As medicine shifts towards a precision oncology approach, clinical trial designs must also evolve. The umbrella trial is an innovative and efficient “master protocol” design that moves away from the one-size-fits-all model. For PharmD students, understanding contemporary trial designs like the umbrella trial is essential for interpreting modern clinical literature and appreciating how targeted therapies are developed for specific patient subpopulations based on their molecular profile.
1. What is the defining characteristic of an umbrella trial design in precision medicine?
- It tests a single therapy in patients with different types of diseases that share a common molecular alteration.
- It tests multiple targeted therapies simultaneously in patients who all have the same type of disease but different molecular alterations.
- It tests a single drug against a placebo in a broad, unselected patient population.
- It focuses on dose-finding and safety in a small group of healthy volunteers.
Answer: It tests multiple targeted therapies simultaneously in patients who all have the same type of disease but different molecular alterations.
2. In an umbrella trial, how are patients typically assigned to different treatment arms?

- Based on their tumor’s specific genetic mutation or biomarker status
- Based on their age and gender
- By patient choice
Answer: Based on their tumor’s specific genetic mutation or biomarker status
3. An umbrella trial is designed to study multiple drugs within a single:

Answer: Efficiency in testing multiple targeted drugs under a single “master protocol”
5. How does an umbrella trial differ from a basket trial?
