Study 
Procedures 
The study is divided into two study Periods. In Period I, subjects will attend a 
Screening visit (Week -4) and undergo the Bellafill skin test. At Visit 1 (Day 
0), all subjects will commence microneedling treatment for their atrophic acne 
scars. Subjects will then return to the clinic at Week 3 and Week 6 (Visits 2 
and 3, respectively) for follow-up evaluation and additional cycles of 
microneedling treatment. 
At Week 12 (Visit 4), all subjects commence Period II and are randomized to 
Bellafill Treatment (Track A) or to No Treatment (Track B): 
• 
Track A: Consists of three (3) study visits. At Visit 4, subjects 
randomized to the “Bellafill” group will complete visit evaluations and then 
receive treatment with Bellafill for their atrophic acne scars. Subjects 
return for Visit 5A (Month 1 after randomization) for evaluation and follow- 
up, and will receive touch-up injections with Bellafill to achieve optimal 
correction (if necessary). Subjects will then be followed-up at Visits 6A 
and 7A which will occur at Month 3 and Month 6, respectively, after their 
last Bellafill treatment. 
• 
Track B: Consists of one (1) study visit. At Visit 4, subjects randomized  
to the “No Treatment” group will complete visit evaluations and then 
return for follow-up at Visit 5B (approx. Month 3 after randomization). 
Sample Size 
Justification 
This is a pilot study and a formal sample size justification is not provided. It is 
the opinion of the Sponsor that a total of 45 subjects will be sufficient to 
achieve the objectives of the study. 
Statistical 
Methods 
Statistical analyses will be conducted on an ITT basis (i.e., all enrolled 
subjects that have fully passed screening and have received initial 
microneedling treatment will be included in the analyses). Descriptive 
statistics (i.e., mean, standard deviation, etc.) will be provided for all 
continuous variables and frequencies for all categorical variables collected in 
this study. When appropriate, exploratory inferential statistical analyses  will 
be conducted using SAS® software (9.3 or higher). Comparisons between 
treatment groups will be performed using parametric or non-parametric 
testing, as appropriate. The level of significance will be fixed at 0.05. No 
adjustments for multiplicity will be performed.

1. 
Background and Rationale 
Acne scars occur when acne lesions become large enough that the amount of localized 
inflammation overcomes the skin’s ability to heal normally. Dermal collagen is damaged 
and resorbed, leaving defects that are manifested as concavities in the skin surface.. 
There are two general categories of Acne Scars; atrophic or depressed (depressions 
and valleys in the skin with resulting shadowing), and hypertrophic or raised (firm, 
raised papules or nodules on the skin).1 
 
Typically, over 90% of the U.S. population experiences the onset of acne during puberty 
and teen years2 with some women experiencing episodes in the late 20’s through their 
40’s due to hormonal changes.3 A significant percentage will go on to have long term or 
extensive acne scarring,1 90% of which are atrophic acne scars and the remaining 10% 
hypertrophic or some mix of both scars.4 The most commonly used descriptors for 
atrophic scars fall into the following categories.5 
• 
Ice Pick - Deep, narrow sharply marginated scars which resemble how the skin might 
look if injured with an ice pick. 
• 
Rolling or Distensible - More superficial scars with rolled edges that blend more gently 
into surrounding normal skin. 
• 
Boxcar - Sharply marginated depressions with a flat bottom, broader than Ice Pick scars. 
 
1.1 
Incidence and Severity of Acne Scarring 
There is no definitive source of data that clearly shows how many people are afflicted 
with each type of scar in the U.S. However, based on the few published studies found in 
the peer-reviewed literature and following discussions with our clinical advisors, Suneva 
Medical Inc. has developed a general picture of how many people are afflicted. 
 
With regard to scar type, between 60 to 75% of the people with acne scars will have a 
form of rolling or distensible scar as their predominant scar type with roughly 5 to 10% 
having mostly boxcar scars. The remaining 15 to 20% will have ice pick scars as their 
most common scar finding.6 Most individuals with acne scarring will have a mixture of 
two or more types of depressed scars. 
 
Severity is challenging to define due to irregularities in the scar depression and the large 
range in the shape and size of acne scars. In general, studies suggest that mild scarring 
occurs in roughly 60 to 70% of people with scars, moderate scarring occurs in 15 to 25% 
and 5 to 15% of people with scars suffer from severe scarring.7 
 
1.2 
Treatment of Acne Scarring with Bellafill 
Bellafill has been proven to be safe and effective in improving the appearance of 
atrophic acne scars by raising the base of the scar so that it is level with the surrounding 
skin. Based on a pivotal double-blinded, randomized, placebo-controlled study, the FDA 
approved Bellafill for the correction of acne scars in December 2014. 
 
The study required a high threshold for success in which the primary effectiveness 
endpoint was proven superior for subjects treated with Bellafill compared to Control at 6 
months. At 6 months, the response rate for Bellafill was 64% vs. 33% for Control 
(p=0.0005). Bellafill continued to show effectiveness by an unblinded assessment at 12 
months (71%). A responder was defined as a subject in whom ≥50% of treated acne 
scars improved by ≥2 points on the validated 4-point Acne Scar Rating Scale (ASRS).

On the Physician Global Aesthetic Improvement Scale (PGAIS), 84% of subjects were 
rated as improved at 6 months and 98% were improved at 12 months by an unblinded 
assessment. On the Subject Global Aesthetic Improvement Scale (SGAIS), 77% of 
subjects rated their appearance as improved at 6 months and 83% rated their 
appearance as improved at 12 months. 
 
1.3 
Microneedling for the Correction of Acne Scarring 
Microneedling involves puncturing the skin with fine, sterile needles to create small 
wounds in the dermis that is thought to stimulate wound healing resulting in collagen 
production. A mechanical device, consisting of steel microneedles in a wheel, is rolled 
over the surface of the skin in a patterned formation. The microneedles penetrate 
approximately 0.25 to 3.0 millimeters below the skins surface, and each puncture 
creates a channel that triggers production of new collagen and elastin, leading to 
improvement in the appearance of skin texture, firmness, and acne scarring. While 
microneedling is a popular and common procedure practice in many dermatological 
clinics, it has not been approved by the FDA as a treatment for acne scarring. 
 
1.4 
Current Clinical Study 
A therapy that may stimulate collagen production, such as microneedling, is potentially a 
useful adjunct to atrophic acne scar treatment with Bellafill. The current pilot study will 
evaluate the effectiveness and safety of sequential treatment of microneedling followed 
by intra-scar injections with Bellafill. 
 
2. 
Study Objective 
To evaluate the effectiveness and safety of acne scar treatment that sequentially 
employs microneedling followed by Bellafill injections. 
 
3. 
Study Design 
This is an open-label, randomized, multicenter, prospective trial assessing the efficacy 
and safety of microneedling treatment alone vs. microneedling treatment followed by 
treatment with Bellafill for correction of distensible atrophic facial acne scars. 
 
The study is divided into two study Periods. In Period I, subjects will attend a Screening 
visit (Week -4) and undergo the Bellafill skin test. At Visit 1 (Day 0), all subjects will 
commence microneedling treatment for their atrophic acne scars. Subjects will then 
return to the clinic at Week 3 and Week 6 (Visits 2 and 3, respectively) for follow-up 
evaluation and additional cycles of microneedling treatment. 
 
At Week 12 (Visit 4), all subjects commence Period II and are randomized to Bellafill 
Treatment (Track A) or to No Treatment (Track B): 
• 
Track A: Consists of three (3) study visits. At Visit 4, subjects randomized to the 
“Bellafill” group will receive treatment with Bellafill for their atrophic acne scars. 
Subjects return for Visit 5A (Month 1 after randomization) for evaluation and follow- 
up, and will receive touch-up injections with Bellafill to achieve optimal correction (if 
necessary). Subjects will then be followed-up at Visits 6A and 7A which will occur at 
Month 3 and Month 6, respectively, after their last Bellafill treatment. 
• 
Track B: Consists of one (1) study visit. At Visit 4, subjects randomized to the “No 
Treatment” group will complete visit evaluations and then return for follow-up at Visit 
5B (approx. Month 3 after randomization).

Methods 
5.1 
Treatment Area 
On each side of the face, the treatment area is defined inferiorly by the mandibular 
ridge and ramus, medially by the nasolabial fold and a line drawn directly inferior from 
the oral commissure, laterally by the tragus and pinna and superiorly by an imaginary 
line drawn from the lateral canthus to the top of the pinna where it attaches to the face, 
as per the following diagram: 
 
 
5.2 
Study Treatments 
Microneedling Treatment: All eligible scars within the treatment areas on each side of 
the face will receive microneedling treatment. The device will be rolled in a horizontal 
direction with medium pressure. After every roll, the device will be lifted and positioned a 
few millimeters inferior to the previous starting point. Rolling will be repeated until the 
entire skin area has been treated. The device will then be reoriented vertically and  
rolling will be repeated in a vertical direction. See Appendix 2 for additional instructions. 
 
Bellafill Treatment: At Visit 4, all eligible scars within the treatment areas on each side 
of the face will be treated. Bellafill should be injected using a standard tunneling 
technique whereby the filler is injected in a retrograde manner utilizing several passes 
until the scar reaches a desired level of correction. A touch-up treatment is allowed at 
Visit 5B (Month 1 after randomization) if additional treatment is required to achieve 
optimal correction. The total treatment volume of Bellafill used per subject is dependent 
on the number and size of scars treated; however, the maximal volume of Bellafill to be 
injected in a subject is 8.9 ml. 
 
5.3 
Prohibited Treatment/Procedures 
Use of other soft tissue fillers in the face and/or concurrent administration of other 
aesthetic treatments of the face during the study are prohibited (e.g., lasers, implants, 
peels, microdermabrasion, etc.). Other necessary therapies that will not interfere with  
the response to treatment may be provided to the subject at the discretion of the 
Investigator. 
 
Use of the following medications/procedures (concurrent and contraindicated treatments) 
have either restrictions for usage, or are prohibited during the course of the study and 
appropriate wash-out periods noted below must be respected:

Investigational Drugs/Devices 
30 days prior to BL Visit 
 
All treatment/procedures received by the subject within 30 days prior to the baseline visit 
and throughout the treatment period must be recorded in the electronic Case Report 
Form (eCRF) with end dates, if applicable. 
 
If prohibited therapies are administered during the study period, subject participation will 
not automatically be discontinued. The event will be documented by the site staff as a 
protocol deviation, and depending upon the nature of the prohibited therapy and the 
timing relative to the determination of the primary endpoint, the Sponsor may make a 
decision to discontinue the subject. 
 
The decision to administer a prohibited medication/treatment is done with the safety of 
the study subject as the primary consideration. If the permissibility of a specific 
medication/treatment is in question, the ethica CRO Project Manager should be 
contacted before the prohibited medication/treatment is administered. 
 
6. 
Materials 
Bellafill: Commercially available Bellafill and Bellafill Skin Tests will be used (see Skin 
Test IFU and Bellafill IFU in Appendix 3 and 4, respectively). 
Microneedling Dermarollers: Commercially available microneedling dermarollers will 
be provided by Suneva Medical.. Length will be 1.5mm.

6.2 
Supplies and Accountability 
The Investigator or designee will take inventory and acknowledge receipt of all 
shipments of Bellafill and microneedling dermarollers. Bellafill and dermarollers must be 
kept in a locked area with access restricted to designated study personnel. The 
Investigator or designee will also keep accurate records of the volumes of Bellafill 
injected and the number of dermarollers used. Unless other arrangements are confirmed 
in writing, unused syringes/dermarollers will be returned to the Sponsor. 
 
6.3 
Other Study Supplies 
Supplies that are unique to this study will be provided by the Sponsor (e.g., UPTs, etc.). 
The Investigator is responsible for routine supplies related to pre and post-treatment 
care (e.g., alcohol wipes, gauze, etc.). 
 
7. 
Study Methods and Procedures 
7.1 
Informed Consent and Subject Privacy 
The purpose, procedures, risks, benefits, and alternatives to study participation will be 
discussed with each potential subject. Prior to any study-related procedures subjects 
must give their written informed consent. The subject must also give Authorization for 
Use and Release of Health and Research Study Information (HIPAA), authorization to 
take identifying clinical photographs for scientific use and other written documentation 
required by local regulations or the reviewing IRB prior to any study-related procedures. 
 
7.2 
Procedures for Final Study Entry 
A subject is considered “Enrolled” when s/he has signed the IRB-approved informed 
consent form (ICF) and HIPAA authorization in the presence of the Investigator or 
designee. The Investigator (or designee) will collect and record medical and cosmetic 
procedure histories, and females of childbearing potential must have pregnancy test 
results evaluated as negative. All subjects must also have a negative Bellafill skin test. 
The Investigator will assure that each subject meets the washout requirements and 
eligibility criteria before randomization for study treatment. 
 
7.3 
Subject Identification and Numbering 
All subjects who sign an ICF will receive a 3-digit subject number, starting at 001, and 
issued in ascending order. This subject number will be used to identify the subject 
throughout the study. Subjects withdrawn from the study will retain their subject number; 
new subjects will be allotted a new subject number. 
 
7.4 
Randomization and Blinding 
All subjects attending Visit 4 (Week 12) will be randomized to receive “No Treatment” or 
“Bellafill”. A computer-generated randomization schedule will link Randomization 
Numbers to specific treatment assignments at random on a balanced 1:1 basis. Site- 
specific Randomization Lists will be created for each site that contains unique and 
sequentially ascending Randomization Numbers. To randomize a subject  and  
determine treatment allocation, the Investigator or delegate will refer to the lowest 
unused randomization number on the Randomization List. 
 
The next eligible subject will receive the lowest available Randomization Number, 
allowing eligible subjects to be randomized to the study treatment sequence in

accordance  with  the randomization schedule. Randomization Numbers must not be 
omitted or reused. 
 
This is an open-label study and blinding does not apply. 
 
8. 
Efficacy Assessments 
Prior to enrollment of any study subjects, the Investigators will be trained in the use of all 
efficacy assessment scales. Subjects will receive training on how to perform the self- 
assessments during the study. The following assessments will be conducted: 
 
Acne Scar Assessment Scale (ASAS): a validated 5-point static scale assessing physician 
impression of acne scar severity; 
 
Physician Global Aesthetic Improvement Scale (PGAIS): a 5-point dynamic scale assessing 
cosmetic improvement; 
 
Subject Global Aesthetic Improvement Scale (SGAIS): a 5-point dynamic scale assessing 
cosmetic improvement; 
 
Subject QOL Impact Scale: (33 questions): a 33-question survey that allows the subject to 
specifically address how acne scarring has affected his/her emotional and functional status. 
 
See Appendix 1 for additional details regarding the assessments used in this study. 
 
8.1 
Photography 
Facial photography will also be employed in this study. Baseline photographs will be 
used for PGAIS and SGAIS assessments. Canfield Scientific Inc. will provide each site 
with photographic equipment, training and an Instruction Manual prior to the start of the 
study. 
 
9. 
Safety Assessments 
Throughout the study, subjects will be instructed to report any unusual signs or 
symptoms to the Investigator. 
 
The Investigator will solicit and record information about AEs, and concomitant 
medications, therapies and treatments. At each post-treatment visit, phone call, or e- 
mail contact, the Investigator (or designee) will begin by asking the subject a general, 
non-directed question such as ‘How have you been feeling since the last visit?’ Directed 
questioning and examination will then be done as appropriate. All reported AEs will be 
documented in the eCRF.

Instructions for Subjects 
Prior to attending all study visits, subjects must refrain from applying facial cosmetics. 
Makeup may be re-applied after the study visits at the discretion of the Investigator. 
Subjects must avoid prolonged sun exposure to face for 24 hours prior to treatment. 
 
Subjects should avoid strenuous exercise, NSAID products, consumption of alcoholic 
beverages and any exposure to sun or heat for at least 24 hours after treatment to 
reduce the risk of post treatment redness, swelling, and/or itching. Subjects should  
avoid applying sunscreen to the face for the first 24 hours following microneedling 

Microneedling and Bellafill

(v1.0; 11-Sep-2015) 
 
 
treatment. After that period, sunscreen (UVB 30 minimum) should then be diligently 
applied. Subjects will also be advised not to manipulate or massage injected areas. 
 
Subjects will be instructed to contact the Investigator or his/her research staff to report 
any unexpected symptoms or to ask any questions about the study. 
 
10.6 
Unscheduled Visits 
Each time the subject returns to the study site the Investigator will solicit and record 
information about AEs, and concomitant medications, therapies and treatments. An 
interim or unscheduled visit may replace a scheduled visit if it occurs within the 
acceptable time window for a scheduled visit or if the scheduled visit was missed. All 
applicable procedures should be performed. 
 
10.7 
Early Discontinuation/Withdrawal 
It is the right and duty of the Investigator to discontinue a subject’s participation when the 
subject's health or well-being is threatened by continuation in the study. Such subjects 
should be withdrawn from the study and not continued under a modified regimen. In the 
event of premature discontinuation, the Investigator should determine the primary 
reason for discontinuation. A subject who is withdrawn from the study prior to initiation  
of treatment may be replaced. The following are circumstances that may result in the 
subject's discontinuation from the study: 
▪ 
the subject experiences a serious AE rendering them unable to continue study participation; or 
▪ 
the subject is unable to physically or mentally tolerate the test treatment; or 
▪ 
the subject voluntarily withdraws; or 
▪ 
the subject receives a prohibited therapy that could significantly confound the results. 
 
Subjects may voluntarily withdraw from the study at any time without jeopardy to future 
medical care. They may also be administratively withdrawn if they fail to return for follow- 
up. If a subject chooses to withdraw from the study, the subject will be encouraged to 
have a final assessment and undergo the final procedures listed in the protocol. 
 
For any subject who withdraws from the study the date and reason for withdrawal will be 
recorded on the eCRF. If an AE is ongoing at the time of the withdrawal, the Investigator 
will attempt to follow the subject until the AE has resolved or stabilized or until follow-up 
is no longer possible. 
 
10.8 
Lost to Follow-Up 
Significant efforts will be made to encourage all subjects to complete the study. For 
subjects that are lost to follow-up the site will contact the subject’s secondary contact if 
listed in the subject’s medical record or the subject identification log as another means to 
contact the subject. If this is unsuccessful a final certified letter will be sent by the 
Investigator notifying the subject of the need and importance to follow-up. 
 
10.9 
Study Termination 
The Sponsor reserves the right to terminate this study for any reason upon reasonable 
notice to the Investigators. 
 
If conditions arise during the study that indicate that the study or an investigational site 
should be terminated, the Sponsor, Investigator, Monitor, IRB, and/or regulatory 
agencies will discuss the situation and take appropriate action after consultation.

11. 
Adverse Events 
Throughout the course of the study, all AEs will be monitored and reported through the 
AE eCRF. If an AE occurs, the first concern will be the safety of the study subjects. All 
AEs occurring after study device administration will be followed until the event has 
resolved or stabilized or until follow-up is no longer possible. 
 
11.1 
Definitions 
11.1.1 Adverse Events (AEs) 
An AE is defined as any undesirable physical, psychological or behavioral effect 
experienced by a subject during his/her participation in a study, in conjunction with the 
use of the device, whether or not it is considered procedure or product related. AEs may 
include, but are not limited to, subjective or objective symptoms spontaneously offered 
by the subject, solicited via subject interviews, uncovered by review of concomitant 
medications or therapies, and/or observed by the Investigator. The Investigator will 
record the description (sign, symptom, or diagnosis), onset, resolution, seriousness, 
severity, cause and action taken for any event on the AE eCRF. 
 
Disease signs and symptoms that existed prior to the study injections are not considered 
AEs unless the condition recurs after the subject has recovered from the pre-existing 
condition or the condition worsens in intensity or frequency during the study. 
 
Commonly-reported AEs in previous studies include the following local skin changes: 
skin discoloration, increased sensitivity, telangiectasias in implant area, scar, edema, 
erythema, abscess or infection, recurrence of a pre-existing herpes labialis, ulceration, 
erosion or necrosis, itching or burning, pain and/or tenderness, granuloma formation, 
and skin blanching. Additionally, systemic findings reported in prior studies include: drop 
in blood pressure or anaphylactic shock, difficulty breathing, tightness in chest, 
shortness of breath, immune mediated diseases, tingling, numbness, temporary pain in 
various areas of the body, flu-like symptoms, blurred vision, or hypersensitivity to bovine 
collagen. The relevance of these findings to the current Bellafill product is not known. 
 
11.1.2 Common Treatment Responses (CTRs) 
Common Treatment Response (CTRs) following the use with a dermal filler include 
redness, pain, tenderness, firmness, swelling, lumps/bumps, bruising, itching and 
discoloration. CTRs will not be recorded as AEs unless the duration and/or severity are 
in excess of that typically observed following injection of a dermal filler, and are clinically 
significant as determined by the Treating Investigator.

11.1.3 Serious Adverse Events and Unexpected Adverse Device Effects 
A Serious Adverse Event (SAE) is any AE that results in any of the following: 
▪ 
Death 
▪ 
Life-threatening injury or illness – any AE that places the subject, in the view of the reporter, at 
immediate risk of death from the AE as it occurred (It does not include an AE that, had it occurred   
in a more severe form, might have caused death) 
▪ 
Inpatient hospitalization or prolongation of existing hospitalization. However, preplanned or elective 
hospitalizations for pre-existing conditions that have not worsened during the course of the study 
should not be considered SAEs 
▪ 
Persistent or significant disability/incapacity – any AE that results in a substantial disruption of the 
subject’s ability to conduct normal life functions 
▪ 
Important medical events that may jeopardize the subject and may require medical or surgical 
intervention to prevent one of the outcomes listed above 
An Unexpected Adverse Device Effect (UADE) is any device-related AE that meets one 
or more of the following criteria: 
▪ 
Is not identified in nature, severity or frequency in current literature on the product 
▪ 
Is life threatening, even if temporary in nature 
▪ 
Results in permanent impairment of a body function or permanent damage to a body structure 
▪ 
Necessitates medical or surgical intervention to preclude permanent impairment of a body function 
or permanent damage to a body structure 
 
Also considered an UADE is any device malfunction that would be likely to cause or 
contribute to a death or serious injury if the malfunction were to recur. 
 
11.1.4 Severity 
Definitions for classification of severity appear below. For events reported on the AE 
eCRF, the Investigator will determine the severity classification based on these 
definitions, his/her clinical experience in the use of dermal fillers, and/or the subject’s 
description of the event. [Note: A “severe” AE is not the same as a “serious adverse 
event,” which is defined above.] 
▪ 
Mild: Symptoms are barely noticeable or do not make the subject uncomfortable. The AE does not 
influence performance or functioning. Prescription drugs are not ordinarily needed for relief of 
symptom(s). 
▪ 
Moderate: Symptoms are of sufficient severity to make the subject uncomfortable. Performance of   
daily activities is influenced. Tx of symptom(s) with prescription drugs or therapies may be needed. 
▪ 
Severe: Symptoms are of sufficient severity to cause the subject severe discomfort. Performance of 
daily activities is compromised. Tx for symptom(s) with prescription drugs or therapies may be needed. 
 
11.1.5 Relationship to Study Device 
The Investigator will determine relatedness of the subject’s symptom or problem to the 
study device or the injection procedure. 
 
11.2 
Procedures for Reporting Adverse Events 
All AEs should be recorded through the AE eCRF. 
 
11.3 
Procedures for Unmasking of Study Devices 
Not applicable. This is an open-label study.

11.4 
Pregnancy 
A female is considered a Woman of Childbearing Potential (WOCBP) unless she is 
postmenopausal for at least 12 months prior to study treatment administration, without a 
uterus and/or both ovaries, or has been surgically sterile for at least 6 months prior to 
study treatment administration. 
 
In order to participate in the study, sexually active WOCBP must use one of the following 
reliable methods of contraception: hormonal methods or intrauterine device in use ≥90 
days prior to study treatment administration, barrier methods plus spermicide in use ≥14 
days prior to study treatment administration, or vasectomized partner. Non-sexually 
active WOCBP will not be required to practice a reliable method of contraception. These 
subjects may be enrolled at the Investigator’s discretion if they are counseled to remain 
sexually inactive during the study and understand the possible risks in getting pregnant 
during the study. 
 
12. 
Statistics 
12.1 
Sample Size Justification 
Approximately 45 subjects will be enrolled. This is a pilot study and a formal sample size 
justification is not provided for this study. It is the opinion of the Sponsor that a total of  
45 subjects will be sufficient to achieve the objectives of the study. 
 
12.2 
Efficacy Parameter Analysis 
Statistical analyses will be conducted on an intent-to-treat (ITT) basis (i.e., all enrolled 
subjects that have fully passed screening and have received initial microneedling 
treatment will be included in the analyses). Descriptive statistics (i.e., mean, standard 
deviation, etc.) will be provided for all continuous variables and frequencies for all 
categorical variables collected in this study. When appropriate, exploratory inferential 
statistical analyses will be conducted using SAS® software (9.3 or higher). Comparisons 
between treatment groups will be performed using parametric or non-parametric testing, 
as appropriate. The level of significance will be fixed at 0.05. No adjustments for 
multiplicity will be performed. 
 
Summary tables will be used to present population characteristics at Baseline. Data  
from the study questionnaires will be included. For categorical parameters, the number 
and percentage of subjects in each category will be presented. The denominator for 
percentage will be based on the number of subjects appropriate for the purpose of 
analysis. For continuous parameters, descriptive statistics will include n (number of 
subjects), mean, standard deviation, median, and range. No imputation will be used to 
account for missing data. No particular processing for outliers will be performed. Data 
will be presented as reported in the eCRF. 
 
12.3 
Safety Analysis 
Safety analyses will be performed in terms of incidence and severity of adverse events. 
These will be tabulated and a complete listing of all reports of adverse and/or 
unexpected events will be presented. 
 
Concomitant medications will be coded to generic terms. The listing will include study 
treatment date, start and stop date, and whether the drug was taken during study 
treatment.

13.2 
Changes to the Protocol 
Strict adherence to the protocol is necessary to assure validity of the study. The 
Investigator must notify the Sponsor or designee and the reviewing IRB of significant 
deviations from this protocol. Significant deviations to the protocol will be documented 
and maintained as part of the study record. Lost to follow-up, out of window visits or 
assessments missed due to the subject’s non-participation will be documented, but not 
considered significant deviations. 
 
The Investigator must not implement any changes to the protocol without approval by 
the Sponsor and prior review and documented approval from the IRB, except where 
necessary to eliminate immediate hazards to study subjects, or when the changes 
involve only logistical or administrative aspects of the study (e.g., change of telephone 
numbers). 
 
No amendments to the protocol will be implemented without the prior written consent of 
the Sponsor. Should an amendment be necessary, the reviewing IRB and FDA may 
require review and approval of it prior to implementation. 
 
13.3 
Subject Confidentiality and Privacy 
A report of the results of this study may be published or sent to the appropriate health 
authorities in any country in which the study device may ultimately be marketed, but the 
subject’s name will not be disclosed in these documents. The subject's name may be 
disclosed to the Sponsor of the study (Suneva), the CRO (ethica CRO Inc.), the 
governing health authorities (e.g., FDA) if they inspect the study records. Appropriate 
precautions will be taken to maintain confidentiality of medical records and personal 
information.

APPENDIX 2: Microneedling Procedure 
 
Pre-skin Treatment 
• 
Exfoliate the skin with a microderm abrasion brush. 
• 
Wash and rinse the skin, pat dry. 
• 
Sterilize the microneedling device per the manufacturer’s recommendations. 
• 
Provide anesthesia to the skin surface using a topical anesthetic for up to 30 
minutes and/or topical ice pack. 
• 
Remove anesthetic and swab skin with alcohol. 
 
Rolling Technique 
• 
Apply a layer of Regenica Repair Complex to the treatment area before applying 
the needling device. This will help the needles glide smoothly over the surface of 
the skin and prevent additional trauma. 
• 
To achieve a uniform distributed prick density, the best recommended approach 
is to begin rolling in a horizontal direction, and after every roll with medium 
pressure, lift the roller and position it a few millimeters from the previous starting 
point, repeating the rolling movement until the entire skin area has been treated. 
• 
When the treatment is complete, apply another layer of Regenica Repair 
Complex to the region and repeat the process similarly in a vertical direction. 
• 
When rolling, stretch the skin by pulling it with the opposite hand to facilitate 
needle penetration. 
• 
Most important is to lift the roller after each rolling motion, rather than rolling back 
and forth, to prevent a high skin prick density along the same area. Please see 
the diagram below: 
 
 
• 
Perform rolling on the cheeks, and avoid the orbit and lips. 
• 
Rolling diagonally or back-and-forth produce undesirable effects. 
• 
Rolling diagonally is not recommended. This is not the optimal technique 
because the center of the diagonal pattern gets a much greater skin prick density 
than the periphery. A perfectly uniform prick density can only be achieved when 
rolling at straight angles, such as in a horizontal or vertical direction.

• 
Rolling back-and-forth without lifting the roller is also not recommended due to 
extreme prick density distributed over narrow “bands”. If the roller is not lifted 
after each rolling movement, the roller will resist sideway movements because of 
the needles in the skin, producing a “railway effect” as a train on a track. Moving 
back and forth produces the same skin pricks, causing a high prick density or 
larger-diameter of pricks in the skin. 
 
Post-rolling Treatment 
• 
Erythema typically resolves in 12 hours. 
• 
Place an ice pack if needed for pain. 
• 
Moisturize the skin with Vitamin A & C, and/or Aloe Vera afterwards. Moisturize 
with a non-irritating moisturizer. 
• 
Apply sunscreen daily, and only after 24hrs post-microneedling treatment 
 
After-use Disinfection of the Microneedle Instrument 
• 
Sterilize the microneedling device per the manufacturer’s recommendations; use 
an appropriate detergent since alcohols do not dissolve proteins as found in 
blood and skin

APPENDIX 4: Bellafill Instructions for Use 
Bellafill® 
Instructions for Use 
Caution: Federal Law restricts this device to sale by or on the order of a physician or 
licensed practitioner. 
DESCRIPTION 
Bellafill1 is an implant composed of non-resorbable polymethylmethacrylate (PMMA) 
microspheres, 30 to 50 microns in diameter, suspended in a water-based carrier gel 
composed of 3.5% bovine collagen, 92.6% buffered, isotonic water for injection, 0.3% 
lidocaine hydrochloride, 2.7% phosphate buffer, and 0.9% sodium chloride. 
 
INTENDED USE / INDICATIONS 
Bellafill is indicated for the correction of nasolabial folds and moderate to severe, 
atrophic, distensible facial acne scars on the cheek in patients over the age of 21 years. 
 
CONTRAINDICATIONS 
• Bellafill is contraindicated for patients displaying a positive response to the 
required Bellafill Skin Test. Refer to the Bellafill Skin Test Instructions for 
Use for complete instructions for administration and evaluation of the Skin 
Test. 
• Bellafill is contraindicated for patients with severe allergies manifested by a 
history of anaphylaxis or history or presence of multiple severe allergies. 
• Bellafill contains lidocaine and is contraindicated for patients with known 
lidocaine hypersensitivity. 
• Bellafill contains bovine collagen and is contraindicated for patients with a history 
of allergies to any bovine collagen products, including but not limited to injectable 
collagen, collagen implants, hemostatic sponges, and collagen-based sutures, 
because these patients are likely to have hypersensitivity to the bovine collagen in 
Bellafill. 
• Bellafill is contraindicated for patients undergoing or planning to undergo 
desensitization injections to meat products, as these injections can contain bovine 
collagen. 
• Bellafill is contraindicated for patients with bleeding disorders. 
 
• Bellafill is contraindicated for use in lip augmentation and injection into the 
vermilion or the wet mucosa of the lip. 
• Bellafill should not be used in patients with known susceptibility to keloid 
formation or hypertrophic scarring.

WARNINGS 
• The safety of Bellafill when used within 6 months of collagen, botulinum toxin, 
or other wrinkle therapies has not been studied. 
• A Bellafill Skin Test must be administered and evaluated prior to injection of 
Bellafill. Patients demonstrating a positive Skin Test or 2 equivocal Skin Tests 
should not be considered candidates for treatment. Patients demonstrating an anti- 
bovine collagen serum IgG level outside of the normal range at baseline also 
should not be considered candidates for treatment. Refer to the Bellafill Skin Test 
Instructions for Use. 
• Use of Bellafill at specific sites in which an active inflammatory process (skin 
eruptions such as cysts, pimples rashes, or hives) or infection is present should 
be deferred until the inflammatory process has been controlled. 
• Introduction of product into the vasculature may lead to embolization, occlusion of 
the vessels, ischemia, or infarction. Take extra care when injecting soft tissue 
fillers, for example inject the product slowly and apply the least amount of 
pressure necessary. Rare but serious adverse events associated with the 
intravascular injection of soft tissue fillers in the face have been reported and 
include temporary or permanent vision impairment, blindness, cerebral ischemia 
or cerebral hemorrhage, leading to stroke, skin necrosis, and damage to underlying 
facial structures. Immediately stop the injection if a patient exhibits any of the 
following symptoms, including changes in vision, signs of a stroke, blanching of 
the skin, or unusual pain during or shortly after the procedure. Patients should 
receive prompt medical attention and possibly evaluation by an appropriate health 
care practitioner specialist should an intravascular injection occur. 
PRECAUTIONS 
• Bellafill contains non-absorbable PMMA microspheres. Implantation is permanent 
and will not be reversed without physical removal. 
• The safety of Bellafill for use during pregnancy and in breastfeeding females has 
not been established. 
• Bellafill is packaged in a sealed tray containing individual treatment syringes with 
sterile needles for single patient use, packaged in a box. The tip of the syringe is 
sealed with a tamper-evident cover. Do not use if the seal on the tray lid or syringe 
is broken or removed. Do Not Resterilize. 
• The safety of injecting greater amounts than 3.5 cc per treatment site or 8.9 cc 
overall has not been established. 
• The safety and effectiveness of Bellafill for the treatment of non-distensible 
atrophic acne scars has not been established. The use of Bellafill for ice pick or 
sinus tract scars has not been studied. 
• The safety and effectiveness of Bellafill for nasolabial fold wrinkles and cheek 
acne scars have not been established in patients under the age of 21 years. There is 
limited information on the safety of Bellafill in patients less than 36 years of age.

In the pivotal Acne Scar Study of Bellafill, the incidence of injection site reactions 
in subjects less than 36 years old (30 subjects) was similar to the incidence in 
subjects above the age of 36 (113 subjects). The majority of these injection site 
reactions were mild in severity. 
• The safety in patients with known susceptibility to hyperpigmentation, keloid 
formation and hypertrophic scarring has not been studied. Formation of 
hyperpigmentation, keloids or hypertrophic scars may occur after dermal filler 
injections including Bellafill. In the pivotal Acne Scar Study of Bellafill, the 
incidence and severity of adverse events in 34 subjects with Fitzpatrick Skin Types 
V and VI was similar to that reported in 109 patients with Fitzpatrick Skin types I- 
IV and no unique adverse events associated with these patient subgroups were 
observed. 
• As with all transcutaneous procedures, Bellafill injection carries a risk of 
infection. The usual precautions associated with injectable materials should be 
followed. 
• The safety of Bellafill in patients on immunosuppressive therapy has not been 
established. 
• The safety of Bellafill in patients with connective tissue disorder has not been 
established. 
• Bruising or bleeding may occur at Bellafill injection sites. Use of Bellafill in 
patients who have undergone therapy with thrombolytics, anticoagulants, or 
inhibitors of platelet aggregation within 3 weeks preceding treatment has not 
been studied. 
• Patients should minimize exposure of the treated area to excessive sun, UV-lamp 
exposure and extreme cold weather at least until any initial swelling and redness 
has resolved. 
• If laser treatment, chemical peeling or any other procedure based on active dermal 
response is considered after treatment with Bellafill, there is a possible risk of 
eliciting an inflammatory reaction at the implant site. This also applies if Bellafill 
is administered before the skin has healed completely after such a procedure. 
• The use of Bellafill in anatomical spaces other than the dermis for correction of 
nasolabial folds and for acne scars on the cheek has not been studied. Refer to the 
Clinical Studies section for more information on implantation sites that have been 
studied. 
• The use of Bellafill in patients with thin or flaccid skin has not been 
studied and the cosmetic results for these patients are unknown. 
• Long-term safety and effectiveness of Bellafill beyond five years has not been 
established. 
• In order to minimize the risks of potential complications, this product should 
only be used by health care practitioners who have appropriate training, 
experience, and who are knowledgeable about the anatomy at and around the site

of injection. 
• Health care practitioners are encouraged to discuss all potential risks of soft tissue 
injection with their patients prior to treatment and ensure that patients are aware of 
signs and symptoms of potential complications. 
• After use, treatment syringes and needles may be potential biohazards. Handle 
accordingly and dispose of in accordance with accepted medical practice and 
applicable local, state, and federal requirements. 
• Bellafill has an opaque, off-white appearance. In the event that the content of a 
syringe shows signs of separation and/or appears clear (like water), do not use the 
syringe and notify Suneva Medical immediately. In the United States or Canada, 
call toll-free 844-235- 5234. Outside of the United States or Canada call ++1-858- 
550-9999. 
• Bellafill should not be mixed with other products before implantation of the 
device. 
 
ADVERSE EVENTS 
Nasolabial Fold and Acne Scar Indications: 
A total of 1,542 patients have been treated with Bellafill in four U.S. clinical studies. 
Three of the four studies were conducted on 1,399 patients treated with Bellafill in 
support of the indication for the correction of Nasolabial Folds. One of the four studies 
was conducted on 143 patients treated with Bellafill in support of the indication for the 
correction of moderate to severe, atrophic, distensible facial acne scars on the cheek in 
patients over the age of 21 years. 
 
a) 
U.S. Controlled Nasolabial Fold (NLF) Clinical Trials

4 The Control treatment in the study was a commercially available collagen implant (Zyplast®). 
 
No systemic adverse events were reported at an incidence of 1% or greater. One severe 
adverse event (granuloma or enlargement of the implant) and 14 moderate adverse 
events (persistent swelling or redness, lumpiness at injection site more than 1 month 
after injection, blurred vision, flu-like symptoms, abscess, granuloma or enlargement of 
the implant, alopecia areata) were reported for Bellafill subjects. Nine severe adverse 
events (lumpiness at injection site more than 1 month after injection, abscess, infection, 
granuloma or enlargement of the implant, sensitization reactions, increased sensitivity, 
persistent swelling or redness), and 12 moderate adverse events (persistent swelling or 
redness, rash, itching more than 48 hours after injection, sensitization reactions, 
lumpiness at injection site more than 1 month after injection, visibility of the puncture 
area, abscess) were reported for Control subjects. 
Local adverse events reported in Bellafill subjects at an incidence of less than 1% in 
U.S. studies, whether or not they were determined to be related to the implant, were 
sensitization reactions, abscess, visibility of the puncture area, blurred vision, flu-like 
symptoms, recurrence of existing herpes labialis, granuloma or enlargement of the 
implant, acneiform lesions, occasional tenderness, redness and visible capillaries, 
alopecia areata, and dry skin. Systemic adverse events reported at an incidence of less 
than 1% were mild chest congestion and fainting. One subject was diagnosed with 
breast cancer, determined by the investigator not to be related to the implant. 
 
For Control subjects, local adverse events reported at an incidence of less than 1%, 
whether or not they were determined to be related to the implant, were increased 
sensitivity, flu-like symptoms, granuloma or enlargement of the implant, infection, and

(n=5 events), duration was unresolved at 26 weeks. One subject suffered from breast 
cancer unrelated to the implant. 
 
Reported duration of adverse events lasting longer than 2 weeks in Control subjects 
(n=123 subjects): lumpiness at injection site more than 1 month after injection (n=2 
events), duration varied from 13 weeks to unresolved at 26 weeks; persistent swelling or 
redness (n=12 events), duration varied from 7 weeks to unresolved at 26 weeks; 
increased sensitivity (n=1 event), duration was unresolved at 26 weeks; rash and itching 
(n=2 events), duration was unresolved at 26 weeks; sensitization reactions (n=4 events), 
duration varied from 7 weeks to unresolved at 26 weeks; abscess (n=2 events), durations 
were unresolved at 26 weeks; visibility of the puncture site (n=1 event), duration was 
unresolved at 26 weeks; granuloma or enlargement of the implant (n=1 event), duration 
was unresolved at 26 weeks; flu-like symptoms (n=1 event), duration was unresolved at 
26 weeks. One subject died from an accident unrelated to the implant. 
 
Adverse Events Reported Three Months or Longer After Treatment 
Among the 391 subjects treated with Bellafill, adverse events with reported onset dates 
3 months or more after treatment were lumpiness at the injection site (6), rash and 
itching (3), sensitization reaction (2), increased sensitivity (2), persistent swelling and 
redness (1), granuloma or granulomatous inflammation (1), alopecia areata (1), 
visibility of the puncture site (1), and redness and visible capillaries near the area of 
injection (1). 
 
Among the 123 Control subjects, adverse events with reported onset dates 3 months or 
more after treatment were abscess (1), infection (1), lumpiness (1), acneiform reaction 
(1), flu-like symptoms (1), persistent swelling or redness (1), and trauma fatality not 
related to the implant (1). 
 
b) U.S. Controlled Acne Scar Clinical Trial 
The U.S. Acne Scar pivotal study (Study SUN-11-001) involved 147 treated subjects at 
10 centers. At baseline, subjects were randomized to receive Bellafill in the cheeks or 
saline (Control group). At 6 months, all Control subjects were eligible to receive 
treatment with Bellafill.

Of the 147 subjects treated in the study, 143 subjects received a treatment with Bellafill 
at either baseline/Day 0 (Period I) or at Month 6 (Period II, Track B). Therefore the 
safety information reflects the combination of patient outcomes for the initial (n=97) 
and crossover (n=46) Bellafill subjects (i.e., 97 + 46 = 143 total) compared to the 50 
subjects who were initially enrolled in the Control treatment arm. 
1. Subject Diary: 
Subjects were asked to keep diary cards and grade symptoms of erythema, swelling, 
bruising, pain, itching, lumps/bumps and discoloration. Subjects’ scores for the severity of 
these events after initial treatment are presented in Table 2 and durations are provided in 
Table 3,respectively. 
Subjects who observed any signs or symptoms (89.2%), experienced them shortly after 
Bellafill treatment and the majority were mild to moderate in intensity. Subjects 
typically reported these diary card symptoms as resolved in 1-7 days. Similar subject 
diary outcomes were notedfollowing touch-up treatment injections.

* n=143 is based on 97 subjects treated with Bellafill from Study Period I and 46 Period II Control 
subjects that crossed over and were treated with Bellafill 
 
Five serious adverse events (SAEs) were noted during the study; cholecystitis, 
lower-back nerve impingement, recurrence of breast cancer, West Nile meningitis 
and exacerbation of depression. None were deemed related to study treatment. There 
were no deaths during the study. 
 
Adverse events of special interest were followed separately for the study. These 
included hyper and hypopigmentation, hypertrophic scarring or keloid formation and 
the appearance of granulomas. None of these adverse events were reported. 
 
Fourteen (14) Bellafill and no Control subjects experienced treatment-related adverse 
events (TRAEs). Twelve (12) adverse events were mild, one (1) case of injection site 
reaction was moderate in severity, and one (1) injection site bruising was severe in 
intensity. Eleven (11) events resolved and three (3) cases of injection site reaction 
(lumpiness directly after injection) persisted throughout the study. Two (2) of these 
events were deemed by the investigator to be mild and one event was deemed to be of 
moderate severity. All treatment-related adverse events (TRAEs) reported in Bellafill 
subjects by severity and duration are presented in Table 5 and 6, respectively.

c) US 5-Year Post Approval Study (PAS001-Study P521-01) 
In agreement with FDA, Suneva Medical conducted a 5-year prospective study of 
Bellafill as an injectable implant for the correction of nasolabial folds (NLF). 
The primary objectives were to determine the incidence of granuloma formation and the 
incidence of adverse events at each follow-up period. The secondary objective was to 
determine the subject’s assessment of satisfaction using a five-point scale at each follow- 
up visit over the 5 year time period. 
 
This was a multi-center (23 sites), open-label study in which one thousand and eight 
(1008) subjects were followed for a five-year period after their completion of NLF 
correction with Bellafill. Treatments were administered according to the approved 
labeling for the Bellafill NLF indication. Subjects underwent up to three injection 
sessions over 6 weeks as needed to obtain the best possible correction.

Follow-up for AEs and satisfaction data was completed by mail or telephone 
questionnaire survey at 6, 12, and 18 months, and 2, 3 and 4 years post-treatment. 
Subjects were seen and examined in person at the 5 year post-treatment visit. If the 
questionnaire responses submitted at any timepoint indicated a potential adverse event 
in the treatment area and/or the face, the subjects were asked to return to the study site 
for evaluation. 
 
Adverse events reported by subjects were confirmed and adjudicated by the 
investigators. Any event that an Investigator thought might potentially be a 
granulomatous lesion was biopsied and sent to an independent pathology lab for 
evaluation and diagnosis. 
 
Primary Endpoints (safety): (1) Incidence of clinically identified and histologically 
confirmed granulomas tabulated by event and by subject; (2) incidence of serious 
unanticipated AEs stratified by severity and relation to treatment and tabulated by event 
and by subject; (3) incidence of anticipated AEs categorized as granulomas, serious 
unanticipated AEs, and AEs tabulated by event and within each study period. 
Results confirmed both the short and long term (5 year) safety of Bellafill, as no device- 
related serious adverse events (SAEs) or unanticipated AEs were noted and the general 
adverse event profile was similar to prior NLF studies. 
 
A total of 887 AEs were reported among 416 of the 1008 treated subjects. A total of 101 
SAEs were reported among 75 treated subjects; none of these SAEs were considered 
device-related, and all were unanticipated. Of these 101 serious adverse events the 
majority were moderate to severe (86). The most commonly reported SAEs were “other 
systemic complications (46)” and “other local complications (43)” non device–related 
SAEs. 
 
A total of 177 device-related AEs among 118 treated subjects were observed. Of the 
177 treatment-related adverse events, the majority (131, 74%) were mild in severity. 
Forty-two (24%) of these related events were moderate in severity and four (2.0%) 
were considered severe. The most commonly reported device related adverse events 
were “lumpiness at the injection site” (29%) followed by “redness” (11%) see 
Table 7. 
 
The duration of device related adverse events is provided in Table 8. Most of the 
device related adverse events were resolved during the study period. Thirty two related 
adverse events (18%) were deemed to be ongoing. The number of device related 
adverse events observed within the first month, 1-6 months, and beyond 6 months were 
comparable. The most common ongoing device related event was “lumpiness at the 
injection site” (12, 7%).

Granulomas were encountered in 17 of 1008 subjects (1.69%). All of these cases were 
considered at least possibly related to the treatment; however, none were identified as 
SAEs. The majority of these cases were assessed as mild or moderate in severity by the 
investigator (15/17) and typically responded to medical therapy. Eight of seventeen 
(8/17) cases resolved during the course of the study, 8/17 showed improvement by study 
exit and were still being treated at the time of study exit, and a single lesion remaining 
stable at study exit, although improved from the time of diagnosis (See Table 9).

POST-MARKETING SURVEILLANCE 
 
Since product approval for the correction of nasolabial folds, the adverse events 
received via Bellafill post-marketing surveillance in on-label or off-label settings have 
been infrequent. 
Those events that were reported in five or more instances include (in order of 
decreasing frequency reported) lumps/bumps, swelling, nodules, bruising, granuloma, 
redness, and reported allergic reactions. Time to onset for these events ranged from

(v1.0; 11-Sep-2015) 
 
 
immediate to three-and- a-half years post-injection. The majority of the events (when 
severity was reported) were mild in severity and no events were characterized as 
serious. Outcomes for these events ranged from resolution to ongoing at the time of last 
contact. The treatments for these events included massage, ice packs, warm compresses, 
antibiotics, antihistamines, various energy treatments, oral and intralesional steroids, 
and device excision. 
 
Adverse events possibly related to intravascular injection have been reported. 
Symptoms ranged from possible skin discoloration to bumps to skin necrosis. Time of 
onset (when known) ranged from the day of injection to 3 days post treatment. The 
majority of the intravascular injection events were mild in severity and no events were 
reported as serious. Treatments included nitroglycerin paste, aspirin, and warm 
compresses. These events resolved or were resolving within one month after onset. 
 
A single case of blindness was reported as a Medical Device Report (MDR) after 
Bellafill injection. The patient was injected in the right canthal area (periorbital), and 
experienced immediate onset of loss of vision in the right eye. Treatments included 
IV saline, direct pressure release in the anterior chamber of the eye, and treatment in 
a hyperbaric oxygen chamber. The patient’s vision did not return. In this patient 
case, periorbital injection of Bellafill was outside the recommended Indications for 
Use (see Warnings section). 
 
Adverse reactions should be reported to Suneva Medical, Inc., at 1-858-550-9999. 
 
U.S. CLINICAL TRIALS 
a) CONTROLLED NASOLABIAL FOLD TRIAL 
A prospective, multi-center, double-masked, randomized trial compared Bellafill and a 
commercially available collagen implant for the treatment of soft tissue defects of the 
face. A total of 251 (i.e., 128 Bellafill and 123 Control) subjects were enrolled and the 
nasolabial folds of 212 (i.e., 108 Bellafill and 104 Control) subjects were treated. 
The primary effectiveness endpoint was a comparison of the cosmetic correction 
provided by Bellafill and Control treatments at the end of a 6-month period after 
injection, evaluated by means of a validated facial-fold assessment scale (FFA Scale) 
using standardized photographs as reference. The numerical values for the FFA Scale 
were: zero – no folds; one – folds just perceptible (i.e., ~0.1 mm); two – shallow folds 
with some defined edges (i.e., ~0.2 mm); three – moderately deep folds with some well- 
defined edges (i.e., ~0.5 mm); four – deep folds with most edges well defined and some 
redundant folds (i.e., ~1.0 mm) and five – very deep folds with most edges well defined 
and some redundant folds (i.e., ~2.0 mm). Comparisons to the reference photos were 
made at pre-treatment and at each follow-up visit. Safety was evaluated by comparing 
the incidence and severity of clinical events during and for 12 months after treatment 
completion.

by a Control subject, was Persian. 
2Subjects in the Bellafill treated group had a higher baseline fold severity than those in the 
Control group. The difference was statistically significant (p=0.039). 
 
Results 
The mean improvement in nasolabial fold wrinkle severity, as characterized by the 
masked observers, for subjects from before treatment to 6 months after completion of 
treatment was: Bellafill – 0.77 points, and Control – 0.00 points. The difference was 
statistically significant (p 
= < 0.001). 
 
Additional Analysis 
At 1 month after treatment, 0.75 points (Bellafill) and 0.74 points (Control) differences 
from baseline for nasolabial fold wrinkle severity were recorded. At 3 months after 
treatment, differences of 0.81 points (Bellafill) and 0.15 points (Control) were 
determined for nasolabial fold. At 12 months after treatment, a nasolabial wrinkle 
severity difference of 0.98 points (compared to baseline) was recorded for Bellafill 
subjects. No assessment of nasolabial fold wrinkle severity was performed at 12 months 
after treatment for Control subjects. 
The number of treatment sessions and volumes administered in nasolabial folds over the 
course of the study are displayed in Table 11 and 12, respectively.

b) OPEN-LABEL NASOLABIAL-FOLD STUDY 
This open-label, single-arm, multi-center study assessed the safety of Bellafill injections 
for the correction of soft-tissue defects of the face. 157 subjects were enrolled and 
monitored at 3, 6, and 12 months post-treatment. Approximately 80% (126/157) of 
subjects completed the 1-year study. The safety data collected in this study were included 
in Table 1. 
 
c) CONTROLLED ACNE SCAR STUDY 
A prospective, multi-center, randomized, double-blind, controlled trial assessing the 
effectiveness and safety of Bellafill for the correction of facial atrophic acne scars was 
conducted. A total of 147 (97 Bellafill and 50 Saline Control) subjects were enrolled 
and treated in the controlled phase of the study. 
The primary effectiveness endpoint was a responder analysis in which the criteria for 
success at 6 months was defined as 50% or more of treated scars improving by 2 or 
more points, based on the blinded-investigator assessment utilizing the validated 4 point 
Acne Scar Rating Scale (ASRS). The objective was to show that Bellafill was superior 
to Control in treating acne scars. The ASRS (Table 13) is a four-point, static scale, 
ranging from minimal to severe, that relies on the depth of individual scars for severity 
assessment.

The number and severity of scars per subject are shown in Table 15. There were no 
differences between treatment groups regarding the number of qualifying scars or their 
severity. The median number of scars to be treated for each subject was 8.0 in each group 
(mean value shown below) with a median Acne Scar Rating Scale (ASRS) severity of 3.2 
in each group.

Results 
The primary effectiveness endpoint was analyzed as a responder analysis, in which the 
criterion for success was defined as 50% or more of treated scars on a patient improved 
by two or more points on the ASRS at the 6 month visit (as evaluated by a live, blinded 
evaluator). The observed success rate at 6 months in the Bellafill group was 56/87 
(64%) and significantly higher (p=0.0005) than in the Control group 15/46 (33%).

Bellafill was found to be effective in all Fitzpatrick skin types, and for male subjects as 
well as female subjects. 
 
A secondary effectiveness endpoint was a responder analysis (i.e., success was defined 
as 50% or more of treated scars on a patient improved by two or more points) 
determined via ASRS at each time point by a live, blinded evaluator. The observed 
success rates in unblinded assessments at 9 and 12 months for the Bellafill group were 
48/78 (61.5%) and 58/82 (70.7%). See Figure 1.

Additional Effectiveness Analyses 
In addition to assessing patient responder rates, the response rate of individual scars was 
also compared. In this analysis where scars with a greater-than or equal-to two-point 
improvement on the ASRS over baseline were considered responders, 442/789 (56.0%) 
of scars in the Bellafill group and 118/397 (29.7%) of scars in the Control group were 
judged as successes. 
Bellafill injections were superior to Control treatment at all study visits after the Week 4 
touch- up injection. 
Independent, masked review of photographs (IPR) from the Month 6 visit by three 
board- certified physicians revealed a higher ASRS response rate for Bellafill than 
Control subjects, but these rates were lower than those determined by live, blinded 
evaluators.

Subjects blinded to the treatment rated the overall degree of improvement in their treated 
scars using a five-point, non-validated Subject Global Aesthetic Improvement Scale 
(SGAIS) where 5 was “much improved”, 3 was “no change” and 1 was “much worse.” 
Seventy-seven percent (77.0%) of subjects (67/87) treated with Bellafill and forty-one 
percent (41.3%) treated with Control (19/46) reported improvement in their global 
appearance at 6 months after their injection. Subjects who were treated with Bellafill 
continued to report improvement in their global appearance in an unblinded assessment 
at Month 9 (84.6%) 66/78 and at Month 12 (83.1%) 69/83. 
 
BENEFIT / RISK CONCLUSIONS 
The benefits as determined by the improvements seen on the Acne Scar Rating Scale 
and patient satisfaction scale as well as the risks as assessed from short-term adverse 
outcomes seen after injection and rare late adverse events, are sufficiently well 
understood for patients to make informed decisions about device use. 
 
d.) US 5-Year Post Approval Study (PAS001-Study P521-01) 
Total number of Enrolled Study Sites and Subjects, Follow-up Rate: This was an 
open label uncontrolled study in which 23 sites enrolled 1008 subjects with a 
completion rate of 87% at the end of the 5-year study. The primary objectives were to 
determine the incidence of granuloma formation and the incidence of adverse events at 
each follow-up period. The secondary objective was to determine the subject’s 
assessment of satisfaction using a five-point scale at each follow-up visit over the 5 year 
time period.” 
 
The Effectiveness Endpoint was based on: Subject satisfaction using a 5-point scale, 
where 1 = very satisfied, 2 = satisfied, 3 = somewhat satisfied, 4 = dissatisfied and 5 = 
very dissatisfied. 
 
Study Visits and Length of Follow-up: After treatment, subsequent follow-up was 
conducted by mail or telephone questionnaire survey at 6, 12, and 18 months, and 2, 3 
and 4 years post- treatment. Subjects were seen and examined in person at 5 years post- 
treatment visit. 
 
The study population is shown in Table 16 below. The population enrolled is typical of 
individuals seeking correction of NLFs in current clinical practice.

1 Subjects were permitted to report more than one race, therefore the total number of subjects 
exceeds the number of subjects in the study (N=1008).

Argentinian, Black / Korean, Hispanic or Latino, Hispanic- Portuguese, Indian, Iranian, Latino, 
Mexican, Mexican American, Portuguese, Puerto Rican, Spanish (Spain) 
 
3. Results: Effectiveness – Subject Satisfaction 
Based on subject assessment of satisfaction (using an unbalanced and unvalidated 
scale), patients reported satisfaction with Bellafill treatment throughout the entire study. 
One year after the final treatment the mean subject satisfaction rating was 1.80 (where 
1= very satisfied and 2= satisfied). At 5 years after the last treatment 83% of subjects 
were either very satisfied or satisfied with their treatment outcome and the mean 
Satisfaction score was 1.70. 
 
e) COLLAGEN IMMUNOREACTIVITY 
All subjects were required to have a Skin Test prior to being considered for injection 
with Bellafill. 
Results of the Skin Tests – In the randomized NLF study, there were no positive Skin 
Tests in the 128 patients first randomized to receive Bellafill treatment or the 106 
Control subjects who elected to receive Bellafill injections in the crossover cohort. Of 
the 141 subjects who received the collagen Control Skin Test, 6 had a positive Skin Test 
and were excluded from the study. 
Serum IgG – In the randomized NLF study, 4 Bellafill and 2 Control subjects were not 
treated because they displayed abnormal baseline serum IgG levels against collagen 
during screening. One subject in the Bellafill group transitioned from a normal IgG 
level before administration of the Skin Test to a value above the normal range at 1 
month after treatment. This subject’s IgG levels returned to the normal range by 3 
months after treatment.

Acne Scar Study: 175 subjects received the Bellafill Skin Test. Three subjects (1.7%) 
demonstrated a positive Skin Test, and were excluded. 
5- Year Post Approval Study: 1211 subjects received the Bellafill Skin Test. Eight 
subjects (0.7%) demonstrated a positive Skin Test, and were excluded. 
 
INDIVIDUALIZATION OF TREATMENT 
A complete medical history should be obtained to determine whether the patient is an 
appropriate candidate for treatment with Bellafill. 
 
HOW SUPPLIED 
Bellafill is an aseptic product that is required to pass a USP sterility test before release. 
It is supplied in a sealed tray containing individual treatment syringes with sterile 
needles for single patient use, packaged in a box. Each syringe contains: 20% 
polymethylmethacrylate microspheres and 80% bovine collagen solution containing 
3.5% bovine collagen, 2.7% phosphate buffer, 0.9% sodium chloride, 0.3% lidocaine 
hydrochloride, and 92.6% water for injection. 
The tray lid and tip of each individual syringe is sealed with a tamper evident cover. Do 
not use if the tamper evidence cover is broken or removed. Do Not Sterilize. 
 
IMMUNOGENICITY TEST PROCEDURE 
Four (4) weeks prior to treatment, patients will be given a 0.1cc test injection of Bellafill 
skin test material intradermally in the volar forearm, to determine a patient's sensitivity 
to the treatment material. For a complete discussion of the Bellafill Skin Test, refer to 
the Instructions for Use supplied with test syringes. 
 
Test Interpretation 
The patient should observe the test site daily during the 4-week test period and notify 
the physician immediately if any effects indicative of a positive or equivocal response 
are observed or if systemic effects are experienced. A Bellafill Skin Test Results Card 
should be provided to the patient at the time of the Skin Test to help the patient assess 
the test site. 
 
Positive Response 
A positive response consists of erythema of any degree, induration, tenderness, and 
swelling, with or without pruritus, which can appear immediately following 
implantation and persists for more than 24 hours or appears more than 24 hours 
following implantation for any length of time. 
 
Equivocal Response 
An equivocal response is one in which there is no localized skin reaction, but the patient 
does elicit a possible systemic reaction such as a rash, arthralgia (aching joints), or 
myalgia (aching muscles) that occurs at any time during the 4-week observation period. 
If an equivocal response is observed, a second injection in the opposite arm is required, 
with observation for an additional 4 weeks. Patients demonstrating a positive or 
equivocal response in this second test should not be treated.

DIRECTIONS FOR USE 
Bellafill is indicated for the correction of nasolabial folds and moderate to severe, 
atrophic, distensible facial acne scars on the cheek in patients over the age of 21 years. 
1. Prior to treatment with Bellafill, the results of the Skin Test must be carefully 
evaluated; the patient must not have a response to the required Bellafill Skin Test. 
For a complete discussion of the Bellafill Skin Test, refer to the Instructions for 
Use supplied with Skin Test syringes. 
2. Prior to treatment with Bellafill, the patient should be fully informed of the 
indications, contraindications, warnings, precautions, treatment responses, 
adverse reactions, and method of administration. Patients also should be 
advised that supplemental touch-up treatments might be required to achieve 
correction. 
3. A complete medical history should be obtained to determine whether the 
patient is an appropriate candidate for treatment with Bellafill. 
4. The patient’s soft-tissue contour deficiencies should be characterized with 
regard to etiology, distensibility, and depth of lesion. Pretreatment photographs 
are recommended. 
5. Scars selected for treatment should be atrophic distensible scars. 
6. The Bellafill syringe must be brought to room temperature before injection. 
7. After ensuring that the patient has thoroughly washed the treatment area with 
soap and water, the area should be cleaned with alcohol or other antiseptic. 
8. Bellafill is implanted through a 26 G needle. Best results with Bellafill are achieved 
in defects requiring deep dermal implant placement and not into the subcutaneous 
fat. The rate and degree of correction in the implanted area varies with patient, 
treatment site, and plane of implant placement. Correction should be conservative 
during initial treatment. 
9. Before injecting the patient, depress the syringe plunger until Bellafill is visible at 
the tip of the needle. 
10. The best cosmetic result for NLFs can be achieved by a standard linear threading 
technique moving the needle back and forth beneath the skin being treated and 
maintaining constant injection pressure while withdrawing the needle (retrograde 
liner threading). Injection for acne scar can use both the retrograde linear threading 
and serial puncture techniques. The injection pressure is correct if the implant 
flows slowly and evenly, without great exertion. This technique forms a support 
structure beneath the skin to prevent further wrinkling and/or to maintain the scar 
correction. 
11. If needles become occluded or dull during a treatment session, 
replacement may be necessary. 
12. Gentle massage of the skin with the fingertips may facilitate even distribution of 
Bellafill immediately after implant placement.

13. The area and the borders of Bellafill injection should be recorded on an illustration 
of a face for later comparison. 
14. The physician should instruct the patient to report to him or her any evidence of 
adverse texture change in the surrounding treatment site. Other problems 
possibly associated with the use of Bellafill should be promptly brought to the 
attention of the physician. 
15. The syringe and any unused material should be discarded after a single treatment 
visit. 
16. Correction should be limited to no more than 100% of the skin defect during 
treatment. One or two touch-up implantations at intervals of at least 2 weeks may 
be required to achieve the desired effect. The interval at which touch-up 
implantations are needed depends on the nature of the defect, the amount of implant 
injected, the site of placement, and the dynamics at the corrected sites.
