This is a sources sought notice for market research, not a solicitation, aimed at determining the availability of qualified sources for a potential NIDA requirement. NIDA seeks vendors capable of serving as a data, statistics, and clinical trial service center for approximately 20 independent trials in drug use and addiction research, including data management, statistical analysis, document management, and clinical trial services. The work would support NIDA’s Clinical Trials Network by establishing secure web-based data systems, assisting in trial design and analysis, monitoring data quality and performance, coordinating Data and Safety Monitoring Board meetings, and participating in relevant committees. The government will evaluate responses based on demonstrated work experience, organizational experience, personnel qualifications, and facilities, with the NAICS code 541715 and a size standard of 1,000 employees or fewer applicable. No budget amounts or performance location are specified in this notice.
