Integration
Nexa Bus? is the automation engine behind our eSource-to-EDC integrations ? a technology-agnostic layer that receives structured eSource exports and moves them reliably into downstream EDCs with AI-supported transformation and standardized mapping.
- Compatible with leading eSource and EDC platforms
- Consistent data flow without vendor lock-in
- Centralized monitoring and quality oversight
Priority 2

- Dedicated eSource developers and QA testers per study
- Responsive, detail-oriented builds aligned with your standards
- Flexible ramp up or down for new builds and amendments
- Reliable coverage for mid-study updates
eSource Implementation
Implementing an advanced eSource platform requires clinical insight, operational understanding, and regulatory rigor. Nexa Trials ensures your implementation delivers value from day one.
- Configuration matched to protocol, workflows, and site realities
- Structured training and hands-on adoption support
- Integration with EHRs, laboratory platforms, and EDC systems
- Full compliance with 21 CFR Part 11 and electronic record regulations
Protocol-Driven eSource Design
We transform detailed study protocols into intuitive, visit-aligned eSource designs that sites can execute efficiently and consistently.
- Clear conversion of protocol requirements into digital workflows
- Precise field mapping, visit schedules, and metadata configuration
- Advanced conditional logic to enforce protocol rules automatically
- Designs optimized for usability and high-quality data capture
Custom Form Development
End-to-end custom form development in eSource, tailored to your study's unique requirements ? from requirements and design through deployment and updates.
- Intelligent conditional logic, edit checks, and validations
- Dynamic behavior and data reuse across visits
- Alignment with CDISC/ODM standards and audit trails
- Mobile-friendly layouts for busy site staff
Advanced Scripting & Customization
Our scripting expertise enables sophisticated, study-specific behavior within eCRFs ? improving accuracy and efficiency at the point of capture.
- Dynamic field behavior based on subject data
- Custom clinical validations and logical value relationships
- Automatic calculations (BMI, dosing, time intervals)
- Cross-form and cross-visit consistency checks
Back-Office Operations Support
Nexa Trials acts as an extension of your study team, providing dependable operational support throughout the trial lifecycle.
- Study document generation and maintenance
- Visit tracking, reconciliation, and operational oversight
- Real-time issue resolution and ongoing study support
- Sponsor and site communication assistance
Priority 3
Centralized data entry QC
For studies still using duplicate entry, QC provides a safety net while you transition to full automation.
Centralized Data Entry QC
We provide a dedicated QC layer for studies where sites perform duplicate data entry from eSource into the EDC. Our team reviews every entry across all sites to ensure accuracy, consistency, and alignment with CRF structure, protocol requirements, and data-management expectations.
- Specialized QC analysts assigned to your study
- Fast turnaround and clear discrepancy reporting
- Consistent oversight across all visits and forms
- Reduced site burden with early issue detection
Additional services
Data migration & cleansing
Data Entry, Cleansing & Migration
Reliable data services at every stage ? transforming legacy study data into clean, compliant, analysis-ready datasets.
- Migration of legacy or external datasets into modern systems
- Data cleansing, reconciliation, and structural alignment
- Validation for high-quality, analysis-ready datasets
Engagement model
Automation first, then scale
We start by assessing your eSource-to-EDC duplicate entry workflows and automation potential. eSource development support and QC layer in as needed ? so you move toward zero duplicate entry at your pace.
Automation Assessment
Map eSource fields to EDC structures and identify the fastest path to eliminate duplicate entry.
eSource Development & Support
Strengthen eSource forms and workflows so automation has clean, protocol-aligned data to work with.
Centralized QC
Bridge hybrid workflows with QC oversight while automation rolls out across visits and sites.
Ongoing Support
Continuous automation monitoring, eSource updates, and QC as needed across amendments and new studies.
Pricing and engagement details are outlined in a mutually executed service agreement.
FAQ
Frequently asked questions
How long does it take to set up data automation for a study?
Most studies are ready in about 2 weeks from kickoff to go-live. Timeline can vary based on protocol complexity and how your eSource and EDC are configured.
What does it cost?
Every study is different ? contact us for a custom quote. Rest assured: our engagements are structured to cost less than your current duplicate-entry overhead.
Do you bring your own eSource tool?
No. We use what you already have ? your eSource platform, your CRF design, and your EDC. Nexa Bus integrates with your existing stack; we don't replace your tools.
Which EDC and eSource platforms do you support?
Nexa Bus is technology-agnostic. We integrate leading eSource platforms with EDC systems including Medidata Rave, Veeva, Oracle InForm, Castor, and others ? without locking you into a single vendor stack.
Can you help with a study that's already underway?
Yes. Many engagements start mid-study. We assess your current eSource-to-EDC workflows, map fields to your CRF, and roll out automation ? or layer in QC and eSource support while you transition.
What is Nexa Bus?
Nexa Bus is our integration engine that receives structured eSource exports and moves them reliably into your EDC with protocol-aligned mapping and validation ? eliminating the manual re-entry step between systems.
Will automation disrupt site workflows?
No. Sites continue capturing data in eSource as they do today. Automation removes the second step ? re-keying into the EDC ? so coordinators spend less time on admin without changing how they see patients.
We're not ready for full automation yet. Can you still help?
Absolutely. Our phased model lets you start with an automation assessment, add eSource development support as needed, and use centralized QC as a bridge for hybrid workflows until you're ready to scale.
Who do you work with?
We partner with clinical research sites, sponsors, and CROs across the United States, Europe, the GCC, and Pakistan ? from single-site studies to multi-site portfolios.
Is automated data compliant and audit-ready?
Yes. Automated flows are built with protocol-aligned mapping, validation rules, and audit trails from day one ? aligned with 21 CFR Part 11 and electronic record requirements for inspection readiness.
