Campsis Suite

Open-source R package suite for PK/PD modeling, Non-Compartmental Analysis (NCA), and clinical trial simulation.

See Demo See Repository

The Campsis ecosystem is an open-source suite of R packages designed to streamline Pharmacokinetic and Pharmacodynamic (PK/PD) modeling and simulation workflows.

Key Packages in the Suite

campsis: Core simulation engine wrapper using S4 object-oriented design and tidyverse principles.
campsismod: Structural PK/PD model definition and manipulation framework.
campsisnca: Automated Non-Compartmental Analysis integration.
campsismisc: Utility functions and post-processing helpers.

Architecture Highlights

Language-Agnostic JSON API: Native JSON serialization enables external languages (Python, web backends, and AI agent workflows) to interact directly with the Campsis simulation engine.
Backend Compatibility: Seamlessly delegates core ODE solving to proven engines like mrgsolve and rxode2.
Reproducible Workflows: Built to integrate cleanly with the R targets pipeline manager for regulatory and clinical trial simulations.
