Maintaining Enrollment Momentum and Data Quality in a Multinational Phase II Alzheimer’s Disease Study
How Strategic Site Engagement and Patient-Centric Retention Supported Study Success
A Phase II Alzheimer’s disease study evaluating an investigational therapy faced significant operational challenges, including a complex biomarker-driven design requiring repeated lumbar punctures over an 18-month treatment period. The demands of recruitment, retention, and participant compliance were further complicated by the onset of the COVID-19 pandemic, which disrupted site operations and patient access across multiple countries.
This case study demonstrates how a proactive operational strategy, combining strategic site selection, strong site engagement, patient-focused retention initiatives, and rigorous risk management, helped sustain enrollment momentum and support critical biomarker collection throughout the study. Despite pandemic-related disruptions, close collaboration among sponsors, sites, and service providers enabled consistent study execution, protocol compliance, and high-quality data delivery.
