Master Protocol (Basket / Umbrella / Platform) [All terms](/terms) Clinical & Trials [Clinical Evidence](/ecosystems/clinical-evidence) # Master Protocol (Basket / Umbrella / Platform) A single protocol that evaluates multiple interventions, populations, or sub-studies under a unified statistical and operational framework. Reviewed by [Christian Espinosa, Founder, Blue Goat Cyber](/authors/christian-espinosa) Last reviewed May 9, 2026 ## Definition A master protocol is a single overarching trial protocol that simultaneously evaluates multiple interventions or populations: basket trials test one therapy across multiple diseases sharing a common biomarker; umbrella trials test multiple therapies in a single disease stratified by biomarker; platform trials evaluate multiple therapies against a common control with sub-studies that can drop or add over time. The architecture reduces administrative overhead, shares control arms, and accelerates evidence generation. What the regulation says FDA Guidance: 'Master Protocols: Efficient Clinical Trial Design Strategies to Expedite Development of Oncology Drugs and Biologics' (March 2022). NIH and the FDA-NIH Joint Leadership Council have published companion playbooks. ## What this means in practice Master protocols originated in oncology and have spread to neurology, infectious disease, and increasingly device evidence generation ( [companion diagnostic](/terms/companion-diagnostic) studies, multi-arm imaging AI evaluations). Common pitfalls - • Underestimating the operational complexity, master protocols simplify design and complicate execution. - • Failing to define add/drop rules and DSMB authority precisely up front. ## Related terms Grouped by theme ### Editor's picks · Hand-selected related concepts [ Clinical & Trials Adaptive Trial Design Trial design that pre-specifies opportunities to modify aspects (sample size, arms, endpoints) based on interim data. ](/terms/adaptive-trial)[ Clinical & Trials Bayesian Trial Design Trial design that uses Bayesian statistics, often incorporating prior data from related studies or registries. ](/terms/bayesian-trial)[ Clinical & Trials Data Safety Monitoring Board(DSMB) Independent committee that periodically reviews accumulating safety and (sometimes) efficacy data during a trial. ](/terms/dsmb)[ Clinical & Trials Pivotal Trial Definitive clinical study designed to establish safety and effectiveness for marketing authorization. ](/terms/pivotal-trial) ### More in Clinical & Trials · Same category [ Clinical & Trials Adverse Event(AE) Any untoward medical occurrence in a subject, whether or not related to the device. ](/terms/adverse-event)[ Clinical & Trials ALCOA+ Data integrity principles: Attributable, Legible, Contemporaneous, Original, Accurate (plus Complete, Consistent, Enduring, Available). ](/terms/alcoa-plus)[ Clinical & Trials Analytical Sensitivity An IVD's ability to detect small quantities of an analyte. ](/terms/analytical-sensitivity)[ Clinical & Trials Blinding and Masking Procedures that hide treatment assignment from patients, investigators, or assessors to reduce bias. ](/terms/blinding) Cited by Where this term appears across MedTech Terms.
