5 INTRODUCTION 
5.1 Rationale and Background 
Daily wear contact lenses are worn during waking hours, often for a full day and then 
removed for cleaning and disinfection prior to reinsertion the following day. Frequent 
replacement daily wear contact lenses are replaced according to the product package insert 
provided by the contact lens manufacturer. 
New silicone hydrogel materials continue to be developed, possessing unique material 
properties and superior oxygen transmissibility over contact lenses made with conventional 
hydrogel materials. A new lens, 
 has been developed in an 
effort to maintain sustained performance by providing an inherently wettable core material 
with a water gradient surface. The new silicone hydrogel lens has been designed to provide 
favorable performance for daily wear with 1-month replacement. 
In this clinical study, the clinical performance of the investigational 
 contact lens will 
be assessed and the 
 contact lens will be compared to the commercially available 
AOHP contact lens in a crossover design, both to be worn in a daily wear modality for 
approximately 1 month. 
5.2 Purpose of the Study 
The purpose of this study is to assess the clinical performance of the investigational 
 
contact lens over 30 days of daily wear compared to AOHP. The primary endpoint was 
selected to address the primary objective of the study. Procedures for measurement of these 
endpoints were selected based on common practice for these assessments. The design of this

study is justified based upon preclinical and clinical testing, as described within the 
Investigator’s Brochure. AOHP contact lenses were chosen as the comparator product 
because like the test product these lenses are frequent replacement daily wear contact lenses.. 
At the end of the study, a clinical study report will be prepared in accordance with applicable 
regulatory requirements and standards.  
There are no immediate plans to submit the results of this study for publication; however, the 
results may be offered for publication if they are of scientific interest, or if the results relate 
to a product that is subsequently approved or cleared for marketing. Alcon reserves the right 
of prior review of any publication or presentation of information related to the study. The 
author(s) of the publication will be the individual with substantial contribution to the 
conception or design of the work, OR the acquisition, analysis, or interpretation of data. 
Additionally, the author will draft the work or revise it critically for important intellectual 
content; provide final approval of the version to be published; and agree to be accountable for 
all aspects of the work, ensuring that questions related to the accuracy or integrity of any part 
of the work are appropriately investigated and resolved. 
5.3 Risks and Benefits 
The clinical investigation process risks are managed through appropriate training and 
monitoring according to the protocol-specific monitoring plan. Investigational device risks, 
including risks associated with use of device and methods and procedures for application of 
device, are defined in the investigator’s brochure and/or product labeling and are managed 
through review of safety assessments outlined in this protocol.  
Contact lenses may offer improved peripheral vision and the convenience of not wearing 
spectacles. Material properties and design characteristics of 
 contact lenses are 
features consistent with successful contact lens wear. Based upon nonclinical testing and 
documented rationale for applicability of test results, 
 contact lenses are assessed to 
be nontoxic and biocompatible for on-eye use. 
In the US, AOHP contact lenses have approved indications for use for both daily wear and 
extended wear for up to 6 nights/7 days of continuous wear. Further details on any known 
potential risks and benefits can be found in the product package insert. 
There may also be unknown risks to use of 
 contact lenses. Any risk to subjects in 
this clinical study will be minimized by compliance with the eligibility criteria and study 
procedures, clinical oversight, and monitoring.

Not applicable 
8 STUDY POPULATION 
The study population consists of male and female subjects aged 18 years or older who are 
current wearers of spherical weekly/monthly soft contact lenses in both eyes with at least 3 
months wearing experience, with a minimum wearing time of 5 days per week and 10 hours 
per day. One specific group of subjects will be recruited for this study: normal contact lens 
wearers. Normal (asymptomatic) subjects will be identified using a symptomatology 
questionnaire, 
 
 
This study aims to enroll (consent) approximately 160 subjects in 
approximately 10 US sites, with a target of 152 randomized and 144 completing the study, 
with 16 (intended minimum) to 22 (intended maximum) subjects per site. Additional subjects 
may be enrolled at specific sites with prior sponsor approval. Site-specific targets may vary 
based upon individual site capabilities. Estimated time needed to recruit subjects for the study 
is approximately 6 weeks; however, unanticipated circumstances may shorten or lengthen this 
time and would not require amendment of this protocol.  
8.1 Inclusion Criteria 
Written informed consent must be obtained before any study specific assessment is 
performed. Upon signing informed consent, the subject is considered enrolled in the study. 
Subjects eligible for inclusion in this study must fulfill all of the following criteria:

10.4.2 Discontinuations 
Discontinued subjects are individuals who voluntarily withdraw or are withdrawn from the 
study by the investigator after signing informed consent. 
Subject numbers of discontinued subjects must not be re-used (i.e., subject replacement is not 
allowed). 
Subjects may discontinue from study or study treatment at any time for any reason. Subjects 
may also be discontinued from study treatment at any time if, in the opinion of the 
investigator, continued treatment poses a risk to their health. 
For subjects discontinuing from the study, the investigator must complete all Exit procedures 
according to Table 3-1 Schedule of Study Procedures and Assessments, if the subject is 
willing and able, and if in the opinion of the investigator it is safe for the subject to do so. 
The investigator must document the reason for study or treatment discontinuation in the 
subject’s case history source documents. 
To ensure the safety of all subjects who discontinue early, investigators must assess each 
subject and, if necessary, advise them of any therapies and/or medical procedures that may be 
needed to maintain their health. 
10.4.3 Schedule of Procedures and Assessments for Subjects Discontinued 
from Investigational Product

Device Deficiencies 
A device deficiency is inadequacy of a medical device with respect to its identity, quality, 
durability, reliability, safety, or performance. A device deficiency may or may not be 
associated with patient harm (i.e., ADE or SADE); however, not all ADEs or SADEs are due 
to a device deficiency. The investigator should determine the applicable category listed in the 
Device Deficiency eCRF for the identified or suspect device deficiency and report any 
patient harm separately. Examples of device deficiencies include the following:  
• 
Failure to meet product specifications (e.g., incorrect lens power/diameter/base 
curve/color) 
• 
Lens/solution cloudy 
• 
Lens surface/edge defect  
• 
Torn lens during handling/in pack

Packaging deficit (e.g., mislabeled product, tampered seal, leaking bottle/container) 
• 
Suspect product contamination 
• 
Lack of performance  
11.2 Monitoring for Adverse Events 
At each visit, after the subject has had the opportunity to spontaneously mention any 
problems, the investigator should inquire about AEs by asking the standard questions shown 
below and report as applicable: 
• 
“Have you had any health problems since your last study visit?” 
• 
“Have there been any changes in the medicines you take since your last study visit?” 
In addition, changes in any protocol-specific parameters 
 evaluated 
during the study are to be reviewed by the investigator. Any untoward (unfavorable and 
unintended) change in a protocol-specific parameter 
 that is 
clinically relevant, in the opinion of the investigator, is to be reported as an AE. These 
clinically relevant changes will be reported regardless of causality.  
11.3 Procedures for Recording and Reporting 
AEs are collected from the time of informed consent Any preexisting medical conditions or 
signs/symptoms present in a subject prior to the start of the study (i.e., before informed 
consent is signed) are not considered AEs in the study and should be recorded in the Medical 
History section of the eCRF. 
In addition, temporary lens awareness or visual changes during the fitting process are not 
considered AEs if the investigator assesses that the symptom(s) can reasonably resolve within 
the anticipated adaptation period.  
For each recorded event, the ADEs and SAEs documentation must include: date of 
occurrence, severity, treatment (if applicable), outcome, and assessments of the seriousness 
and causality. In addition, the investigator must document all device deficiencies reported or 
observed with test and comparator products on the Device Deficiency eCRF. The site must 
submit all available information on ADEs, SAEs, and device deficiencies to the study 
sponsor immediately as follows:  
• 
All SAEs must be reported immediately (within 24 hours) of the investigator’s or 
site’s awareness.

• 
ADEs that do not meet seriousness criteria and device deficiencies must be reported 
within 10 calendar days of the investigator’s or site’s awareness.  
• 
A printed copy of the completed Serious Adverse Event and Adverse Device Effect 
and/or Device Deficiency eCRF must be included with product returns 
• 
Additional relevant information after initial reporting must be entered into the eCRF as 
soon as the data become available. 
• 
Document any changes to concomitant medications on the appropriate eCRFs. 
• 
Document all relevant information from Discharge Summary, Autopsy Report, 
Certificate of Death, etc., if applicable, in narrative section of the Adverse Device 
Effect (for related AEs) and Serious Adverse Event eCRF. 
Note: Should the EDC system become nonoperational, the site must complete the 
appropriate paper Serious Adverse Event and Adverse Device Effect and/or Device 
Deficiency Form. The completed form is emailed to the study sponsor at 
msus.safety@Alcon.com according to the timelines outlined above; however, the 
reported information must be entered into the EDC system once it becomes 
operational. 
Any AEs and device deficiencies for nonstudy marketed devices/products (i.e. CLEAR 
CARE Cleaning & Disinfecting Solution, LacriPure (or equivalent)) will be considered and 
processed as spontaneous (following the postmarket vigilance procedures) and should be 
communicated to the device’s/product’s manufacturer as per local requirements. 
Study sponsor representatives may be contacted for any protocol related question and 
their contact information is provided in the Manual of Procedures that accompanies 
this protocol. 
Further, depending upon the nature of the AE or device deficiency being reported, the study 
sponsor may request copies of applicable portions of the subject’s medical records. The 
investigator must also report all AEs and device deficiencies that could have led to a SADE 
according to the requirements of regulatory authorities or IRB/IEC. 
Intensity and Causality Assessments 
Where appropriate, the investigator must assess the intensity (severity) of the AE based on 
medical judgment with consideration of any subjective symptom(s), as defined below: 
Intensity (Severity) 

Document ID: 
V-CLN-0011453 
Status: Approved, Version: 2.0 
Approved Date: 01 Sep 2021 
Page 48 of 62 
 
Alcon – Business Use Only 
Mild  
An AE is mild if the subject is aware of but can easily tolerate the sign or 
symptom. 
Moderate  
An AE is moderate if the sign or symptom results in discomfort significant 
enough to cause interference with the subject’s usual activities. 
Severe  
An AE is severe if the sign or symptom is incapacitating and results in the 
subject’s inability to work or engage in their usual activities. 
For every AE in the study, the investigator must assess the causality (Related or Not Related 
to the medical device or study procedure). An assessment of causality will also be performed 
by study sponsor utilizing the same definitions, as shown below: 
Causality 
Related 
An AE classified as related may be either definitely related or possibly related 
where a direct cause and effect relationship with the medical device or study 
procedure has not been demonstrated, but there is a reasonable possibility that 
the AE was caused by the medical device or study procedure. 
Not Related  An AE classified as not related may either be definitely unrelated or simply 
unlikely to be related (i.e., there are other more likely causes for the AE). 
The study sponsor will assess the AEs and may upgrade the investigator’s assessment of 
seriousness and/or causality. The study sponsor will notify the investigator of any AEs that is 
upgraded from nonserious to serious or from unrelated to related. 
11.4 Return product analysis, if applicable 
Study sponsor representatives and their contact information are provided in the MOP that 
accompanies this protocol.  
Alcon study products associated with device deficiencies and/or product related AEs should 
be returned and must include the Complaint # which will be provided by study sponsor after 
the case is entered in the study sponsor’s Global Product Complaint Management System 
(GPCMS). 
11.5 Unmasking of the Study Treatment  
Masked information on the identity of the assigned medical device should not be disclosed 
during the study (see Section 9.4). If the treatment code needs to be broken in the interest of

subject safety, the investigator is encouraged to contact an appropriate study sponsor 
representative prior to unmasking the information if there is sufficient time. Dependent upon 
the individual circumstances (i.e., medical emergency), the code may be broken prior to 
contact with the study sponsor. The study sponsor must be informed of all cases in which the 
code was broken and of the circumstances involved. Additionally, the study sponsor may be 
required to unmask the information in order to fulfill expedited regulatory reporting 
requirements. 
11.6 Follow-Up of Subjects with Adverse Events  
The investigator is responsible for adequate and safe medical care of subjects during the 
study and for ensuring that appropriate medical care and relevant follow-up procedures are 
maintained after the study.  
The investigator should provide the study sponsor with any new safety information (which 
includes new AEs and changes to previously reported AEs) that may affect the safety 
evaluation of the device. For AEs that are unresolved/ongoing at time of discontinuation, any 
additional information received at follow-up should be documented in the eCRFs up to study 
completion (i.e., database lock). Any additional data received up to 3 months after subject 
completed the study should be documented and available upon the study sponsor’s request. 
All complaints received after this time period will be considered and processed as 
spontaneous (following the postmarket vigilance procedures) and should be communicated to 
the medical device’s manufacturer as per local requirements. The investigator should also 
report complaints on non-Alcon products directly to the manufacturer as per the 
manufacturer’s instructions or local regulatory requirements. 
11.7 Pregnancy in the Clinical Study 
Women of childbearing potential or women who are pregnant at the time of study entry are 
not excluded from participation. Pregnancy should be included in the appropriate eCRF when 
a pregnant woman enters the study or if a woman becomes pregnant during the study. 
Pregnancy is not reportable as an AE; however, complications may be reportable and will be 
decided on a case–by-case basis.  
12 ANALYSIS PLAN 
Continuous variables will be summarized using the number of observations, mean, standard 
deviation (SD), median, minimum, and maximum, as well as confidence intervals (CIs) or

12.4 Effectiveness Analyses 
This study defines 1 primary
 
endpoint .
 FAS as the primary analysis set. 
 
 
 
 
 
  
12.4.1 Analysis of Primary Effectiveness Endpoint(s) 
The primary objective of this study is to demonstrate noninferiority in VA at distance when 
wearing 
compared to AOHP. The primary endpoint is distance VA with study lenses 
at Day 30, collected for each eye in logMAR. 
12.4.1.1 Statistical Hypotheses 
The null and alternative hypotheses are formulated in terms of the predefined margin of 0.05 
for noninferiority: 
H0: μ(T) – μ(C) ≥ 0.05 
Ha: μ(T) – μ(C) < 0.05 
where μ(T) and μ(C) denote the mean distance VA for 
and AOHP, respectively, on the 
logMAR scale. 
12.4.1.2 Analysis Methods 
A mixed effects repeated measures model will be utilized to test these hypotheses. The model 
will include terms for lens, visit, lens by visit interaction, period, and sequence. Within-
subject correlation due to eye and the crossover design will also be accounted for in the 
model. Lens difference 
 and the corresponding one-sided 95% upper 
confidence limit will be computed at Day 30. Noninferiority in distance VA will be declared 
if upper confidence limit is less than 0.05.

12.5 Handling of Missing Data 
All data obtained in evaluable subjects/eyes will be included in the analysis. No imputation 
for missing values will be carried out 
 
 
12.6 Safety Analyses 
The safety endpoints are:  
• AEs 
• Biomicroscopy findings 
• Device Deficiencies 
There are no safety hypotheses planned in this study. The focus of the safety analysis will be 
a comprehensive descriptive assessment of occurrence of adverse events as well as the other 
listed parameters. 
All AEs occurring from the time a subject signs informed consent to study exit will be 
accounted for in the reporting. Safety analyses will be conducted using the safety analysis set 
on a treatment-emergent basis. Descriptive summaries (frequencies and percentages) for 
ocular and nonocular AEs will be presented by Medical Dictionary for Regulatory Activities 
Preferred Terms. AEs leading to study discontinuation and SAEs will be identified. 
Individual subject listings will be provided, as necessary. 
Individual subject listings will be provided for AEs that occur after signing informed consent 
but prior to exposure to IP. 
Each biomicroscopy parameter will be tabulated by its grade. For each biomicroscopy 
parameter, counts and percentages of eyes that experience an increase of ≥ 2 grades from 
baseline (last assessment prior to study lens exposure in each period) to any subsequent visit 
within the same period will be presented. A supportive listing will be generated which will 
include all biomicroscopy data from all visits within the same period for those eyes 
experiencing the increase. 
Two listings for device deficiencies, prior to exposure to study contact lenses and treatment-
emergent, will be provided. Additionally, each device deficiency category will be tabulated. 
No inferential testing will be conducted for the safety analyses.

13 DATA HANDLING AND ADMINISTRATIVE REQUIREMENTS 
13.1 Subject Confidentiality 
The investigator must ensure that the subject’s identity is kept confidential throughout the 
course of the study. In particular, the investigator must keep an enrollment log with 
confidential identifying information that corresponds to the subject numbers and initials of 
each study participant. The study sponsor may collect a copy of the enrollment log without 
any directly identifying subject information.  
The study sponsor may share patient-level data collected in this trial with qualified 
researchers to help facilitate product development or enhancements in research that is not 
directly related to the study objectives. The Informed Consent explains this to the study 
subject.  
13.2 Completion of Source Documents and Case Report Forms 
The nature and location of all source documents will be identified to ensure that original data 
required to complete the CRFs exist and are accessible for verification by the site monitor, 
and all discrepancies shall be appropriately documented via the query resolution process. Site 
monitors are appointed by the study sponsor and are independent of study site staff. 
If electronic records are maintained, the method of verification must be determined in 
advance of starting the study.  
At a minimum, source documents include the following information for each subject: 
• 
Subject identification (name, sex, race/ethnicity) 
• 
Documentation of subject eligibility 
• 
Date of informed consent

•
Dates of visits
•
Documentation that protocol specific procedures were performed
•
Results of study parameters, as required by the protocol
•
IP accountability records
•
Documentation of AEs and other safety parameters (if applicable)
•
Records regarding medical histories and the use of concomitant therapies prior to and
during the study
•
Date of study completion and reason for early discontinuation, if applicable
It is required that the author of an entry in the source documents be identifiable. Direct access 
to source documentation (medical records) must be allowed for the purpose of verifying that 
the data recorded on the CRF are consistent with the original source data. 
Only designated individuals at the site will complete the CRFs. The CRFs must be completed 
at regular intervals following the clinical study visit schedule. It is expected that all data 
reported have corresponding entries in the source documents. The principal investigator is 
responsible for reviewing and certifying that the CRFs are accurate and complete. The only 
subject identifiers recorded on the CRFs will be subject number, and subject demographic 
information.  
13.3 Data Review and Clarifications 
A review of CRF data to the subject’s source data will be completed by the site monitor to 
ensure completeness and accuracy. After the CRFs have been completed, additional data 
clarifications and/or additions may be needed as a result of the data cleaning process. Data 
clarifications are documented and are part of each subject’s CRF. 
13.4 Sponsor and Monitoring Responsibilities 
The study sponsor will select principal investigators that are qualified by education, training, 
and experience to assume responsibility for the proper conduct of this clinical trial.  
The study sponsor is financially funding this clinical trial and will compensate the 
investigator and/or the Institution(s) at which the study is conducted in accordance with a 
signed clinical trial agreement. 
The study sponsor will designate a monitor to conduct the appropriate site visits at the 
appropriate intervals according to the study monitoring plan. The clinical investigation will

be monitored to ensure that the rights and well-being of the subjects are protected, the 
reported data are accurate, complete, and verifiable from the source documents, and the study 
is conducted in compliance with the current approved protocol (and amendments[s], if 
applicable), with current GCP, and with applicable regulatory requirements. 
The site may not screen subjects or perform the informed consent process on any subject 
until it receives a notification from an appropriate study sponsor representative that the site 
may commence conducting study activities. Monitoring will be conducted periodically while 
the clinical study is ongoing. Monitoring methods may include site visits, telephone, written 
and fax correspondence. Close-out visits will take place after the last visit of the last subject 
at the site. 
A coordinating investigator may be identified by the study sponsor to review and endorse the 
final study report. In cases where a coordinating investigator is engaged, the study sponsor 
will select the coordinating investigator based upon their experience, qualifications, active 
study participation, and their willingness and availability to take on this role. 
13.5 Regulatory Documentation and Records Retention 
The investigator is required to maintain up-to-date, complete regulatory documentation as 
indicated by the study sponsor and the investigator’s files will be reviewed as part of the 
ongoing study monitoring. Financial information is to be kept separately.  
Additionally, the investigator must keep study records and source documents consistent with 
the terms of the clinical study agreement with the study sponsor. If the investigator retires, 
relocates, or for any other reason withdraws from responsibility of keeping the study records, 
then the study sponsor must be notified and suitable arrangements made for retention of study 
records and source documents needed to comply with national and international regulations. 
13.6 Quality Assurance and Quality Control 
The study sponsor will secure agreement from all involved parties to ensure direct access to 
all study related sites, source data and documents, and reports for the purpose of monitoring 
and auditing by the study sponsor, and inspection by domestic and foreign regulatory 
authorities. Quality control will be applied to each stage of data handling to ensure that all 
data are reliable and have been processed correctly. Agreements made by the study sponsor 
with the investigator/institution and any other parties involved in the clinical study will be 
provided in writing as part of the protocol or as a separate agreement.
