NovaBay Pharmaceuticals Completes 34 Patient Phase 2B Clinical Study

NovaBay® Pharmaceuticals, Inc. (NYSE MKT: NBY), a biopharmaceutical company focusing on commercializing and developing non-antibiotic antimicrobial products for the global eye care market, announces plans to report results from a clinical study with its proprietary anti-microbial compound auriclosene (NVC-422) to reduce urinary catheter blockage and encrustation in patients with long-term indwelling urinary catheters in early December.

Due to spinal cord injuries, multiple sclerosis, strokes or other neurogenic bladder conditions, an estimated 100,000 patients in the U.S. have indwelling catheters and episodically suffer from blockage and encrustation. In these patients catheters repeatedly become coated with bacteria and bacterial biofilm, which may produce localized crystal deposits that may build up and block the catheter. The severe consequences of urinary catheter blockage and encrustation are often underappreciated. Catheter blockage can result in urinary tract infections, socially embarrassing urine leakage around the catheter, and frequent use of emergency services. In those with high-level spinal cord injuries, potentially life-threatening autonomic dysreflexia can occur.

“In September 2014 we initiated a two-arm, parallel-design study comparing Auriclosene Irrigation Solution (AIS) to its vehicle,” said NovaBay President and CEO Ron Najafi. “This followed positive results of an earlier Phase 2 cross-over design study for the treatment of urinary catheter blockage and encrustation in which AIS was compared to saline solution, the standard of care. However, early in 2015 we refocused NovaBay’s commercial strategy with the launch of our proprietary Avenova™ Daily Lid and Lash Hygiene product as our top priority with an eye toward monetizing other assets in our pipeline. We decided to move forward with the evaluation of data from the group of patients enrolled to date in this clinical trial as we believe that auriclosene has significant potential in this indication. The results, if positive, could improve the value at which we monetize this auriclosene asset.”

The study results will include data from 34 evaluable subjects with indwelling urinary catheters randomized into two equal arms. Subjects received irrigations of AIS or its vehicle administered two times a week for four weeks. The objectives of this study are to evaluate catheter flow rate reduction, early removal of catheters due to clinical blockage as well as safety and tolerability of AIS.

In September 2013 NovaBay announced highly statistically significant benefit of AIS compared with saline in the earlier Phase 2, double blind, randomized, cross-over designed study. In this study catheters of the subjects were irrigated twice weekly with a solution of either AIS or saline for a total of eight treatments over four weeks, followed by a washout period and a similar cross-over treatment. For the 14 subjects completing this study AIS significantly reduced encrustation and blockage (p<0.001). There were no cases of blockage in the AIS treated group whereas blockage occurred in the majority of the saline treated group. No significant safety or tolerability issues were identified.

About Auriclosene (NVC-422)
Auriclosene is NovaBay’s lead Aganocide compound. These compounds work by mimicking the body’s natural defense against infection. Since the body’s immune system works without ever creating resistance, NovaBay has taken the effective and rapidly acting molecules that function within our own bodies and created stable analogs of these molecules. The Company’s compounds have shown to be fast-acting with broad spectrum activity, effective against multi-drug resistant bacteria and biofilm, and with a good safety profile.

About Urinary Catheter Blockage and Encrustation
Blockage and encrustation of indwelling catheters results from the build-up of calcium and magnesium crystals in the lumen and inlet of catheters, which is caused by gram-negative bacteria. The condition requires catheters to be changed frequently. It can also lead to urinary tract infections, kidney infections and incontinence due to the leakage of urine around the outside of clogged catheters. In certain patients, severe and life-threatening episodes of uncontrolled autonomic dysreflexia can occur. Autonomic dysreflexia is an involuntary nervous system reaction to noxious stimuli that can lead to a sudden, severe increase in blood pressure. The most frequent causes of autonomic dysreflexia in those with an indwelling catheter are bladder over distention and catheter blockage. The autonomic dysreflexia continues until the blocked catheter is changed. If blockage is not dealt with immediately, the increased blood pressure could lead to a life-threatening stroke or cardiovascular event.
