Gastrointestinal CRO Services for Complex Clinical Trials
Advance gastrointestinal clinical trials with an integrated CRO and eClinical technology partner built for endpoint sensitivity, operational clarity, and efficient execution across complex GI programs.
Sitero supports sponsors across inflammatory bowel disease, irritable bowel syndrome, NASH/MASH, GERD, celiac disease, hepatology programs, and rare GI disorders with full-service clinical trial delivery and integrated technology.
Gastrointestinal studies require close coordination across symptom-based endpoints, biomarkers, endoscopy, imaging, procedure-based visits, and patient retention. Sitero helps reduce fragmentation across sites, vendors, and study workflows.

Built for Gastrointestinal Trial Complexity
Gastrointestinal trials require consistent endpoint execution, specialized site workflows, thoughtful patient support, and clear coordination across operational and data functions. Sitero helps sponsors manage that complexity with coordinated services and connected technology.
Common gastrointestinal trial challenges include:
Clinical Trial Technology that Supports Execution
Sitero’s delivery model is supported by a broad eClinical ecosystem, including:
Mentor EDC
Integration advantage
EDC updates stay aligned with operations and data management, maintaining consistency across protocol changes, visit schedules, and endpoint workflow
Mentor RTSM
Integration advantage
RTSM and EDC integration reduces handoff risk across eligibility, treatment assignment, stratification (e.g., prior biologic exposure, disease severity), and visit workflows.
Mentor Site and Participant Payments
Integration advantage
Connected payment workflows can reduce site burden and improve sponsor visibility into payment status.
Mentor eConsent
Integration advantage
Real-time consent tracking enables faster response to version updates, procedural requirements, and re-consent needs.
Mentor CTMS and eTMF
Integration advantage
Connected workflows allow sponsors to track site readiness, training, activation timelines, and inspection readiness in one system.
Mentor Insights and Reporting
Integration advantage
Centralized reporting helps teams identify PRO compliance gaps, enrollment trends, procedure risks, visit deviations, and site performance earlier to support faster decisions.
