Imaging Rescue and Multimodal Workflow Restoration in a Complex Oncology Clinical Trial

Overview

A global biopharmaceutical company conducting a pivotal oncology trial encountered significant imaging challenges that put the study’s progress and secondary endpoint integrity at risk. Because the trial required specialized subject matter expertise in both ophthalmology and oncology to support accurate tumor characterization, progression assessment, and systemic disease evaluation, the absence of this expertise across the imaging vendors led to misaligned workflows, data gaps, and protocol deviations.

Situation

This complex trial required two distinct but interdependent imaging domains:

• Ophthalmic imaging (fundus photography, OCT, ultrasound B-scan) to assess local tumor characteristics, monitor progression, and evaluate treatment response
• Radiological imaging (CT/MRI/PET) to detect and track metastatic disease across systemic sites

In this program, these modalities were handled by separate vendors, creating fragmented workflows, inconsistent imaging outputs, and gaps that threatened protocol compliance. Because the study depended on precise coordination between ophthalmology and oncology imaging, the lack of integrated oversight resulted in operational instability and risk to key secondary endpoint analyses.

Challenges

The sponsor faced multiple critical issues, including:

• Suboptimal ophthalmic image acquisition and high variability across global sites
• Missing or incompatible datasets that limited evaluability
• Lack of synchronization between ocular and systemic imaging assessments
• Threats to secondary endpoint integrity, requiring aligned multimodal workflows

Voiant’s Integrated Rescue Approach

1. Unified Ophthalmic + Radiological Imaging Framework
   Voiant centralized all imaging operations under a synchronized workflow into one communication plan to ensure aligned visit windows, standardized imaging parameters, harmonized and secured data delivery, and real-time QC oversight.
2. Specialist Site Remediation
   Voiant’s ophthalmic and radiological experts retrained and re-certified sites on the study’s specialized imaging requirements, standardized tumor measurement methods, and expanded certified ophthalmic site capacity — currently certifying 79 sites and providing training to 60 registered sites to ensure consistent, high quality image acquisition across the program.
3. Multimodal Standardization and Read Optimization
   Voiant implemented a unified two tiered read framework that supports consistent tumor measurement across modalities and maintains a robust tumor progression workflow, even when image quality varies across timepoints. To improve submission accuracy and reduce operational friction, Voiant standardized training for both ophthalmic and radiological imaging requirements and streamlined communication between internal teams, external partners, and sites to accelerate QC and ensure timely delivery to the third party radiation plaque vendor. In parallel, Voiant strengthened quality control procedures by aligning QC standards, corrective feedback, and workflow expectations with the plaque treatment vendor’s needs to enable rapid, reliable image transfer while preserving data integrity at every stage.
4. Accelerated Timelines and Read Turnarounds
   Voiant’s rapid-response reading teams reduced turnaround times and restored visibility into disease activity, eliminating delays that were previously interrupting trial flow

Impact

Through coordinated multimodal rescue, Voiant:

• Restored imaging compliance and evaluability across both ophthalmic and oncologic domains
• Unified local tumor assessment and systemic disease monitoring under a single operational structure
• Stabilized timelines and re‑established reliable imaging operations
• Enabled consistent secondary endpoint monitoring across ocular and systemic modalities
• Positioned the sponsor for stronger downstream regulatory-readiness and future oncology development strategy

Conclusion

Voiant’s rescue of this complex oncology trial reflects the growing need among sponsors for specialized imaging expertise, centralized multimodal operations, high‑quality integrated datasets, and reliable stabilization of complex imaging programs. Voiant’s integrated ophthalmic‑radiology model is uniquely equipped to stabilize the integrity of the trial’s imaging endpoints while still maintaining development momentum. With deep experience supporting over 500 studies across oncology and ophthalmology, Voiant serves as a trusted partner for sponsors who require seamless multi-therapeutic integrated imaging expertise, operational precision, and a team well-versed in the demands of complex clinical development.
