Power and Sample
Size:
Cohort 1 will include approximately 6 evaluable subjects, which is
deemed adequate for the purpose of evaluating safety and PK prior to
Cohort 2.
There are approximately 215 subjects planned for Cohort 2.
Approximately 61 subjects will receive ARQ-252 cream 0.3% QD,
approximately 61 subjects will receive ARQ-252 cream 0.3% BID,
approximately 31 subjects will receive ARQ-252 cream 0.1% QD,
approximately 31 subjects will receive matching vehicle cream QD,
and approximately 31 subjects will receive vehicle cream BID.
The randomization scheme will be 2:2:1:1:1 between these
5 treatment groups, stratified by study site and IGA at Baseline.
The primary statistical comparisons will be to assess the ARQ-252
cream 0.3% BID group versus the vehicle BID group, to assess the
ARQ-252 cream 0.3% QD group versus the vehicle QD group, and to
assess the ARQ-252 cream 0.1% QD group versus the vehicle QD
group.
A sample size of 55 per active arm and 28 per vehicle arm will
provide approximately 85% power at the 2-sided 5% significance
level to detect a difference in the percent of subjects with IGA clear or
almost clear at Week 12; for each ARQ-252-treated group versus
vehicle group within the same daily dosing frequency, assuming an
active treatment response rate of 45% and a vehicle response rate of
15%, with a two-sided α = 0.1. This is based on a 2-group X2 test of
equal proportions (without continuity correction). With a 10%
dropout rate, the sample size for the study is increased to 61 subjects
per active arm and 31 subjects per vehicle arm (215 subjects total).
The primary statistical comparisons and evaluation of the secondary
endpoints will not be adjusted for multiplicity.
Statistical Analysis:
Descriptive statistics will be presented for the study endpoints. This
includes the number and percentage of subjects for binary
endpoints/categorical data, and mean, SD, median, minimum, and
maximum for continuous data.
The primary endpoint in Cohort 2 of ‘IGA clear or almost clear at
Week 12’ will be analyzed using a Cochran-Mantel-Haenszel test
stratified by study site and IGA at Baseline. The analysis will be
performed on the Intention-to-Treat (ITT) population and missing
data will be imputed using multiple imputation.
Continuous secondary endpoints measured in Cohort 2 will be
analyzed using Analysis of Covariance with treatment and
stratification factors as independent variables. The ITT population
will be used. Binary secondary endpoints will be analyzed similarly
to the primary endpoint.

INTRODUCTION
Background
Chronic hand eczema is a common condition which occurs in different forms. Chronic hand
eczema may significantly impact quality of life and cause significant costs, e.g., through inability
of patients to work. There is considerable unmet medical need for new therapies for hand eczema
since few treatments are available and/or approved specifically for hand eczema
(e.g., no FDA-approved therapies) and treatment is often unsatisfactory (Diepgen 2009).
Janus kinases (JAKs) are a family of intracellular nonreceptor tyrosine kinases that transduce
cytokine-mediated signals via the JAK-signal transducer and activator of transcription (STAT)
pathway and have a plethora of effects on the immune system, inflammation, and hematopoiesis.
In humans, the JAK family includes JAK1, JAK2, JAK3, and tyrosine kinase 2 (Tyk2). JAK1 is
a human tyrosine kinase which plays a critical role in initiating responses to multiple major
cytokines. It interacts with the common gamma chain of type I cytokine receptors to elicit signals
from the IL-2 receptor family, the IL-4 receptor family, the gp130 receptor family and other
cytokine receptor families. It is also important for transducing a signal by type I and type II
interferons, and members of the IL-10 family via type II cytokine receptors. JAK2 has been
implicated in signaling by the GM-CSF receptor family and controls various functions relating to
hematopoiesis. JAK3 is involved in signal transduction by receptors that employ the common
gamma chain of the type I cytokine receptor family (e.g., IL-2R, IL-4R, IL-7R, IL-9R, IL-15R,
and IL-21R) (Villarino 2017). Finally, Tyk2 is important for Th1 and Th17 responses,
transducing signals by interferons, IL-12, IL-23, IL-22, and IL-6 (O’Shea 2019).
The first demonstration of the clinical efficacy of JAK inhibitors in eczema utilized a topical
formulation of the pan-JAK inhibitor, tofacitinib, which has been approved orally for the
treatment of rheumatoid arthritis, psoriatic arthritis, and ulcerative colitis (Bissonnette 2016a).
Subsequently, several topical JAK inhibitors (delgocitinib, ruxolitinib) (Kim 2019;
Nakagawa 2018, Worm 2019) and oral JAK inhibitors (upadacitinib, PF-04965842, baricitinib)
(Guttman-Yassky 2019a; Gooderham 2019; Guttman-Yassky 2019b) have been reported to have
efficacy in the treatment of eczema. Oral JAK inhibitors can be accompanied by safety issues
including the development of opportunistic infections, lymphoma and other malignancies, and
hematologic and lipid abnormalities. We are pursuing development of ARQ-252 cream, a topical
form of the JAK1 selective inhibitor SHR0302, as a potential treatment for particular forms of
eczema aiming to maintain the efficacy of this class of agents in these diseases while minimizing
systemic exposure and undesirable side effects.
SHR0302 is in Phase 2 development as an oral therapy for rheumatoid arthritis (RA), Crohn’s
disease, ulcerative colitis, and atopic dermatitis by development partners Jiangsu Hengrui
Medicine Company (Hengrui) and Reistone Biopharma. Clinical safety data from these ongoing
programs, as well as extensive nonclinical studies, provide support for Arcutis’ dermal
(ARQ‑252) development program.

Nonclinical Safety Summary
In vitro pharmacology data supports that SHR0302 is a strong JAK inhibitor, with
JAK1>JAK2>JAK3> Tyk2 inhibitory activity. Additionally, SHR0302 has demonstrated
activity comparable to tofacitinib in various in vivo models of inflammatory conditions,
including the imiquimod-induced murine model of psoriasis, the oxazolone-induced murine
model of atopic dermatitis, the rat and murine models of collagen-induced arthritis, the
adjuvant-induced arthritis rat model, and the murine dextran sulfate sodium-induced colitis
model.
The nonclinical safety profile of orally administered SHR0302 has been well characterized
through the conduct of safety pharmacology, acute and repeat dose toxicity in rats and monkeys,
genetic toxicology (bacterial reverse mutation, in vitro micronucleus, in vivo micronucleus in
rats), and reproductive/developmental toxicology (fertility, embryofetal development) studies.
In safety pharmacology studies, SHR0302 did not cause significant changes in cardiovascular,
CNS or respiratory functions. After oral administration, SHR0302 was well absorbed and
distributed into many tissues.
During the oral dosing program of SHR0302 with dose levels up to 150 mg/kg/day in rats and
15 mg/kg/day in monkeys, the major target organs identified following repeated dosing were
immune system (lymph nodes, spleen, and thymus), bone marrow, reproductive organs and
digestive tract. As SHR0302 is a potent inhibitor of Janus kinases which are known to affect
cytokine-mediated signaling, the immunomodulatory effects observed (mainly in the rat) in the
toxicity studies are consistent with the pharmacological mechanism of action of SHR0302.
The genotoxicity studies on SHR0302 indicate a lack of potential to induce point mutations,
chromosomal aberrations, or to interact with or damage DNA. Therefore, it is unlikely that
SHR0302 poses a genotoxic risk to humans.
Results of a rat fertility study with SHR0302 showed no effects on male fertility and disrupted
early embryonic development in female rats at 10 and 50 mg/kg. The no observed adverse effect
level (NOAEL) was 50 mg/kg for male fertility and 1 mg/kg for female fertility and early
embryonic development. Embryofetal development studies in rats demonstrated maternal and
fetal toxicity and fetal teratogenicity following oral dosing of SHR0302. The NOAEL for rat
dams was 10 mg/kg and 1 mg/kg for embryofetal effects. In the rabbit embryofetal study, no
maternal toxicity was noted at the high dose of 25 mg/kg/day (NOAEL). Rabbit embryo-fetal
developmental toxicity was noted with effects on fetal viability and development, including fetal
visceral and/or skeletal malformations and resulting in a NOAEL of 1 mg/kg/day.
The nonclinical safety profile of SHR0302 was also evaluated topically in mice and minipigs in
support of once-daily topical administration. Dermal toxicology studies conducted to date
include 13-week mouse, 7-day tolerability in minipigs, 4-week and 16-week toxicity in minipigs,
and local tolerance (ocular irritation, skin sensitization, in vitro phototoxicity). Planned studies
include 39-week toxicity in minipigs and a 104-week carcinogenicity study in mice.

The dermal toxicity of ARQ-252 (SHR0302 cream) has been evaluated and no new risks have
been identified and no target organs were identified. In the 13-week dermal toxicity study in
mice and the 7-day and 16-week dermal toxicity studies in minipigs, no evidence of systemic
toxicity was observed, and no dermal findings were noted. The NOAELs in each of these repeat
dose dermal toxicity studies were the highest doses administered.
Local tolerance studies demonstrated ARQ-252 is not a skin sensitizer or eye irritant, and it does
not have phototoxic potential.
Overall, the results suggest that topical ARQ-252 cream is safe and well tolerated in both mice
an minipigs. Taken together, the results of the nonclinical toxicology studies demonstrated an
acceptable topical safety profile and support the progression of ARQ-252 cream into clinical
studies in patients with hand eczema.
Clinical Studies
This will be the first study of topical ARQ-252 cream in the human population.
Oral administration of SHR0302 has been studied in three Phase 1 pharmacokinetic studies,
including two conducted in healthy volunteers and one conducted in subjects with rheumatoid
arthritis. Oral administration of SHR0302 has also been studied in a 24-week, Phase 2 study in
subjects with rheumatoid arthritis.
Oral Administration: Phase 1
In three Phase 1 pharmacokinetic studies, a total of 94 subjects were exposed to SHR0302 at
various dosages and duration. The single maximum dose of exposure in humans was 100 mg,
and the longest duration of exposure was 7 days of 10 mg SHR0302 in rheumatoid arthritis
patients.
A study on human safety, pharmacokinetics, and pharmacodynamics was conducted on
SHR0302 following single dose oral administration in healthy subjects (SHR0302-101).
This was a randomized, double blind and placebo-controlled study with six dosage groups of
1, 5, 10, 25, 50 and 100 mg. AEs were reported mainly from the high-dose groups (50 mg and
100 mg) in this single ascending dose study. The most common AEs involved the hematologic
system (neutropenia and high lymphocyte count). Adverse reactions included neutropenia in
7 subjects (10.9%), elevated lymphocytes in 6 subjects (9.4%), and leukopenia in 1 subject
(1.6%). At the 25 mg dose and below, there was no obvious difference between the active and
placebo arms. There were no serious adverse events.
Following single oral dose administration, SHR0302 was rapidly absorbed with median Tmax
values of 1.0 hour across all dose groups. Geometric mean Cmax values increased 105-fold over
the 100-fold increase in dose (1 to 100 mg), demonstrating dose proportional kinetics. Similarly,
the geometric mean AUC0-24 values increased 107-fold over the same 100-fold increase in dose.

A multiple ascending dose (MAD) study of human safety, pharmacokinetics, and
pharmacodynamics was conducted on orally administered SHR0302 in subjects with rheumatoid
arthritis (SHR0302-102). This was a randomized, double-blind, and placebo-controlled study
with four planned dosage groups of 2, 5, 10 and 25 mg. Each dosage group had 12 subjects,
10 receiving active and 2 receiving placebo. Subjects were dosed for 7 days. The 2, 5, and 10 mg
dose groups were completed, for a total of 36 subjects, 30 receiving active drug. No subjects in
the 25 mg dose group were enrolled.
Twenty out of 36 subjects experienced AEs during the study period, with 16 subjects
experiencing AEs reported as causally related to drug. AEs reported in subjects exposed to
SHR0302 included seven cases of elevated TSH, five cases of elevated alanine aminotransferase,
four cases of elevated aspartate aminotransferase, three cases of anemia, three cases of urinary
tract infection, two cases of lowered free thyroxine, and one case each of ear pain, conjunctivitis,
hypoesthesia, constipation and hematuria. Elevated TSH in blood (five cases), urinary tract
infection (three cases) and lowered free thyroxine (two cases) were concentrated in the 10 mg
SHR0302 group. All AEs were Grade 1 or Grade 2, and most reversed within two weeks of drug
discontinuation. No SAEs were reported. Study drug dose was not decreased or suspended in
any subject due to an AE, and no subject withdrew from the trial due to an AE.
Following multiple oral dose administrations of SHR0302, the median Tmax value was 1.0 hour
across the dose groups. Geometric mean Cmax values increased 3.5-fold over the 5-fold increase
in dose (2 to 10 mg), demonstrating less than dose proportional kinetics. Similarly, the geometric
mean AUC0-24 values increased 4.1-fold over the same 5-fold increase in dose from
1130 hr*ng/mL for the 2 mg dose to 4620 hr*ng/mL for the 10 mg dose.
A food effect study of high-fat intake on the pharmacokinetics of SHR0302 has also been
conducted (SHR0302-103). In this study, SHR0302 (10 mg tablet) was safe and well tolerated in
healthy subjects, and administration of SHR0302 after a high-fat meal did not significantly
impact systemic exposure. Except for one AE (soft tissue contusion) unrelated to drug which
was moderate, the other AEs were mild and recovered without treatment. No SAEs were
reported, and no subject withdrew from the trial due to an AE.
Overall, SHR0302 was well-tolerated with no SAEs reported.
Oral Administration: Phase 2
Preliminary results are available from SHR0302-201, a Phase 2, double-blind, randomized study
evaluating 0.5 mg, 1 mg, 2 mg, 4 mg, and 8 mg of SHR0302 as once-daily oral monotherapy for
adults with active rheumatoid arthritis who were naïve to any disease modifying anti-rheumatic
drug (DMARDs) or have had an inadequate response or intolerance to conventional synthetic
DMARDs. The study was placebo-controlled for 12 weeks, followed by a 12-week, open label
maintenance phase. The Primary Endpoint was the response rate of American College of
Rheumatology 20 (ACR20) at Week 12, which is a composite measure defined as 20%
improvement in the number of tender and swollen joints, and 20% improvement in 3 of 5 criteria
including patient global assessment, physician global assessment, functional ability measure,

Preliminary safety results include:
•
SHR0302 was generally safe and well tolerated. A higher frequency of infections was
observed in SHR0302-treated subjects, particularly in the 8mg group. The most common
infections included upper respiratory tract infections and urinary tract infections.
•
Mean WBC, neutrophils, lymphocyte, HGB, platelet count, serum lipid level, liver
function, kidney function, and thyroid function parameters remained in the normal range
in all SHR0302 treatment groups.
•
Mean platelet count did not increase during the study.
•
Increases in LDL, HDL, total cholesterol and triglycerides were observed. However,
LDL-to-HDL remained stable.
•
Increase in mean serum creatine kinase (CK) was observed in patients treated with
SHR0302 versus placebo but was within normal range. CK-MB remained stable.
•
Most of the reported abnormal laboratory results were classified as CTCAE grade 1 or 2.
CTCAE grade 3 events included: 1 case of increased alanine aminotransferase (4 mg),
1 case of decreased neutrophils (8 mg), 1 case of decreased lymphocytes (4 mg) and
1 case of anemia (8 mg).
•
From Baseline through Week 12, the most common AEs (≥5% across pooled SHR0302
groups) included upper respiratory infection, hyperlipidemia, swollen joint, urinary tract
infection, hypercholesterolemia, joint pain, and cough. From Baseline to Week 12, other
TEAEs occurring at rates ≥5% in individual SHR0302 groups (although <5% across
pooled SHR0302 groups) included hypothyroidism, anemia, liver dysfunction (although
placebo group had highest rate), elevated serum creatine phosphokinase, diarrhea,
headache, hematuria, abdominal discomfort, urine protein detection, blood in urine,
elevated blood lactic dehydrogenase, and upper abdominal pain. Additional common
AEs (≥5% across pooled SHR0302) seen from Baseline through Week 24 included
elevated serum creatine phosphokinase, anemia, and hypothyroidism.
•
Overall, there were 6 severe AEs in 3 subjects including 4 severe SAEs in a subject in the
0.5 mg group during the placebo-controlled period (Craniocerebral injury, Ventricular
hemorrhage, Occipital fracture and Subarachnoid hemorrhage), appendicitis in a subject
in the 4 mg group during the placebo-controlled period, and elevated liver enzymes in a
subject in the 4 mg group during the extension period.
•
AEs leading to discontinuation were generally uncommon from Baseline through
Week 12 (1 or fewer subjects per group). From Baseline through Week 24, AEs leading
to discontinuation remained generally uncommon (1 or fewer subjects per group, except
for 3 subjects in the 4 mg group, and 3 subjects in 8 mg group including 1 subject in
placebo group then received 8 mg after Week 12).
•
A total of 4 cases of herpes zoster (all in 8 mg group) and 1 case of opportunistic
infection (8 mg group, cryptococcal pneumonia) were reported.
•
No tuberculosis, malignancy, important cardiac events or death were reported.
•
One thrombotic event was reported, a SAE of multiple lacunar infarcts in a 64 year-old
woman in the 0.5mg SHR0302 group, requiring hospitalization, deemed unrelated, with
dose not changed.

•
From Baseline through Week 12, there were 13 SAEs in 9 subjects overall, including
3 SAEs in 2 subjects in the placebo group, 5 SAEs (Craniocerebral injury, Ventricular
hemorrhage, Occipital fracture and Subarachnoid hemorrhage; Lacunar infarction) in
2 subjects in the 0.5 mg group, 3 SAEs (Hemorrhoids; Pulmonary infection;
Appendicitis) in 3 subjects in the 4 mg group, and 2 SAEs (Epiglottic cyst; Tympanitis)
in 2 subjects in the 8 mg group. From Week 12 through Week 24, there were 4 SAEs in
3 subjects, including Liver dysfunction in a subject in the 4 mg group, Viral
gastroenteritis in a placebo-8 mg subject, and Cryptococcal pneumonia and Ureterolith in
a subject in the 8 mg group.
Additional Studies
An open label, self-controlled study (SHR0302-105) evaluating drug interaction potential
between SHR0302 and methotrexate (MTX) in subjects with rheumatoid arthritis was recently
completed. Subjects were to take MTX 10 mg once daily on Day 1 and Day 8, and SHR0302
10 mg once daily on Days 3 to Day 8. Overall, 15 subjects were enrolled. A total of 18 adverse
events were reported in 8 of 15 subjects (53.3%). Of the 18 adverse events, 3 subjects (20.0%)
reported 5 adverse events after SHR0302 alone, 4 subjects (26.7%) reported 5 adverse events
after MTX alone, and 3 subjects (20.0%) reported 8 adverse events after MTX and SHR0302 in
combination. The adverse events reported in subjects given SHR0302 alone included headache,
back pain, fever, constipation and tachycardia each in 1 subject (6.7%). The adverse events
reported by the subjects after MTX and SHR0302 in combination included anemia, upper
respiratory tract infection, urinary tract infection, elevated blood triglycerides, elevated aspartate
aminotransferase, positive urine leukocytes and tachycardia each in 1 subject (6.7%). No serious
adverse events were reported, and no subjects withdrew prematurely due to adverse event.
Ongoing Studies
Two studies of SHR0302 as an oral treatment of inflammatory bowel disease are ongoing.
RSJ10101 is a phase 2, randomized, placebo-controlled, double-blind, 4 arm, dose-ranging
study to evaluate the efficacy and safety of SHR0302 compared to placebo in adults with
moderate to severe, active ulcerative colitis. Treatment groups include 3 different doses of
SHR0302 (4mg QD, 8mg QD, 4mg BID) or placebo, with 1:1:1:1 randomization. The study
consists of an 8-week blinded treatment phase, followed by an 8-week of blinded, active
extension phase. Planned enrollment is 152 across China, Ukraine, United States, and Poland.
RSJ10201 is a phase 2, randomized, placebo-controlled, double-blind, four arms dose-ranging
study to evaluate the efficacy and safety of SHR0302 compared to placebo in adults with
moderate to severe, active Crohn’s disease. Treatment groups include 3 different doses of
SHR0302 (4mg QD, 8mg QD, 4mg BID) or placebo, with 1:1:1:1 randomization. The study
consists of a 12-week blinded treatment phase, followed by a 12-week of blinded, active
extension phase. Planned enrollment is 144 across China, Ukraine, United States, and Poland.
Analysis of blinded data from these two ongoing studies in IBD (RSJ10101 and RSJ10201) as of
October 19, 2019 has been performed. Based on this analysis, 39 subjects were estimated to be
exposed to SHR0302 in these two clinical trials. One SAE was reported as colitis ulcerative and
the other one was synovitis. The latter SAE was unblinded and confirmed to be on SHR0302.

Overall, the reported safety data were in line with the known and expected safety profile of
SHR0302.
Finally, two additional studies of SHR0302 recently started, for which no data is currently
available. RSJ10303 is a phase 2 study in China of SHR0302 in atopic dermatitis. The study is
a randomized, double-blind, and placebo-controlled, evaluating the efficacy and safety of
SHR0302 4mg QD, SHR0302 8mg QD, or placebo in adult patients with moderate to severe
atopic dermatitis. RSJ10411 is a phase 1, vehicle-controlled study in Australia and China to
evaluate the safety and pharmacokinetics of SHR0302 base ointment at single dose and multiple
dose in healthy adult subjects.
Rationale for Development
Since the first demonstration of the clinical efficacy of JAK inhibitors for the treatment of
eczema, which utilized a topical formulation of tofacitinib for the treatment of atopic dermatitis,
numerous oral JAK inhibitors and several other topical JAK inhibitors have also demonstrated
efficacy in eczema. We are pursuing the development of ARQ-252 cream as a topical
JAK1-selective inhibitor for the treatment of hand eczema, planning to take advantage of the
efficacy of this class of agents in this disease, while minimizing systemic exposure and
undesirable side effects. Nonclinical and systemic clinical data with SHR0302 to date are
supportive of this plan.
The above data indicate that topical ARQ-252 could provide an important addition to the
dermatologist’s approach for treating hand eczema.
Dose Selection
ARQ-252 cream 0.3% was selected as the high clinical dose because this dose remains in
solution when stored at controlled room temperature.
In Cohort 1 of this study, ARQ-252 cream 0.3% will be applied QD to approximately 4% BSA
in subjects with hand eczema. It is well known that cutaneous disease states can alter drug
permeability as compared to normal human skin. Since eczematous skin may have different drug
permeability characteristics than normal skin (Ortiz 2009; Halling-Overgaard 2017), this study is
planned in patients with hand eczema rather than healthy volunteers. Administration of
ARQ‑252 cream 0.3% once-daily to approximately 4% of BSA at an application rate of
approximately 0.75 mg/cm2 would result in 1.5 mg of total SHR0302 being absorbed per day,
assuming 100% absorption of applied drug, an amount well covered by the oral MAD study
discussed previously (Section 2.3.1). In the oral MAD, daily doses of 2 to 10 mg resulted in
signals for thyroid effects (elevated TSH, decreased free T4), mild LFT abnormalities, and a few
urinary tract infections. These are all easily monitored, and skin absorption is very likely to be
only a small fraction of 100%. Moreover, in the Phase 2 RA study, mean WBC, neutrophils,
lymphocyte, HGB, platelet count, liver function and kidney function remained in the normal
range in all SHR0302 treatment groups.

Following a review of safety and PK data from Phase 1 (Cohort 1) of this study, Phase 2b
(Cohort 2) can commence. Phase 2b (Cohort 2) is a parallel group, double blind,
vehicle-controlled cohort in which subjects with chronic hand eczema will be randomized to
ARQ-252 cream 0.3% QD, ARQ-252 cream 0.3% BID, ARQ-252 cream 0.1% QD, vehicle
cream BID or vehicle cream QD.
Risks and/or Benefits to Subjects
The potential risks of ARQ-252 cream stem from what is known about the safety of the oral form
of this drug, and risks associated with the JAK inhibitor mechanism. These risks include serious
infections, other infections (e.g., upper respiratory tract infections, opportunistic infections,
herpes), anemia, lymphopenia, natural killer (NK) cell reduction, neutropenia, platelet elevations
or reductions, malignancy and lymphoproliferative disorders, gastrointestinal perforations, liver
function abnormalities, thyroid function abnormalities, lipid elevation, serum creatinine
elevations, creatine phosphokinase elevations, thrombosis, nausea, diarrhea, headache, and
hypertension. In general, topical delivery is expected to carry lower risk than oral administration
at therapeutic doses to the degree that systemic exposure is reduced. Previous nonclinical
research showed that the active ingredient in ARQ-252 can harm fetal development. Please refer
to the Investigator’s Brochure for detailed information.
Phase 1 (Cohort 1)
Subjects in Cohort 1 subjects may see an improvement in their hand eczema, although the study
duration of 2 weeks may limit this possibility.
Phase 2b (Cohort 2)
Subjects randomized to active treatment in Cohort 2 may see an improvement in their hand
eczema with the use of ARQ-252 cream. Those receiving vehicle cream may also see
improvement related to the moisturizing properties of the vehicle
The safety monitoring practices employed in this protocol (i.e., physical examinations,
application site reaction assessments, hematology, serum chemistry, TSH, T4, urinalysis, ECG,
and AE questioning) are adequate to protect the subjects’ safety and should detect expected AEs.

INVESTIGATIONAL PLAN
Overall Study Design and Plan
This is a phase 1/2b, multiple dose and 12-week, parallel group, double blind, dose ranging,
vehicle-controlled study of the safety and efficacy of ARQ-252 cream 0.1% and ARQ-252 cream
0.3% in subjects with chronic hand eczema.
There are 2 cohorts of subjects:
•
Cohort 1 is a multiple dose cohort in which subjects with chronic hand eczema will be
assigned to ARQ-252 cream 0.3% QD x 2 weeks to be applied to both hands. PK and
tolerability will be evaluated.
•
Cohort 2 is a parallel group, double blind, vehicle-controlled cohort in which subjects with
chronic hand eczema will be randomized to ARQ-252 cream 0.3% QD, ARQ-252 cream
0.3% BID, ARQ-252 cream 0.1% QD, vehicle cream BID or vehicle cream QD x 12 weeks
to be applied to both hands. Safety and efficacy will be evaluated.
Number of Sites and Subjects
A total of approximately 6 evaluable subjects will be enrolled in Cohort 1 and a total of
approximately 215 subjects will be enrolled in Cohort 2. Approximately 45 study sites are
planned in the US, Canada and Australia. During the conduct of the study, additional countries
and/or sites may be added if necessary. Subjects will be adults (≥18 years of age) males or
females with chronic hand eczema.
For Cohort 1, evaluable subjects are defined as those that:
•
Complete 2 weeks of treatment


Protocol ARQ-252-205

Page 35 of 72
•
Have PK results for all timepoints required at D1, D2, D15 and D16.
Unevaluable subjects in Cohort 1 may be replaced. Subjects in Cohort 2 will not be replaced.
Subject Participation
Phase 1 (Cohort 1)
Subject participation involves a minimum of 7 clinic visits including Screening, Baseline/Day 1,
Day 2, Day 8, Day 15, Day 16 and Day 22. Subjects will be treated with investigational product
(ARQ-252 cream 0.3% QD) for 2 weeks. The interval between the Screening and Baseline visits
could be up to 4 weeks, therefore the anticipated maximum duration of subject participation is
7 weeks.
Phase 2b (Cohort 2)
Subject participation involves a minimum of 7 clinic visits including Screening, Baseline/Day 1,
Week 2, Week 4, Week 8, Week 12 and Week 13. Subjects will be randomized to a treatment
group and will be treated with investigational product for 12 weeks. The interval between the
Screening and Baseline visits could be up to 4 weeks, therefore the anticipated maximum
duration of subject participation is 17 weeks.
Randomization
Phase 1 (Cohort 1)
Phase 1 (Cohort 1) is open label and all enrolled subjects will be assigned treatment with
ARQ‑252 cream 0.3% QD at the Baseline visit. Subjects will be enrolled at the Baseline visit
after the Investigator confirms that the subject meets all eligibility criteria listed in Section 4.7.
Enrollment will be documented by the completion of the Enrollment Notification Form.
Phase 2b (Cohort 2)
Phase 2b (Cohort 2) is randomized. Randomization will take place at the Baseline visit after the
Investigator confirms that the subject meets all eligibility criteria listed in Section 4.7. Subjects
will be randomly assigned to apply ARQ-252 0.3% QD, ARQ-252 0.3% BID, ARQ-252 0.1%
QD, vehicle cream QD or vehicle cream BID by an interactive response technology system
(IRT).
Assignment of treatment arm will be made at a 2:2:1:1:1 ratio and stratified by study site and
IGA at baseline according to a computer-generated randomization list. Kits containing tubes of
investigational product will be assigned to each subject by the IRT system. A subject may
receive more than one kit for the treatment period. The kits and tubes will be labeled with a
unique number, in a blinded manner.

Numbering of Subjects
Phase 1 (Cohort 1)
All subjects who sign informed consent will be assigned a unique six-digit subject ID number by
the site. The first three digits will correspond to the site number (assigned by the Sponsor) and
the next three digits correspond to the sequential order in which the subject is screened for the
study.
Phase 2b (Cohort 2)
All subjects who sign informed consent will be assigned a unique six-digit subject ID number by
the IRT system. The first three digits correspond to the site number (assigned by the Sponsor),
the next three digits correspond to the sequential order in which the subject is screened for the
study.
The clinical site is responsible for maintaining a current log of subject ID number assignments
and the kit number assigned to that subject. The subject ID number is required to be entered on
all clinical study documentation (e.g., case report forms, labeling of clinical materials and sample
containers, investigational product accountability logs, etc.).
Blinding
Phase 1 (Cohort 1) is not blinded.
Phase 2b (Cohort 2) is double-blinded, therefore neither the subjects nor the Investigator and
clinical personnel will be aware of which investigational product (ARQ-252 0.1% cream,
ARQ‑252 0.3% cream or vehicle cream) an individual subject receives. The subjects,
Investigator and clinical personnel will be aware of whether IP is to be applied QD (once daily)
or BID (twice daily).
Breaking Treatment Codes
Phase 2b (Cohort 2)
In the event of a medical emergency where breaking the blind is required to provide medical care
to the subject, the Investigator may obtain treatment assignment directly from the IRT system for
that subject. Refer to the current version of the IRT plan for details on unblinding. Treatment
assignment should, however, remain blinded unless the assignment knowledge is necessary to
determine subject emergency medical care. The rationale for unblinding must be clearly
explained in source documentation and on the CRF, along with the date on which the treatment
assignment was obtained. The Investigator is requested to contact the Sponsor promptly in the
event of any treatment unblinding.
Blinding of study treatment is critical to the integrity of this clinical trial and therefore, if a
subject’s treatment assignment is disclosed to the Investigator, the subject will have the study
treatment discontinued. All subjects will be followed until study completion unless consent to do
so is specifically withdrawn by the subject.

or higher)
As noted above, study treatment must be discontinued immediately in the event of a female
subject’s pregnancy.
Treatment should be interrupted:
•
If a subject develops an application site reaction with the clinical appearance of an
‘irritation reaction’, and with a severity of a Dermal Response Score of 5 (erythema,
edema and papules) or greater on the scale of Berger and Bowman, treatment should be
interrupted for up to one week and may then be resumed if the reaction has, in the
opinion of the Investigator, adequately resolved.

Treatment Administration
Initial treatment with the IP will occur on Day 1. At the Baseline visit the study staff will
demonstrate to the subject how to apply IP using the first tube that is assigned to the subject at
enrollment/randomization. Study site staff will demonstrate how two unit doses (two pea size
amounts of IP will cover approximately 4% BSA, i.e., both hands entirely) are properly squeezed
from the tube and applied as a thin film to cover both hands. IP will be applied to the front and
back of both hands, interlacing fingers, rubbing in thoroughly but gently, until the cream has
absorbed. The subject will then practice squeezing a similar amount and applying IP. The study
staff will confirm that the subject’s application technique is correct.
Subjects in Cohort 1 will be instructed to apply IP once daily (QD). Subjects in Cohort 2 will be
instructed to apply IP either once daily (QD) or twice daily (BID), as determined at
randomization.
IP tubes must be returned by subjects at each study visit, both empty and full, and will be
weighed. Re-training will be conducted at subsequent visits as needed (i.e., if the returned tube
weighs substantially different than the expected weight).
Subjects will be instructed to refrain from handwashing for 4 hours after IP application, if
possible. Subjects may use hand sanitizer within 4 hours of IP application, if necessary.
Hand washing and use of hand sanitizer within 4 hours of IP application will be recorded in the
subjects’ diary and CRF.
Treatment Compliance
Each IP tube will be weighed prior to dispensing at the Baseline visit and at each follow-up
clinic visit according to the Schedule of Visits and Assessments (Section 1.3). When IP is
applied in the clinic, the IP tube will be weighed before and after IP application. If the subject’s
actual use is substantially different than the expected use (see IP Handling Plan), the subject will
be retrained on the investigational product application technique.
Subjects will complete a daily diary recording the date and time of each dose applied, any missed
doses, and a comment section should the subjects have a comment, e.g., record potential AEs,
handwashing or use of hand sanitizer within 4 hours. Site personnel will review the diaries and
use the information to question the subject regarding compliance and AEs and then record
appropriate information in source documents and complete CRFs. If a subject misses a dose,
they should be instructed to return to the protocol investigational product administration schedule
(i.e., if subject forgets a dose they should wait until the next planned application and apply as
usual).
A subject will be considered compliant with the dosing regimen if the subject applies at least
80% of the expected applications during the investigational product application period and does
not miss more than 3 consecutive doses.

Compliance will be assessed by review of the dosing diary. Weight of investigational product
applied will be measured for reporting purposes.
If the diary shows less than 80% of expected use, the subject is using too little investigational
product and retraining must be conducted and documented.
Compliance will be documented in source and in CRF.

STUDY PROCEDURES
Safety Assessments
The Schedule of Visits and Assessments (Section 1.3) summarizes the clinical procedures to be
performed at each visit. Individual clinical procedures are described in detail below. Additional
evaluations/testing may be deemed necessary by the PI and/or the Sponsor for reasons related to
subject safety.
This study assesses the safety, efficacy, and PK of ARQ-252 cream 0.1%, ARQ-252 cream 0.3%
and vehicle cream. Safety will be determined by evaluating physical examinations, 12-lead
ECGs, vital signs/weight, clinical laboratory parameters, local tolerability assessments, and AEs
as outlined in the Schedule of Visits and Assessments (Section 1.3). If deemed necessary,
additional safety assessments will be performed at the discretion of the Investigator.
Screening
Before a subject’s participation in the clinical study, the Investigator is responsible for obtaining
written informed consent from the subject after adequate explanation of the study design,
anticipated benefits, and the potential risks. A subject is considered a participant of the trial once
the ICF is completely signed.
The following procedures/assessments will be performed at the Screening Visit (within 4 weeks
after signing the informed consent):
•
Review of medical and surgical history, including any history of allergies and/or contact
dermatitis
•
Review of childbearing potential (subject or partner of male subject) and contraceptive
use (see Section 5.1.2)
•
Collection of demographic data including sex, age, race, ethnicity
•
Vital signs including temperature, heart rate, and blood pressure
•

in Cohort 2 will be entered into the IRT system at the time of consent.
Subjects may be re-screened one time, the original assigned Subject ID screening number will be
used for re-screening.
Contraception Requirements
Previous nonclinical research showed that the active ingredient in ARQ-252 can harm fetal
development. Subjects engaging sexual intercourse that could lead to pregnancy must adhere to
the following pregnancy testing and/or contraception requirements.
Female Subjects
Female subjects of childbearing potential (FOCBP) must have a negative serum pregnancy test at
Screening and negative urine pregnancy test at Baseline (Visit 2). For FOCBP involved in any
sexual intercourse that could lead to pregnancy: the subject must agree to use a highly effective
contraceptive method for at least 4 weeks prior to Day 1. Additionally, from Day 1 until at least
4 weeks after the last investigational product administration, these subjects must agree to use at

Local Tolerability Assessment
The Investigator Local Tolerability Assessment will be performed according to the Schedule of
Visits and Assessments (Section 1.3).
Application site reactions will be graded at the timepoints outlined in the Schedule of Visits and
Assessments (Section 1.3). Irritation reactions are graded using the scale detailed in the
following section (Berger 1982). Reactions at the site of product application, which may
occur post-Baseline, should be differentiated from the preexisting inflammation associated
with the subject’s chronic hand eczema.
The Investigator assessments will be conducted by the Investigator prior to investigational
product application in the clinic.
Dermal Response
0 = no evidence of irritation
1 = minimal erythema, barely perceptible
2 = definite erythema, readily visible; minimal edema or minimal papular response
3 = erythema and papules
4 = definite edema
5 = erythema, edema and papules
6 = vesicular eruption
7 = strong reaction spreading beyond application site
Other Effects
A = slight glazed appearance
B = marked glazing
C = glazing with peeling and cracking
D = glazing with fissures
E = film of dried serous exudates
F = small petechial erosions and/or scabs
G = no other effects
The Subject Local Tolerability Assessment will be performed according to the Schedule of Visits
and Assessments (Section 1.3).
This assessment will be administered by the site 10 to 15 minutes after investigational product
application in the clinic.

For further details on Adverse Events please see Section 5.7.
Efficacy Evaluations
Investigator’s Global Assessment (IGA)
Investigator’s Global Assessment of chronic hand eczema will be performed according to the
Schedule of Visits and Assessments (Section 1.3).
The IGA is a static evaluation of qualitative overall chronic hand eczema severity. This global
assessment scale is an ordinal scale with five severity grades (reported only in integers of 0 to 4).
Each IGA Severity Score is defined by distinct and clinically relevant morphologic descriptions
that minimizes inter-observer variability.
Every effort must be made for the same Evaluator to complete the IGA for the subject at
every study visit.
IGA will be assessed at clinic visits prior to the subject applying Investigational Product
and other physician assessments.

performed according to the Schedule of Visits and Assessments (Section 1.3).
Subjects will complete the WI-NRS pruritis assessment in the clinic during Screening and then
daily at home from the Baseline/Day 1 visit until the last visit. Subjects will record their
WI-NRS on a diary and will return the diary to the clinic at each visit. Sites will review WI-NRS
entries and enter into the CRF.
The WI-NRS has been developed as a simple, single item to assess the patient-reported severity
of this symptom at its highest intensity during the previous 24-hour period. (Naegeli 2015).
The WI‑NRS will be determined by asking the subject’s assessment of worst itch over the past
24 hours. The scale is from ‘0 to 10’ (“no itch” to “worst imaginable itch”).

The NRS-Pain Scale is the most widely used instrument for pain screening. Subjects will select
the number between 0 and 10 that fits best to their worst pain intensity over the past 24 hours,
where 0 represents ‘no pain at all’ and 10 ‘the worst pain possible’.

HECSI
The Hand Eczema Severity Index (HECSI) will be performed according to the Schedule of Visits
and Assessments (Section 1.3).
HECSI is an instrument used in clinical trials to rate the severity of 6 clinical signs of hand
eczema and the extent of the lesions on each of 5 hand areas by use of standard scales. The total
HECSI score is based on a 4-point severity scale ranging from 0 (none/absent) to 3 (severe) and
a 5-point scale rating the affected area(s) ranging from 0 (0% affected area) to 4 (76% to 100%
affected area).

from 0 to 4: (0, 0%; 1, 1-25%; 2, 26-50%; 3, 51-75%; 4, 76-100%) for the extent of clinical symptoms. Finally the
score given for the extent for each location was multiplied by the total sum of the intensity of each clinical feature
(each contributing equally to the final score) and the total sum called the HESCI score was calculated, varying from
0 to a maximum severity score of 360 points.

Quality of Life in Hand Eczema Questionnaire
The Quality Of Life in Hand Eczema Questionnaire (QOLHEQ) will be performed according to
the Schedule of Visits and Assessments (Section 1.3) in Phase 2b (Cohort 2). The QOLHEQ is
an instrument to assess disease specific Health Related Quality of Life (HRQOL) in patients
suffering from hand eczema (Appendix 1). The construct HRQOL includes all impairments or
limiting conditions caused by the health state of an individual. The QOLHEQ is a disease
specific instrument, thereby only assessing impairments caused by hand eczema. It consists out
of 30 items which can be summarized according to four domains of HRQOL: Impairments
because of (1) symptoms, (2) emotions, (3) limitations in functioning or (4) because of treatment
and prevention.
Nail Dystrophy Assessment
Phase 2b (Cohort 2)
A Nail Dystrophy Assessment will be performed in Cohort 2 according to the Schedule of Visits
and Assessments (Section 1.3) to identify any alteration of nail morphology. Assessment to
include the following evaluations by the Investigator:
Baseline/Day 1:
•
Does the subject have at least one nail with significant dystrophy extending to the
cuticle? Yes/No
•
If “Yes”, record which nail has the worst dystrophy (indicating left or right)
Subsequent visits according to the Schedule of Visits and Assessments:
•
For the identified fingernail with the worst dystrophy at Baseline/Day 1, is there normal
appearing nail distal to the cuticle, Yes/No
•
If “Yes”, how many millimeters of normal appearing nail distal to the cuticle?
Sites participating in optional photography will obtain photos of nail with the worst dystrophy at
Baseline/Day 1 and at subsequent visits according to the Schedule of Visits and Assessments
(Section 1.3) and Section 5.3.2.
Other Evaluations
Pharmacokinetics Assessment
PK draws will be performed according to the Schedule of Visits and Assessments (Section 1.3)
for all subjects at all sites.
Phase 1 (Cohort 1)
•
Serial PK sampling will be performed on Day 1 (1, 2, 4, 6, and 24 hours post-dose
administration), and at Day 15 (pre-dose and 1, 2, 4, 6, and 24 hours post-dose
administration). For 24-hour timepoints, subjects return to the clinic on the following day

within 2 hours of the IP application time from the previous day for PK plasma sample
collection. A pre-dose/trough PK sample will be taken at Day 8.
Phase 2b (Cohort 2):
•
PK will be evaluated through trough/pre-dose sampling at Baseline, Day 29, and Day 85.
PK draws will be collected while the subject is having serum chemistries drawn at applicable
visits. The draws will be pre-dose investigational product application in the clinic. Ensure
investigational product is not applied in the area where PK will be drawn.
Medical Photography
Phase 2b (Cohort 2)
Photography will be performed at selected investigational sites using Canfield photography
equipment according to the Schedule of Visits and Assessment (Section 1.3) in Phase 2b
(Cohort 2). Photography will be optional. All efforts will be made to de-identify the subjects.
Sites participating in optional photography will obtain photos of nail with the worst dystrophy at
Baseline/Day 1 and at subsequent visits according to the Schedule of Visits and Assessments
(Section 1.3).
Final Study Visit – End of Study
Phase 1 (Cohort 1)
The approximate final study visit will occur at Week 3 (Day 22).
Phase 2b (Cohort 2):
The approximate final study visit will occur at Week 13 (Day 92).
For both Cohorts, the procedures performed during these visits are as described in the Schedule
of Visits and Assessments (Section 1.3). A 3-day scheduling window is allowed for this visit.
Adverse events will be recorded as reported by the subject and followed to resolution
(as necessary).
Early Termination Visit
If a subject is withdrawn or wishes to exit the study prior to the final study visit, an early
termination visit will be scheduled. This visit should include the procedures and assessments that
would be performed at the final study visit for either Cohort 1 or Cohort 2 (Section 1.3).
Unscheduled Visit
Unscheduled visits may be necessary to repeat testing following abnormal laboratory results, for
follow-up of AEs, or for any other reason, as warranted in the judgement of the Investigator.

Adverse Events
Adverse Event Definition
An AE means any untoward medical occurrence associated with the use of a drug in humans,
whether or not considered drug related. An AE can therefore be any unfavorable and unintended
sign (including an abnormal laboratory finding), symptom, or disease temporally associated with
the use of a medicinal (investigational) product, whether or not related to the medicinal
(investigational) product.
AEs will be collected following informed consent of the subject through subject study
completion.
A treatment emergent adverse event (TEAE) is defined as an AE that started post application of
investigational product through study completion.
Application site reactions will be considered adverse events if they require intervention,
suspension or discontinuation of investigational product.
Serious Adverse Event Definition
The definitions and reporting requirements of Health Canada/the Food and Drug Administration
(FDA)/ Therapeutic Goods Administration (TGA)/ICH Guidelines for Clinical Safety Data
Management, Definitions and Standards for Expedited Reporting, Topic E2A will be adhered to.
If any AEs are serious, as defined by ICH Guidelines for Clinical Safety, required procedures
will be followed.
All SAEs will be reported to the Sponsor (or delegate) via fax or e-mail within 24 hours of
becoming aware of the event, whether or not the serious events are deemed IP-related.
All serious event reporting will adhere to ICH E6: Guideline for Good Clinical Practice and
ICH E2A: Clinical Safety Data Management: Definitions and Standards for Expedited
Reporting.: The ERB/IRB will be notified of the Alert Reports as per HC, FDA, ICH and the
IRB/ERB’s policies and procedures. Refer to the Safety Reporting Instructions for SAE
reporting.
An SAE is any AE that in the view of either the PI or Sponsor, results in any of the following
outcomes: Death, a life-threatening AE, inpatient hospitalization or prolongation of existing
hospitalization, a persistent or significant incapacity or substantial disruption of the ability to
conduct normal life functions, or a congenital anomaly/birth defect. Important medical events
that may not result in death, be life-threatening, or require hospitalization may be considered
serious when, based upon appropriate medical judgment, they may jeopardize the subject and


Protocol ARQ-252-205

may require medical or surgical intervention to prevent one of the outcomes listed in the above
definition. Examples of such medical events include allergic bronchospasm requiring intensive
treatment in an emergency room or at home, blood dyscrasias or convulsions that do not result in
inpatient hospitalization, or the development of drug dependency or drug abuse.
Life-threatening is defined as an AE that in the view of the PI or Sponsor, places the subject at
immediate risk of death. It does not include an AE that, had it occurred in a more severe form,
might have caused death.
Hospitalization does not include the following:
•
Rehabilitation facilities, hospice facilities or respite care (e.g., caregiver relief)
•
Nursing homes or skilled nursing facilities
•
Emergency room visits
•
Same day surgeries (as outpatient/same day/ambulatory procedures)
•
<24 hour admissions for observation or evaluation
Hospitalization or prolongation of hospitalization in the absence of a precipitating, clinical AE is
not in itself an SAE. Examples include:
•
Admission for treatment of a preexisting condition that did not worsen
•
Hospitalizations for cosmetic elective surgery, social, and/or convenience admissions
•
Pre-planned treatments or surgical procedures should be noted in the history
documentation for the individual subject.
•
Diagnostic and therapeutic procedures, such as surgery, should not be reported as AEs;
however, the medical condition for which the procedure was performed should be
reported if it occurs during the reporting period and meets the definition of an AE. For
example, an acute appendicitis that begins during the AE reporting period should be
reported as an AE, and the resulting appendectomy should be recorded as treatment of the
AE.
Unexpected is defined as an AE that is not listed in the IB or is not listed at the specificity or
severity that has been observed; or is not consistent with the risk information described in the
general investigational plan or elsewhere in the current study documentation.
If a SAE occurs to a subject on this study, contact the Medical Monitor within one business day
of knowledge of event.
Suspected Unexpected Serious Adverse Reaction (SUSAR)
This is defined as a serious adverse reaction, the nature or severity of which is not consistent
with the known study treatment information. A serious event or reaction is not defined as a
SUSAR when: ‘it is serious but expected’ or it does not fit the definition of an SAE, whether
expected or not.

Safety Review with Subject
At each follow-up visit, subjects will be queried with an open-ended question such as:
‘How have you been feeling since your last visit?’ Additionally, the study staff will review
subject diaries and, if it appears that a potential AE was recorded, study staff will query the
subject and determine if an AE occurred.
AEs (whether serious or non-serious) and clinically significant abnormal laboratory test value(s)
will be evaluated by the PI and treated and/or followed up for up to one month after end of
treatment until the symptoms or value(s) return to normal, or acceptable levels, as judged by the
PI.
Where appropriate, medical test(s) and/or examination(s) will be performed to document
resolution of event(s). Outcome may be classified as resolved, improved, unchanged, worse, fatal
or unknown (lost to follow-up).
Adverse Event Reporting
AEs will be collected following informed consent of the subject through subject study
completion.
The Investigator will review each event and assess its relationship to investigational product
treatment (unrelated, unlikely, possibly, probably, likely). Each sign or symptom reported will be
graded on the NIH NCI CTCAE (Version 5.0) toxicity grading scale 5-point severity scale
(Grade 1, 2, 3, 4 and 5). The date and time of onset, time relationship to drug dosing, duration,
and outcome (resolved, improved, unchanged, worse, fatal, or unknown/lost to follow-up) of
each event will be noted.
The relationship of each AE to the investigational product will be assessed using the following
definitions:
Unrelated
•
The AE must clearly be caused by the subject’s clinical state, or the study
procedure/conditions.
•
Definitely not related to drug.
•
Temporal sequence of AE onset relative to administration of drug not reasonable.
•
Another obvious cause of an AE.
Unlikely
•
Time sequence is unreasonable.
•
There is another more likely cause for an AE.
Possibly
•
Corresponds to what is known about the drug.
•
Time sequence is reasonable.
•
Could have been due to another equally, likely cause.
Probably
•
Is a known effect of the drug.
•
Time sequence from taking drug is reasonable.
•
Ceases on stopping the drug.
•
Cannot be reasonably explained by the known characteristics of the subject’s clinical state.
Likely
•
Is a known effect of the drug (e.g., listed in Physicians' Desk Reference, Compendium of
Pharmaceuticals and Specialties, IB).
•
Time sequence from taking drug is reasonable.
•
Event stops upon stopping drug, event returns upon restarting drug.

The following CTCAE toxicity grading scale 5-point severity scale definitions for rating
maximum severity will be used:
Grade 1
Mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not
indicated.
Grade 2
Moderate; minimal, local or noninvasive intervention indicated; limiting age-appropriate
instrumental activities of daily living.*
Grade 3
Severe or medically significant but not immediately life-threatening; Hospitalization or
prolongation of hospitalization indicated; disabling; limiting self-care activities of daily living.**
Note: An experience may be severe but may not be serious, e.g., severe headache).
Grade 4
Life-threatening consequences; urgent intervention indicated.
Grade 5
Death related to AE.
Note: A semi-colon indicates ‘or’ within the description of the grade.
*Instrumental activities of daily living refer to preparing meals, shopping for groceries or clothes, using the
telephone, managing money, etc.
**Self-care activities of daily living refer to bathing, dressing and undressing, feeding self, using the toilet, taking
medications, and not bedridden.
AEs will be coded using the most current MedDRA® version available at the start of the study
(e.g., 21.0 or higher).
Reporting Pregnancy
During the study, all subjects should be instructed to contact the Investigator immediately if they
suspect they might be pregnant (e.g., missed or late menstrual period). If pregnancy is
confirmed, Investigational Product must be discontinued immediately, the subject should be
referred to an obstetrician experienced in reproductive toxicity for evaluation and counseling,
and the subject should be followed until conclusion of the pregnancy. Subject may be required to
sign a separate informed consent form to obtain pregnancy follow-up information, per local
requirements.
The Investigator is responsible for reporting all available pregnancy information on the
pregnancy report and submitting to the Medical Monitor within 24 hours of becoming aware of
the event, although pregnancy itself is not considered an AE. Follow-up information detailing
the outcome of the pregnancy and the health of the newborn should be reported as it becomes
available. Any pregnancy resulting in a congenital abnormality or birth defect of the newborn,
or neonatal death occurring within 30 days of the birth must be reported as a SAE, regardless of
causality. Any infant death that occurs after the 30 day reporting period that the Investigator
suspects is related to Investigational Product must also be reported as an SAE.
Partner pregnancies of a male subject will be reported.

DATA ANALYSIS
Data will be handled and processed according to the Contract Research Organization’s Standard
Operating Procedures, which are written based on the principles of GCP.
Statistical Methods
The methodology presented below is a summary of the more detailed analysis plan that will be
presented in the Statistical Analysis Plan (SAP). The SAP will be finalized before the database
is locked and unblinded. Any changes to the methods described in the final SAP will be
described and justified in the clinical study report.
All statistical processing will be performed using SAS® (Version 9.4) unless otherwise stated.
Descriptive statistics will be used to provide an overview of the safety, efficacy, and
pharmacokinetic results. For categorical parameters, the number and percentage of subjects in
each category will be presented. The denominator for percentage will be based on the number of
subjects appropriate for the purpose of analysis. For continuous parameters, descriptive statistics
will include n (number of subjects), mean, standard deviation (SD), median, minimum,
and maximum.
Missing efficacy data for IGA will be imputed using multiple imputation.
The primary statistical comparisons and secondary endpoints will be made at the
0.10 significance level and will not be adjusted for multiple comparisons.
Determination of Sample Size
Cohort 1 will include approximately 6 evaluable subjects, which is deemed adequate for the
purpose of evaluating safety and PK prior to Cohort 2.
There are approximately 215 subjects planned for Cohort 2. Approximately 61 subjects will
receive ARQ-252 cream 0.3% QD, approximately 61 subjects will receive ARQ-252 cream 0.3%
BID, approximately 31 subjects will receive ARQ-252 cream 0.1% QD, approximately 31
subjects will receive matching vehicle cream QD, and approximately 31 subjects will receive
vehicle cream BID. The randomization scheme will be 2:2:1:1:1 between these 5 treatment
groups, stratified by study site and IGA at Baseline.
The primary statistical comparisons will be to assess the ARQ-252 cream 0.3% group BID group
versus the vehicle BID group, to assess the ARQ-252 cream 0.3% QC group versus the vehicle
QD group, and to assess the ARQ-252 cream 0.1% QD group versus the vehicle QD group.
A sample size of 55 per active arm and 28 per vehicle arm will provide approximately 85%
power at the 2-sided 10% significance level to detect a difference in the rate of subjects attaining
an IGA score of clear or almost clear (for each ARQ-252-treated group versus vehicle group
within the same daily dosing frequency), assuming an active treatment response rate of 45% and
a vehicle response rate of 15%. This is based on a 2-group X2 test of equal proportions
(without continuity correction). With a 10% dropout rate, the sample size for the study would be
increased to 61 subjects per active arm and 31 subjects per vehicle arm (215 subjects total).

The primary statistical comparisons and evaluations of secondary endpoints will not be adjusted
for multiplicity.
Subjects to Analyze
Five analysis populations will be defined:
•
The Safety population will include all subjects who are enrolled and received at least one
confirmed dose of study medication. This population will be used for all safety analyses
and will be defined separately for each Cohort.
•
The Intent-to-Treat will include all subjects randomized to Cohort 2. This population
will be the primary analysis for the analysis of efficacy endpoints.
•
The Per-Protocol Population will include all subjects in the safety population, who were at
least 80% compliant with study medication application, and showed no important
deviations from the study protocol that would affect the interpretation of efficacy.
This population will be used as a sensitivity analysis of primary and secondary efficacy
endpoints.
•
The Pruritis population is a subset of the ITT population and include subjects with
WI‑NRS score ≥4 at Baseline. This population will be used for the analysis of WI-NRS.
•
The PK population will include all subjects receiving the active drug with sufficient
plasma concentrations of SHR0302 to define a profile, as determined by the
pharmacokineticist.
Interim Analysis
No interim efficacy analyses are planned. Safety data will be reviewed on an ongoing basis.
Background and Demographic Characteristics
Demographics, baseline disease characteristics, baseline height, weight, and BSA will be
summarized descriptively for all enrolled (Cohort 1) and randomized (Cohort 2) subjects.
Study Disposition
The number of subjects randomized, receiving IP, completing study, and withdrawing
prematurely (with reason for withdrawal) will be summarized by cohort and treatment group.
Protocol Deviations and Eligibility Deviations
The number of subjects with important protocol deviations and/or eligibility deviations will be
summarized by category and by treatment group.

Investigational Product Compliance
The number of IP applications by each subject based on diary data will be summarized using
descriptive statistics. The amount of IP used by each subject based on product weight will be
summarized by treatment using summary statistics (mean, SD, median, minimum, and
maximum), and categorically. IP compliance will be calculated based on number of applications
divided by the expected number (amount) of IP for each subject. Compliance will be
summarized descriptively by cohort and treatment group.
Efficacy Evaluation
Primary Efficacy Endpoint
The primary efficacy endpoint is the rate of subjects achieving an IGA score of ‘clear’ or ‘almost
clear’ at Week 12.
The primary statistical comparisons will be to assess the ARQ-252 cream 0.3% group BID group
versus the vehicle BID group, to assess the ARQ-252 cream 0.3% QD group versus the vehicle
QD group, and to assess the ARQ-252 cream 0.1% QD group versus the vehicle QD group.
The primary endpoint will be analyzed using a Cochran-Mantel-Haenszel test stratified by IGA
at Baseline and study site. Statistical significance will be concluded at the 2-sided 10%
significance level for each of the primary comparisons. Missing scores will be imputed using
multiple imputation.
Secondary Endpoints
The Secondary Efficacy Endpoints will include:
•
The rate of achievement of IGA of ‘clear’ or ‘almost clear’ PLUS at least a 2-point
improvement from Baseline at Weeks 2, 4, 8 and 12
•
The rate of achievement of at least a 2-point improvement from baseline at Weeks 2, 4, 8

The binary secondary endpoints will be analyzed using a Cochran-Mantel-Haenszel test stratified
by Baseline IGA and study site as with the primary endpoint. The continuous secondary
endpoints will be analyzed using an analysis of covariance stratified by Baseline IGA and study
site and Baseline values of the endpoint as independent variables. Statistical comparison
between the active treatment arm and vehicle arm will be facilitated by using contrasts.
Analyses may also include pooling the active treatment groups together for comparison against
the vehicle treatment groups; specifications for these analyses will be included in the SAP.
Safety Analysis
Descriptive statistics will be calculated for safety data and presented by visit and treatment group
for quantitative safety data and frequency counts will be compiled for classification of qualitative
safety data. Summaries of local tolerability will be presented by visit and treatment group.
Adverse Events
All treatment-emergent AEs occurring during the study will be recorded and classified on the
basis of MedDRA terminology for the safety population. Treatment-emergent AEs are those AEs
with an onset on or after the date of study treatment. All treatment-emergent AEs will be
summarized by treatment group, the number of subjects reporting treatment-emergent AEs,
system organ class, preferred term, severity, relationship, and seriousness. Serious adverse events
(SAEs) will be listed by subject. SAEs will be summarized by treatment group, severity, and
relationship to study treatment. For AEs, each subject will be counted only once within a system
organ class or a preferred term using the event with the greatest relationship and greatest
severity.
All information pertaining to AEs noted during the study will be listed by subject, detailing the
verbatim description given by the Investigator, preferred term, system organ class, start date,
stop date, severity, action taken regarding IP, corrective treatment, outcome, and IP relatedness.
The event onset will also be shown relative (in number of days) to date of first application.

Helsinki, and the ICH harmonized tripartite guideline regarding GCP (E6 (R2), Nov 2016) and
the applicable regulations of the country(ies) in which the trial is conducted.
Subject Information and Consent
The purpose of the study, the procedures to be carried out and the potential hazards will be
described to the subjects in non-technical terms. Subjects will be required to read, sign and date a
current version of the IRB/EC approved ICF summarizing the discussion prior to enrollment and
will be assured that they may withdraw from the study at any time without jeopardizing their
medical care.
Subjects will be given a signed copy of their ICF.
Study Completion and Termination
Study Completion
The study is considered completed with the last visit of the last subject participating in the study.
The final data from the investigational site will be sent to the Sponsor (or designee) after
completion of the final subject visit at that site, in the time frame specified in the Clinical Trial
Agreement.
Study Termination
The Sponsor reserves the right to close the investigational site or terminate the study at any time
for any reason at the sole discretion of the Sponsor. Investigational sites will be closed upon
study completion. An investigational site is considered closed when all required documents and
study supplies have been collected and a site closure visit has been performed. The Investigator
may initiate site closure at any time, provided there is reasonable cause and sufficient notice is
given in advance of the intended termination.

Reasons for the early closure of an investigational site by the Sponsor or Investigator may
include but are not limited to:
•
Failure of the Investigator to comply with the protocol, the Sponsor’s procedures, or GCP
guidelines.
•
Inadequate recruitment of subjects by the Investigator.
•
Discontinuation of further IP development
Study Monitoring
Prior to the initiation of the clinical investigation, Sponsor representatives or designees will visit
the clinical site where the investigation is to be conducted. Sponsor representatives shall ensure
that the Investigator understands the investigational status of the investigational product, all
requirements of the investigation to be undertaken, and all of his/her responsibilities as an
Investigator. Sponsor representatives will also visit the clinical site at appropriate intervals as
required to ensure compliance with the protocol and to verify the accuracy and completeness of
data reported on the CRFs. The Study Director or designees shall be available for consultation
with the Investigator and serve as liaisons between the clinical site and the Sponsor.
The Sponsor or authorized designees may inspect all documents and records required to be
maintained by the Investigator, including but not limited to medical records (office, clinic, or
hospital) and investigational product dispensation logs for the subjects in this clinical
investigation. The Investigator must permit access to such records. The Investigator must
obtain, as part of informed consent, permission for an authorized representative of the Sponsor,
or regulatory authorities, to review, in confidence, any records identifying subjects.
Data Quality Assurance
In order to ensure the collection of accurate, consistent, complete, and reliable data during this
clinical study, Sponsor representatives or designees may conduct audits of participating clinical
study sites at appropriate intervals throughout the study. The results of these periodic clinical
study site audits may be subject to review by independent auditors at completion of the clinical
investigation.
The Clinical Study Report will undergo QC review by the Clinical Research Organization’s
Quality Assurance (QA) department.
All clinical data will undergo a quality control check prior to clinical database lock. Edit checks
are performed for appropriate databases as a validation routine to check for missing data,
data inconsistencies, data ranges etc. Corrections are made prior to database lock.
Data Handling and Record Keeping
During the clinical study, the Investigator will maintain adequate records, including medical
records, records detailing the progress of the study for each subject, laboratory reports, signed
informed consent forms, investigational product disposition records, correspondence with the


Protocol ARQ-252-205

ERB/IRB and Study Monitor/Sponsor, AE reports, and information regarding subject
discontinuation and completion of the clinical investigation.
All required study data will be recorded on CRFs. Any change of data will be recorded on the
audit trail and a reason for the change will be entered.
The Principal Investigator must retain all documentation relating to the study for a period of at
least 2 years after the last marketing application approval or, if not approved, 2 years following
the discontinuance of the test article for investigation. If this requirement differs from any local
regulations, the local regulations will take precedence unless the local retention policy is less
than 2 years.
Protocol Amendments and Deviations
No change or amendment to this protocol may be made by the Investigator or Sponsor after the
protocol has been agreed to and signed by all parties unless such change(s) or amendment(s) has
(have) been agreed upon by the Investigator and Sponsor. Any change agreed upon will be
recorded in writing, and the written amendment will be signed by the Investigator and Sponsor.
Institutional review board approval is required prior to the implementation of an amendment,
unless overriding safety reasons warrant immediate action, in which case the IRB(s) will be
promptly notified.
No deviation from the protocol will be made except to protect the life or physical well-being of a
subject in an emergency. Except in such emergencies, prior approval of the Sponsor, and the
IRB, is required before deviations from the planned protocol. All protocol deviations that occur
during the study will be documented and reported to Sponsor and to the IRB(s), if applicable,
according to regulations. Further details about the documentation, evaluation, and follow-up of
protocol deviations are detailed in this study’s clinical monitoring plan.
No waivers to inclusion/exclusion criteria will be granted; subjects need to meet all criteria,
exactly as specified, to be enrolled. Additionally, prospective deviations from the protocol or
investigational plan are not permitted except to protect the life or physical well-being of a subject
in an emergency. Deviations that occur unintentionally or are the result of action by the subject
must be documented and reported to the IRB(s), if applicable, according to regulations. Further
details about the documentation, evaluation, and follow-up of protocol deviations are detailed in
this study’s clinical monitoring plan.
Confidentiality and Privacy
The Investigator must assure that subjects’ anonymity will be strictly maintained and that their
identities are protected from unauthorized parties. Only an identification code and any other
unique identifier(s) as allowed by local law (such as date of birth) will be recorded on any form
or biological sample submitted to the Sponsor.

OVERVIEW
This statistical analysis plan (SAP) describes the planned analysis and reporting for
Arcutis Biotherapeutics, Inc. protocol number ARQ-252-205 (A Phase 1/2b, Multiple Dose and
12-Week, Parallel Group, Double Blind, Dose Ranging, Vehicle-Controlled Study of the
Safety and Efficacy of ARQ-252 Cream 0.1% and ARQ-252 Cream 0.3% in Subjects with
Chronic Hand Eczema), dated 30-June-2020 Amendment Version 2. Reference materials for this
statistical plan include the protocol and the accompanying sample data collection documents.
Operational aspects related to collection and timing of planned clinical assessments are not
repeated in this SAP unless relevant to the planned analysis.
The structure and content of this SAP provides sufficient detail to meet the requirements
identified by the Food and Drug Administration (FDA), European Medicines Agency (EMA),
and International Conference on Harmonization (ICH) of Technical Requirements for
Registration of Pharmaceuticals for Human Use: Guidance on Statistical Principles in Clinical
Trials (ICH 1998). All work planned and reported for this SAP will follow internationally
accepted guidelines, published by the American Statistical Association (ASA 2018) and the
Royal Statistical Society (RSS 2014), for statistical practice.
The planned analyses identified in this SAP may be included in clinical study reports (CSRs),
regulatory submissions, or future manuscripts. Also, post-hoc exploratory analyses not

STUDY OBJECTIVES AND ENDPOINTS
2.1.
Study Objectives
2.1.1. Primary Objectives
The objectives of this study are as follows:
Phase 1 (Cohort 1):
•
To assess the safety, tolerability, and pharmacokinetics (PK) of once daily (QD)
application of ARQ-252 0.3% to both hands for 2 weeks in 6 subjects with chronic hand
eczema

Phase 2b (Cohort 2):
•
To assess the safety and efficacy of ARQ-252 cream 0.1% QD and ARQ-252 cream 0.3%
QD and twice daily (BID), vs vehicle applied QD and BID for 12 weeks to subjects with
chronic hand eczema
2.2.
Study Endpoints
2.2.1. Efficacy Endpoints
2.2.1.1.
Primary Efficacy Endpoint
Phase 1 (Cohort 1):
Not applicable.
Phase 2b (Cohort 2):
The primary endpoint of Cohort 2 is:
•
The rate of an Investigator Global Assessment (IGA) score of “clear” or “almost clear” at
Week 12
The primary estimand for the primary efficacy endpoint of this study is the odds of achieving
IGA score of “clear” or “almost clear” (i.e., IGA success) at 12 weeks; that is, the ratio of the
odds of achieving IGA success at 12 weeks ARQ-252 relative to the odds of success at 12 weeks
of using a matching vehicle cream. In the course of the 12-week randomized treatment period,
subjects may be exposed to possible known or unknown intercurrent events that could possibly
affect the estimand, such as treatment discontinuation due to a specific adverse effect or perhaps
a lack of effect. The “Treatment Policy Strategy” has been adopted for handling all known or
unknown intercurrent events in this study. To this end, the ITT principle will serve as the
analytical basis for interpreting the estimand. In other words, the odds ratio of achieving IGA
success for ARQ-252 relative to vehicle at 12 weeks will be evaluated regardless of the
occurrence of any such intercurrent event. This estimand shall be estimated using the
Cochran-Mantel-Haenszel (CMH) approach and applies to the following treatment comparisons:
•
ARQ-252 cream 0.3% BID versus vehicle cream (all dose frequencies)
•
ARQ-252 cream 0.3% QD versus vehicle cream (all dose frequencies)
•
ARQ-252 cream 0.1% QD versus vehicle cream (all dose frequencies)
•
ARQ-252 cream (all strengths and dose frequencies) versus vehicle cream (all dose
frequencies)
•
ARQ-252 cream 0.3% (all dose frequencies) versus vehicle cream (all dose frequencies)

OVERALL STUDY DESIGN AND PLAN
3.1.
Overall Design
This is a phase 1/2b, multiple dose and 12-week, parallel group, double blind, dose ranging,
vehicle-controlled study of the safety and efficacy of ARQ-252 cream 0.1% and ARQ-252 cream
0.3% in subjects with chronic hand eczema.
There are 2 cohorts of subjects:
•
Cohort 1 is a multiple dose cohort in which subjects with chronic hand eczema will be
assigned to ARQ-252 cream 0.3% QD x 2 weeks to be applied to both hands.
Pharmacokinetics and tolerability will be evaluated.
•
Cohort 2 is a parallel group, double blind, vehicle-controlled cohort in which subjects
with chronic hand eczema will be randomized to ARQ-252 cream 0.3% QD, ARQ-252
cream 0.3% BID, ARQ-252 cream 0.1% QD, vehicle cream BID, or vehicle cream
QD x 12 weeks to be applied to both hands. Safety and efficacy will be evaluated.
A total of approximately 6 evaluable subjects will be enrolled in Cohort 1, and a total of
approximately 215 subjects will be enrolled in Cohort 2. After having met all inclusion criteria,
and none of the exclusion criteria, subjects in Cohort 1 will be assigned treatment with ARQ-252
cream 0.3% QD at the Baseline visit; and subjects in Cohort 2 will be randomized in a 2:2:1:1:1
ratio (ARQ-252 0.3% QD, ARQ-252 0.3% BID, ARQ-252 0.1% QD, vehicle cream QD, or
vehicle cream BID, respectively) and stratified by study site and IGA at baseline according to a
computer-generated randomization list.

For subjects enrolled in Cohort 1, subject participation involves a minimum of 7 clinic visits
including Screening, Baseline/Day 1, Day 2, Day 8, Day 15, Day 16, and Day 22. Subjects will
be treated with investigational product (ARQ-252 cream 0.3% QD) for 2 weeks. The interval
between the Screening and Baseline visits could be up to 4 weeks, therefore the anticipated
maximum duration of subject participation is 7 weeks.
For subjects enrolled in Cohort 2, subject participation involves a minimum of 7 clinic visits
including Screening, Baseline/Day 1, Week 2, Week 4, Week 8, Week 12, and Week 13.
Subjects will be randomized to a treatment group and will be treated with investigational product
for 12 weeks. The interval between the Screening and Baseline visits could be up to 4 weeks,
therefore the anticipated maximum duration of subject participation is 17 weeks.
3.2.
Sample Size and Power
Cohort 1 will include approximately 6 evaluable subjects, which is deemed adequate for the
purpose of evaluating safety and PK before Cohort 2 commences.
There are approximately 215 subjects planned for Cohort 2. The primary statistical comparisons
will be to assess the ARQ-252 cream 0.3% BID group versus the vehicle BID group, to assess
the ARQ-252 cream 0.3% QD group versus the vehicle QD group, and to assess the ARQ-252
cream 0.1% QD group versus the vehicle QD group. A sample size of 55 per active arm and
28 per vehicle arm will provide approximately 85% power at the 2-sided 10% significance level
to detect a difference in the rate of subjects attaining an IGA score of clear or almost clear
(for each ARQ-252-treated group versus vehicle group within the same daily dosing frequency),
assuming an active treatment response rate of 45% and a vehicle response rate of 15%. For
testing each active arm of 55 subjects versus the combined vehicle arms of 56 subjects, this
sample size provides over 90% power for the comparison of the rate of subjects attaining an IGA
score of clear or almost clear. This is based on a 2-group X2 test of equal proportions (without
continuity correction).
3.3.
Study Population
Subjects will be adults (≥18 years of age) males or females with chronic hand eczema involving
at least 0.3% BSA, with a minimum IGA of at least “Mild” (2) at baseline.
3.4.
Treatments Administered
Cohort 1 will include approximately 6 evaluable subjects; all subjects are to receive ARQ-252
cream 0.3% QD.
Approximately 61 subjects will receive ARQ-252 cream 0.3% QD, approximately 61 subjects
will receive ARQ-252 cream 0.3% BID, approximately 31 subjects will receive ARQ-252 cream
0.1% QD, approximately 31 subjects will receive matching vehicle cream QD, and
approximately 31 subjects will receive vehicle cream BID. The randomization scheme will be
2:2:1:1:1 between these 5 treatment groups, stratified by study site and IGA at Baseline.

Method of Assigning Subjects to Treatment Groups
Phase 1 (Cohort 1)
Phase 1 (Cohort 1) is open label and all enrolled subjects will be assigned treatment with
ARQ‑252 cream 0.3% QD at the Baseline visit. Subjects will be enrolled at the Baseline visit
after the Investigator confirms that the subject meets all eligibility criteria listed in the protocol.
Enrollment will be documented by the completion of the Enrollment Notification Form.
Phase 2b (Cohort 2)
Phase 2b (Cohort 2) is randomized. Randomization will take place at the Baseline visit after the
Investigator confirms that the subject meets all eligibility criteria listed in the protocol. Subjects
will be randomly assigned to apply ARQ-252 0.3% QD, ARQ-252 0.3% BID, ARQ-252
0.1% QD, vehicle cream QD, or vehicle cream BID by an interactive response technology
system (IRT).
Assignment of treatment arm will be made at a 2:2:1:1:1 ratio and stratified by study site and
IGA at baseline according to a computer-generated randomization list. Kits containing tubes of
investigational product will be assigned to each subject by the IRT system. A subject may
receive more than one kit for the treatment period. The kits and tubes will be labeled with a
unique number, in a blinded manner.
3.6.
Blinding and Unblinding
Phase 1 (Cohort 1) is not blinded.
Phase 2b (Cohort 2) is double-blinded, therefore neither the subjects nor the Investigator and
clinical personnel will be aware of which investigational product (ARQ-252 0.1% cream,
ARQ‑252 0.3% cream, or vehicle cream) an individual subject receives. The subjects,
Investigator, and clinical personnel will be aware of whether study is to be applied once daily or
twice daily.
In the event of a medical emergency where breaking the blind is required to provide medical care
to the subject, the Investigator may obtain the treatment assignment directly from the IRT system
for that subject. Refer to the current version of the IRT plan for details on unblinding. Treatment
assignments should, however, remain blinded unless assignment knowledge is necessary to
determine subject emergency medical care. The rationale for unblinding must be clearly
explained in source documentation and on the CRF, along with the date on which the treatment
assignment was obtained. The Investigator is requested to contact the Sponsor promptly in the
event of any treatment unblinding.
Blinding of study treatment is critical to the integrity of this clinical trial and therefore, if a
subject’s treatment assignment is disclosed to the Investigator, the subject will have the study
treatment discontinued. All subjects will be followed until study completion unless consent to do
so is specifically withdrawn by the subject.

Footnotes from table above:
a
Limited physical examination: skin, lungs, and heart only.
b
All samples listed to be collected at Visits 1, 2, 4, 5, and 7. If Baseline visit occurs within 14 days of Screening,
the Screening lab results may be utilized.
c
Height to be measured only at Visit 2 (Day 1). Weight will be collected at Baseline, Visits 4, 5 and 7.
d
Local tolerability assessments to be recorded prior to IP application for the Investigator assessment of skin
irritation (Berger and Bowman skin irritation score) and 10-15 minutes post IP application for the subject’s ‘0-3’
burning/stinging assessment. Note for investigator tolerability assessments: reactions at the site of IP
application, which may occur post-Baseline, should be differentiated from the preexisting inflammation
associated with the subject’s chronic hand eczema.
e
BSA will be measured as the affected BSA for each side of each hand. Affected areas of the lateral aspects of the
fingers and hands should be assigned to the palmar surface. IGA will be a 5-point scale ranging from clear
(0) to severe (4). IGA should be completed prior to other physician assessments and by the same Evaluator
at each study visit. HECSI is an instrument used in clinical trials to rate the severity of 6 clinical signs of hand
eczema and the extent of the lesions on each of 5 distinct hand anatomic areas by use of standard scales. The total
HECSI score is based on a 4-point clinical sign severity scale ranging from 0 (none/absent) to 3 (severe) and a
5-point scale rating the different affected hand anatomic area(s) ranging from 0 (0% affected area) to 4
(76% to 100% affected area).
f
Subjects will complete the WI-NRS pruritus assessment and NRS Pain assessment in the clinic during screening
and then daily at home from the Baseline/Day 1 visit through the Day 15 visit.
g
A serum pregnancy test will be administered to all females of child-bearing potential at Screening. A urine
pregnancy test will be administered at Visits 2, 4, 5, and 7 to all females of childbearing potential. A negative
result is required for continued participation in the study, and results must be available prior to dispensing of
investigational product.
h
FSH will be performed (if indicated) at Screening to confirm post-menopausal status.
i
On the first day of dosing (Day 1), PK samples will be collected at 1, 2, 4, 6 (all +/- 10 mins) and 24 hours
post-dose administration (Day 2, +/- 2 hours). On Day 15 (last dose application), PK samples will be collected
pre-dose, 1, 2, 4, 6, (all +/- 10 mins) and 24 hours post dose administration (Day 16, +/- 2 hours). For 24-hour
time points, subjects return to the clinic on the following day within 2 hours of the IP application time from the
previous day for pre-dose PK plasma sample. A pre-dose PK sample will be taken at Day 8.
j
Clinic personnel will apply assigned IP on Visits 2, 4 and 5 (Baseline, Day 8 and Day 15). Every tube should be
weighed before and after IP application and weights recorded. For the 24-hour PK sampling time point the
application of investigational product should occur after the PK sample has been collected.
k
Subject should return with investigational product kit at each Visit. Every tube should be weighed before and after
use and weights recorded when dispensed and returned.
l
Any emergent AEs will be followed in the clinic for up to 1 month at the Investigator’s discretion until resolved or
otherwise judged as clinically stable

STATISTICAL ANALYSIS AND REPORTING
4.1.
Introduction
Data processing, tabulation of descriptive statistics, calculation of inferential statistics, and
graphical representations will primarily use SAS (release 9.4 or higher). If the use of other
software is warranted, the final statistical methodology report will detail what software was used
for what purposes.
Continuous (quantitative) variable summaries will include the number of subjects (n) with
non-missing values, mean, standard deviation (SD), median, minimum, and maximum.
Categorical (qualitative) variable summaries will include the frequency and percentage of
subjects who are in the particular category or each possible value. In general, the denominator
for the percentage calculation will be based upon the total number of subjects in the study
population for each treatment group, unless otherwise specified.
The minimum and maximum will be reported with the same degree of precision (i.e., the same
number of decimal places) as the observed data. Measures of location (mean and median) will be
reported to 1 degree of precision more than the observed data and measures of spread
(SD, standard error [SE]) will be reported to 2 degrees of precision more than the observed data.
Percentages will be presented to 1 decimal place, unless otherwise specified.
Unless otherwise indicated, all statistical tests will be conducted at the 0.1 significance level
using 2-tailed tests, and P values will be reported. For the purposes of statistical comparisons, the
vehicle BID and vehicle QD groups will be pooled together. Testing will be performed for:
•
ARQ-252 cream 0.3% QD versus vehicle cream (all dose frequencies)
•
ARQ-252 cream 0.3% BID versus vehicle cream (all dose frequencies)
•
ARQ-252 cream 0.1% QD versus vehicle cream (all dose frequencies)
•
ARQ-252 cream (all strengths and dose frequencies) versus vehicle cream (all dose
frequencies)
•
ARQ-252 cream 0.3% (all dose frequencies) versus vehicle cream (all dose frequencies)
Corresponding 90% and 95% confidence intervals (CIs) will be presented for statistical tests.
Testing will be performed for the primary endpoint of IGA clear or almost clear, for change from
baseline in the HECSI score, and for the percent change from baseline in the HECSI score;
however, P values will be provided for informational purposes for other endpoints as specified in
Section 8. The primary statistical comparisons and evaluations of secondary endpoints will not
be adjusted for multiplicity.

The following analysis populations are planned for this study:
•
Safety Population (SAF): The Safety population will include all subjects who are
enrolled (Cohort 1) or randomized (Cohort 2) and received at least 1 confirmed dose of
investigational product (IP). This population will be used for all safety analyses and will
be defined separately for each cohort.
•
All Treated Population (ALLTRT): The All Treated population will include all
subjects in the Safety population in Cohort 1. This population will be the primary
analysis population for the analysis of Cohort 1 efficacy endpoints.
•
Intent-To-Treat Population (ITT): The ITT population will include all subjects
randomized to Cohort 2. This population will be the primary analysis population for the
analysis of Cohort 2 efficacy endpoints.
•
Per Protocol Population (PP): The PP population will include all subjects in the Safety
population in Cohort 2, who were at least 80% compliant with study medication
application, and showed no important deviations from the study protocol that would
affect the interpretation of efficacy. This population will be used as a sensitivity analysis
of Cohort 2 primary and select secondary efficacy endpoints (i.e., IGA, WI-NRS, and
HECSI analyses).
•
Pruritus Population (PRU4): The PRU4 population is a subset of the All Treated
population (Cohort 1) and ITT population (Cohort 2) and includes subjects with WI-NRS

4-point reduction in WI-NRS score as compared to baseline for this subset of subjects.
•
Pain NRS Population (PNRS4): The PNRS4 population is a subset of the All Treated
population (Cohort 1) and ITT population (Cohort 2) and includes subjects with Pain
NRS score ≥4 at baseline. This population will be used for the analysis of achievement of
a 4-point reduction in Pain NRS score as compared to baseline for this subset of subjects.
•
Pain NRS Population (PNRS3): The PNRS3 population is a subset of the All Treated
population (Cohort 1) and ITT population (Cohort 2) and includes subjects with Pain
NRS score ≥3 at baseline. This population will be used for the analysis of achievement of
a 3-point reduction in Pain NRS score as compared to baseline for this subset of subjects.
•
Pain NRS Population (PNRS2): The PNRS2 population is a subset of the All Treated
population (Cohort 1) and ITT population (Cohort 2) and includes subjects with Pain
NRS score ≥2 at baseline. This population will be used for the analysis of achievement of
a 2-point reduction in Pain NRS score as compared to baseline for this subset of subjects.

GENERAL ISSUES FOR STATISTICAL ANALYSIS
6.1.
Statistical Definitions and Algorithms
6.1.1. Baseline
For assessments where time was recorded (e.g., ECG), the last observation recorded before the
first application of study drug will be used as the baseline observation for all calculations of
change from baseline. For assessments where time was not recorded (excluding WI-NRS and
Pain NRS), the last observation recorded on or before the day of first application of study drug
will be used as the baseline observation for all calculations of change from baseline. For
WI-NRS and Pain NRS, since diaries were completed daily at home from the Baseline/Day 1
visit until end of treatment, baseline is defined as the last observation recorded before the day of
first application of study drug.
For assessments that are collected both before and after application of study drug at the
Baseline/Day 1 visit, the last observation recorded before the first dose of study will be used as
the baseline observation. For assessments collected only after application of study drug, no
baseline will be defined (except for subject local tolerability; in this case, baseline is defined as
the first non-missing observation recorded after the first application of study drug). If the
tolerability assessments are not done as per protocol Section 5.1.7, those records will be
excluded from the analysis.
6.1.2. Adjustments for Covariates
Covariates for this study include pooled site group (see Section 6.1.6) and IGA severity at
baseline (mild, moderate, or severe). Subgroup analyses may be generated for the baseline
covariates.
6.1.3. Multiple Comparisons
No adjustments for multiple comparisons will be made for this study.

6.1.4. Handling of Dropouts or Missing Data
Any subject who prematurely withdraws from the study will have their last available data
assigned to an analysis window as described in Section 6.1.5.
For the primary efficacy endpoint of IGA score (Phase 2b/Cohort 2 only), the primary analysis
will impute missing values using a regression-based multiple imputation model. This is a three
step process.
1. The first step is to understand the pattern of missingness. In order to perform the multiple
imputation, a monotone missing pattern has to be achieved. For example, if there exist
values for baseline, Week 8, and Week 12 visits, but missing values for the Week 2 or
4 visits, the Markov-Chain Monte-Carlo (MCMC) method will be used to impute the
small amount of missing data that may be missing at the intermediate visits that is
required to make the missing data pattern monotone before applying the multiple
imputation algorithm. This method uses a non-informative Jeffreys prior to derive the
posterior mode from the expectation-maximization (EM) algorithm as the starting values
for the MCMC method. MCMC method will use seed of 74746759. The IGA score will
be treated as a continuous variable for this step. To avoid values that could not be
observed in practice, imputed values will be constrained to be integers in the range of
0 to 4.
a.
The table below will determine the number of datasets to be imputed in this step.
Determine the proportion of datapoints with non-monotone pattern across all
visits and subjects which could be derived as a percentage of number of
nonmonotone data points/total number of expected data points.
This can be determined as

> 2% to ≤5%

> 5%

2. Once the monotone pattern is achieved, the next step is to implement the imputation
algorithm. For this, the Predictive Mean Matching method (PMM) will be used. This
method is particularly helpful if the normality assumption is violated. For subjects with
complete data up to a particular visit, a PMM model will be fit that includes the outcome
at that visit as the dependent variable and as independent variables, IGA score outcomes
at previous visits, treatment group, and pooled site group using a seed of 88734121. This
process will be repeated 25 times, resulting in a total of 25 to 250 complete analysis

datasets, depending on the number of imputed monotone datasets that are required. The
seed or number of imputed datasets may be changed after unblinding in case of any issues
with the imputation process, and it will be documented in the CSR if any change is
required.
3. For each completed dataset, compute the necessary derived variables. The dichotomous
success rate (clear or almost clear) will be derived. The results obtained will be analyzed
using the CMH analysis for each of the complete analysis data sets stratified by baseline
IGA score and site. The results will be combined into one multiple imputation inference
(odds ratio, associated CI, and P value) using PROC MIANALYZE as illustrated below
(Ratitch 2013).
This approach to imputation should be superior to other strategies such as carrying forward the
last available observation, which may yield unrealistic imputed values. Also, the use of multiple
imputation avoids the problem of artificially increasing power through data imputation
associated with single-imputation methods because it accounts for the uncertainty associated
with the imputation. Other missing data will not be imputed, with the exception of incomplete
dates as described in Section 6.1.8. For responder analyses, missing data will be treated as a
nonresponse with the exception of IGA. Only observed data will be summarized using
descriptive statistics.
The SAS pseudo code for the multiple imputation process is listed below:
Step 1:
proc mi data=example seed=74746759 nimpute=XX round=1 out=example_1;
mcmc impute=monotone;
var <baseline score> ………… <visit12 score>;
run;
Step 2:
proc mi data=example_1 seed=88734121 nimpute=XX
out=example_2;
class <treatment> <site>;
monotone regpmm(<baseline score> ………… <visit12 score>);
var <treatment> <site> <baseline score> ………… <visit12 score>;
run;
XX will be the determined based on the proportion of missing data across visits.
Step 3: This step involves running CMH test stratified by baseline IGA score and site on each
completed dataset and combining the results using PROC MIANALYZE.
proc freq data=example noprint;
by <imputationnumber> <visit> ;
tables <site> * <BL IGA> * <treatment> * <outcome> / cmh alpha=0.1;
output out=example_stat cmh;

In order to apply PROC MIANALYZE, normalizing transformations have to be applied to odds
ratio. P values are obtained using Wilson Hilferty transformation as illustrated
(Ratitch 2013).
6.1.5. Analysis Visit Windows
6.1.5.1.
Non-Diary Assessments
Visits will be analyzed as scheduled (i.e., not subject to visit windowing). Unscheduled, early
termination, and/or repeated measurements will only be included if a scheduled measurement is
not available and the unscheduled, early termination, or repeated measurement falls within the
analysis visit windows as described in Table 3 (Cohort 1 [Phase 1]) and Table 4
(Cohort 2 [Phase 2b]). The windows follow the Schedule of Events in Table 1 and Table 2.
Visits falling outside of these windows will not be windowed (e.g., an unscheduled visit before
first application of study drug). Unscheduled/repeated measurements will be listed.

6.1.6. Pooling of Sites
Sites will be pooled for statistical analysis as follows. For analysis, sites should have a minimum
of 10 randomized subjects. The smallest sites will be grouped sequentially in order of smallest to
largest within each country, restricting to those sites that did not meet the minimum enrollment
of 10, until each pooled site has a minimum of 10 subjects within each country with at least
1 subject in each treatment group.
6.1.7. Derived Variables
•
Study Week = 7-day periods starting on Day 1, as described in Section 6.1.5.2. For
example, Study Week 1 corresponds to Days 1 to 7. This is in contrast to Study Visit,
which describes the actual clinic visit week. The nomenclature of “Study Week” will be
used with respect Pain NRS and WI-NRS analyses; otherwise, “Study Visit” will be used.
•
IGA Improvement = achievement of at least a 2-point improvement (i.e., reduction) in
IGA score from baseline.

otherwise, questions are scored such that never = 0, rarely = 1, sometimes = 2, often = 3,
and all the time = 4. The range for QOLHEQ Total score is 0 to 117, where lower scores
indicate better outcomes. If 1 to 3 questions have a missing result, set the missing result
to 0 before summing; if more than 3 questions are missing, then the QOLHEQ Total
score cannot be calculated.
•
Total Hand % BSA Affected by Disease = sum of % BSA affected by disease from the
following hand areas: left palmar, left dorsal, right palmar, and right dorsal. All 4 hand
areas must have a result for the total hand % BSA affected by disease to be calculated.
•
Compliance = number of applications divided by the expected number of investigational
product (IP) applications for each subject. Compliance will be calculated using drug
accountability data over the entire treatment period for each subject, up to treatment
completion or discontinuation.

6.1.8. Data Adjustments/Handling/Conventions
All collected data will be presented in listings. Data not subject to analysis according to this plan
will not appear in any tables or graphs but will be included only in the data listings.
All P values will be displayed in four decimals and rounded using standard scientific notation
(e.g., 0.XXXX). If a P value less than 0.0001 occurs it will be shown in tables as <0.0001;
similarly, if a P value greater than 0.9999 occurs it will be shown in tables as >0.9999.
Adverse events will be coded using the Medical Dictionary for Regulatory Activities (MedDRA)
version 23.0 thesaurus.
Medications will be coded using the World Health Organization Drug Dictionary Enhanced
(WHO-DDE) Global B3 version September 2019.
A treatment-related AE is any AE with a relationship to the study drug of possibly related,
probably related, likely related, or missing.
For partial AE and medication start dates:
•
If the year is unknown, then do not impute the date but assign a missing value.
•
If the year is known, but the month or month and day is unknown, then:
o If the year matches the year of first dose date and the end date (if present) is after first
dose date, then impute as the month and day of the first dose date.
o Otherwise, assign 01 January.

the day of the first dose date.
o Otherwise, assign 01.
For partial AE and medication end dates:
•
If the year is unknown, then do not impute the date but assign as missing value.
•
If the year is known, but the month or month and day is unknown, then:
o If the year matches the year of the last date of the study (date of last contact if subject
lost to follow-up; date of completion or early termination otherwise), then impute as
the month and day of the last date of the study.
o Otherwise, assign 31 December.
•
If the year and month are known, but the day is unknown, then:
o If the month and year match the month and year of the last date of the study, then
impute as the day of the last date of the study.
o Otherwise, assign the last day of the month.
These conventions will be applied to AE and medication onset dates and times with the
following precaution: if the missing date and time reflect the date and time of onset of an AE, the
modified date and time will be constructed to match the first documented date/time post drug
administration while preserving the order in which the AE was reported in the eCRF.
In cases where variables for questionnaires were derived in the eCRF (e.g., total scores) and a
derivation is indicated in Section 6.1.7, the results as derived by statistics (as opposed to the
results derived in the eCRF) will be used in analysis.
6.1.9. Presentation of Cohorts and Treatments in Summaries
Study subjects and demographic summaries will be presented by cohort and treatment in the
same output, as follows:

Special Handling for COVID-19 Disruptions
In some cases, study visits will have to be delayed/not performed as a result of COVID-19
disruptions (e.g., sites were closed or subjects were under stay-at-home orders). Where possible,
study sites may collect post-baseline data from subjects remotely by telephone, traditional mail,
and/or email; this will be clearly documented in the source. If possible, sites should adhere to the
protocol visit window for remote data collection.
Investigator assessments and subject questionnaires normally completed during on-site visits
should be completed on the appropriate paper source documents. The following
assessments/questionnaires are approved to be collected via telemedicine/remotely:
•
WI-NRS
•
Pain NRS
•
Subject Local Tolerability
•
QOLHEQ
•

Primary Efficacy Analysis
8.1.1. Investigator Global Assessment (IGA) Score of “Clear” or “Almost Clear” at
Week 12
The IGA is a static evaluation of qualitative overall chronic hand eczema severity. This global
assessment scale is an ordinal scale with five severity grades (reported only in integers of 0 to 4).
Each IGA Severity Score is defined by distinct and clinically relevant morphologic descriptions
that minimizes inter-observer variability. Table 7 illustrates the description of each severity
grade.

Categorical Data Analysis
The primary efficacy endpoint is the rate of subjects achieving an IGA score of “Clear” or
“Almost Clear” at Week 12.
The primary statistical comparisons for Cohort 2 subjects will be as follows:
•
ARQ-252 cream 0.3% BID versus vehicle cream (all dose frequencies)
•
ARQ-252 cream 0.3% QD versus vehicle cream (all dose frequencies)
•
ARQ-252 cream 0.1% QD versus vehicle cream (all dose frequencies)
•
ARQ-252 cream (all strengths and dose frequencies) versus vehicle cream (all dose
frequencies)
•
ARQ-252 cream 0.3% (all dose frequencies) versus vehicle cream (all dose frequencies)
The primary endpoint will be analyzed using a CMH test stratified by pooled study site group
and baseline IGA category. Statistical significance will be concluded at the 10% significance
level (2-sided) or less, as discussed in Section 4.1. Odds ratios and 90% and 95% CIs for the
odds ratios will be provided. Additionally, the 90% and 95% Wilson CIs for proportion of
successes in each treatment group will be presented.
For the primary analysis, missing IGA scores will be imputed using multiple imputation as
described in Section 6.1.4. These imputations will result in a minimum of 25 to a maximum of
250 complete analysis datasets, depending on the number of imputed monotone datasets
required. The CMH analyses will be performed separately for each of the complete analysis data
sets, and the results will be combined into one multiple imputation inference (estimated
treatment effect and associated CI and P value).
The primary efficacy analysis will be based on Cohort 2 subjects in the ITT population.
8.1.2. Sensitivity Analyses of the Primary Efficacy Endpoint
The following sensitivity analyses will be performed, based on the CMH test as described in
Section 8.1:
•
The primary efficacy endpoint analysis, repeated on Cohort 2 subjects in the ITT and
PP populations on nonimputed data; and
•
The primary efficacy endpoint analysis (excluding the CMH testing), repeated on
Cohort 1 subjects in the All Treated population on nonimputed data only.

8.2.3. Hand Eczema Severity Index (HECSI)
The secondary efficacy endpoints relating to HECSI are:
•
Change and percent change in HECSI score at Weeks 2, 4, 8, 12, and 13 compared to
Baseline
•
Achievement of HECSI-75
The HECSI is an instrument used in clinical trials to rate the severity of 6 clinical signs of hand
eczema and the extent of the lesions on each of 5 hand areas by use of standard scales. The total
HECSI score is based on a 4-point severity scale ranging from 0 (none/absent) to 3 (severe) and
a 5-point scale rating the affected area(s) ranging from 0 (0% affected area) to 4 (76% to 100%
affected area). Derivations for each of the subscores and the total score can be found in
Section 6.1.7.
Change and percent change from baseline to Weeks 2, 4, 8, 12, and 13 in HECSI subscores
(Fingertips, Fingers [except Tips], Palm of Hands, Back of Hands, and Wrists) and total score
will be analyzed using descriptive statistics and an ANCOVA with terms for treatment group,
pooled site group, baseline IGA category, and baseline HECSI score as covariates, by study visit.
Statistical comparisons between the treatment groups will be obtained using contrasts. The LS
means, standard errors, 90% and 95% CIs, and P values will be presented. This analysis will be
based on Cohort 2 subjects in the ITT population (nonimputed data only) and PP population
(ANCOVA using nonimputed data only). Additionally, this analysis will be repeated for Cohort
1 subjects in the All Treated population, excluding between-treatment contrasts (due to being a

Frequencies and percentages of subjects achieving HECSI-75 will be presented by study vist and
treatment group. This endpoint will be analyzed using CMH tests stratified by pooled site group
and baseline IGA category similar to the primary analysis in Section 8.1, with the exception that
missing data will not be replaced. Odds ratios and 90% and 95% CIs of the odds ratios will be

4, 5, 6, 7, 8, 9, 10, 11, 12, and 13 weeks after first application of study drug in subjects
with baseline Pain NRS score of at least 3
•
The rate of achievement of ≥2-point reduction from Baseline in Pain NRS score at 1, 2, 3,
4, 5, 6, 7, 8, 9, 10, 11, 12, and 13 weeks after first application of study drug in subjects
with baseline Pain NRS score of at least 2
The Pain NRS score is the subject’s assessment of worst pain intensity over the past 24 hours on
a scale of 0 to 10, where 0 = “no pain” and 10 = “worst possible pain”.
Change in Pain NRS Score Analysis
Change and percent from baseline to 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, and 13 weeks after first
application of study drug in average weekly Pain NRS score will be analyzed using descriptive
statistics and an ANCOVA with terms for treatment group, pooled site group, baseline IGA
category, and baseline Pain NRS score as covariates, by study visit. Statistical comparisons
between the treatment groups will be obtained using contrasts. The LS means, standard errors,
90% and 95% CIs, and P values will be presented. This analysis will be based on Cohort 2
subjects in the ITT population (nonimputed data only). Additionally, this analysis will be
repeated for Cohort 1 subjects in the All Treated population, excluding between-treatment
contrasts (due to being a single-treatment cohort).
Rate of Achievement Analysis
In subjects with a baseline Pain NRS score ≥4, achievement of a ≥4-point improvement from
baseline in average weekly Pain NRS score at 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, and 13 weeks
after first application of study drug will be analyzed using CMH tests stratified by pooled site
group and baseline IGA category similar to the primary analysis in Section 8.1, with the
exception that missing data will not be replaced. Odds ratios and 90% and 95% CIs of the odds
ratios will be provided. Additionally, the 90% and 95% Wilson CIs for proportion of successes
in each treatment group will be presented. This analysis will be based on Cohort 2 subjects in the
PNRS4 population (nonimputed data only). Additionally, this analysis will be repeated for
Cohort 1 subjects in the PNRS4 population, excluding the CMH test (due to being a single-
treatment cohort).
This analysis will furthermore be repeated on subjects with a baseline Pain NRS score ≥3 and a
baseline Pain NRS score ≥2 for achievement of a ≥3-point improvement from baseline and a
≥2-point improvement from baseline, respectively. This analysis will be performed on subjects in
the PNRS3 and PNRS2 populations, with each cohort presented separately (where the CMH
testing in Cohort 1 will be excluded).

8.2.5. Quality of Life in Hand Eczema Questionnaire (QOLHEQ)
The secondary efficacy endpoint relating to QOLHEQ is:
•
Change and percent change from baseline in overall QOLHEQ score at each study visit
The construct HRQOL includes all impairments or limiting conditions caused by the health state
of an individual. The QOLHEQ is a disease specific instrument, thereby only assessing
impairments caused by hand eczema. It consists of 30 items which can be summarized according
to four domains of HRQOL: Impairments because of (1) symptoms, (2) emotions, (3) limitations
in functioning, or (4) because of treatment and prevention. Derivations for each of the subscores
and the total score can be found in Section 6.1.7.
Change and percent change from baseline to Weeks 2, 4, 8, 12, and 13 in QOLHEQ subscores
(Symptoms, Emotions, Limitations in Function, Treatment and Prevention) and total score will
be analyzed using descriptive statistics and an ANCOVA with terms for treatment group, pooled
site group, baseline IGA category, and baseline overall QOLHEQ score as covariates, by study
visit. Statistical comparisons between the treatment groups will be obtained using contrasts. The
LS means, standard errors, 90% and 95% CIs, and P values will be presented. These analyses
will be based on Cohort 2 subjects in the ITT population (nonimputed data only).
8.2.6. Percent Body Surface Area (BSA) Affected by Disease
The secondary efficacy endpoint relating to percent BSA affected by disease (dorsal [left hand],
dorsal [right hand], palmar [left hand], palmar [right hand], total hand) is:
•
Percent BSA affected by disease and % change from baseline in BSA affected by disease
at baseline, 2 weeks, 4 weeks, 8 weeks, 12 weeks, and 13 weeks
Change and percent change from baseline to Weeks 2, 4, 8, 12, and 13 in percent BSA affected
by disease will be analyzed using descriptive statistics and an ANCOVA with terms for
treatment group, pooled site group, baseline IGA category, and baseline percent BSA affected by
disease as covariates, by study visit. Statistical comparisons between the treatment groups will be
obtained using contrasts. The LS means, standard errors, 90% and 95% CIs, and P values will be
presented. This analysis will be based on Cohort 2 subjects in the ITT population
(nonimputed data only). Additionally, this analysis will be repeated for Cohort 1 subjects in the

Exploratory Efficacy Analysis
The exploratory efficacy endpoint is:
•
Change from Baseline in Nail Dystrophy at each visit
In subjects with a nail dystrophy at baseline, change in number of millimeters of normal-
appearing nail distal to the cuticle will be summarized by treatment group and study visit. Since
the number if millimeters of normal-appearing nail distal to the cuticle at baseline was not
collected, it is assumed to be 0 mm; similarly, for subjects with nail dystrophy at baseline, if they
report having no normal-appearing nail distal to the cuticle after baseline, their result is imputed
as 0 mm (as this amount is not collected in the eCRF). This analysis will be based on Cohort 2
subjects in the ND population (nonimputed data only).
9.
SAFETY AND TOLERABILITY ANALYSIS
Safety will be evaluated from reported AEs, physical examinations, local tolerability
assessments, changes in clinical laboratory values, and changes in vital signs/weight. No
inferential statistical tests will be performed.
All safety analyses will be performed on the Safety population.
Presentation of treatments for safety analysis summary tables are described in Section 6.1.9.
9.1.
Adverse Events
All AEs, TEAEs, and SAEs will be coded using the MedDRA dictionary version 23.0.
A TEAE is defined as an AE within an onset on or after the day of study treatment through study
completion. An overall summary of TEAEs will be provided; this will present number and
percent of subjects who reported at least 1 of the following: TEAE (including all TEAEs, TEAEs
by maximum severity, and related TEAEs), SAE, discontinued the study due to a TEAE,
discontinued the study drug due to a TEAE, or a TEAE resulting in death.
The number and percent of subjects reporting TEAEs, grouped by MedDRA system organ class
(SOC) and preferred term, will be tabulated by severity or by greatest relationship to study drug
and treatment group within cohort. In the case of multiple occurrences of the same TEAE within
the same subject, each subject will only be counted once for each preferred term. Additionally,
the number and percent of subjects reporting related TEAEs will be summarized by MedDRA
SOC, preferred term, severity, and treatment group within cohort.
Relationship to study drug will be mapped as follows: related = likely related, probably related,
or possibly related; unrelated = unlikely related or unrelated. In the summaries showing severity
and relationship to study medication the event with the maximum severity (mild < moderate
< severe < life-threatening < death) or strongest relationship (unrelated < related) will be
reported. If a particular event is missing the severity and/or relationship, then the strongest
possible severity or relationship will be assumed for analysis (severity = severe,
relationship = related).

In the AE data listings, all AEs will be displayed. Any AEs that are treatment emergent will be
flagged.
9.1.1. Adverse Events Leading to Withdrawal
A summary of incidence rates (frequencies and percentages) of TEAEs leading to withdrawal of
study drug by treatment group within cohort, SOC, and preferred term will be prepared for the
Safety population. Additionally, this table will be repeated for related TEAEs leading to
withdrawal of study drug and all TEAEs leading to withdrawal from the study. No inferential
statistical tests will be performed.
A data listing of AEs leading to withdrawal of study drug will also be provided, displaying
details of the event(s) captured on the eCRF.
9.1.2. Deaths and Serious Adverse Events
Any deaths that occur during the study will be listed.
Serious adverse events (SAEs) will be listed and tabulated by SOC and preferred term and
presented by treatment group within cohort, by severity, and by relationship to study treatment.
9.2.
Local Tolerability Assessments
The investigator’s assessment of the application site reaction will be summarized by study visit
and treatment group within cohort using both categorical methods (number and percentage of
subjects with each score) as well as continuous methods (e.g., mean, median). Categorical
summaries will be provided for dermal response as well as other effects. No inferential statistical
tests will be performed.
The subject’s assessment of the application site reaction will be summarized similarly.
9.3.
Clinical Laboratory Evaluations
Laboratory test results will be summarized descriptively by treatment and study visit as both
observed values and change from baseline values for continuous hematology, chemistry
(including thyroid), and urinalysis results. Categorical urinalysis results will be summarized
using frequencies by study visit and treatment group within cohort.
The number of subjects with clinical laboratory values below, within, or above the normal range
by study visit and in relation to baseline will be tabulated for each clinical laboratory analyte by
treatment group within cohort (shift table).
Abnormal results will be flagged in the listings. In addition, pregnancy test results and hormonal
laboratory results will be listed.

Vital Signs
Descriptive summaries of observed values and changes from baseline will be calculated for
systolic blood pressure, diastolic blood pressure, heart rate, height, weight, BMI, and oral body
temperature by treatment group within cohort and study visit.
9.5.
12-Lead Electrocardiograms
Descriptive summaries for observed values and change from baseline will be presented for
12-lead electrocardiogram (ECG) measures of PR interval, QRS interval, QT interval, QTc
interval (Fridericia’s [QTcF] correction method), and heart rate. These summaries will be
presented by study visit and treatment group within cohort.
The number and percentage of subjects with each ECG investigator interpretation (normal;
abnormal, not clinically significant; or abnormal, clinically significant) will be displayed for each
treatment group within cohort and study visit.
9.6.
Physical Examination
The number and percentage of subjects with normal and abnormal findings in the physical
examination will be displayed at each study visit and treatment group within cohort.
9.7.
Concomitant Medications
Prior and concomitant medications will be summarized descriptively by treatment within cohort,
Anatomical Therapeutic Chemical (ATC) Class Level 4, and Preferred Term using counts and
percentages.
Prior medications will be presented separately from concomitant medications. Medications that
started before the first application of IP will be considered prior medications whether or not they
were stopped before the first application of study drug. Any medications continuing or starting
after the first application of study drug will be considered to be concomitant. If a medication
starts before the first application of study drug and continues after the first application of study
drug it will be considered both prior and concomitant.
9.8.
Modified Total Lesion Symptom Score (mTLSS)
The modified Total Lesion Symptom Score (mTLSS) is used to determine the intensity of
features as part of the IGA Severity Score. The total mTLSS is calculated as the sum of scores
(0 = absent, 1 = mild, 2 = moderate, 3 = severe) assigned by the investigator for the chronic hand
eczema parameters.
This endpoint was removed from the protocol as of amendment 1 (11May2020), thus a limited
number of subjects and visits had data collected. The mTLSS results will be listed only.

CHANGES FROM PLANNED ANALYSIS
The following analysis populations have been added:
•
The PRU4 population has been added to facilitate WI-NRS analysis on the ITT
population;
•
The PNRS4, PNRS3, and PNRS2 populations have been added to facilitate Pain NRS
analysis for subjects achieving a 4-point, 3-point, and 2-point reduction from baseline,
respectively; and
•
The All Treatment population has been added to facilitate Cohort 1 efficacy analyses.
•
The ND population has been added to facilitate Cohort 2 analyses of nail dystrophy.
These populations are not included in the protocol.
The exploratory endpoint is change from baseline in nail dystrophy; since no baseline
measurement will be collected for millimeters of normal nail distal to cuticle, it will be assumed
that the amount of normal nail at baseline is 0 mm.
The definition of compliance was updated to exclude subjects who missed more than
3 consecutive days of dosing, versus subjects who missed more than 3 consecutive doses.
The following secondary endpoints were added upon request by the Sponsor:
•
The rate of achievement of IGA of “clear” or “almost clear” PLUS at least a 2-point
improvement from Baseline at Week 13
•
The rate of achievement of at least a 2-point improvement from baseline at Week 13
•
The rate of achievement of IGA of “clear” or “almost clear” at Week 13
•
Change in IGA score at Week 13 as compared to baseline
•
Change in WI-NRS pruritus score at 1, 3, 5, 6, 7, 9, 10, 11, and 13 compared to baseline
(Weeks 2, 4, 8, and 12 were already included)
•
Percent change in WI-NRS pruritus score at 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, and

Sponsor, all efficacy data collected for Cohort 1 (IGA, HECSI, average weekly WI-NRS,
average weekly Pain NRS, and % BSA affected by disease) will be summarized.
Subgroup analyses for IGA Success by study site (Week 12 only) and by baseline IGA severity
were added.
An analysis of HECSI-75 and total % BSA affected by disease were also requested to be added.
All analyses of time to event (i.e., time to IGA of “clear” or “almost clear”; time to the first
achievement of ≥4-point reduction from Baseline in WI-NRS pruritus score in subjects with
Baseline WI-NRS pruritus score of at least 4; and time to the first achievement of ≥4-point
reduction from Baseline in Pain NRS score in subjects with Baseline Pain NRS score of at least

Planned Listing Descriptions
The following are planned data and patient/subject data listings for protocol number
ARQ-252-205.
In general, one listing will be produced per CRF domain. All listings will be sorted by treatment,
site, and subject number. All calculated variables will be included in the listings. Screen failures
will only be presented in Listing 16.2.2.1.
In all listings a blank line will be placed between each subject. Within a data listing, if an item
appears line after line (e.g., repetition of subject number), then only the first occurrence will be
displayed.
In data listings, the information for one subject will be kept on one page if at all possible, rather
than splitting a subject’s information across pages.

Note: Percentages are n/Number of subjects in the Safety Population within overall (Cohort 1) or treatment received (Cohort 2)*100.
[1] Only captured for female subjects; percentages are based on the number of female subjects in the Safety population.
[2] The WI-NRS was determined by asking the subject’s assessment of worst itch over the past 24 hours. The scale is from 0 to 10, which ranges from “no itch” to “worst imaginable itch”.
[3] Lower scores indicate better outcomes.
[4] The Pain NRS is the subject’s assessment of worst pain intensity over the past 24 hours. The scale is from 0 to 10, which ranges from “no pain” to “worst possible pain”.

Eczema Questionnaire; WI-NRS = Worst Itch – Numeric Rating Scale.
Note: Percentages are n/Number of subjects in the Safety population within overall (Cohort 1) or treatment received (Cohort 2)*100.
[1] Only captured for female subjects; percentages are based on the number of female subjects in the Safety population.
[2] The WI-NRS was determined by asking the subject’s assessment of worst itch over the past 24 hours. The scale is from 0 to 10, which ranges from “no itch” to “worst imaginable itch”.
[3] Lower scores indicate better outcomes.
[4] The Pain NRS is the subject’s assessment of worst pain intensity over the past 24 hours. The scale is from 0 to 10, which ranges from “no pain” to “worst possible pain”.

Abbreviations: ATC = Anatomic Therapeutic Chemical; BID = twice daily; PT = preferred term; QD = once daily; WHO-DDE = World Health Organization-Drug Dictionary Enhanced.
Note: Percentages are n/Number of subjects in the Safety population within treatment received*100. Medications were coded using WHO-DDE Global B3 version September 2019. Prior
medications are all medications that were started before the application of study drug. Medications are displayed by alphabetical order of ATC Level 4 classification, then descending
frequency of PT within ATC, and then alphabetically by PT. Subjects were counted only once for each ATC and PT.
[1] ATC Level 4 was not definable for these preferred terms due to multiple ingredients that cannot be mapped to an ATC Level 4 term, route of administration and indication that is not
defined in an ATC Level 4 term, or some similar circumstance.
Reference Listing: 16.2.9.7
Programming note: ATC & PT text should be presented as is from the dataset. If medications are coded but are missing ATC Class Level 4, display as “NOT DEFINED [1]” in the ATC Class Level 4
row and include footnote [1]; otherwise remove footnote [1] from the table.

imputation steps were used for monotone and non-monotone missing data. For monotone missing pattern, a predictive mean matching model was used to impute missing value
for a subject at particular visit having IGA score at previous study visit, treatment group, and pooled site group as independent variables and outcome at study visit as dependent
variable. For non-monotone missing IGA values, Markov-Chain Monte Carlo (MCMC) method was used to impute the data at intermediate visits to make the missing data
pattern into monotone before applying the predictive mean matching multiple imputation algorithm. Percentages are n/Number of subjects in the ITT population within planned
treatment at each visit*100. Baseline is the last non-missing measurement taken on or before the day of first application of study drug.
[1] IGA Success (“Yes”) is defined as an IGA score of “Clear” or “Almost Clear” plus a ≥2-grade improvement from baseline; “No” otherwise.
[2] 90% and 95% CIs for “Yes” are obtained using Wilson method.
[3] The odds ratio, 90% and 95% CIs, and P value are obtained from Cochran Mantel Haenszel test (stratified by pooled site group and baseline IGA grade) comparing:
ARQ-252 cream (all strengths/dose frequencies) vs vehicle cream (all dose frequencies) and ARQ-252 cream 0.3% (all dose frequencies) vs vehicle cream

Abbreviations: CI = confidence interval; IGA = investigator global assessment.
Note: The success scores were summarized using observed dataset. The odds ratio and P values were summarized using multiple imputation dataset. Separate multiple imputation
steps were used for monotone and non-monotone missing data. For monotone missing pattern, a predictive mean matching model was used to impute missing value for a subject at
particular visit having IGA score at previous study visit, treatment group, and pooled site group as independent variables and outcome at study visit as dependent variable. For
non-monotone missing IGA values, Markov-Chain Monte Carlo (MCMC) method was used to impute the data at intermediate visits to make the missing data pattern into
monotone before applying the predictive mean matching multiple imputation algorithm. Percentages are n/Number of subjects in the ITT population within planned treatment at
each visit*100. Baseline is the last non-missing measurement taken on or before the day of first application of study drug.
[1] IGA ≥2-point Improvement from Baseline (“Yes”) is defined as an IGA score with a ≥2-grade improvement from baseline; “No” otherwise.
[2] 90% and 95% CIs for “Yes” are obtained using Wilson method.
[3] The odds ratio, 90% and 95% CIs, and P value are obtained from Cochran Mantel Haenszel test (stratified by pooled site group and baseline IGA grade) comparing: ARQ-252
cream (all strengths/dose frequencies) vs vehicle cream (all dose frequencies) and ARQ-252 cream 0.3% (all dose frequencies) vs vehicle cream (all dose frequencies).

Repeat this page for the remaining study drugs (ARQ-252 Cream 0.1% QD, and Vehicle Cream (All Dose Frequencies)), showing the same study visits shown
here. Then continue for Weeks 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, and 13.
Abbreviations: BID = twice daily; QD = once daily; SD = standard deviation; WI-NRS = Worst Itch – Numeric Rating Scale.
Note: Subjects are summarized by planned treatment. The WI-NRS pruritus score was determined by asking the subject’s assessment of worst itch over the past
24 hours; average weekly WI-NRS pruritus scores were calculated as the average of the reported (non-missing) WI-NRS pruritus daily diary scores for each study
week. The scale is from 0 to 10, which ranges from “no itch” to “worst imaginable itch”. Baseline is the last non-missing measurement taken before the day of first
application of study drug. Change from baseline is calculated as result – baseline result. Percent change from baseline is calculated as (change from
baseline/baseline)*100.

Abbreviations: QD = once daily; SD = standard deviation; WI-NRS = Worst Itch – Numeric Rating Scale.
Note: Subjects are summarized by treatment received. The WI-NRS pruritus score was determined by asking the
subject’s assessment of worst itch over the past 24 hours; average weekly WI-NRS pruritus scores were calculated as
the average of the reported (non-missing) WI-NRS pruritus daily diary scores for each study week. The scale is from
0 to 10, which ranges from “no itch” to “worst imaginable itch”. Baseline is the last non-missing measurement taken
before the day of first application of study drug. Change from baseline is calculated as result – baseline result. Percent
change from baseline is calculated as (change from baseline/baseline)*100.

Abbreviations: BID = twice daily; CI = confidence interval; IGA = investigator global assessment; NRS = Numeric Rating Scale; QD = once daily.
Note: Percentages are n/Number of subjects in the PNRS2 population within planned treatment at each visit*100. The Pain NRS is the subject’s assessment of worst pain
intensity over the past 24 hours; average weekly Pain NRS scores were calculated as the average of the reported (non-missing) Pain NRS daily diary scores for each study
week. The scale is from 0 to 10, which ranges from 0 = “no pain” and 10 = “worst possible pain”.
Baseline is the last non-missing measurement taken before the day of first application of study drug.
[1] Pain NRS ≥2-point Reduction from Baseline (“Yes”) is defined as an average weekly Pain NRS score with a ≥2-point reduction from baseline; “No” otherwise.
[2] 90% and 95% CIs for “Yes” are obtained using Wilson method.
[3] The odds ratio, 90% and 95% CIs, and P value are obtained from Cochran Mantel Haenszel test (stratified by pooled site group and baseline IGA grade) comparing:
ARQ-252 cream (all strengths/dose frequencies) vs vehicle cream (all dose frequencies) and ARQ-252 cream 0.3% (all dose frequencies) vs vehicle cream
(all dose frequencies).

Repeat this page for the remaining Cohort 2 study drugs (ARQ-252 Cream 0.1% QD, Vehicle Cream QD, and Vehicle Cream BID),
showing the same study visits shown here. Continue for the following study visits, applicable to Cohort 2 only: Week 4, Week 8, and Week
12; put “NA” in the “n” row for Cohort 1 for these visits.
Abbreviations: BID = twice daily; NA = not applicable; QD = once daily; SD = standard deviation.
Note: Subjects are summarized by treatment received. The Week 1 study visit is only applicable to Cohort 1 subjects; the Week 4 through
Week 12 study visits are only applicable to Cohort 2 subjects. Lower scores indicate no evidence of irritation while higher scores indicate
worsening reaction. These assessments should be done prior to the study drug application in the study site. Subjects not meeting this condition
on baseline visit are completely removed from the table summary. Baseline is the last non-missing measurement taken before the first
application of study drug. Change from baseline is calculated as result – baseline result.

Note: Percentages are n/Number of subjects in the Safety population within treatment received*100. Medications were coded using WHO-DDE Global B3 version September 2019.
Concomitant medications are all medications that were continuing or starting after first application of study drug. Medications are displayed by alphabetical order of ATC Level 4
classification, then descending frequency of PT within ATC, and then alphabetically by PT. Subjects were counted only once for each ATC and PT.
[1] ATC Level 4 was not definable for these preferred terms due to multiple ingredients that cannot be mapped to an ATC Level 4 term, route of administration and indication that is not
defined in an ATC Level 4 term, or some similar circumstance.
Reference Listing: 16.2.9.7
Programming note: ATC & PT text should be presented as is from the dataset. If medications are coded but are missing ATC Class Level 4, display as “NOT DEFINED [1]” in the ATC Class Level 4
row and include footnote [1]; otherwise remove footnote [1] from the table.

[1] Treatment received for both cohorts.
[2] This data comes from CRF page and was only collected for subjects in Cohort 2.
[3] Overall compliance will be calculated based on number of applications divided by the expected number of IP applications for each subject. For BID dosing, the expected number of IP applications for each
subject is 30 (Cohort 1) or 170 (Cohort 2 BID) for subjects who completed the study or number of days between first and last application of IP, derived as 2 * (last treatment date - first treatment date + 1), for
subjects who discontinued early from the study. For QD dosing, the expected number of IP applications for each subject is 85 (Cohort 2 QD) for subjects who completed the study or number of days between
first and last application of IP, derived as (last treatment date - first treatment date + 1), for subjects who discontinued early from the study. Number of IP applications is calculated as number of expected IP
applications – missed IP applications as collected in the CRF.

Abbreviations: BID = twice daily; COVID-19 = novel coronavirus disease-19; HECSI = Hand Eczema Severity Index; QD = once daily.
Note: Study day is calculated relative to the date of the first application of study drug. The HECSI is an instrument used in clinical trials to rate the severity of 6 clinical signs of hand eczema and the
extent of the lesions on each of 5 hand areas by use of standard scales. Baseline is the last non-missing measurement taken on or before the day of first application of study drug. Change from
baseline is calculated as result – baseline result. Percent change from baseline is calculated as (change from baseline/baseline)*100.
[1] Treatment received for Cohort 1 and randomized treatment for Cohort 2.
[2] Subscores are calculated as the sum of erythema, infiltration/papulation, vesicles, fissures, scale, and oedema, respectively, scored on a scale of 0 to 3 (none to severe) time is estimated area of
skin involved, graded on a scale of 0 to 4, within a location. The range for each subscore is 0 to 72. Lower scores indicate better outcomes.
[3] The total score is calculated as the sum of all subscores. The range for the total score is 0 to 360. Lower scores indicate better outcomes.
Programming note: Continue for all visits. Programming note: For “Was Assessment Completed?” column, if answer is Yes and answer to question “Yes, did COVID-19 disruption cause or
contribute to a delay in HECSI Collection?” is “Yes”, then display “Yes: COVID-19 Disruption Caused/Contributed to Delay in HECSI Collection”; if answer to COVID-19 question is “No”, only

[2] Total Hand % BSA is calculated as the sum of dorsal % BSA (left hand), dorsal % BSA (right hand), palmar % BSA (left hand), and palmar % BSA (right hand).
Programming note: For “Was Assessment Completed?” column, if answer is Yes and answer to question “Yes, did COVID-19 disruption cause or contribute to a delay in BSA Collection?” is “Yes”,
then display “Yes: COVID-19 Disruption Caused/Contributed to Delay in BSA Collection”; if answer to COVID-19 question is “No”, only display “Yes”.
Similarly, for “Was Assessment Completed?” column, if answer is No and answer to question “If No, did COVID-19 disruption cause or contribute to missed BSA Collection?” is “Yes”, then display
“No: COVID-19 Disruption Caused/Contributed to Missed BSA Collection”; if reason BSA not completed is non-missing, concatenate that reason with the response to “No”, as follows:
“No: COVID-19 Disruption Caused/Contributed to Missed BSA Collection; XXXXXXXXXX”
