We describe methods for longitudinal monitoring of the efficacy of therapeutics for the treatment of colonic pathologies in mice using a rigid endoscope. This protocol can be readily used for the characterization of the therapeutic response of an individual tumor in live mice and also for monitoring potential disease relapse.

FAQs
Predefined outcomes establish what investigators will measure before comparing intervention groups. These outcomes may include symptom improvement, biomarker changes, or disease control, creating a consistent basis for judging benefit. Establishing them in advance helps connect the analysis to the intervention’s intended effect and supports clearer interpretation when findings are reviewed across treated and control groups.
A control group provides a reference for judging whether changes observed in treated participants are linked to the intervention. Without that comparison, improvement could reflect unrelated changes in patient status or other influences. Comparing predefined outcomes between groups therefore helps distinguish an intervention-related benefit from changes that might also occur without the treatment.
Statistical analysis examines whether differences in predefined outcomes between treated and control groups are consistent with an intervention effect rather than chance. It gives structure to the comparison and supports a more disciplined interpretation of results. In medical research, this analysis helps determine how findings should inform treatment development, therapy comparisons, and regulatory review.
Analyses of efficacy findings can support comparisons among patient groups, allowing investigators to examine whether benefits differ according to patient characteristics represented in the study. This information can reveal populations that appear more likely to experience symptom improvement, biomarker changes, or disease control. Such distinctions contribute to treatment development and more evidence-based clinical decisions.
A typical assessment establishes the intervention’s intended biological or clinical effect, selects predefined outcomes, and compares those outcomes between treated and control groups. Investigators then apply statistical analysis to evaluate whether observed differences support an intervention-related benefit. The resulting evidence can be examined for treatment comparisons, research conclusions, and decisions about further development.
Efficacy assessment is used when researchers need structured evidence about whether an intervention produces its intended effect under study conditions. Its findings contribute to clinical research and treatment development, where investigators compare therapies and evaluate disease-related outcomes. The same evidence can also support regulatory decisions by showing how consistently predefined benefits distinguish treatment from control.
By organizing comparisons around predefined outcomes and control groups, efficacy assessment gives clinicians and decision-makers evidence about an intervention’s demonstrated benefits. Results may describe symptom improvement, biomarker changes, or disease control rather than relying on unstructured impressions. This supports evidence-based care by informing comparisons among therapies and clarifying which patient groups may benefit most.
