Serious Adverse Event (SAE)
Adverse event that led to any of the following:

Death.

A serious deterioration in the health of the subject 
that either resulted in:
a. a life-threatening illness or injury.
Note: Life-threatening means that the 
individual was at immediate risk of death from 
the event as it occurred, ie, it does not include 
an event which hypothetically might have 
caused death had it occurred in a more severe 
form.
b. any potentially sight-threatening event or 
permanent impairment to a body structure or a 
body function.
c. in-patient hospitalization or prolonged 
hospitalization.
Note: Planned hospitalization for a pre-
existing condition, without serious 
deterioration in health, is not considered a 
serious adverse event. In general, 
hospitalization signifies that the individual 
remained at the hospital or emergency ward 
for observation and/or treatment (usually 
involving an overnight stay) that would not 
have been appropriate in the physician's office 
or an out-patient setting. Complications that 
occur during hospitalization are adverse 
events. If a complication prolongs 
hospitalization or fulfills any other serious 
criteria, the event is serious. When in doubt as 
to whether “hospitalization” occurred, the 
event should be considered serious.
d. a medical or surgical intervention to prevent 
a) or b).

INTRODUCTION
5.1
Rationale and Background
 
 
 
 
  
New SiHy materials continue to be developed possessing unique material properties and 
superior oxygen transmissibility over contact lenses made with conventional hydrogel 
materials. A new lens,
 is being developed in an effort to maintain 
sustained performance 
 
 
 
 
 
In this clinical study, the performance of the investigational 
 lens will be compared to 
the commercially available Biofinity lens in a contralateral design with 2 days (including 1 
night of extended wear) exposure. The intended use of this contact lens is for vision 
correction. Therefore, the objective measurement of VA is planned as the primary variable for 
the comparison with the Biofinity lens. 
 
 
 
 
 
5.2
Purpose of the Study
The purpose of this clinical study is to evaluate the on-eye performance of the investigational 
 lens compared to the commercially available Biofinity lens following 1 night of 
extended wear. At the end of the study, a clinical study report will be prepared, in accordance 
with applicable regulatory requirements and standards.

5.3
Risks and Benefits
Contact lenses may offer improved peripheral vision and the convenience of not wearing 
spectacles. Material properties and design characteristics of 
 lenses are features 
consistent with successful contact lens wear. Based upon nonclinical testing and documented 
rationale for applicability of test results, 
 lenses are assessed to be non-toxic and 
biocompatible for on-eye use. 
Biofinity lenses are for up to 6 nights/7 days of continuous wear. Further details on any 
known potential risks and benefits can be found in the package insert.
A summary of the known potential risks and benefits associated with 
 can be found 
in the IB. 
 
 
 
 In general, the risks with 
are anticipated to be similar to other marketed weekly/monthly soft contact lenses.

INVESTIGATIONAL PLAN
7.1
Study Design
This will be a prospective, randomized, controlled, double-masked, contralateral wear 
clinical trial.
Approximately 1 site in the US will enroll approximately 12 subjects. Subjects will be 
randomized to wear the test 
 lens in one eye and the control Biofinity lens in the 
other eye. Subjects will be expected to attend 4 visits: Baseline/Dispense, Follow-up just 
prior to sleeping, Follow-up upon awakening/eye opening the morning following overnight 
lens wear, and Follow-up/Exit approximately 1 hour after awakening.

Following randomization during the Baseline/Dispense Visit, study lenses will be dispensed 
to the subject. All study contact lenses are to be worn overnight for 1 night only. Subjects will 
be required to retire for approximately 8 hours (7-10 hours) of closed eye sleep with lenses in 
place. 
The study is expected to take approximately 3 weeks for completion.  
7.2
Rationale for Study Design 
 
 
 
 
 
  
Results from this feasibility study may be used to further guide product development 
 
 
  
7.3
Rationale for Duration of Treatment/Follow-Up
 
7.4
Rationale for Choice of Control Product
Biofinity contact lenses were chosen as the control product because this lens is a proper 
predicate device to compare to 
 lenses in regards to effectiveness and safety. Both 
 and Biofinity are silicone hydrogel lenses. Biofinity lenses are to be prescribed for 
up to 6 nights/7 days of continuous wear
 
The Biofinity spherical soft contact lenses are indicated for the optical 
correction of refractive ametropia (myopia and hyperopia) in phakic or aphakic persons with 
non-diseased eyes.

Other Medical Device or Medication Specified for Use During the 
Study
No other medical devices or medications are required to be used in conjunction with the 
treatments during the clinical study, including lubricating or re-wetting drops.
9.3
Treatment Assignment / Randomization
Subjects will be randomized in a 1:1 ratio to receive treatment with 
 or Biofinity in 1 
eye and the other lens in the fellow eye, as indicated below:
Sequence 1: 
 (OD) / Biofinity (OS)
Sequence 2: Biofinity (OD) / 
(OS) 
Only after signing the ICF, a subject will be assigned a subject number by the electronic data 
capture system. 
A randomization list will be generated using a validated system that automates the random 
assignment of treatment arms to randomization numbers in the specified ratio. Subjects will 
be assigned a treatment (lens sequence) according to the randomization list 
 
 The randomization list will be generated and maintained by
the Study Sponsor.
At Visit 1, all eligible subjects will be randomized via the EDC/IRT integration system to one 
of the lens sequences. The Investigator or delegate will access the respective system after 
confirming that the subject meets all the eligibility criteria. A randomization number will be 
automatically assigned to the subject according to the subject randomization list but will not 
be communicated to the site user. The EDC/IRT integration system will inform the site user 
of the treatment (lens sequence) assignment to be dispensed to the subject.

Subject numbers of discontinued subjects must not be re-used.
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.

Permanent vision loss as defined by loss of 2 or more lines of BCVA from enrollment 
visit that fails to resolve

Uveitis (anterior, intermediate, or posterior)

Corneal abrasion affecting ≥ 50% of corneal surface area
*NOTE: Culture samples (from the subject’s eyes, lenses, etc) must be taken [as described in 
the MOP; and documented in the narrative section(s) of the corresponding ADE-SAE eCRF], 
for any suspected ocular infection, including infiltrates with overlying epithelial defect.
Significant Non-Serious Adverse Events
A significant non-serious AE is a device-related, non-sight threatening AE that warrants 
discontinuation of any contact lens wear for greater than or equal to 2 weeks. In addition, the 
Investigator must report any occurrence of the following as a Significant Non- Serious 
Adverse Event:

Peripheral non-progressive non-infectious ulcers

All symptomatic corneal infiltrative events

Corneal staining score greater than or equal to Grade 3 (Refer to MOP for grading 
scales) 

Temporary vision loss as defined by loss of 2 or more lines of BCVA from enrollment 
visit that persists for 2 or more weeks

Neovascularization score greater than or equal to Grade 2 (Refer to MOP for grading 
scales) 
The above events are based upon the categories provided in the ISO 11980 and the US FDA 
Premarket Notification (510(k)) Guidance Document for Daily Wear Contact Lenses.
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 (ie, 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:


Packaging deficit (eg, mislabeled product)

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:

“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?”
Changes in any protocol-specific parameters and/or questionnaires evaluated during the 
study are to be reviewed by the Investigator. Any untoward (unfavorable and unintended) 
change in a protocol-specific parameter or questionnaire response 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 pre-existing medical conditions or 
signs/symptoms present in a subject prior to the start of the study (ie, 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. 

ADEs or SAEs are documented on the Serious Adverse Event and Adverse Device 
Effect eCRF within 24 hours of the Investigator’s or site’s awareness.

Device deficiencies are documented on the Device Deficiency eCRF within 24 hours 
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 Serious Adverse 
Event and Adverse Device Effect eCRF.
 
 
 
.
Any AEs and device deficiencies for non-study marketed devices/products, if applicable, 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 MOP 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 upon 
medical judgment with consideration of any subjective symptom(s), as defined below:
Intensity (Severity)
Mild
An AE is mild if the subject is aware of but can easily tolerate the sign or 
symptom.

Page 42 of 51
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 (ie, 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 
are upgraded from non-serious to serious or from unrelated to related.
Additionally, the Study Sponsor shall immediately conduct an evaluation of any 
unanticipated adverse device effect, including anticipated adverse events that occur in 
unanticipated severity or frequency. The results of this evaluation will be reported to FDA, 
the IRB, and participating Investigators within 10 working days upon receiving notification 
of the effect.
11.4 Return product analysis
IP associated with device deficiencies and/or product related AEs [ie, ADE or SADE] will be 
returned for investigation as detailed in the MOP.
11.5 Unmasking of the Study Treatment
Masked information on the identity of the assigned medical device should not be disclosed 
during the study. 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 (ie, 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 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 subject exit from 
study, any additional information received at follow-up should be documented in the eCRFs 
up to study completion (ie, database lock). 
Any additional data received up to 1 month after subject discontinuation or exit must 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, as applicable.
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
Pregnancy is not reportable as an AE; however, complications may be reportable and will be 
decided on a case–by-case basis. Should a woman become pregnant during study 
participation, the pregnancy will be documented on the Medical history eCRF.
12 ANALYSIS PLAN
Continuous variables will be summarized using the number of observations, mean, standard 
deviation (SD), median, minimum and maximum. Categorical variables will be summarized 
with counts and percentages from each category. Any deviations to the analysis plan will be 
updated during the course of the study as part of a protocol amendment or will be detailed in 
the clinical study report.

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. 
 
 
 
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 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.

The Investigator must ensure that all personnel involved in the conduct of the study are 
qualified to perform their assigned responsibilities through relevant education, training, and 
experience. The Investigator and all clinical study staff must conduct the clinical study in 
compliance with the protocol. Deviations from this protocol, regulatory requirements and/or 
GCP must be recorded and reported to the Sponsor prior to database lock. If needed, 
corrective and preventive action should be identified, implemented, and documented within 
the study records. Use of waivers to deviate from the clinical protocol is prohibited.
Before clinical study initiation, this protocol, the informed consent form, any other written 
information given to subjects, and any advertisements planned for subject recruitment must 
be approved by an IRB/IEC. The Investigator must provide documentation of the IRB/IEC 
approval to the Study Sponsor. The approval must be dated and must identify the applicable 
protocol, amendments (if any), informed consent form, assent form (if any), all applicable 
recruiting materials, written information for subject, and subject compensation programs. The 
IRB/IEC must be provided with a copy of the IB, any periodic safety updates, and all other 
information as required by local regulation and/or the IRB/IEC. At the end of the study, the 
Investigator must notify the IRB/IEC about the study’s completion. The IRB/IEC also must 
be notified if the study is terminated prematurely. Finally, the Investigator must report to the 
IRB/IEC on the progress of the study at intervals stipulated by the IRB/IEC.
Voluntary informed consent must be obtained in writing from every subject and the process 
shall be documented before any procedure specific to the clinical investigation is applied to 
the subject. The Investigator must have a defined process for obtaining consent. Specifically, 
the Investigator, or their delegate, must explain the clinical study to each potential subject and 
the subject must indicate voluntary consent by signing and dating the approved informed 
consent form. The subject must be provided an opportunity to ask questions of the 
Investigator, and if required by local regulation, other qualified personnel. The Investigator 
must provide the subject with a copy of the consent form written in a language the subject 
understands. The consent document must meet all applicable local laws and provide subjects 
with information regarding the purpose, procedures, requirements, and restrictions of the 
study, along with any known risks and potential benefits associated with the IP and the study,
