How Diligent supports Quality Management in clinical trials

Proper selection, management and oversight of GCP/GCLP service providers is critical for safety and compliance in clinical trials, so it’s vital to research all vendors fully and assess the risks of working with them.

Here’s how the Diligent Platform supports Quality Assurance in clinical trials, helping you to comply with GCP and global regulatory requirements.

Using the Diligent Qualification Platform, clinical trial sponsors have:

  • Rapid access to details of service providers’ capabilities and resources through answers to RFI (Request for Information) questions focused on our Qualification Standards.
    We currently have over 465 completed RFI questionnaires available for over 1100 service providers ready for you to use.
    These RFIs are based on a set of 29 industry agreed standards, developed and kept up to date by a consortium of 225+ trial sponsors and service providers.
  • A standardized approach to Vendor Qualification Assessment (VQAs) using the same industry-leading standards and a global network of experienced quality auditors.
  • A unique online comparison tool to evaluate up to 3 RFIs side by side.
  • The ability to request detailed RFI information for new providers – we approach service providers on your behalf, issue RFI questions, chase progress and review responses.
  • The ability to participate in VQAs already scheduled saving time and money.
  • The ability to request vendor qualification assessments for new service providers with whom your team is interested.
  • The ability to purchase anonymized reports from existing VQAs in the Diligent VQA library, saving even more time.
  • RFI and VQA Scoring Premium Service – We can serve as an extension of your staff by qualitatively evaluating providers against our qualification standards for your teams by evaluating VQA reports or RFI answers to “score” the relative risk areas of importance for your company. Our Scoring Premium Service can help you focus your attention on the highest areas of risk as you build your vendor risk management plans.
  • A dedicated Account Manager to ensure we meet your needs.

Outsourcing vendor qualification to Diligent reduces variability and enables improved compliance.
