Brief Summary

The primary study objective is to evaluate the benefit of the Sirolimus eluting Collagen implant (SeCI; Sirogen), a single dose prophylactic treatment delivered intraoperatively at the time of surgical creation of an arteriovenous fistula for hemodialysis vascular access.

Detailed Description

This is a Phase 3, multicenter, randomized, single-blind, controlled, study designed to evaluate the efficacy and safety of the use of the Sirolimus-eluting Collagen Implant (SeCI) in subjects who are on hemodialysis and are undergoing surgical creation of an AV fistula in comparison to subjects who do not receive the implant.

Subjects of either gender, who are at least 65 years of age, undergoing hemodialysis, and require a new single stage radiocephalic end to side fistula will be eligible to participate in this study. Subjects who meet eligibility criteria and undergo successful AV fistula creation will be eligible for enrollment. The study plans to enroll approximately 120 subjects, randomized in a 1:1 ratio. Enrolled subjects will be followed for a period of one year from the time of their index surgical procedure.

Primary Outcome Measures
NameTimeMethod
Clinical Fistula Maturation (FM)6 Months

Clinical Fistula Maturation (FM) is defined as a fistula that can be cannulated with 2-needles for at least 75% of the dialysis sessions, including 3 consecutive sessions with a mean Qb of 300 mL/min (unless the prescribed Qb is \<300 mL/min) performed during any continuous 30 day period that commences no later than 180 days after randomization.

The primary endpoint will be summarized as a time-to-event endpoint for the SeCI (Sirogen) and control groups by reporting the cumulative proportion of AVF that achieve FM over time \[defined as the interval from access placement to the first session that the fistula can be cannulated with 2 needles (contributing to the FM definition)\].
