What is e-Campsis?

  • e-Campsis is the user-friendly web application that puts efficiency, quality, and reproducibility at the heart of your PK/PD and QSP simulations.
  • Whether you’re exploring complex drug responses or optimizing trial designs, e-Campsis empowers you to simulate, visualize, and analyze with confidence.
  • Built on the open-source R package campsis and leveraging mrgsolve and rxode2, e-Campsis lets you export simulations as R code for full transparency and offline reproducibility.

How does it work

1. Register and Start Your Project

Try the free version and start running simulations in minutes. Upgrade to the professional version to unlock the full functionality of e-Campsis

2. Import and Edit a Model

Select and customize a PK or PD model from the library, or import  NONMEM®, Monolix®,  or rxode2 code. Here you can define and adjust the  parameters.

3. Set up your Trial Design

Easily define even complex dosing schedules, study arms, and covariates in just a few clicks.

4. Run the Simulation

Start your simulation with one click. Explore and visualize what-if scenarios in interactive and customizable graphs.

5. Analyze the Results

Evaluate your results using powerful post-porcessing. Derive secondary parameters, NCA parameters and summary statistics with ease… and get a report-ready table.

6. Create Forest Plots

Evaluate and visualize the influence of covariates on any outcome that can be derived from your simulations (Cmax, AUC, RO%, etc.).

7. Sensitivity Analyses

Identify the most influential parameters in your simulation using sensitivity analysis and visualize their impact.

8. Download your Simulation R-script

Download the full simulation script for local execution in R using our open-source packages, and ensure 100% traceability and reproducibility of your simulations.

9. Communicate with your Team

Use the interactive simulations to effectively communicate model simulation and scenario’s with your team.

Forest plots

Forest plots are powerful plots for showing simulation of multiple variables or subpopulations in a single plot. These plots are common in meta-analyses for presenting results of the individual studies or to illustrate the effect of covariates and the overall estimate. e-Campsis allows you to generate forest plots in an easy and user friendly way, maximizing the power of your simulations.

Handling of time-units

e-Campsis will use the time units as defined in your model. However, in settings you can easily define the time units that suits you simulations most. Easily specify the dosing intervals in weeks, the infusion duration in hours, the dosing time in days and the observation time in days. The appropriate units will be shown in trial design and carried forward in the simulations.

Post-processing and summary statistics

e-Campsis allows you to easily derive key metrics of your simulation through non-compartmental analysis, summary statistics or user-defined metrices. All R-code to derive the metrices will be available in a downloadable script of your simulation.

FAQs

Find answers to common question about e-
Campsis and how it can benefit your research

  • Is there a discount of the pro version for academia ?

    We support research at universities and other academic institutions by a significantly reduced subscription fee of 500 Euros per year for up to 5 named users in your research group. No additional discount applies on top of this offer. For teaching we think that the free version should already cover your needs. If not let us know.

  • Is hosting of e-Campsis secure ?

    Yes! We use the shinyapps.io platform by Posit Inc. for hosting e-Campsis. The platform is running on Amazon Web Services (AWS) infrastructure in the us-east-1 region. Access requires authentication of pro and free+ users, with the possibility to use Google or Github credentials including 2FA. The app itself runs in ephemeral containers, which means that no data is stored on the server permanently but only during the length of the session and some short timeout period. Of course, other e-Campsis users have no access to your session data during that time. The pro version allows you to save the state of your session, including the model, parameters and settings, in a project files that you can download to your computer and upload again when you want to continue working on your project. Upload and download is encrypted and secure

  • Is e-Campsis validated ?

    e-Campsis is being developed with quality in mind through object-oriented programming and automatic unit tests of key functions. This drastically reduces the occurrence of bugs and regressions when the software is updated.

    However, e-Campsis is a graphical user interface that facilitates the set-up of simulations and does not do any calculation itself. The actual “work” is done by the open-source packages campsis, campsismod and others in the background. Simulations of almost all library models with campsis – which uses mrgsolve or rxode2 as the back-end simulation engine – have been successfully verified against simulations with NONMEM. In addition, users of e-Campsis pro will have the option to obtain an qualification suite to ensure accurate functioning of campsis packages in their local environment.
