The team behind nQuery

The complete trial design platform to make
clinical trials faster, less costly and more successful

nQuery Logo-WithQualifier

Statsols is the company behind nQuery. nQuery is the complete trial design platform to make clinical trials faster, less costly and more successful.

For over 20 years, we have worked with biostatisticians and researchers all over the world to ensure they meet their regulatory requirements and make clinical trials as efficient and ethical as possible.

nQuery covers all phases (I - IV) and all types of trial designs (classical to adaptive). In 2021, 88% of organizations with FDA approved clinical trials used nQuery for their study designs.

Founded in 1984, our business began as a subsidiary of Californian software company, BMDP Statistical Software Inc. As the BMDP subsidiary, we grew and developed overseas markets for BMDP and then later, through a management buy-out, formed Statsols.

In 2022, Statsols became part of Dotmatics, the world’s largest and most powerful scientific R&D software platform. Combining an open data informatics framework with best in breed applications like Statsols, we offer the first true end-to-end solutions for biology, chemistry, formulations, data management, flow cytometry, and more. Together, our company can better: connect science, data, and decision-making and ultimately drive meaningful transformation for our customers.

Our Mission
Together we can accelerate scientific innovation to make the world a healthier, cleaner, safer place to live
