Investigational Product, Dosage and Mode of Administration: 
 26-mL Applicator will be applied topically to the region of surgical incision using 
repeated back and forth strokes. For dry surgical sites such as the abdomen or arm, the product will be applied 
for a period of at least 30 seconds and for moist surgical sites (such as the inguinal fold) for 2 minutes. The 
application area should be allowed to air dry for approximately 3 minutes.  
Reference Therapy, Dosage and Mode of Administration: 
 will be applied according to the 
prescribing information. 
Duration of Study: Each patient will participate in the study for up to 51 days, including up to 21 days for 
screening  and 30-days of post-surgical follow-up for evidence of any SSI or other AEs. 
Criteria for Evaluation: 
Primary Efficacy Endpoint: The primary efficacy endpoint is the occurrence of any SSI within 30 days after 
surgery. A secondary analysis of the primary efficacy endpoint are subgroup analyses including: 
• 
Different types of SSI classified as superficial incisional infection, deep incisional infection, or organ-
space infection 
• 
Clean (class I wound) or clean-contaminated (class II wounds) surgeries 
Safety Endpoints: Safety endpoints will be analyzed over the entire treatment and follow-up period. 
• 
AEs (including local application site reactions and allergic reactions) 
Statistical Methods: 
Analysis Populations: The full analysis set includes all patients who were randomized to study treatment, 
received the study treatment, and underwent surgery. The per-protocol (PP) subset includes all full analysis set 
patients who had final follow-up at 30 days post-surgery. The safety subset will include all patients who were 
randomized to the study and received a study treatment and will be analyzed as they were treated. 
Statistical Analyses: All baseline data and efficacy and safety endpoints will be presented by descriptive 
statistics including numbers and percentages for categorical variables and mean, standard deviation (SD), 
median, minimum and maximum values for continuous variables. All data will be presented for all three of the 
analysis sets. 
AEs will be coded using the most recent version of the Medical Dictionary of Regulatory Activities (MedDRA) 
preferred terms and will be grouped by system, organ, and class (SOC) designation. The severity, frequency, 
and relationship of AEs to investigational products will be presented by preferred term by SOC grouping. 
Listings of each individual AE including start date, stop date, severity, relationship, outcome, and duration will 
be provided. Each AE (based on preferred terminology) will be counted once only for a given study patient. If 
the same AE occurred on multiple occasions, the highest severity and relationship to investigational product 
will be assumed. Thus, study participants are not counted multiple times in a given numerator in the calculation 
of frequencies for a specific AE. The frequency and severity of skin irritation or allergic reactions at least 
possibly attributed to each product will also be presented. The number and percentage of patients who were 
prescribed prophylactic antibiotics and antibiotics to treat an infection as well as patient’s adherence to the 
 standard preop surgical instructions, will also be summarized.

6.4. 
Investigational Product Accountability 
Zurex requires Investigators to maintain accountability and adequate inventory security of the 
study material at all times. The Investigator or designee will: 
• Complete a Confirmation of Release and Receipt of Study Materials form upon 
receipt of the shipment and maintain and account for inventory on the Study Material 
Disposition form  
• Keep study materials in a secure storage area, accessible only to authorized 
individuals. 
• Dispense study material only to patients properly enrolled into the study. 
• Return all unused study materials to Zurex Pharma, Inc. at the end of the study or 
dispose of unused study materials as agreed upon. 
7. 
Study Procedures 
7.1. 
Recruitment of Patients 
Patients anticipating undergoing clean (class I wound) or clean-contaminated surgery (class 2 
wound) will be identified during chart review. See Appendix A for a description of wound 
classifications. If the potential participant is planning one of these procedures and otherwise 
appears to be eligible (e.g., ≥ 18 years old, no medical exclusions from chart review), the PI or 
designee will explain the study to the patient and if the patient is interested he/she will go 
through the informed consent procedure.  
7.2. 
Eligibility Screening 
Preliminary eligibility for study participation will be assessed as described above. If the patient 
appears to be an appropriate candidate for the study, a member of the study staff trained in 
human subjects’ protections will perform the informed consent process by explaining the nature 
and scope of the study and the potential risks and benefits of participation. The study will be 
explained to the potential subject in lay terms and in a quiet, private setting. Potential subjects 
will be given as much time and privacy as necessary to review the informed consent and ask any

stratified permuted block randomization procedure will be performed via an interactive web-
based randomization system (IWRS) with type of surgery [clean (class I wound) or clean-
contaminated (class II wounds) surgery]) as the stratification variable. 
If the patient is randomized and is never treated with one of the investigational products or never 
underwent surgery, then the patient will be considered a randomization failure and an additional 
patient will be randomized with the next randomization sequence at the time he/she is 
randomized. The reason(s) that a patient was considered a randomization failure or screen failure 
will be documented in source documents and eCRFs. 
7.4.2. 
Preoperative Surgical Instructions 
Each patient undergoing surgery at the MCW is instructed to shower with an antiseptic agent 
before the day of surgery. Additionally, the surgical staff follows standard preoperative surgical 
orders while prepping the patient for surgery. The patient will be asked about adherence to the 
instructions before surgery and the source documents will be checked for adherence to the 
standard preoperative surgical orders / activities the day of surgery.    
7.5. 
Interventions (Day 1) 
Patients will have the region surrounding the surgical site scrubbed with the assigned product as 
described in section 6.3. 
7.6. 
Assessments During the Inpatient Period 
During the post-surgical period while the patient is still in the hospital, the surgical site and 
surrounding area will be examined for signs of infection or other deep incisional infection and if 
evident, this will be recorded. Local skin reactions (erythema, rash, or pruritus) or other systemic 
allergic reactions to the investigational product will be recorded. Other AEs will be assessed by 
asking the patient an open ended question: How are you feeling? If any antibiotics are prescribed 
for prophylaxis or treatment of an AE, these will be reported. On the day of hospital discharge, 
all of the above assessments will also be performed. The patient will be given standard discharge 
instructions and a card with the name of study nurse or doctor to contact in the event of any post-
surgical complications. Patients will be scheduled for an examination appointment or possibly to 
come to the emergency room if any possibly serious complications have occurred.  
7.7. 
Assessments During the Outpatient Period 
If an outpatient follow-up visit has been scheduled, a physical examination should be performed 
including inspection of the surgical site for signs of an SSI and the skin at the application site for 
signs of an allergic reaction and new antibiotic prescriptions. Other AEs should be assessed with 
an open ended question and data will be recorded.  
7.8. 
Telephone Assessments 
Three-to-five days after hospital release, on study Day 30 or at any time a patient calls with a 
complaint, a telephone scripted interview will be completed that assesses AEs and the patient 
should be queried if they had any other doctor’s office visits that might be indicative of a post-
surgical problem indicative of an SSI or AE. If the patient cannot be contacted at Day 30, a 
person that they listed on the locator form should be called to determine if the patient died or is

deep incisional infection (which involves fascia and muscle), or organ-space infection 
(which involves any organ or space other than the incised layer of body wall that was 
opened or manipulated during the operation) (definitions in accordance with CDC-
2019 will be used). 
• SSI rates by type of surgery including clean (class I wound) or clean-contaminated 
(class II wounds) surgeries 
8.2. 
Safety Endpoints 
Safety endpoints will be analyzed over the entire treatment and follow-up period. 
• AEs (including specifically local application site reactions and allergic reactions) 
9. 
Safety Monitoring Plan 
Safety monitoring will be conducted throughout the study; therefore safety concerns will be 
identified by continuous review of the data by the PI, clinic staff, clinical monitor, medical 
monitor, and Zurex. 
The IRB, Medical Monitor, PI, Clinical Monitors and Zurex will review any safety concerns 
throughout the trial. The roles of these individuals are described below. 
Medical Monitor: A Medical Monitor has been appointed for the study. The Medical Monitor 
will be available for making recommendations to the investigator and Zurex on the severity of 
any SAEs, and the relatedness to the study interventions. The Medical Monitor will also be 
responsible for tracking and assessing trends in the AEs reported. 
Clinical Monitors: The PI will allow representatives of Zurex to periodically monitor, at 
mutually convenient times during and after the study, all study data. These monitoring visits 
provide Zurex with the opportunity to evaluate the progress of the study and to obtain 
information about potential problems. The monitors will assure that submitted data are accurate 
and in agreement with any medical records or paper source documentation used; verify that 
investigational products are properly stored and accounted for, verify that patients’ consent for 
study participation has been properly obtained and documented, confirm that research subjects 
entered into the study meet inclusion and exclusion criteria, and assure that all essential 
documentation required by Good Clinical Practices (GCP) guidelines are appropriately filed. 
Monitors will conduct a site initiation visit prior to the start of the study. At this visit, they will 
assure that proper study-related documentation exists, assist in training investigators and other 
site personnel in study procedures and GCP guidelines, confirm receipt of study supplies, and 
assure that acceptable facilities are available to conduct the study. 
Routine monitoring visits by Zurex’s representatives will be scheduled at appropriate intervals 
but more frequently at the beginning of the study. At these visits, the monitors will verify that 
study procedures are being conducted according to the protocol guidelines, monitor eCRFs 
against source documents, review AEs and SAEs, and perform drug accountability. At the end of 
the study, they will confirm that the site has the appropriate essential documents on file, advise 
on storage of study records, and inspect the return and destruction records for unused 
investigational products.

Assessment Methods 
All study assessments will be performed at the time points outlined in the Schedule of 
Assessments (Table 3) that is somewhat flexible due to different lengths of hospitalization after 
surgery and depending on the needs of the patient. The following sections outline the details and 
procedures associated with the assessments. All specified assessments will be recorded on a 
source document or the medical record and appropriate data will be transcribed into electronic 
case report forms (eCRFs). 
10.1. 
Adverse Events and Serious Adverse Events 
The investigator and study site staff are responsible for the detection, documentation, 
classification, reporting, and follow up of events meeting the definition of an AE or SAE. 
10.1.1. 
Adverse Event Definition 
An AE is any untoward medical occurrence in a patient or clinical investigation subject 
administered a pharmaceutical product and may not necessarily have a causal relationship with 
the administered treatment. An AE can therefore be any unfavorable and unintended sign 
(including a clinically significant laboratory abnormality), symptom, or disease temporally 
associated with the use of an investigational product, whether or not related to the investigational 
product. Pre-existing conditions, diseases, or disorders are not considered AEs unless there is a 
change in severity or frequency. Planned surgeries will not be considered an AE. 
10.1.2. 
Serious Adverse Events and Serious Unexpected Adverse Events Definition 
An SAE is any untoward medical occurrence that meets one of the following: 
• Results in death 
• Is life-threatening (at the time of the event) 
• Requires inpatient hospitalization or prolongation of existing hospitalization 
• Results in persistent or significant disability/incapacity 
• Is a congenital anomaly/birth defect 
A serious and unexpected AE is an SAE that is not identified in nature, intensity, or frequency in 
the risk information included in the Product Label for the drug. 
Important medical events that may not result in death, be life-threatening, or require 
hospitalization may be considered a serious adverse drug experience when, based upon 
appropriate medical judgment, they may jeopardize the study patient and may require medical or 
surgical intervention to prevent one of the outcomes listed in the definition. 
10.1.3. 
Methods/Timing for Assessing, Recording, and Analyzing Safety Endpoints 
AEs will be assessed starting after the first administration of investigational product until the 
final follow-up at Day 30. General symptoms will be collected via an open ended question: How 
have you been feeling since the last time we spoke? Elicited AEs will be assessed as described in 
section 10.1.4.

Confidential 
 
AEs will be documented in the medical/source records, and recorded on the eCRF using 
accepted medical terms and/or the diagnoses that accurately characterize the event. When a 
diagnosis is known, the AE term recorded on the eCRF will be the diagnosis rather than a 
constellation of symptoms. The investigator will assess all AEs for seriousness, relationship to 
investigational product, and severity. When an event has not resolved by study closure, it will be 
documented on the AE CRF as “ongoing”. 
All AEs, including clinically significant abnormal findings on laboratory evaluations, regardless 
of severity, will be followed by study physicians until satisfactory resolution (the event either 
resolved or stabilized and is not expected to resolve in the near term). At the follow-up telephone 
contact, AEs will be recorded and followed to resolution only if they are serious, or if the study 
physician assesses them to be clinically significant. 
10.1.4. 
Elicited Adverse Events 
In addition to asked the open ended question regarding AEs, local application site reactions will 
be assessed by physical examination or querying the patient. These include the appearance of 
erythema or rash, or patient reported pruritus (itching). 
10.1.5. 
Classification of Adverse Event Severity and Relationship to Investigational 
Product 
For each recorded AE or SAE, a physician-investigator must make an assessment of severity 
according to the following criteria: 
Mild: 
An event that is usually transient, requiring no special treatment, and does 
not generally interfere with the patient’s daily activities. 
Moderate: 
An event that interferes with usual activities of daily living, causing 
discomfort but poses no significant or permanent risk of harm to the 
patient. The event is usually ameliorated with additional specific 
therapeutic intervention. 
Severe: 
An event that interrupts usual activities of daily living or significantly 
affects clinical status. The event poses a significant risk of harm to the 
patient and hospitalization (prolonged) may be required, and typically 
requires intensive therapeutic intervention. 
Life-
threatening 
An event that puts the patient into imminent risk of death without 
intervention. 
The severity of application site reactions will be scored as shown in Table 4.

The investigator must make an assessment of relationship of the AE to the investigational 
product based on the following criteria: 
Unrelated: 
The patient did not receive the investigational product, the temporal 
sequence of the AE/SAE onset relative to administration of the 
investigational product is not reasonable, or there is another obvious cause of 
the AE/SAE. 
Unlikely: 
There is evidence of exposure to the investigational product but there is 
another more likely cause of the AE/SAE. 
Possible: 
There is evidence of exposure to the investigational product, the temporal 
sequence of the AE/SAE onset relative to administration of the 
investigational product is reasonable, but the AE/SAE could have been due 
to another equally likely cause. 
Probable: 
There is evidence of exposure to the investigational product, the temporal 
sequence of the AE/SAE onset relative to administration of the 
investigational product is reasonable, and the AE/SAE is more likely 
explained by the investigational product than by any other cause. 
Definite 
There is evidence of exposure to the investigational product, the temporal 
sequence of the AE/SAE onset relative to administration of the 
investigational product is reasonable, the AE/SAE is more likely explained 
by the investigational product than by any other cause, and the AE/SAE 
shows a pattern consistent with previous knowledge of the investigational 
product or investigational product class. 
10.1.6. 
Outcomes and Actions Taken 
For each recorded AE or SAE, the investigator must make an assessment of outcome at the time 
of last observation, as follows: 
Fatal: 
The patient died. 
Resolved without Sequelae: 
The AE or SAE has ended.

Resolved with Sequelae: 
The AE or SAE has ended but changes are noted 
from baseline. 
Unresolved – Ongoing: 
The AE has not ended and is ongoing at the end of the 
reporting period or the investigator deems that further 
follow up is not medically required 
Unknown – Lost to Follow-up: 
Lost to follow-up at least 2 repeated, documented (15 
days apart) unsuccessful attempts to contact the 
patient. 
 
In addition, if the AE was treated (medications or other physical measures), this will also be 
recorded. 
10.1.7. 
Reporting Serious Adverse Events 
10.1.7.1. 24-hour Reporting Requirements (Initial Report) 
Any SAE, including death due to any cause, which occurs to any patient from the time of signing 
consent through the final follow-up telephone call whether or not related to the investigational 
product, must be reported within 24 hours of knowledge of the event by completing the AE/SAE 
eCRF. This will trigger an automatic notification of the SAE via an email communication to 
Zurex and 
. 
will notify the Medical Monitor upon receipt of the 
notification and coordinate communications with the Medical Monitor. 
10.1.7.2. 3-Day Supporting Documentation Requirements 
Written documentation for all SAEs must be received by  Zurex and 
 within 3 
business days of reporting the event. Required eCRFs that must be completed include the 
following: 
• AE/SAE eCRF (revised if additional information is available) 
In addition, scanned copies of the following may be requested to be uploaded to the data 
management system. 
• Copies of medical records/source documents pertinent to the event (laboratory 
reports, ECG tracings, medical chart notes, etc.). These should be identified only by 
Patient number and not include any patient identification information prohibited by 
Health Insurance Portability Accountability Act (HIPAA). 
• Any other relevant information necessary to support the investigator’s judgment 
regarding the SAE’s relatedness severity to the investigational product OR by request 
of the Medical Monitor/Alternate. 
These paper documents may be submitted by facsimile, as email attachments, or by attaching 
them to the patient’s eCRF casebook in the electronic data management system (EDMS).

Eligibility Checklist 
An Eligibility Checklist which includes all inclusion and exclusion criteria will be reviewed in 
after screening measures are completed and on the day of surgery prior to randomization on 
Study Day 1. If the patient is not eligible for the study, the reasons for ineligibility will be 
recorded on an eCRF. These patients will be considered screen failures. 
10.4. 
Locator Form 
After signing informed consent, patients will be asked to provide names, addresses, and phone 
numbers of several friends and/or family members who can be contacted if the patient cannot be 
located (Locator Form). This locator form will be used to assist in contacting patients after 
hospital discharge and at the final follow-up. This form asks patients his/her name, address, and 
phone number and to provide names, addresses, and phone numbers of several friends and family 
members who can be contacted if the patient cannot be located. This information is essential and 
will be collected during screening, and will be updated on the day of hospital discharge, if 
needed. This information will remain exclusively at the site.  
10.5. 
Medical History 
Medical history will be reviewed during screening to determine patient eligibility and also to 
record any past or current medical conditions including the reason for the planned surgery and 
the type of surgery that is anticipated. Any allergies to medications including 
, 
isopropyl alcohol, or other excipients in 
 Solution will also be recorded. 
Medical history findings will be reported on an eCRF. Childbearing potential in females and if 
currently breastfeeding will be recorded. Females of childbearing potential will have a pregnancy 
test. Pregnant or breastfeeding females will be excluded from the study. 
10.6. 
Medications 
Antibiotics taken up to 4 days prior to surgery or throughout the study until Day 30 will be 
recorded including the indication (i.e., prophylaxis or to treat an AE), start and stop dates, dose, 
route and frequency and will be reported on an eCRF. 
10.7. 
Physical Examination  
An appropriate pre-surgical physical examination will be conducted as part of screening and any 
relevant findings will be recorded. Post-surgical physical examinations will include signs of 
surgical site or other infection and other AEs such as local application site reactions (erythema, 
or rash). These data will be recorded on a medical record and an eCRF. 
10.8. 
SSI Diagnosis 
A study physician will evaluate the patient and medical records for evidence of SSI up to Day 
30. A determination of the type of SSI (Superficial Incisional SSI, Deep Incisional SSI, and 
Organ/Space SSI) will be made in accordance with CDC criteria as summarized in Appendix B.

Adverse Events 
AEs will be coded using the most recent version of the Medical Dictionary of Regulatory 
Activities (MedDRA) preferred terms and will be grouped by system, organ, and class (SOC) 
designation by treatment group. The severity, frequency, and relationship of AEs to 
investigational products will be presented by preferred term by SOC grouping. Listings of each 
individual AE including start date, stop date, severity, relationship, outcome, and duration will be 
provided. Each AE (based on preferred terminology) will be counted once only for a given study 
patient. If the same AE occurred on multiple occasions, the highest severity and relationship to 
investigational product will be assumed. Thus, study participants are not counted multiple times 
in a given numerator in the calculation of frequencies for a specific AE. The frequency and 
severity of skin irritation or allergic reactions at least possibly attributed to each product will also 
be presented.
