The number of clinical trials per year has dramatically increased in this century, and quality assurance regulations are much tighter. Therefore, clinical data management systems have become necessary tools for ensuring the highest quality of data — a key component to clinical trial success.

Clinical Trial Management Software is a digital system used by hospital institutions, pharmaceutical companies, and biotech laboratories to organize and oversee clinical trials. The software helps with planning, reporting, team and time management, risk evaluation, etc.

According to Gartner, Electronic data capture (EDC) is the electronic acquisition of clinical study data using data collection systems, such as Web-based applications, interactive voice response systems, and clinical laboratory interfaces. Information is stored in EDC applications and used for analysis, or it is transferred to a clinical trial database containing the data from many clinical studies.

Examples of Top EDC Platforms:

Castor EDC



Clinical Trial Management Systems (CTMS) have become a tool capable of providing researchers and data managers with a unified view of clinical trial workflows. Automating data entry and export and creating a single source of truth for research insight became the centerpiece of CTMS solutions.

Examples of Top-Notch CTMS Vendors:



Randomization & Trial Supply Management (RTSM) is the umbrella term for the various technologies that allow a study team to enroll patients, randomize participants, and manage drug supply ordering. This includes Interactive Voice Response Systems (IVRS), Interactive Web Response Systems (IWRS), and Interactive Response Technology (IRT).

Examples of RTSM:



IRT platforms are large-scale platforms designed to bridge the gap between treatment centers, researchers, and sponsors. These solutions help streamline patient management, assist in drug randomization and supply control. Clinical trial teams use IRTs for inventory management, reliable reporting, and ensuring drug reconciliation.

Examples of IRT:



Clinical trial systems help ensure the transparency and security of medical studies. Tools like EDC, IRT, RTSM and other platforms seamlessly connect patients, researchers, and study sponsors. For a deeper understanding, read our full article using the link below.
