Radiotherapy Signal Analysis
Signal
Protect trial outcomes by identifying radiotherapy-driven variability that can obscure drug effects.

For Sponsors
Separate Signal from Noise
Distinguish drug effects from radiotherapy-driven variability in efficacy and toxicity so outcomes are easier to interpret and defend
Surface Treatment Variability
Identify radiotherapy planning and delivery patterns across sites and cohorts, including outliers that may influence trial interpretation
Understand Unexpected Results
Provide context for unexpected efficacy or toxicity signals by examining radiotherapy execution alongside clinical outcomes
Complements RTQA
Signal does not replace RTQA. It provides surface-level analysis to protect interpretability when full RTQA is impractical or unavailable
During the Trial
Prospective and Retrospective
Enable early detection of emerging patterns and deviations, not just post-hoc explanations
Continuous Improvement
Early visibility enables feedback to sites, improving consistency while the trial is still underway
Low Burden by Design
Lightweight by Default
No central plan approval, no protocol gatekeeping, and no heavy compliance process
Minimal Site Disruption
Designed to fit alongside existing trial workflows without slowing enrollment or treatment delivery
Why Signal Matters
Protect interpretability
Ensure trial results are not driven by avoidable radiotherapy variability
Detect true drug effects
Reduce outcome noise that dilutes treatment differences and improve the likelihood of detecting a real signal
Strengthen credibility
Document consistent backbone therapy delivery for regulators, HTA bodies, and guideline panels
