1 SYNOPSIS 
Study title 
Radiesse® Post Approval Safety Study - Radiological Evaluation of Implantation in the 
Hands 
Study phase 
Device Post-Market 
Study Product 
Radiesse Injectable Implant 
Indication 
Hand augmentation to correct volume loss in the dorsum of the hand  
Primary study objective 
The objective of this study is to provide a preliminary assessment of the radiographic 
appearance of Radiesse material that has been injected into the dorsum of the hands.  The 
assessment will be with standard, plain radiography (X-rays).  The hypothesis is that the 
radiographic appearance of Radiesse in the hands does not obscure the bones of the hands 
as seen on plain X-rays of the hand. 
Primary study endpoint 
The primary endpoint is the safety assessment of the incidence of obscuration of the 
bones of the hand at 1-, 6-, 12-, and 24-months following injection of Radiesse in the 
dorsum of the hand. 
Study population, diagnosis, and main criteria for in- and exclusion 
The study will enroll 20 qualifying subjects at least 22 years of age with moderate to very 
severe volume loss in the dorsum of their hands based on the Merz Hand Grading Scale 
(MHGS1, Figure 1), 10 with moderate to severe volume loss (MHGS grades 2 and 3) and 
10 with very severe volume loss (MHGS grade 4).  Key exclusion criteria include hands 
with previous fat injections, hand deformities, or surgery in the dorsum of the hands, and 
any medical condition with the potential to interfere with the study or increase the risk of 
adverse events (AEs).  See Section 7 for the full list of inclusion and exclusion criteria.

4 INTRODUCTION 
4.1 
Study background 
This clinical study is a post approval study (PAS) being conducted to satisfy a condition 
of the June 4, 2015, PMA-S (P050052/S049) approval of Radiesse injectable implant 
indicated for hand augmentation to correct volume loss in the dorsum of the hand.  The 
purpose of the PAS is to provide a radiological evaluation of hands after implantation 
with Radiesse.  X-rays of the hands were not taken in the pre-market study (Merz 
protocol #P110607) of 113 subjects. 
4.2 
Study rationale 
Radiesse dermal filler is radiopaque and shows no overt radiographic safety concerns in a 
study of 58 patients after facial implantation, with Radiesse not always visible on plain 
X-rays2.  This PAS study will evaluate if there are concerns after Radiesse implantation 
in the dorsum of hands, specifically if implantation interferes with radiological 
assessment by obscuring the bones of the hand. 
For a greater understanding of potential radiographic concerns, this study will assess the 
effect of Radiesse volume over time.  Enrolled subjects will have baseline dorsal hand 
grades ranging from moderate (MHGS grade 2) to very severe volume loss (MHGS grade 
4).  The volume of Radiesse required to correct the baseline hand condition will be lower 
for moderate volume loss and higher for very severe volume loss.  Baseline X-rays will 
be taken before, and 1-and 6-months after treatment on all subjects.  If bones are not 
visible on the 6-month X-rays, another set of X-rays will be taken at 12-months.  In the 
clinical practice of dermal filler implantation, patients seek repeat treatments to sustain 
the aesthetic benefits.  In this study, there will be the opportunity for each subject to have 
up to 3 repeat treatments during participation in the 24-month study.  To evaluate 
potential radiographic safety concerns of cumulative volumes of repeat treatments over 
time, X-rays of the hands will be taken at 24-months on all subjects who receive 4 
treatments in this study: initial treatment plus 3 repeat treatments. 
4.3 
Risk-benefit assessment 
Potential risks associated with the injection of Radiesse into the dorsum of the hand to 
restore volume loss are similar to injections performed with any other commercially 
available cosmetic dermal filler, such as bruising, swelling and redness.  A potential risk 
of participation in this study would be the potential obscuring of hand bones in X-ray 
images that might be taken in the event of a hand injury.  For complete safety and risk 
information, see the Instructions For Use (IFU, Appendix A).

Lidocaine is approved as a local and regional anesthetic and will be mixed in-office with 
Radiesse. Potential side effects associated with lidocaine are a risk of participating in this 
study and include lightheadedness, nervousness, apprehension, euphoria, confusion, 
dizziness, drowsiness, ringing noise in the ears, blurred or double vision, vomiting, 
sensations of heat, cold or numbness, twitching, tremors, convulsions, unconsciousness, 
respiratory depression and arrest, slow heartbeat, hypotension, and cardiovascular 
collapse, which may lead to cardiac arrest.  However, these side effects are unlikely to 
occur at the low doses of lidocaine being used in this investigation.  Lidocaine is 
beneficial in terms of pain reduction during and after the study procedure. 
Potential risks associated with X-ray imaging of the hand are those that are associated 
with the use of X-ray imaging, that include development of cancer later in life and tissue 
effects such as skin reddening and hair loss.  The levels of ionizing radiation and duration 
of exposure to be used in this study are low and are not expected to result in tissue 
effects. 
A potential benefit of participating in this study is to have correction of volume loss and 
reduction of the prominence of veins and tendons in the dorsum of 1 or both hands.  
Additional potential benefits of improving the appearance of the hands could include 
enhanced emotional well-being with improved satisfaction with the appearance of the 
hands, or the perception of having a more youthful appearance.

5 STUDY OBJ ECTIVES AND ENDPOINTS 
5.1 Objectives 
The primary objective of the study is to provide a preliminary assessment of the 
radiographic appearance of Radiesse material that has been injected into the dorsum of 
the hands.  The assessment will be with X-rays, as interpreted by a remote imaging core 
lab.  Based on preliminary radiographic data of Radiesse implantation in the face3, it is 
expected that Radiesse injection(s) in the hands will not obscure the bones as seen on 
plain X-rays of the hand; however, this is not being evaluated with hypothesis testing. 
Other objectives of the study include evaluating the effectiveness of Radiesse 
implantation for very severe volume loss in the dorsum of the hands, the rate of 
device/injection-related severe adverse events, the safety of multiple retreatments with 
Radiesse in the dorsum of the hands.  
 
 
 
 
 
5.2 Endpoints 
The primary safety endpoint of the study is the incidence of obscuration of the bones of 
the hand at 1, 6, 12 and 24 months.  
The secondary endpoints of the study are:  
• 
MHGS at 1- and 6-months after initial treatment 
• MHGS at 1- and 6-months follow retreatment for those receiving retreatment 
• GAIS at 1- and 6-months after initial treatment 
• GAIS at 1- and 6-months follow retreatment for those receiving retreatment 
• MHQ at baseline, study exit, and other collected time points 
• The rate of device/injection-related severe AEs at 1- and 6-months

6 INVESTIGATIONAL PLAN 
6.1 
Overall study design 
This is a prospective, open-label 2 year PAS evaluating radiographic appearance of 
Radiesse implantation in the dorsum of the hands in 20 subjects (40 hands).  All subjects 
will be new subjects who did not participate in the pre-market Radiesse hand treatment 
study (Merz #P110607).  Subjects will be consented at 1 investigational site in the United 
States. 
Multiple assessments will be performed at study visits.  Some of the main assessments 
include: 
• X-rays – X-rays will be taken at a licensed radiographic imaging center and 
transmitted to the imaging core lab to be assessed by two blinded, licensed 
radiologists 
• MHGS (Figure 1)– a single blinded site evaluator will grade the hands using the 
MHGS  
 
 
 
 
• MHQ – subjects will self-report assessment of the effect(s) of Radiesse injection 
on hand function using the MHQ 
• GAIS (Table 1) – subjects will rate the aesthetically pleasing aspect of the 
Radiesse hand treatment using the GAIS 
• AE Subject Diary – subjects use this to collect any AEs for 30 days post injection 
• Photographs – at baseline and exit from the study, and during the study to 
document a serious or medically concerning adverse event in the hands. 
6.1.1 Study visits 
Subjects will be required to present for a total of up to 15 visits and 4 follow up phone 
calls.  Of these visits, 7 to 10 are in-office investigational site visits and an additional 3 to 
5 are X-ray visits at a licensed radiology center, and 1 to 4 are follow-up phone calls 
during their 24-month study participation. 
If a subject only receives the initial treatment at enrollment, there will be a total of 7 in-
office clinic visits, 3 x-ray visits and 1 follow-up phone call.  For each of the 3 optional 
repeat treatments received, there will be an additional follow-up phone call (72 hours post 
injection).  The fourth x-ray visit will only be required at Month 12 if no bones are visible

at the 6 month x-ray and the fifth x-ray visit will only be conducted if a subject receives 
four total treatments of Radiesse in this PAS study. 
Following consent and enrollment at the site, subjects will have X-rays taken of their 
hands at the radiology imaging center.  Each digital radiographic image taken in the study 
will be assessed by 2 independent blinded, licensed radiologists at the radiology core lab.  
After X-rays, all subjects will return to the study clinic to receive Radiesse treatment. 
At 1-month, all subjects will have X-rays of their hands taken and will be assessed by the 
treating investigator for AEs.   
At 6-months after enrollment, all subjects will have X-rays of their hands taken prior to 
receiving a repeat Radiesse treatment, if Radiesse retreatment is agreed upon by treating 
investigator and subject.   
Subjects will have X-rays of their hands at 12-months only if bones of the hands were 
reported to be obscured by Radiesse by at least 1 radiologist on the 6-month X-rays, and 
will be assessed by the treating investigator for AEs.  Subjects will receive repeat 
Radiesse treatments at 12- and 18-month follow-up visits if Radiesse retreatment is 
agreed upon by treating investigator and subject.  If X-rays of the hands are required at 
12 months, they will be taken prior to Radiesse retreatment.   
Subjects will have X-rays at 24-months only if they receive 4 Radiesse treatments in the 
study; at enrollment, 6-, 12-, and 18-months after enrollment.   
An additional 1-month follow-up visit and 72-hour follow-up phone call will be 
scheduled after each repeat treatment received at the 6-, 12-, and 18-month visits which 
would be at 7-, 13-, and 19-months, respectively. 
6.1.2 
End of study 
The end of study will be defined as completion of all study visits by all enrolled subjects 
during the 24-month participation period.  If an unforeseen device-related serious adverse 
event (SAE) or unanticipated serious adverse device effect (USADE) occurs, the end of 
the study will be prolonged until clinical resolution of the event. 
The study or parts of the study may be discontinued by Merz North America, Inc. (Merz) 
or at the recommendation of an investigator after consultation with Merz at any time.  
This may be based on a significant number of AEs of a similar nature that warrant such 
action or at the request of Merz.

7 STUDY POPULATION 
The study will enroll adults at least 22 years of age.  There will be 2 study groups, with 
10 subjects enrolled into each group.  Group A subjects will be required to present with 
MHGS grade 4 hands at baseline.  Grade 4 hands are defined as, in the dorsal hand: very 
severe loss of fatty tissue and marked visibility of veins and tendons.  Group B subjects 
will be required to present with MHGS grade 2 or 3 hands at baseline.  Grade 2 and 3 
hands are defined as, in the dorsal hand:  moderate to severe loss of fatty tissue and mild 
to moderate visibility of veins and tendons as determined by the investigator based on the 
MHGS.  Group A subjects will provide radiographic assessment images of MHGS grade 
4 hands, which might receive higher injection volumes than hands of Group B subjects.  
Every effort will be made to have all enrolled subjects complete the study.  If subjects are 
withdrawn or lost to follow during the study, they will not be replaced.

8 TREATMENTS 
8.1 
Investigational product(s)  
8.1.1 
Description of investigational product(s) 
Radiesse injectable implant is an opaque, sterile, non-pyrogenic, semi-solid, cohesive 
implant.  The principle component is synthetic calcium hydroxylapatite suspended in a 
gel carrier that consists primarily of water (sterile water for injection USP), glycerin 
(USP), sodium carboxymethylcellulose (USP).  Radiesse injectable implant (1.5cc 
syringe unit) has a CaHA particle size range of 25-45 microns and should be injected 
with a 25 gauge Outer Diameter to 27 gauge Inner Diameter needle. The same size needle 
should be utilized throughout the trial for an individual subject. 
8.1.2 
Disposition of investigational product(s)  
Radiesse has been FDA approved for injection into the face since 2006 (PMA P050037 
and PMA P005052), and was approved for hand augmentation to correct volume loss in 
the dorsum of the hand in 2015 (PMA P050052/S049, see IFU Appendix A). This same 
Radiesse formulation will be used in this study for injection, as approved in the indication 
for hand augmentation to correct volume loss in the dorsum of the hand.  Radiesse will be 
mixed with 2% lidocaine HCl prior to injection – an approved use of Radiesse. 
8.2 
Treatment administration 
8.2.1 
Randomization Procedures 
The study is not a randomized trial, and there are no randomization procedures. 
8.2.2 
Treatment method 
Prior to injection, Radiesse will be mixed with 0.26cc of 2% Lidocaine HCl.  Volume 
injected as well as any observed AEs will be recorded.  A maximum of 2 1.5cc Radiesse 
syringes will be injected per hand, per treatment visit.  Treatment and retreatment visits 
will be scheduled per Table 2.  There will be no touch-up treatments performed in the 
study.  Subjects will be dispensed a 30-day take-home diary on which to record AEs that 
may occur before their next visit (Appendix B). 
Step-by-step injection instructions are as indicated below from the IFU in Appendix A. 
Technique for Mixing Radiesse injectable implant and 2% Lidocaine HCl 
The following components are required for the percutaneous injection procedure and 
mixing Radiesse injectable implant with lidocaine:

• Radiesse injectable implant syringe(s) – 1.5cc 
• Sterile 27 gauge, 0.5” regular-wall needle with luer lock connector 
• 3.0cc sterile polypropylene luer lock syringe 
 
• 0.2cc of 
 2% lidocaine HCl for injection, USP 
solution (not supplied by Merz North America, Inc.) 
• Sterile female-to-female luer lock connector
 
The Radiesse, sterile needles, 3.0cc sterile polypropylene mixing syringe 
, 
and the female-to-female luer lock connector 
 will be provided in a kit by 
Merz North America, Inc. for the study.  The lidocaine will not be supplied by Merz.  
Component Assembly and Mixing Instructions 
1. Remove foil pouch from the carton containing the Radiesse injectable implant 
syringe.  Open the foil pouch by tearing at the notches (marked 1 and 2), and remove 
the syringe from the foil pouch.  There is a small amount of moisture normally 
present inside the foil pouch for sterilization purposes; this is not an indication of a 
defective product. 
2. Assemble the components and perform the mixing using sterile technique (see Figure 
3).

syringe to the mixing syringe 
 
7.  Mix the lidocaine and Radiesse by alternately depressing the plungers, first on the 
mixing syringe and then on the Radiesse syringe for 10 mixing strokes (each mixing 
stroke is 1 complete compression of the mixing syringe plunger followed by 1 
complete compression of the Radiesse syringe plunger).  Plungers are compressed 
firmly and quickly, at about 2 compressions per second (Figure 6). 
Figure 6.  Mixing strokes. 
8. After mixing, remove the mixing syringe and the female-to-female luer lock 
connector and discard. 
9. Fit the syringe containing the lidocaine and Radiesse mixture with a 27 ID gauge 
injection needle by twisting the syringe of Radiesse onto the luer lock fitting of the 
needle.  Tighten the needle securely to the syringe.  If excess Radiesse is on the 
surface of the luer lock fittings, it will need to be wiped clean with sterile gauze. 
10. Proceed to the “Injection Procedure” below.

Injection Procedure for Hand Augmentation 
1. Prepare subject for percutaneous injection using standard methods.  Have the 
subject wash both hands with soapy water producing friction for 5-10 minutes and 
then prepare hands with suitable antiseptic.  The treatment injection site may be 
marked for planned injection sites.  Jewelry should be removed prior to injection 
and until post-procedure swelling has resolved. 
 
2. Using the syringe of Radiesse injectable implant that has been mixed with 
lidocaine using the procedure described in “Mixing Instructions” above, and fitted 
with the injection needle, slowly push the syringe plunger until Radiesse 
injectable implant extrudes from the end of the needle performing aspiration 
before bolus injection to avoid intravascular injection.  If leakage is noted at the 
luer fitting, wipe it clean with sterile gauze.  It may be necessary to tighten the 
needle, remove the needle and clean the surfaces of the luer fitting or, in extreme 
cases, replace both the syringe and the needle.  A new injection needle may be 
used for each syringe, or the same injection needle may be connected to each new 
syringe. 
 
3. Locate the initial site for injection.  Subjects are to receive injections in the 
dorsum of the hands between the 1st and 5th metacarpals.  Injection should initially 
occur between the 2nd and 4th metacarpals, taking care not to inject close to the 
metacarpophalangeal joints.  If necessary to achieve optimal correction, injection 
is also allowed between the 1st and 2nd, and 4th and 5th metacarpals. 
 
4. Skin tenting should be performed to separate the skin from vascular and tendinous 
structures by using the thumb and forefinger of the non-injecting hand to lift skin 
over the dorsal aspect of the hand being treated. 
 
5. Advance the needle between the subcutaneous layer and superficial fascia with 
the syringe parallel to the dorsum of the hand.  Carefully push the plunger of the 
Radiesse injectable implant syringe to start the injection and inject the Radiesse 
injectable implant material in small boluses, 0.2 – 0.5cc/bolus.  No more than 
0.5cc should be injected per bolus.  The number of boluses will vary depending 
on the extent of treatment desired.  No more than 3cc of Radiesse injectable 
implant (2 syringes) will be injected per hand, per treatment session. 
 
6. If significant resistance is encountered when pushing the plunger, the injection 
needle may be moved slightly to allow easier placement of the material or it may 
be necessary to change the injection needle. 
 
7. Immediately after injection, cover the injection site with a sterile 4x4 gauze and 
have the subject sit on this hand while the contralateral hand is being injected.

This warms the Radiesse injectable implant making it more malleable for later 
massaging. 
 
8. Treat the contralateral hand in the same manner as described in steps 2 through 6 
above. 
 
9. Immediately after injection of the contralateral hand, cover the injection site with 
a sterile 4x4 gauze and have the subject sit on this hand. 
 
10. While the contralateral hand is warming, remove the gauze from the hand that 
was initially injected, have the subject make a fist with this hand, and gently 
massage the dorsum of the hand until Radiesse has been evenly spread across the 
dorsum, remaining distal to the wrist crease and proximal to the 
metacarpophalangeal joints.   
 
11. Use a 1:1 correction factor. No overcorrection is needed.

9 STUDY ASSESSMENTS  
9.1 
Clinical evaluations 
9.1.1 Training and masking of MHGS evaluators 
The MHGS (Figure 1) will be used to measure clinical effectiveness of the Radiesse 
hand treatments by a masked evaluator performing live dorsal hand assessments.  The 
MHGS is an ordinal scale and therefore ratings will be made based on a “snap-shot” at a 
time point and will not be based on a comparison to a pre-treatment photograph.  The 
evaluator will remain masked throughout the study and blinded to knowledge of 0 to 3 
repeat treatments during the study.  Prior to study initiation, the masked evaluator will be 
trained and qualified by the study Sponsor to perform MHGS assessments.  Training will 
consist of an instructional webinar and qualification will consist of the masked evaluator 
trainee scoring 2 25-subject photo booklets, at least 1 week apart for intra-rater weighted 
Kappa analyses prior to study initiation.  Retraining will occur if a minimal weighted 
Kappa value is not achieved (≥ 0.60), with qualification required prior to screening 
subjects for the study, prior to initial X-ray and Radiesse treatment in the study.  If a 
repeat hand treatment is scheduled during a study visit, the MHGS assessment will be 
completed prior to treatment.  To ensure that the blind is maintained, subjects will have 
their upper body and face hidden behind a barrier screen with only their hand visible to 
the masked evaluator.  Subjects will be asked to remain silent during the MHGS 
evaluation process.  Masked evaluators will not be allowed to discuss treatment schedules 
with treatment investigators and study staff at the site, and will not enter data on case 
report forms (CRFs) that contain information that would break the blind. 
9.1.2 Evaluation of aesthetic improvement 
To assess the aesthetically pleasing aspect of the Radiesse hand treatment outcomes, 
subjects will perform self-assessments on the GAIS shown in Table 1.  The GAIS is a 
relative scale, therefore the subjects will be asked to perform the rating compared to 
baseline pre-treatment photographs. 
9.1.3 Evaluation of hand function 
 
 
  Subjective functional 
outcomes will also be assessed at baseline and at 1-, 3-, 6-, 7-, 12-, 13-, 18-, 19- and 24-
months following initial injection of Radiesse using the validated MHQ (Appendix C).  
The MHQ is a patient-rated outcome tool based on psychometric principles that is 
capable of measuring health status domains that are important to patients with hand 
disorders.

9.1.4 Evaluation of hand X-rays 
 
X-rays will be taken at a licensed radiographic imaging center.  Plain anteroposterior and 
lateral views (Figure 7) of each hand will be taken at each required study timepoint.  
Digitized radiographic images will be transmitted to the imaging core lab to be assessed 
by 2 blinded, licensed radiologists.  Copies of digitized X-rays will be sent from the 
imaging center to the investigational site and the Sponsor.  The core lab will send 
confirmation of completed X-ray assessments to the investigational site and the Sponsor.  
The core lab will send results of the X-ray assessments to both the site and Sponsor 
within 21 days of receiving the digital X-rays from the imaging center.  Results of the 6-
month X-ray assessments will be used to determine the need to schedule X-rays prior to

the 12-month in-office follow-up visit.  After completion of all 18-month follow-up visits 
at the site, both the local licensed imaging center and core lab will be informed of the 
total number of subjects who will be scheduled for 24-month X-rays.  Only subjects who 
receive a total of 4 Radiesse hand treatments (initial, 6-, 12-, and 18-month treatments) 
will be required to have X-rays of their hands prior to the final study visit at 24-months.

metacarpal.  The hand was not implanted with Radiesse. 
A = anteroposterior view, B = lateral view. 
 
The core lab radiologists will remain blinded to the study design, including any study 
timepoints that might involve Radiesse hand treatment.  Timepoints will be listed by 
number of months from enrollment, and will not include any unblinding descriptors (e.g., 
injection visit).  Further, the core lab radiologists will be asked to compare the 
prominence of any foreign material to that of the previous x-ray for that subject (where 
applicable).  Consequently, documentation of the study timepoint associated with the x-
ray image being read does not impact the integrity of the data reported by the core lab 
radiologists. 
9.2 
 Visit schedule 
Screening and Enrollment 
Enrollment will be limited to 20 subjects for the study. The Sponsor will oversee 
enrollment and be in direct communication with the investigational site to make all 
efforts not to exceed the enrollment target of 20 subjects, and to ensure that Groups A 
and B (described in Section 7) are fully enrolled.  Presenting subjects may be pre-
screened to the selection criteria identified in Sections 7.2 and 7.3.  If it is determined that 
a presenting subject meets these selection criteria, the subject will be given an Informed 
Consent Form to review and sign.

There will be 3 visits during the screening and enrollment period: 2 at the investigational 
site, and 1 at the local X-ray imaging center.  The X-ray visit may be performed on the 
same day as the consent or injection. 
Upon the subject’s provision of informed consent to participate in the study, the subject 
will be enrolled in the study and assigned a study ID number. The number will contain 3 
parts – trial identification code (XR = X-Ray), site identification number, and subject 
enrollment order number. For example, the third subject enrolled will receive study ID 
number XR-1-03. The masked evaluator will assess hands on the MHGS to meet hand 
rating requirements for inclusion. Enrolled subjects will be assigned to Group A or B 
based on baseline MHGS ratings until both groups are fully enrolled. Study information 
including demographics and concomitant medications will be recorded, and photographs 
will be taken of each hand. The subject will then be scheduled for hand X-rays to be 
taken prior to Radiesse hand treatment. 
Within 72 hours after enrollment: Subjects will have X-rays taken of their hands at a 
designated, local, licensed imaging center. 
Week 1/Initial treatment visit: 7 ± 6 days from enrollment, all subjects will return for a 
follow-up visit after completing the corresponding X-ray visit to the designated imaging 
center. This visit can be scheduled on the same day as the X-ray visit. Females of 
childbearing age will complete a urine pregnancy test. The subject’s hands will be 
assessed on the MHGS by a live, masked evaluator. Subjects will complete the MHQ 
 
. At this time, subjects will receive a Radiesse 
treatment. A take-home 30-day diary will be given to the subject. A physician will assess 
the subject’s hands for AEs. Photographs of the hands will be taken only in the event of a 
serious or medically concerning AE. Subjects will be scheduled for the Month 1 X-ray 
and follow-up visits. 
Follow-Up Evaluations 
72 hours after Week 1/initial treatment: Subjects will be scheduled for a phone visit 72 
hours after treatment to assess for AEs. Subjects will be reminded to continue daily 
entries into their 30-day diary.

10 SAFETY ASSESSMENTS 
All AEs observed by study subjects, investigators or other study staff from informed 
consent through last study follow-up visit will be recorded.  If a SAE or USADE occurs, 
study subjects may be requested to appear for unscheduled follow-up visits for AE 
assessment and hand photographs.  
The following information, at minimum, must be recorded:  
• 
AE description 
• 
AE type (serious, expected, unexpected) – Refer to definitions below 
• 
Start and Stop Dates  
• 
Intensity (mild, moderate, severe) – Refer to definitions below 
• 
Causal relationship (not related, related) – Refer to definitions below 
• 
Treatment description, if any 
10.1 Definition of intensity 
The clinical intensity of an AE will be classified as: 
Mild: Signs and symptoms that can be easily tolerated. Symptoms can be ignored and 
disappear when the subject is distracted. 
Moderate: Signs and symptoms that cause discomfort and interfere with normal 
functioning, but are tolerable. They cannot be ignored and do not disappear when the 
subject is distracted. 
Severe: Signs and symptoms that affect usual daily activity and incapacitate the subject, 
thereby interrupting his/her daily activities. 
The definitions above are difficult to apply for some data (e.g., clinically relevant 
laboratory values that are documented and evaluated on the CRF AE report form). In 
such situations, the investigator should make a judgment based on personal experience. 
10.2 Definition of causal relationship  
An AE is considered to be “related” to investigational product (IP) if a causal relationship 
between the IP and an AE is at least a reasonable possibility (i.e., the relationship cannot 
be ruled out) in the opinion of the investigator.

 SOP/245/EN - CLINICAL STUDY PROTOCOL

The expression “reasonable causal relationship” is meant to convey that there are facts 
(evidence) or arguments to suggest a causal relationship (ICH E2A guideline).  
Otherwise, the relationship should be considered as “not related.” 
10.3 Definition of type  
10.3.1 Adverse event 
The general definition for an AE is an untoward medical occurrence which does not 
necessarily have a causal relationship to the investigational product. 
10.3.2 Serious adverse event 
A SAE is an AE that meets at least 1 of the following 6 criteria: 
(1) 
Results in death. 
(2) 
Is life-threatening.8  
(3) 
Requires inpatient hospitalization, or prolongation of existing hospitalization. 
(4) 
Results in persistent or significant incapacity or substantial disruption of the ability 
to conduct normal life functions. 
(5) 
Is a congenital anomaly/birth defect. 
(6) 
Is an important medical event.9 
All SAEs that occur during the study period, whether considered to be related to the IP or 
not, must be reported by e-fax within 24 hours of knowledge of the event.  
  
Please fax completed SAE forms to:

Raleigh, North Carolina 27615 
e-fax: 1-336-458-5983 
                                                          
8 Defined as the subject being at risk of death at the time of the event; it does not refer to an event that 
hypothetically might have caused death if it were more severe. 
9 According to ICH E2A, CPMP/ICH/377/95: “Medical and scientific judgment should be exercised in 
deciding whether expedited reporting is appropriate in other situations, such as important medical events 
that may not be immediately life-threatening or result in death or hospitalization but may jeopardize the 
patient/subject or may require intervention to prevent one of the other outcomes listed in the definition 
above. These should also usually be considered serious. Examples of such events are intensive treatment in 
an emergency room or at home for allergic bronchospasm; blood dyscrasias or convulsions that do not 
result in hospitalization; or development of drug dependency or drug abuse.”

Although all information required for completion of an SAE report form may not be 
available within the specified time period, the following minimal initial information 
should be reported: Subject ID #, Site #, name and contact information (of 
investigator/study coordinator), which of the 6 SAE criteria identified above resulted in 
the event being deemed “serious”.  
 
IRB reporting requirements may also apply for SAEs.  
10.3.3 Unanticipated adverse device effect  
 
An unanticipated adverse device effect is any serious adverse effect on health or safety or 
any life-threatening problem or death caused by, or associated with, a device, if that 
effect, problem, or death was not previously identified in nature, severity, or degree of 
incidence in the IFU or Radiesse labeling, or any other unanticipated serious problem 
associated with a device that relates to the rights, safety, or welfare of subjects. 
10.3.4 Expected adverse events 
An expected AE is an experience listed in the current IFU (Appendix A). 
10.3.5 Unexpected adverse events 
An unexpected AE is an experience not previously reported in nature, severity, or 
incidence in the current IFU.  IRB reporting requirements may also apply.

QUALITY CONTROL AND QUALITY ASSURANCE 
11.1 Monitoring 
This study will be monitored in accordance with GCP and regulatory guidelines.  By 
signing this protocol, the investigator agrees to periodic, on-site monitoring of all 
appropriate study documentation. The progress of the study will be monitored by periodic 
on-site visits and frequent communications between the Sponsor (or designee) and the 
investigator (either by phone, fax, email, or post). During these contacts, the monitor will: 
• 
Check and assess the progress of the study. 
• 
Conduct source document verification to ensure data are authentic, accurate, and 
complete. 
• 
Identify any issues and address their resolution.  
• 
Ensure the safety and rights of subjects are being protected. 
• 
Verify that the study is being conducted in accordance with the currently 
approved protocol (and any amendments) per GCP and all applicable regulatory 
requirements. 
In addition, the monitor will check whether all AEs and SAEs have been reported 
appropriately within the time periods required. 
The investigator and all staff will be expected to cooperate with the monitor by providing 
any missing information whenever possible. The investigator must be available to answer 
questions arising during regular monitoring visits. 
11.2 Audits / Inspections 
Audits may be performed, including the possibility that a member of the Sponsor’s 
quality assurance function or their representative may arrange to visit the investigator in 
order to audit the performance of the study at the study site, as well as all study 
documents originating there.  
Inspections by regulatory authority representatives and IRBs are possible at any time, 
even after the end of study. The investigator is to notify the Sponsor immediately of any 
such inspection.  The investigator and institution will permit study-related monitoring, 
audits, reviews by the IRB and/or regulatory authorities, and will allow direct access to 
source data and source documents for such monitoring, audits, and reviews.

STATISTICAL METHODS 
This section describes the statistical analyses foreseen at the time of study planning. 
Any deviations from planned analyses, the reasons for such deviation, and all alternative 
or additional statistical analyses that may be performed before database close will be 
summarized in the clinical study report. 
12.1 Determination of sample size 
Given that the study is a radiologic evaluation to obtain a preliminary assessment, the 
planned sample size is not based on power calculations for a formal statistical hypothesis 
test, but rather is based on a clinically relevant sample of subjects that will provide a 
degree of characterization regarding the ability to perform radiologic evaluations after 
treatment with Radiesse. Minimizing the sample size helps prevent unnecessary exposure 
to radiation. 
12.2 Analysis sets    
Analyses will be based on all enrolled subjects with available data. The primary event of 
interest, and primary endpoint of the study, is whether treatment with Radiesse interferes 
with radiological assessment by obscuring the bones of the hand at any time during the 
study. Obscuration is defined as any hand X-ray that at least 1 of the 2 blinded imaging 
core lab radiologists interprets as Radiesse obscuring bones. This will be based on 
assessments performed post-treatment. In addition, for subjects with pre-treatment 
assessments, paired comparisons will be made informally to assess clinically relevant 
issues on the pre/post treatment X-rays. Corresponding two-by-two tables for paired 
measurements, and 95% exact binomial confidence intervals for results by visit will be 
calculated. No formal hypothesis tests are planned but nominal results from tests may be 
reported based on exploratory analyses. 
12.3 Variables for analysis 
12.3.1 Primary safety variable 
The primary safety variable is number and percent of subjects with an X-ray of either 
hand with obscuration of the bones of the hand at 1-, 6-, 12-, and 24-months as 
interpreted by at least 1 of 2 blinded radiologists at the imaging core lab.

12.3.2 Secondary efficacy and safety variables 
The secondary efficacy and safety variables are as follows: 
 
• 
The number and percent of subjects with at least a 1 point improvement in 
MHGS in both hands at 1- and 6-months after initial treatment 
• The number and percent of subjects with at least a 1 point improvement in 
MHGS in both hands at MHGS at 1- and 6-months follow retreatment for 
those receiving retreatment 
• The frequency distribution of GAIS values at 1 and 6-months after initial 
treatment 
• The frequency distribution of GAIS values at 1- and 6-months follow 
retreatment for those receiving retreatment 
• MHQ scores at baseline, study exit, and other collected time points. The rate 
of device/injection-related severe AEs at 1- and 6-months 
12.3.3 Other efficacy and safety variables 
Other efficacy and safety variables are as follows: 
• 
MHGS at 12-, 18-, and 24-months after initial treatment 
• MHGS at 12- and 18-months follow retreatment for those receiving 
retreatment 
• GAIS at 12-, 18-, and 24-months after initial treatment 
• GAIS at 12- and 18-months follow retreatment for those receiving retreatment 
• The rate of device/injection-related severe adverse events at 12-, 18- and 24-
months 
• Incidence of all AEs over the course of the study 
 
 
 
 
12.4 Statistical analysis methods 
12.4.1 Primary safety variable 
The primary event of interest is whether treatment with Radiesse interferes with 
radiological assessment by obscuring the bones of the hand at any time during the study. 
This will be based on assessments performed post-treatment. Analysis will be made by-
subject, and reported. In addition, for subjects with pre-treatment assessments, paired 
comparisons will be made informally to assess clinically relevant issues on the pre/post 
treatment X-rays. Corresponding two-by-two tables for paired measurements, and 95% 
exact binomial confidence intervals for results by visit will be calculated. No formal 
hypothesis tests are planned but nominal results from tests may be reported based on 
exploratory analyses.

12.4.2 Secondary and other efficacy and safety variables 
Analysis will be performed to determine MHGS changes from baseline, and if treatment 
effects were aesthetically pleasing in the hands after treatment as reported on the GAIS 
Threshold of MHGS improvement will be at least 1 point improved for effective analysis, 
as percent of subjects with both hands improved. Groups A and B will be analyzed 
separately and in aggregate. Confidence intervals will be based on a 5% nominal alpha 
level. 
AEs will be summarized descriptively including type, duration, severity, relationship to 
study device, incidence of recurrence, and need for treatment by hand. The analysis will 
include the incidence of all AEs over the course of the study. 
Descriptive statistics will be provided for the MHQ at baseline, study exit, and other 
collected time points.

DATA HANDLING AND RECORDKEEPING 
By signing and dating the CRF, or electronic signature of the electronic case report form 
(eCRF) if an Electronic Data Capture (EDC) system is used, the investigator will confirm 
that all investigations have been completed and conducted in compliance with the clinical 
study protocol, and that reliable and complete data have been entered into the CRF. 
All data required by this clinical study protocol are to be recorded on CRFs, or eCRFs, as 
soon as possible. If paper-based, entries on the CRF must be legible and made with a blue 
or black ballpoint pen: pencils are not permitted. The monitor is not allowed to make 
entries into a paper-based CRF or eCRF. 
For paper-based CRFs, it is not permitted to erase, overwrite, or use correction fluid or 
tape on the CRF. If corrections are necessary, an authorized member of the investigator’s 
staff will enter them in the following manner: the wrong entry will be crossed out with a 
single line (although it must remain legible) and the correct entry will be placed next to it.  
Corrections will be initialed, dated, and (if necessary) explained (e.g., corrections 
concerning AEs or the primary variable).Corrections that become necessary after 
collection of original CRF data sheets have to be documented on Data Clarification 
Forms (DCFs) and signed by the principal investigator (PI). 
All data required by this clinical study protocol are to be entered into an EDC system if 
applicable, and a validated database, which applies to both paper-based and EDC 
systems.  
If corrections in the subject diary or subject MHQ are necessary, the subject should be 
instructed to make a correction by drawing only a single line through the error, leaving 
the incorrect entry legible. The subject should date and initial the correction. The 
investigator should not make any changes to these documents. 
Essential documents at the investigational site include but are not limited to: 
(1) 
Subject files 
(2) 
Subject identification code list  
(3) 
A copy of the study protocol and any amendments 
(4) 
Investigator’s copies of the CRFs, DCFs, and any associated subject-related 
source data 
(5) 
Signed ICFs 
(6) 
Copies of all direct correspondence with the IRB and with the regulatory 
authority(ies), and with the Sponsor 
(7) 
Copies of hand photographs

Copies of IP disposition records 
Essential documents should be retained per applicable regulations and as instructed by 
the study Sponsor. Study documents may not be destroyed by study site personnel prior 
to the end of the required retention period of 25 years. The PI or the institution must 
inform the Sponsor in due time if the PI leaves the institution during the retention period.  
This rule also applies when the institution closes within the retention period.
