About this trial
This is a Phase 3, randomized, double-blind, controlled, adaptive, 2-arm, multicenter study to demonstrate the efficacy and safety of DefenCath in adult participants receiving home Total Parenteral Nutrition (TPN) via Central Venous Catheter (CVC) compared with heparin.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Participants who are resident within the US and Türkiye.
Participants who are male or female, aged ≥18 years at the time of consent.
Participants must sign and provide informed consent.
Participants who have a permanent tunneled CVC or permanent peripherally inserted central catheter (PICC) made of silicone or polyurethane, which has been in place for at least 7 days prior to enrollment.
Disqualifiers
Any participant unable or not willing to sign inform consent.
Any participant who has received systemic antibiotic within the last 14 days. Topical antibiotics are permitted. Use of metronidazole or rifaximin for treating small intestinal bacterial overgrowth (SIBO) is also permitted.

Trial outcomes
Primary outcomes
Comparison between treatment groups of proportion of participants who experience a Central Line-Associated Bloodstream Infections (CLABSI) within 12 months of the start of the study
The proportion of participants who remain infection-free in the treatment groups will be compared, censoring participants who do not experience a CLABSI within 9 months, but fail to complete the 12 month follow-up period of the study.
Secondary outcomes
Incidence of AEs, SAEs, treatment-emergent adverse events (TEAEs)
Compare the safety profile of DefenCath for use as a Catheter Lock Solution (CLS) in adult participants receiving Total Parenteral Nutrition (TPN) through a Central Venous Catheter (CVC) to the control of heparin CLS
Incidence of changes in laboratory evaluations, vital signs, or physical exam findings
Compare the safety profile of DefenCath for use as a CLS in adult participants receiving TPN through a CVC to the control of heparin CLS
