What is a CRO?
A contract clinical research organization, or CRO, is a company that provides support to the pharmaceutical, biotechnology, medical device and government/academic institutions in the form of research services outsourced on a contract basis. CROs can provide a wide range of clinical trial services to their sponsor clients including clinical development, clinical operations, clinical data management, biostatistics, medical writing and regulatory consulting. By outsourcing clinical research services to a CRO, sponsors are able to realize significant cost and time efficiencies compared to maintaining these capabilities and resources in-house.
Clinical Development Services
When a sponsor outsources clinical development to a CRO, the CRO will assume responsibility for designing the clinical protocol, developing the statistical analysis plan and creating other documents required for regulatory submission and approval. Experienced clinical research associates at CROs have deep expertise in developing clinical protocols that are approvable by regulatory agencies on an expedited basis. They ensure protocols adhere to industry and regulatory standards. Contract research organizations (CROs) also identify preferred clinical investigator sites and assist with site selection based on previous experience and performance. This upfront clinical development work performed by a CRO speeds up the start-up activities and timelines for a clinical trial program.
Clinical Operations Services
For clinical operations services, CROs handle all activities related to initiating, monitoring and closing out clinical trial sites. This includes providing site feasibility assessments, collecting signed investigator agreements and contracts, shipping study drug supplies, enrolling and collecting informed consent from subjects, conducting regular site monitoring visits, addressing compliance issues and collecting documentation for archiving. By taking on these routine clinical operations tasks, sponsors gain efficiency and site performance improves due to the expertise and dedicated resources applied by CRO personnel. CROs track site activities using purpose-built clinical trial management systems to provide sponsors with real-time visibility and reports on study progress.
Clinical Data Management Services
Ensuring accurate and timely collection, cleaning and reporting of clinical trial data is critical for success. CRO clinical data managers have deep experience in the development and validation of electronic data capture (EDC) systems, database designs, medical coding, query resolution and clinical study report preparation. Outsourcing clinical data management to an experienced CRO helps minimize data errors, consistently meet database lock timelines and gets sponsors access to professional data management oversight and expertise. CROs adhere to industry standard data management practices and are well-versed in regulatory expectations for data handling and records retention.
Biostatistics Services
For biostatistics analysis and reporting, CROs provide qualified biostatisticians, medical writers and programmers skilled in clinical trial data analysis and reporting. Along with designing the statistical analysis plan, CRO biometrics teams perform the interim, primary endpoint and final clinical study analyses and reporting required for regulatory filings. Rather than building biostatistics capabilities internally, sponsors gain immediate access to statistical analysis and reporting expertise through outsourcing to a CRO. CRO biostatisticians are highly skilled at identifying key efficacy and safety variables and performing analyses to industry and regulatory health authority standards for clinical trial design and end-point evaluation.
Medical Writing and Regulatory Consulting
With medical writing and regulatory consulting support, sponsors can outsource the development of clinical study reports, investigator brochures, regulatory documents like the clinical trial application or investigational new drug application, and safety reporting needed for FDA and global health authority submissions. Experienced medical writers at CROs understand formatting and content expectations for these critical documents based on health authority guidance. They work collaboratively with clients to ensure consistency across documents and include all requested analyses and clinical narrative components. CRO regulatory experts also provide strategic regulatory consultation to help sponsors design development programs that satisfy global authorities. By outsourcing medical writing and regulatory work to a CRO, sponsors avoid building internal capabilities that may only be utilized intermittently.
Benefits of Using a CRO
when sponsors choose a qualified CRO partner, they gain access to dedicated clinical research professionals, scalable resources and expertise spanning the entire clinical development lifecycle. This allows sponsors to focus internal resources on core competencies like product development, while relying on the CRO to perform clinical operations efficiently. With project management oversight and real-time study status updates provided by the CRO, clinical timelines can be met more consistently. By using pre-qualified CRO investigator sites, sponsors also reduce start-up time per site and ensure enrollment targets are reached smoothly. Overall outsourcing to a CRO offers clear advantages in terms of reduced costs, accelerated timelines and enhanced clinical data quality and integrity versus going it alone or using multiple providers piecemeal.
