New NIDDK Specimen Access Program (Replaces X01 Mechanism)

Here is the information from the NIDDK Central Repository:

"NIDDK has launched a new Specimen Access Program (SAP) for requesting specimens from the NIDDK Central Repository. This process replaces the X01 Resource Access mechanism (PAR-22-171) and serves as the updated pathway for all specimen requests. The SAP provides a streamlined application and review process for investigators to request specimens from NIDDK-supported clinical studies. All requests undergo scientific merit review and stewardship evaluation to ensure responsible use of valuable repository resources based on funding status and specimen availability (depletion risk).

Review Pathways & Timelines

• Administrative Review: For requests with minimal impact on repository inventory; decisions typically within 2–4 weeks.
• Full Scientific Merit Review: For requests involving non-renewable or significantly depleting specimens; decisions typically within 6–8 weeks.

Timelines vary based on submission completeness. For Full Scientific Merit Review, applicants will receive decision letters outlining approval, conditional approval, requested revisions, or non-approval. Approved requests will include information on specimen quantities, release conditions, and next steps.
