“The completed RFIs, the follow up with the vendor on our behalf, and the audit reports available, translate into time savings. I don't have to spend time following up with the vendor. I don't have to worry about getting a complete response and reviewing it entirely myself... We see a benefit that we get from our partnership with Diligent, enabling us to conduct more efficient and time-saving qualifications.”

About Regeneron

Regeneron Pharmaceuticals is a leading global biotechnology company that invents, develops, and commercializes medicines for serious diseases. 


The Challenge

Regeneron faced resource constraints managing their vendor qualification process. The manual, questionnaire-based approach required heavy involvement from in-house subject matter experts who needed to focus on core quality responsibilities rather than vendor qualifications. 

Managing multiple qualifications simultaneously with a small team on tight timelines became increasingly difficult. Preparing and reviewing RFI questionnaires consumed extensive time, and emailing vendors for follow-ups created bottlenecks that delayed approvals. The process was not scalable and created a growing audit backlog. 


The Solution: Diligent Pharma

Regeneron partnered with Diligent Pharma to transform their qualification approach. 

  • Pre-Completed RFIs: Regeneron accessed Diligent's global vendor database with completed qualification questionnaires, eliminating questionnaire preparation and the need to start from scratch each time. 

  • Expert Risk Analysis: Diligent SMEs conducted comprehensive risk scoring and quality verification for each vendor, providing accurate risk characterization while identifying potential risks specific to Regeneron's studies. 

  • Accelerated Timeline: Risk-based RFI evaluations enabled their team to approve vendors in days instead of weeks. 


The Results

“There are hundreds of completed RFIs in the diligent database... I grab them and save the time and effort to get those questionnaires completed by the vendor. And that cuts down 2 to 3 weeks from the qualification timeline.” 

Regeneron achieved: 

  • Hundreds of SME hours saved annually by shifting qualification burden to Diligent's platform and experts 

  • 20+ audits removed from backlog, freeing their quality team for higher-priority activities 

  • 2-3 week reduction in qualification timelines, completing evaluations in days instead of weeks 

  • 84%+ ROI through resource savings and improved efficiency 

  • Scalable qualification process without straining quality team resources
