Imaging in clinical trials isn’t optional anymore; it’s foundational. In GLP-1 and neurology trials, where ocular endpoint sensitivity is everything, the quality and timing of imaging can directly affect trial speed, cost, and efficiency. Yet it can still be treated as an afterthought.
This article will discuss imaging applications and how early strategy decisions shape downstream success. It’s the starting point for building imaging into your protocol, not around it.
Imaging use in trials has doubled and is growing. That’s because today’s trials require:
With GLP-1 trials under the microscope for ocular safety and neurology trials relying on retinal and optic nerve assessments, precision imaging isn’t just a diagnostic tool; it’s how to protect your ocular endpoints.
Understanding the difference between quantitative and qualitative imaging is essential for designing reliable, regulator-ready clinical trials.
Quantitative imaging provides objective, numerical data captured at the point of acquisition, making it ideal for tracking small but meaningful changes over time.
Qualitative imaging, on the other hand, relies on interpretation and requires strict protocols to ensure consistency across sites and readers.
In trials where imaging supports safety, efficacy, or primary endpoints, as in GLP-1 and neurology studies, applying the correct standards from day one helps reduce variability, improve data quality, and support faster, cleaner trial execution.
Quantitative Imaging
This includes OCT, fMRI, and DEXA. These tools give you measurable numbers—retinal thickness, brain activity, bone density—right at acquisition. Accuracy is everything here. One calibration error can skew results and trigger rework across sites.
Qualitative Imaging
Relies on interpretation. Think CTs, chest X-rays, fundus photos. Without standardized grading protocols, interpretation varies wildly. Note: AI is blurring the line between qualitative and quantitative imaging.
Takeaway: Without standardization, you risk inconsistent data, missed endpoints, and added review cycles.
In clinical trials, the reliability of imaging data hinges on two core principles: precision and accuracy. Accuracy ensures that your baseline data reflects actual clinical conditions, while precision ensures that every subsequent measurement is consistent and comparable.
Both are essential when tracking therapeutic impact or identifying safety signals over time. Inconsistent imaging results can lead to misinterpretation of drug effect, unnecessary rescans, or even failed endpoints.
Trials that prioritize both from the start build stronger datasets, reduce regulatory risk, and stay aligned with submission timelines.
You need both. Accuracy ensures you start from the right baseline, while precision helps you track treatment impact over time.
Imaging needs change as trials progress, and so should your strategy. A one-size-fits-all approach increases risk, especially in studies where endpoints are under review.
Aligning imaging protocols with each phase ensures better data continuity, faster insights, and fewer delays.
Sponsors who adapt their imaging strategy early build a stronger foundation for regulatory approval and future label expansion.
Sponsors who delay imaging decisions face:
Prevention beats rescue. Build imaging into the protocol from Day 1.
