A Contract Research Organisation (CRO) is any company contracted to provide R&D support across drug development, while a Clinical Research Organisation focuses specifically on planning and running phase 1–4 clinical trials. In practice, many providers use both terms, and capabilities often overlap.
Contract Research Organisation vs Clinical Research Organisation: Brief History
While outsourcing in pharmaceuticals dates back to the mid-20th century, industry usage of “clinical research organisation” became more visible in the early 2000s with the formation of Association of Clinical Research Organization (ACRO), a trade body representing the clinical outsourcing industry. Over the following decades, ACRO has advocated for consistency, quality, and the recognition of its members’ roles in healthcare. The association’s very name underlines how the term “clinical research organisation” became widely used in those formative years, even as many companies expanded beyond trial operations into broader, end-to-end services.
What is a Contract Research Organisation?
A Contract Research Organisation is any third-party company contracted to provide research and development support services anywhere along the drug development lifecycle. Depending on the provider, this can span preclinical work, clinical trial support, laboratories, clinical data and analytics, and commercialisation services. In practice, the scope is broad and often extends beyond these services. Typical services can include laboratories and bioanalysis, biometric services such as clinical data management, biostatistics, and regulatory medical writing, and safety oversight, real world data analysis, data science, technology platforms, biomarker strategy, and commercial support. Sponsors may engage these providers on a project basis, through functional service provision (FSP), or via integrated programme models.
What is a Clinical Research Organisation?
In difference to ‘contract’, and as mentioned earlier, a Clinical Research Organisation focus is a provider that solely specialises in the operations of clinical trials, typically across all clinical trial phases, from phase 1 through to phase 4. Clinical Research Organisations can still perform services that a contract research organisation would perform such as biometric offerings, but It’s scope centres on clinical development and trial operations, typically covering protocol design and feasibility, start-up, site and country selection, patient recruitment, and clinical monitoring.
Contract Research Organisation vs Clinical Research Organisation: How Providers Position Themselves
Large providers increasingly present themselves as life-sciences partners spanning labs, data, technology, and commercial capabilities. Others retain the familiar “CRO” label while focusing on full-service clinical trial delivery or specialising in certain services or therapeutic areas, positioning themselves as a niche provider (e.g. biometrics CROs). In practice, the label follows market positioning more than strict definitions, and many companies fit both descriptions. It is also helpful to distinguish CROs from CDMOs (Contract Development and Manufacturing Organisations). CROs plan and run research, especially clinical trials and related biometrics and safety, whereas CDMOs develop and manufacture drug substance/product, handling scale-up, technology transfer, and GMP production. Some partners offer both capabilities, but they cover different stages of the value chain.
How does Quanticate position itself in the CRO debate?
Quanticate has used both “clinical research organisation” and “contract research organisation” over the years; however, today, we prefer “contract research organisation” because it better reflects our focus on biometrics services rather than full end-to-end clinical operations. We specialise exclusively in biostatistics, statistical consultancy, statistical programming, clinical data management, real world evidence, medical writing, and pharmacovigilance. These are disciplines that turn study plans and raw trial data into inspection-ready, analysis-ready outputs.
Sponsors engage us to strengthen the biometrics core of their programmes; designing estimands and analysis strategies, building and validating data flows, producing SDTM/ADaM and TFLs, and crafting clear regulatory documents that support submissions. We work as a standalone partner or alongside full-service CROs in project-based or FSP models, giving sponsors depth where it matters most—data integrity, methodological rigour, and regulatory-aligned deliverables.
How do companies use these terms in practice?
In day-to-day usage, companies apply the label that best matches their portfolio and buyer expectations. Some emphasise broad, end-to-end capabilities across data, labs, and commercial functions whilst others position around deep, full-service clinical trial delivery with tightly integrated biometrics and pharmacovigilance.
Conclusion
In short, whether you say “contract research organisation” or “clinical research organisation,” the label matters far less than the fit for your programme. Use the comparison points above to match partner scope, governance, and engagement model to your study’s risks and goals, and anchor decisions in current expectations for data integrity, patient safety, and inspection readiness. For UK sponsors, aligning with ICH E6(R3)/E8(R1) and regional guidance helps ensure that whichever partner profile you choose whether it be broad, end-to-end support or deep clinical-ops specialism, you get reliable outcomes and defensible submissions.
Quanticate’s experts bring integrated support across statistical consultancy, programming, clinical data management, medical writing, pharmacovigilance, and more, connecting design, delivery, and analysis to produce inspection-ready results.
