A 4-week, prospective, randomized, clinical trial evaluating 45 patients with chronic wounds. All wounds received serial debridement and either BlastX Antimicrobial Wound Gel, custom topical antibiotics Standard of Care (SOC) or the combination of both.
‣ Wound Closure: 1.5X relative increase in wound treatment success over the SOC when using BlastX, (53% and 80% respectively, P<0.05), with no statistical difference over BlastX when BlastX and the SOC were combined.
‣ Wound Volume Reduction: 32% greater wound volume reduction when using BlastX compared to the SOC.
* A successfully treated wound is defined as >50% reduction of wound volume in 4 weeks. BlastX Antimicrobial Wound Gel works by creating a moist wound healing environment that removes barriers to the body’s natural healing process. Please refer to indications for use of this product.
BlastX Antimicrobial Wound Gel Demonstrates Successful Management of the Wound10
The Challenge of Chronic Wounds and BiofilmBiofilm is prevalent in nearly 80% of all chronic wounds and it perpetuates the inflammatory phase of wound healing.1
As biofilm matures, bacteria continue changing their phenotype, sharing their resistance to antibiotics with the community.2
Compounding this challenge is the fact that current available biofilm treatments can stall healing.12
The periodic release of planktonic bacteria from biofilms has been linked to chronic relapsing infections.5

BlastX Antimicrobial Wound Gel Reduces Biofilm Bacteria 4-6 Log in Laboratory Tests
In in vitro studies, BlastX Antimicrobial Wound Gel was compared to antimicrobial containing therapies. 24 hours after application, measurements were taken for two different kinds of biofilm bacteria (S. aureus and P. aeruginosa). Compared to the other topical antimicrobials, BlastX Antimicrobial Wound Gel significantly reduced the number of biofilm bacteria present by 4 to 6 log.8,9

Biofilm EPS MatrixNegatively Affects HealingBiofilms are formed in wounds when bacteria attach to surface structures and produce a protective barrier called extracellular polymeric substance (EPS). This biofilm matrix surrounds and encapsulates the bacteria, shielding them from both mechanical and chemical attack. EPS protects bacteria—making it up to 1000x more difficult to eradicate—and delays the wound healing process.3,4
Wound biofilms are comprised of EPS matrix and may containpolymicrobial species of: ‣ gram-positive bacteria ‣ gram-negative bacteria ‣ fungi and spores
FDA CLASSIFICATION: Federal law (USA) restricts this device to sale by or on the order of a licensed healthcare practitioner.
Discover the X Factor
BlastX is a breakthrough antimicrobial wound gel powered by Next Science’s patented, non-toxic, biofilm-disrupting Xbio™ Technology.
It deconstructs the bacterial biofilm EPS matrix, destroys bacteria within the gel, and defends from recolonization while maintaining a moist wound environment.

The 3 Dimensions of How BlastX Antimicrobial Wound Gel Works
DECONSTRUCTthe bacterial biofilm matrix
As opposed to free-floating bacteria, biofilms are powerful communities that function as a single entity with robust defense mechanisms. By targeting the biofilm structure and breaking it apart, Next Science’s Xbio Technology deconstructs the biofilm matrix without harming healthy human tissue.9
DESTROYbacteria within the Technology
With the biofilm matrix dissolved, bacteria are exposed and more vulnerable to attack. The Xbio Technology creates a high osmolarity condition. This environment coupled with a surfactant induces cell lysis for bacteria enveloped within the gel. Cell lysis is nondiscriminatory, therefore Xbio Technology destroys gram-positive and gram-negative bacteria, persister cells, and spores.9
DEFENDfrom recolonization
Disrupting and destroying the biofilm matrix can reduce the rate of recurrence more than 100x, effectively defending against recolonization. Other antimicrobial agents may claim to destroy biofilms; however their efficacy could be undermined by bacterial resistance. In contrast, the biofilm matrix cannot re-form in the presence of the BlastX Antimicrobial Wound Gel wound gel. There is no known evidence of bacterial resistance to the Xbio Technology.9
