Brief summary:
This study determines the Maximum Tolerable Dose (MTD) by maximum BSA percentage treated and evaluates safety and efficacy of 1.1% w/w AMTX-100 CF versus placebo (vehicle).

The study has two parts:

Phase I (Part 1):

Approximately Twenty-five (25) subjects with various treatable Body Surface Area (BSA) involvement of Mild to Moderate Atopic Dermatitis will be enrolled in the study and treated with 1.1% w/w AMTX-100 CF.

Phase II (Part 2):

Approximately sixty (60) subjects with Mild to Moderate Atopic Dermatitis with various treatable BSA involvement of Mild to Moderate Atopic Dermatitis will be randomized to be treated with 1.1% w/w AMTX-100 CF3 concentration or Vehicle (Placebo) in the study.

Detailed description:
AMTX-100 CF3 drug product is formulated as a water-based, topical cream incorporating a 28-amino acid synthetic polypeptide (AMTX-100) as the active pharmaceutical ingredient (API). AMTX-100 is a chimeric, cell-penetrating, bifunctional nuclear transport modifier (NTM), that is engineered to modulate nuclear transport of transcription factors (NF-κB, NFAT, AP-1, and STAT1) involved in the activation of gene expression of key mediators of inflammation (TNFα, IL-1β, IL-6, IL-17, MCP-1, etc.) and metabolic syndrome (ChREBP and SREBP) by importin α/β complex and importin β, respectively. This further leads to a reduction in pro-inflammatory cytokine/chemokine production and lipid and carbohydrate metabolic products.

AMTX-100 CF3 is intended to improve symptoms associated with mild to moderate Atopic Dermatitis in adults. This Phase I/II study aims to determine the Maximum Tolerable Dose (MTD) by maximum BSA percentage treated and to evaluate efficacy of 1.1% w/w AMTX-100 CF3 versus placebo (vehicle).

Arms: arm 1: Open-label, five (5) cohorts were sequentially enrolled. AMTX-100 CF 1.1% w/w, topically applied twice a day for 7 consecutive days to all treatable AD affected areas from 3% to 70% of the Body Surface Area (BSA) (3% BSA ≤ AD Affected Area ≤ 70% BSA) arm 2: AMTX-100 CF3 (1.1% w/w), topically applied twice a day for 28 consecutive days to all treatable AD affected areas arm 3: Placebo (Vehicle) (0% w/w), topically applied twice a day for 28 consecutive days to all treatable AD affected areas
Interventions: intervention 1: 1.1% w/w AMTX-100 CF-part1 intervention 2: Placebo intervention 3: 1.1% w/w AMTX-100 CF3-part2
Intervention descriptions: intervention 1: AMTX-100 CF, topical cream with 1.1% w/w active pharmaceutical ingredient intervention 2: Topical cream manufactured to mimic AMTX-100 CF3 intervention 3: AMTX-100 CF3, topical cream with 1.1% w/w active pharmaceutical ingredient

PROTOCOL DESIGN 
2.1 
Design Overview 
This is an adaptive, Phase I study: Part 1 (Maximum Tolerable Dose (MTD) Finding by maximum 
percentage of BSA treated).  
Part 1 of this study is an open-label, dose escalation study of the safety and tolerability of topically 
applied AMTX-100 CF in adult patients with mild to moderate AD. Part I of this study is designed 
to determine the MTD of AMTX-100 CF (1.1% w/w concentration) for the highest treated percentage 
of the BSA affected with AD. The MTD is defined as 1 cohort dose level below the dose, in which 
dose limiting toxicities (DLTs) as defined below were observed. In total, five (5) cohort dose levels 
will be tested sequentially by escalating applications of AMTX-100 CF 1.1% to higher percentages 
of BSA affected with AD at each cohort. Each enrolled subject will receive the assigned dose of 
Open-label AMTX-100 CF 1.1% w/w to be applied twice daily to all treatable lesions of AD

Assuming no DLTs occur at any cohorts, in Part 2 (Phase II) of the study, three dose concentrations 
(low doset-treatment safety. concentration (0.11% w/w), medium dose concentration (0.33% w/w) 
and high dose concentration (1.1% w/w)) of AMTX-100 CF will be further evaluated for safety and 
efficacy, compared to placebo (vehicle), in adult patients with mild to moderate AD, with up to 70% 
treatable BSA involvement.

What is the purpose of the study? 
 
Your study doctor and his/her colleagues are conducting a research study with Amytrx 
Therapeutics, Inc. (Amytrx) to evaluate whether the study drug (AMTX-100 CF, topical cream, 
1.1%) is safe and efficacious when used to treat Atopic Dermatitis (eczema). Atopic dermatitis 
(eczema) is a condition that makes your skin red, dry and itchy. This study drug is investigational 
because it has not been approved by the U.S. Food and Drug Administration (FDA). The results 
of these studies will be used to design future studies to improve treatment of atopic dermatitis. 
 
The Part 1 (Phase 1) of the study will look at how safe different doses of the investigational drug 
AMTX-100 CF, topical cream, 1.1%, work in improving symptoms of atopic dermatitis. This 
Part 1 (Phase 1) of the study, AMTX100-AD-01, is the first study in which the study drug, 
AMTX-100 CF topical cream, is given to humans. Previous animal studies and pre-clinical work 
have shown that the study drug is both effective in treating eczema like lesions on animals, and 
safe at the dose which you will receive which is much lower than the doses the animals have 
received, however, it is unknown how safe and how well different doses of the investigational 
drug AMTX-100 CF topical cream, 1.1%, will work in human participants with atopic dermatitis 
at this time.  
 
How does AMTX-100 CF  work? 
 
Atopic Dermatitis (AD) is a common, chronic, non-infectious skin condition. The main symptom 
of this inflammatory disease is a very itchy rash. The itch leads to scratching, and more redness, 
swelling, cracking, leaking clear fluid, crusting, and scaling. 
 
In many cases AD gets better as the years go by, and it may go away for a while or disappear 
altogether. AD flare-ups (getting worse at times) however can really affect quality of life. People 
with AD tend to have an over-reactive immune system that when triggered by a substance 
outside or inside the body, responds by producing inflammation. It is this inflammation that 
causes the red, itchy and painful skin symptoms.  
 
AMTX-100 CF study drug product is a white cream with AMTX-100, a new class of medicines 
which target body’s inflammatory responses. AMTX-100, the active ingredient, is a peptide (a 
type of protein), which reduces the inflammatory responses within your skin cells, thus reducing 
eczema symptoms. In Part 1 of the study, AMTX-100 CF topical cream will be applied to the 
eczema affected areas of your skin twice daily for seven (7) consecutive days.  
 
This document uses words such as study treatment, study drug, medication, and participant. Please 
remember this is a research study and the use of these terms does not mean the use of AMTX-100 
CF has been found to be safe or effective for your condition. 
 
Why have I been chosen? 
 
You have been chosen for consideration for this study because you are diagnosed with atopic 
dermatitis (AD), also known as eczema, and your study doctor thinks that you might be a good 
candidate for Part 1 of this study, based on how severe and how large your skin areas are 


Amytrx Therapeutics, Inc./ Protocol Number AMTX100-AD-01  
Page 4 of 21   
  
«PiFullName» 
Advarra IRB Approved Version 27 Feb 2020 
Revised «PIApprovalDate» 
 
affected by AD. In Part 1 (Phase 1) of the study, about 25 participants with atopic dermatitis will 
enroll at about 5 sites within the United States. 
 
Do I have to take part? 
 
You do not have to take part in this study; it is completely voluntary. You will always be free to 
withdraw from the study at any time. If you withdraw during the study, you will be asked to 
come in for a final visit for study evaluations. You do not have to give a reason for your 
withdrawal from the study. This will not affect the standard of care that you will receive, and it 
will not result in any penalty or loss of benefits to which you are entitled. The data collected up 
to that point will be kept with your medical records and will be kept confidential. Your identity 
will not be disclosed. 
 
General Study Design and Duration of Study Involvement 
 
Part 1 of the study is designed to determine how much of the study drug, AMTX-100 CF topical 
cream, 1.1%, is safe to be used on body surface areas affected with AD. 
 
The duration of your participation in Part 1 (Phase 1) of this study will be approximately up to 
six (6) weeks and include four (4) in-clinic study visits to the study center and one (1) 
participation confirmation call by telephone . The study will be conducted in 3 Parts. After the 
initial screening period of the Part 1 study (up to 3 weeks), you will enter study treatment period 
of the Part 1 study (7 days), followed by follow-up period of the study (around 2 weeks). During 
the study treatment period, fourteen (14) doses of AMTX-100 CF topical cream, 1.1%, will be 
applied to all the AD-affected areas as instructed by the study doctor, twice daily for 7 
consecutive days, regardless of whether your AD affected skin areas become better or clear.  
 
There are five (5) different dose levels of AMTX-100 CF topical cream, 1.1%, that will be 
administered in this study. The dose level (group) that you will be assigned to will depend on 
timing, how large your AD affected areas are, and per the study doctor determination:

*Participant will be eligible to unique dose level, depending on how large the skin areas involved 
with atopic dermatitis is. 
 
**Amount of AMTX-100 CF topical cream, 1.1%, will be applied to all treatable AD affected 
areas on your skin, depending on how large your skin areas involved with atopic dermatitis is. 
 
 
 
 
 
 
 
 
 
  
 
 
 
 
 
 
 
 
NOTE:  
The study doctor will conduct dermatologic evaluations on you to evaluate your symptoms of 
atopic dermatitis on each clinical visit. These evaluations will include questionnaires, assessment 
scales and pictures of AD affected skin areas to confirm the atopic dermatitis diagnosis and, 
determine how severe symptoms of atopic dermatitis are.  
 
The questionnaires, assessment scales and pictures will not include any identifying information 
about you (name, address, phone number, physical appearance, etc.), but will be labeled with a 
unique subject ID number assigned to you to protect confidentiality and some of them may be 
uploaded to a secure internet portal. The applicable study team members will need specific login 
credentials to be able to access the questionnaires, assessment scales and pictures on this secure 
internet portal. No one other than the study team will have access to this portal. The 
questionnaires, assessment scales and pictures may be used by the study Sponsor (Amytrx 
Therapeutics, Inc) or people or companies working with the Sponsor for research purposes only 
as described above and will not be sold to other people or companies for commercial purposes. 
De-identified pictures may or may not be used in future publication. The questionnaires, 
assessment scales and pictures uploaded to the secure internet portal will be destroyed 
immediately after study analyses completion.

Page 10 of 21   
  
«PiFullName» 
Advarra IRB Approved Version 27 Feb 2020 
Revised «PIApprovalDate» 
 
Follow-Up Visit (Visit 5: Day 21±2) 
During the follow-up visit, the following assessments will be performed: 
 
 
 
 
 
 
  
 
 
 
 
 
  
 
 
 
 
 
 
 
 
 
  
 
 
 
  
 
This visit will take about 1-2 hours of your time. 
 
Withdrawal Visit: 
For participants who withdraw/are discontinued prematurely during study treatment period, 
“Withdrawal visit” assessments will be performed. Visit 4 assessments will be performed as the 
withdrawal visit evaluations. For all withdrawn/discontinued subjects during study treatment 
period, the Follow-up visit (Visit 5) will happen 2 weeks after the withdrawal visit evaluations.  
 
What are the risks of taking part? 
 
This Part 1 (Phase 1) of the study, AMTX100-AD-01, is the first study in which the study drug, 
AMTX-100 CF topical cream, is given to humans. 
 
There are risks to taking part in any research study. AMTX-100 (active ingredient) and AMTX-
100 CF topical cream (drug product) are still undergoing testing and there may be side effects 
that are unknown at this time.  
 
 


Amytrx Therapeutics, Inc./ Protocol Number AMTX100-AD-01  
Page 11 of 21   
  
 
 
 
 
 
 
 
 
 
 
 
Animal studies have not indicated that AMTX-100 or AMTX-100 CF topical administration 
might be associated with allergic reactions. 
 
Since AMTX-100 (active ingredient) and AMTX-100 CF topical cream (study drug product) 
have not been studied in humans and AMTX-100, active ingredient, is a new class of medicines 
for atopic dermatitis, side effects in humans are not known. You may or may not experience side 
effects of skin irritation observed in the animal study, however, this is unlikely because the skin 
irritation in animal studies was determined to be due to not appropriately washing off the study 
cream administration sites between AMTX-100 CF twice daily applications for 14 days. To 
reduce the risk of skin irritation, bathing the treated areas will be allowed once daily and 
should be done at least every 3 days keeping normal daily hygiene. 
 
You will be monitored carefully during the administration of study drugs and will be watched 
carefully for side effects or any allergic reactions. As with any study drug, there is a risk of 
allergic reaction.  If you have a very serious allergic reaction, you may be at risk of death.  Some 
symptoms of allergic reactions are: 
 
• 
Rash 
• 
Wheezing and difficulty breathing 
• 
Dizziness and fainting 
• 
Swelling around the mouth, throat or eyes 
• 
A fast pulse 
• 
Sweating 
You need to tell your study doctor or study staffs immediately if you experience any side 
effects, any unfavorable signs or symptoms. If any safety concerns arise, the study treatment 
may be stopped.  
 
Some redness, faintness, pain and swelling may happen due to the blood draws. You may 
experience bruising or bleeding at the site where the needle was placed. There is also a slight 
possibility of infection. 
 
If you do not understand what any of these side effects mean, please ask the study doctor or the 
study staff to explain them to you. 
 
It is unknown whether or not AMTX-100 and AMTX-100 CF topical cream will have any effect 
on unborn children or babies. It is unknown if AMTX-100 can pass through breast milk and it is

that such injury results from the study treatment or any other procedure carried out in accordance 
with the plan for the study. The sponsor has no plans to compensate you where such injury 
results from any procedure carried out which is not in accordance with the plan for the study. 
Your legal right to claim compensation for injury is not affected or waived in any way.  
 
If you are injured as a direct result of the use of the study drug, Amytrx Therapeutics, Inc will 
pay for medical expenses for the treatment of the injury that are not covered by your medical 
insurance, a government program or any other third party. Medical care will be provided to you 
through the study doctor and/or institution to treat any physical injury incurred as a direct result 
of the use of the study drug. You must agree to cooperate in obtaining any proceeds from 
insurance or other third party coverage that may be available to you with respect to the costs of 
such medical care. No financial or other form of compensation (such as lost wages or 
discomfort) will routinely be available to you for such injuries; however, you will not lose any of 
your legal rights or release the Sponsor, the study doctor, the study staff, or study site from 
liability for mistakes or intentional misconduct by signing and dating this consent document. 
 
You should talk to the study doctor if you have any questions regarding the study treatment 
during the study, if you feel you did not receive the study treatment you expected, or any other 
concerns. The name and phone number of your study doctor is printed on the first page of this 
consent form. 
 
If you experience a side effect or injury that may be related to this study or if you have an 
unscheduled visit for medical care for any reason, please contact the study doctor listed on page 
one of this informed consent. 
 
If you claim to have become sick or injured from participating in this study, Amytrx 
Therapeutics, Inc. may give information that identifies you to its insurance carrier.  This 
information will be used by the insurance carrier solely for the purpose of resolving your claim. 
To pay medical expenses, the sponsor will need to know some information about you like your 
name, date of birth, and Medicare Beneficiary Identifier (MBI). This is because the sponsor has 
to check to see if you receive Medicare and if you do, report the payment it makes to Medicare. 
 
Will my taking part in this study be kept confidential? 
 
If you agree to take part in this study, your identity and medical records will be kept confidential 
and will not be disclosed outside of the hospital/study site/family physician’s office unless 
required by law. Your medical records may be inspected by Amytrx Therapeutics, Inc (the 
company sponsoring the study).  Your records may also be inspected by a company Amytrx 
Therapeutics, Inc has delegated some study management to, Amarex Clinical Research, LLC. 
(Amarex), for purposes of analyzing the study results and monitoring the study. Regulatory 
authorities such as the U.S. Food and Drug Administration (FDA) and Institutional Review 
Boards (IRB) may review study results and participants records to check that the study is being 
conducted correctly. This means that absolute confidentiality cannot be guaranteed.  If the results 
of this study are published or presented at meetings, you will not be identified.

What if new information becomes available? 
 
During the course of a research study, new information may become available about your disease 
or the study treatment that is being studied that might change your decision to be in this study. If 
this happens, your study doctor will discuss this with you and whether you want to continue in 
the study. If you decide to withdraw, your study doctor will make arrangements for your 
prescribed standard conventional therapy to continue. If you decide to continue in the study you 
will be asked to sign and date an updated consent form. 
 
Also, on receiving new information your study doctor might consider it to be in your best interest 
to withdraw from the study. The study doctor will explain the reasons and arrange for your 
prescribed standard care to continue. 
 
What will happen to the results of the research study? 
 
Once the study has finished, the information will be analyzed and a clinical study report will be 
written to record the results. This process can take about 6 months. Your study doctor will be 
kept informed of the results from the study, and a paper detailing these results will probably be 
published in an appropriate medical journal. You can also ask the study doctor for the results of 
the study. 
 
Who is organizing and funding the research? 
 
The company sponsoring and funding this research study is Amytrx Therapeutics, Inc. The study 
site and/or your study doctor is receiving financial support from the sponsor for undertaking this 
study. 
 
Voluntary participation / Withdrawal 
 
Your participation in this study is voluntary. You may decide not to participate or may leave the 
study at any time. Your decision will not result in any penalty or loss of benefits to which you 
are entitled. Tell the study doctor if you are thinking about stopping or have decided to stop.  The 
study doctor will tell you how to stop your participation safely.  
 
It is important to tell the study doctor if you are thinking about stopping your participation so 
that your doctor can evaluate any risks from the study drug and discuss what alternative follow-
up care and testing could be most helpful for you. If you withdraw during the study, you will be 
asked to come in for withdrawal visit, followed by safety follow up visit for safety reasons. Even 
if you don’t want to return for follow-up visits and blood tests, we would still like to collect 
information by phone or available medical records about your disease status. 
 
Early Termination: 
Your participation in this study may be stopped at any time by the study doctor, the sponsor 
(Amytrx Therapeutics, Inc.), the FDA, and/or the IRB without your consent for any of the 
following reasons:

Authorization to Use and Disclose Protected Health Information (HIPAA 
Authorization) 
 
While you are participating in this research study, the study doctor and his/her 
study staff will collect and create personal health information about you and record 
it on study forms. This information may include health histories, examinations, and 
results of tests. The study doctor will keep this information in study records. 
He/she may also gather information regarding your past, present, and/or future 
medical conditions from your primary medical doctor. These records may also 
include personal information such as your birth date, social security number, or 
medical record numbers which could be used to identify you. This type of 
information is called “Protected Health Information” (PHI). 
 
Under a United States federal law called the “Privacy Rule” or Health Insurance 
Portability and Accountability Act of 1996 (HIPAA), no one’s PHI that is gathered 
and obtained during research can be used to conduct the research or be given to 
anyone for research purposes without one’s permission. Because of this rule, you 
may not participate in this study unless you give your permission to use and 
disclose your PHI. 
 
By signing and dating this authorization, you are giving permission for the study 
doctor and his/her study staff, along with the Sponsor (Amytrx Therapeutics), 
Amarex Clinical Research (the Contract Research Organization) and the 
Regulatory authorities such as the U.S. Food and Drug Administration (FDA) and 
Institutional Review Boards (IRB) to use your PHI to conduct this study, to 
monitor your health status, and possibly to develop new tests, procedures, and 
commercial products.  
 
You are also agreeing to allow your PHI to be disclosed to the study sponsor and 
any representatives working with them. The sponsor may also give your PHI to the 
FDA or other regulatory agencies. Study staff will assign a code number to you for 
this study. This will help to protect your identity; however, the sponsor may look at 
your complete study records which will identify you. The sponsor will also send 
representatives to your study doctor’s office to oversee how the study is being 
conducted. These representatives will review your PHI to make sure the 
information is correct. The IRB may also have access to your PHI to meet its 
oversight responsibilities. These disclosures help to make sure that all information 
related to the research is available to those who need it.

Your identity will remain confidential, except for the disclosures described above 
and detailed specifically in the consent page, and will not be shared with others, 
unless it is required by law. If your PHI is given to the parties listed above or to 
anyone who is not required to follow federal law, your PHI will no longer be 
protected by the “Privacy Rule” and could possibly be used or disclosed in ways 
other than those listed here. 
 
You have the right to see and make copies of your PHI. You are agreeing, 
however, not to see or make copies of your PHI until all of the sponsor work has 
been completed. At that time, you may ask to see your records. 
 
Your HIPAA Authorization will expire 50 years from the date you sign it unless 
you revoke (cancel or withdraw) it sooner. You have the right to cancel or 
withdraw this authorization at any time. If you cancel this authorization, your PHI 
will no longer be used for this study, unless it is necessary (based on your earlier 
authorization) to complete analysis (tests) and reports for this research. 
 
To cancel your permission to use PHI, you must send a written notice to your study 
doctor’s office at the address listed on page one stating that you are canceling your 
authorization for them to use or disclose your protected health information. If you 
cancel this authorization, you will not be allowed to continue in this study. 
 
Subjects will receive a signed and date copy of this document.

INTRODUCTION 
1.1 
STATEMENT OF INTENT 
The design, conduct and reporting of this trial shall be conducted in compliance with the protocol, 
International Conference on Harmonization (ICH)/Good Clinical Practice (GCP) and all appropriate 
regulatory requirements. The protocol will follow 21 Code of Federal Regulations (CFR) 50, subpart D 
and will provide all the necessary safeguards for study subjects. All of the Investigators will have 
documented training in GCP. Independent monitoring of the trial will be accomplished by utilizing a 
Contract Research Organization (CRO). 
1.2 
STUDY BACKGROUND  
Atopic Dermatitis (AD) is a chronic, pruritic inflammatory skin disease of unknown origin that usually 
starts in early infancy, but also affects a substantial number of adults. AD affects 15-30% of children and 
2-10% of adults globally, and its prevalence rate is rising (Alhazmi, 2017). AD onset is most common 
between 3 and 6 months of age, with approximately 60% of patients developing the eruption in the first 
year of life and 90% by 5 years of age (Kay, 1994; Perkin, 2004).  While the majority of affected 
individuals have resolution of disease by adulthood, 10% to 30% do not, and a smaller percentage of 
individuals first develop symptoms as adults (Ellis, 2012).  
AD is often associated with elevated serum immunoglobulin (IgE) levels and a personal or family history 
of type I allergies, allergic rhinitis, and asthma (Eichenfield, 2014). AD typically presents with pruritus, 
xerosis, lichenification, and eczematous lesions. Excoriations and crusting are common and some 
patients exhibit prurigo nodularis‒like lesions. The eczematous changes and its morphology are seen in 
different locations depending on the age of the patient. In adults, lesions are more diffuse with an 
underlying background of erythema. The face is commonly involved and is dry and scaly. The mainstays 
of treatment are moisturization (frequent lukewarm baths, and using petrolatum or Aquaphor, etc.), along 
with topical steroids (Eichenfield, 2014). For more severe cases, other treatment options such as 
immunomodulators (ex. tacrolimus and pimecrolimus), biologicals (ex. dupilumab and omalizumab), 
topical phosphodiesterase-4 (PDE-4) inhibitors (ex. crisaborole), probiotics and phototherapy are also 
used (Sidbury, 2014). All of these options for AD management, and many of these treatment regimens 
are considered expensive and with various side effects in chronic use. Thus, patients with AD are in need 
of new treatment options that are efficacious and safe in the long term use.  
AMTX-100 CF3 drug product is formulated as a water-based, topical cream incorporating a 28-amino 
acid synthetic polypeptide (AMTX-100) as the active pharmaceutical ingredient (API).  
AMTX-100 is a chimeric, cell-penetrating, bifunctional nuclear transport modifier (NTM), that is 
engineered to modulate nuclear transport of transcription factors (NF-κB, NFAT, AP-1 and STAT1) 
involved in activation of gene expression of key mediators of inflammation (TNFα, IL-1β, IL-6, IL-17, 
MCP-1, etc.) and metabolic syndrome (ChREBP and SREBP) by importin α/β complex and importin β,

respectively. This further leads to a reduction in pro-inflammatory cytokine/chemokine production and 
carbohydrate and lipid metabolic products.  
Several nonclinical safety studies have been conducted with AMTX-100 and AMTX-100 CF to evaluate 
its toxicological profile and additional studies are currently ongoing. Substantial scientific literature is 
also available on the anti-inflammatory mechanisms of AMTX-100.  
The current study is designed to evaluate the safety and tolerability of open-label topically applied 
AMTX-100 CF3 (in 1.1% concentration) and to evaluate the safety and efficacy of topically applied 
AMTX-100 CF3 (1.1% w/w) in adult patients with mild to moderate AD.

STUDY DESIGN RATIONALE 
Following substantial prior pre-clinical studies, to further evaluate the safety and efficacy of different 
doses of AMTX-100 drug product in improving symptoms associated with mild to moderate atopic 
dermatitis, Amytrx Therapeutics, Inc (Sponsor) plans to conduct this Two-part, Phase I/II, Multi-center, 
Double-Blind, Randomized, Vehicle-controlled Study of the Safety and Efficacy of topically applied 
AMTX-100 CF in adult patients with Mild to Moderate Atopic Dermatitis. 
1.5 
RISKS AND BENEFITS, AND PRECAUTIONS TO MINIMIZE RISK  
To ensure that AMTX-100 (active pharmaceutical ingredient) and AMTX-100 CF (topical 
formulation) are safe as a human therapeutic agent, below safety studies were conducted. All 
toxicology studies of AMTX-100 CF and AMTX-100 are listed in Table 1-1, including information 
on the Good Lab Practices (GLP) status and testing facility.

All these study results indicate that AMTX-100 CF topical formulation is safe for clinical application. 
Based on the current data, AMTX-100 may show anti-inflammatory mechanism of action and improve 
symptoms associated with atopic dermatitis. 
1.5.1 ALLERGIC REACTION 
Pre-clinical studies have not shown that AMTX-100 or AMTX-100 CF topical administration might be 
associated with allergic reactions, however in this first in human study sufficient surveillance of any 
adverse events and administration reactions will be conducted.  
1.5.2 PREGNANCY 
Risks to unborn babies are unknown at this time, thus pregnant females will be excluded from this study. 
Females of childbearing potential must have a negative pregnancy test prior to enrollment and must agree 
to use appropriate birth control methods throughout the study duration (excluding women who are not 
of childbearing potential).  
1.5.3 VENIPUNCTURE FOR BLOOD SAMPLING 
Venipuncture for blood sample collection carries a minimal risk of minor discomfort and the possibility 
of minor bruising at the site of the needle puncture and, rarely, the possibility of infection at the needle 
puncture site. 
1.5.4 UNKNOWN RISKS 
As with all research there is the remote possibility of risks that are unknown or that cannot be foreseen 
based on current information.

STUDY DESIGN  
This is an adaptive, Phase I/II study in 2 parts: Part 1 (Maximum Tolerable Dose (MTD) Finding by 
maximum BSA percentage treated) and Part 2 (evaluating efficacy of AMTX-100 CF3 1.1% w/w 
concentration versus placebo (vehicle)). 
3.1 
PHASE I (PART 1) STUDY DESIGN 
Part 1 of this study is an open-label, dose escalation study of the safety and tolerability of topically 
applied AMTX-100 CF in adult patients with mild to moderate AD. Part I of this study is designed to 
determine the MTD of AMTX-100 CF (1.1% w/w concentration) for the highest treated percentage of 
the BSA affected with AD. The MTD is defined as 1 cohort dose level below the dose, in which dose 
limiting toxicities (DLTs) as defined below were observed. 
In total, five (5) cohort dose levels will be tested sequentially by escalating AMTX-100 CF 1.1% to 
higher percentage of BSA affected with AD at each cohort. Each enrolled subject will receive the 
assigned dose of Open-label AMTX-100 CF 1.1% w/w to be applied twice daily to all treatable lesions 
of AD (excluding the scalp, face, eyes, eyelids, neck, hands, palms, feet, groin, genitals or in the axillae) 
for 7 consecutive days (14 applications in total), regardless of whether the lesions become clinically clear 
during the 7 days treatment period.

PHASE II (PART 2) STUDY DESIGN 
Phase II (Part 2) of this study is a multi-center, double-blind, randomized, vehicle-controlled study of 
the safety and efficacy of topically applied AMTX-100 CF3 in adult patients with Mild to Moderate AD. 
Sixty (60) subjects will be enrolled in 2 groups of AMTX-100 CF3 and placebo (vehicle). The subjects 
will be randomized in a 1:1 ratio, thus thirty (30) subjects will be randomized in each group (Group A: 
Treatment 1.1% w/w of AMTX-100 CF3) and Group B: placebo (vehicle 0% w/w)). Each enrolled 
subject, after screening and randomization, will receiveAMTX-100 CF3 1.1% w/w or placebo (vehicle) 
to be applied twice daily to all treatable AD lesions (excluding the scalp, face, eyes, eyelids, hands, 
palms, feet, groin, genitals or in the axillae) for 28 consecutive days.  
The study groups are as follows: 
• Group A: AMTX-100 CF3 dose concentration (1.1% w/w), topically applied twice a day for 28 
consecutive days to all treatable AD affected areas  
• Group B: Placebo (Vehicle) (0% w/w), topically applied twice a day for 28 consecutive days to all 
treatable AD affected areas

Important Notes: 
1. Subjects may drop out or be withdrawn at their own request. Although subjects do not need to give 
a reason for requesting withdrawal from the trial, the Investigator should make a reasonable effort to 
ascertain the reason(s), while fully respecting the subject's rights. 
2. Any subjects reporting Serious Adverse Events (SAEs) that have not been resolved by their last study 
visit will be followed to resolution or until 30 days after the subject completes the study. 
3. Every attempt should be made to collect follow-up information. The reason for withdrawal from the 
study (if known) will be recorded in the source documents and on the appropriate page of the eCRF. 
4. Before a subject is identified as lost-to-follow-up, the site should make all reasonable efforts to 
contact the subject. These attempts must be documented and should include at a minimum one phone 
call and one follow-up letter.  
5.3 
SCREEN FAILURES 
A subject who has signed the consent form but is not randomized is classified as a screen failure. The 
screen failure must be entered into the study eCRFs. Subject number, demographic information, and 
reason for screen failure will be collected. If a subject initially fails to meet inclusion/exclusion criteria 
and is later reconsidered for participation, the subject can be re-consented only once more, at least 30 
days after the initial screening. The subject will need to be re-consented in such a case and will be 
assigned a new screening number at the time of re-screening.

HEIGHT, WEIGHT, BMI AND BSA 
Measurements will be taken in street clothing with jacket/coat and shoes removed. Body Mass Index 
(BMI) will be calculated from the height and weight measurements using the following formulas: 
 
• Metric: BMI = Weight (kg) / [Height (m)]2 
Or, 
• Imperial: BMI= Weight (lb) / [Height (in)]2 x 703 
 
Total Body Surface Area (BSA) will be calculated from the height and weight measurements using the

PHYSICAL EXAM 
The physical examination will include routine examinations, including dermatologic examination, but 
not including rectal or genitourinary examinations. All clinically significant abnormalities will be 
recorded in subject’s medical record and on the physical exam CRF page. Any abnormality that, in the 
opinion of the Investigator, is relevant to the safety of the subject or could impact safety or efficacy 
results for the subject will be considered as “clinically significant”. After administration of the first dose 
of study treatment, each physical exam abnormality that is clinically significant will be recorded as an 
AE.

URINE PREGNANCY TEST 
Urine pregnancy test will be performed for females of child-bearing potential. The result must be 
documented on the source documents and in the eCRF. Subjects who are found to be pregnant during 
the screening period will be considered a screen failure. If pregnancy occurs during the course of the 
study, the subject will be withdrawn from the study and the pregnancy will be followed up to term for 
safety purposes. Relevant safety information collected after the study has completed will be reported as 
supplemental information. 
8.10 ELECTROCARDIOGRAM (ECG) 
A standard 12-lead ECG will be performed per the site standard procedures. The following parameters 
will be recorded (as part of the subject’s medical record) and recorded on the appropriate page of the 
CRF: ventricular rate (beats per minute), PR interval (msec), QRS interval (msec), QT interval (msec), 
and QTc interval (msec). Additionally, the Investigator will record the overall results of the ECG reading 
as either normal or abnormal, and if abnormal, as either “not clinically significant” or “clinically 
significant.” If abnormalities are observed, each will be recorded. Each treatment-emergent abnormality 
that is clinically significant will be recorded as an AE. Each ECG should be signed by a physician. 
8.11 COHORT ASSIGNMENT (PART 1 ONLY, SEQUENTIAL) 
In Phase I (Part 1) of the study, five (5) cohort dose levels will be tested sequentially by escalating 
AMTX-100 CF 1.1% application of treatable % BSA involvement at each cohort. Five (5) cohorts will 
be sequentially enrolled in the Part 1 of the study.  
Site personnel will be notified about the cohort (dose level) escalation to the higher dose level cohort. 
Subjects will be assigned in the designated cohort (dose level) at the time of screening, using an 
Interactive Web Response System (IWRS) and site personnel will be trained on this system.

SAMPLE SIZE DETERMINATION AND RATIONALE 
Sample size for Phase I (Part 1): The sample size of 25 subjects (5 subjects per cohort) for Phase I of 
this study is selected on the basis of clinical judgment and not based on statistical power calculation. The 
number of subjects is deemed adequate to provide clinically meaningful descriptive results consistent 
with study objectives.  
Sample size for Phase II (Part 2): The sample size of 60 subjects for Phase II of this study is selected 
on the basis of clinical judgment and not based on statistical power calculation. The number of subjects 
is deemed adequate to provide clinically meaningful results consistent with study objectives. 
9.4 
RANDOMIZATION 
There is no randomization for the Phase I (Part 1) of the study. In Phase II (Part 2) of the study, subjects 
will be randomized using a web-based randomization system at Visit 2 and site personnel will be trained 
on this system. Only those subjects who successfully complete the screening phase and meet the study 
eligibility criteria will proceed to randomization. The randomized subjects will receive study treatment 
at the assigned doses for 28 consecutive days (56 applications in total) and followed up for 2 weeks to 
assess post-treatment safety. 
9.5 
BLINDING AND PREVENTION OF BIAS 
There is no blinding for the Part 1 of the study. However, all subjects, Investigators and their staff, and 
all Sponsor/CRO personnel involved in the management of the study will be blinded to treatment 
assignments for the Part 2 of the study. Treatment unblinding for the study will occur after all clinical 
data have been received, data inconsistencies have been resolved, and the database is locked, except for 
the interim analysis or for safety reasons on a case-by-case basis (i.e., emergency unblinding).

10 ADVERSE EVENTS (DEFINITIONS AND REPORTING) 
The Investigator is responsible for the detection and documentation of events meeting the criteria and 
definition of an AE or SAE, as provided in this protocol. During the study when there is a safety 
evaluation, the Investigator or site staff will be responsible for detecting, documenting, and reporting 
AEs and SAEs as detailed in this section of the protocol.  
10.1 ADVERSE EVENTS 
An adverse event (AE) is defined as any unfavorable or unintended sign, symptom, or disease that occurs 
or is reported by the subject to have occurred, or a worsening of a pre-existing condition. An AE may or 
may not be related to the study treatment.  
AEs will be elicited through direct questioning and subject reports. Any abnormalities in visit 
evaluations, physical examination findings or laboratory results that the Investigator believes are 
clinically significant to the research subject and that occurred after initiation of the first study treatment 
will be reported as AEs. Abnormal findings that are NOT clinically significant should not be recorded 
as an AE. 
10.1.1 REPORTING OF ADVERSE EVENTS 
Report initiation for all AEs and SAEs will begin at the time of the first study treatment administration 
and continue up until the final study visit. All events will be followed to resolution or until they are 
considered as non-clinically significant event. 
All AEs must be recorded in the subject’s medical records and on the CRF. AEs will be reported using 
customary medical terminology along with the following information: the onset and end dates, whether 
the event is considered to be an SAE (see Section 10.2), the impact the event had on study treatment (see 
Section 10.1.2), the CTCAE grade (intensity) of the event (see Section 10.1.3), the causality of the event 
(see Section 10.1.4), whether treatment was given as a result of the event (see Section 10.1.5), and the 
outcome of the event (see Section 10.1.6). 
10.1.2 IMPACT ON STUDY TREATMENT 
The impact the event had on the study treatment will be assessed as either: none, study treatment 
interrupted, study treatment discontinued, or not applicable. The “not applicable” assessment will be 
used only when the subject is no longer in the treatment phase of the protocol, or if the outcome of the 
event was “death”. 
10.1.3  SEVERITY (INTENSITY) ASSESSMENT 
The guidelines outlined in CTCAE v5.0 will be used for assessing the severity or intensity of the event. 
The general guidelines for assessing the AE grade appear below. Full guidelines may be obtained at 
http://evs.nci.nih.gov/ftp1/CTCAE.

4. Unlikely related: In general this category can be considered applicable to those AEs which, after 
careful medical consideration at the time they are evaluated, are judged likely to be unrelated to 
the study treatment. An AE may be considered unlikely if or when (must have two): (1) it does 
not follow a reasonable temporal sequence from administration of the study treatment. (2) It 
could not readily have been produced by subject’s clinical state, environmental or toxic factors, 
or other therapies administered to the subject. (3) Disappears or is decreased upon discontinuation 
of the study treatment. (4) It does not follow a known response pattern to treatment with the study 
treatment.  
5. Unrelated: This category applies to those AEs which, after careful consideration at the time they 
are evaluated, are clearly and incontrovertibly due to extraneous causes (disease, environment, 
etc.) and determined with certainty to have no relationship to the study treatment.  
10.1.5 TREATMENT GIVEN AS A RESULT OF THE EVENT 
The event impact in terms of treatment provided will be as either: none, medication administered, non-
medication therapy administered, surgery, or other (with a specification). 
10.1.6 OUTCOME ASSESSMENT 
The outcome of the event will be assessed as either: resolved, resolved with sequelae, ongoing, or death. 
Only one AE per subject is allowed to have an outcome assessment as “death.” If there are multiple 
causes of death for a given subject, only the primary cause of death will have an outcome of death.   
10.1.7 EXPECTED /ANTICIPATED ADVERSE EVENTS 
 
 
 
 
 
 
10.1.8 APPLICATION SITE REACTIONS 
For this population, presence of signs/symptoms similar to application site reactions at the eczema 
lesions at the baseline is expected. Only significant worsening of these signs/symptoms from the baseline 
per the investigator would be considered adverse events.

10.4   SAE FOLLOW-UP 
All subjects experiencing an SAE, including the discontinued subjects, must be closely followed until 
sufficient information is obtained to indicate a return to normal status or until the event stabilizes at a 
level acceptable to the investigator (i.e., recovery, return to baseline status, no further improvement 
expected, or death). 
For each SAE indicated as an unresolved event on the initial report, regardless of whether the subject 
completed the study or withdrew, the site should submit a follow-up report with updated information.

13 QUALITY CONTROL AND QUALITY ASSURANCE 
13.1 MONITORING REQUIREMENTS 
In an effort to fulfill the obligations outlined in 21 CFR Part 312 and ICH guidelines which require the 
Sponsor to maintain current personal knowledge of the progress of a study, the Sponsor's designated 
monitor will visit the center(s) during the study as well as maintain frequent telephone and written 
communication. The Investigator will permit the Sponsor to monitor the study as frequently as is deemed 
necessary and provide access to medical records to ensure that data are being recorded adequately, that 
data are verifiable and that protocol adherence is satisfactory.  
The Investigator will permit representatives of the Sponsor and/or designated CRO to inspect all CRFs 
and corresponding study subject original medical records (source documents) at regular intervals 
throughout the study. Subject original medical records and other relevant data must be available to 
support all data recorded in the CRF. In addition to the original medical records, these data may include 
but are not limited to, study, laboratory and diagnostic reports, wound images and tracings, etc.  
Site inspections serve to verify strict adherence to the protocol and the accuracy of the data being entered 
on the CRFs, in accordance with federal regulations. A Monitoring Log will be maintained at each study 
site that the monitor will sign, date, and state the type of visit.  
The Investigator should be aware that the study site and subject records may be inspected by the Sponsor 
and or representatives of the designated CRO, FDA, or other regional regulatory authority. 
The final statistical analysis of data will be performed after all clinical monitoring has been completed, 
all data queries have been resolved, and all data have been verified (Quality Control checked) prior to 
formal database lock. The Sponsor will authorize the final database lock. 
13.2 ACCEPTABILITY OF CASE REPORT FORMS  
All CRFs will be completed as soon as possible after the subject's visit. Corrections to data on the CRFs 
will be made according to standard data correction procedures. The Investigator will review CRFs to 
indicate that, to his/her knowledge, they are complete and accurate. CRFs will be reviewed by the 
Sponsor’s or designated CRO’s monitor, who will make a decision as to their acceptability.   
13.3 MODIFICATION OF PROTOCOL 
The Investigator will not modify or alter this protocol without first obtaining the concurrence of the 
Sponsor. Approval by the Investigator’s IRB must also be obtained prior to implementation of the 
change, with two exceptions: 
 
1. When necessary to eliminate apparent immediate hazard to the subject; or 
2. When the modification does not involve the subject’s participation in the trial.

An amendment may also require modification of the ICF. The Investigator will provide an approval 
letter for the amendment and revised ICF, if applicable, to the Sponsor. An amendment must be in writing 
and it must be dated by both the Sponsor and the Investigator. If necessary, the Sponsor will submit 
protocol amendments to FDA and other appropriate regulatory authorities and notify other Investigators 
using this protocol. 
13.4 REPORTING PROTOCOL DEVIATIONS 
The Investigator is obligated to follow the protocol without departure from the requirements written in 
the protocol. If the Investigator deviates from the protocol requirements, the Sponsor will make the 
determination as to whether the subject will continue in the study. The Sponsor also has the right to 
discontinue the subject for protocol violations. The IRB may also have to be contacted if safety to the 
subject or if the scientific soundness of the study is involved. All protocol deviations must be 
documented in the CRFs.

they are free to refuse entry into the study and free to withdraw from the study at any time without 
prejudice to future treatment. The written ICF is to be in compliance with CFR 21 Part 50.27, 45 Part 46 
and GCP guidelines. The Sponsor and/or designated CRO will approve the ICF and all amendments to 
the ICF prior to submission to the IRB/IEC. A copy of the ICF to be used will be submitted by the 
Investigator to the IRB/IEC for review and approval prior to the start of the study. Each study site must 
provide the Sponsor with an unsigned copy of IRB/IEC-approved ICF along with applicable 
documentation to support this approval. The original signed ICF is retained in the subject's study records, 
and a copy is provided to the subject. A second copy may be filed in the subject’s medical record, if 
allowed by institutional policy.

15 DATA HANDLING AND RECORD KEEPING 
15.1 RECORDING AND COLLECTION OF DATA 
The primary source document for this study will be the subject's medical records. If separate research 
records are maintained by the Investigator(s), the medical records and the research records will be 
considered the source documents for the purposes of auditing the study.  
Applicable source data will be manually transcribed to the approved CRFs. The Investigator is ultimately 
responsible for the accuracy of the data transcribed on the forms. All source documents and CRFs will 
be completed as soon as possible after the subject's visit. 
The Investigator will review CRFs to indicate that, to his/her knowledge, they are complete and accurate. 
If further changes are made after this, the Investigator will need to again sign the Investigator signature 
page. Designated source documents will be signed and dated by the appropriate study personnel. The 
Investigator must agree to complete and maintain source documents and CRFs for each subject 
participating in the study. The Investigator will maintain a confidential list of study subjects that will 
include each subject’s study number, name, date of birth and unique hospital identification number if 
applicable. This list will be kept by the Investigator and will not be collected by the Sponsor. A notation 
will be made in the subject’s case history/medical chart that he/she is participating in a clinical study and 
that the subject has provided a signed and dated ICF accordingly as well as the required site HIPAA 
authorization (if separate from the ICF). The Investigator must also maintain a separate screening log of 
all the subjects screened for participation in the study; it should include gender; age; eligibility status; 
reason for ineligibility, if applicable; and study allocated subject number, if applicable.  
15.2 CLINICAL DATA MANAGEMENT 
The Sponsor and/or designated CRO will be responsible for the processing and quality control of the 
data. Data management will be carried out as described in the Sponsor’s or CRO’s standard operating 
procedures (SOPs) for clinical studies. 
The handling of data, including data quality control, will comply with regulatory guidelines (e.g., ICH 
E6 GCP, and local regulations where applicable) and the Sponsor’s or the CRO’s SOPs as well as 
provisions of the study-specific Data Management Plan. All research data will be entered, either 
electronically or manually, into a computerized database, designed in accordance with 21 CFR Part 11 
and based on protocol requirements defined by the Sponsor in association with clinical data manager, 
including double-data entry. The data will be reviewed, manually and/or electronically, and queries will 
be prepared for any data discrepancies. 
15.3 ARCHIVING 
All study documentation at the Investigator site and Sponsor site will be archived in accordance with 
ICH GCP E6 and the Sponsor’s quality standards and SOPs.

(21CFR 50.25(c)). 
 
Introduction 
 
You are being invited to take part in this clinical research study because you have been 
diagnosed with atopic dermatitis (also known as eczema), a skin condition that makes your skin 
red, dry and itchy.  
 
The name of the study drug involved in this study is: 
• AMTX-100 CF3, topical cream, 1.1%  
 
For purposes of this research, you will be referred to as a “participant”.   
 
Amytrx Therapeutics, Inc. (Amytrx), a pharmaceutical company based in U.S., is supporting this 
research study by providing study drug and funding for this research study. 
 
Before you decide to take part in this study, it is important for you to understand why the 
research is being done and what it will involve. This consent form may contain words that you 
do not understand. Please take the time to read the following information carefully and feel free 
to take home an unsigned copy of this consent form to discuss this information with your family, 
friends, relatives and/or your study doctor or other primary care physicians (PCP). Please ask the 
study doctor or one of the study staff to explain any words or information that you do not clearly 
understand. Feel free to request more information about the study.

concentration) topical cream is safe and efficacious when used to treat Atopic Dermatitis 
(eczema). Atopic dermatitis (eczema) is a condition that makes your skin red, dry and itchy. This 
study drug is investigational because it has not been approved by the U.S. Food and Drug 
Administration (FDA). The results of these studies will be used to design future studies to 
improve treatment of atopic dermatitis. 
 
Previous animal and pre-clinical studies have suggested that the study drug is both effective in 
treating eczema-like lesions on animals, and safe at the doses proposed for human use. As for 
previous human clinical trials, Part 1 (Phase I) of this study has been completed already, in 
which 26 participants with atopic dermatitis were enrolled and applied the study drug twice daily 
for 1 week. The study results showed the study drug was both safe and efficacious in treating 
atopic dermatitis lesions.  
 
Part 2 (Phase II) of the study (current study you are considering) will further explore the safety 
and efficacy of the investigational drug (AMTX-100 CF3 topical cream, which includes 1.1% of 
the active ingredient AMTX-100), in improving symptoms of atopic dermatitis compared to 
placebo (topical cream with 0% of the active ingredient AMTX-100).  
 
How does AMTX-100 CF3 work? 
 
Atopic dermatitis (AD) is a common, chronic, non-infectious skin condition. The main symptom 
of this inflammatory disease is a very itchy rash. The itch leads to scratching, and more redness, 
swelling, cracking, leaking clear fluid, crusting, and scaling. 
 
In many cases AD gets better as the years go by, and it may go away for a while or disappear 
altogether. AD flare-ups (getting worse at times) however can really affect quality of life. People 
with AD tend to have an over-reactive immune system that when triggered by a substance 
outside or inside the body, responds by producing inflammation. It is this inflammation that 
causes the red, itchy and painful skin symptoms.  
 
AMTX-100 CF3 study drug product is a white cream with AMTX-100, a new class of medicines 
which target body’s inflammatory responses. AMTX-100, the active ingredient, is a peptide (a 
type of protein), which reduces the inflammatory responses within your skin cells, thus reducing 
eczema symptoms. In this study, AMTX-100 CF3 topical cream or placebo with 0% of active 
ingredient will be applied to the eczema affected areas of your skin twice daily for twenty-eight 
(28) consecutive days.  
 
This document uses words such as study treatment, study drug, medication, and participant. Please 
remember this is a research study and the use of these terms does not mean the use of AMTX-100 
CF3 has been found to be safe or effective for your condition. 
 
Why have I been chosen? 
 
You have been chosen for consideration for this study because you are diagnosed with atopic 
dermatitis (AD), also known as eczema, and your study doctor thinks that you might be a good 
candidate for this study, based on how severe and how large your skin areas are affected by AD.

In this study, about 60 participants with atopic dermatitis will enroll at about 20 sites within the 
United States. 
 
Do I have to take part? 
 
You do not have to take part in this study; it is completely voluntary. You will always be free to 
withdraw from the study at any time. If you withdraw during the study, you will be asked to 
come in for a final visit for study evaluations. You do not have to give a reason for your 
withdrawal from the study. This will not affect the standard of care that you will receive, and it 
will not result in any penalty or loss of benefits to which you are entitled. The data collected up 
to that point will be kept with your medical records and will be kept confidential. Your identity 
will not be disclosed. 
 
General Study Design and Duration of Study Involvement 
 
The duration of your participation in this study will be approximately up to ten (10) weeks and 
includes seven (7) in-clinic study visits to the study center. The study will be conducted in 3 
Parts. After the initial screening period (up to 4 weeks), you will enter study treatment period (28 
days), followed by the follow-up period (around 2 weeks).  
 
Screening Period: 
During this part of the study, you will be evaluated to determine if you would be eligible to enter 
the study. The Screening phase will take up to 4 weeks.  
 
Study Treatment Period: 
Participants who are determined to be eligible will enter the study treatment period of the study. 
During this part of the study, fifty-six (56) total doses of the study treatment (either AMTX-100 
CF3 topical cream, 1.1%,  or placebo) will be applied to all the AD-affected areas (except the 
scalp, face, eyes, eyelids, hands, palms, feet, groin, genitals or in the axillae) as instructed by the 
study doctor, in 1 dose applied twice daily for 28 consecutive days, regardless of whether your 
AD affected skin areas become better or clear. Study treatment period will be “Double-Blinded”, 
meaning that neither you nor the study doctor will know which study treatment group you have 
been randomly assigned to. 
 
At the first study visit of the study treatment period, you will be randomly assigned (by chance) 
to one of two (2) different groups to receive AMTX-100 CF3 topical cream (with 1.1% active 
ingredient of AMTX-100), or placebo (with no active ingredient) twice daily for 28 days. After 
the first visit of the study treatment period, you will be required to come to the study site for 
study visits once every week at weeks 1, 2, 3, and 4. 
 
At the week 4 Visit, all participants who have successfully completed study treatment period of 
the study will continue to the follow-up period of the study. 
 
Follow-up Period: 
After successful completion of the previous parts of the study, you will enter the follow-up period 
of the study to further assess how safe and whether the investigational drug AMTX-100 CF3 works

make any changes in your medications for atopic dermatitis unless instructed by the study 
doctor. In case your study doctor initiates any treatment for worsening symptoms of 
atopic dermatitis, ensure that you follow the treatment, instructed by the study doctor;  
• 
There will be no restriction of what you can eat during the study, unless food items are 
known to yourself or study doctor to trigger AD symptoms. 
• 
If you are a woman of childbearing potential, you must use an acceptable method of birth 
control (for example, diaphragm, intrauterine device (IUD), condom, hormonal 
contraceptives, or abstinence) during your participation in the study or be surgically 
sterile (for example, hysterectomy, bilateral tubal ligation, or bilateral oophorectomy), so 
that you do not become pregnant. If you are found to be pregnant after you receive first 
dose of study drug, your participation in the study will be terminated, but your pregnancy 
will be followed up to term to evaluate if there are any safety concerns with you or your 
child. 
•

This visit will take about 1-2 hours of your time. 
 
Withdrawal Visit: 
For participants who withdraw/are discontinued prematurely during study treatment period, 
“Withdrawal visit” assessments will be performed. Visit 6 assessments will be performed as the 
withdrawal visit evaluations. For all withdrawn/discontinued participants during study treatment 
period, the Follow-up visit (Visit 7) will happen 2 weeks after the withdrawal visit evaluations.  
 
What are the risks of taking part? 
 
AMTX-100 CF3 topical cream is still undergoing testing and there may be side effects that are 
unknown at this time.  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Animal and clinical studies have not indicated that AMTX-100 or AMTX-100 CF3 topical 
administration might be associated with allergic reactions. To reduce the risk of skin irritation, 
bathing the treated areas will be allowed once daily. Bathing/washing the treated areas in 
between morning and evening dose should be avoided within 8 hours after application and 
should be done at least every 3 days keeping normal daily hygiene. 
 
You will be monitored carefully during the administration of study drugs and will be watched 
carefully for side effects or any allergic reactions. As with any study drug, there is a risk of

allergic reaction. If you have a very serious allergic reaction, you may be at risk of death. Some 
symptoms of allergic reactions are: 
• 
Rash 
• 
Wheezing and difficulty breathing 
• 
Dizziness and fainting 
• 
Swelling around the mouth, throat or eyes 
• 
A fast pulse 
• 
Sweating 
You need to tell your study doctor or study staffs immediately if you experience any side 
effects, any unfavorable signs or symptoms. If any safety concerns arise, the study treatment 
may be stopped.  
 
Some redness, faintness, pain and swelling may happen due to the blood draws. You may 
experience bruising or bleeding at the site where the needle was placed. There is also a slight 
possibility of infection. 
 
If you do not understand what any of these side effects mean, please ask the study doctor or the 
study staff to explain them to you. 
 
It is unknown whether or not AMTX-100 CF3 topical cream will have any effect on unborn 
children or babies. It is unknown if AMTX-100 can pass through breast milk and it is unknown if 
this can cause harm to your child. This has not yet been investigated. Therefore, females who are 
pregnant or planning on becoming pregnant or who are breastfeeding will not be included in the 
study. If you are a woman of childbearing potential, you must use an acceptable method of birth 
control (for example, diaphragm, intrauterine device, condom, hormonal contraceptives, or 
abstinence) during your participation in the study or be surgically sterile (for example, 
hysterectomy, bilateral tubal ligation, or bilateral oophorectomy), so that you do not become 
pregnant. If you become pregnant during the study, please inform one of the study staff as soon 
as possible. Your pregnancy will be followed up to term. 
 
Your symptoms associated with atopic dermatitis may not get better or may become worse 
during this study. 
 
What are the possible benefits of taking part? 
 
You may or may not directly benefit from taking part in this study. The study treatment you 
receive may help to improve your atopic dermatitis symptoms. However, this cannot be 
guaranteed. The information that we get from this study may help us, and your study doctor, to 
treat future patients with this disease in a better way. 
 
Are there costs for participating?  
 
All study procedures will be provided at no charge to you. 
 
Reimbursement for study participation:

consent form. 
 
If you experience a side effect or injury that may be related to this study or if you have an 
unscheduled visit for medical care for any reason, please contact the study doctor listed on page 
one of this informed consent. 
 
If you claim to have become sick or injured from participating in this study, Amytrx 
Therapeutics, Inc. may give information that identifies you to its insurance carrier.  This 
information will be used by the insurance carrier solely for the purpose of resolving your claim. 
To pay medical expenses, the sponsor will need to know some information about you like your 
name, date of birth, and Medicare Beneficiary Identifier (MBI). This is because the sponsor has 
to check to see if you receive Medicare and if you do, report the payment it makes to Medicare. 
 
Will my taking part in this study be kept confidential? 
 
If you agree to take part in this study, your identity and medical records will be kept confidential 
and will not be disclosed outside of the hospital/study site/family physician’s office unless 
required by law. Your medical records may be inspected by Amytrx Therapeutics, Inc (the 
company sponsoring the study). Your records may also be inspected by a company Amytrx 
Therapeutics, Inc has delegated some study management to, Amarex Clinical Research, LLC. 
(Amarex), for purposes of analyzing the study results and monitoring the study. Regulatory 
authorities such as the U.S. Food and Drug Administration (FDA) and Institutional Review 
Boards (IRB) may review study results and participants records to check that the study is being 
conducted correctly. This means that absolute confidentiality cannot be guaranteed. If the results 
of this study are published or presented at meetings, you will not be identified. 
 
What if new information becomes available? 
 
During the course of a research study, new information may become available about your disease 
or the study treatment that is being studied that might change your decision to be in this study. If 
this happens, your study doctor will discuss this with you and whether you want to continue in 
the study. If you decide to withdraw, your study doctor will make arrangements for your 
prescribed standard conventional therapy to continue. If you decide to continue in the study you 
will be asked to sign and date an updated consent form. 
 
Also, on receiving new information your study doctor might consider it to be in your best interest 
to withdraw from the study. The study doctor will explain the reasons and arrange for your 
prescribed standard care to continue. 
 
What will happen to the results of the research study? 
 
Once the study has finished, the information will be analyzed, and a clinical study report will be 
written to record the results. This process can take about 6 months. Your study doctor will be 
kept informed of the results from the study, and a paper detailing these results will probably be

are entitled. Tell the study doctor if you are thinking about stopping or have decided to stop. The 
study doctor will tell you how to stop your participation safely.  
 
It is important to tell the study doctor if you are thinking about stopping your participation so 
that your study doctor can evaluate any risks from the study drug and discuss what alternative 
follow-up care and testing could be most helpful for you. If you withdraw during the study, you 
will be asked to come in for withdrawal visit, followed by safety follow up visit for safety 
reasons. Even if you don’t want to return for follow-up visits and blood tests, we would still like 
to collect information by phone or available medical records about your disease status.

Authorization to Use and Disclose Protected Health Information (HIPAA 
Authorization) 
 
While you are participating in this research study, the study doctor and his/her 
study staff will collect and create personal health information about you and record 
it on study forms. This information may include health histories, examinations, and 
results of tests. The study doctor will keep this information in study records. 
He/she may also gather information regarding your past, present, and/or future 
medical conditions from your primary medical doctor. These records may also 
include personal information such as your birth date, social security number, or 
medical record numbers which could be used to identify you. This type of 
information is called “Protected Health Information” (PHI). 
 
Under a United States federal law called the “Privacy Rule” or Health Insurance 
Portability and Accountability Act of 1996 (HIPAA), no one’s PHI that is gathered 
and obtained during research can be used to conduct the research or be given to 
anyone for research purposes without one’s permission. Because of this rule, you 
may not participate in this study unless you give your permission to use and 
disclose your PHI. 
 
By signing and dating this authorization, you are giving permission for the study 
doctor and his/her study staff, along with the Sponsor (Amytrx Therapeutics), 
Amarex Clinical Research (the Contract Research Organization) and the 
Regulatory authorities such as the U.S. Food and Drug Administration (FDA) and 
Institutional Review Boards (IRB) to use your PHI to conduct this study, to 
monitor your health status, and possibly to develop new tests, procedures, and 
commercial products.  
 
You are also agreeing to allow your PHI to be disclosed to the study sponsor and 
any representatives working with them. The sponsor may also give your PHI to the 
FDA or other regulatory agencies. Study staff will assign a code number to you for 
this study. This will help to protect your identity; however, the sponsor may look at 
your complete study records which will identify you. The sponsor will also send 
representatives to your study doctor’s office to oversee how the study is being 
conducted. These representatives will review your PHI to make sure the 
information is correct. The IRB may also have access to your PHI to meet its 
oversight responsibilities. These disclosures help to make sure that all information 
related to the research is available to those who need it.

Advarra IRB Approved Version 25/Jul/2023 
Revised «PIApprovalDate» 
 
Your identity will remain confidential, except for the disclosures described above 
and detailed specifically in the consent page, and will not be shared with others, 
unless it is required by law. If your PHI is given to the parties listed above or to 
anyone who is not required to follow federal law, your PHI will no longer be 
protected by the “Privacy Rule” and could possibly be used or disclosed in ways 
other than those listed here. 
 
You have the right to see and make copies of your PHI. You are agreeing, 
however, not to see or make copies of your PHI until all of the sponsor work has 
been completed. At that time, you may ask to see your records. 
 
Your HIPAA Authorization will expire 50 years from the date you sign it unless 
you revoke (cancel or withdraw) it sooner. You have the right to cancel or 
withdraw this authorization at any time. If you cancel this authorization, your PHI 
will no longer be used for this study, unless it is necessary (based on your earlier 
authorization) to complete analysis (tests) and reports for this research. 
 
To cancel your permission to use PHI, you must send a written notice to your study 
doctor’s office at the address listed on page one stating that you are canceling your 
authorization for them to use or disclose your protected health information. If you 
cancel this authorization, you will not be allowed to continue in this study. 
 
Participants will receive a signed and date copy of this document.

INTRODUCTION 
This Statistical Analysis Plan describes the planned analyses and reporting for part 2 of  the 
clinical trial protocol AMTX100-AD-01, conducted by Amytrx Therapeutics, Inc.. The 
reader of this Statistical Analysis Plan (SAP) is encouraged to review the complete protocol 
and amendments as this plan contains only a limited overview of protocol information.  
The main objectives of this plan are to provide details pertaining to statistical methodology, 
data conventions, and processes used for the analysis of data from this trial.  
The format and content of this SAP are structured to provide sufficient detail to meet the 
requirements specified by the International Council on Harmonization (ICH) E9: Guidance 
on Statistical Principles in Clinical Trials.  All work planned and presented in this Statistical 
Analysis Plan will follow the ethical guidelines published by the American Statistical 
Association (ASA). 
The following documents were reviewed in preparation of this Statistical Analysis Plan: 
• Final protocol Version 4.0/ 12 Jul 2023 
• ASA Ethical Guidelines for Statistical Practice (2016) 
• The Royal Statistical Society: Code of Conduct (2014) 
• ICH Guidance on the Structure and Content of Clinical Study Reports (ICH E3, 1996) 
• ICH Guidance on the Structure and Content of Clinical Study Reports (ICH E3(R1), 
2013)

PROTOCOL DESIGN 
2.1 
Design Overview 
This is an adaptive, Phase I/II study in 2 parts: Part 1 (Maximum Tolerable Dose (MTD) 
Finding by maximum percentage of BSA treated) and Part 2 (evaluating efficacy of 
AMTX-100 CF3 1.1% w/w versus placebo (vehicle)). The Part 1 of the study has been 
completed.  
Phase II (Part 2) Study Design 
Phase II (Part 2) of this study is a multi-center, double-blind, randomized, vehicle-
controlled study of the safety and efficacy of topically applied AMTX-100 CF3 in adult 
patients with Mild to Moderate AD. Sixty (60) subjects will be enrolled in two groups of 
AMTX-100 CF3 1.1% w/w and placebo (vehicle). The subjects will be randomized in a 
1:1 ratio, thus thirty (30) subjects will be randomized to Group A (AMTX-100 CF3 1.1% 
w/w) and thirty (30) subjects will be randomized to Group B (placebo (vehicle 0% w/w)). 
Each enrolled subject, after screening and randomization, will receive AMTX-100 CF3 
1.1% w/w or placebo (vehicle) to be applied twice daily to all treatable AD lesions 
regardless of whether the AD lesions become clinically clear or not (excluding the scalp, 
face, eyes, eyelids, hands, palms, feet, groin, genitals or in the axillae) for 28 consecutive
