What is a CRO in clinical trials?

In the world of drug development, running a clinical trial is a complex, costly, and highly regulated process. To address these challenges, many healthcare companies rely on specialized organizations: CROs, or Contract Research Organizations. Datacapt supplies clinical trial software for CROs, from single-study teams to multi-sponsor operations.

These entities take on all or part of the operational management of a clinical trial on behalf of a sponsor. They play a critical role in the execution of clinical studies worldwide.

Definition and role of CROs

A CRO is an external organization contracted by a sponsor—whether a pharmaceutical company, a biotechnology firm, or a public institution—to conduct all or part of a clinical trial. This collaboration is formalized through a detailed contract that clearly defines each party’s responsibilities.

What types of studies do CROs typically handle? Their scope is broad: Phase I to Phase IV trials, observational studies, bioequivalence studies, as well as trials in oncology and rare diseases. Their expertise spans both single-center studies and multicenter trials conducted across multiple countries.

Zurko Research manages more than 300 studies a year on Datacapt.

Services offered by CROs

CROs provide a wide range of services covering the entire clinical trial lifecycle:

• Protocol design and preparation of regulatory documents
• Site selection and qualification
• Monitoring and on-site data oversight
• Clinical data management and biostatistics
• Pharmacovigilance and adverse event management
• Regulatory submissions to competent authorities

How do CROs add value to the drug development process? By pooling specialized expertise and making skilled resources readily available, they allow sponsors to remain agile without building large internal teams. In addition, CROs often have established global site networks, which helps accelerate patient recruitment and reduce time to market.

Benefits and limitations of working with CROs

Partnering with a CRO offers several clear advantages for sponsors:

• Flexibility: resources scale according to each study phase
• Specialized expertise: access to advanced skills without long-term hiring
• Geographic reach: ability to run trials across multiple countries simultaneously
• Timelines: well-established processes and dedicated teams

That said, some limitations should be considered. Certain CROs focus on specific therapeutic areas, or specialize exclusively in pharmaceuticals or medical devices. Datacapt supports both, including device trials and post-market data.

CROs and regulatory compliance: a close relationship

CROs operate in a strictly regulated environment. They must comply with Good Clinical Practice (GCP/ICH E6), as well as requirements from authorities such as the EMA in Europe and the FDA in the United States, along with local regulations in each country where the trial is conducted.

What should companies consider when selecting a CRO? Key criteria include therapeutic expertise, the robustness of quality processes, transparency in data management, and the ability to operate in targeted geographic regions.

Tools like Datacapt help streamline this coordination and strengthen compliance throughout the study.
