Welcome to Pumas

Pumas (PharmaceUtical Modeling And Simulation) is a suite of tools to perform quantitative analytics of various kinds across the horizontal of pharmaceutical drug development. The purpose of this framework is to bring efficient implementations of all aspects of the analytics in this domain under one cohesive package. Pumas 2.5 currently includes:

  • Non-compartmental Analysis
  • Specification of Nonlinear Mixed Effects (NLME) Models
  • Simulation of NLME models using differential equations or analytical solutions
  • Deep control over the differential equation solvers for high efficiency
  • Estimation of NLME parameters via Maximum Likelihood, Expectation Maximization and Bayesian methods
  • Automated covariate selection
  • Parallelization capabilities for both simulation and estimation
  • Mixed analytical and numerical problems
  • Simulation and estimation diagnostics for model post-processing
  • Interactive model exploration and diagnostics tools through webapps
  • Automated report generation for models and non-compartmental analysis
  • Global and local sensitivity analysis routines for multi-scale models
  • Bioequivalence analysis
  • Bioequivalence Power computation and sample size determination
  • Optimal design of experiments

Additional features are under development, with the central goal being a complete clinical trial simulation engine which combines efficiency with a standardized workflow, consistent nomenclature, and automated report generation. All of this takes place in the high level interactive Julia programming language and integrates with the other packages in the Julia ecosystem for a robust user experience.

License

Pumas is covered by the JuliaHub EULA. Pumas is a proprietary product developed by Pumas-AI, Inc. It is available free of cost for educational and research institutes. For commercial use, please contact sales@pumas.ai or to know more visit Pumas for Enterprises.

Getting Started: Accessing Pumas

Pumas is available exclusively via the Pumas for Enterprises or Pumas for Academia platform powered by JuliaHub. Once you register for access, the getting started video series will guide you through the platform and help you get started.

Tip

For additional information and resources on using Pumas in the cloud, refer to JuliaHub's documentation. The documentation provides comprehensive tutorials and guides covering essential features. See, for example, the following guide on how to create batch jobs

One can start using Pumas by invoking it from the REPL as below.

using Pumas

To start understanding the Pumas suite of products in more detail, we have our user-friendy notebook tutorials at tutorials.pumas.ai, along with video courses at Pumas Labs. We highly suggest that all new users start with the Onboarding Video Course!

Annotated Table of Contents

Below is an annotated table of contents with summaries to help guide you to the appropriate page. The materials shown here are links to the same materials in the sidebar. Additionally, you may use the search bar provided on the left to directly find the manual pages with the appropriate terms.

Tutorials

These tutorials give an "example first" approach to learning Pumas and establish the standardized nomenclature for the package. Additionally, ways of interfacing with the rest of the Julia ecosystem for visualization and statistics are demonstrated. Thus, we highly recommend new users check out these tutorials before continuing into the manual.

Basics

The basics are the core principles of using Pumas. An overview introduces the user to the basic design tenants, and manual pages proceed to give details on the central functions and types used throughout Pumas.

Model Components

This section of the documentation goes into more detail on the model components, specifying the possible domain types, dosage control parameters (DCP), and the various differential equation types for specifying problems with analytical solutions and alternative differential equations such as delay differential equations (DDEs), stochastic differential equations (SDEs), etc.

Analysis

This section of the documentation defines the analysis tooling. Essential tools such as diagnostics, plotting, report generation, and sensitivity analysis are discussed in detail in this portion.

Noncompartmental Analysis

This section of the documentation covers the use of Noncompartmental Analysis tooling available with Pumas and independently.

Bioequivalence

Bioequivalence analysis is available in Pumas through the Bioequivalence package.
