COSA Spotlight Q4 2025

Join CDISC and Open-Source Developers for the COSA Spotlight Webinar on 9 December. Register to hear from open-source developers in the CDISC community as they showcase their free tools as part of the CDISC Open Source Alliance (COSA).

Hear presentations on:

• USDM OSB Uploader (Chaitanya Repaka from AI Lens SA): Setting up clinical trials and managing study designs is often manual, time-consuming, and prone to errors. The USDM OSB Uploader automates this process by seamlessly integrating USDM files with OSB platforms, allowing full study uploads or modular handling of study components. It includes built-in validation, error handling, and type-safe operations to ensure accuracy and consistency, saving study teams significant time while reducing manual effort.
• SAS Dataset-JSON (morioka　森岡 yutaka 裕, EPS Holdings Inc and Yuki Nakagawa, EPS): The sas_dataset_json package converts SAS datasets to Dataset-JSON and back, using SAS extended attributes to capture all necessary metadata. Although it’s built entirely in SAS, it gives users precise, flexible control for creating and reading Dataset-JSON files.
• aNCA (Gerardo José Rodríguez Alarcón, Roche): The aNCA package enables users to perform full Non-Compartmental Analysis (NCA) without any coding, automatically generating PP, ADPP, TLGs, and other outputs based on user-defined settings. Designed for pharmacometricians, clinical pharmacologists, preclinical scientists, and regulatory teams.
• SoA Workbench (Darren Moreland, CDISC): The SoA Workbench addresses a gap in clinical study design: the lack of a user-friendly interface to build a Schedule of Activities and generate valid, standard-conformant USDM v4.0 outputs. This Python-based web application allows teams to create, edit, and version SoAs across multiple studies. Users may link activities to CDISC Biomedical Concepts, and run diff reports for impact analysis. Designed for clinical programmers, protocol developers, and medical writers, the tool is actively developed in GitHub, where contributions, issue reporting, and code reviews are fully supported.
