Study to Evaluate NVC-422 for Urinary Catheter Blockage and Encrustation
Study to Evaluate NVC-422 for Urinary Catheter Blockage and Encrustation
NVC-422 is a topical, non-antibiotic, fast-acting, broad-spectrum anti-microbial, which
 exhibits the potential to prevent the growth of urinary pathogens, including Proteus and
 others.

 The use of a catheter irrigation solution that can prevent biofilm formation and encrustation
 leading to blockage may keep the catheter patent longer, resulting in fewer catheter changes,
 potentially lower incidence of UTIs, and better patient quality of life.

 The study population will include male and female spinal cord injury (SCI) and other
 neurogenic bladder patients with chronic indwelling transurethral urinary catheters who have
 a recent repeated history of urinary catheter encrustation and/or blockage.

 Subjects will receive two treatment regimens: one treatment regimen with NVC-422 sterile
 irrigation solution and one treatment regimen with sterile saline irrigation solution. Each
 treatment regimen will consist of a total of 8 treatments, with a washout period between
 treatment regimens.
Inclusion Criteria:

 -  Spinal Cord Injury (SCI) or other neurogenic bladder patient requiring a chronic
 indwelling urinary catheter with history of catheter blockage and/or encrustation

 -  Screening within 30 days of first treatment

 Exclusion Criteria:

 -  Systemic antibiotics within 7 days of first treatment

 -  Investigational drug or device within 30 days of enrollment

 -  Current infection that requires treatment with systemic antibiotics

 -  Recent history of significant autonomic dysreflexia (requiring intervention or
 treatment)
