1. Background and Rationale 
 
Submental fat accumulation is a common concern amongst patients presenting for a cosmetic 
dermatologic consultation.  Liposuction was employed previously for aesthetic improvement.  
However, alternative non-invasive techniques such as cryolipolysis, focused ultrasound, 
radiofrequency, and injectable sodium deoxycholate (SDOC) have been developed to meet 
the increasing demand for minimal downtime procedures.  Patient experience with SDOC 
has been less than optimal, however, with approximately only 1in 4 patients returning for 
more than one treatment. 
Subcutaneous pure synthetic SDOC (Kybella™, Allergan) gained FDA approval for 
reduction of submental fat in June 2015.  When injected into submental fat, Kybella(TM) 
ultimately results in focal adipocytolysis and focal destruction of fat cells.  An excellent 
pharmacokinetic safety profile has been demonstrated, with no measurable increases in 
serum cholesterol, triglycerides, or free fatty acids detected 24 hours following injection [1, 
2].  Furthermore, four large phase III clinical trials to date have demonstrated the efficacy of 
Kybella(TM) in the reduction of submental fat [3]. 
Despite the documented safety and efficacy of Kybella(TM), many patients experience a 
variable degree of edema and pain following subcutaneous injection which can sometimes 
last for several days to weeks and can be a significant cause for concern.  The mechanism of 
edema and pain secondary to Kybella(TM) injection is unknown but thought to be an irritant 
response directly related to deoxycholate and not subsequent adipocyte lysis and death.  This 
edema and pain is thought to be a major factor contributing to the relatively small percentage 
of patients returning to complete the full treatment regimen.   This study proposes to answer 
the question of whether immediate swelling and pain can be reduced to increase patient 
tolerance and improve patient experience without reducing the longer term low level 
inflammatory component which results in visible and measurable submental fat reduction. 
A previous study was performed using high doses of a corticosteroid.  This double-blind, 
randomized study utilized triamcinolone acetonide (TMC), a corticosteroid compound, in 
conjunction with Kybella(TM) showed that the addition of TMC reduced the incidence of 
early edema and tenderness, but negatively impacted long term efficacy and produced 
cutaneous changes of steroid atrophy in 7 (47%) of the 15 patients treated with TMC [4]. In 
the study, 2.0 mL of 2 mg/cm2 of Kybella(TM) was mixed with 0.05 mL of 40 mg/mL of 
TMC, and was delivered in up to 50 injections spaced 1.0 cm apart at 0.25 mL/injection for a 
total dose of up to 100 mg of Kybella(TM). As the tolerability of Kybella(TM) remains a 
significant issue in patient care, perhaps lower concentrations of TMC would be effective in 
reducing side effects without compromising treatment efficacy and causing steroid atrophy.

2. Study Objective & Hypothesis 
 
The primary objective of this study is to evaluate the efficacy, edema and pain associated with 
Kybella(TM) injections of the upper neck in the treatment of submental fat with low 
concentrations of triamcinolone acetonide plus low doses of lidocaine.  An evaluator blinded to 
the study will grade the level of improvement of the submental fat.  Safety will also be assessed. 
 
The Working Hypothesis: The combination of Kybella(TM) and with very low dose 
triamcinolone acetonide is effective in the reduction of immediate edema associated with 
Kybella(TM) injections and does not adversely affect the previously demonstrated long term 
reduction of submental fat. Addition of 0.1% lidocaine will provide immediate pain relief for a 
better patient experience.  As 1% lidocaine is already injected just prior to Kybella injection as 
per current treatment protocol, there is no anticipated effect from low dose 0.1% lidocaine other 
than anesthesia. 
 
3. Study Design 
 
This is a two-site randomized, double-blind comparison trial of Kybella(TM) injections with or 
without triamcinolone acetate for the reduction of submental fat.  30 subjects will be enrolled 
into the trial (15 subjects per site).  At each site, 5 will be randomized to receive Kybella(TM) 
injections alone whereas 10 will receive Kybella(TM) plus differing doses of triamcinolone 
acetate in the following way: 
1. Group 1 (5 patients per site): Kybella(TM) alone: 2 mg/cm2 of Kybella(TM) with 0.2 mL 
of 1% lidocaine with no epinephrine plus 0.2cc saline to the non-TMC group to 
maintain equal concentrations in each injection so that the final Kybella concentration per 
vial will be 10mg/1.2mls or 1.6mg per 0.2 cc injection point will be delivered in up to 50 
injections spaced 1.0 cm apart at 0.2 mL/injection for a total maximal dose of up to 100 
mg of SDOC. 
2. Group 2 (10 patients per site): Kybella(TM)+TMC at 1.0 mg/mL: 2.0 mL of 2 mg/cm2 of 
Kybella(TM) will be mixed with 0.2 mL of 10 mg/mL of triamcinolone acetate, 0.2 mL 
of 1% lidocaine with no epinephrine and then delivered in up to 50 injections spaced 
1.0 cm apart at 0.2 mL/injection for a total dose of up to 100 mg of SDOC using a 30 
gauge (or smaller) 0.5-inch needle. The final Kybella concentration per vial will be 
10mg/1.2mls or 1.6mg per 0.2 cc injection point 
 
The treatment area will be bounded superiorly by a line 1 cm inferior to the mandibular margin, 
laterally by the sternocleidomastoid muscles, and inferiorly by the hyoid bone.  The subjects and 
evaluating investigator will be blinded to the treatment, thus maintaining double-blind status.  By 
nature of the varying volumes of injection, the treating investigator will be unblinded to the 
treatment.  A series of 3 injection sessions will be performed spaced 4 weeks apart.  No lidocaine 
will be injected prior to injections to prevent further dilution of injected Kybella™ as it will be 

Page 4 of 17 
 
premixed with Kybella™.   Chilling with cold will be the method of pain reduction for needle 
insertion. 
Canfield Vectra 3D imaging will be performed at baseline and final visit (Appendix C) with 
analysis and calculation of volumetric changes performed at baseline and final visit. Photos will 
also be taken with the Intellistudio at all other visits.  Follow up visits will be performed 3 and 5 
days after each injection session to assess for side effect and tolerability profile.  After the final 
injection session, additional follow up visits will be performed at days 90 and 180 to assess for 
efficacy.  Subject weight will be recorded at baseline and at end of study.

13. Adverse Events and Reporting  
Serious and/or Adverse Event and Reporting 
 
A serious adverse event is any untoward medical occurrence, that, at any dose: 
- 
Results in death; 
-  
is life-threatening; 
- 
requires 
in-subject 
hospitalization 
or 
prolongation 
of 
existing 
hospitalization; 
- 
Results in persistent or significant disability/incapacity;  
- 
is a congenital anomaly/birth defect; or 
 
- 
is an important medical event.  
An unexpected adverse event is any treatment-related adverse event, which is not identified in 
nature, severity, or frequency in current literature on the test product. 
 
Any serious adverse event occurring in this study must be reported to the IRB within 24 hours of 
awareness of the event. Initial reports must be made by telephone, followed by the completion of 
a Serious Adverse Event Report and submission by facsimile.    

Page 13 of 17 
 
 
Throughout the study, subjects will be monitored for signs and symptoms of adverse events.  An 
adverse event is any pathological or unintended change in the structure, function or chemistry of 
the body that occurs during the study, irrespective of causality, including any illness, injury, 
toxicity, sensitivity, or sudden death.  The condition must either not be present pre-study or must 
worsen in either intensity or frequency during the study. 
All adverse events, including serious and treatment related or unexpected adverse events, must 
be recorded by the Investigator.  In the event of an adverse event or serious adverse event, the 
physician will provide optimal patient care. 
 
Subjects who have had a serious adverse event must be followed clinically until all parameters 
have either returned to normal or are otherwise explained.  If death was the outcome of the event 
on the initial SAE Report, a Follow-up/Final Report, including autopsy report, when performed, 
must be completed. 
 
14.    DATA ANALYSIS 
 
A blinded investigator will grade the side effects on a scale of 0-4 to assess erythema, edema, 
tenderness, and erosion/ulceration at each follow-up visit and utilize the Clinician-Reported 
Submental Fat Rating Scale of 0-4 will be completed on Visit Days 1, 30, 60, 90 and 180.   
 
The subject will evaluate the side effects of bruising, pain, swelling, tolerability, and interference 
in daily function on a scale of 0-4 at all follow-up visits and complete the Subject Satisfaction 
Rating Scale of 0-6 on Visit Day 180 (See Appendix B).  The investigator will also evaluate the 
side effects of bruising, pain, swelling, tolerability, and interference in daily function on a scale 
of 0-4 at all follow up visits.  
 
A p value of 0.05 or less will be considered significant.

Clinician-Reported Submental Fat Rating Scale (CR-SMFRS) 
Score 
SMF Description 
0 
Absent Submental Convexity:  No localized submental fat evident. 
1 
Mild Submental Convexity:  Minimal, localized submental fat. 
2 
Moderate Submental Convexity:  Prominent, localized submental fat. 
3 
Severe Submental Convexity:  Marked, localized submental fat. 
4 
Extreme Submental Convexity. 
 
Clinician Evaluation: Submental Skin Laxity Grade (SMSLG) 
Grade 
Laxity Description

Page 15 of 17 
 
3 
Moderate 
 May have moderate superficial wrinkling 
 Skin has mild to moderate separation from deeper neck structures 
 Moderate skin redundancy 
 Moderate skin draping (vertical folds) 
 Minimal to mild skin sagging (horizontal folds)  
4 
Severe 
 Superficial wrinkling present, may be marked 
 Loose skin separated from deeper neck structures 
 Marked skin redundancy  
 Marked skin draping (vertical folds) 
 Marked skin sagging (horizontal folds) 
 
Assessment Procedures 
The SMSLG is an integration of three features: skin wrinkling, adherence to underlying neck 
structures (bone and muscle) and redundancy (horizontal and vertical folds).  Each grade (none, 
mild, moderate and severe) defines the maximal allowed limit for skin wrinkling, adherence to 
underlying structures and redundancy. 
SMSLG is based on assessor’s clinical evaluation of the subject, including palpation of the chin 
and neck area; anterior, oblique, and profile views of the chin and neck; as well as observation of 
pronation, supination, and lateral movement of the head.  The score is determined using the 
definitions in the rating scale and representative photographs associated with each score.  The 
final determination of the score will be made while the subject’s head is in the Frankfort plane 
posture.  The score will be recorded as a whole number.

Standardized Vectra Photography  
 
Photos will be taken in a standardized fashion: 
*Standard lighting and camera positioning to ensure comparable before and after treatment 
photographs of the face (VECTRA photos are always done in the same room) approximately 2 
feet away from base of system. 
 
                  
 
 
Please ensure the following for consistent before and after photos: 
 
1. Subjects removal of makeup and face washed at least 20 minutes prior to having their 
photograph taken to ensure makeup, lotions and/or sunscreens will not interfere with any 
evaluations (Males must be clean shaven). 
2. Please ensure that subjects jewelry is removed from ears/neck and hair is pushed back away 
from the face with a black headband (any stray hairs will cause the VECTRA system to crop the 
face). A black drape will be placed around the subjects neck to ensure photo consistency. 
One (1) photo will be taken with eyes closed one (1) image will allow us to capture (5) views 
(frontal, left oblique, right oblique, left profile and right profile views). The camera we will be 
using is a Canfield VECTRA. Photos will be captured at ALL visits (on treatment visits day 1, 
30 and 60 photos will be captured pre-treatment).
