eSource-to-EDC automation
Eliminate duplicate data entry between eSource and EDC
Sites shouldn't enter the same data twice. Nexa Trials automates structured data flow from eSource into your EDC ™ removing manual re-entry, cutting queries, and freeing coordinators to focus on patients.
The problem we solve
Duplicate entry between eSource and EDC slows everyone down
When sites capture data in eSource and then re-enter it into the EDC, the burden compounds across every visit and every form:
- Coordinators spend hours on redundant data entry instead of patient care
- Transcription errors create queries, rework, and monitoring delays
- Data locks slip while teams reconcile mismatches between systems
- Site staff burn out under dual-system administrative load
The result: slower studies, frustrated teams, and data quality risk that shows up too late.
Our solution
Automate the path from eSource to EDC
Nexa Trials removes duplicate entry by automating structured data flow from eSource into your study database ™ with protocol-aligned mapping, validation, and continuous oversight.
When you need more than automation alone, we also provide eSource development bandwidth and centralized QC as part of a phased partnership.
- Full eSource-to-EDC data automation via Nexa Bus™
- eSource development, implementation, and ongoing support
- Centralized QC for hybrid or transitional workflows
- Technology-agnostic integration across leading platforms
Core services
Automation first. eSource support second. QC when you need it.
Our services are prioritized to eliminate duplicate entry first, then strengthen your eSource platform, with QC as a safety net for hybrid workflows.
Full Data Automation
Structured data flows directly from eSource into the EDC ™ no manual re-entry. Automated mapping, protocol-aligned validations, and real-time data in your study database.
eSource Development & Support
On-demand bandwidth for form development, implementation, amendments, and mid-study updates ™ so your eSource platform keeps pace with protocol changes.
Centralized Data Entry QC
For studies still using duplicate entry, our QC team reviews every eSource-to-EDC transfer ™ catching discrepancies early while you transition to full automation.
Phased Automation Roadmap
Start with an automation assessment, layer in eSource support as needed, and use QC as a bridge ™ scaling toward zero duplicate entry at your pace.
Nexa Bus™
The automation engine behind eSource-to-EDC flow
Nexa Bus™ is our technology-agnostic integration layer that receives structured eSource exports and moves them reliably into downstream EDCs ™ eliminating the manual step that creates duplicate entry.
With AI-supported transformation and mapping, Nexa Bus connects leading eSource platforms to EDC systems including Medidata Rave, Veeva, Oracle InForm, Castor, and others ™ without locking you into a single vendor stack.
What automation delivers
- 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
- Lower site workload ™ coordinators focus on patients
- Real-time oversight ™ centralized monitoring across visits

Frequently asked questions
Quick answers about automation, NexaSource™, pricing, and how we work with your existing systems.
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?
We support both paths. Many sites use their existing eSource platform ™ Nexa Bus™ integrates with your stack without replacing your tools. For sites that need a fast, flexible platform, we also offer NexaSource™, our purpose-built eSource with two-week study deployment, protocol-level customization, and seamless EDC integration.
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, Pakistan, and Canada — 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.
What is NexaSource™?
NexaSource™ is our purpose-built eSource platform for clinical research sites that need speed, flexibility, and simplicity. It delivers a clean, intuitive interface, protocol-driven form design, and rapid deployment ™ helping sites move from paper to digital with minimal disruption.
How long does it take to deploy NexaSource™ for a new study?
Most studies can go live in about 2 weeks from kickoff ™ including form build, testing, and go-live. Our team handles setup and validation so your site can focus on patient visits.
Can NexaSource™ be customized for our protocol?
Yes. Every study can be tailored to its protocol ™ from visit structures and CRF logic to sponsor-specific configurations. Built-in validation rules and edit checks help ensure clean data capture from day one.
Does NexaSource™ integrate with our existing EDC?
Yes. NexaSource™ is designed to work alongside your existing EDC workflows. Pair it with Nexa Bus™ automation to move structured source data into your study database without duplicate entry.
Who is NexaSource™ built for?
Sites moving from paper to digital, scaling multiple concurrent trials, or needing faster study startup without overwhelming coordinators. Teams can begin entering data within days ™ not weeks ™ with streamlined workflows built around how sites actually operate.
