KHI Current Project

Clinical Trial Endpoints for Dialysis Vascular Access

Patient Care Issue:

Hemodialysis vascular access has been called the “lifeline” for patients on hemodialysis. Unfortunately, due to the many problems associated with dialysis vascular access (stenosis, thrombosis, infection), it is also the “Achilles Heel” of hemodialysis. Specifically, more than 50% of arteriovenous fistulae (AVF) are unsuitable for hemodialysis four to five months following creation; the primary patency of arteriovenous grafts (AVG) has been reported to be as low as 23% at one year; and only 9% of tunneled dialysis catheters (TDCs) are still functional at one year.


An important barrier to the development of safe and effective therapies could be the lack of consensus as to the "right" clinical trial endpoints for this condition.

KHI Solution:

This project convenes the diverse stakeholders in this area (health professionals, industry, dialysis organizations, and federal agencies) to clarify appropriate trial endpoints for vascular access trials best suited to inform clinical, regulatory, and coverage decisions, in those circumstances where clinical data is required to support the decisions.


The workgroup’s three content development teams drafted the project’s white papers. The co-chairs are finalizing the definitions that will be used across the three papers. A final template for the white papers needs to be determined before the draft content can be update and prepared for submission.


Three parallel white papers on catheters, fistulas, and grafts endpoints.
