Programming note:  Differentiation between Early term and Follow-up is based on the availability of V10 (1st 26 Weeks) or V16 (patients entering 
extension) data for ANY data (not just global assessments).  If a patient does not enter the extension and had no data collected for V10 and had 
discontinued the trial the follow-up is considered “Early Term 1st 26 Weeks”.  If they had V10 and did not enter the extension then it’s “Follow-Up 6 
Month Extension”.  Similarly for those entering extension, those without a V16 who discontinued the study are assigned “Early Term 6 Month 
Extension” and those with V16 are assigned to “Follow-Up 6 Month Extension”.

You are currently participating in Aclaris Therapeutics, Inc.’s ATI-50002-VITI-201 study, and the 
study doctor or study staff has asked you to read and sign this Addendum to the Consent Form.  
Everything in the main study consent form you signed before still applies to your participation in 
this study unless otherwise noted in this form.  
This form describes additional information about the study.  If you have any questions about or 
do not understand something in this form, you should ask the study doctor or study staff.  You 
should also discuss your participation with anyone you choose in order to better understand this 
study and your options. 
 
WHAT IS THE PURPOSE OF THIS ADDENDUM? 
Since the time you signed the last consent form for this study, new information related to the 
study has become available:  
The study sponsor has decided to increase the duration of the study to allow application of ATI-
50002 Topical Solution, 0.46% (study drug) to your face and if you have vitiligo on your neck to 
your neck also from 24 weeks up to 48 weeks with a 4-week after treatment follow-up visit.  You 
had previously indicated that you wanted to apply study drug for up to 24 weeks only.  If you 
would like to continue applying the study drug for the additional 24 weeks being offered, you will 
have to read and sign this consent addendum and then come into the clinic for four extra visits 
(Visits 12, 13, 14, & 15) scheduled 3 months apart which were not originally planned.  You will 
then come in for a final visit as originally planned 1 month after you last use the study drug (Visit 
16).  During these visits, the following tests may be performed by the study staff:

• 
Physical Exam:  The study doctor or a member of the study staff will examine your 
overall general appearance, head, eyes, ears, nose, throat, stomach, nervous system, 
muscles and bones, lymphatics, and skin, and will listen to your heart and lungs. 
• 
Vital Signs:  Check your blood pressure by putting a band around your arm (this will 
squeeze your arm for about a minute), check your pulse, listen to you breathe in and out, 
and take your temperature. 
• 
Blood Testing:  Take some blood through a needle in your arm to do safety and 
laboratory tests.  If you continue with 4 additional visits, the maximum amount of blood 
you will have taken over the 52 weeks is slightly less than ¾ cup. 
• 
Urine Testing:  You will have your urine tested. 
• 
Pregnancy Testing:  Test your blood and/or urine to see if you are pregnant.  You will 
only have pregnancy testing if you are a woman and can have children. 
o The study doctor or study staff will tell you if the pregnancy test results are 
positive. 
o The results of the pregnancy testing must be negative in order for you to be 
enrolled in and continue in the study. 
• 
Electrocardiogram:  An electrocardiogram (ECG) measures the electrical activity of 
your heart. 
• 
Changes in Health or Medication Questions:  You will be asked about any changes in 
your health and the medications you are taking since the previous study visit. 
• 
Skin Examinations:  The study doctor or study staff will examine your face to determine 
the amount of white patches.  
• 
Questionnaires:  You will examine your face to determine and describe the appearance 
and severity of your facial vitiligo (white patches), and assess the impact of the facial 
vitiligo on your life.  At Visits 12, 13 and 14 (Day 225, 281 and 337) you will be asked to 
rate your satisfaction with the study drug results.   
• 
Photography:  The study doctor or study staff will take pictures of your face (your face 
will be included in these photographs) to document the white patches. These 
photographs may be used for research purposes related to the study and for 
presentation to government health authorities, such as the U.S. Food and Drug 
Administration (FDA), at scientific meetings, for scientific publications, for general 
corporate purposes, and may be used for marketing purposes. Your identity will not be 
revealed in these photographs.  Your identifying features, (eyes, mouth, tattoos) will be 
hidden in the photographs.  You do not have to let the study doctor or study staff 
take photographs if you don’t want to; however, if you decline to have these 
pictures taken, you will not be allowed to participate in this study. 
• 
Study Drug:  You will be given a supply of study drug and instructions for how to apply 
the study drug. 
• 
Subject Instruction Sheet:  You will be given a written instruction sheet.

Investigational product, dosage and mode of administration:  
Open label ATI-50002 Topical Solution 0.46% will be applied to the balding area of male and female 
subjects with androgenetic alopecia.  Up to 4mls of ATI-50002 Topical Solution 0.46% will be 
applied to the scalps of eligible study subjects twice a day using a 1ml disposable dropper.   
Duration of treatment:  
All subjects will apply ATI-50002 Topical Solution 0.46% twice a day for 26 weeks.  Subjects will 
have the option to consent to remain on study for an additional 26 weeks.  All subjects will be 
required to have a safety follow up visit 4 weeks after their last application of study medication.   
Study Endpoints:   
Efficacy: 
The primary efficacy endpoint is the change from baseline in non-vellus target area hair count 
(TAHC)using a microphotographic technique. 
 
The secondary efficacy endpoints are defined as: 
• development of new hair growth/scalp coverage as assessed by the investigator and 
the subject using a seven-point rating scale and subject global scalp photographs.  
• Change from baseline in cumulative target area hair width (TAHW)  
• Change from baseline in AGA stage according to the Norwood Hamilton scale in 
males and the Sinclair Scale in females 
Safety: 
Subjects will be assessed for local skin reactions and adverse events throughout the duration of the 
trial.  In addition, vital signs, ECGs and clinical laboratory assessments will be performed on all 
subjects at the protocol defined time-points.  
Statistical methods: 
Summary descriptive statistics (N, mean, median, SD) by visit will be provided for all safety and 
efficacy parameters. The Intent to Treat population will be used for all efficacy assessments and the 
Safety population will be used for all safety assessments. No data imputation will be used.  Primary 
and secondary efficacy parameters are described below: 
 
Primary Efficacy Endpoints: 
Mean change from baseline in non-vellus target area hair count (TAHC)will be quantified using a 
microphotographic technique and calculated along with the median, standard deviation, standard 
error, and 95% confidence limits around each mean change to allow tests of the null hypothesis that 
the population mean changes are zero. 
 
Secondary Efficacy Endpoints: 
Mean change from baseline in cumulative target area hair width (TAHW) will be quantified using a 
microphotographic technique and calculated along with the median, standard deviation, standard 
error, and 95% confidence limits around each mean change to allow tests of the null hypothesis that 
the population mean changes are zero.

The seven-point rating scale to measure the investigator and subject assessment of the development of 
new hair growth/scalp coverage will be analyzed with summary statistics (N, mean, median, SD) for 
each visit where the assessment is made.  Similar summary statistics will be used to analyze change 
from baseline in AGA stage separately for males (Horwood Hamilton Scale) and for females (Sinclair 
Scale) at each applicable visit.  
 
Safety Assessments: 
Data from all enrolled and treated subjects will be presented and summarized. Safety analyses will 
include descriptive statistics calculated on the safety parameters using the safety population. The 
proportion of subjects with treatment-emergent adverse events will be tabulated and presented by 
Medical Dictionary for Regulatory Activities (MedDRA) System Organ Class. Vital signs and 
clinically significant abnormal laboratory results will also be tabulated and presented.  Clinical 
laboratory and ECG results will be tabulated, highlighting abnormal results.  Local skin reaction 
results will be tabulated and summarized by visit.

AMENDMENT HISTORY 
4.1. 
Amendment Rationale 
Version 2.0 amendment 1 dated 16 January 2018, clarified the size of the area of the subject’s 
scalp that would be required to be clipped at each protocol defined timepoint.  The original 
protocol identified the area on the subject’s as a 1cm2 target area.  The accurate clipping size to 
perform the TAHC and TAHD is a 1.9 cm diameter circle clipped to ~ 1mm in length.  The 
subject inclusion criteria were also amended to require that subjects refrain from strenuous 
exercise that would cause profuse sweating for a period of 6 hours after application of study 
medication.  This requirement was added to ensure that the study medication was absorbed prior 
to performing any strenuous exercise.  The subject exclusion criteria were amended to allow 
subjects to enroll to the study if they have previously received treatment with a topical JAK 
inhibitor.  The use of systemic steroids for more than 14-day s in the 2 months prior to Visit 2 
was added to the prohibited medication section and the use of anabolic steroids prior to Visit 2 
was changed from 3 months to 6 weeks.   Section 11.3.6 was added to the protocol to provide 
definitions for protocol violations and protocol deviations.   
 
Version 3.0 amendment 2 dated 01 February 2018, added in the secondary objective to assess the 
change from baseline in target area hair width.  This objective should have been included in the 
original protocol.  The protocol was also amended to allow pre-menopausal women to enroll to 
the study.   
 
Version 4.0 amendment 3 dated 16 October 2018, allows subjects enrolled to the study to receive 
an additional 6 months of study medication.  Creatine Phosphokinase (CPK) was also added to 
the chemistry panel as an additional safety assessment.  The amount of study medication 
dispensed at each visit was also amended.  The previous versions of the protocol required that 3 
bottles of study medication be dispensed at each visit due to the short stability of the product 
once the bottles were opened.  New stability data has become available to allow the product to be 
used for 60 days after the bottle is opened.  This allows for less study medication to be dispensed 
between study visits.   
 
Version 5.0 amendment 4 dated 22 January 2019, has been amended to allow the investigator to 
perform the Investigator Global Assessment by comparing the current subject photos to the  to 
the baseline (Visit 2) photos.  The protocol was also amended to allow the subject to perform the 
Subject Self-Assessment by comparing the current subject photos to the  to the baseline (Visit 2) 
photographs.  This revision will enable both the investigator and subject to assess changes in hair 
growth over the duration of the study.

INTRODUCTION 
Aclaris Therapeutics, Inc. is developing ATI-50002 Topical Solution as topical treatment for alopecia 
areata (AA), alopecia totalis (AT), alopecia universalis (AU), androgenetic alopecia (AGA), and vitiligo.  
ATI-50002, the pharmacologically active metabolite of the orally administered ATI-50001, is a potent 
and highly selective inhibitor of Janus kinase 1 (JAK1) and Janus kinase 3 (JAK3)-dependent cytokine 
signaling, with minimal activity on JAK2- and Tyrosine kinase-2 (Tyk2)-dependent signaling. 
5.1. 
Overview of Androgenetic Alopecia 
Androgenetic alopecia is a hair loss disorder that affects both men and woman.  It is an 
extremely common disorder with relatively few treatment options.  There are only two FDA 
approved treatment options for men [Rogaine® (minoxidil) and Propecia® (finasteride)] and one 
FDA approved treatment for women (Rogaine®).   The disorder affects roughly 50% of men and 
perhaps as many women and the frequency increases with age in both men and women (Olsen E, 
et al., 2005) .  The pattern of hair loss is gradual in both men and women but the way in which 
the hair is lost differs.  Onset in men may begin any time after the onset of puberty and occurs in 
varying degrees in the bitemporal, frontal, mid scalp and vertex regions of the head (Olsen E, et 
al., 2005).  Woman with androgenetic alopecia experience diffuse thinning of the hair.   
Androgenetic alopecia can be an emotionally debilitating disease for both men and woman.    
5.2. 
Rationale for Using ATI-50002 to Treat AGA 
Recent studies in the laboratory of Dr. Angela Christiano (Columbia University; submitted) 
found that inhibition of JAK-STAT signaling initiates the hair cycle in normal mice and 
promotes hair growth in humans.  Particularly, in normal telogen phase, JAK signaling is 
elevated and is involved in maintaining quiescence of hair follicle stem cells.  Administering a 
JAK inhibitor results in initiating entry into anagen causing hair growth by inhibiting JAK-STAT 
signaling so that the hair follicle is no longer quiescent.  
Dr. Christiano’s laboratory further identified upstream factors that signal via the JAK-STAT 
pathway to promote hair growth.  Oncostatin M (OSM) is one such upstream factor.  OSM 
receptor (OSMR) is expressed on hair follicle stem cells, and all JAKs (JAK1, JAK2, JAK3, 
Tyk2) are activated by OSM.  Signaling from the JAKs is transduced by STATs, primarily via 
STAT5, in hair follicle keratinocytes.   
Unique anti-inflammatory macrophages, that are resident in the dermis near hair follicles, were 
identified as the source of OSM that promotes hair growth in the follicle.  These unique 
macrophages have been termed “trichophages” due to their having three distinct differences from 
typical M2-type macrophages.  Trichophages produce OSM during early and mid-telogen, which 
signals via JAK-STAT5 in hair follicle stem cells (HFSC) to inhibit proliferation and maintain 
hair follicle quiescence, particularly during second telogen.  These trichophages predominate 
during early and mid-telogen, and lose their OSM producing ability as telogen progresses, which 
allows the hair follicles (HFs) to enter the next anagen stage.   
Based on the above findings, as well as prior findings that administering recombinant OSM 
potently inhibits anagen (Yu, M.et al, 2008) Dr. Christiano anticipated that administering a

Version 5.0:   24 January 2019 
Amendment 4

JAK/STAT inhibitor should inhibit OSM signaling, initiate anagen and associated hair growth.  
Christiano’s laboratory has demonstrated this activity in a mouse mode of AGA. 
ATI-50002 is a JAK1/3 inhibitor with enzyme IC50 activities of 2nM and 36nM against JAK1 
and JAK3, respectively (data on file).  At a cellular/physiologic level, ATI-50002 inhibits 
interferon-γ-induced pSTAT1 activation with IC50 of 38nM (data on file).  The anticipated IC90 
concentration for pSTAT1 activation is approximately 0.4μM.  To expect ATI-50002 to inhibit 
JAK1/3-mediated pSTAT signaling, a significant excess of the inhibitor must be present in the 
target tissue.  The ability of the 0.46% ATI-50002 formulation to deliver ATI-50002 into the 
dermis was studied using a human skin permeation model. (Franz chamber with human skin).  
Resulting ATI-50002 concentrations were found to be in the range of 10-20μM in the dermis and 
epidermis.  A 10μM concentration represents a > 10X excess to the estimated IC90 for pSTAT 
inhibition.  The 0.46% ATI-50002 formulation is, therefore, anticipated to deliver sufficient drug 
to the epidermis and the dermis to inhibit JAK1/3 signaling and diminish immune-mediated 
inflammation.

INVESTIGATIONAL PLAN 
7.1. 
Overall Study Design 
This is an open-label phase 2 study designed to evaluate the safety and efficacy of ATI-50002 
Topical Solution, 0.46% in male and female subjects with androgenetic alopecia.  Subjects will 
be required to apply ATI-50002 study medication to their scalp twice a day for a total of 26 
weeks.  Subjects will have the option to consent to remain on study for an additional 26 weeks 
after Visit 10 is completed.  All subjects will be required to complete a safety follow up visit 4 
weeks after their last application of study medication.   
A total of 24 subjects (12 males and 12 females) ages 18-50 years of age with a clinical diagnosis 
of AGA will be enrolled in the study.  Male subjects must have a Norwood Hamilton 
classification of Type III vertex, IV or V and woman must have a Sinclair Grade of 2, 3 or 4.   
Subjects will be required to have a small 1.9 cm diameter circle clipped to ~ 1 mm in length on 
their balding scalp.  Subjects must also agree to have a dot tattoo applied in the center of the 
clipped area during Visit 2.     
Subjects will be required to complete the following treatment visits: 
Visit 1:  Screening (Day -14-0) 
Visit 2:  Day 1 
Visit 3:  Day 21 
Visit 4:  Day 28 
Visit 5:  Day 56 
Visit 6:  Day 84 
Visit 7:  Day 112 
Visit 8:  Day 140 
Visit 9:  Day 168 
Visit 10:  Day 182 
Subjects that consent to remain on study for an additional 6 months of treatment will have the 
following study visits: 
 
 
Visit 11:  Week 30 
 
 
Visit 12:  Week 35 
 
 
Visit 13:  Week 39

All subjects will be required to have a Follow up Safety Visit 4 weeks post last application of 
study medication.  
All protocol defined treatment assessments are outlined in Table 2 .   
7.2. 
Number of Subjects 
A total of 24 evaluable subjects will be enrolled to the study (12 male and 12 female) at 
approximately 3 investigational centers.   
7.3. 
Treatment Assignment 
This is an open label study.  All subjects will apply ATI-50002 Topical Solution 0.46% twice a 
day for 26 weeks followed by a 4 week follow up period.   
7.4. 
Criteria for Study Termination 
This study may be terminated prematurely in whole or in part due to a change in the benefit/risk 
profile for ATI-50002 Topical Solution such that continuation of the study would not be justified 
on medical or ethical grounds.  This determination may be made by the Study Investigators in 
conjunction with the Sponsor, or by IRB or the U.S. Food and Drug Administration (FDA).  The 
Sponsor may also elect to terminate the study if enrollment is sufficiently slow to prevent the 
completion of the study in an acceptable timeframe, or if ATI-50002 development is 
discontinued. 
If the study is terminated prematurely, the Sponsor will notify the Study Investigators and the 
FDA. The Investigator must promptly notify all enrolled subjects and the IRB of study 
termination.

7 The investigational study staff will be required to identify target area of the scalp that is located in an actively balding area.  Directions for proper hair clipping are outlined in 
Section 9.2 .  Sites will be required to apply a permanent dot tattoo to the subject’s scalp to identify the target hair area.   
8Global scalp photographs are to be performed at the screening visit.  If the photos are not of the appropriate quality, the site staff will perform a re-shoot at Visit 2.   
9 Canfield staff will review all global photographs within 2 days of the photographs being submitted.  If a re-take is required, Canfield will notify the site and the re-take 
photographs will need to be performed within 7 days of the visit.    
10 Canfield staff will review all macro photographs within 2 days of the photographs being submitted.  If a re-take is required, Canfield will notify the site and the re-take 
photographs will need to be performed within 7 days of the visit. 
11Sites will take the macro photographs and transmit these to Canfield in order for the Canfield scientists to perform the Target Area Hair Counts and the Target Area Hair Widths.  
The TAHC and TAHW will be entered into the Canfield database.   
12Sites will be required to review with each subject the proper application of the study medication and remind the subjects that they are only to wash their hair with the same 
shampoo/conditioner and maintain the same hair style throughout the study.    
13Subjects will be dispensed bottles of study medication at each monthly visit.  Study medication will be weighed prior to dispensing the medication to the subject and upon return 
of both used and unused bottles.  
14 Subjects that are not remaining on protocol therapy for an additional 6 months of treatment will not have study medication dispensed at Visit 10.  
All non-serious AEs will be collected from the time of first study medication application until the final study visit.  Serious AEs will be collected from the time of consent through 
the final study visit.   
15 Subjects that consent to remain on study for an additional 6 months of treatment will continue on study with Visit 11 (week 30) and then will have a final follow up Visit 4 
weeks after the last application of study medication in the 6-month extension part of the study.  Those subjects that do not consent to continuing on study medication for an 
additional 6 months will be required to have a final safety follow up visit conducted at week 30.  For those subjects that discontinue the study early, they must return to the clinic 4 
weeks following the last study medication application for a final safety visit.

TREATMENT OF SUBJECTS 
9.1. 
Hair Care During Study 
Subjects enrolled to the study must agree to use the same shampoo/conditioner through the 
course of the protocol therapy.  This information will be documented in the source notes and 
captured in the subject’s CRF.  Shampoo/Conditioner must not contain biotin, saw palmetto or 
tea tree oil (melaleuca oil).  Study medication must be applied to a dry scalp.  Subjects should 
not wash their hair for 6 hours after application of study medication.   Subjects are required to 
maintain the same hair style while on study.   
9.2. 
Target Area Hair Identification  
In order to assess the efficacy of the study medication, a 1 cm2 area of the subject’s scalp will be 
identified and be used to count the number of hair follicles that appear in the area throughout the 
duration of the study treatment period.   
Using the Canfield supplied clear plastic template, a 1 cm2 area will be identified in an actively 
balding area.  The hair will be pulled through the circular area of the plastic template and then 
the hair will be clipped short using the supplied electric hair clippers.  After the hair is clipped, 
the template is to be removed and the hairs are to be further trimmed to approximately 1mm in 
length using 4- inch curved scissors.  Once the target area is identified and the hair is clipped 
then a small tattoo will be applied to mark the target area.  Refer to Section 9.4  regarding the 
procedure for the scalp tattoo.   This target area will be used for each TAHC/TAHW assessment 
throughout the study.

Preparation of Subjects Scalp for Global and Macro Photographs 
Investigational sites are to perform the global photographs prior to performing the macro 
photographs.   
For all vertex global scalp photographs (male subjects only), the subject’s hair is to be combed 
outwards from the vertex like the spokes of a wheel.  For all frontal global scalp photographs 


Protocol: ATI-50002-AGA-201 
Version 5.0:  24 January 2019 
  
Amendment 4

(male and female subjects), the subject’s hair is to be parted in the center and the hair is to be 
combed away from the center part.   
The global photographs will be used by the investigator to perform the Investigative Global 
Assessment (IGA) and by subject to perform the Subject Self-Assessment (SSA).  Refer to 
Section 11.3 . 
9.4. 
Scalp Tattoo 
At Visit 2 all subjects will be required to have a permanent dot tattoo applied to their scalp in an 
actively balding area.  The tattoo will mark the center of the identified target area from which the 
macro photographs and TAHC and TAHW will be performed.   
All sites will be supplied with a tattoo machine and the necessary ink to apply the tattoo.  The 
tattoo machines will be supplied by Canfield and sites will be provided with instructions on how 
to prepare the machine and the subject’s scalp to ensure that the tattoo is applied appropriately.   
9.5. 
Application of Study Medication  
 
Subjects will be instructed to apply a thin film of ATI-50002 Topical Solution 0.46% (up to 4-
mL), twice-daily; once in the morning and approximately 12 hours later to the balding area of the 
clean dry scalp.  Refer to Appendix 1  for the complete application instructions.   The subject 
must wash her/his hands thoroughly before and after each study drug application. Investigational 
site staff will dispense a month’s supply of study medication along with disposable droppers to 
the subject at each study visit.  Study medication bottles will be weighed by the site staff at the 
time of dispensing and when the bottles are returned.  Subjects are to return used and unused 
study medication at each study visit.  The disposable droppers should be disposed of at the 
subject’s home. 
At each study visit, the study staff will review the study medication instructions and proper 
application technique. (Appendix 1 ) with the subject.  During Visit 2, the subject will apply the 
first dose of study medication in the office under the instruction and supervision of the study 
staff.   
During each site visit, the study staff member will: 
• Dispense study medication bottles to the subject. 
• Instruct the subject on the appropriate application technique following instructions in 
Appendix 1. 
• Weigh the bottles prior to dispensing the study medication 
• Observe the subject’s first study medication application to ensure proper coverage and 
monitor the subject for at least 20 minutes (Visit 2 only).   
   
All used study medication bottles will be weighed by the investigational site at each visit.

9.6. 
Concomitant Medications 
Concomitant therapies are any new or existing therapy received from Visit 1 until discharge from 
the study. 
Concomitant therapies include drug (e.g., prescription, over-the-counter [OTC]) and non-drug 
(e.g., chiropractic, physical therapy, energy-based treatments) therapies. Subjects will refrain 
from receipt of any therapy in compliance with the inclusion/exclusion criteria. Subjects should 
refrain from changing the use of any concomitant therapies during the study. 
All new or modified concomitant therapies used during the study must be recorded in the 
subject’s eCRF. 
9.7. 
Prohibited Medications 
The following medications will be prohibited from being used while the subject is on study and 
for the identified time-frame prior to Visit 2: 
• 
Scalp hair growth promoting products (e.g.minoxidil, finasteride, dutasteride, saw palmetto) for 6 
months prior to Visit 2. 
• 
Anti-androgenetic therapies (e.g. spironolactone, flutamide, cyproterone acetate) for 6 months prior 
to Visit 2.   
• 
Hair transplantation or hair weaving within 6 months of Visit 2. 
•

ASSESSMENT OF EFFICACY 
11.1. 
Target Area Hair Count (TAHC) and Target Area Hair Width 
(TAHW) 
The primary efficacy endpoint of the study is the change from baseline in non-vellus (TAHC 
(hairs/cm2) and one of the secondary efficacy endpoints is the change from baseline in the 
cumulative TAHW.  The subject’s identified target area will be assessed for TAHC and TAHW 
by the Canfield trained and validated image analysis technicians who are blinded to the 
center/subject/visit/treatment information.  Canfield Scientific, Inc. will supply all investigational 
sites with photography equipment, tattoo equipment, computer based scanners imaging software, 
and printers required to capture all global and macro photographs.  
As described in Section 8.4, all subjects will be required to have a small permanent tattoo applied 
to their scalp to mark the center of the identified target area.  Global and macrophotographs will 
be taken by the investigational study staff in accordance with the schedule of assessments.  Refer 
to Table 2 and Table 3 .     
The Canfield supplied VEOS SLR camera will be used to take the macrophotographs of the 
subject’s scalp.  These images will be transmitted to Canfield for analysis using a computer 
assisted technique to assess the TAHC and TAHW.   
Study staff will receive training from Canfield on the use of the photography equipment, 
scanners and imaging software in order to transmit all imaging data to Canfield.   
11.2. 
Norwood-Hamilton and Sinclair Scales  
Treating investigators will be required to rate the subject’s level of hair loss at baseline based on 
the Norwood Hamilton Scale for male subjects and the Sinclair scale for women.  In addition, at 
the protocol defined time-points, the Investigator will be required to use the appropriate scale to 
assess the change in hair growth in both male and female subjects.   
11.3. 
Investigator Global Assessment and Subject Self-Assessment 
Global photographs will be taken of the vertex scalp of male subjects and of the frontal scalp of 
both male and female subjects.  These global scalp photographs will be used by the investigator 
and the subject to rate the subject’s amount of hair growth at each protocol defined time-point.   
After the global photographs are taken the investigator and the subject will use the current photos 
to rate the change in hair growth from the baseline visit (Visit 2). Both the investigator and the 
subject will record their assessment into the Canfield computer system.  The following 7-point 
rating scale will be used:

ASSESSMENT OF SAFETY 
12.1. 
Safety Parameters 
Safety will be assessed throughout the study by the investigator or a designated and appropriately 
trained staff member. 
12.1.1. 
Demographic/Medical History 
During the screening visit (Visit 1), the investigator or designee will interview each subject to 
obtain demographic information including date of birth, sex at birth, Fitzpatrick skin type, race 
and, if appropriate, ethnicity. The investigator or designee will interview each subject to obtain 
medical history information related to all medical conditions, surgeries and disease states that, at 
screening: are ongoing, require concomitant therapy or are, in the opinion of the investigator, 
relevant to the subject’s study participation.  In addition, the medical history of women who are 
not of childbearing potential should reflect the reason e.g. post-menopausal for 1 year or greater, 
total hysterectomy.  Information regarding the subject’s prior treatments or therapies related to 
AGA must be documented along with the type of shampoo/conditioner the subject will use 
during the study.   
12.1.2. 
Vital Signs 
Vital signs will be measured at each visit during the study. The following items will be 
measured: 
• Body temperature 
• Pulse rate 
• Respiration rate 
• Blood pressure (systolic and diastolic) after the subject sits quietly for at least 5 minutes 
• Height (at Visit 2 only) 
• Weight (at Visit 2 only) 
Any measure that is, in the opinion of the investigator, abnormal AND clinically significant (CS) 
must be recorded as history if found prior to the first study medication application, or as an AE if 
found after the first study medication application begins. 
12.1.3. 
Physical Examination 
The investigator or designee will perform a physical examination for all body systems (general 
appearance, examination of head, eyes, ears, nose and throat, respiratory, cardiovascular, 
abdominal, neurological, musculoskeletal, lymphatic and skin assessment) at Baseline (Visit 2) 
and end of study Week 30 (Visit 11) 
12.1.4. 
Electrocardiogram (ECG) 
Standard 12-lead ECGs will be performed by a qualified staff member at Screening (Visit 1), 
Visit 4 (Day 28) Visit 10 (Day 182) and Visit 11/Safety Follow up.  The ECGs must be obtained 


Protocol: ATI-50002-AGA-201 
Version 5.0:  24 January 2019 
  
Amendment 4 
 
45 
 
 
  
 
using a standard 12-lead ECG with a 10mm/mV amplitude, at 25mm/sec and a 5-10-second 
duration. To ensure a steady heart rate the subject must rest quietly in the supine position for at 
least 5 minutes prior to performing the ECG. 
A central cardiology laboratory will provide ECG equipment, supplies and site training.  In 
addition, the central cardiology laboratory will process ECGs received by the sites and report 
results via a secure study portal.  The ECG results will be interpreted by a qualified health 
professional (evaluator) and the interpretation reported either directly on the tracing or in a 
separate report.   The evaluator will interpret the results of every ECG and define the ECG as 
“normal” or “abnormal”.  Variations such as minor ST changes (i.e., <0.5mm depression) and 
early re-polarization are considered normal. 
The investigator must review the evaluator’s interpretation of each subject’s screening ECG prior 
to Baseline (Visit 2). The investigator will review the evaluator’s interpretation of all ECG 
reports in a timely manner and comment on the clinical relevance of any result that is defined by 
the evaluator as abnormal. 
Any abnormalities that are, in the opinion of the investigator, clinically significant, must be 
reported as history if found prior to the start of the first study medication application or as an AE 
if found after the start of the first study medication application.   
If a subject’s ECG results meets the ECG withdrawal criteria that is outlined in section 7.3, the 
site staff must discontinue the subject from study medication and perform all protocol required 
assessments at the early termination/follow up visit.   
12.1.5. 
Pregnancy Tests 
Subjects who are WOCBP must have a negative serum pregnancy test result at Screening (Visit 
1) to continue in the study, and a negative UPT at Baseline (Visit 2) prior to study entry.  If the 
result of any post-treatment urine pregnancy test is positive, the subject will be withdrawn from 
the study and the subject’s pregnancy documented and followed.  In addition, the investigator or 
designee will perform a urine pregnancy test for subjects who are WOCBP at monthly visits 
during the study. 
12.1.6. 
Local Skin Reactions 
Investigators and subjects will be required to assess the treated scalp area for local skin reactions 
(LSRs) at visits 2-11.  The following signs and symptoms of contact dermatitis will be assessed: 
• Stinging/Burning 
• Itching 
• Dryness 
• Erythema 
• Scaling 
The Investigator and Subject should report the one integer that best describes the severity of each LSR 
sign or LSR symptom for the treated scalp area using the scale below.

All subjects will be required to have a QuantiFERON TB blood test performed at screening to 
assess for exposure to the tuberculosis virus.  At Visit 1 (Screening) a blood sample will be 
drawn and sent to a central laboratory for analysis.  Subjects that test positive will not be eligible 
for enrollment to the study. 
12.2. 
Adverse and Serious Adverse Events 
12.2.1. 
Definition of Adverse Events 
12.2.1.1. Adverse Event (AE) 
An AE is the development of an undesirable medical condition or the deterioration of a pre-
existing medical condition following or during exposure to a pharmaceutical product, whether or 
not considered casually related to the product.  In clinical studies, an AE can include an 
undesirable medical condition occurring at any time, including baseline or washout periods, even 
if no study treatment has been administered. 
The investigator should, when certain, report a diagnosis rather than the signs, symptoms or 
clinically significant abnormal laboratory values associated with the AE. Otherwise, signs, 
symptoms or abnormal laboratory values may be used to describe the AE. 


Protocol: ATI-50002-AGA-201 
Version 5.0:  24 January 2019 
  
Amendment 4 
 
48 
 
 
  
 
Any CS abnormality discovered prior to the first study medication treatment should be reported 
as medical history, not as an AE. 
All AEs that occur from the time of first study medication application (V2) until 30 days after 
last study medication application must be documented in the subject’s source documents and in 
the Aclaris’ electronic data capture system.   
12.2.1.2. Serious Adverse Event (SAE) 
A serious adverse event is an AE occurring during any study phase (ie, baseline, treatment, 
washout, or follow-up), and at any dose of the investigational product, comparator or placebo, 
that fulfils one or more of the following: 
• Results in death 
• It is immediately life-threatening 
• It requires in-patient hospitalization or prolongation of existing hospitalization 
• It results in persistent or significant disability or incapacity 
• Results in a congenital abnormality or birth defect 
• It is an important medical event that may jeopardize the patient or may require medical 
intervention to prevent one of the outcomes listed above. 
The term “life threatening” refers to an event in which the subject was at risk of death at the time 
of event; it does not refer to an event that hypothetically might have caused death if it were more 
severe. 
Important medical events are those that may not be immediately life threatening, result in death 
or hospitalization, but are clearly of major clinical significance and may jeopardize the subject or 
require intervention to prevent one of the outcomes listed in the SAE definition above. These 
should also usually be considered serious. 
SAEs will be reported from the time of informed consent until 30 days past last application of 
study medication, whether or not they are related to the study.  SAEs will be documented on the 
Aclaris SAE report form and in the eCRF.    
12.2.1.3. Unexpected adverse event 
An AE is considered unexpected if it is not listed in the Investigator Brochure or is not listed at 
the specificity or severity that has been observed. 
12.3. 
Recording Adverse Events 
12.3.1. 
Adverse event reporting period 
The investigator must start reporting non-serious AEs with the subject’s first study medication 
application and continue reporting until the end of the subject’s last study visit. Reporting for 
SAEs must start when the subject signs the ICF and continue until the end of the subject’s last 
visit. 


Protocol: ATI-50002-AGA-201 
Version 5.0:  24 January 2019 
  
Amendment 4 
 
49 
 
 
  
 
12.3.2. 
Severity 
The investigator is to define the severity of each AE using the following definitions as a 
guideline. The investigator will consider the range of the possible severity of the event and 
identify the severity that is the most appropriate according to her/his medical judgment. 
Mild – Awareness of signs or symptom, but easily tolerated. 
Moderate – Discomfort, enough to cause interference with usual activity. 
Severe – Incapacitating with inability to perform usual activity. 
12.3.3. 
Relationship to study medication 
The investigator will determine if there is a reasonable causal relationship between the study 
medication and an AE or not. The investigator will use her/his best medical judgment and 
consider all relevant factors (e.g., temporal relationship, location of the event, the subject’s 
relevant medical history, concomitant therapies and concurrent conditions) to determine the 
relationship of the AE to the study medication. The investigator will define the relationship of an 
AE to the study medication by selecting one of the following categories: 
Related – There is a reasonable causal relationship between the study medication and the 
AE. 
Not Related – There is not a reasonable causal relationship between the study medication 
and the AE. 
The expression “reasonable causal relationship” is meant to convey in general that there are facts 
(evidence) or arguments to suggest a causal relationship (International Conference on 
Harmonization [ICH] E2A). 
12.3.4. 
Procedures for reporting adverse events 
At each post-enrollment visit, the investigator will question the subject to elicit AEs using a non-
directive question such as “Has there been any change in your health since the previous study 
visit?”  If appropriate, based on the subject’s response to non-directed questioning to elicit AEs, 
the investigator will follow-up with directed questions and appropriate evaluations. 
Any AE noted during the reporting period must be reported in the source documents and on the 
appropriate AE eCRF. AEs that are defined as “Not Related” to the study medications will be 
followed until they are resolved or until the subject’s last study visit. AEs that are defined as 
“Related” to the study medications will be followed until they are resolved or, if not resolved at 
the subject’s last study visit, until in the opinion of the investigator, the AE reaches a clinically 
stable outcome with or without sequelae. 
Should a pregnancy occur, it must be reported and recorded on Aclaris’s pregnancy form.  
Pregnancy in itself is not regarded as an AE unless there is a suspicion that an investigational 
product may have interfered with the effectiveness of a contraceptive medication. 
The outcome of all pregnancies (spontaneous miscarriage, elective termination, normal birth or 
congenital abnormality) must be followed up and documented even if the patient was 
discontinued from the study. 


Protocol: ATI-50002-AGA-201 
Version 5.0:  24 January 2019 
  
Amendment 4 
 
50 
 
 
  
 
All reports of congenital abnormalities/birth defects are SAEs.  Spontaneous miscarriages should 
also be reported and handled as SAEs.  Elective abortions without complications should not be 
handled as AEs. 
12.3.5. 
Procedure for reporting a serious adverse event 
Upon becoming aware of a SAE occurring during the SAE reporting period (time of subject 
consent until the end of the subject’s last visit), whether or not related to the study medications, 
the investigator must: 
1. Take the appropriate medical action to ensure the subject’s safety. 
2. Immediately inform the Safety Monitor of the SAE by email, ensuring that the subject 
information is deidentified (only subject initials and subject number) to: ProPharma, 
Email: clinicalsafety@propharmagroup.com. 
3. Print a copy of the email confirmation from ProPharma and place in the study file. 
4. Within 24-hours complete, as fully as possible, an AE eCRF and an SAE form; e-mail the 
forms and any other relevant information (e.g., concomitant medication eCRF, medical 
history eCRF, laboratory test results) to ProPharma (Aclaris Therapeutics, Inc. Safety 
Monitor). 
5. Monitor and document the progress of the SAE until it resolves or, if not resolved after 
the subject’s last study visit, until in the opinion of the investigator the AE reaches a 
clinically stable outcome with or without sequelae AND the investigator and Aclaris 
Therapeutics, Inc.  Safety and Medical Monitor agree that the SAE is satisfactorily 
resolved. 
6. Inform the Aclaris Therapeutics, Inc. Safety Monitor of SAE updates, via telephone, 
followed by an SAE form update sent by e-mail. 
Comply with the appropriate regulatory requirements and Aclaris Therapeutics, Inc. instructions 
regarding reporting of the SAE to the responsible Institutional Review Board (IRB) or Ethics 
Committee (EC). 
12.4. 
Pregnancy 
12.4.1. 
Definition of Women of Child Bearing Potential (WOCBP) 
WOCBP includes any female who has experienced menarche and who has not undergone 
successful surgical sterilization (e.g., hysterectomy, bilateral tubal ligation, or bilateral 
oophorectomy) or is not postmenopausal. Postmenopausal is defined as ≥12 months with no 
menses without an alternative medical cause.  WOCBP must have a negative serum pregnancy 
test at screening and a negative UPT at baseline prior to randomization. 
12.4.2. 
Highly Effective Methods of Birth Control 
The Investigator or sub-investigator will discuss the potential risk factors associated with 
pregnancy and the importance of maintaining a highly effective method of contraception 
throughout the study with all WOCBP (for example, those which result in a low failure rate - i.e., 
less than 1% per year- when used consistently and correctly).  All WOCBP must use a highly 


Protocol: ATI-50002-AGA-201 
Version 5.0:  24 January 2019 
  
Amendment 4 
 
51 
 
 
  
 
effective method of birth control during the study and for 30 days after the final application of 
study medication in a manner such that risk of failure is minimized.   
Highly effective methods include: 
• Combined (estrogen and progestogen containing) hormonal contraception associated with 
inhibition of ovulation: 
o oral 
o intravaginal 
o transdermal 
• Progestogen-only hormonal contraception associated with inhibition of ovulation: 
o oral 
o injectable 
o implantable 
• intrauterine device (IUD) 
• intrauterine hormone-releasing system (IUS) 
• vasectomized partner1 
• sexual abstinence2 
1Vasectomized partner is a highly effective birth control method provided that partner is the sole sexual partner 
of the WOCBP trial participant and that the vasectomized partner has received medical assessment of the 
surgical success.  
2 Sexual abstinence is considered a highly effective method only if defined as refraining from heterosexual 
intercourse during the entire period of risk associated with the study treatments. The reliability of sexual 
abstinence needs to be evaluated in relation to the duration of the clinical trial and the preferred and usual 
lifestyle of the subject. 
 
WOCBP must be on a highly effective method of birth control for the following timeframes prior 
to study entry:  
• Implants (on a stable dose for ≥90 days) 
• Injectables (on a stable dose for ≥90 days) 
• Patches (on a stable dose for ≥90 days) 
• Combined oral contraceptives (on a stable dose for ≥90 days) 
• Intrauterine devices (inserted for ≥30 days). 
 
Prior to trial enrollment, WOCBP must be advised of the importance of avoiding pregnancy 
during trial participation and of the potential risk factors associated with pregnancy while in the 
study.  The subject must sign an informed consent form documenting this discussion.  During the 
trial, all WOCBP will be instructed to contact the investigator immediately if they suspect they 
might be pregnant (e.g., missed or late menstrual period). 
 


Protocol: ATI-50002-AGA-201 
Version 5.0:  24 January 2019 
  
Amendment 4 
 
52 
 
 
  
 
If a subject or investigator suspects that the subject may be pregnant prior to study medication 
administration, the study medication must be withheld until the results of a pregnancy test are 
available.  If pregnancy is confirmed, the subject must not receive study medication and must be 
discharged from the study.  
 
If, following study medication administration, it is determined that the subject may have been or 
was pregnant at the time of study medication exposure (including at least 2 days after study 
medication administration) the investigator must immediately notify the Aclaris Therapeutics, 
Inc. Medical Monitor and record the event on a pregnancy surveillance form. While not an AE or 
SAE, the investigator must report every pregnancy using a pregnancy surveillance form and 
follow the reporting procedures described for SAE reporting. 
Protocol-required procedures for trial discontinuation and follow-up must be performed on the 
subject unless contraindicated by pregnancy (e.g., x-ray studies). Other appropriate pregnancy 
follow-up procedures should be considered if indicated. In addition, the investigator must report 
to Aclaris Therapeutics, Inc.’s Medical Monitor on the pregnancy surveillance form, follow-up 
information regarding the course of the pregnancy, including perinatal and neonatal outcome. 
Infants should be followed for a minimum of six weeks. 
 
12.5. 
Protocol Deviation and Protocol Violations 
A protocol deviation is defined as an accidental or unintentional change to, or non-compliance 
with the research protocol that does not increase risk, or decrease benefit or; does not have a 
significant effect on the subject’s right, safety, or welfare; and/or on the integrity of the data.  
Deviations may result from the action of the subject, researcher or research staff.  A protocol 
deviation does not involve inclusion/exclusion criteria. 
A protocol violation is defined as an accidental or unintentional change to, or non-compliance 
with the IRB approved protocol without prior sponsor approval.  Protocol violations generally 
increase risk or decrease benefit, affects the subject’s rights, safety, or welfare, or the integrity of 
the data.

STATISTICS 
13.1. 
Statistical Methods 
Summary descriptive statistics (N, mean, median, SD) by visit will be provided for all safety and 
efficacy parameters. The Intent to Treat population will be used for all efficacy assessments and 
the Safety population will be used for all safety assessments. No data imputation will be used.  
Primary and secondary efficacy parameters are described in the sections below. 
13.2. 
Primary Efficacy Endpoint 
Mean change from baseline in non-vellus TAHC will be quantified using a microphotographic 
technique and calculated along with the median, standard deviation, standard error, and 95% 
confidence limits around each mean change to allow tests of the null hypothesis that the 
population mean changes are zero. 
13.3. 
Secondary Efficacy Endpoints 
Mean change from baseline in cumulative TAHW will be quantified using a microphotographic 
technique and calculated along with the median, standard deviation, standard error, and 95% 
confidence limits around each mean change to allow tests of the null hypothesis that the 
population mean changes are zero. 
The seven-point rating scale to measure the investigator and subject assessment of the 
development of new hair growth/scalp coverage will be analyzed with summary statistics (N, 
mean, median, SD) for each visit where the assessment is made.  Similar summary statistics will 
be used to analyze change from baseline in AGA stage separately for males (Horwood Hamilton 
Scale) and for females (Sinclair Scale) at each applicable visit. 
13.4. 
Safety Assessments 
Data from all enrolled and treated subjects will be presented and summarized. Safety analyses 
will include descriptive statistics calculated on the safety parameters using the safety population. 
The proportion of subjects with treatment-emergent adverse events will be tabulated and 
presented by Medical Dictionary for Regulatory Activities (MedDRA) System Organ Class. 
Vital signs and clinically significant abnormal laboratory results will also be tabulated and 
presented.  Clinical laboratory and ECG results will be tabulated.

Study Monitoring 
Before an investigational site can enter a patient into the study, a representative of Aclaris 
Therapeutics will visit the investigational study site to: 
• Determine the adequacy of the facilities. 
• Discuss with the investigator(s) and other personnel their responsibilities with regard to 
protocol adherence, and the responsibilities of Aclaris Therapeutics, Inc. or its 
representatives.  This will be documented in a Clinical Study Agreement between Aclaris 
Therapeutics, Inc. and the investigator. 
During the study, a monitor from Aclaris Therapeutics, Inc. or representative will have regular 
contacts with the investigational site, for the following: 
• Provide information and support to the investigator(s). 
• Confirm that facilities remain acceptable. 
• Confirm that the investigational team is adhering to the protocol, that data are being 
accurately recorded in the case report forms, and that investigational product 
accountability checks are being performed. 
• Perform source data verification.  This includes a comparison of the data in the case 
report forms with the patient’s medical records at the hospital or practice, and other 
records relevant to the study.  This will require direct access to all original records for 
each patient (e.g. clinic charts). 
• Record and report any protocol deviations not previously sent to Aclaris Therapeutics, 
Inc. 
• Confirm AEs and SAEs have been properly documented on CRFs and confirm any SAEs 
have been forwarded to ProPharma and those SAEs that met criteria for reporting have 
been forwarded to the IRB.

APPENDIX 1. SUBJECT INSTRUCTIONS FOR STUDY MEDICATION 
APPLICATION TO THE SCALP 
Preparation and General Instructions:  
 
1. Gather a clean washcloth and towel, the study medication bottle, and disposable dropper. 
2. Scalp should be clean (free of hair styling products), and dry or at least towel-dried 
before applying study medication.  Ensure that your scalp is as dry as possible.  A clean 
scalp will allow the study medication to penetrate down into the scalp to ensure you are 
getting the best application.   
3. Subjects are to wash their hair using a non-medicated shampoo [not containing biotin, 
saw palmetto or tea tree oil (melaleuca oil)] during the treatment period (26 weeks).  
4. Subjects are not to wash their hair or participate in strenuous exercise that would cause 
profuse sweating for 6 hours after application of study medication.       
5. Wash your hands with soap and water before and after using this study medication.  
6. You will apply a thin layer of study medication to the identified area of the scalp as 
instructed by the study doctor or the study staff.  Keep applying study medication to the 
area of hair loss throughout the study, even if scalp hair is re-growing in these areas. 
7. The amount of study medication you will apply during one treatment is a total of up 
to 4ml (1 ml droppers supplied with study medication).   
8. Avoid study medication contact with the eye.  If the study medication gets on any part of 
your body other than your scalp, rinse the area well with water.  
9. You will apply study medication twice-a-day, approximately 12 hours apart.   
10. Remember to bring your study medication bottles both used and unused to each study 
visit. 
 
Study Medication Application: 
1. Draw up exactly 1 mL of study medication into the dropper. The medication level should 
be at the 1mL line.  
2. During study medication application, avoid any study medication running into your eyes.   
3. Squeeze a few drops of study medication onto the center of the identified area of your 
scalp and gently rub the study medication into your scalp. Keep applying a few drops and 
rubbing into your scalp until the entire area is covered with a thin film of study 
medication.    
4. Draw up additional medication - 1 mL at a time- to cover the entire area on your scalp 
with hair loss.   
5. Replace the screw top cap and make sure it is closed tightly.  Dispose of the used 
dropper(s). 
6. It is important to continue to apply study medication to the areas of hair loss throughout 
the study, even if there is hair growth in the area(s).

7. Wash your hands after using this product to prevent any residue being left on your hands. 
8. Allow the study medication to dry for at least 15 minutes before you apply any styling 
products to the hair.  All topical products applied to the hair and scalp must be reviewed 
and approved by your study doctor before use. 
9. If you missed a dose or doses, tell the study staff at your next visit.     
10. Do not wash your hair or scalp for at least 6 hours after applying study medication.  
Missed Doses: If you miss a dose of this study medicine, apply it as soon as possible. However, 
if it is almost time for your next dose, skip the missed dose, and go back to your regular dosing 
schedule. 
Storage: Store the medicine in the original glass bottle in the carton provided at room 
temperature, away from heat, moisture, and direct light. Keep from freezing.  Keep out of the

APPENDIX 2. NORWOOD HAMILTON SCALE 
 
 
 
(Gupta M and Mysor V, 2016) 
Type I:  Minimal or no recession of the hairline 
Type II:  Triangular, usually symmetrical, areas of recession at the frontotemporal hairline 
Type III:  Deep symmetrical recession at the temples that are bare or only sparsely covered by 
hair.  In Type III vertex, the hair loss is primarily from the vertex with limited recession of the 
frontotemporal hairline that does not exceed the degree of recession seen in Type III. 
Type IV:  Frontotemporal recession is more severe than in Type III and there is sparse hair or no 
hair on the vertex.  The two areas of hair loss are separated by a band of moderately dense hair 
that extends across the top.  The is band connects with the fully haired fringe on the sides of the 
scalp. 


Protocol: ATI-50002-AGA-201 
Version 5.0:  24 January 2019 
  
Amendment 4 
 
64 
 
 
  
 
Type V:  The vertex hair loss region is still separated from the frontotemporal region but it is less 
distinct.  The band of hair across the crown is narrower and sparser and the vertex and 
frontotemporal regions of hair loss are bigger. 
Type VI:  The bridge of hair that crosses the crown is gone with only sparse hair remaining.  The 
frontotemporal and vertex regions are joined together and the extent of hair loss is greater.   
Type VII:  The most severe form of hair loss and only a narrow band of hair in a horseshoe shape 
remains on the sides and back of the scalp.  This hair is usually not dense and may be quite fine.

Image Capture Procedures: 
 
1. The supplied equipment is to be used exclusively for this study. Modifications, 
adjustments or repairs of the camera equipment are not to be undertaken without the 
expressed instruction of Canfield Scientific, Inc. 
 
2. Prior to capturing the subject photographs, Site Photographer launches Canfield 
Capture software by selecting the icon from the laptop desktop.   
 
3. Site Photographer logs in using unique Username/Password and selects study 
protocol. 
 
4. Site Photographer either creates a New Subject for an initial visit or, for a return 
subject, highlights the appropriate existing Subject ID listed in the Canfield Capture 
database.  The visit name (as per Section IV above) is selected by Site Photographer 
and the photo date is captured by the software. 
 
5. Site Photographer follows the application software prompts to make the capture set. 
The capture set consists of the vertex view of the head/scalp. 
 
6. Vertex View Hair Preparation: The hair has to be clean, dry, and combed out radially 
from the vertex like the spokes of a wheel. The blue drape cloth has to be placed over 
the subject’s shoulders to mask the shirt and collar color.   
 
7. For each photograph captured in the Screening capture sequence, the photographer 
matches orientation to the reference diagrams in Canfield Capture while utilizing the 
live-preview available.  At the Follow-Up sessions, the live-preview with image 
overlay/ghosting helps maintain photo consistency i.e. magnification and head 
positioning relative to the camera.  
 
VI. 
Image Transfer Procedure: 
1. After each capture, Site Photographer is prompted to review the photograph for 
acceptability.  The Site Photographer either accepts the photograph and moves on to

Version 5.0:  24 January 2019 
  
Amendment 4 
 
68 
 
 
  
 
the next capture or does not accept it and recaptures.  
2. Following the session, the Photographer submits the photographs to Canfield. Upon 
exiting, the software automatically reads, checksums, encrypts, packages, and 
duplicates the data to submit to Canfield via internet or removable media submission.   
3. Modes of image transfer: 
• 
Internet:  A secure, validated, compliant web server set up at Canfield is used for 
secure transfer of study photographs by study sites.  Photographs are to be 
transferred the day of capture.

On the digital images, a circular 1-cm2 target area is identified using the landmark dot 
tattoo placed in the center of the circle of clipped hairs as a reference point.  From the 
identified 1- cm2 target area, the width of each hair is determined using an electronic 
caliber measurement.  All hairs >30 µm are classified as terminal hairs.  
 
Hair image analysis is randomized and blinded; subject identity and photographic 
sequence is unknown to the Canfield technicians conducting the image analysis. 
 
Parameters derived from hair measurement analysis include: 
 
• 
Target Area Haircount (TAHC) 
• 
Target Area Hair Width (TAHW)
