Description
Merative Clinical Data Architecture Assessment (2026)
As of January 2026, Merative has successfully transitioned from the monolithic 'Watson' era to a decentralized cloud-native framework. The architecture is now defined by the Merative Data Fabric, which integrates the Zelta platform for clinical development and Merge for enterprise imaging 📑. This shift prioritizes deterministic evidence from Micromedex over the probabilistic black-box reasoning that characterized legacy oncology systems 📑.
Clinical Orchestration & Interoperability
The system utilizes a modular approach to clinical data management, ensuring 21 CFR Part 11 compliance across distributed global sites.
- Zelta Clinical Development: A SaaS-based EDC (Electronic Data Capture) and DCT (Decentralized Clinical Trials) platform that automates study startup through AI-assisted template generation 📑.
- Merge Imaging Cloud: A vendor-neutral archive (VNA) and viewer architecture that employs deep learning for automated cardiac measurements and radiology workflow optimization 📑.
- FHIR R5 Ingestion: Native support for the latest HL7 FHIR resources, facilitating real-time synchronization between hospital EHRs and Merative’s research databases 📑.

Operational Scenarios
- Automated Study Startup: Input: Protocol PDF and site metadata → Process: Zelta AI mapping to standard CDISC templates → Output: Validation-ready electronic Case Report Forms (eCRF) 📑.
- Diagnostic Decision Support: Input: Patient labs (FHIR) and cardiovascular imaging (DICOM) → Process: Micromedex drug-interaction check cross-referenced with automated Merge measurements → Output: Safety-validated treatment recommendation summary for the cardiologist 📑.
Evaluation Guidance
Technical evaluators should verify the following architectural characteristics:
- Legacy Migration Latency: Benchmark the time required for identity resolution when migrating historical oncology datasets from legacy Watson repositories to the Zelta environment 🧠.
- FHIR Synchronization Stability: Organizations should validate the consistency of real-time data propagation from localized EHR gateways to the Merative Cloud under high transaction volumes 🌑.
- AI-Assisted Monitoring: Request technical specifications for Zelta's automated protocol deviation detection to ensure alignment with specific IRB (Institutional Review Board) requirements 🌑.
Release History
Year-end update: Release of the Federated Research Hub. Allows hospitals to train oncology models on local data without sharing patient records, ensuring GDPR compliance.
Launch of the Autonomous Care Pathway generator. AI now proactively suggests clinical trial enrollment and follow-up schedules based on real-time patient lab results.
General availability of the Multi-Omics Advisor. Correlates proteomics and metabolomics with treatment response predictions.
Integration with IBM watsonx.ai platform. Added generative capabilities to summarize thousands of pages of oncology research into concise summaries for oncologists.
IBM sold Watson Health to Francisco Partners. Rebranded as Merative. Shift towards modular decision support rather than 'AI-as-a-doctor'.
Major NLP upgrade. System can now extract insights from unstructured clinical notes and legacy EHR data with 90%+ accuracy.
Launch of Watson for Genomics. Integration of tumor sequencing data to identify actionable mutations and match them with targeted therapies.
Official launch in partnership with Memorial Sloan Kettering (MSK). Targeted at providing evidence-based treatment rankings for 10+ cancer types.
