Contract Research Organizations
Contract research organizations provide outsourced scientific, operational and data services for clinical development while sponsors retain responsibilities defined by law and contract.
Definition
Contract Research Organizations are companies supporting pharmaceutical, biotechnology and medical-device sponsors with trial design, site management, monitoring, data, statistics, safety and regulatory services.
Overview
CRO scope ranges from a single function to global full-service programmes. Sponsor oversight remains essential even when duties are transferred. Evaluation should examine therapeutic expertise, country and site capabilities, staff continuity, quality systems, data integrity, technology, subcontractors and inspection history.
Category scope
Portfolio and development focus
Development phase, therapeutic area, geographies, service scope, study design and sponsor model.
Development and operating model
Protocol support, sites, monitoring, data, statistics, pharmacovigilance, submissions and vendors.
Evidence, safety and supply risk
Protocol deviation, enrollment, staff turnover, data quality, safety reporting, vendors and inspection.
Typical lifecycle
- Discovery: identify biological rationale, candidate, indication and translational evidence.
- Preclinical development: study activity, safety, formulation, manufacturing and trial readiness.
- Clinical development: test safety and efficacy through ethically governed human studies.
- Regulatory and manufacturing: seek authorization and establish controlled, reproducible supply.
- Post-market stewardship: monitor safety, effectiveness, quality, access and required changes.
