Post-Marketing Studies And Real-World Evidence Clinical Trials
Your trusted partner for decentralized post-marketing surveillance clinical trials and real-world evidence collection. Point-of-need accessibility. Proven compliance.

Traditional fixed-location sites face persistent challenges in post-marketing surveillance and post-approval studies. Limited patient access slows real-world data capture, while travel burden and scheduling constraints reduce retention and compromise patient safety monitoring. High operational costs and limited flexibility also make it difficult to generate evidence-based insights across diverse populations, which regulatory bodies such as the U.S. Food and Drug Administration (FDA) increasingly expect for ongoing safety studies.

Low Patient Compliance Patients often skip follow-up visits due to travel inconvenience, reducing adherence, study consistency, and overall long-term data reliability. |
Limited Real-World Data Restricted geographic reach limits diverse population representation, weakening study validity, generalizability, and real-world insight into treatment response, side effects, and product safety. |
High Dropout Rates Traditional trials experience 30–40% dropout in long-term studies, reducing statistical power, delaying timelines, and putting post-marketing commitments for new drugs at risk. |
Delayed Data Collection |
Why Choose 20/20 Onsite for Post-Marketing Surveillance Clinical Trials?
Post-marketing surveillance clinical trials are essential for monitoring drug safety and efficacy after FDA approval. At 20/20 Onsite, we revolutionize traditional post-marketing studies by bringing comprehensive ophthalmic assessments directly to patients' preferred locations, eliminating barriers that typically reduce participation and data quality in real-world evidence studies.

Implementation & Data Collection
Post-Marketing Surveillance with Multi-Site Execution and Real-World Data Capture
During the implementation phase, post-market clinical research requires efficient data collection across diverse patient populations in real-world settings, yet many studies struggle with traditional site limitations and fragmented data collection approaches.
Traditional collection methods often rely on fixed-site approaches that miss key patient segments, particularly when real-world evidence studies require specialized populations or point-of-care surveillance capabilities.
How Our Clinical Research Support Services Help?
20/20 Onsite executes comprehensive multi-site clinical trial post-marketing studies that combine community outreach, physician networks, and digital pharmacovigilance studies platforms for maximum real-world data collection efficiency.
Our post-marketing surveillance clinical trials team coordinates point-of-care surveillance and flexible assessment scheduling, bringing decentralized post-marketing surveillance directly to participants through mobile capabilities and community partnerships.
Data Reporting
Post-Marketing Surveillance with Comprehensive Regulatory Reporting
Maintaining data integrity and regulatory compliance throughout post-marketing surveillance clinical trials is critical for safety monitoring and regulatory requirements, yet data reporting challenges remain significant across all real-world evidence studies.
Traditional approaches often fail to address the complex data integration and safety signal detection requirements that are essential for effective pharmacovigilance studies and post-approval clinical studies.
