Protocol Title: 
Preoperative Skin Preparation Study Following ASTM E1173 Methods to Evaluate the 
Antimicrobial Capabilities of Four Test Substances 
Planned Sample Size: 
This evaluation will be performed with an estimated of a minimum of 50 evaluable 
sites per product with qualifying treatment day microbial baseline counts. 
Overall Study Design 
and Plan: 
This study is designed to determine the antimicrobial effectiveness of three treatments 
(A, B and C), intended for use as Patient Preoperative Skin Preparation.  The testing 
methods are based on the standardized test method ASTM E1173-15, Evaluation of 
Preoperative, Precatheterization, or Preinjection Skin Preparations, and using the 
requirements specified by in the 2017 FDA 21 CFR Part 310, Safety and Effectiveness 
of Health Care Antiseptics; Topical Antimicrobial Drug Products for Over-the-Counter 
Human Use, Final Rule (December 20, 2017).  The immediate antimicrobial efficacy 
will be evaluated in this study. 
At least 100 subjects will be treated bilaterally with two of the four test materials (A, 
B, C and Positive Control), one per each side of the groin test site. Subjects will 
undergo at least a 14-day washout period before Treatment Day. During Treatment 
Day subjects who meet the Inclusion Criteria will be treated with the study products 
and samples will be taken before and after treatment application. The cup scrub 
technique will be used for sampling baseline, 30-seconds and 10-minutes on the 
Treatment Day. 
The immediate antimicrobial efficacy at 30 seconds and 10 minutes post-application 
will be demonstrated if the non-inferiority of the ATE of the investigational products 
(A, B and C) compared to Positive Control (D) is met (the upper two-sided 95% 
confidence bound of the post-application microbial counts corrected for Baseline of 
the investigational products  A, B or C compared to the Positive Control should be less 
than 0.5 log10). 
Study Methodology: 
ASTM Standard Test Method E1173-15 
Study Population: 
Healthy subjects at least 18 years of age and of any race. 
Treatment Day Baseline microbial count requirements are in the range of 5.00 to 
7.50 log10 CFU/cm2, inclusive, on the groin. 
Objectives: 
Efficacy objectives 
The objective of this study is to demonstrate immediate (30 seconds and 10 
minutes) antimicrobial efficacy of three investigational products (26 ml Project X, 
10.5 ml Project X and 5.1 ml Project X) compared to Prevantics® Maxi Swabstick 
5.1 ml (active control) on the groin. 
To demonstrate the immediate antimicrobial efficacy at 30 seconds and 10 minutes 
post-application the following criteria should be met on the groin: 
- 
non-inferiority of the ATE of the product A, B and C compared to product D 
(the upper two-sided 95% confidence bound of the post-application microbial 
counts corrected for Baseline of the A-D or B-D or C-D should be less than 
0.5 log10). 
Exploratory Objectives 
Evaluation of the investigational products consumption weight (product weight 
before application – product weight after application).

Statistical Methods: 
Subjects with treatment day baseline bacterial count in the range of 5.00 to 7.50 
log10/cm2, inclusive, on the groin will be included in the analysis. 
An alpha level of 5% will be used for all analyses. 
The following descriptive statistics for log10 CFU/cm2 and for log10 CFU/cm2 reductions 
from Baseline will be computed for each treatment, grouped by post application 
sampling time point (30 seconds, 10 minutes and/or Baseline, by case): mean, 
median, standard deviation, minimum, maximum, and count. 
Efficacy Analysis 
A linear regression model for each post-treatment sampling time point of immediate 
efficacy (30 seconds and 10 minutes post-application) will be used. In the model, the 
dependent variable used will be the post-treatment bacterial count (log10 CFU/cm2) 
and predictors will be the treatment as a fixed effect and the Baseline as a covariate. 
The ATE corrected for Baseline will be estimated from the model and compared to 
non-inferiority criteria. 
Safety Analysis 
All treated subjects will be considered evaluable for safety. Skin irritation scores will 
be reported for any subject who is scored with a 1 or more at any observation 
(treatment day, post-application/prior to 30 seconds and 10 minutes), in any category 
for any site. 
Adverse events (including post treatment skin irritation scores of 3), will also be 
summarized. Summary tables will present incidence rates of adverse events by 
treatment group for all subjects who enter the treatment period. Listings of adverse 
events will be provided.

Study Objectives 
2.1 
Efficacy objectives 
The objective of this study is to demonstrate immediate (30 seconds and 10 minutes) antimicrobial 
efficacy of three investigational products (26 ml Project X, 10.5 ml Project X and 5.1 ml Project X) 
compared to Prevantics® Maxi Swabstick 5.1 ml (active control) on the groin. 

 
 
Study Number: ER 19/232 
Professional Disposables International Inc. Confidential 
Page 8 of 32 
To demonstrate the immediate antimicrobial efficacy at 30 seconds and 10 minutes post-application 
the following criteria should be met on the groin: 
- 
non-inferiority of the ATE of the product A, B and C compared to product D (the upper 
two-sided 95% confidence bound of the post-application microbial counts corrected for 
Baseline of the A-D or B-D or C-D should be less than 0.5 log10). 
2.2 
Exploratory Objectives 
Evaluation of the investigational products consumption weight (product weight before application – 
product weight after application). 
2.3 
Safety objectives 
Safety will also be evaluated based on the incidence of adverse events reported during the study and 
assessment of skin irritation ratings from Appendix 17.6.

Study Design 
3.1 
Overall Study Design and Plan 
This study is designed to determine the antimicrobial effectiveness of three treatments (A, B 
and C), intended for use as Patient Preoperative Skin Preparation.  The testing methods are 
based on the standardized test method ASTM E1173-15, Evaluation of Preoperative, 
Precatheterization, or Preinjection Skin Preparations, and using the requirements specified by in 
the 2017 FDA 21 CFR Part 310, Safety and Effectiveness of Health Care Antiseptics; Topical 
Antimicrobial Drug Products for Over-the-Counter Human Use, Final Rule (December 20, 2017).  
The immediate antimicrobial efficacy will be evaluated in this study. 
At least 100 subjects will be treated bilaterally with two of the four test materials (A, B, C and 
Positive Control), one per each side of the groin test site. Subjects will undergo at least a 14-
day washout period before Treatment Day. During Treatment Day subjects who meet the 
Inclusion Criteria will be treated with the study products and samples will be taken before and 
after treatment application. The cup scrub technique will be used for sampling baseline, 30-
seconds and 10-minutes on the Treatment Day. 
The immediate antimicrobial efficacy at 30 seconds and 10 minutes post-application will be 
demonstrated if the non-inferiority of the ATE of the investigational products (A, B and C) 
compared to Positive Control (D) is met (the upper two-sided 95% confidence bound of the 
post-application microbial counts corrected for Baseline of the investigational products  A, B or 
C compared to the Positive Control should be less than 0.5 log10). 
3.2 
Study Type 
This is a randomized, single-center, single blind study in healthy subjects. The staff member(s) 
performing bacterial enumeration will be blinded from the identification of treatment assignment. 
3.3 
Endpoints 
- 
Log10 CFU/cm2 of skin flora at the groin site before and after each treatment at 30 seconds, 
10 minutes. 
- 
Skin irritation scores (Erythema, Edema, Rash, and Dryness) at each time interval and the 
incidence of AEs reported during the study. 
3.4 
Randomization and Blinding 
The randomization scheme for the study will be provided by the Research facility. 

 
 
Study Number: ER 19/232 
Professional Disposables International Inc. Confidential 
Page 9 of 32 
Each subject will receive two treatments. Assignment of products to the left or right side for each body 
area will be per a computer-generated randomization schedule. 
Specific sites of sampling for baseline and post application sampling time points will be randomized. 
Randomization will continue until required number of subjects with required treatment day baseline 
counts is enrolled. 
The PI is responsible for ensuring that the randomization is followed. The randomization schedule for 
the groin sites will be provided in a separate document. The study products will be labeled with the 
appropriate codes provided in Table 1.  
Each subject will be identified by their initials and a subject number for which they qualify. Inclusion 
subject numbers will be assigned at Treatment day. 
 
Washout subjects will be assigned numbers starting with 001 and the letter “P”: P001 
 
Treatment subjects will be assigned numbers with 001 and the letter “I”: I001 
The study products will not be blinded from the PI or other study staff performing the study material 
application or bacterial sample collections. The staff member(s) performing bacterial enumeration and 
the statistician will be blinded from the identification of treatment assignment. The study staff 
performing the bacterial enumeration will not be involved in the study products application or the 
collection of samples. The Raw Data Sheet sections of the CRF will be maintained separately (from the 
pages within the CRF which include study treatment identifications) during the conduct phase of the 
study. The study staff performing the bacterial enumeration will record counts directly onto the Raw 
Data Sheet pages of the CRF without accessing the subject study documentation folder containing the 
other CRF pages. The Raw Data Sheets will be compiled with the entire CRF after all data recording 
have been completed. 
The generated randomization scheme will contain the following treatment codes: P1, P2, P3 and P4 to 
ensure the blinding for the study statistician. The assignment between the treatment codes (P1, P2, 
P3 and P4) from the randomization scheme and the label treatment codes (A, B, C and D) will be made 
by the Sponsor in a separate document. 
In this study four products will be tested and each subject will receive two products in the same time, 
one on the left side and the other on the right side. More than 100 randomization schemes will be 
generated to compensate for the baseline requirement failure and to provide enogh evaluable sites. 
The block randomization method will be used to ensure equal sample size groups over time. Products 
will be randomized in blocks of 12 and sampling time points will be randomized in blocks of 6. 
Randomization scheme will be generated using an electronic online randomizer provided by Urbaniak 
et al. (2013). 
3.5 
Study Products 
The products identified in Table 1 will be used in the study. Specific product identification codes and 
lot numbers will be included with the clinical supplies when they are shipped to the Research facility.

3.11 Protocol Modifications 
 Protocol Amendments 
Protocol Amendments will not be implemented without prior agreement between the PI and PDI and 
prior submission and approval from the IRB/EC, except when necessary to eliminate an immediate 
hazard to the subject and to protect the safety and well-being of the subject. 
Will constitute Protocol Amendments for administrative inputs and changes: correction of typing 
mistakes, changes in study personnel (other than the PI) or contact information. Protocol Amendments 
for administrative inputs and changes has to be agreed between the PI and PDI and will be submitted 
to the IRB/EC but implementation may proceed without prior IRB/EC approval, unless so required by 
the IRB/EC or site SOPs.  
 Protocol Deviations 
A deviation is a departure from the protocol that will likely affect the safety, rights or welfare of subjects, 
the scope of the investigation, the integrity of the data or the scientific quality of the study. Protocol 
deviations are documented on a Protocol Deviation Form. 
Deviations that potentially affect 1) subject safety, rights or welfare, 2) data integrity or 3) compromise 
the statistical analysis of the study require communication to PDI at the earliest convenience.  
A Protocol Deviation Form must be completed by the PI or designated sub-investigator trained by the 
PI and checked and approved by PI and include a description of the circumstances surrounding and 
the reason for the deviation, any actions taken, and whether or not the subject was allowed to continue 
in the study. 
If during monitoring visits a deviation is identified, the Study Monitor will report it to the PI and PDI.

Page 14 of 32 
date the ICF if they wish to participate in the study. A copy of the ICF must be provided to the subject. 
A signed and dated ICF must be maintained in the PI study documentation file at all times. 
5 
Study Treatment 
These study procedures are based on the American Society for Testing and Materials (ASTM) “Standard 
Test Method for Evaluation of Preoperative, Precatheterization, or Preinjection Skin Preparations” 
(E1173-15). 
5.1 
Study Procedures 
 Washout Period 
The Inclusion/Exclusion Criteria will be reviewed with each subject to ensure eligibility for the study 
after subjects has signed the ICF.  
A skin irritation assessment using the scale from Appendix 17.6 will be performed by the PI or 
designated sub-investigator trained by the PI. If an irritation score of 1 for any individual skin condition 
is observed, the subject will be excluded from the study. 
Prior to the scheduled Treatment Day, subjects will undergo a minimum 14-day restriction. The subjects 
will be instructed to avoid contact with any topical or systemic antimicrobial products or any other 
product know to affect the normal microbial flora of the skin for the duration of their involvement in 
the study as written in the Subject Instructions for Main Study (Appendix 17.5.1). 
If it becomes necessary to take systemic antibiotics or to apply topical medications to the test areas 
within this Washout period, the subject must contact the PI or designated sub-investigator whom will 
inform the PI as soon as reasonably possible so that another volunteer may be recruited. 
Restrictions include, but are not limited to: 
- 
Use of antimicrobial soaps, shampoos, lotions, perfumes, after shaves, colognes, 
antiperspirants, deodorants 
- 
Contact with materials such as acids, bases, solvents 
- 
Swimming in chemically treated pools and bathing in hot tubs, spas and/or whirlpools 
- 
Use of tanning beds, hot waxes or depilatories (including shaving) 
Subjects will be provided a kit with non-antimicrobial personal care products for exclusive use during 
the study.  
If subjects require hair removal to facilitate sample collection, the subject will be asked to return to the 
test facility at approximately 48-96 hours prior to Treatment Day for clipping/re-clipping. 
Prior to performing the clipping/re-clipping before the Treatment Day, a skin irritation assessment using 
the scale from Appendix 17.6 will be performed by the PI or designated sub-investigator trained by the 
PI. If an irritation score of 1 for any individual skin condition is observed, the subject will be excluded 
from the study. 
Subjects will be required to refrain from bathing or showering 72 hours prior to Treatment Day. 
 Treatment Day 
The PI or a designated sub-investigator will complete the Treatment Day Inclusion/Exclusion Criteria 
CRF. If these criteria are satisfied, a skin irritation assessment using the scale from Appendix 17.6 will 
be performed prior to performing the Treatment Day baseline sample collection, by the PI or designated 
sub-investigator trained by the PI. If an irritation score of 1 for any individual skin condition at the 
Treatment Day baseline is observed, the subject will be excluded from the study.

5.1.2.1 Preparation of Test Areas on Treatment Day 
A Test Site Diagram for the groin test area is shown in Appendix 17.3. 
5.1.2.1.1 Preparation of Groin Test Area 
The test site within the groin region (groin test area) is defined as the inner aspect of the uppermost 
thigh, one inch parallel distance to the inguinal crease and where skin to skin contact is expected. 
Where subjects present with deep inguinal folds at the crease, the sampling distance from the crease 
may be increased to avoid skin folds in the sampling area. The corners of each groin test area will be 
marked directly on the skin using a non-toxic skin marker. Three sampling sites will be numbered within 
each groin test area, on each side of the groin region. The positioning and numbering of the groin 
sampling sites are standard for all subjects. Sampling sites on the contra-lateral side of the groin will 
be numbered in a mirror-image orientation. The three sampling sites within each test area represent 
one baseline (pre-prep) site and two post-prep sample sites (30 seconds and 10 minutes). 
Test sites for the investigational product and active control applicator on the groin will be 1.5’’ x 5’’ 
(3.81 cm x 12.7 cm) in area, occur at the uppermost inner aspects of both thighs, and appear to be 
similar in condition. 
After groin test areas are marked and sample sites numbered, baseline samples will be collected from 
the appropriate site per the randomization schedule in each test area using the scrub cup technique 
(section 5.2.1). 
5.1.2.2 Study Products Application 
The randomization schedule will designate the treatment to each side of the groin. 
Following baseline sample collection, randomly assigned contra-lateral test areas will be treated with 
the applicable study products. The post-application sampling times will be randomized among the 
sampling sites within a test area. 
The study products will be applied and the sampling configurations will be performed per the 
randomization scheme and the Treatment Application Instructions (Appendix 17.6). The duration of 
each application procedure will be recorded on the appropriate CRF. The study products, body area, 
application and dry times and treatment area are summarized in Table 2.

5.1.2.3 Timing of Post Application Sample Collection 
Microbial samples will be collected at 30 seconds (+5 seconds) and 10 minutes (± 30 seconds), post 
treatment application for both left side and right side. Post application timing begins upon completion 
of the study product application, including drying time. Microbial samples will be collected using the 
scrub cup technique (section 5.2.1). 
A skin irritation assessment using the scale from Appendix 17.7 will be performed by the PI or 
designated sub-investigator trained by the PI prior to collection of each post treatment microbial sample 

 
 
Study Number: ER 19/232 
Professional Disposables International Inc. Confidential 
Page 16 of 32 
collection (30 seconds and 10 minutes) and a corresponding rating score for each individual skin 
condition will be recorded in the subject’s CRF.  
If an irritation score of 3 for any individual skin condition at any post treatment observation is assigned, 
the subject will be discontinued from the study and an adverse event will be recorded. See Section 8.3 
(Adverse Events). 
Following final sample collection, the remaining study material will be removed from the subjects’ skin 
with water and soap as necessary and dried with paper towels. 
5.2 
Microbiological Methods 
 Microbial Sample Collection / Cup Scrub Technique 
Quantitative cultures (treatment day baselines and post treatment samples) will be obtained by a 
modification of the cylinder sampling technique of Williamson-Kligman cup scrub technique following 
ASTM E1874-14 “Standard Test Method for Recovery of Microorganisms from Skin using the Cup Scrub 
Technique”. To collect the samples, a sterile scrub cup (2.20 cm I.D.) will be placed on the site and 
held firmly to the skin. 3.0 ml of SSF++ will be pipetted into the cup and the skin will be scrubbed in 
a circular motion with moderate pressure for 1 minute using a sterile rubber policeman. Using a sterile 
transfer pipette, the SSF++ will be removed and placed in a sterile test tube. An additional 3.0 ml of 
fresh SSF++ will be pipetted into the cup and the scrub procedure will be repeated. This solution will 
be pooled with the first solution collected. 
 Bacterial Enumeration Methods 
Following sample collection, vortex the sample for 15 seconds and 10-fold serial dilutions will be 
prepared using PBW. One ml aliquots of appropriate dilutions will be pour-plated in TSA+N. Samples 
must be plated within 30 minutes of collection. 
Serial dilutions of collected treatment day samples as follows: 
for groin sites: 
- 
Baseline: 3 serial dilutions (10-3, 10-4 and 10-5) 
- 
30 seconds: 4 serial dilutions (100, 10-1, 10-2 and 10-3) 
- 
10 minutes: 4 serial dilutions (100, 10-1, 10-2 and 10-3) 
After 72 ± 4 hours of aerobic incubation at 30 ± 2˚C, colonies will be manually counted and viable 
cells in the original sample will be calculated according to SOPs. After incubation, plates may be 
refrigerated up to 48 hours prior to counting. 
Bacterial colonies enumerated manually within the countable range 25-250 from each dilution will be 
recorded on the appropriate CRFs for each subject. The average number of microorganisms recovered 
(CFU/cm2) from the skin during treatment day will be calculated using the formula to convert the 
volume of sample collected into log10CFU/cm2 of skin:

Assessment of Safety 
8.1 
Safety Parameters 
The principal measures of safety will be skin irritation scores and the incidence of adverse events 
reported during the study. 

 
 
Study Number: ER 19/232 
Professional Disposables International Inc. Confidential 
Page 18 of 32 
Adverse events will be captured from the time the subject have signed the Informed consent form to 
the time of subject discharge from the study. Adverse events will be categorized in relationship to the 
product that was applied to the specific skin site. All local and systemic adverse events observed or 
reported to the investigator will be evaluated.  
The severity, duration, causal relationship to the study product and study procedure, action taken 
(study related and subject related), study impact, outcome of the event; will be described for all adverse 
events. 
8.2 
Assessment Methods for Skin Irritation 
All randomized subjects will be considered evaluable for safety. Skin irritation scores based on the scale 
from Appendix 17.6 will be reported for any subject who is scored with a 1 or more at any observation 
(baseline treatment day, clipping/re-clipping and prior/post-application to 30 seconds and 10 minutes 
sampling procedures), in any category for any site. 
Adverse events (including post treatment skin irritation scores of 3), will also be summarized.  Summary 
tables will present incidence rates of adverse events by treatment group for all subjects who enter the 
treatment period. Listings of adverse events will be provided. 
A corresponding rating score for each individual skin condition, for each site will be recorded in the 
subject’s CRF. (See Appendix 17.6, which includes the following four independent evaluation 
categories: Erythema, Edema, Rash, and Dryness). 
If an irritation score of 1 or greater for any individual skin condition prior to the baseline sample 
collection (at treatment day phase) is assigned, the subject will be excluded from the study (no study 
treatment will be applied). 
If an irritation score of 3 for any individual skin condition at any observation period is assigned, the 
subject will be discontinued from the study and an adverse event will be recorded. See Section 8.3 
(Adverse Events). 
8.3 
Adverse Events 
The PI is responsible for identifying adverse events that occur to each subject throughout the study 
and follow-up period. An adverse event can occur at any time during the conduct of the study, in any 
phase of the study or after the study is completed. An adverse event can be identified by the PI or 
sub-investigators or reported by the subject. 
Definitions: 
Adverse Event/Experience 
An Adverse Event/Experience is any unexpected or undesirable experience occurring to a subject during 
a study, which may or may not be related to the test product.  
All adverse events, regardless of severity or the causal/effect relationship, will be recorded. The severity 
of the effect will be noted as Mild, Moderate, or Severe according the following definitions: 
Mild 
 
Awareness of signs or symptom, but easily tolerated. 
Moderate 
Discomfort to a degree as to cause interference with normal daily life activities and 
/or requiring medication. 
Severe 
Incapacity with inability to work or do usual daily life activities and requiring medical 
attention/intervention. 
Causal Relations of Adverse Event/Experience 
When determining the causal/effect relationship to the test product, the relationship will be described 
as Not related, Unlikely related, Possibly related or Related. 

 
 
Study Number: ER 19/232 
Professional Disposables International Inc. Confidential 
Page 19 of 32 
The following definitions will be utilized: 
Not related 
No association to the test product. Related to other etiologies such as 
concomitant medications or conditions or subject’s known clinical state. 
Unlikely related  
Uncertain association. Other etiologies are also possible. 
Possibly related 
Clear-cut association with improvement upon withdrawal of the test 
product. Not reasonably explained by the subject’s known clinical state. 
Related 
An adverse event with a clear-cut temporal association with exposure to 
study materials and cannot reasonably be explained by the subject’s known 
clinical state. Association with study material is confirmed by laboratory 
testing if possible. 
Serious Adverse Event/Experience 
A Serious Adverse Event/Experience is any adverse experience occurring at any dose that results in 
any of the following outcomes: 
- 
Death; 
- 
A life-threatening adverse drug experience; 
- 
Inpatient hospitalization or prolongation of existing hospitalization; 
- 
A persistent or significant disability/incapacity; 
- 
Congenital anomaly/birth defect; 
- 
An important medical event that may require medical or surgical intervention to prevent one 
of the previously listed outcomes. 
Unexpected Adverse Event/Experience 
An Unexpected Adverse Event/Experience is any adverse drug event/experience not listed in the current 
labeling for the test product or the current IB. Where test product labeling or IB is not available, 
anticipated experiences will be based on the known pharmacological/toxicological properties of the test 
product or ingredients. 
Follow-up: 
If an adverse event/experience occurs, the subject under the direction of the PI or designated sub-
investigator trained by the PI may be referred to the nearest acute care facility for treatment. Serious 
or Unexpected Drug Event/Experience will be followed to resolution. Any adverse event will be 
documented on an Adverse Event Report Form. 
Recording and Reporting 
The PI or designee records all adverse events on an Adverse Event Form in the subject’s CRF.  
The PI must promptly report all treatment related adverse events to the PDI study monitor.  
All SAE must be reported to the: 
- 
Sponsor within 24 hours of the PI awareness/notification of the event. 
- 
IRB/IEC within 10 working days of the PI awareness/notification of the event. 
If a subject has no adverse event during the study, the absence of such must be recorded on the CRF.

Statistics 
9.1 
Data sets analyzed 
A modified intent to treat data set will be used for efficacy analysis. Subjects with treatment day 
baseline bacterial count in the range of 5.00 to 7.50 log10/cm2, inclusive, on the groin will be included 

 
 
Study Number: ER 19/232 
Professional Disposables International Inc. Confidential 
Page 20 of 32 
in the modified intent to treat data set. The acceptability of each bilateral baseline site (left or right) 
will be assessed separately for inclusion in the modified intent to treat data set. The exclusion of 
subjects who do not meet treatment day baseline requirements and the exclusion of either left or right 
groin sites without exclusion of the subject as a whole makes this data set a modified intent to treat 
data set.  
A per protocol data set will also be used for efficacy analysis. Subjects included in the modified intent 
to treat data set with no major protocol deviations and no missing for one or more of the 30 minutes 
and 10 minutes time points will be included in the per protocol data set. The acceptability of each 
bilateral site (left or right) will be assessed separately for inclusion in the per protocol data set. 
The full intent to treat data set (all randomized subjects) will be used for safety analysis. 
9.2 
Sample Size 
This evaluation will be performed with an estimated of a minimum of 50 evaluable sites per product 
with qualifying treatment day microbial baseline counts. No sample size calculation was performed to 
provide statistically-powered evidence of efficacy as part of this study. 
9.3 
Efficacy Analyses 
An alpha level of 5% will be used for all analyses. 
The following descriptive statistics for log10 CFU/cm2 and for log10 CFU/cm2 reductions from Baseline 
will be computed for each treatment, grouped by body area and each post application sampling time 
point (30 seconds, 10 minutes and/or Baseline, by case): mean, median, standard deviation, minimum, 
maximum, and count. 
The statistician will be blinded to the treatment during the analysis phase.  
 Efficacy Analysis 
A linear regression model for each post treatment sampling time point of immediate efficacy (30 
seconds and 10 minutes post-application) will be used. In the model, the dependent variable used will 
be the post treatment bacterial count (log10 CFU/cm2) and predictors will be the treatment as a fixed 
effect and the Baseline as a covariate. The ATE corrected for Baseline will be estimated from the model 
and compared to non-inferiority criteria. 
9.4 
Safety Analysis 
All treated subjects will be considered evaluable for safety. Skin irritation scores will be reported for 
any subject who is scored with a 1 or more at any observation (baseline treatment day, post-
application/prior to 30 seconds and 10 minutes sampling procedures), in any category for any site. 
Adverse events (including post treatment skin irritation scores of 3), will also be summarized. Summary 
tables will present incidence rates of adverse events by treatment group for all subjects who enter the 
treatment period. Listings of adverse events will be provided. 
9.5 
Procedures for Accounting for Missing, Unused, and Spurious Data 
Missing microbiological data at 30 seconds, or 10 minutes, such as due to laboratory error or subject 
lost to follow-up, will be reported as missing and will not be imputed. Inclusion of these subjects in the 
per-protocol data set will be based on the criteria defined above. Details of any missing data and 
rationale for inclusion/exclusion in the per-protocol data set will be described in the study report.
