Study Endpoints

Primary Endpoints

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
Self-administered by participants (or a designated caregiver) per the participants regular TPN/ line access schedule, through study completion (up to 12 months)

The proportion of participants who remain infection-free in the treatment groups will be compared, censoring participants who do not experience a CLABSI, but fail to complete the 12-month follow-up period of the study.

Secondary Endpoints

Incidence of AEs, SAEs, treatment-emergent adverse events (TEAEs)
Self-administered by participants (or a designated caregiver) per the participants regular TPN/ line access schedule, through study completion (up to 12 months)
Incidence of changes in laboratory evaluations, vital signs, or physical exam findings
Self-administered by participants (or a designated caregiver) per the participants regular TPN/ line access schedule, through study completion (up to 12 months)

Frequently asked questions about DefenCath

What is DefenCath used for?

DefenCath is a catheter lock solution being studied to reduce central line associated bloodstream infections, or CLABSIs, in adults and adolescents who receive total parenteral nutrition through a central venous catheter. It is an investigational product in Phase 3 development for this infectious disease indication.

Who makes DefenCath?

DefenCath is developed by CorMedix Inc., which trades on the Nasdaq under the ticker CRMD. The company is the sponsor of the clinical program evaluating the catheter lock solution in patients receiving total parenteral nutrition through a central venous catheter.

What phase is DefenCath in?

DefenCath is in Phase 3 clinical development. The program is investigating whether the catheter lock solution reduces central line associated bloodstream infections in adults and adolescents receiving total parenteral nutrition through a central venous catheter. It remains an investigational product and is not approved for this use.

What clinical trials is DefenCath in?

DefenCath is being evaluated in the Phase 3 trial NCT06822426, titled Comparing The Safety And Efficacy Of DEFENCATH In Reducing Central-Line Bloodstream Infections (CLABSIs) In Adults And Adolescent Participants Receiving Total Parenteral Nutrition Through A Central Venous Catheter (CVC). The trial is recruiting and plans to enroll 200 participants in the United States and Turkey.

Is DefenCath the same as a catheter lock solution?

Yes. DefenCath is also known as a taurolidine and heparin catheter lock solution, and is sometimes referred to simply as a catheter lock. These names describe the same product being developed by CorMedix for reducing central line associated bloodstream infections in patients receiving total parenteral nutrition through a central venous catheter.

What is the design of the DefenCath Phase 3 trial?

Trial NCT06822426 is a randomized, double-blind, active-controlled Phase 3 study of DefenCath in patients aged 12 years and older receiving total parenteral nutrition through a central venous catheter. It is recruiting 200 participants across the United States and Turkey, and healthy volunteers are not eligible.
