How nQuery helps your R workflow

Use R for exploratory methods and custom code. Use nQuery for validated calculations, reproducible results, and a submission record regulators trust.

R: Flexible but Complex

Fragmented Workflows

Trial design methods in R are spread across 100s of packages of inconsistent quality, documentation, and support.

Difficult to Share and Review

Requirement for R knowledge creates technical barriers for collaborators to understand and actively engage with your trial design.

Reproducibility and Regulatory Risk

Package updates or deprecation can affect reproducibility, and most R packages lack validation, which increases regulatory scrutiny.

nQuery: Validated and Trusted

One Validated Platform

Consolidated Trial Design Environment

Your entire clinical trial design workflow in one place: power, sample size, adaptive design and simulation in one validated platform. No hunting across packages, version conflicts or reconciling minimal documentation.

Collaborate and Explore

Review Ready Design Documentation

Intuitive spreadsheet format makes trial design accessible to all and easy to communicate. Standardized workflows, reports and plots reduce bottlenecks and allow teams to examine results with greater transparency and accessibility.
