Highlights
Clinical trials generate vast amounts of biological and physiological data, creating a rich source of evidence for understanding disease mechanisms, treatment effects, and patient outcomes. From patient-reported outcomes and case report forms to biological samples and connected devices, clinical trials rely on a diverse range of data sources to capture evidence across the patient journey. Data capture is increasingly becoming efficient process, but generating actionable insights remains challenging because data often resides in fragmented systems and organisational silos. Naturally, no clear picture emerges of the overall disease and the patient’s journey. The disparate evidence has potential only when a patient-centric foundation can link these disparate data sources. Only when this is achieved can clinical, data science, and safety teams move past manual data preparation and cleaning and focus on the main drivers of drug development – the patient sub-groups responding to therapy, the reasons they do so, as well as how safer drugs can be designed with improved quality in the subsequent phases.
The problem is not the massive amounts of data collected. The root causes can be attributed to five operational friction points that divide the patient’s journey into isolated compliance and storage pockets. This is illustrated in the figure below (Figure 1).
Multi-model complexity can be resolved without needing to overhaul existing tools via a unified patient-focused architecture (Figure 2).
that uses metadata to stitch trial data together. The subject universal Id and visit Id enable the aligning of heterogeneous data streams across both identity and time wherein imaging, genomics, clinical, operational, and digital biomarker data are interpreted as part of one coherent participant record. This allows source formats to be preserved where necessary with imaging aligning with DICOM and genomics retaining Global Alliance for Genomics and Health (GA4GH) or VCF structures. Also, clinical data can remain aligned with CDISC or Observational Medical Outcomes Partnership (OMOP) patterns while device data retaining its time-series character. From isolated downstream steps, this architecture frames metadata cataloguing, governance, and compliance within cross-cutting wrappers.
The different layers are explained below:
Source systems: The architecture connects directly to the key systems that support a clinical trial, bringing together imaging data from Picture Archiving and Communication System (PACS)/Vendor Neutral Archive (VNA) platforms, genomic data from VCF, Binary Allignment Map (BAM), and CRAM pipelines, high-frequency streams from wearable and electronic Clinical Outcome Assessment (eCOA) platforms, and core clinical data from systems such as EDC, Clinical Trials Management System (CTMS), Clinical Data Management System (CDMS), and Lab Informatics Management System (LIMS).
Ingestion and edge de-identification: Before data enters the platform, modality-specific gateways verify formats, apply privacy safeguards, and enforce quality checks. Whether processing DICOM images, genomic files, or continuous data from wearables, these controls help ensure that the data is secure, compliant, and ready for downstream analysis.
Common metadata and catalogue layer: This layer establishes a trusted view of data across the platform. A Master Subject Index links local identifiers to a common subject_uid, while the catalogue captures schemas, lineage, and mappings to standards such as MedDRA and LOINC, making data easier to find, trace, and reuse.
Storage layer (multi-modal lakehouse): Data progresses through three layers in the lakehouse. Raw source files are retained in Bronze, validated and standardised data is managed in Silver, and analysis-ready datasets and reusable ML features are curated in Gold. This structured approach improves traceability, reduces preparation effort, and makes high-quality data readily available for research and analysis.
Governance, security and compliance: Consent-aware access control and automatic masking when patients withdraw consent, immutable 21 CFR Part 11 audit logging, PII disclosure risk monitoring, and dataset version control strengthen governance, security and compliance credentials through an active compliance wrapper.
Consumption and analytics layer: Standardised presentation layer exposing APIs, ML workbench feature stores, automated radiomic extraction engines, and optimised JDBC/ODBC connections for traditional biostatistics platforms (SAS, R, etc).
A unified multi-modal foundation can accelerate clinical insight generation by reducing the time teams spend reconciling disconnected files and preparing data for analysis. By linking governed, reusable datasets and features through consistent subject_uid and visit_id identifiers, researchers gain a unified view of patient data across modalities and studies. Clinical scientists can create more complete patient cohorts, biostatisticians can work with traceable, analysis-ready data, and data scientists can reuse validated feature pipelines, replacing the extraction-logic pipelines for every study. The result is a more efficient and trusted analytical environment that enables faster, more reproducible research.
These benefits extend systematically across the trial lifecycle:
Modernising clinical infrastructure does not mean huge expenditure. The overhauling can be done in tandem with legacy systems and without disrupting active trials.
Early value and minimised operational friction can be ensured with a staged rollout in place:
What is also equally important is when data managers, clinical scientists, and regulatory leads work together early on. There is a greater likelihood of solutions co-designed with study teams aligning with operational realities, which in turn enables sustained adoption.
Organisations that can learn continuously across trials, molecules, and therapeutic areas will emerge successful in drug development. A unified, patient-centric multi-modal data foundation encourages sponsors to adopt an industrialised evidence-generation engine over a reactive, study-by-study data assembly. As machine learning, real-world evidence (RWE), and precision medicine become foundational to pipeline strategies, this integrated approach moves from an operational advantage to a regulatory and clinical necessity. Hence, a multi-modal data foundation is the answer towards securing the agility, auditability, and scientific precision needed to bring life-changing therapies to patients faster.
