SYNOPSIS 
Study Title: A Multicenter, Randomized, Double Blind, Placebo Controlled Exploratory Study to Assess the 
Efficacy and Safety of Acthar® Gel in Subjects With Pulmonary Sarcoidosis 
Protocol Number: MNK14344100 
Type: Phase 4 (US) / Phase 2 (all other countries) 
Condition/Disease:  
Pulmonary Sarcoidosis 
Approximate Number of 
Subjects: 100 
Approximate Duration of Subject Participation: Up to 14 months.  
Approximate Number of Study 
Centers: Approximately 75 sites 
globally 
Approximate Duration of Study: The estimated study period is 
approximately 4 years from first subject enrolled to last subject last 
visit (completed open-label extension and follow up visit). Expected 
enrollment period is approximately 3 years (first subject enrolled to last 
subject enrolled). 
Objective: The objective of the study is to evaluate the efficacy and safety of Acthar® Gel in the treatment of 
pulmonary sarcoidosis.  
Design:  
This is a multicenter, randomized, double-blind, placebo-controlled exploratory study evaluating the efficacy 
and safety of Acthar Gel in the treatment of pulmonary sarcoidosis. The study will have 3 phases: Screening 
(up to 28 days); double-blind treatment (24 weeks); and an optional open-label, 24 weeks extension. A follow-
up visit will be conducted 4 weeks (± 2 days) after the last dose of IMP is administered. Following signature of 
the ICF and a screening period of up to 28 days, subjects who meet all eligibility criteria will be randomly 
assigned to receive:  
• 
Double-blind treatment: Acthar Gel, 1 mL (80 U) or matching placebo (1 mL) administered twice 
weekly SC for up to 24 weeks. 
• 
Optional open-label treatment: Acthar Gel, 1 mL (80 U) administered twice weekly SC for up to 
24 weeks. 
Subjects will be assigned to treatment in a 1:1 ratio with up to 50 subjects per arm for a total of approximately 
100 subjects. 
Dose reduction of 50% may be implemented once during the study if a subject meets one of the following 
pre-specified safety criteria based on clinical judgment: 
• 
Uncontrolled hypertension (newly developed or worsening of existing hypertension) before/or in 
conjunction with addition/adjustment of antihypertensive therapy. 
• 
Uncontrolled diabetic signs/symptoms (newly developed of worsening of existing diabetes) before/or 
in conjunction with addition/adjustment of antihyperglycemic therapy. 
• 
Unacceptable toxicity defined as any adverse event (AE) of at least moderate intensity not adequately 
controlled by concomitant medication use or other nonstudy drug-related measure. 
The justification for dose reduction will be captured in the eCRF. Subjects will remain on the 40 U or 
matching placebo 2×/week for the remainder of the study. Subjects, who despite dose reduction continue to 
experience from any of the above mentioned AEs, they will be withdrawn from the study due to AE.  
Subjects will be followed every 4 weeks (± 5 days) for 24 weeks (Visit 2 to Visit 8). During each visit 
following randomization, steroid tapering evaluation will occur based on the following algorithm.

Incremental doses of prednisone for the study are 40, 30, 20, 10, 7.5, 5, 2.5, and 0 mg.
A justification for any deviation will be captured in the eCRF. In addition, subjects and physicians will 
complete patient reported outcomes, and safety will be evaluated based on targeted physical examination per 
organ involved, vital signs, imaging, and laboratory test results. Any additional visits, hospitalization, or 
additional tests or imaging performed beyond those dictated by the protocol, at the discretion of the 
investigator (or other disciplines for extra-pulmonary manifestations) will also be captured in the eCRF. 
Following the completion of the double blind phase, subjects will be invited to continue participation in an 
optional Open-label Extension Phase (Visit 9 to Visit 11). Subjects who decline participation in the Open-label 
Extension Phase, or those ineligible, will have their End-of-Treatment visit during Visit 8. 
All subjects will have a follow-up visit 4 weeks (± 2 days) after the last dose of IMP, regardless of treatment 
group, and/or participation in the optional Open-label Extension Phase.
During the optional Open-label Extension Phase, subjects will be treated with Acthar Gel 80 U 2×/week for up 
to 24 weeks. Subjects who had their dose reduced once by half will be treated with Acthar Gel 40 U 2×/week. 
There will be 3 scheduled visits during this phase: Visit 9, 4 weeks (± 5 days) into the extension phase 
(Week 28), Visit 10 (Week 36) and Visit 11 (Week 48). During these visits corticosteroid taper will follow the 
same procedures and algorithm as in the double blind phase. Subjects and physicians will complete patient 
reported outcomes, and safety will be evaluated based on targeted physical examination per organ involved, 
vital signs, imaging, and laboratory test results. Any additional visits, hospitalization, or additional tests or 
imaging performed beyond those dictated by the protocol, at the discretion of the investigator (or other 
disciplines for extra-pulmonary manifestations) will also be captured in the eCRF.
During Visit 11, End-of-Treatment procedures will be completed. 
Responder rate analysis (efficacy endpoints) will be determined by the investigator and an independent 
adjudication. Adjudication will serve to address inter-rater variability. In case of discrepancies, the 
adjudication determination will be utilized for purposes of efficacy endpoint analyses. Likewise, central HRCT 
and CXR readings will be used for the purpose of the imaging efficacy analyses.

vital signs, clinical laboratory abnormalities, and imaging. 
Statistical Methods: 
Summary statistics will be provided for all study variables with descriptive statistics (number of observations, 
mean, SD, median, minimum, and maximum) for numerical (or continuous) variables. Frequency and 
percentages will be calculated for categorical variables. All data will be summarized by treatment groups as 
appropriate. 
Pearson’s chi-squared test will be used to evaluate the treatment difference between treatment groups for the 
categorical response endpoints. The continuous response endpoints will be analyzed using the 2-sample t-test. 
The time-to-event endpoints will be analyzed using the log-rank test. Kaplan-Meier curves will also be 
presented. 
Additional exploratory analyses will be performed as appropriate. Such analyses may include logistic 
regression model, analysis of variance model, and/or mixed-effects model. Subgroup analyses based on 
demographics, baseline characteristics, study compliance, etc, will also be performed. 
Sample Size Justification: 
Formal sample size calculations were not performed. The sample size is based on recent literature of 
comparative studies in sarcoidosis.

SUMMARY OF CHANGES 
The summary of changes presented below reflects the changes made in Version 2 
Amendment 1. Formatting, consistency, and minor editorial changes are not included.  
The primary reason for Version 2 Amendment 1 is to extend this product’s and this study’s 
treatment to countries other than the US, as currently Acthar Gel is only approved in the US. 
Additionally, updates or revisions are established for: study design that is revised to 
exploratory, changing enrollment and study duration timelines, adding WPAI questionnaire 
for collection of data for health economics and outcomes research, adding provisions for 
remote collection of data for those extenuating occasions when visits cannot be made in 
person, adding diary training and reviews, adding monitoring for possible allergic reactions to 
the first dose of Acthar Gel in the Open-label Extension Phase, removing an additional 
definition for SAEs that are not part of the standard definitions, and adding corticosteroid 
tapering for subjects entering the open label study period. Further detail is presented in 
Appendix 1.

a Visits 2 through 11 should occur within ± 5 days of the indicated weeks and should not be scheduled for the day of injection so as not to influence patient reported 
outcomes. Any additional visits, hospitalization, or additional tests or imaging performed beyond those dictated by the protocol, at the discretion of the investigator 
(or other disciplines for extrapulmonary manifestations) will also be captured in the eCRF. 
b Neutral language should be used in describing the study to neutralized placebo effect. 
c Medical history will include smoking history (classified into one the following categories: current smoker; ever smoked [more than 1cigarette/day for more 
than1year]; never smoked), length of sarcoidosis diagnosis, organ involvement, and prior and current medication. Occupational history should also be collected. 
d Every effort should be made for weight to be measured by the same calibrated scale at every visit.  
e Physical examination will also include targeted examination per organ(s) involved. All efforts must be undertaken for the same physician to perform the physical 
examination for each subject (per subject, per organ involved) at each visit.  
f Patient-reported outcomes include: Steroid toxicity questionnaire (Attachment 2); King’s Sarcoidosis Questionnaire (Attachment 4); Fatigue Assessment Scale 
(Attachment 5); Patient's Global Assessment (Attachment 6); Medical Research Council Dyspnea Scale (Attachment 8); Leicester Cough Questionnaire 
(Attachment 9), Work Productivity and Activity Impairment (WPAI) (Attachment 10). Prior to filling out any patient-reported outcomes at Visit 1, training will be 
provided as to the nature, purpose, and best way of filling these out. For example, reading the last question of the Fatigue Assessment Scale carefully. PRO 
assessments should be completed at each visit before undertaking any activities or tests that can influence the reporting. At Visit 8 and Visit 11 both the investigator 
and the subjects will asked independently if they would choose to continue treatment.  
g All efforts must be undertaken for the same physician to perform the Extrapulmonary Physician’s Organ Severity Tool (ePOST), per subject, (Attachment 3) side-
by-side with prior evaluations.  
h Chemistry panel including liver function tests will include: alanine aminotransferase; albumin (total); alkaline phosphatase; aspartate aminotransferase; 
bicarbonate; bilirubin (total); blood urea nitrogen; calcium; chloride; creatinine; creatine phosphokinase; glucose; phosphorus; potassium; protein (total); sodium; 
uric acid. Samples will be collected from subjects who have been fasted for at least 12 hours (drinking water is permitted).

i Lipid profile will include: high density lipoprotein; low density lipoprotein; triglycerides; total cholesterol. Samples will be collected from subjects who have been 
fasted for at least 12 hours. 
j Biomarkers sampling must include RNA and DNA samples (screening only), if genetic Informed Consent Form (ICF) is signed. 
k Hepatitis B surface antigen, hepatitis B core antibody, hepatitis C virus (HCV) antibody, HCV polymerase chain reaction (for subjects positive for HCV antibody 
only).  
l Tuberculosis (TB) will be tested by interferon gamma release assay (IGRA). Central laboratory test results must be negative for subjects to qualify for the study.  
m ECG will include assessment of sinus rhythm, heart rate, PR Interval, RR Interval, QRS Duration, Q-T Interval and QTcB. 
n Full pulmonary function test (PFT) results will include forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), FVC % predicted (NHANES III 
reference values), FEV1/FVC ratio, peak expiratory flow rate (PEFR) or forced exploratory flow at maximum effort (FEFmax), total lung capacity, residual volume, 
diffusing capacity of the lungs for carbon monoxide (DLCO; uncorrected for Hb), DLCO: % predicted and DLCO/alveolar volume.  
o High-resolution computed tomography (HRCT) should be performed within 28 days of Day -1. Both CXR and HRCT should be evaluated side by side by 
investigator/radiologist/central reader for determining if the condition is improving, stable, or deteriorating based on a 5-point Likert score: much worse; worse; 
unchanged; better; much better. The CXR will also include Scadding scoring (Attachment 11).  
p The Six Minute Walk Test (6MWT) would be performed according to the ATS protocol (Attachment 12). Reasons for not performing the 6MWT will be captured 
in eCRF.  
q Subjects (and/or caregivers) will be trained on SC injections using the training tools provided separately. Additional training may be provided during Visit 2 before 
randomization occurs. SC injections training may be forgone if either the subject or caregiver is a medically trained professional.  
r The importance of adhering to treatment will be encouraged at every visit. At Visit 8, IMP will only be dispensed for subjects participating in the optional Open-
label Extension Phase.  
s Dosing will begin after Visit 2 procedures are completed and subject is randomized. The first dose of study drug for all subjects will be administered in the clinic 
and the subject will be observed for at least 1 hour after dosing. For subjects entering the Open Label Extension, the first dose given at Week 24 will be 
administered in the clinic and the subject will be observed for at least 1 hour after dosing.  All other doses will be administered by the subject or the subject’s 
caregiver at home 2×/week, but no dose should be administered on study visit days (see Section 12.3).  
t Corticosteroid taper will follow the specified algorithm. Corticosteroid tapering at Visit 8 is done for patients entering open label extension only. Reasons for 
determining worsening will be captured in the eCRF (FVC, DLCO, imaging, symptoms, other). Justification for any deviations will also be captured in the eCRF. 
u At each visit following signature of the ICF, AE will be reported based on questioning subjects as to new medical conditions since last visit and as to experiencing 
worsening of existing medical conditions since last visit, physical exam, laboratory and imaging findings.

BACKGROUND INFORMATION AND RATIONALE 
6.1. 
Sarcoidosis Overview  
Sarcoidosis is a chronic multisystem granulomatous disease, with a heterogeneous clinical 
presentation and disease course, characterized by the presence of noncaseating granulomas. 
Although sarcoidosis has been identified as a specific disease entity for more than a century, 
the specific cause of sarcoidosis is unknown. Current understanding is that the pathogenesis 
likely includes exposure to one or more, possibly airborne-transmitted antigens (bacterial, 
organic, anorganic), which then trigger an abnormal immune response in a genetically 
predisposed host (Ahmadzai et al., 2014; Chopra et al., 2016; Iannuzzi et al., 2007; 
Judson, 2012; Korsten et al., 2016). The disease may affect any organ system. Pulmonary is 
the most prevalent and is present in over 90% of patients. Ocular, lymph-node, and cutaneous 
manifestations are next in frequency (Al-Kofahi et al., 2016).  
To date, there is no gold standard for diagnosis. Presently, the diagnosis is a clinical one as no 
reliable diagnostic test exists ATS criteria described in Hunninghake et al., 1999). Several 
biomarkers have been explored, including amyloid A, lysozyme, calcium, angiotensin 
converting enzyme, vitamin D, tumor necrosis factor-α, and various interleukins (eg, sIL-2R), 
to name a few. Despite many potential biomarkers being identified for monitoring and 
diagnosis, there is still a lack of adequately specific and sensitive disease markers for clinical 
usage, necessitating further research on these fronts. Accordingly, the diagnosis is based on 
the combination of clinical, radiological and histological (noncaseating epithelioid cell 
granuloma) parameters. In lieu of diagnostic test(s), diagnostic criteria have been developed, 
and while vetted by experts, these are arbitrary and inexact (Chopra et al., 2016; Judson, 2014; 
Ahmadzai et al., 2014).  
Sarcoidosis does not mandate treatment because the disease may never cause symptoms, or 
organ dysfunction may remit spontaneously, in about 2/3 of patients (Iannuzzi et al., 2007), 
and therapy (particularly corticosteroids) is associated with a myriad of significant side 
effects. While the indications for treatment and the optimal treatment approach have not been 
standardized, the general consensus is that treatment should only be administered to avoid 
danger (eg, cardiac or neurologic manifestations) or to improve quality of life. (Judson, 2014; 
Baughman et al., 2012)  
Various expert driven treatment recommendations exist for pulmonary and extra-pulmonary 
manifestations of sarcoidosis, however, the available evidence to guide treatment is limited. 
Corticosteroids are typically the first-line when treatment is required. Several off label 
alternative agents may be used, usually as corticosteroid sparing agents, because of the 
development or concerns of significant corticosteroid toxicity. Although often a small amount 
of corticosteroid may be continued for adequate efficacy. Second-line disease-modifying anti-
sarcoid drugs may include antimetabolites (eg, methotrexate; azathioprine; leflunomide). 
Third-line typically includes anti-tumor necrosis factor-α biological agents (eg, infliximab; 
rituximab; adalimumab). Use of these agents should be individualized based on the patient’s 
potential for toxicity and the organ that is being treated. In the future, there are goals to 
develop “personalized” or “precision” medical care where therapy will be individualized 
based on the patient’s specific clinical features or genetics (Korsten et al., 2016; Judson, 2014; 
Judson, 2012; Baughman et al., 2012; Jamilloux et al., 2017).

Acthar® Gel has been included as third- or fourth-line therapy in several treatment algorithms 
(Korsten et al., 2016; Baughman et al, 2015). Three studies describing safety and efficacy of 
Acthar Gel in pulmonary sarcoidosis were recently published and described as follows.  
The first study was a retrospective chart review of 47 patients with advanced sarcoidosis seen 
at 2 clinical centers who received at least 1 dose of Acthar Gel with at least 6 months of 
posttreatment follow-up. All patients initially received Acthar Gel 80 U intramuscular or SC 
administration twice a week (2×/week). Eighteen patients (37%) discontinued drug within 6 
months due to study participation cost (4 patients), death (2 patients), or drug toxicity 
(11 patients), or noncompliance (1 patient). Of the remaining 29 patients, 11 experienced 
objective improvement in 1 or more affected organs. All but 2 patients noted disease 
improvement or oral glucocorticoid reduction. Twenty-one patients were treated for more than 
6 months (median 274 days). Nineteen patients were taking prednisone at time of starting 
Acthar Gel: 17 had their prednisone dosage reduced by more than 50%, and 1 patient 
discontinued cyclophosphamide therapy. Acthar Gel treatment for at least 3 months was 
associated with objective improvement in a third of the patients. A third of the patients were 
unable to take treatment for at least 3 months (Baughman et al., 2016). 
The second study was a prospective study of 16 patients with chronic pulmonary sarcoidosis 
receiving prednisone therapy with deterioration by at least 5% in FVC in the previous year. 
Acthar Gel was administered at a loading dose of 80 U SC for 10 days. Patients were 
randomized at Day 14 to receive either 40 U or 80 U Acthar Gel 2×/week for 24 weeks. The 
dose of prednisone was modified by the clinician who was blinded to the patient’s dosage of 
Acthar Gel. At Week 24, there was a decrease in the dose of prednisone and improvements in 
DLCO, the King’s Sarcoidosis Questionnaire (general health status), and the Fatigue Scale. 
There was no significant change in FVC % predicted. For the positron emission tomography 
scan, there was a significant fall in the standard uptake value of the lung lesions. Only 
3/8 patients remained on 80 U repository corticotropin for full 24 weeks. There was no 
significant difference in the response to therapy for those treated with 40 U vs 80 U Acthar 
Gel. The authors concluded that Acthar Gel treatment was prednisone-sparing and associated 
with significant improvement in DLCO, positron emission tomography scan, and patient-
reported outcome measures. A dose of 40 U repository corticotropin 2×/week was as effective 
as 80 U Acthar Gel and was better tolerated (Baughman et al., 2017).  
 
 
 
. 
The third study was large case series of patients with advanced symptomatic sarcoidosis 
treated with repository corticotropin injection (RCI). This large case series study describes 
patient characteristics, RCI utilization patterns, concomitant therapies, and physicians’ 
assessments of treatment response. The study included 302 patients (mean age = 51 years; 
52% women) with a mean of 4.8 years since initial diagnosis of sarcoidosis. Most patients 
(76%) had extrapulmonary involvement, primarily in the skin (28%), joints (25%), heart 
(22%), and eyes (22%); 34% had multiple (≥2) organ involvement. The mean duration of RCI 
treatment was 32.5 weeks, with 61.6% of patients continuing RCI therapy for ≥6 months. The 
RCI utilization pattern indicated an individualized approach to therapy, with a higher starting 
dose associated with a shorter duration of therapy compared with a lower starting dose. The 

Protocol MNK14344100

31 
Confidential and Proprietary 
percentage of patients who used corticosteroids decreased from 61.3% during the 3 months 
before initiation of RCI to 12.9% at 3 months after RCI therapy; the mean daily dose of 
corticosteroid decreased from 18.2 mg to 9.9 mg. The proportion of patients given 
<10 mg/day of prednisone increased from 21% before RCI use to 47% at 3 months after RCI 
use. According to physicians’ assessments of change in patients’ health status after RCI 
therapy, overall status improved in 95% of patients, overall symptoms in 73%, lung function 
in 38%, and inflammation in 33%. The findings suggest that RCI is a viable treatment option 
for patients with advanced symptomatic sarcoidosis and provide insights on patient 
characteristics and practice patterns to help clinicians determine appropriate use 
(Chopra et al., 2019). 
Several studies of various agents (eg, infliximab, ustekinumab, golimumab; 
Baughman et al., 2006; Judson, 2014b; Gibson et al., 1996) have highlighted important issues 
that may confound trial results, including selecting patients with active disease, identifying 
IMP effects in patients receiving concomitant corticosteroids, and establishing proper study 
endpoints. Establishment of an appropriate endpoint is probably the single most challenging 
issue in the design of a clinical sarcoidosis trial (Judson, 2014). The appropriate endpoint in 
sarcoidosis is dependent upon whether one wishes to measure the degree of granulomatous 
inflammation, the physiologic impact of that inflammation, or the effect of physiologic 
impairment on the patient’s quality of life. This is a particularly important distinction in 
sarcoidosis, where active granulomatous inflammation may not significantly impair 
physiology or cause significant symptoms. Ideally, a clinically useful intervention in 
sarcoidosis should demonstrate a reduction in granulomatous inflammation that results in 
improved physiology and quality of life. Thus, multiple endpoints are likely needed to 
demonstrate clinical benefit (Baughman et al., 2012; Baughman et al, 2015).  
The WASOG Diseases Task Force suggested that clinical endpoints for pulmonary 
sarcoidosis should be based on 4 broad categories: PFT, chest imaging, quality of life, and 
steroid-sparing. A composite score that include 2 or more of these categories was proposed as 
more effective than individual scores; however, these have not been rigorously tested 
(Baughman et al, 2015).  
Clinical endpoints to measure disease activity in other systems affected by sarcoidosis such as 
skin, cardiac, ocular, and neurological endpoints are also planned for much needed attention 
by WASOG Disorders Task Force (Baughman et al, 2015).  
6.2. 
Acthar Gel Overview 
Acthar Gel is a naturally sourced complex mixture of ACTH analogs and other pituitary 
peptides. It is approved by the FDA for the treatment of symptomatic sarcoidosis 
(Mallinckrodt ARD LLC, 2019). ACTH is a member of the family of structurally related 
peptides known as melanocortin peptides. Melanocortin peptides, which in addition to ACTH 
include α-, β-, and γ-melanocyte stimulating hormones, are derived from the natural protein 
pro-opiomelanocortin and exert their physiologic effects by binding to cell surface G-protein 
coupled receptors known as melanocortin receptors (MCR) (Mountjoy et al, 1992). Five 
subtypes of MCRs have been identified to date (MC1R to MC5R), each with different tissue 
distributions, binding affinity characteristics, and physiological roles (Getting, 2006). MCRs 
play a key role in regulating inflammation and other cellular function (Catania, 2010). Acthar 
engages MCRs expressed on immune cells and other tissues throughout the body and is

thought to produce both an indirect anti-inflammatory effect and a direct cell effect 
(Catania, 2010; Wright et al., 2019; Olsen et al., 2015; Healy, 2017a; Wright et al., 2019b). 
Production of cortisol is mediated by activation of MC2Rs primarily expressed on the adrenal 
cortex. In in vitro studies in cultured cells lines expressing MCR1-MCR5, the relative 
functional potency of MCRs was measured. It was shown that 6% of Acthar’s relative 
functional potency occurred at MC2R. The remaining 94% occurred at the other MCRs 
(Wright et al., 2019). These data suggest that Acthar acts directly on cells involved in the 
pathogenesis of disease in addition to its indirect action via corticosteroid stimulation. 
The effects of Acthar on human B-lymphocyte function in vitro were evaluated using highly 
purified B-cell populations cultured in the absence of glucocorticoids and stimulated by 
recombinant interleukin-4 and cluster of differentiation 40 ligand as specific B-cell activating 
signals. Immunoglobulin G was measured in supernatants from healthy human peripheral B 
cells that had been cultured for 6 days. The percentage of cells that divided and 
immunoglobulin G production were assessed under basal conditions (unstimulated) or 
stimulated with interleukin-4/cluster of differentiation 40 ligand plus vehicle. Acthar reduced 
B cell proliferation and immunoglobulin G production independent of cortisol release 
(p<0.05, compared to vehicle-treated group) (Olsen et al., 2015; Healy, 2017aHealy_2017, 
Healy, 2017b). In further experiments to explore the direct effects of Acthar on human 
macrophages and focusing on induction of pro-inflammatory mediators following 
lipopolysaccharide stimulation, Acthar inhibited the production of the pro-inflammatory 
cytokines interleukin-6 and tumor necrosis factor (p<0.0001, compared to vehicle-treated 
group; (Healy, 2017aHealy_2017, Healy, 2017b). These data further demonstrate a direct 
effect of Acthar on immune cell modulation independent of cortisol release. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
. 
While the exact mechanism of action of Acthar Gel is still unknown, further investigation is 
being conducted. This information is based on nonclinical data and pharmacodynamic data 
and the relationship to clinical benefit is unknown.

6.3. 
Rationale 
This study will provide additional data to support the efficacy and safety of Acthar Gel in 
pulmonary sarcoidosis.  
The Acthar Gel dose and dosing regimen for this study, namely 80 U 2×/week, are informed 
by patterns of clinical use in sarcoidosis, 2 recently published studies (Baughman et al., 2016; 
Baughman et al., 2017) and the package insert.  
The prescribing information for Acthar Gel recommends the use of 40 U to 80 U administered 
intramuscularly or SC every 24- to 72 hours in adults and children over 2 years of age; the 
specific dose is individualized according to the medical condition 
(Mallinckrodt ARD LLC, 2019).  
6.4. 
Risk and Benefits 
The most common adverse reactions for Acthar Gel are similar to those of corticosteroids and 
include fluid retention, alteration in glucose tolerance, elevation of blood pressure, behavioral 
and mood changes, increased appetite, and weight gain. Acthar Gel may also be associated 
with increased susceptibility to new infection and increased risk of exacerbation, 
dissemination, or reactivation of latent infections. For a complete reference of known 
potential risks please refer to the Acthar Gel product labeling (Mallinckrodt ARD LLC, 2019).

7.1. 
Objective 
The objective of this study is to evaluate the efficacy and safety of Acthar Gel in the treatment 
for pulmonary sarcoidosis. 
7.2. 
Assessments of Efficacy  
The following assessments will be performed during this study: 
• STS, a newly developed composite endpoint.  
• PFT. 
• Imaging: HRCT; CXR (including Scadding Score). 
• Corticosteroid tapering. 
• Physician Global Assessment. 
• Patient-reported outcomes: King’s Sarcoidosis Questionnaire; Fatigue Assessment 
Scale; Patient's Global Assessment.  
• Symptom Assessments: Medical Research Council Dyspnea Scale; Leicester 
Cough Questionnaire; steroid toxicity questionnaire. 
• Functional testing: 6MWT (including the Borg Scale). 
• ePOST. 
• Biomarkers (including RNA and DNA samples (screening only), if genetic ICF is 
signed).

7.2.1. 
Sarcoidosis Treatment Score 
This is a newly developed composite score that combines the results of PFT, chest imaging, 
quality of life, and changes in corticosteroid dosing as recommended by the WASOG task 
force (Baughman et al., 2015) and based on the results of the Acthar Gel prospective study; 
(Baughman et al., 2017). Individuals may score from -6 to +6. Higher scores indicate 
improvement.

Subject tolerating Acthar Gel (or placebo) will be categorized according the following 
scoring:  
• Response is defined as scores of ≥ 3/6 points.  
• Partial Response is defined as scores of 2/6 points or stable with corticosteroid 
reduction (ie, a total score of +1 due to ≥ 50% reduction in corticosteroid dosage).  
• Non Response is defined as scores of ≤ 1/6 points without significant 
corticosteroid taper (stable or deterioration). 
 
7.2.2. 
Pulmonary Function Tests 
PFTs are routinely used in the evaluation of pulmonary sarcoidosis patients. However, there is 
no diagnostic pattern in PFTs. The most prevalent pattern of PFTs is restrictive lung disease, 
although obstruction can nevertheless also be present, either in isolation or concomitantly. 
FVC is most commonly used to measure response to therapy. Nonetheless, the volume of 
FVC does not correlate clinically with symptoms of dyspnea, and there is no definite 
consensus on how to follow changes in FVC in response to treatment. Based on 
intrapulmonary fibrosis, in the absence of better data, a decline of ≥ 5% (absolute change of 
predicted) FVC is consistent with refractoriness in sarcoidosis patients (Korsten et al., 2016; 
Baughman et al., 2015).

Acthar® Gel (Repository Corticotropin Injection) 
Protocol Version 2 Amendment 1 
 
36 
Confidential and Proprietary 
Diffuse lung capacity of carbon monoxide has also been used. However, there is a higher 
intra-subject variability than FVC. Significant reduction in DLCO may indicate refractory 
pulmonary disease in the absence of pulmonary arterial hypertension as a cause of drop in 
DLCO (Korsten et al., 2016; Baughman et al., 2015). 
PFT will follow ATS/European Respiratory Society task force for standardization of lung 
function testing (Miller et al., 2005) and the revisions provided for DLCO 
(Graham et al., 2017).  
PFT results will include FEV1, FVC, FVC % predicted (NHANES III reference values), 
FEV1/FVC ratio, PEFR or FEFmax, TLC, RV, DLCO (uncorrected for Hb), DLCO % 
predicted and DLCO/VA at screening visit, Visits 5, 8, 10, and 11 (every 12 weeks).  
At the randomization visit, spirometry results will include FEV1, FVC, FVC % predicted 
(NHANES III reference values), FEV1/FVC ratio and PEFR or FEFmax. 
Patients should be instructed to avoid smoking within at least 1 hour of testing, consuming 
alcohol within 4 hours of testing, performing vigorous exercise within 30 minutes of testing, 
wearing clothing that substantially restricts full chest and abdominal expansion, and eating a 
large meal within 2 hours of testing. Ideally, when patients return for repeat testing, the 
equipment and the operator should be the same, and the time of day should be within 2 hours 
of previous test times. The order of the tests should be kept constant for each subject on each 
subsequent PFT.  
7.2.3. 
Imaging (HRCT; CXR) 
Although granulomas are microscopic structures, sarcoidosis granulomas have a proclivity to 
coalesce into macroscopic nodular conglomerations that are capable of being detected with 
plain radiographic or HRCT radiographic techniques. HRCT reveals more sarcoidosis lung 
involvement than the CXR including, identifying more parenchymal and mediastinal/hilar 
disease as well as parenchymal details to reliably differentiate from other diffuse lung 
diseases. HRCT findings have been correlated with lung pathology and have been proposed as 
a biomarker of disease activity.  
The intriguing observations of chest radiographs in sarcoidosis published by Scadding in 1961 
(Scadding, 1961; Attachment 11) are still considered the gold standard because of the limited 
use of radiation and its association with resolution or progression of the disease although these 
stages do not necessarily progress or regress from one to another. However, interobserver 
variability and lack of association with functional clinical parameters (eg, PFT, 6MWT) are 
limiting factors (Korsten et al., 2016; Chopra et al., 2016). 
Imaging will be evaluated by the investigator/ radiologist and the central reader to determine 
if the condition is improving, stable, or deteriorating based on a 5-point Likert score: much 
worse; worse; unchanged; better; much better.

7.2.4.
Corticosteroid Tapering
Corticosteroids are typically the first- line when treatment of sarcoidosis is required. Concerns 
of significant corticosteroid toxicity results in efforts to taper as early as possible. There is 
little consensus regarding the optimal algorithm for tapering corticosteroids (Judson, 2014). 
Subjects will be evaluated at each visit (following randomization) and the following algorithm 
will be used to taper the corticosteroid dosage: 
Incremental doses of prednisone for the study are 40, 30, 20, 10, 7.5, 5, 2.5, and 0 mg 
(Baughman et al., 2002).

King’s Sarcoidosis Questionnaire
The King’s Sarcoidosis Questionnaire (Attachment 4) is a 28 item questionnaire for subjects 
to indicate the status of their sarcoidosis and treatment (Patel et al., 2013). Higher scores 
indicate improvement. A change of 4 points is considered clinically meaningful. 
7.2.7.
Fatigue Assessment Scale (FAS)
The Fatigue Assessment Scale (Attachment 5) is a 10 item checklist for subjects to indicate 
their level of fatigue (De Vries et al., 2004). Lower scores indicate improvement (less 
fatigue). A change of 4 points is considered clinically meaningful. 
7.2.8.

The 6MWT (Attachment 12) is objective evaluation of functional exercise capacity. It is a 
practical test that requires a 100-ft hallway but no exercise equipment or advanced training. It 
measures the distance walked on a flat, hard surface during the period of 6 minutes (treadmill 
are not recommended). The 6MWT evaluates the global and integrated responses of all the 
systems involved during exercise, including the pulmonary and cardiovascular systems, 
systemic circulation, peripheral circulation, blood, neuromuscular units, and muscle 
metabolism. It does not provide specific information on the function of each of the different 
organs and systems involved in exercise or the mechanism of exercise limitation, as is 
possible with maximal cardiopulmonary exercise testing. Changes in 6MWT after therapeutic 
interventions correlate with subjective improvement in dyspnea.  
The 6MWT will be performed according to ATS guidelines with an improvement of 
≥ 30 meters being considered as meaningful. Repeat testing should be performed about the 
same time of day to minimize intraday variability. The Borg Scale is used to compare 
shortness of breath and fatigue between baseline prior to the 6MWT test and upon completion 
of the 6MWT test (ATS, 2002).  
7.2.13. 
Extrapulmonary Physician Organ Severity Tool (ePOST) 
The ePOST examines 18 extrapulmonary organs and assigns a score to each one (0 = not 
affected to 6 = very severely affected). The state of sarcoidosis is evaluated at each visit, by 
the investigator. Investigators use all clinical information available to them, including 
laboratory analyses, and assessments by subspecialists to assess each organ system. Scores are 
calculated by the ePOST score divided by the number of extrapulmonary organs involved at 
any time during the study (Judson et al., 2008).  
7.2.14. 
 Biomarkers/genomics  
As stated in Section 6.1, despite many potential biomarkers being identified for monitoring 
and diagnosis, there is still a lack of adequately specific and sensitive disease markers for 
clinical usage, necessitating further research on these fronts. Accordingly, biomarkers levels 
will be collected as an exploratory assessment and compared between Screening, and every 
12 weeks (up to 48 weeks for those subjects participating in the optional Open-label

Extension Phase). These may include angiotensin-converting enzyme, sIL-2R and 
vitamin D 1,25. The final determination as to the selection of biomarkers will be made based 
on the evolution of the science and emerging guidance closer to the completion of the study.  
Genomic profile (optional) will be assessed based on the evolution of science at the time of 
study completion. 
7.2.15. 
Work Productivity and Activity Impairment 
The WPAI is a validated assessment of work and activity impairment associated with health 
problems (Zhang et al., 2010). This questionnaire is to be completed by subjects. When this 
assessment is required, it should be the first assessment done at any visit (with the subject 
completed efficacy questionnaires) and must be completed prior to any study drug dosing.  
Subjects will be provided a quiet, private place to complete the assessment. Subjects will be 
instructed to answer all questions to the best of their ability and without help from others 
(including study staff, relatives, or friends). Subjects may refrain from answering any 
question. 
The study staff should review the questionnaire after it is completed and encourage the 
subjects to complete any missing information. Study staff will record the refusal of subjects to 
answer any questions in the source documents. 
7.3. 
Efficacy Endpoints 
The endpoints for the efficacy objective are: 
• STS response rate at 24 weeks (Visit 8). 
• STS response rate at 48 weeks (Visit 11). 
• Physician and subject independent responses to the question “Would you choose to 
continue current treatment?” at 24 and 48 weeks. 
• Time to response as evaluated at earlier time points (Weeks 4 to 20) as determined 
by the investigator based on clinical judgment and the following parameters: 
o Patient reported outcomes. 
o Corticosteroid tapering. 
o Patient Global Assessment. 
o Physician Global Assessment  
o PFT (at applicable time points). 
o ePOST.  
o Supportive efficacy endpoints per applicable time points.

for those subjects participating in the optional Open-label Extension Phase). Serum aliquots 
will be kept for each of these time points. Possible biomarkers include angiotensinogen, 
sIL-2R and vitamin D 1,25. The final selection of biomarkers will be made based on the 
scientific knowledge and emerging guidance closer to the completion of the study.  
The genomic profile (optional) will be assessed based on the understanding of genetic factors 
at the time of study completion.

STUDY DESIGN 
8.1. 
Description 
This is a multicenter, randomized, double-blind, placebo-controlled exploratory study 
evaluating the efficacy and safety of Acthar Gel in the treatment of pulmonary sarcoidosis. 
The study will have 3 phases: Screening (up to 28 days); double blind treatment (24 weeks); 
and an optional open-label, 24 weeks extension. A follow-up visit will be conducted 4 weeks 
(± 2 days) after the last dose of IMP is administered. 
Following signature of the ICF and a screening period of up to 28 days, subjects who meet all 
eligibility criteria will be randomly assigned to receive either 1 mL (80 U) of Acthar Gel or 
1 mL of a matching placebo SC 2×/week. Subjects will be assigned to treatment in a 1:1 ratio 
with up to 50 subjects per arm for a total of approximately 100 subjects. 
Dose reduction of 50% may be implemented once during the study, if a subject meets one of 
the following prespecified safety criteria based on clinical judgment: 
• Uncontrolled hypertension (newly developed or worsening of existing 
hypertension) before/or in conjunction with addition/adjustment of 
antihypertensive therapy. 
• Uncontrolled diabetic signs/symptoms (newly developed of worsening of existing 
diabetes) before/or in conjunction with addition/adjustment of antihyperglycemic 
therapy. 
• Unacceptable toxicity defined as any AE of at least moderate intensity not 
adequately controlled by concomitant medication use or other non IMP-related 
measure 
The justification for dose reduction will be captured in the eCRF. Subjects will remain on the 
40 U or matching placebo 2×/week for the remainder of the study. Subjects who, despite dose 
reduction, continue to experience any of the above mentioned AEs, (meet a criteria as above) 
or experience another event will be withdrawn from the study due to AE (Section 12.3).  
Subjects will be followed every 4 weeks (± 5 days) for 24 weeks (Visit 2 to Visit 8). During 
each visit following Visit 2, steroid tapering evaluation will occur based on the corticosteroid 
tapering algorithm (Section 7.2.4). A justification for any deviation will be captured in the 
eCRF. 
In addition, subjects and physicians will complete patient reported outcomes, and safety will 
be evaluated based on targeted physical examination per organ involved, vital signs, imaging, 
and laboratory test results. Any additional visits, hospitalization, or additional tests or imaging 
performed beyond those dictated by the protocol, at the discretion of the investigator (or other 
disciplines for extra-pulmonary manifestations) will also be captured in the eCRF. Following 
the completion of the double blind phase, subjects will be invited to continue participation in 
an optional Open-label Extension Phase (Visit 9 to Visit 11). 
Subjects who decline participation in the Open-label Extension Phase, or those ineligible, will 
have their End-of-Treatment visit during Visit 8.

All subjects will have a follow-up visit 4 weeks (± 2 days) after the last dose of IMP, 
regardless of treatment group and/or participation in the optional Open-Label Extension 
Phase. 
During the optional Open-label Extension Phase, subjects will be treated with Acthar Gel 
80 U 2×/week for an additional 24 weeks. Subjects who had their dose reduced once by half 
will be treated with Acthar Gel 40 U 2×/week. There will be 3 scheduled visits during this 
phase. Visit 9, 4 weeks into the extension phase (Week 28), Visit 10 (Week 36) and Visit 11 
(Week 48). During these visits corticosteroid tapering will follow the same procedures and 
algorithm as in the double blind phase. Subjects and physicians will complete patient reported 
outcomes, and safety will be evaluated based on targeted physical examination per organ 
involved, vital signs, imaging, and laboratory test results. Any additional visits, 
hospitalization, or additional tests or imaging performed beyond those dictated by the 
protocol, at the discretion of the investigator (or other disciplines for extrapulmonary 
manifestations) will also be captured in the eCRF. 
During Visit 11 End-of-Treatment procedures will be completed. Responder rate analysis 
(efficacy endpoints) will be determined by the investigator and an independent adjudication. 
Adjudication will serve to address inter-rater variability. In case of discrepancies, the 
adjudication determination will be utilized for purposes of efficacy endpoint analyses. 
Likewise, central HRCT readings and CXR will be used for the purpose of the imaging 
efficacy analyses. 
8.2. 
Approximate Duration of Subject Participation 
Subjects will participate in the study for a total of approximately 14 months, including a 
screening period of up to 28 days, a double blind treatment period of 24 weeks, and an 
optional open-label extension period of an additional 24 weeks, and a follow up visit 4 weeks 
(± 2 days) after final dose of IMP. 
 
8.3. 
Approximate Duration of Study 
The duration of the study from first subject first visit to last subject last visit will be dependent 
on the ability of the site(s) to identify and enroll eligible subjects. The entire study is expected 
to require approximately 4 years to complete. 
8.4. 
Approximate Number of Subjects 
Approximately 100 subjects will be globally enrolled at approximately 75 sites.

INVESTIGATIONAL MEDICINAL PRODUCT 
Acthar Gel is a naturally sourced complex mixture of ACTH analogs and other pituitary 
peptides in 16% gelatin for intramuscular or SC injection. Acthar Gel contains 0.5% phenol, 
not more than 0.1% cysteine (added), sodium hydroxide and/or acetic acid to adjust pH, and 
water for injection. Acthar Gel is obtained from processing porcine pituitary using an FDA 
approved process. Sarcoidosis is an approved indication for Acthar Gel 
(Mallinckrodt ARD LLC, 2019). 
Placebo is a sterile preparation of 16% gelatin for intramuscular or SC injection. Placebo 
contains 0.5% phenol, not more than 0.1% cysteine, sodium hydroxide and/or acetic acid to 
adjust pH, and water for injection. The placebo formulation is identical to Acthar Gel except 
that it contains no active medication. 
12.1. 
Methods of Assigning Subjects to Treatment Groups 
12.1.1. 
Randomization  
Subjects will be randomized according to computer-generated allocation scheme to receive 
either Acthar Gel 1 mL (80 U) or placebo 1 mL administered 2×/week. Both investigators and 
the subjects will be blinded to the treatment assignment. A block randomization will be 
performed. The biostatistician will decide on the details at the time of the creation of the 
randomization scheme. 
12.1.2. 
Interactive Telephone/Web Response System 
The investigator or designee will contact IXRS to register subjects at Screening (Visit 1). The 
subject’s identification number (ID) will be determined by the IXRS and will be used to 
identify the subjects for the duration of the study within all systems and documentation. 
Subject identification numbers will consist of 7 digits: the first 4 digits reflect the site number 
assigned to the Investigator and the last 3 digits are the subject number. 
A subject ID number will not be assigned to more than 1 subject. If a subject is not eligible to 
receive treatment, or should a subject discontinue from the study, the subject ID number 
cannot be reassigned to another subject. 
In the event that a subject is rescreened within the screening window, they do not need a new 
subject ID number. At the Randomization Visit, qualified subjects who meet all of the 
eligibility criteria will be randomized into the study.  
The investigator or designee must contact the IXRS to report a subject as a screen failure if 
the subject does not meet eligibility criteria prior to randomization. 
The investigator or designee must contact IXRS to record each subject visit, to receive the 
IMP assignments, and to report any subject status changes. 
The investigator must maintain a subject master log linking the subject ID to the subject’s 
name. The investigator must follow all applicable privacy laws in order to protect a subject’s 
privacy and confidentiality. Information that could identify a subject will be masked on 
material received by the sponsor.

12.2. 
Identification of Investigational medicinal product  
When knowledge of the IMP assignment is required for the medical management of an 
individual subject, the investigator may obtain the treatment assignment of the subject 
experiencing the AE or SAE. The treatment blind for that subject may be broken by accessing 
the IXRS using instructions provided in the Study Operations Manual. The investigator must 
notify the sponsor’s MM or physician designee before unblinding, if at all possible, or 
immediately after unblinding the treatment assignment. The investigator and sponsor should 
make every effort to document and limit the subjects who are unblinded to the treatment 
assignment. The investigator must also indicate in source documents that the blind was broken 
and provide the date and reason for breaking the blind.  
12.3. 
Dosing Procedures 
Both Acthar Gel and placebo are supplied as 5 mL multidose vials. Acthar Gel vials contain 
80 U of ACTH per mL. Vials will be labeled according to all applicable national and local 
regulations.  
The vials should be warmed to room temperature before using. The vials should not be over 
pressurized; assure that no excess air (beyond the volume of product to be withdrawn) is 
inserted into the vial prior to withdrawing the product. After use the vial should be returned to 
refrigeration.  
Subjects or their caregivers will administer SC injections of Acthar Gel or placebo after 
randomly assigned to treatment at Visit 2. The subject or subject’s caregiver will administer 
the first dose of study drug and the first dose of Acthar Gel in the Open-Label at Week 24 in 
the clinic under the supervision of study staff. The subject will remain in the clinic for at least 
1 hour postdose to monitor for allergic or anaphylactic reactions. All other doses will be 
administered by the subject or the subject’s caregiver at home, but no dose should be 
administered on study visit days. 
IMP cannot be taken on 2 consecutive days and cannot be taken more than 3 days apart. 
Therefore the following dosing schedule should be recommended to subjects at Visit 2, dose 
administration on either Monday and Thursday, Tuesday and Friday, or Wednesday and 
Saturday, and would be determined by the day of the week Visit 2 occurred.  
In the double-blind treatment period Acthar Gel, 1 mL (80 U) or matching placebo (1 mL) 
will be administered twice weekly SC for up to 24 weeks. In the optional open-label 
extension, Acthar Gel 1 mL (80 U) will be administered SC twice weekly for up to 24 weeks. 
If a dose reduction of IMP is deemed necessary, a reduction of 50% (40 U) may be 
implemented once during the study based on safety criteria previously defined (see 
Section 8.1). The justification for dose reduction will be captured in the eCRF.  
Subjects who, despite dose reduction, continue to experience any of the AE defined in 
Section 8.1, will be withdrawn from the study due to AE.  
Subject who required dose reduction (50%) will inject 40 U (0.5mL) throughout the study, 
including during the optional Open-label Extension Phase, if applicable.

12.3.1. 
Treatment Discontinuation 
Should any of the following occur, treatment with IMP may be reduced once by 50% 
(Section 8) or should be discontinued:  
• Development of accelerated hypertension (defined as systolic blood pressure 
≥ 180 mm Hg and/or diastolic blood pressure ≥ 100 mm Hg) that cannot be 
managed by the adjustment of concomitant medications such as antihypertensive 
medications. 
• Development of congestive heart failure (Class III or IV) that cannot be managed 
by the adjustment of concomitant medications such as diuretics and 
antihypertensive medications. 
• Development of uncontrolled diabetic signs/symptoms that cannot be managed by 
the adjustment of concomitant medications such as insulin and oral hypoglycemic 
agents.  
• Development of any other AE of at least moderate intensity and possibly, probably 
or definitely related to IMP that cannot be managed by the adjustment of 
concomitant medications. 
If the subject is withdrawn due to an AE, all efforts should be made to complete end-of-
treatment procedures (Visit 8, Section 11.5) as soon as deemed possible and follow-up 
procedures (Visit 12, Section 11.9). If applicable, the suitability of subject continuing into the 
optional Open-label Extension Phase will be determined by the investigator.  
12.4. 
Storage of Clinical Supplies 
Acthar Gel and placebo will be maintained in a temperature controlled, secure locked area 
with restricted access at the study site.  
Both Acthar Gel and Placebo will be supplied in kits containing the appropriate amount of 
vials. Both Acthar Gel and placebo will be stored under refrigeration between 2°to 8°C 
(36°to 46°F). Please refer to the Pharmacy Manual for complete information regarding storage 
and accountability of IMP.  
12.5. 
Drug Accountability 
In accordance with US FDA and ICH requirements, the investigator will, at all times, be able 
to account for all IMP furnished to the study site. A drug accountability record will be 
maintained for this purpose. The investigator must maintain accurate records indicating dates 
and quantity of IMP received, to whom it was dispensed (subject-by-subject accounting) and 
accounts of any IMP accidentally or deliberately destroyed. All unused IMP not involved in 
immediate subject dosing will be maintained under locked, temperature-controlled storage at 
the study site.  
12.6. 
Compliance Monitoring 
Prior to beginning the administration of IMP, subjects and/or their caregiver will be trained on 
dosing and SC injection, and must exhibit proper technique of SC administration during initial 
IMP administration at Visit 2. Subjects and/or their caregiver will be trained on the

completion of the study diary and will complete study diary entries to record all study drug 
administration and will bring it, along with all study drug kits including used vials to each 
visit. Used and unused vials will be inspected. Number of expected, administered doses and 
reason for discrepancies will be documented. Each time study drug is dispensed compliance 
will be encouraged. Subject diary training is an ongoing process as the diary will be reviewed 
with the subject at each visit to monitor compliance with study drug administration.

SAFETY ASSESSMENTS AND PROCEDURES 
Overall safety will be determined by the incidence, severity and relationship of AEs, physical 
examinations, vital signs, clinical laboratory abnormalities, and imaging. All safety 
assessments will be performed at times outlined in the Schedule of Study Events (Table 1). 
Additional (unscheduled) safety assessments may be performed as needed. 
14.1. 
Adverse Events 
AEs will be recorded from signing of the ICF and followed by the investigator until the AE is 
resolved or stabilized or at such time as the investigator refers the subject to a nonstudy 
physician for follow-up treatment. Any and all safety measures (which includes standard of 
care activities) should be provided by the study site to the subject. Any study site follow-up 
should be documented. 
Refer to Section 16 for additional details on the handling of AEs and SAEs. 
14.2. 
Medical and Surgical History  
Medical and surgical history will be obtained at Screening (Visit 1). Medical history will 
include a review of the following systems: general, dermatological, respiratory, 
cardiovascular, gastrointestinal, genitourinary, gynecological (when applicable), endocrine, 
musculoskeletal, hematological, neuropsychological, immune (allergies), and head, eyes, ears, 
nose, and throat. Historical and current medical conditions including and date of last 
menstrual period for female subjects will be recorded. Occupational history will also be 
collected.  
14.3. 
Physical Examination 
A complete physical examination will be performed at all visits and will include evaluation of 
the head, eyes, ears, nose, throat, neck (including thyroid), cardiovascular system (including 
assessment of heart, peripheral pulses, presence or absence of edema), lungs, abdomen 
(including liver and spleen, bowel sounds), lymph nodes, musculoskeletal system (including 
spine, joints, muscles) neurological system (including cranial nerves, reflexes, sensation, 
strength), skin, extremities and other conditions of note. Special emphasis will be made to 
sarcoidosis manifestations per organ involvement.  
The findings of the physical examinations will be recorded. Any changes in medical 
conditions, specifically new medical conditions and worsening of existing medical conditions 
will be recorded as AE, as appropriate. 
14.4. 
Vital Signs 
Vital signs will be obtained after the subject has been seated for 5 minutes (minimum) and 
will include systolic and diastolic blood pressures, pulse rate, and respiratory rate. 
The investigator may perform additional unscheduled vital sign measurements to evaluate or 
manage a suspected AE. These unscheduled vital sign measurements should be obtained after 
the subject has been seated for at least 5 minutes, if possible. Unscheduled vital signs will be 
recorded. 
The date and time for all vital sign assessments will be recorded.

Clinical Laboratory Tests 
The clinical laboratory tests are listed in Attachment 1. Tests should be conducted as 
described in the Schedule of Study Events (Table 1). All clinical laboratory tests will be done 
at a central laboratory facility except for urine analysis, and urine pregnancy test which will 
be performed at the local laboratory. Specific instructions for collection, processing, storage, 
and shipment of clinical laboratory samples will be provided in a separate laboratory manual, 
where appropriate. 
Samples for serum chemistry testing for all visits will be collected under fasting conditions (at 
least 12 hours, drinking water is permitted). The date and time of the sample collection must 
be documented on the laboratory report. Investigators must review and sign laboratory 
reports. The clinical significance of each laboratory abnormality will be documented. New 
clinically significant laboratory abnormalities or clinically significant changes in laboratory 
values will be reported as AEs, as appropriate. 
In addition: 
All female subjects of child bearing potential will have a serum pregnancy test at Screening 
(Visit 1). Urine pregnancy tests will be done at all other visits throughout the study. Results 
must be available prior to dosing with IMP. Subjects with positive results will be ineligible for 
study entry (Visit 1 or Visit 2) or immediately withdrawn from the study (Visit 3 through 
Visit 11) and the pregnancy reported as per Section 16.5. 
HBsAg and HBcAb will be performed at Screening (Visit 1). Results of these tests must be 
negative or nonreactive for subjects to qualify for the study.  
HCV will be performed at Screening (Visit 1). A positive HCV will automatically trigger a 
HCV PCR analysis. HCV PCR must be < 25 IU/mL to qualify for the study. 
IGRA for TB will be performed at Screening (Visit 1). Results of this test must be negative 
for subjects to qualify for the study. 
Out-of-Range Laboratory Values 
Laboratory values from samples collected at Screening (Visit 1) will be evaluated by the 
investigator for eligibility of the subject in the study. Clinical laboratory tests may be repeated 
once to determine subject eligibility. 
Laboratory values from scheduled or unscheduled laboratory assessments that fall outside the 
reference range from samples collected during the study or at study exit or early 
discontinuation will be assessed by the investigator for clinical significance. If the out of 
range value for samples is deemed clinically significant by the investigator, an AE will be 
recorded.  
14.6. 
12-Lead Electrocardiogram 
Electrocardiogram will include assessment of sinus rhythm, heart rate, PR Interval, RR 
Interval, QRS Duration, Q-T Interval and QTcB. 
A 12-lead ECG will be obtained for all subjects at Screening (Visit 1) and Visits 8 and 11. 
The date of the ECG must be documented on the ECG tracing. An appropriately trained and 
experienced physician must interpret this ECG. Date, time, and clinical parameters from the

all ECGs will be entered in the eCRF. At the discretion of the investigator a repeat ECG may 
be collected at the screening visit to confirm findings.  
Additional ECGs may be performed any time throughout the study if deemed clinically 
necessary and entered into eCRF.

STATISTICAL METHODS AND PLANNED ANALYSIS 
15.1. 
General Considerations 
This section provides a general description of the statistical methods to be used in analyzing 
both safety and efficacy data. The key statistical issues or considerations will be addressed in 
more detail in a statistical analysis plan to be provided as a separate document that will be 
finalized prior to database lock. The analyses for the double-blind phase data will be 
performed after the database lock for the double-blind phase.  
Unless otherwise specified, all statistical tests, when applicable, will be 2-sided with a 
significance level of 0.05. Summary statistics will be provided for all study variables with 
descriptive statistics (number of observations, mean, SD, median, minimum, and maximum) 
for numerical (or continuous) variables. Frequency and percentages will be calculated for 
categorical variables. All data will be summarized by treatment groups as appropriate. Data 
summary and analyses will be performed with SAS 9.4 or higher. 
15.2. 
Analysis Populations 
The following populations will be identified and analyzed in this study: 
A Modified Intent-to -Treat (mITT) Population that includes all randomized subjects who 
receive at least 1 dose of IMP and who contribute any efficacy data to the study will be used 
for the efficacy analyses. A Safety Population that includes all randomized subjects who 
receive at least 1 dose of IMP will be used for all the safety analyses. 
15.3. 
Subject Characteristics 
15.3.1. 
Demographics 
The demographic information will be summarized for each analysis population by treatment 
group. 
15.3.2. 
Medical and Surgical History 
Prior medical conditions or procedures will be summarized by body system and treatment 
group. 
15.3.3. 
Prior and Concomitant Medications 
Prior and concomitant medications will be coded according to the WHO Drug Dictionary. The 
incidence (number and percent) of prior and concomitant medication use will be summarized 
by treatment group.  
15.3.4. 
Subject Disposition and Exposure to Investigational Medicinal Product 
Subject disposition and treatment exposure will be summarized. The number of subjects who 
complete the study and who do not complete the study along with the reasons for 
discontinuation from the study will be summarized.

Adverse Events 
The MedDRA coding terms will be used for coding AEs. The number of AEs and the number 
of subjects reporting AEs will be listed and summarized descriptively by body system, 
preferred term, severity, and causality for each treatment group. Only TEAEs (events that are 
new in onset or aggravated in severity following treatment), will be included in all summaries. 
SAEs and deaths will be summarized.  
15.4.2. 
Clinical Laboratory Tests 
Clinical laboratory test results will be summarized descriptively and presented in data listings.  
15.4.3. 
Physical Examination Findings 
All physical examination results will be summarized descriptively and presented in a data 
listing. 
15.4.4. 
Electrocardiogram Findings 
Electrocardiogram measured changes from baseline for sinus rhythm, heart rate, PR interval, 
RR interval, QRS duration, Q-T Interval, and QTcB will be summarized.  
15.4.5. 
Vital Signs 
Vital sign results (heart rate, diastolic/systolic blood pressures, respiratory rate and weight) 
and corresponding changes from baseline values will be summarized at each visit with 
descriptive statistics by treatment group.  
15.5. 
Efficacy Analysis  
Efficacy analyses will be performed on the mITT Population. All efficacy endpoints will be 
summarized and analyzed. Pearson’s chi-squared test will be used to evaluate the treatment 
difference between treatment groups for the categorical response endpoints. The continuous 
response endpoints will be analyzed using 2-sample t-test. The time-to-event endpoints will be 
analyzed using log-rank test. Kaplan-Meier curves will also be presented. 
Additional exploratory analyses will be performed as appropriate. Such analyses may include 
logistic regression model, analysis of variance model, and/or mixed-effects model. Subgroup 
analyses based on demographics, baseline characteristics, study compliance, etc, will also be 
performed. 
Missing data imputations will be performed as appropriate. In general, the last-observation-
carried-forward method will be used to impute missing data. Additional missing data 
imputation may be performed as needed. 
15.6. 
Interim Analysis 
No interim analysis of the data is planned.

ADVERSE EVENTS AND SERIOUS ADVERSE EVENTS 
16.1. 
Safety 
For safety information about Acthar Gel, refer to the most recent version of the Package Insert 
(Mallinckrodt ARD LLC, 2019).  
16.2. 
Definitions 
AE  
An AE is any untoward or undesirable medical occurrence in a subject who is administered an 
IMP, which does not necessarily have to have a causal relationship with this treatment. 
Examples of AEs include but are not limited to: 
• Clinically significant laboratory findings. 
• Clinically significant changes in physical examination findings. 
• An AE occurring due to IMP overdose whether accidental or intentional. 
• An AE occurring from investigational medicinal abuse. 
• An AE associated with investigational medicinal withdrawal. 
• Unexpected AE. 
An unexpected AE is defined as an AE, the nature and severity of which is not consistent with 
the applicable product information in the most recent version of the package insert 
(Mallinckrodt ARD LLC, 2019). 
Adverse experiences (serious or non-serious) that commonly occur in the study population or 
background regimen will be considered anticipated events. Such events include known 
consequences of the underlying disease (disease-related) or condition under investigation (eg, 
symptoms, disease progression) and events unlikely to be related to the underlying disease or 
condition under investigation but common in the study population independent of drug 
therapy. Anticipated events, when reported, to be associated with the use of the investigational 
product, are a subset of unexpected AEs (events not listed in the package insert 
[Mallinckrodt ARD LLC, 2019]). However, these events do not warrant expedited reporting 
as individual cases when serious criteria have been met because it is not possible to determine 
that there is a reasonable possibility that the drug caused the event. As a result, they do not 
meet the definition of a suspected adverse reaction. 
SAE  
An SAE is defined as any untoward medical occurrence that at any dose 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. 

Protocol MNK14344100 
Acthar® Gel (Repository Corticotropin Injection) 
Protocol Version 2 Amendment 1 
 
72 
Confidential and Proprietary 
• Results in 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, 
may jeopardize the subject and may require medical or surgical intervention to prevent one of 
the outcomes listed above. Examples of such medical events include allergic bronchospasm 
requiring intensive treatment in an emergency department or at home, blood dyscrasias or 
convulsions that do not result in inpatient hospitalization, or the development of drug 
dependency or drug abuse.  
Death  
Death is an outcome of an event. The event that resulted in death should be recorded and 
reported on the SAE Form. All causes of death must be reported as SAEs. The investigator 
should make every effort to obtain and send death certificates and autopsy reports (if 
applicable) to Mallinckrodt. 
Life-Threatening Event  
A life-threatening event refers to immediate risk of death as the event occurred per the 
reporter. A life-threatening event does not include an event that, had it occurred in a more 
severe form, might have caused death but, as it actually occurred, did not create an immediate 
risk of death. For example, hepatitis that resolved without evidence of hepatic failure would 
not be considered life-threatening, even though hepatitis of a more severe nature can be fatal. 
Similarly, an allergic reaction resulting in angioedema of the face would not be life-
threatening, even though angioedema of the larynx, allergic bronchospasm, or anaphylaxis 
can be fatal. 
Hospitalization  
Hospitalization is defined as an official admission to a hospital. Hospitalization or 
prolongation of a hospitalization constitutes a criterion for an AE to be serious; however, it is 
not in itself considered an SAE. In absence of an AE, a hospitalization or prolongation of a 
hospitalization should not be reported by the investigator as an SAE. Such situations include, 
but are not limited to, the following: 
• A hospitalization or prolongation of hospitalization is needed for a procedure 
required by the protocol. 
• A hospitalization or prolongation of hospitalization is part of a routine procedure 
followed by the center (eg, stent removal after surgery). This should be recorded in 
the study file. 
• A hospitalization for a preexisting condition that has not worsened. 
• Note that the following hospitalizations are not considered SAEs in Mallinckrodt 
clinical studies:  
o A visit to the emergency department or other hospital department of less than 
24 hours that does not result in admission (unless considered "important 
medical event" or life-threatening event).

Adverse Event and Serious Adverse Event Classifications 
Investigational Medicinal Product Relatedness 
The following classifications should be used when evaluating the relationship of AEs or SAEs 
to study treatment (Table 3). 
Table 3:  
AE Relationships 
Relationship 
Definition 
Not Related 
No relationship between the experience and the administration of study 
treatment; related to other etiologies such as concomitant medications or 
subject’s clinical state. 
Unlikely Related 
The current state of knowledge indicates that a relationship is unlikely. 
Possibly Related 
A reaction that follows a plausible temporal sequence from administration of 
the study treatment and follows a known response pattern to the suspected 
study treatment. The reaction might have been produced by the subject’s 
clinical state or other modes of therapy administered to the subject. 
Related 
A reaction that follows a plausible temporal sequence from administration of 
the study treatment and follows a known response pattern to the suspected 
study treatment and can be confirmed with a positive re-challenge test or 
supporting laboratory data. 
 
Severity Assessment 
For purposes of consistency, if required, the investigator may use the intensity grades 
presented in Table 4.  
Table 4:  
AE Severity Grades 
Grade 
Definition 
Mild 
Does not interfere with subject's usual function and activities 
Moderate 
Interferes to some extent with subject's usual function and activities 
Severe 
Interferes significantly with subject's usual function and activities 
 
If an AE increases in severity (eg, from moderate to severe); decreases in severity (eg, 
changes from moderate to mild); or there is a change in seriousness, a new AE will be opened 
and the original AE will be closed. If an AE is still ongoing at the time of a subject’s 
completion of the final visit, the resolution/stop date and time is left blank.  
To ensure there is no confusion or misunderstanding of the difference between the terms 
“serious” and “severe,” which are not synonymous, the following note of clarification is 
provided: 
The term “severe” is used to describe the intensity (severity) of a specific event (as in mild, 
moderate, or severe myocardial infarction); the event itself, however, may be of relatively 
minor medical importance (such as a severe headache). This is not the same as “serious,”

Confidential and Proprietary 
which is based on the subject/event outcome or action criteria usually associated with events 
that pose a threat to a subject's life or functioning. Seriousness (not severity) serves as a guide 
for defining regulatory reporting obligations. 
16.4. 
Adverse Event and Serious Adverse Event Recording and 
Reporting 
AEs and SAEs will be recorded from signing of the ICF through completion of the follow-up 
visit, which will take place 4 weeks (± 2 days) after the subject has received the last 
administration of IMP. The investigator is required to record the AE or SAE regardless of the 
severity of the event or its relationship to study treatment. The investigator must follow up on 
all AEs and SAEs until the event has resolved or stabilized or at such time the investigator 
refers the subject to a nonstudy physician. The investigator will document the further follow-
up information in the subject’s source document.  
During the period specified above, the investigator will: 
Record all AEs and SAEs in the source documents from the signing of the ICF through the 
completion of the follow-up telephone call.  
Record all AEs and SAEs in the eCRF from the initial IMP dose through the completion of 
the follow-up telephone call.  
Report all SAEs on an SAE Report Form to Mallinckrodt Pharmacovigilance. 
Report all pregnancies to Mallinckrodt Pharmacovigilance on the Pregnancy Surveillance 
Form. 
Submit the Safety Alert from Mallinckrodt to the IRB/IEC. (Submit any Expedited Safety 
Report or Suspected Unexpected Serious Adverse Reaction from Global Pharmacovigilance 
to the IRB/IEC.) 
The reporting requirements for AEs are summarized in Table 5.

All fields on the AE CRF page should be completed for each event with a full description of 
the event and date and time of onset/start and resolution/stop. A medical diagnosis if known, 
should be recorded in lieu of each individual sign and symptom associated with the diagnosis 
and experienced by the subject. If no medical diagnosis is known, the term used by the subject 
to describe the event or signs noted by the site personnel should be recorded.  
SAEs 
Initial Reporting 
SAEs (based on US FDA/ICH definition of an SAE) require immediate reporting to 
Mallinckrodt Global Pharmacovigilance or designated representative.  
• For all fatal or life-threatening events, the investigator, or designee, must report 
information to the MM. 
• For all SAEs, the investigator, or designee, must complete the SAE Report Form 
with the minimum information required by US FDA and ICH and fax it to 
Mallinckrodt Global Pharmacovigilance or designee within 24 hours of first 
knowledge of the event even if the experience does not appear to be related to the 
IMP. 
• The investigator, or designee, will receive acknowledgement of receipt of the SAE 
Report Form from Mallinckrodt. 
• If there is any doubt about whether the information constitutes an SAE, the 
information is to be treated as an SAE. 
The investigator(s) or designee is required to submit the Safety Alert to the responsible 
IRB/IEC. 
The sponsor will submit safety reports to the US FDA and other regulatory agencies, as 
appropriate. 
Follow Up Reporting  
The investigator or designee must complete an SAE Report Form for all follow-up 
information received and fax or e-mail it to Mallinckrodt Global Pharmacovigilance or 
designee within 24 hours of receipt (eg, detailed written descriptions that include copies of 
relevant subject records, autopsy reports and other supporting documents). The investigator(s) 
or designee will receive acknowledgement of receipt for each SAE Report Form from 
Mallinckrodt. 
• The investigator or designee is required to provide all related 
information/supporting documentation of an SAE until the SAE is resolved or 
stabilized or the subject has been referred to a nonstudy physician for follow-up 
treatment.  
• The investigator(s) or designee is required to submit the Safety Alert to the 
responsible IRB/IEC.  
• The sponsor will submit safety reports to the US FDA. (The sponsor will ensure 
that any Expedited Safety Report or Suspected Unexpected Serious Adverse 
Reaction are submitted to the FDA and other regulatory agencies as appropriate).

16.5. 
Pregnancy Reporting 
Certain information, although not considered an SAE, must be recorded, reported, and 
followed up as indicated. This includes the following:  
Pregnancy exposure to an IMP, except for exposure to prenatal vitamins. Subjects should not 
become pregnant during the study. If the subject becomes pregnant, study treatment must be 
discontinued immediately. The investigator must report the pregnancy by submitting the 
appropriate form to Mallinckrodt Global Pharmacovigilance within 24 hours of confirmation 
of a pregnancy (ie, positive serum or urine pregnancy test result). The outcome of pregnancy 
(eg, spontaneous abortion, live birth, still birth, congenital anomalies, birth defects) must be 
reported by submitting the appropriate form to Mallinckrodt Global Pharmacovigilance within 
24 hours of the pregnancy outcome being submitted to the study site. If the pregnancy results 
in a live birth, a post-delivery follow-up will be performed at least 28 days after the baby is 
born and must be reported to Mallinckrodt Pharmacovigilance within 24 hours of the study 
site becoming aware of the follow-up information. Both maternal and paternal IMP exposures 
are collected.  
If the female partner of a male subject becomes pregnant during the study, the site will 
forward the appropriate forms to Mallinckrodt Global Pharmacovigilance or designee, within 
24 hours of being notified. The outcome of pregnancy (eg, spontaneous abortion, live birth, 
still birth, congenital anomalies, birth defects) must be reported by submitting the appropriate 
form to Mallinckrodt Global Pharmacovigilance or designee within 24 hours of the pregnancy 
outcome being submitted to the study site. If the pregnancy results in a live birth, a 
postdelivery follow-up will be performed at least 28 days after the baby is born and must be 
reported to Mallinckrodt Global Pharmacovigilance or designee within 24 hours of the study 
site becoming aware of the follow-up information.

SUBJECT DISCONTINUATION OR WITHDRAWAL 
17.1. 
Subject Withdrawal 
Subjects who discontinue, or are withdrawn from the study for any reason, will be required to 
have the early termination safety and efficacy assessment procedures (Visit 8, see 
Section 11.5) as well as follow up procedures (Visit 12, see Section 11.9).  
The reason for discontinuation will be recorded. A subject may be discontinued from the 
study for the following medical or administrative reasons: 
Withdrawal by Subject 
Subjects will be free to discontinue from the study at any time. Subjects who have received at 
least 1 dose of IMP but do not complete the study will not be replaced. 
AE 
If a dosed subject experiences an AE that, in the judgment of the investigator, sponsor or MM, 
presents an unacceptable consequence or risk to the subject, the subject will be discontinued 
from IMP. In addition, subjects who experience any of the AEs described in Section 12.3.1 
may have their dose reduced by 50% once or discontinued (Section 17). 
Death 
In the event that a subject dies during the study, death will be the reason for discontinuation. 
Lost to Follow-up 
Every effort should be made to maintain contact with subjects during their participation in the 
study. A subject may be considered lost to follow-up if there is no response to 3 attempts to 
reach the subject by telephone or electronically and no response to a certified letter sent to the 
last known address of the subject. Efforts to contact the subject should be noted in source 
documentation. 
Met Withdrawal Criteria 
Discontinuation from IMP is mandated if the subject becomes pregnant or receives live or 
live-attenuated vaccines. 
Worsening of Disease Activity 
Subjects may be withdrawn if, in the opinion of the investigator, there is a lack of efficacy 
during the study.  
Other 
If the above reasons are not applicable, please use the “Other” option and provide the 
appropriate reason for subject withdrawal.

STUDY SUSPENSION, TERMINATION, AND COMPLETION 
The sponsor may suspend or terminate the study or part of the study at any time for any 
reason. If the investigator suspends or terminates the study, the investigator will promptly 
inform the sponsor and the IRB/IEC and provide them with a detailed written explanation. 
Upon study completion, the investigator will provide the sponsor, IRB/IEC, and regulatory 
agency with final reports and summaries as required by regulations. Study termination and 
follow-up will be performed in compliance with Mallinckrodt standard operating procedures.

PROTOCOL AMENDMENTS 
Any change in the study plan requires a protocol amendment or an administrative letter. An 
investigator must not make any changes to the study without IRB/IEC and sponsor approval 
except when necessary to eliminate apparent immediate hazards to the subjects. A protocol 
change intended to eliminate an apparent immediate hazard to subjects may be implemented 
immediately, but the change must then be documented in an amendment, reported to the 
IRB/IEC within 5 working days, and submitted to the appropriate regulatory agency in the 
required time frame, if appropriate.

QUALITY CONTROL AND ASSURANCE 
The sponsor performs quality control and assurance checks on all clinical studies that it 
sponsors. Before enrolling any subjects in this study, sponsor personnel and the investigator 
review the protocol, the eCRFs and instructions for their completion, the procedure for 
obtaining informed consent, and the procedure for reporting AEs and SAEs. A qualified 
representative of the sponsor will monitor the conduct of the study.  
Study and Study Site Discontinuation Criteria 
The sponsor, investigator, MM or local and national regulatory authorities may discover 
conditions during the study that indicate that the study or study site should be terminated. This 
action may be taken after appropriate consultation between the sponsor and investigator. 
Conditions that may warrant termination of the study/study site include, but are not limited to: 
• The discovery of an unexpected, serious, or unacceptable risk to the subjects 
enrolled in the study. 
• The decision on the part of the sponsor to suspend or discontinue testing, 
evaluation or development of the IMP. 
• Failure of the investigator to enroll subjects into the study at an acceptable rate. 
• Failure of the investigator to comply with pertinent regulations. 
• Submission of knowingly false information from the study site to the sponsor, 
study monitor, or local and national regulatory authorities. 
• Insufficient adherence to protocol requirements 
• Study/study site termination and follow-up will be performed in compliance with 
Mallinckrodt standard operating procedures.

DIRECT ACCESS, DATA HANDLING, AND RECORD-
KEEPING 
21.1. 
Investigator 
The investigator will permit study-related monitoring, audits, IRB/IEC review, and regulatory 
inspections by providing direct access to original source data and documents. 
All subject information recorded in the eCRF will be attributable to source data from the 
investigational site. Each subject’s eCRF should be fully completed and submitted to the 
Sponsor in a timely fashion. If an investigator retires, relocates, or otherwise withdraws from 
conducting the study, the investigator must notify the sponsor to agree upon an acceptable 
storage solution. Regulatory agencies will be notified with the appropriate documentation. 
Any significant changes in study personnel will require an updated Statement of Investigator 
(ie, US FDA form 1572) to be filed with the sponsor. 
The investigator must notify their IRB/IEC of protocol violations in accordance with local 
regulatory and IRB/IEC requirements. 
21.2. 
Sponsor 
The eCRF data are stored in a database and processed electronically. The sponsor’s MM 
reviews the data for safety information. The data are reviewed for completeness, and logical 
consistency. Automated validation programs will identify missing data, out-of-range data, and 
other data inconsistencies. Clinical laboratory data will be processed electronically. Requests 
for data clarification are forwarded to the study site for resolution.

SUBJECT INJURY 
In general, subject to specific provisions in the clinical trial agreement, if a subject is injured 
as a direct result of an IMP, the sponsor will pay for reasonable and necessary medical 
treatment for the injury, to the extent that such expenses are not covered by the subject’s 
medical insurance, a government program, or other responsible third party. If laws or 
regulations of the locality in which the study is taking place require additional payment of

RECORDS RETENTION 
The investigator shall retain and preserve 1 copy of all data collected or databases generated 
in the course of the study, specifically including but not limited to those defined by GCP as 
essential. Essential documents should be retained until at least 2 years after the last approval 
of a marketing application in an ICH region and until there are no pending or contemplated 
marketing applications in an ICH region or at least 2 years have elapsed since the formal 
discontinuation of clinical development of the IMP. These documents should be retained for a 
longer period, however, if required by the applicable regulatory requirements or by an 
agreement with the sponsor. It is the responsibility of the sponsor to inform the 
investigator/institution as to when these documents no longer need to be retained. Prior to 
destruction of any study essential documents, the investigator must first obtain written 
approval from the sponsor.

BIOLOGICAL SAMPLES 
Blood samples will be used only for scientific research. Each sample will be labeled with a 
code so that the laboratory personnel testing the samples will not know the subject’s identity. 
After the study ends, the clinical laboratory samples will be destroyed, with the exception of 
samples for biomarker and genomic analysis. Samples for biomarker analysis and optional 
genetic testing will be retained at a biologic storage facility for future testing for no more than 
5 years following the completion of the study. The subject may request that his or her 
samples, if still identifiable, be destroyed at any time; however, any data already collected 
from that sample will still be used for this research.

patients with advanced symptomatic 
sarcoidosis treated with repository 
corticotropin injection (RCI). This large 
case series study describes patient 
characteristics, RCI utilization patterns, 
concomitant therapies, and physicians’ 
assessments of treatment response. The 
study included 302 patients 
(mean age = 51 years; 52% women) with a 
mean of 4.8 years since initial diagnosis of 
sarcoidosis. Most patients (76%) had 
extrapulmonary involvement, primarily in 
the skin (28%), joints (25%), heart (22%), 
and eyes (22%); 34% had multiple (≥2) 
organ involvement. The mean duration of 
RCI treatment was 32.5 weeks, with 
61.6% of patients continuing RCI therapy

for ≥6 months. The RCI utilization 
pattern indicated an individualized 
approach to therapy, with a higher 
starting dose associated with a shorter 
duration of therapy compared with a 
lower starting dose. The percentage of 
patients who used corticosteroids 
decreased from 61.3% during the 3 
months before initiation of RCI to 12.9% 
at 3 months after RCI therapy; the mean 
daily dose of corticosteroid decreased 
from 18.2 mg to 9.9 mg. The proportion of 
patients given <10 mg/day of prednisone 
increased from 21% before RCI use to 
47% at 3 months after RCI use. 
According to physicians’ assessments of 
change in patients’ health status after RCI 
therapy, overall status improved in 95% 
of patients, overall symptoms in 73%, 
lung function in 38%, and inflammation 
in 33%. The findings suggest that RCI is a 
viable treatment option for patients with 
advanced symptomatic sarcoidosis and 
provide insights on patient characteristics 
and practice patterns to help clinicians 
determine appropriate use (Chopra et al., 
2019).

publications related to 
MCRs  
pituitary peptides. Further down in the 
same paragraph: 
MCRs play a key role in regulating 
inflammation and other cellular function 
(Catania, 2010). Acthar engages MCRs 
expressed on immune cells and other 
tissues throughout the body and is thought 
to produce both an indirect anti-
inflammatory effect and a direct cell effect 
(Catania, 2010; Wright et al., 2019; Olsen 
et al., 2015; Healy, 2017a; Wright et al., 
2019b). Production of cortisol is mediated 
by activation of MC2Rs primarily 
expressed on the adrenal cortex. In in 
vitro studies in cultured cells lines 
expressing MCR1-MCR5, the relative 
functional potency of MCRs was 
measured. It was shown that 6% of 
Acthar’s relative functional potency 
occurred at MC2R. The remaining 94% 
occurred at the other MCRs (Wright et 
al., 2019). These data suggest that Acthar 
acts directly on cells involved in the 
pathogenesis of disease in addition to its 
indirect action via corticosteroid 
stimulation. 
The effects of Acthar on human B-
lymphocyte function in vitro were 
evaluated using highly purified B-cell 
populations cultured in the absence of

glucocorticoids and stimulated by 
recombinant interleukin-4 and cluster of 
differentiation 40 ligand as specific B-cell 
activating signals. Immunoglobulin G was 
measured in supernatants from healthy 
human peripheral B cells that had been 
cultured for 6 days. The percentage of 
cells that divided and immunoglobulin G 
production were assessed under basal 
conditions (unstimulated) or stimulated 
with interleukin-4/cluster of 
differentiation 40 ligand plus vehicle. 
Acthar reduced B cell proliferation and 
immunoglobulin G production 
independent of cortisol release (p<0.05, 
compared to vehicle-treated group) 
(Olsen et al., 2015; Healy, 2017a, Healy, 
2017b). In further experiments to explore 
the direct effects of Acthar on human 
macrophages and focusing on induction of 
pro-inflammatory mediators following 
lipopolysaccharide stimulation, Acthar 
inhibited the production of the pro-
inflammatory cytokines interleukin-6 and 
tumor necrosis factor (p<0.0001, 
compared to vehicle-treated group; 
(Healy, 2017a, Healy, 2017b). These data 
further demonstrate a direct effect of 
Acthar on immune cell modulation 
independent of cortisol release.

The WPAI is a validated assessment of 
work and activity impairment associated 
with health problems (Zhang et al, 2010). 
This questionnaire is to be completed by 
subjects. When this assessment is 
required, it should be the first assessment 
done at any visit (with the subject 
completed efficacy questionnaires) and 
must be completed prior to any study 
drug dosing.  
Subjects will be provided a quiet, private 
place to complete the assessment. Subjects 
will be instructed to answer all questions 
to the best of their ability and without 
help from others (including study staff, 
relatives, or friends). Subjects may refrain 
from answering any question.  
The study staff should review the 
questionnaire after it is completed and 
encourage the subjects to complete any 
missing information. Study staff will 
record the refusal of subjects to answer 
any questions in the source documents.
