Frequently Asked Questions

What are the essential features of custom clinical trial platforms?

Core features include EDC, CTMS, ePRO/eCOA, eConsent, RTSM, open APIs, compliance tooling, audit trails, and remote monitoring. EDC systems are central to modern clinical trials, enabling real-time oversight and faster database locks (see PharmiWeb’s 2026 EDC roundup).

How does AI improve clinical trial platform performance?

AI automates R&D workflows, optimizes protocols, powers real-time risk monitoring, and delivers predictive analytics for data quality and enrollment. In benchmarks, DIP reported up to an 18% outperformance in R&D automation and multi-agent accuracy versus peer models, signaling tangible gains for AI-native platforms.

What compliance standards should clinical trial platforms meet?

Expect 21 CFR Part 11, ICH-GCP, HIPAA, GDPR, ISO 27001, and SOC attestations at a minimum. Modern EDC platforms typically provide validated audit trails, encryption, and controls mapped to ICH-GCP and Part 11 requirements 

How do platforms support decentralized and hybrid clinical trials?

They enable remote eConsent, telehealth/televisits, ePRO/eCOA, and distributed eSource with secure data flows and monitoring. For example, Viedoc’s cloud-native suite bundles EDC, ePRO/eCOA, eConsent, and televisits to operationalize decentralized studies, increasing reach and reducing participant burden.

What factors should sponsors consider when selecting a custom platform?

Prioritize interoperability (BYOT and APIs), published compliance certifications, measurable efficiency benchmarks, and modular pricing; then validate vendor support, case studies, and integration fit via hands-on demos. 2026 market predictions emphasize AI fluency with governance and outcomes-based metrics as selection differentiators.

Do these platforms align with FDA guidance on eSource and eConsent in the U.S.?

Yes. Leading platforms provide audit trails, identity verification, Part 11–compliant electronic signatures, and role-based access to meet FDA expectations for eSource and eConsent. Sponsors should document system validation and follow site/SOP controls to ensure inspection readiness.

How do platforms integrate with U.S. EHR systems like Epic and Cerner using FHIR?

Most vendors support HL7 FHIR R4, HL7 v2, and C-CDA/CCD, with SMART-on-FHIR or app-launch workflows for context. Some offer certified apps in EHR marketplaces (e.g., Epic Connection Hub) and prebuilt mappings to streamline demographic, medication, and lab data exchange.

What cloud and data residency options do U.S. sponsors typically require?

Common options include HIPAA-eligible services on AWS, Azure, or Google Cloud with U.S.-only data storage, SOC 2 Type II and ISO 27001 controls, database encryption, and customer-managed keys. Certain programs may require AWS GovCloud or FedRAMP-authorized services.

How do platforms address U.S. privacy laws beyond HIPAA (e.g., CCPA/CPRA)?

Vendors typically offer DPAs/BAAs, configurable consent and notice workflows, data minimization, role-based access, logging, and processes to support data subject requests. Many provide regional data segregation and configurable retention to accommodate state-specific obligations.

How can platforms help sponsors meet the FDA Clinical Trial Diversity Plan expectations?

Capabilities often include diversity-aware feasibility (e.g., ZIP-code level insights), multilingual eConsent and ePRO, accessibility features, community-site enablement, and enrollment analytics by demographics, plus reporting that supports Diversity Plan documentation for submissions.
