- Window of opportunity trials (WOTs) envision a short course treatment before surgery.
- WOTs streamline the drug development process by defining target patient population.
- WOTs can provide information about the molecular changes operated by the treatment.
- In recent years presurgical WOTs have been successfully applied to breast cancer.
- WOTs deserve to be deployed on a large scale basis.
The high attrition rate is a major issue in anticancer drug development. Among the alternative trial designs, presurgical window of opportunity trials envision a short course treatment in the time window between diagnostic biopsy and surgery in a moderately-sized patient population. This approach allows testing therapeutics when pre- and post-treatment tumor tissues are available for comprehensive molecular analyses. The emerging evidence may help define the ability of a given agent to modulate its target(s) and help obtain a broader picture of the molecular changes operated by the treatment. The resulting gain may outweigh the potential harms for patients in the early disease setting. Window of opportunity trials have been extensively applied to breast cancer. Overall, a wider use of these trial designs might lead to the identification of potential responders, ineffective drugs or combinations, and ultimately contribute to enhance the efficiency of the clinical developmental process.
