Appendix references, including clarifying all 
Appendix references to ensure alignment with 
appropriate Appendix. 
• Sections 12.5.1.3, (clinical laboratory data) 
12.5.1.4 (vital signs) and 12.5.1.5 (ECG) have 
been revised to remove hypothesis tests. These 
data will be summarized but not tested. 
Additionally, QTc values of clinical importance 
have been added as Table 6 in Section 12.5.1.5. 
• Section 12.5.2.1 has been revised to clarify that 
the treatment estimate of the clinical response 
rate at the end of the Maintenance Phase and its 
associated two-sided 95% confidence interval 
(CI) will be obtained from a repeated measures 
generalized estimating equation (GEE) model 
with a logit link using SAS PROC GENMOD 
GLIMMMIX with LSMEANS statement.  Also 
that the longitudinal model will include visit, 
the concurrent CS medical conditions (diabetes, 
hypertension) as Baseline covariates as well as 
age (rounded median split), sex, disease 
duration, prior CS therapy, and prior radiation 
therapy, and subject will be included as a 
random effect.  The previous text regarding 
time trends has been deleted. 
• In Section 12.5.2.2 the analysis of Salivary and 
Serum Cortisol has been revised to clarify that 
change from Baseline, percent change from 
Baseline and at-visit values will be listed and 
summarized descriptively by visit, and a paired 
t-test will be used to compare post-baseline 
values with baseline values, for each visit. 
• In Section 12.5.2.2 for the analysis of CS 
Comorbidity Biomarkers, it has been clarified 
that the longitudinal model will include visit, 
the concurrent CS medical conditions (diabetes,

hypertension) as Baseline covariates as well as 
age (rounded median split), sex, disease 
duration, prior CS therapy, and prior radiation 
therapy, and subject as a random effect.  The 
analysis of time trends and McNemar’s tests 
have been deleted. 
• In Section 12.5.2.2 for the analysis of the 
Glucose Tolerance Test and Spot Albumin, a 
paired t-test has been added for each 
assessment. 
• Section 12.5.2.3 it is no longer planned to 
perform the exact binomial test and 95% CI for 
and medication changes so these have been 
removed. Additionally, the text regarding 
additional exploratory analyses has been 
deleted as it is redundant. 
• Addition of cross-referencing throughout. 
• Reference was added (Schindler) for 
classification and pharmacology of progestins. 
• Added DL0 to Appendix A. 
• Appendix A, footnote 6 has been clarified to 
indicate that Spaulding ECGs are to be 
performed at each visit during Maintenance and 
Extended Evaluation phases monthly.

• 
To assess the proportion of subjects with complete or partial response (defined for the 
initial inference of efficacy as ≥50% reduction of 24-hour UFC levels from Baseline 
after 6 months of treatment with COR-003 in the Maintenance Phase without dose 
increase) beyond 6 months of treatment (Extended Evaluation Phase); 
• 
To characterize changes in 24- hour UFC levels from Baseline beyond 6 months of 
treatment with COR-003 (Extended Evaluation Phase);  
•

from the Beck’s Depression Inventory II beyond 6 months of treatment with 
COR-003 (Extended Evaluation Phase); 
• 
To evaluate changes in the biomarkers of CS comorbidities (diabetes, hypertension, 
hypercholesterolemia and obesity) beyond 6 months of treatment with COR-003 
(Extended Evaluation Phase); 
• 
To describe the Clinical Benefit after 6 months of treatment with COR-003 in the 
Maintenance Phase, and after 9 and 12 months of treatment (Extended Evaluation 
Phase), defined as follows: 
o Clinical response as indicated by UFC ≤ upper limit of normal (ULN), and 
o No increase in COR-003 dose during Maintenance Phase, and 
o A clinically meaningful improvement in any one Baseline CS comorbidity 
(diabetes, hypertension, hypercholesterolemia, weight) as defined in the 
Statistical Analysis Plan (SAP), and  
o No study drug related treatment-emergent adverse event (TEAE) classified as 
severe or worse. 
• 
To assess changes in anti-diabetic, anti-cholesterol and antihypertensive therapies 
after 6 months of treatment with COR-003 in the Maintenance Phase, and after 9 and 
12 months of treatment (Extended Evaluation Phase); 
• 
To assess the change in clinical signs of hypercortisolism obtained from standardized 
photographs and rated by an adjudication committee after 3 and 6 months of 
treatment with COR-003 in the Maintenance Phase, and after 12 months of treatment 
(Extended Evaluation Phase). 
Pharmacokinetic/Pharmacodynamic:  
• 
To evaluate the pharmacokinetics (PK) of COR-003 in subjects with CS;  
• 
To explore the dose-response relationship for safety, including dose-response for 
adverse events of special interest (AESI) such as QTc if data allow; 
• 
To explore the dose-response relationship for reduction of UFC levels if data allow. 
Methodology:  This is a single arm, open label, dose titration study to assess efficacy, safety, 
tolerability, and PK of COR-003 in subjects with endogenous CS as illustrated below.  The 

Cortendo AB 
 
Protocol COR-2012-01 
AMENDMENT 6 
Page 15 of 119 
CONFIDENTIAL 
 
range of effective doses for COR-003 in this CS population will also be established.  
Following an initial screening and washout period, as applicable, this study will be conducted 
in three treatment phases as follows: 
• 
Dose Titration Phase:  approximately 2 to 21 weeks to achieve an effective and 
tolerable maximum dose (the Therapeutic Dose); 
• 
Maintenance Phase:  6 months of treatment at the Therapeutic Dose following the 
Dose Titration Phase; 
• 
Extended Evaluation Phase: 6 months of continued treatment after the Maintenance 
Phase.  
 
After signing the informed consent, subjects will enter the Screening Phase. After the initial 
assessments, subjects on previous CS medical therapies or other prohibited medications must 
enter a washout period before completing all Screening assessments detailed in the Time and 
Events Table. Baseline measurements will be obtained as part of the Screening assessments 
after washout and completion of all initial Screening procedures.  If a subject does not meet 
the eligibility requirements, they might be eligible to re-screen but only if their underlying 
condition has changed in the interim such that they are now likely to meet study eligibility 
criteria. Such re-screenings will be exceptional circumstances, and all re-screenings require 
prior permission of the study Medical Monitor before they begin. 
After confirmation of eligibility at the Baseline Visit including confirmation of increased UFC 
levels as per eligibility requirements, subjects will enter into the Dose Titration Phase. Dose 
titration will occur in increments of 150 mg with a starting dose of 150 mg twice daily (BID) 
over a period of approximately 2 to 21 weeks to achieve an effective and tolerable maximum 
dose (the Therapeutic Dose). Decisions for dose increases will be based on each subject’s 
tolerability, assessment of UFC levels and safety data.  Dose decreases may also occur based 
on subject’s tolerability and safety data. 
Subjects that reach total daily doses of >600 mg/day will be monitored more closely and will 
be asked to return 7 days (±3 days) following each dose escalation visit at total daily doses 
>600 mg/day for an additional safety evaluation. Subjects will be advised to contact the 
Investigator immediately in the event of developing symptom-specific adverse events (AE), 
such as adrenal insufficiency or other AEs at any time.  
Once the Therapeutic Dose has been reached and confirmed from the mean of a total of four 
adequately collected 24-hour urine collections for UFC measurements, subjects will enter into 
the Maintenance Phase of the study and will be asked to return to the clinic monthly [every 
30 days (±7 days)] for 6 months for assessment of efficacy and safety.  During the 
Maintenance Phase, doses may not be increased to maintain UFC levels at or below ULN of 
the assay unless it is confirmed that a dose increase is deemed medically necessary at the 

Cortendo AB

discretion of the Investigator after discussion with the Medical Monitor. Prior to the End of 
Maintenance Phase Visit, four complete 24-hour urine collections will be obtained and 
subjects may enter the Extended Evaluation Phase.   
In the 6-month Extended Evaluation Phase, subjects will return to the clinical site every 
90 days (±14 days) for safety and efficacy evaluations.  
In order to exclude that a treatment effect is due to delayed onset of radiation therapy, 
previously irradiated subjects must stop treatment with COR-003 for at least 2 weeks after the 
end of the 6-month Maintenance Phase (End of Maintenance Phase Visit) and provide four 
complete 24-hour urine collections for UFC measurements at least 14 days following the End 
of Maintenance Phase Visit.  If the 24-hour UFC results indicate that UFC levels are elevated, 
the subject may subsequently restart therapy and continue into the Extended Evaluation 
Phase, at the discretion of the Investigator.  They should return for their next in-clinic visit for 
study assessments and resupply of study medication every 3 months [every 90 days (± 14 
days)] from the End of Maintenance Visit. 
Throughout the study, safety data will be collected at specified times.  Adequate medical 
coverage will be provided at all times during the course of the study to ensure that prompt 
safety decisions can be made and appropriate medical interventions are provided.  The 
Investigator will provide subjects with instructions on how to access the medical staff 
regardless of day and time in order to obtain medical care. An independent Data Safety 
Monitoring Board (DSMB) will review the safety of the drug throughout the study  
After completion of treatment in this study, subjects who do not extend treatment through the 
expanded access program, will have a Follow-Up Visit (a minimum of 2 weeks and no longer 
than 30 days following the completion of treatment).  Once all study assessments have been 
completed, subjects will be promptly referred back to their endocrinologist (if not the 
Investigator) for further management according to the local standard of care, and based on 
their preceding medical history.  [NOTE: The Follow-Up Visit is not required for subjects 
continuing into expanded access treatment.] 
Number of subjects (planned):  A sufficient number of subjects (estimated at approximately 
90) will be enrolled into the Dose Titration Phase of the study to ensure that at least 
70 subjects complete the 6-month Maintenance Phase.   
Inclusion Criteria:  
Subjects will be eligible for the study if all of the following criteria are met: 
1. Male or female ≥18 years of age 
2. Able to provide written informed consent prior to any study procedures being performed; 
eligible subjects must be able to understand the informed consent form prior to inclusion 
into the study. 
3. Confirmed diagnosis of newly diagnosed, persistent or recurrent Cushing’s disease (CD) 
or endogenous CS of other etiology if subjects are not candidates for surgery or 
radiotherapy within the 18 months after enrollment. 
Previous medical records will be collected and used to support the diagnosis of CD or 
endogenous CS of other etiology, including the following etiologies:   
- 
Ectopic adrenocorticotropic hormone (ACTH) secretion, i.e. ACTH not of pituitary 
origin 
- 
Ectopic corticotropin-releasing hormone (CRH) secretion 
- 
Adrenal-dependent CS (i.e. adrenal adenoma (NOT carcinoma), adrenal hyperplasia, 
etc.) 
- 
Etiology unknown.

In the absence of pathological or post-surgical confirmation of the diagnosis of CD (i.e. 
documented adrenal insufficiency post-adenomectomy or hypophysectomy, which will be 
considered diagnostic). The following historical evidence will be considered satisfactory 
to establish the diagnosis of CD: 
Plasma corticotropin (ACTH) level >20 pg/mL (4.5 pmol/L) or greater (Note: ACTH 
≥5 pg/mL (1.1 pmol/L) and ≤20 pg/mL will generally suffice only if accompanied by 
either a positive CRH stimulation test or Dexamethasone Suppression Test (DST) or 
combined CRH-DST) PLUS one of the diagnostic strategies described below based on 
pituitary magnetic resonance imaging (MRI)/computed tomography (CT) findings (Note: 
pituitary imaging preceding the original diagnosis is a requirement for eligibility): 
For tumors ≥6 mm by imaging: 
- 
Inferior petrosal sinus sampled (IPSS) ACTH central:plasma gradient ≥2 before 
CRH or ≥3 after CRH, OR if IPSS was not done then: 
- 
Positive ACTH and/or cortisol response to CRH/desmopressin or combined 
CRH-desmopressin stimulation plus high-dose (8 mg) dexamethasone 
suppression of plasma cortisol, ideally on more than one occasion, performed and 
interpreted according to internationally recognized standards of diagnosis 
- 
In the absence of IPSS and the combination of tests described, an individual 
might be eligible if CD was otherwise confirmed via adequate testing. Such cases 
must be discussed with and explicitly approved by the Medical Monitor, and the 
specific diagnostic criteria used to establish the diagnosis of CD must be 
documented. 
For tumors <6 mm or not visible by MRI: 
- 
IPSS with ACTH central:plasma gradient ≥2 before CRH or ≥3 after CRH 
- 
In the absence of IPSS, an individual might be eligible if CD was otherwise 
confirmed via adequate testing. Such cases must be discussed with and explicitly 
approved by the Medical Monitor, and the specific diagnostic criteria used to 
establish the diagnosis of CD must be documented. 
4. Regardless of the etiology of endogenous CS, subjects MUST have elevated mean 
24-hour UFC levels ≥1.5X ULN based on the normative range of the central lab assay 
and on a minimum of four measurements from adequately collected urine.  Urine will 
ideally be collected on sequential days.   
5. In addition to elevated mean UFC, presence of abnormal values from one of the 
following tests: 
• 
Abnormal DST: Elevated 8 AM serum cortisol ≥1.8 µg/dL (50 nmol/L) after 1 mg 
dexamethasone orally at 11 PM the evening prior (if not conducted already in the 
diagnostic workup of the subject within the previous 2 months before start of 
Screening Phase; in that case previous test results and details of conduct will need 
to be available by the Baseline Visit) 
• 
Elevated late night salivary cortisol concentrations (at least two measurements) 
>ULN  
NOTE: For subjects with estimated glomerular filtration rate (eGFR as determined by 
Modified Diet in Renal Disease MDRD equation) >40 and <60 mL/min/1.73 m2 in 
addition to meeting the UFC criteria, late night salivary cortisol test results 
(≥2 measurements) MUST also demonstrate evidence of CS.  
6. Previously irradiated subjects with CD or endogenous CS of other etiology will be 
allowed as long as the radiation treatment occurred > 4 years ago and subjects have not 
exhibited evidence for improvement in their underlying CD for 6 months prior to the 

Cortendo AB

to complete this study prior to surgery. For subjects who have already undergone surgery, 
a minimum of 6 weeks should have elapsed before the subject can be deemed a surgical 
failure.  Subjects who have undergone surgery should be stable post-surgery (i.e., no 
significant post-operative sequelae remain and the risk of such sequelae is considered 
negligible).

10. A female is eligible to enter and participate in the study if she is of:  
Non-child bearing potential (i.e. physiologically incapable of becoming pregnant, 
including any female who is post-menopausal or surgically sterile). Surgically sterile 
females are defined as those with a documented hysterectomy and/or bilateral 
oophorectomy or tubal ligation.  
Post-menopausal females are defined as being amenorrheic for greater than 1 year

INTRODUCTION  
1.1 Disease Background 
Endogenous Cushing´s syndrome (CS) is a rare, serious and potentially lethal endocrine 
disease caused by chronic elevated cortisol exposure to human organs. The incidence of 
CS has been estimated to be 2-3 cases per million per year [Lindholm 2001, Steffensen 
2010]. The prevalence of CS has been reported to be 30-60 cases per million [Dalton 
1974, Kreutzer 2009, Pivonello 2005, Sharma 2011]. Patients with incompletely 
controlled disease are seriously ill and have a 4 to 5-fold higher mortality rate than age-
and gender matched controls, mainly due to metabolic and cardiovascular complications 
[Lindholm 2001, Mancini 2004, Pivonello 2005]. 
Treatment options for CS include surgery, radiation therapy and medical treatment.  
Medical treatment is used to suppress excessive cortisol production or activity and 
ameliorate its clinical manifestations, prior to surgery, in patients awaiting the effects of 
radiation therapy [Nieman 2002], or in cases when surgery is delayed, contraindicated, or 
unsuccessful.  As such, normalization of 24-hour urinary free cortisol (UFC) and normal 
serum or plasma cortisol levels from a low-dose overnight dexamethasone suppression test 
(DST) are considered adequate markers of disease remission [Bochicchio 1995].  More 
recently, measurement of late night salivary cortisol levels is gaining clinical importance.  
Conversely, the persistence of high or only modestly reduced UFC levels argues for 
treatment failure.  
Ketoconazole (Nizoral®, comprised of two enantiomers: 2S,4R- and 2R,4S-ketoconazole) 
is an antifungal agent that, at higher dosages, reduces adrenal steroid production via 
inhibition of multiple steroidogenic enzymes, e.g. 11β-hydroxylase, 17α-hydroxylase and 
aldosterone synthase [Engelhardt 1991, Sonino 1987, Nizoral 2002]. One publication has 
reported a direct effect on ectopic adrenocorticotropic hormone (ACTH) secretion by 
ketoconazole. [Steen 1991]. Because of these properties of ketoconazole, it is a commonly 
used off-label drug for treatment of CS in the US and is approved for the treatment of CS 
in Europe and elsewhere [DeMartin 2006, Daniel 2015, Castinetti 2014, Nizoral 2013 
Product Insert, Ketoconazole 2014 HRA Assessment Report]. 
When patients are treated with ketoconazole, adrenal insufficiency is avoided by 
adjusting the dose to allow normal cortisol levels.  The most frequent adverse effects of 
ketoconazole are nausea, vomiting, abdominal pain and pruritus.  Abnormal liver 
function tests (LFTs), primarily of the hepatocellular type, can occur.  Rarely does severe 
hepatotoxicity occur.  Early markers for these side effects are elevations in serum alkaline 
phosphatase (AP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), 
and bilirubin, which are monitored at regular intervals during treatment [Ketoconazole 
2014 HRA Assessment Report, Nizoral 2013 Product Insert, Lake-Bakaar 1987; Lewis 
1984]. 
Cortendo AB is developing COR-003, also known as levoketoconazole, the 2S,4R 
enantiomer of ketoconazole, as an investigational new drug for the treatment of cortisol 
hypersecretion in CS.  It is hypothesized that COR-003 may prove to be both safer and 
more efficacious than ketoconazole.  

Cortendo AB 
 
Protocol COR-2012-01 
AMENDMENT 6

COR-003 has a significantly lower IC50 (50% inhibitory concentration) towards key 
enzymes in cortisol synthesis (11β -hydroxylase, IC50 = 150 nM; 17-α-hydroxylase 
[CYP17], IC50 = 48 nM) than the 2R,4S enantiomer of ketoconazole (IC50 = 680 nM 
and 1800 nM, respectively, thus potentially allowing a lower dose of drug to achieve the 
same efficacy [Rotstein 1992, unpublished results from Moulder Center for Drug 
Discovery Research, Temple University School of Pharmacy, 2012]. In rats, COR-003 
was more potent with respect to reducing corticosterone (the major glucocorticoid in 
rodents) than either the 2R, 4S-enantiomer or ketoconazole [Cortendo Report Number 
2002-02-21]. 
Although elevations in LFTs associated with ketoconazole [Daneshmend 1988, Kucers 
1997, Whitehouse 1994] are generally modest in nature and reversible following 
cessation of treatment, in rare cases (1 in 10,000 to 15,000 patients) severe hepatotoxicity 
may occur [Lewis 1984], and in extremely rare cases this adverse reaction may be 
irreversible and life-threatening. Preclinical data suggest that COR-003 may pose less 
risk to impair hepatic function than ketoconazole. 2S,4R-ketoconazole has 12-fold higher 
IC50 towards CYP7A (IC50 = 2.4 μM) than does 2R,4S-ketoconazole 
(IC50 = 0.195 μM) [Rotstein 1992]. CYP7A is the first and rate-limiting enzyme in the 
major (classical) liver pathway for production of bile acids, catalyzing 7α-hydroxylation 
of cholesterol and other oxysterols. Inhibition of this enzyme can lead to functional 
cholestasis and consequent accumulation of potentially toxic metabolites such as bilirubin 
and xenobiotics such as ketoconazole itself. 
Another property that suggests potentially improved safety of 2S,4R-ketoconazole 
compared to ketoconazole relates to the pharmacokinetics (PK) of the 2S,4R and 2R,4S 
enantiomers, which have been studied in humans after oral administration of 
ketoconazole or COR-003 [Gerber 2003, Schindler 2003, Schwartz 2008]. The 
enantiomers in ketoconazole are present in equal amounts, but following ketoconazole 
oral administration blood concentrations of the 2S,4R enantiomer exceed those of the 
2R,4S enantiomer by approximately 3-fold [Gerber 2003], suggesting preferred 
extraction of the 2R,4S enantiomer by the liver. Reduced hepatic exposure to the 2S,4R 
enantiomer (COR-003) may be of value in reducing the liver function abnormalities 
observed following administration of racemic ketoconazole. 
COR-003 has been previously administered to healthy volunteers and human subjects 
with Type 2 Diabetes Mellitus (T2DM).  Doses of COR-003 over the range of 200 mg to 
600 mg once daily (QD) for up to 14 days and 150 mg to 450 mg for up to 4 months were 
shown to be generally well tolerated in all of these studies, with an adverse effect profile 
similar to that of ketoconazole.  Please refer to the Investigator’s Brochure for a detailed 
description of all prior preclinical and clinical studies conducted with COR-003. 
1.2 Rationale for Study Design 
This study is the first and pivotal clinical trial investigating the safety and efficacy of 
COR-003 in subjects with endogenous CS.  This is an open label, single arm study with a 
Screening Phase, a Dose Titration Phase, a 6-month Maintenance Phase, and a 6-month 
Extended Evaluation Phase. An open label, single arm design was chosen, since a 

Cortendo AB 
 
Protocol COR-2012-01 
AMENDMENT 6 
Page 32 of 119 
CONFIDENTIAL 
 
concurrent placebo control as monotherapy was deemed unethical, and an approved drug 
to serve as active control (monotherapy) or as background therapy (adjunctive therapy) 
suitable for an international study population was unavailable. Pasireotide, which is 
approved in the EU and US, has a different mode of action at the tumor level and 
therefore an indication for Cushing’s disease (CD) only, and is an injectable with a 
different safety profile, including hyperglycemia, which would preclude blinding and 
confound evaluation of efficacy and safety signals. 
The chosen design has considered the reported experience treating CS patients with 
ketoconazole [Castinetti 2014].  Like ketoconazole, dosing of COR-003 needs to be 
individualized, since therapeutic need varies considerably among patients.  Response to 
therapy (i.e. normalization of UFC and clinical signs and symptoms) is equally variable 
and results in a wide range of effective doses, each tailored to an individual patient.  As 
such, the design of this study includes an initial Dose Titration Phase that will identify a 
tolerable and effective dose for each subject, which will then be administered during the 
subsequent Maintenance Phase of the study, intended to be without further dose 
increases. The Maintenance Phase was designed to demonstrate durability of the 
therapeutic response and, together with the Extended Evaluation Phase, provides 
long-term efficacy and safety data.

STUDY DESIGN 
This is a single arm, open label, dose titration study to assess efficacy, safety, tolerability, 
and PK of COR-003 in subjects with endogenous CS as illustrated in Figure 1.  The range 
of effective doses for COR-003 in this CS population will also be established.  Following 
an initial screening and washout period, as applicable, this study will be conducted in 
3 treatment phases as follows: 
• Dose Titration Phase:  approximately 2 to 21 weeks to achieve an effective and 
tolerable maximum dose (the Therapeutic Dose)—see Section 4.2 for details; 
• Maintenance Phase:  6 months of treatment at the Therapeutic Dose following 
the Dose Titration Phase; 
• Extended Evaluation Phase: 6 months of continued treatment after the 
Maintenance Phase. 
Figure 1 
Study Design 
 
 
Efficacy will be assessed by measuring UFC levels and other endpoints at the times 
indicated in the Time and Events Table (Appendix A). 
Blood samples for PK determination will be collected as described in Section 6.2.8.1.  
Note that the times indicated in the Time and Events Table (Appendix A) are indicative 
of potential collection times and do not apply to each subject. 
Safety data will be collected at the times indicated in the Time and Events Table and as 
described in Section 6.2.  Adequate medical coverage will be provided by the 
Investigator at all times during the course of the study (including nights, weekends and 
holidays) to ensure that prompt safety decisions can be made and appropriate medical 
interventions provided.  The Investigator should provide all subjects with instructions on 

Cortendo AB 
 
Protocol COR-2012-01 
AMENDMENT 6

how to access the medical staff regardless of day and time in order to obtain medical 
care.  An independent Data Safety Monitoring Board (DSMB) will review the safety of 
the drug throughout the study.  At a minimum, the DSMB membership will consist of an 
endocrinologist with expertise in the treatment and clinical investigation of CS; a 
gastroenterologist/hepatologist with expertise in the assessment of abnormal LFTs and 
hepatotoxicity during clinical study conduct; and an expert in the evaluation of QTc 
interval during clinical study conduct/clinical pharmacologist. The full extent of 
responsibilities by the DSMB is defined in its charter. 
Subjects completing the 6-month Maintenance Phase of the study with COR-003 will 
remain in the study for an additional 6 months for extended evaluations of safety and 
efficacy of COR-003 treatment (Extended Evaluation Phase).   
At the completion of the 6-month Extended Evaluation Phase, subjects may be eligible to 
enter an expanded access program and receive continued treatment with COR-003 in 
accordance with local regulations.  If the program is not available at their location, or 
they are not eligible to participate or do not wish to consent to the program, after 
completion of the Follow-Up Visit they will be promptly referred back to their 
endocrinologist (if not the Investigator) for further management according to the local 
standard of care, and based on their preceding medical history.  (Note: As subjects 
entering the expanded access program for COR-003 will not be discontinuing treatment 
with COR-003, they will not be required to complete the Follow-Up Visit for this study.) 
4.1 Screening Period 
After signing the informed consent, subjects will enter the Screening Period.  After 
performing initial Screening assessments, subjects on previous CS medical therapies or 
other prohibited medications must enter a washout period, as applicable (see Section 5) 
before completing all Screening assessments detailed in the Time and Events Table 
(Appendix A).  Baseline measurements will be obtained as part of the Screening 
assessments, after washout and completion of all initial Screening procedures. 
If a subject does not initially meet the eligibility requirements described in Section 5, 
they might be eligible to re-screen but only if their underlying condition has changed in 
the interim such that they are now likely to meet study eligibility criteria. Such 
re-screenings will be exceptional circumstances, and all re-screenings require prior 
permission of the study Medical Monitor before they begin. 
4.2 Dose Titration Phase 
After confirmation of eligibility at the Baseline Visit, including confirmation of increased 
UFC levels as per eligibility requirements, each subject will return to the investigational 
site to receive study medication and will begin dosing at dose level 1 (DL1) with an 
initial dose of 150 mg twice daily (BID), taken as one tablet in the morning and one tablet 
in the evening.  Decisions for subsequent dose increases will be based on an assessment 
of each subject’s UFC levels and safety data (i.e. tolerability of therapy) and will be made

by the Investigator.  The interval between dose adjustments will be approximately 
18 days (±4 days) 
4.2.1 Dose Titration and Adjustment Criteria 
COR-003 will be administered BID according to the titration scheme in Table 1 until one 
of the following criteria has been met:  
• Mean 24-hour UFC levels ≤ULN as established for the assay being used at a central 
laboratory 
• Highest protocol-specified dose reached 
• Highest tolerated dose reached (in the opinion of the Investigator)

*DL0, permitted for dose reductions, is a dose of 150 mg once daily administered in the evening, 
except on the day of the in-clinic procedures, when the dose should be administered in the clinic 
(see Section 8.2.1). 
All subjects will be asked to collect two adequate 24-hour urine specimens starting at 
Day 10 (±1 day) after the start of each dose level, ideally on two consecutive days.  The 
subjects are asked to bring or ship per courier service their two urine collections to the 
clinic, as soon as possible (approximately Day 12) for measurement of 24-hour UFC 
levels from each sample.  Urine volume and creatinine will be measured as markers of 
the adequacy of each collection (see Section 6.2.6.1 for definition).  Subjects will 
continue on their current dose of COR-003 until the UFC results have been obtained from 
the central laboratory (within approximately 2-4 days of shipment).  Based on their UFC 
results and tolerability, subjects will be asked to do one of the following:  
• Return to the clinic for scheduled assessments and receive the first dose of drug 
for the next Dose Titration interval; 
• Have a confirmatory UFC evaluation (e.g. two additional UFC measurements to 
determine if the Therapeutic Dose of COR-003 has been reached; 
Section 4.2.1.1); or 
• Enter the Maintenance Phase (if an alternative determination of Therapeutic Dose 
of COR-003 has been made; Section 4.2.1.1) as applicable.

4.2.1.1 Determination of the Effective and Tolerable Dose of COR-003 
(Therapeutic Dose) 
When a subject achieves normalized UFC results (≤ULN for UFC) from the mean of the 
first two adequately collected 24-hour urine samples, two additional 24-hour urine 
samples will be collected and returned to the clinic for submission to the central 
laboratory.  Subjects should be contacted as soon as the results from the first two 24-hour 
urine samples are received to ask them to begin the next two 24-hour urine collections.   
A Therapeutic Dose for a subject will be considered established when mean UFC levels 
(determined from a total of four adequate 24-hour urine collections) are ≤ULN of the 
assay, or the maximum dose allowed has been reached, or a clinically meaningful partial 
response and the maximal tolerated dose has been reached.  Once the Therapeutic Dose 
has been reached the subject can begin the Maintenance Phase of the study. 
Steps for Determination of Therapeutic Dose 
• If the mean value for the first two UFC test levels is ≤ULN of the assay of two 
adequate 24-hour urine collections, the subject should be notified immediately and 
asked to begin the next two 24-hour urine collections, for the purpose of confirming a 
biochemical response.  The two additional urine collections should be completed and 
returned to the clinic, as soon as practical (for example, if samples were provided to 
site on Day 12 following the dose escalation visit and results were received on Day 15, 
the subject should ideally begin collection the following day (Day 16) and return the 
two additional samples to the site immediately upon completion of collection (Day 
18).  The next visit for the subject should be scheduled to coincide with receipt of the 
results (Day 30 [±7 days]) and the mean of the four UFC test values is available to 
make the determination of whether or not the Therapeutic Dose has been achieved. 
• When confirmatory urine sample collection is required, in order to allow for adequate 
time for urine sample collection and analysis between visits, the subject should return 
no later than 37 days after the prior dose escalation visit for either the next dose 
escalation visit or start of the Maintenance Phase (based on the mean of the four UFC 
values) [NOTE: Always ensure that the subject has an adequate supply of COR-003 to 
cover the duration between visits.] 
• If the mean value of four adequate 24-hour urine collections is ≤ULN of the assay, the 
subject may enter the Maintenance Phase at the current dose level (i.e. Therapeutic 
Dose level) [Section 4.3].  The total duration of the Titration Phase should not be any 
longer than approximately 21 Weeks; assuming approximately 3 weeks of treatment 
for each dose level. 
• If the mean value of four adequate 24-hour urine collections is >ULN of the assay of 
four adequate 24-hour urine collections, the subject should proceed to the next Dose 
Level. 
Alternative Determination of Therapeutic Dose 
• If the subject has reached the highest allowed dose level and UFC levels remain 
>ULN of the assay for the mean of two adequate 24-hour urine collections, yet there is 

Cortendo AB 
 
Protocol COR-2012-01 
AMENDMENT 6 
Page 41 of 119 
CONFIDENTIAL 
 
a clinically meaningful partial response from Baseline, the subject may enter the 
Maintenance Phase at that dose level. 
• If the subject has reached the highest tolerated dose and UFC levels remain >ULN of 
the assay for the mean of two adequate 24-hour urine collections, yet there is a 
clinically meaningful partial response from Baseline, the subject may enter the 
Maintenance Phase at that dose level at the discretion of the Investigator. 
• If UFC is >ULN and LFTs are elevated, the Investigator may maintain the dose in the 
Dose Titration Phase in consultation with the Medical Monitor before a decision is 
made to progress to the next dose level or into Maintenance Phase.  
NOTE:  If UFC levels remain >ULN of the assay for the mean of two adequate 24-hour 
urine collections, and there is no clinically meaningful partial response from Baseline 
upon reaching the highest allowed dose or the highest tolerated dose, discontinuation 
should be considered. Consultation with the Medical Monitor is encouraged. 
4.2.1.2 Dose Titration to the Therapeutic Dose 
Subjects will continue the process of dose titration until the Therapeutic Dose has been 
reached (Section 4.2.1.1).  
• If UFC levels are >ULN of the assay for the mean of two adequate 24-hour urine 
collections, the dose should be increased to the next dose level, unless the highest 
tolerable dose or the highest protocol-specified dose has already been reached. 
• If UFC levels are >ULN of the assay for the mean of two adequate 24-hour urine 
collections, the subject should return no later than 22 days (18 days ± 4 days) after 
the prior dose escalation visit for the next dose escalation visit. 
Other factors that are to be considered during the Dose Titration Phase: 
• Subjects will have ECG evaluations at Baseline and within approximately 1 to 
2 hours after drug administration (i.e., at ~ Cmax) during the Dose Titration Phase at 
each dose level), monthly (at the Therapeutic Dose) during the Maintenance Phase 
and at each visit during the Extended Evaluation Phase using the Spaulding ECG 
device for collection of up to 5 minutes of continuous ECG (Section 6.2.4).  The dose 
of study medication will be reduced if the confirmed COR-003-related QTc interval 
persistently increases to >500 msec or >60 msec from Baseline. Please refer to 
Section 5.3.1 where guidance to the Investigator on the assessment of the prolonged 
QTc interval is provided in detail.  
• If the subject develops signs and/or symptoms of adrenal insufficiency (e.g., 
orthostatic hypotension, nausea, vomiting, abdominal pain), based on further 
investigation (see Section 6.3.3) and clinical judgment, the Investigator may 
temporarily stop dosing of the study medication to allow resolution of these 
symptoms.  In such cases, at the discretion of the Investigator, the dose will be 
reduced and restarted at a preceding dose level (see Section 6.2.4.2).  In the event that 
this observation is made at DL1, the subjects may receive a lower dose of 150 mg 
once daily (DL0) based on the medical discretion of the Investigator and agreement 
with the Sponsor.  Subjects may resume the Dose Titration scheme after a dose

reduction at the discretion of the Investigator and agreement with the Sponsor.  See 
Section 6.3.3 for details on assessment of signs and symptoms of adrenal 
insufficiency.  
4.2.2 Dose Titration Above 600 Mg Total Daily Dose 
COR-003 has only been dosed up to 600 mg/day in diabetic subjects. The safety in 
subjects at doses beyond 600 mg/day is unknown. For this reason, subjects that reach 
total daily doses of > 600 mg/day (i.e., doses of 750, 900, 1050, and 1200 mg/day) must 
be monitored more closely in order to ensure proper evaluation of the safety of doses at 
these levels.  In addition to the assessments that will be carried out during dose escalation 
for doses ≤600 mg/day, for each dose escalation beyond 600 mg/day, subjects will be 
asked to return for one additional safety evaluation 7 days (±3 days) after each dose 
escalation to include the following assessments:  AEs, vital signs, routine safety 
laboratory assessments (including LFTs), ECGs, and morning serum cortisol levels as 
outlined in Time and Events Table (Appendix A).  Subjects will be advised to contact the 
Investigator immediately in the event of developing adrenal insufficiency (see 
Section 6.3) or other AEs at any time. 
• Return 7 days (±3 days) after each dose level escalation visit for DL4 through DL7 for 
additional safety assessment (see Section 6.2.7.1);  
• Start the collection of two adequate 24-hour urine samples 10 days (±1 day) after the 
dose level escalation visit for DL4 through DL7 - provide containers to sites as soon as 
possible after completion (approximately 12 days after dose level escalation); 
• If the mean value for the first two adequate 24-hour urine collections is >ULN of the 
assay, the subject should return no later than 22 days (18 days ± 4 days) after the prior 
dose escalation visit for next dose escalation visit;  
• If the mean value for the first two adequate 24-hour urine collections is ≤ULN of the 
assay and additional UFC tests are needed to confirm the mean value of ≤ULN, the 
subject should be notified to collect an additional two 24-hour urine samples and 
return them to the site, as soon as possible after completion (see timing details in 
Section 4.2.1.1).  
 
The results of relevant assessments should be available promptly in order for the 
Investigator to make decisions for the safety of the subject.  Reports of Serious Adverse 
Events (SAEs) experienced at these higher doses will be shared with all Investigators 
regularly during the study.  
4.3 Maintenance Phase 
By convention, the very first visit during the Maintenance Phase will be called “Month 1” 
and will take place on the first day of Month 1 of the Maintenance Phase. After the 
Month 1 visit, subjects will be asked to return to the clinic monthly (every 30 ± 7 days) 
for approximately 6 months for assessment of efficacy and safety (as outlined in the Time 
and Events Table [Appendix A]).   

Cortendo AB 
 
Protocol COR-2012-01 
AMENDMENT 6 
Page 43 of 119 
CONFIDENTIAL 
 
During the Maintenance Phase, doses may not be increased to maintain UFC levels at or 
below ULN of the assay unless it is confirmed that a dose increase is deemed medically 
necessary, based on a totality of evidence including other disease markers or symptoms, 
at the discretion of the Investigator after discussion with the Medical Monitor.  The 
reason for this restriction is that some variability in mean UFC levels from two urine 
collections is expected, and such variability in and of itself is not considered a sufficient 
reason for further dosage adjustment. If it is deemed medically necessary, prior to 
increasing the dose during the Maintenance Phase, two additional adequate 24-hour urine 
collections should be obtained within 2 weeks of the first UFC samples to provide a total 
of four UFC samples for analysis.  If confirmed hypercortisolemia is present, the COR-
003 dose may be increased by 150-mg increments as medically indicated up to the 
maximally allowed dose of 1200 mg/day, and the subject may stay in the study through 
completion. 
During the Maintenance Phase the COR-003 dose may also be reduced temporarily or 
permanently for safety reasons, including but not limited to LFT elevation (see 
Section 5.3.2, instructions for re-challenge), QTc prolongation (Section 5.3.1) and 
adrenal insufficiency (Section 6.3.3). If medically indicated, the dose should be resumed 
at the individual’s Therapeutic Dose.  All dose adjustments during the Maintenance 
Phase must be documented.  
4.4 Transition from Maintenance Phase to Extended Evaluation Phase 
Prior to the End of Maintenance Phase Visit, four complete 24-hour urine collections will 
be obtained and subjects may enter the Extended Evaluation Phase (Section 4.5).   
4.4.1 Exclusion of Treatment Effect Due to Delayed Onset of Radiation 
Therapy 
Previously irradiated subjects must stop treatment with COR-003 for at least 
2 weeks after the end of the 6-month Maintenance Phase (End of Maintenance 
Phase Visit) and provide four complete 24-hour urine collections for UFC 
measurements collected at least 14 days following the End of Maintenance Phase 
Visit.  If the 24-hour UFC results indicate that UFC levels are elevated, the subject may 
subsequently restart therapy and continue into the Extended Evaluation Phase, at the 
discretion of the Investigator (Section 4.5).  [NOTE: Subjects restarting therapy should 
initiate therapy as soon as the need is identified and should return for their next in-clinic 
visit (M9) for study assessments and resupply of study medication 90 days (±14 days) 
from the End of Maintenance Visit.] 
4.5 Extended Evaluation Phase 
The end of the Maintenance Phase visit will be the start of the Extended Evaluation 
Phase. In the 6-month Extended Evaluation Phase, subjects will return to the clinical site 
every 3 months (every 90 days ± 14 days) for assessments, (i.e., at the end of Months 9 
and 12), and will have safety and efficacy evaluations as indicated in the Time and 
Events Table (Appendix A).   

Cortendo AB 
 
Protocol COR-2012-01

CONFIDENTIAL 
 
After completion of treatment in this study, if subjects do not extend treatment through 
the expanded access program (Section 4.7), they will return for a Follow-Up Visit as 
indicated in the Time and Events Table (Appendix A).  The Follow-Up Visit should be a 
minimum of 2 weeks (14 days) and no longer than 30 days following the completion of 
treatment. [NOTE: The Follow-Up Visit is not required for subjects continuing into 
expanded access treatment (see Section 4.7)]. 
4.6 Stopping Criteria 
Dosing with the study medication will cease due to any of the following observations: 
• Intolerability to the study medication based on the subjects’ signs or symptoms in 
accordance with the Investigator’s medical judgment 
• Lack of any clinically relevant response at the maximally tolerated dose, in the 
opinion of the Investigator 
• QTc prolongation as specified in Section 5.3.1 at 150 mg/day 
• LFT abnormalities as specified in Section 5.3.2 
• Adrenal insufficiency at the lowest dose of COR-003 (150 mg daily)—See also 
Section 6.3.3 for more details 
• Any withdrawal criteria specified in Section 5.3. 
 
Subjects who are withdrawn early will complete the Follow-Up Visit (see Appendix A) 
and provide two adequate 24-hour urine collections within approximately 2 weeks of 
termination of treatment with COR-003. 
The cause for withdrawal will be documented and appropriately captured in the database. 
Withdrawn subjects, due to any of the above criteria, must receive appropriate follow-up 
medical care. The Investigator will explain all other treatment options available to them 
in their country of residence and subjects will be promptly referred back to their 
endocrinologist (if not the Investigator) for further management according to the local 
standard of care and based on their preceding medical history.   
4.7 Optional Expanded Access Program 
An expanded access program (COR-2015-EAP) will be made available, as local 
regulations allow, to sites participating in this study.  Subject interest and eligibility for 
participating in the expanded access program will be evaluated at the M9 visit, including 
the informed consent process.  If eligible, they will begin participation in the 
COR-2015-EAP program upon completion of the M12 visit.  Subjects continuing into 
expanded access program will NOT be required to complete the Follow-Up Visit for 
COR-2012-01.  
If a subject completing COR-2012-01 at a site that does not have regulatory approval to 
provide access to COR-003 under the expanded access program wishes to continue 
COR-003 treatment after completing this study, Cortendo will make a reasonable effort 
to provide continued access to the medication through another access option that meets 
all applicable local and national regulatory requirements.

In the event that continued access to COR-003 is anticipated but delayed for any reason, 
and dosing with COR-003 will be interrupted for more than 2 weeks, the Follow-Up Visit 
should occur according to the Time and Event Schedule (see Appendix A).

SUBJECT SELECTION AND WITHDRAWAL CRITERIA 
Cortendo will review each subject’s enrollment criteria to ensure that subjects meet the 
eligibility criteria. 
5.1 Inclusion Criteria 
Subjects eligible for enrollment in the study must meet all of the following criteria: 
1. Male or female ≥18 years of age 
2. Able to provide written informed consent prior to any study procedures being 
performed; eligible subjects must be able to understand the informed consent form 
prior to inclusion into the study. 
3. Confirmed diagnosis of newly diagnosed, persistent or recurrent CD or endogenous 
CS of other etiology if subjects are not candidates for surgery or radiotherapy within 
the 18 months after enrollment. 
Previous medical records will be collected and used to support the diagnosis of CD or 
endogenous CS of other etiology, including the following etiologies:   
• Ectopic ACTH secretion, i.e. ACTH not of pituitary origin 
• Ectopic corticotropin-releasing hormone (CRH) secretion 
• Adrenal-dependent CS (i.e. adrenal adenoma (NOT carcinoma), adrenal 
hyperplasia, etc.) 
• Etiology unknown 
 
In the absence of pathological or post-surgical confirmation of the diagnosis of CD 
(i.e. documented adrenal insufficiency post-adenomectomy or hypophysectomy, 
which will be considered diagnostic). The following historical evidence will be 
considered satisfactory to establish the diagnosis of CD: 
• Plasma corticotropin (ACTH) level >20 pg/mL (4.5 pmol/L) or greater 
(Note: ACTH ≥5 pg/mL (1.1 pmol/L) and ≤20 pg/mL will generally suffice 
only if accompanied by either a positive CRH stimulation test or DST or 
combined CRH-DST) PLUS one of the diagnostic strategies described below

5.3 Withdrawal Criteria 
Subjects have the right to discontinue participation in the study at any time. Reasons for 
withdrawal during the study may include, but are not limited, to the following: 
• Withdrawal of informed consent. 
• Safety reasons, as stipulated in Sections 5.3.1 and 5.3.2, either at the discretion of 
the Investigator or at the subject’s request (see also Section 4.6, Stopping 
Criteria). 
• Protocol violations at the discretion of the Sponsor. 
• Concomitant therapy that could interfere with the results of the study (the 
Investigator will report all such information on the case report forms [CRFs] and 
decide, in accordance with the Sponsor, whether the subject is to be withdrawn).  
All premature discontinuations and their causes must be carefully documented by the 
Investigator on the CRF, and, if need be, on the AE page.   
If, for any reason, a subject is withdrawn before completing the study, the reason for 
termination will be entered in the CRF.  All data gathered on the subject prior to 
termination will be made available to the Sponsor.  All withdrawn subjects will be asked 
to report to the clinic for a Follow-Up Visit at approximately 2 weeks after receiving their 
last dose of the study medication.  All assessments at the Follow-Up Visit are listed in the 
Time and Events Table (Appendix A). All AEs will be followed until resolution or at a 
minimum of 30 days after the last dose of the study medication.   
5.3.1 Withdrawal due QTc Interval Prolongation 
If a persistent and confirmed COR-003-related QTc interval prolongation >500 msec or a 
change from Baseline of >60 msec as defined below is identified, an attempt should be 
made to manage such QTc prolongations by dose reduction. If a persistent and confirmed 
COR-003-related QTc interval prolongation >500 msec or a change from Baseline of 
>60 msec is observed at the lowest COR-003 dose (150 mg/day), administration of the 
study drug will cease and the subject will be withdrawn.   
In order to decide whether a QTc prolongation is persistent and confirmed to be related to 
COR-003, QTc will be evaluated using the Spaulding ECG device or a local ECG device 
with central reading of the ECG by Spaulding. The Investigator should consider 
alternative possibilities as causative or contributory to QTc prolongation prior to 
discontinuation of COR-003, including concomitant medications that may result in 
prolongation of the QTc interval either directly or through interference with the 
metabolism of COR-003, recent food ingestion (temporary QTc elevation), and 
electrolyte abnormalities (particularly serum calcium, magnesium and potassium). 
Interfering concomitant medications with QT prolongation potential are contraindicated 
in co-administration with COR-003 and must be stopped (Section 10.2). Please also see 
Section 6.2.4.1 for guidance on the assessment of QTc interval prolongation. Regardless 
of seriousness or causality, instances of persistent QTc prolongation should be reported to 
the Sponsor’s designated Pharmacovigilance group within 24 hours from the time the 

Cortendo AB 
 
Protocol COR-2012-01 
AMENDMENT 6 
Page 51 of 119 
CONFIDENTIAL 
 
persistent prolongation has been confirmed, in the same manner as SAEs (see 
Section 13.2.2).  
If persistent and confirmed QTc prolongation, as defined above, is observed, an 
additional PK sample should be collected as close to the time of the event as possible, 
ideally within several hours of dosing. 
5.3.2 Withdrawal and/or Re-Challenge due to Liver Function Tests (LFTs) 
The recommendations within the Food and Drug Administration (FDA) Guidance on 
Drug-Induced Liver Injury: Premarketing Clinical Evaluation (May 2009) have been 
adopted for use in this protocol to address abnormal LFTs.  LFTs will be measured at 
every study visit. In addition, LFTs will be measured immediately if subjects develop 
signs and symptoms suggestive of hepatic dysfunction (any of the following: nausea, 
anorexia, fever, fatigue, right upper quadrant discomfort, pruritus, dark urine or acholic 
stool).  Nausea, anorexia, and fatigue are non-specific symptoms and may be caused 
by hypocortisolemia; however, appropriate medical evaluation of such symptoms 
must include assessment of LFTs.  Other testing including laboratory assessments to 
assess causality (such as, hepatitis [A, B, C, E], autoimmunity), imaging and consultation 
with a liver specialist should be obtained prior to a planned withdrawal of the subject due 
to elevated LFTs.  Appropriate medical evaluations and interventions should be 
implemented based on the clinical presentation of the subject, including appropriate 
diagnostic imaging procedures.  All such medical interventions will be recorded in the 
CRF. While LFTs may be assayed at a local lab for immediate medical intervention, 
simultaneous samples must be sent to the central laboratory to ensure consistency of 
assay and interpretation. 
Subjects withdrawn due to LFT abnormalities must be followed until LFT normalization 
or until near Baseline values and stable.  Subjects not withdrawn from the study may be 
re-challenged after resolution of LFT abnormalities, at the discretion of the Investigator 
AND with approval by the Cortendo Medical Monitor.  
In agreement with FDA Guidance of 2009, discontinuation of therapy should be 
considered if: 
• ALT or AST >8X ULN 
• ALT or AST rises to >5X ULN in <4 weeks or persists for >2 weeks 
• ALT or AST >3X ULN and TBN >2X ULN or International Normalized Ratio 
(INR) >1.5 not explained by any other cause such as viral hepatitis, and without 
evidence of cholestasis  
• ALT or AST >3X ULN with new onset of or worsening of fatigue, nausea, 
vomiting, fever, rash or eosinophilia, in the absence of other evident cause 
• Signs and /or symptoms suggestive of hepatic dysfunction (any of the following: 
nausea, anorexia, fever, fatigue, right upper quadrant discomfort, pruritus, dark 
urine or acholic stool) coupled with ALT and/or AST >3X ULN and/or AP >2X 
ULN, and/or TBN >2X ULN in the absence of evidence for obstruction or Gilbert

syndrome. An ultrasound evaluation of the gallbladder and bile duct should be 
conducted to exclude cholestasis as the cause for elevated AP and/or TBN. 
  
Subjects with ALT and/or AST >3X ULN or AP >2X ULN (in the absence of evidence 
for cholestasis) or TBN >2X ULN (in the absence of evidence for cholestasis and except 
for subjects enrolled with presumed Gilbert’s syndrome) at any visit will undergo serial 
repeat LFT and INR evaluations. The first repeat LFT should occur as soon as possible 
after initial determination to confirm the observation and thereafter at 3 to 4 day intervals 
or as the clinical situation dictates.  Appropriate medical evaluations and interventions 
should be implemented based on the clinical presentation of the subject.   
If the LFTs return towards Baseline, serial measurements can be discontinued at the 
discretion of the Investigator, and the subject will continue for the remainder of the trial.  
If therapy has been interrupted and LFTs have normalized, subjects may be re-challenged 
at the discretion of the Investigator AND with approval by the Cortendo Medical 
Monitor.  If LFT elevations persist beyond 4 weeks after interruption of therapy or 
demonstrate a trend of worsening following interruption, then the subject should be 
withdrawn from the study.  The subject will continue to be followed after withdrawal 
until resolution or normalization of the laboratory abnormality that resulted in the 
withdrawal. 
If on serial measurements and in the absence of clinical signs or symptoms, the ALT 
and/or AST continue to rise (but TBN do not exceed the cut-offs for study drug 
cessation/early termination), subjects will continue on study drug and protocol unless the 
ALT and/or AST levels are >8X or are persistently higher than 5X ULN. If the ALT 
and/or AST levels exceed these levels, the subject should stop taking the study 
medication immediately.

STUDY ASSESSMENTS AND PROCEDURES 
The exact timings of each assessment are provided in the Time and Events Table 
(Appendix A).  Detailed procedures are provided in the Study Procedures Manual.  The 
study is being conducted and reported in accordance with the guidelines presented in 
Appendix D and Appendix E.  Any changes to the study design are managed in 
accordance with Appendix F. 
In addition to the protocol-specified procedures, at any time during the study 
appropriate medical evaluations and safety interventions should be implemented, as 
necessary, based on the clinical presentation of the subject according to standard of 
care, at the discretion of the Investigator.  Changes to the medical conditions, 
history and medications and all other medical interventions will be documented in 
the CRFs as unscheduled visits. 

Cortendo AB 
 
Protocol COR-2012-01

The study will consist of the following phases with approximate timings: 
• Screening Phase (up to approximately 12 weeks’ duration, prior to first dose) 
• Dose Titration Phase (approximately 2-21 weeks’ duration) 
• Maintenance Phase (6 months’ duration) 
• Extended Evaluation Phase (6 months’ duration) 
After signing the informed consent, subjects will enter the Screening Phase.  After 
performing the initial Screening assessments, subjects on previous CS therapies must 
enter a washout period, as applicable (see Section 5.1) before completing all Screening 
assessments detailed in the Time and Events Table (Appendix A).  Baseline evaluations 
will be obtained as part of the Screening assessments and should be conducted AFTER 
completion of all initial Screening procedures and after subjects have undergone a 
sufficient washout period from previous CS therapies (see Section 5.1), if applicable. 
Results from the Baseline assessments are necessary in order to determine if the subject 
remains eligible for participation in the study.  Please see the Study Procedure Manual 
(SPM) for details on urine collections.  
All subjects must meet all eligibility criteria prior to the first dosing.   
A screen failure subject is one from whom a signed informed consent is obtained but who 
has not started on treatment and failed to meet some or all eligibility criteria at Baseline.  
With approval by the Sponsor Medical Monitor, subjects may have repeated assessments 
of laboratory values for screening purposes to confirm eligibility if the condition limiting 
their participation has changed and is no longer limiting.  Re-screening is allowed for 
subjects with changes in their medical condition that alters their potential to meet the 
eligibility criteria. All re-screenings are considered exceptional and require prior 
permission of the Medical Monitor. 
6.1 Demographic/Medical History Assessments 
The following demographic parameters will be captured at Screening:   
• Date of birth 
• Gender 
• Race and ethnicity 
Medical and medication history will be assessed and collected as related to the Eligibility 
Criteria in Section 5.1 and will include the following, as available: 
• An effort will be made to collect the following information for documentation of 
medical history as part of this study: 
 Documentation of diagnosis of CS, including but not limited to 
evaluations for CS for the previous 6 months, e.g., levels of UFC, late 
night salivary and/or serum cortisol, DST results, IPSS results and 
diagnostic imaging results

 Documentation of associated metabolic complications (e.g., diabetes, 
hypertension, osteoporosis, and reproductive dysfunction) 
 Documentation of prior management of CS for the previous 3 months, 
including medications (capturing doses, duration of treatment, time of 
discontinuation and reason for discontinuation of medication) and any 
surgical or radiation therapies 
• Available clinical laboratory data for the previous 3 months; specifically: LFTs 
(ALT, AST, AP, direct and TBN), HbA1c, fasting serum glucose, OGTT, serum 
lipid panel (LDL-C, HDL-C, total cholesterol, triglycerides), CRP, urinary 
albumin/creatinine ratio, testosterone and IGF-1 concentrations 
• Available blood pressure data for the previous 3 months 
• Medication history (all medications, including any non-prescription medications, 
other than those to treat CS specifically) taken within 3 months prior to Screening 
with particular attention to blood pressure, anti-diabetic and cholesterol lowering 
drugs 
• History of drug and alcohol use. 
6.2 Safety and Efficacy Assessments 
6.2.1 Physical Examination and Assessment of Clinical Signs and Symptoms 
of CS 
Full physical examinations will be performed by a physician at the times indicated in the 
Time and Events Table (Appendix A).  The physical examinations will be inclusive of all 
body systems, and should include height (cm) and weight (kg). Abdominal girth will be 
measured in triplicate at the times indicated in the Time and Events Table and as 
described in the SPM.  BMI will be calculated based on data entered into the CRF during 
that visit.   
The examining physician will be asked to complete a questionnaire related to the 
assessment of Clinical Signs and Symptoms of CS (see Appendix M).  The results will be 
used to quantify changes in Clinical Signs and Symptoms of CS.  Details regarding these 
assessments will be provided in the SPM.  
6.2.2 Standard Photographs 
Standard photographs will be taken for consenting subjects to document visible signs of 
hypercortisolism at the times indicated in the Time and Events Table (Appendix A) as 
described in the COR-2012-01 Photography Manual.   
6.2.3 Vital Signs 
Vital sign measurements will include temperature, sitting SBP, DBP and heart rate (HR) 
at Baseline and at each visit throughout the study (see Time and Events Table in 
Appendix A).   
For proper measurement of blood pressure, the following procedures should be followed: 

Cortendo AB 
 
Protocol COR-2012-01 
AMENDMENT 6 
Page 55 of 119 
CONFIDENTIAL 
 
• Use of an appropriately sized cuff for the size of the subject’s arm circumference 
should be utilized to minimize inaccurate readings.  The sites may use available 
cuffs on site for these measurements. 
• No smoking or exercise for at least 30 minutes before a blood pressure 
measurement. 
• Subjects should sit in a chair with a back support and the arm supported at heart 
level with feet flat on the floor. The subject should void prior to the measurement. 
• Blood pressure measurements will be measured in triplicate over a minimum of 
approximately 10 minutes after the subject has rested in a sitting position for at 
least 10 minutes.  The three measurements will each be recorded in the CRF and a 
mean value for that visit will be calculated for reporting. 
Vital sign measurements must be repeated if clinically significant or machine/equipment 
errors occur.  Out of range blood pressure or HR measurements will be repeated at the 
Investigator’s discretion.  Any confirmed, clinically significant change from Baseline 
vital sign measurements must be recorded as AEs. 
Guidelines for classification for blood pressure levels and recommendations for follow-
up are provided in Appendix I. 
6.2.4 12-Lead Electrocardiograms (ECG) 
Male patients with CS have been reported to have prolongation of the QT interval 
[Giraldi 2011].  Thus, the inclusion criteria have allowed for this possibility and both 
males and females with QTc prolongation will be allowed into the study with Baseline 
QTc ≤470 msec.  
QTc interval is highly variable during the course of a day. Food intake can increase QTc 
intervals. Nausea, vomiting, upset stomach, and dizziness can also cause prolongation in 
the QTc interval, as well as electrolyte abnormalities (low serum magnesium, calcium 
and potassium levels).  
Many drugs can prolong the QTc interval directly, or in the case of COR-003, through 
interference with the metabolism of COR-003 causing levels of the drug to increase, thus 
resulting in a prolongation of the QTc. 
In this study, ECG monitoring is being performed at the designated times (as in the Time 
and Events Table in Appendix A), ideally using the Spaulding ECG device continuously 
for a maximum of 5 minutes.  
It will be upon this integrated summary result that QTc prolongation will initially be 
identified. The integrated summary of the ECG assessments (including arrhythmia 
analysis) will be done centrally after electronic transmission of the data, along with real-
time results provided to the Investigator.  
NOTE:  ECGs during the Screening Visit (single ECGs) are not required to be performed 
using the Spaulding ECG device. The Spaulding ECG device should be used at the 
Baseline Visit and for all subsequent assessments during the study.  In the event that the 

Cortendo AB 
 
Protocol COR-2012-01 
AMENDMENT 6 
Page 56 of 119 
CONFIDENTIAL 
 
Spaulding ECG device is not available, a local ECG may be performed (following the 
below guidance) and transmitted to Spaulding via a paper printout of the recording. 
ECGs will be obtained within approximately 1 to 2 hours after drug administration (i.e., 
at approximately Cmax of COR-003). ECGs will be obtained after the subject has rested 
in a supine position for at least 5 minutes, and should be conducted after the subject has 
not eaten for at least 2 hours. A small snack will be allowed for diabetic subjects and 
subjects who are intolerant of fasting since food intake can prolong QTc intervals. Food 
intake has to be recorded in the CRF.  The recording from the continuous ECG 
(maximum of 5 minutes) reading with the Spaulding device will be uploaded 
electronically to a computer and subsequently transmitted over the internet for centralized 
analysis and archiving.  The system will provide automated measurements of HR, 
respiratory rate (RR), PR, QRS, QT, QTcF and QTcB and ECG diagnostic statements to 
the investigative site within a short time following the completion and uploading of the 
recording.  A central reader cardiologist, not involved in the conduct of the study, will 
subsequently evaluate the ECGs.  It is imperative that the transmission of all ECGs to 
the central reader takes place as soon as possible after the completion of the test to 
allow for the proper medical evaluation of the subject should QTc prolongations 
occur.  
6.2.4.1 Prolongation of QTc Interval > 500 Msec or > 60 Msec Above 
Baseline 
The potential risk of protracted, drug-induced prolongation of the QTc interval is the 
development of an arrhythmia called Torsade de Pointes. The development of Torsade de 
Pointes in the face of QTc interval prolongation is rare, and appears to occur primarily 
when the QTc interval is particularly prolonged and generally at least >500 msec or 
>60 msec above Baseline.  
Subjects with prolonged QTc intervals >500 msec or >60 msec increase over the QTc 
interval at the Baseline Visit based on the assessment ideally using the Spaulding ECG 
device or local ECG must be medically observed until the QTc has returned to a value 
≤500 msec or ≤60 msec change from Baseline.  
The following need to be considered in cases of QTc prolongation: 
• If the integrated ECG reading demonstrates a QTc prolongation >60 msec from 
Baseline or an absolute QTc >500 msec, the subject should be questioned about 
recent ingestion of food within the preceding 2 hours. If the subject has eaten, a 
repeat ECG evaluation should be conducted following a proper 2-hour fast.  
• The subject should also be questioned about the use of any other medications that 
may have increased QTc interval, either directly because of their direct effect on the 
QTc interval or indirectly as a result of a drug interaction that may have increased the 
concentrations of COR-003. If such a drug is identified, it should be stopped 
immediately.  

Cortendo AB 
 
Protocol COR-2012-01

• The subject should be evaluated for symptoms of nausea or recent vomiting prior to 
the ECG assessment, lightheadedness or other symptoms that may influence the QTc 
interval. In such cases, the ECG evaluation should be conducted once the subject's 
symptoms have abated. COR-003 dosing may have to be withheld if the symptoms 
are protracted and the QTc interval prolongation remains evident. The Investigator 
should ensure that the symptoms as well as the ECG results are not due to a 
cardiovascular event, such as a myocardial infarction. 
• If the subject has not eaten, has no confounding medical symptoms/events, does not 
have a concomitant medication that may be increasing the QTc interval, and there are 
no other significant abnormalities on the ECG warranting immediate medical 
intervention, a repeat ECG evaluation should be undertaken within approximately 
30 minutes of the observed ECG prolongation or as soon as it is practical.  
• If the repeat ECG evaluation continues to demonstrate QTc prolongation >60 msec 
above Baseline or an absolute value of >500 msec, a blood sample should be obtained 
from the subject for evaluation of electrolyte abnormalities, including potassium, 
magnesium and calcium concentrations in addition to routine electrolytes and for a 
PK evaluation. If electrolyte abnormalities are identified, these should be corrected 
before re-evaluation of the ECG. COR-003 may be temporarily withheld until 
electrolytes can be normalized. 
If electrolytes are normal and no other cause can be identified to account for the absolute 
QTc interval >500 msec (or >60 msec above Baseline), and the ECG evaluation on repeat 
determination demonstrated persistent QTc prolongation, causal relationship to COR-003 
should be assumed and COR-003 should be withheld. The ECG should be monitored per 
discretion of the Investigator until resolution of the QTc prolongation.  In all cases, 
abnormal morphology of the ECG (especially T wave changes), if present, will be 
recorded in the CRF.  
If the subject is on the lowest possible dose of COR-003 (150 mg/day) and has persistent 
and COR-003-related QTc interval prolongation >500 msec or a change from Baseline of 
>60 msec, administration of the study drug will cease permanently and the subject will be 
withdrawn.  
At higher doses, an attempt should be made to manage persistent QTc prolongations that 
are deemed to be related to COR-003 by resuming treatment at a lower dose after 
resolution of QTc prolongation as described below.  If persistent and confirmed QTc 
prolongation is observed, an additional PK sample should be collected as close to the 
time of the event as possible, ideally within several hours of dosing. 
Persistent and confirmed QTc prolongation are defined as follows: 
• Persistence:  The 12-lead ECG should be repeated within 30 minutes of the first 
ECG revealing a QTc prolongation to confirm the persistent reading. 
• Confirmation:  The Investigator should consider alternative possibilities as 
causative or contributory to the QTc prolongation prior to discontinuation of the 

Cortendo AB 
 
Protocol COR-2012-01 
AMENDMENT 6 
Page 58 of 119 
CONFIDENTIAL 
 
study drug and/or study withdrawal.  Such contributing factors include 
nausea/vomiting, concomitant medications that may result in prolongation of the 
QTc interval either directly or through interference with the metabolism of 
COR-003, recent food ingestion (temporary QTc elevation), and electrolyte 
abnormalities (particularly serum calcium, magnesium and potassium).  
Supplementing potassium to raise serum potassium into the high-normal range 
can shorten the QTc interval in many cases.  Interfering concomitant medications 
with this potential are contraindicated in co-administration with the study drug 
and must be stopped (Appendix J). 
Regardless of seriousness or causality, instances of persistent QTc prolongation should be 
reported to the Sponsor’s designated Pharmacovigilance group as an AESI within 
24 hours from the time the persistent prolongation has been confirmed, similar to the 
reporting for SAEs (see Section 13.7). 
6.2.4.2 Resuming Treatment After Resolution of QTc Prolongation 
COR-003 at a lower dose can be restarted after a washout period of 2 days and resolution 
of the QTc prolongation (absolute QTc interval ≤500 msec or is ≤60 msec above 
Baseline). After restart, ECG evaluation should occur within 1 to 2 hours of resumption 
of dosing and be continued according to the visit schedule for increased safety 
monitoring.   
Abnormal morphology of the ECG (especially T wave changes), if present, will be 
recorded in the CRF.  If the absolute QTc interval remains ≤500 msec, or remains 
≤60 msec below the Baseline value, administration of COR-003 may be continued at the 
discretion of the Investigator and with approval by the Cortendo Medical Monitor. 
If persistent QTc prolongation deemed related to COR-003 is observed after 
reintroduction at a lower dose, COR-003 should be permanently discontinued (see 
Withdrawal criteria in Section 5.3.1), an additional PK sample should be collected as 
close to the time of the event as possible and repeat ECG evaluation should occur until 
QTc interval remains ≤500 msec, or ≤60 msec below the Baseline value. 
6.2.5 Clinical Laboratory Tests 
Samples for clinical laboratory testing will be collected at the times indicated in the Time 
and Events Table (Appendix A).  A complete list of all the analytes, including an entire 
battery of LFTs, is provided in Appendix B.  In addition to biochemistry, hematology and 
urinalysis, laboratory parameters will also include the following: serum cortisol, ACTH, 
FSH (women only), TSH, free T4, serum free and total testosterone, IGF-1, coagulation 
parameters (prothrombin time [PT], partial thromboplastin time [PTT], INR), 
triglycerides, serum lipid panel, HbA1c, CRP, and spot urine for albumin/creatinine ratio 
to determine microalbuminuria.  Screening safety laboratory tests will also include the 
following:  HIV, as well as antibody for hepatitis B and C. All testing will be conducted 
in a fasting state and in the morning unless stated differently in the Time and Events 
Table (Appendix A).   

Cortendo AB 
 
Protocol COR-2012-01 
AMENDMENT 6 
Page 59 of 119 
CONFIDENTIAL 
 
TSH and free T4 will be measured during the Screening Phase, DL4 during the Dose 
Titration Phase, then every 2 months during the Maintenance Phase and both Extended 
Evaluation Phase visits.  If subjects achieve their maximum COR-003 dose prior to DL4, 
their TSH and free T4 levels must be measured at Month 1 of the Maintenance Phase 
(time = 0), every 2 months during the Maintenance Phase and every 3 months during the 
Extended Evaluation Phase. 
6.2.5.1 Pregnancy 
Regardless of post-menopausal status, all female participants must have a negative 
pregnancy test at screening and at study visits indicated in the Time and Events Table 
(Appendix A).  A urine βhCG will be performed at the first Screening visit and all other 
subsequent visits.  Results of the test must be available before dosing can begin. 
Post-menopausal females will be defined as having amenorrhea for a minimum of 
24 consecutive months and an elevated FSH level during the Screening Phase.   
Women of child-bearing potential must agree to use an effective form of contraception 
for up to 2 weeks after study completion.  Acceptable methods include the following: 
• Male partner is sterile prior to female subject entry into the study, and 
this male partner is the sole partner for that subject; or  
• Implants of levonorgestrol inserted for at least 1 month prior to the study 
medication administration but not beyond the third successive year 
following insertion; or  
• Oral contraceptive (combined or progestogen only) administered for at 
least one monthly cycle prior to study medication administration; or  
• Double barrier method: condom or occlusive cap (diaphragm or 
cervical/vault caps) plus spermicidal agent 
(foam/gel/film/cream/suppository); or  
• An intrauterine device (IUD); or  
• Estrogenic vaginal ring; or  
• Percutaneous contraceptive patches; or 
• If medical contraceptives and barrier methods are not feasible for medical or 
religious reasons, an assurance of abstinence will be deemed an acceptable 
form of contraception for as long as the subject remains abstinent. 
Fertile men must agree to use a double barrier method of contraception (condom plus 
spermicide or diaphragm plus spermicide) while participating in the study and for 
2 weeks after the last dose of study drug OR, the male subject or his female partner must 
be surgically sterile (e.g. vasectomy, tubal ligation) or the female partner must be post-
menopausal. 
Reports of pregnancies in female subjects (or in female partners of male subjects) will be 
collected after the start of dosing and until the Follow-Up Visit.  Female subjects found to 
be pregnant will be withdrawn from the study.

6.2.5.2 Action to be Taken if Pregnancy Occurs 
The Investigator will collect pregnancy information on any female subject or partner of a 
male subject who becomes pregnant while participating in this study.  The Investigator 
will record pregnancy information on the appropriate form and submit it to the Sponsor 
within 24 hours of learning of the pregnancy.  The subject will also be followed to 
determine the outcome of the pregnancy.  Generally, follow-up will be no longer than 
6 to 8 weeks following the estimated delivery date.  Any premature termination of the 
pregnancy will be reported. 
All pregnancies will be reported from the site and documented according to the same 
procedures as SAE.  While a pregnancy will not be considered as an SAE, any pregnancy 
complication or elective termination of a pregnancy for medical reasons will be recorded 
as an AE or SAE. 
A spontaneous abortion is always considered to be an SAE and will be reported as such.  
Furthermore, any SAE occurring as a result of a post-study pregnancy and which is 
considered reasonably related to the investigational product by the Investigator, will be 
reported to the Sponsor. While the Investigator is not obligated to actively seek this 
information in former study participants, he or she may learn of an SAE through 
spontaneous reporting.  Subjects will be asked to contact the clinic in these situations. 
6.2.6 Disease-Related Assessments 
6.2.6.1 Urinary Sample Collections 
Urine will be collected in the containers provided.  Subjects will be asked to provide 
either two or four adequate 24-hour urine collections (ideally collected on sequential 
days) at the times indicated in the Time and Events Table (Appendix A).  The total 
volume of urine and urine creatinine excretion rates will be measured from the 24-hour 
collections as a marker of the adequacy of the collection as detailed below in this section. 
Collections judged to be inadequate may be repeated at discretion of the 
Investigator.  
Subjects should be instructed to avoid consuming ≥4 L/day of liquids on the day of urine 
collection. Subjects must also follow all of the lifestyle and dietary restrictions listed in 
Section 7. 
At Baseline, subjects will be asked to provide four adequate 24-hour urine collections.   
During the Dose Titration Phase, after the start of each dose and in order to assess the 
need for further dose titration, subjects will be asked to provide two adequately collected 
24-hour urine specimens starting at Day 10 (±1 day) after the start of each dose level, 
ideally on two consecutive days.  The two urine collections will be returned to the clinic 
on approximately Day 12. Urine volume will be measured at the clinic and samples will 
then be shipped frozen to the designated laboratory for measurement of UFC levels from 
each collection, as soon as possible upon receipt of the collections.  Section 4.2.1 
includes additional details of the dose titration process and determination of the 

Cortendo AB 
 
Protocol COR-2012-01 
AMENDMENT 6 
Page 61 of 119 
CONFIDENTIAL 
 
Therapeutic Dose.  As part of this process, two additional adequate 24-hour urine 
collections will be obtained to confirm a Therapeutic Dose has been reached, prior to 
entry into the Maintenance Phase. 
Four adequate 24-hour urine collections will be obtained just prior to the End of the 
Maintenance Phase visit. These urine collections are absolutely critical to the 
interpretation of the study results and the subject should be made fully aware of the 
need for their compliance with this collection.  Prior to each monthly visit after 
entering the Maintenance Phase and prior to the Month 9 and 12 visit of the Extended 
Evaluation Phase, two adequate 24-hour collections will be obtained, ideally on two 
consecutive days. 
Urine collections will begin after the first morning void (collection Day 1) and will be 
collected over 24 hours until the next morning, including the first void on the morning of 
collection Day 2.  Careful instructions must be provided to the subject on the process 
for proper urine collection and storage of samples over 24 hours. 
The total volume of urine and urine creatinine excretion rates will be measured from the 
24-hour collections as a marker of the adequacy of the collection.  Total urine volume 
should be 400 to 4000 mL/day.  
Minimum expected values for normal 24-hour creatinine excretion rates up to age 70 are 
provided in Table 2. 
Table 2 
Minimum Normal 24-Hour Creatinine Excretion from Adequate Urine 
Collections 
Males 
1. Age 18 to 50:  18.5 mg/kg/day 
2. Age 51 to 70:  15.7 mg/kg/day 
 
Females 
1. Age 18 to 50:  16.5 mg/kg/day 
2. Age 51 to 70:  11. 8 mg/kg/day 
 
In subjects over 70 years of age, creatinine excretion rates should 
be discussed on a case by case basis with the Medical Monitor. 
Due to the muscle wasting observed in CS and dependent on the length of the disease, 
subjects may have 24-hour urine creatinine excretion rates in the lower end of the ranges 
reported in Table 2 [Petersenn 2013].  
6.2.6.2 Urinary Sample Analysis 
UFC levels from the 24-hour urine collection will be assayed at a central laboratory 
according to the current validated methodology high pressure liquid chromatography 
tandem mass spectroscopy (HPLC/MS/MS). Details for handling of 24-hour UFC 
measurements and urine creatinine excretion rates will be provided in the SPM.

6.2.6.3 Late Night Salivary Cortisol 
Late night salivary cortisol samples will be collected by each subject at the times 
indicated in the Time and Events Table (Appendix A).  Saliva collections must be done 
between 11 pm and midnight and following the dietary restrictions listed in Section 7.  
Subjects should not sleep and subsequently awaken within two hours of collecting the 
saliva sample.  Late night samples from two nights, will be collected at Baseline, at the 
beginning of Maintenance Phase (Month 1) and just prior to the End of Maintenance 
Phase. Late night samples from one night will be collected at all other times indicated in 
Time and Events Table (Appendix A). All samples will be analyzed at a central 
laboratory with experience in salivary cortisol measurements.  All details for collection 
and handling of samples are provided in the SPM. 
6.2.6.4 Dexamethasone Suppression Test (DST) 
A DST (1 mg overnight test as described below) will need to be available at Baseline if 
not previously performed within the 2 months prior to start of Screening Phase, to 
confirm eligibility for participation in the study. In order to be fully interpretable, 
adherence to the timing requirement of the test will be important.  
Overnight DST 
• 1 mg dose of dexamethasone will be self-administered orally between 11 PM and 
midnight 
• Blood sample to measure serum cortisol must be obtained at approximately 8 AM 
the next morning; the exact time to be recorded in the CRF 
• Subjects will have nothing to drink or eat for at least 10 hours before the blood 
test. 
The following medications may affect the DST results: barbiturates, corticosteroids, 
phenytoin, and tetracyclines. 
Details of the assay are described in the SPM. 
6.2.6.5 ACTH 
ACTH levels will be measured in all subjects at all study visits starting with the Baseline 
Visit as listed in the Time and Events Table in Appendix A.  Details of the assay are 
described in the SPM. 
6.2.6.6 Pituitary Magnetic Resonance Imaging (MRI) 
Pituitary MRIs will be obtained for subjects with a diagnosis of CD at Baseline, if not 
done within 6 months of administration of the first dose of the study drug, just prior to the 
End of the Maintenance Phase, and at the end of the Extension Phase. The results of 
MRIs obtained during the study will be evaluated by a central reader (neuroradiologist).

6.2.6.7 Oral Glucose Tolerance Test 
All pre-diabetic subjects with screening fasting glucose concentrations >100 mg/dL but 
<126 mg/dL will have an OGTT at Baseline and at the times indicated in the Time and 
Events Table (Appendix A).  After an overnight fast of at least 12 hours, subjects will be 
asked to drink 75 g of glucose.  Blood samples for the determination of glucose 
concentrations will be drawn before glucose administration and 30, 60, 90, and 
120 minutes after administration.  Subjects with diabetes, as defined in Appendix H will 
be excluded from the OGTT. 
6.2.6.8 Quality of Life Measures 
The Cushing QoL questionnaire [Webb 2008] [Appendix L] and the Beck Depression 
Inventory (BDI-II) [Appendix N] instrument will be administered at the times indicated 
in the Time and Events Table (Appendix A). 
6.2.7 Situations Requiring Additional Safety Monitoring 
Additional safety monitoring will be required for the following situations. 
6.2.7.1 Dose Titration Higher than 600mg/day 
If titration levels go beyond 600 mg/day, subjects are required to return once 7 days 
(± 3 days) after each dose level escalation visit for DL4 through DL7 for additional safety 
evaluations which will include the following assessments: AEs, vital signs, routine safety 
laboratory assessments (LFTs), ECGs, and morning serum cortisol levels (see 
Section 4.2.2). 
6.2.7.2 QTc Prolongation 
In the event QTc prolongation occurs (as defined in Section 6.2.4.1), additional safety 
monitoring is required, including medical observation of the subject until the QTc has 
returned to a value ≤500 msec or ≤60 msec change from Baseline.  Additional evaluation 
of the subject, as described in Section 6.2.4.1, will include the potential requirement for 
additional ECGs, laboratory assessments and PK samples. 
6.2.7.3 Adrenal Insufficiency 
Subjects with suspected adrenal insufficiency should be assessed for signs and symptoms 
of adrenal insufficiency and cortisol levels as described in Section 6.3.3.  Should adrenal 
insufficiency be deemed present, study drug should be temporarily discontinued for mild 
symptoms/signs.  For moderate or severe symptoms/signs, study drug will be temporarily 
discontinued and rescue glucocorticoids administered as indicated. In addition, an 
additional PK sample should be collected as close to the time of the event as possible, 
ideally within several hours of dosing. 
Study drug at an appropriately lower dose can be restarted once the medical situation is 
deemed sufficiently resolved by the Investigator. Cases of suspected adrenal 
insufficiency should be reported to Cmed Pharmacovigilance as AESIs (Section 13.7).

6.2.8 Pharmacokinetics 
6.2.8.1 Pharmacokinetics Sample Collection 
Blood samples (1 mL minimum) for the determination of plasma concentrations of 
COR-003 will be collected at the times indicated in the Time and Events Table 
(Appendix A). 
The chosen dose level for PK sampling might vary from subject to subject. It is important 
to collect PK samples from subjects at higher dose levels.  Samples will be collected from 
different subjects at different dose levels. 
Subjects will be asked to provide the time of the last dose on the day prior to the PK 
sampling visit and to forego taking their medication on the day of the scheduled visit. All 
subjects will have a blood sample taken for PK immediately pre-dose and between 
1.5 and 2.5 hours post-dose.  PK samples for at least two different dose levels will be 
collected unless the Therapeutic Dose is reached at DL1.  The chosen dose levels for PK 
sampling might vary from subject to subject. It is important to collect PK samples 
from subjects at higher dose levels. A subset of at least 10 to 15 subjects will be asked 
to provide a third sample around 6 to 8 hours after dosing, for at least two different dose 
levels. 
In addition, if persistent and confirmed QTc prolongation is observed, an additional PK 
sample should be collected as close to the time of the event as possible, ideally within 
several hours of dosing (see Section 6.2.4).  Additional PK samples may also be collected 
in association with other AESIs as close to the time of the event as possible 
(Section 13.2.2). 
The actual PK times may vary from the nominal times; the actual dose administered, time 
of dose administration, and actual times of PK sample collection MUST be recorded. See 
SPM for further details. 
6.2.8.2 Pharmacokinetics Sample Analysis 
Sample analysis will be performed by Alturas Analytics (Moscow, Indiana USA) under 
the direction of Cortendo AB.  Concentrations of COR-003 (2S,4R-ketoconazole) in 
plasma will be determined using current validated methodology. See SPM for further 
details. 
6.3 Additional Considerations for Risk Management 
6.3.1 Instructions for Subjects 
Subjects will be instructed to carry a card at all times identifying the potential risk for 
adrenal insufficiency. This card will include subject’s information, contact information 
for the Investigator, and the potential need for glucocorticoids in cases of shock, surgery, 
and other conditions, as appropriate.  

Cortendo AB 
 
Protocol COR-2012-01 
AMENDMENT 6 
Page 65 of 119 
CONFIDENTIAL 
 
Subjects will be advised of the potential risk for adrenal insufficiency and be made aware 
of the signs and symptoms of this condition.  At any time during the study, subjects 
should contact the clinical site in the event of any emerging clinical signs and symptoms 
of an AE. Clear instructions should be provided to the subject on how to access the 
medical staff at the investigational site regardless of day or time of day. 
In addition, subjects will also be asked to carry an emergency kit containing 
hydrocortisone or another appropriate glucocorticoid, according to local medical 
practice, that can be administered immediately in case of adrenal insufficiency.  
6.3.2 Considerations for Investigator 
Subjects will be contacted (method by subject preference) approximately 1 week after 
taking the first dose and approximately 1 week after each dose adjustment to check on 
subject status and ensure compliance with medication administration.   
Throughout the study, subjects must be monitored and managed by the Investigator for 
the following diseases associated with CS or its treatment, according to recommended 
guidelines for diagnosis and standard of care: 
• Diabetes and impaired glucose tolerance:  See Appendix H for testing 
recommendations. 
• Hypertension:  See Appendix I for guidelines for classification of blood pressure 
levels and follow-up recommendations.  
• Hypocortisolemia:  See Appendix K for evaluations of signs and symptoms. 
• Hypomineralocorticoidism:  See Appendix K for evaluations of signs and 
symptoms. 
• Hypogonadism:  See Appendix K for evaluations of changes in sexual function as 
reported by the subject. 
• Acute adrenal crisis:  Acute adrenal crisis is a life-threatening condition that 
often occurs primarily because of mineralocorticoid deficiency (Appendix K).  In 
such cases, the major clinical problem is hypotension (low blood pressure or 
shock).  Adrenal crisis can result in seizures, shock, coma or death.  In patients 
treated for CS, adrenal crisis typically occurs in the setting of acute stress or 
pituitary infarction.  With pituitary infarction, glucocorticoid deficiency can 
predominate.  
• Adrenal insufficiency:  See the following section (Section 6.3.3) for assessment of 
signs and symptoms of adrenal insufficiency and Appendix K for evaluation of 
signs and symptoms of adrenal insufficiency. 
6.3.3 Adrenal Insufficiency 
All medical care providers identified by the subject, in addition to the Investigator, 
MUST be given sufficient written instructions about potential risks of adrenal 
insufficiency in subjects in this study. 

Cortendo AB 
 
Protocol COR-2012-01 
AMENDMENT 6 
Page 66 of 119 
CONFIDENTIAL 
 
It is well recognized that subjects with a good response to treatment for CS resulting in 
decreased, but not low, cortisol concentrations may exhibit signs and symptoms of 
adrenal insufficiency (non-life threatening) which may not be different than those of 
acute adrenal crisis, which is a life-threatening event warranting immediate medical 
intervention. Discrimination between the two may not be evident. Furthermore, subjects 
may have adrenal insufficiency without abnormal cortisol concentrations, but the 
concentrations, while within or above the normal range, are inappropriately low for the 
degree of physiological stress being experienced by the subject. These symptoms include: 
nausea, vomiting, abdominal pain, anorexia, malaise, fatigue, headache, 
arthralgias/myalgias, gastrointestinal discomfort, dizziness (particularly upon standing), 
irritability, depression, sweating, and fever. Subjects may have hypoglycemia as well. 
Therefore, subjects should be assessed for signs and symptoms AND cortisol levels as 
follows: 
• Full review of symptoms. 
• Lying and standing blood pressure measurements and pulse to evaluate postural 
changes.  
• Laboratory evidence of hypoadrenalism is defined as morning serum cortisol level 
< 3 μg/dL (LLN or the lower limit of the assay being used for clinical testing). 
Even if the serum cortisol and/or the UFC are within the normal range, the 
possibility of adrenal insufficiency should be considered, based on postural 
(orthostatic) vital sign changes and clinical signs and symptoms. Please see 
Appendix K for a list of clinical signs and symptoms.  
• Should adrenal insufficiency be deemed present, COR-003 should be temporarily 
discontinued for mild symptoms/signs. 
• For moderate or severe symptoms/signs, COR-003 will be temporarily 
discontinued and rescue glucocorticoids temporarily administered.  
• COR-003 at an appropriately lower dose can be restarted once the medical 
situation is deemed resolved. If the dose that caused adrenal insufficiency is 
150 mg/day, COR-003 should be completely discontinued, and the subject 
withdrawn from the study. 
All cases of suspected adrenal insufficiency should be reported as AESIs to Cmed 
Pharmacovigilance (Section 13.7). 
7 
LIFESTYLE AND DIETARY RESTRICTIONS 
Subjects must follow the following lifestyle and dietary restrictions throughout the study. 
• Consumption of grapefruit, lime juice and Seville oranges and products (i.e. sour 
orange, bigarade orange, or marmalade orange) should be avoided; 
• Genuine licorice should be avoided;  
• Consumption of excessive alcohol should be avoided;

CONFIDENTIAL 
 
Subjects must follow the following lifestyle and dietary restrictions for study-specific 
assessments. 
• During the 24-hour urine collection period, subjects must refrain from the 
following: 
o Drinking ≥4 L/day of fluids (which equals a little less than a gallon) 
o Use of medicines or products with glucocorticoids, such as hemorrhoid or 
steroid skin creams  
• On the nights that samples are collected for salivary cortisol test, subjects must 
refrain from the following: 
o Within 2 hours of the collection: 
 Brushing or flossing teeth or doing anything that could induce 
bleeding of the gums  
 Sleeping and subsequently awakening 
o Within 1 hour of the collection: 
 Eating or drinking or chewing anything (including tobacco) 
 Using any creams or lotions 
 Smoking cigarettes, pipe, cigar or any other substance. 
 
Information on subject’s job related to working shift hours will be collected by the site 
personnel.

INVESTIGATIONAL PRODUCTS 
8.1 Description of Investigational Product 
COR-003 (2S,4R-ketoconazole, also known as levoketoconazole) will be provided as 
150 mg tablets.  The tablets will be 3/8” round, biconvex, and unmarked with a pink film 
coat and supplied in foil induction sealed High Density polyethylene (HDPE) 
bottles. Refer to the Pharmacy Manual for details of labeling of the investigational 
product. 
8.2 Dosage and Administration 
COR-003 will be administered BID, approximately every 12 hours, according to the 
titration scheme described in Section 4.2.  Subjects will receive an adequate number of 
the investigational product at each visit prepared by the study pharmacist. 
8.2.1 Dosage Reduction and use of Dose Level 0 
In accordance with the guidance in Section 6.3.3 if the subject develops signs and/or 
symptoms of adrenal insufficiency (e.g., orthostatic hypotension, nausea, vomiting, 
abdominal pain), based on further investigation and clinical judgment, the Investigator 
may opt to stop dosing of the study medication to allow resolution of these symptoms. 
Similarly, dosage reductions following temporary drug interruption might be used to 
manage possibly drug-associated toxicities, including LFT elevations (Section 5.3.2) or 
QTC prolongation (Section 6.2.7.2).  In such cases, when the study medication is 

Cortendo AB 
 
Protocol COR-2012-01 
AMENDMENT 6 
Page 68 of 119 
CONFIDENTIAL 
 
restarted it should be reduced to the preceding dose level (as described in 
Section 6.2.4.2).  In the event that an observation is made at DL1 necessitating dose 
reduction, the subject may receive a lower dose of 150 mg once daily (DL0) at the 
discretion of the Investigator and agreement with agreement of the Medical Monitor.  
Subjects may subsequently resume the Dose Titration scheme, if appropriate at the 
discretion of the Investigator and agreement with the Medical Monitor. 
The 150 mg dose for DL0 may be administered in the evening except on the day of the 
in-clinic procedures, when the dose should be administered in the clinic to allow for post-
dosing ECG and PK assessments. 
8.3 Dose Rationale 
The effects of treating CS with any therapeutic agent is not generally predictable a priori. 
Ketoconazole a commonly used therapeutic agent has variable PK and is titrated to effect 
up to levels as high as 1800 mg to control severely ill CS patients. In most patients 
responsive to ketoconazole, doses average approximately 600 to 800 mg/day with the 
range of 200 to 1800 mg having been utilized to achieve normalization of cortisol levels 
[Nieman 2002; Pozza 2012]. 
Like ketoconazole, COR-003 is not expected to be administered at a fixed dose but will 
be titrated to effect in each subject.  COR-003 has been used in clinical trials up to a dose 
of 600 mg. The highest dose of 600 mg BID COR-003 (1200 mg total daily dose) is 
indicated during this trial, because some CS subjects may require higher levels of cortisol 
suppression to achieve control in this severe disease.  Any titration to a dose of COR-003 
higher than 300 mg BID (600 mg total daily dose and higher) will be guided by enhanced 
tolerability and safety monitoring as described in Section 4.2.2.  It is expected that 
titration to this highest dose will be the exception rather than the norm, based on the 
experience with ketoconazole and the potentially higher in vitro potency of COR-003 to 
inhibit key enzymes controlling adrenal cortisol synthesis.  A detailed description of 
preclinical and prior clinical data with COR-003 and rationale for dose selection is 
provided in the Investigator’s Brochure. 
8.4 Blinding 
This will be an open label study.  However, a study-specific data restriction plan (DRP) 
has been crafted to govern the availability of efficacy data, such that the Sponsor will not 
be able to discern the emerging efficacy profile of the drug during study conduct, thus 
reducing the possibility of introduced bias. 
8.5 Randomization and Treatment Assignment 
This is a non-randomized study.  All subjects that sign informed consent and meet 
eligibility criteria at Baseline will begin treatment on 150 mg BID.

DRUG SUPPLIES, DISPENSING, STORAGE AND ACCOUNTING 
9.1 Product Accountability 
The Investigator is responsible for investigational product accountability, reconciliation, 
and record maintenance.  In accordance with all applicable regulatory requirements, the 
Investigator or designated site staff must maintain investigational product accountability 
records throughout the course of the study.  The responsible person(s) will document the 
amount of investigational product received from and returned to Cortendo (when 
applicable), the amount supplied and/or administered to and returned by subjects, if 
applicable. 
9.2 Compliance Assessment 
Subjects will be asked to maintain a patient diary to record medication administration, 
urine sample collection, saliva sample collection, concomitant medications, and changes 
in condition. In addition, subjects should bring all empty medication bottles and unused 
medication with them to all visits except for the additional safety visit required in the 
Titration Phase for DL4 through DL7 (where empty medication bottles and unused 
medication will not be collected and accountability will not be performed). 
Accountability to determine compliance will be performed at all other visits. 
9.3 Treatment of Investigational Product Overdose 
There is no known antidote to COR-003.  Subjects should be medically managed 
according to their clinical condition, as appropriate.  Refer to Section 4.2.2 for 
administration of doses >600 mg/day.   
10 CONCOMITANT MEDICATIONS 
10.1 Permitted Medications 
Over the counter liquid and tablet antacids are allowed, but must be used in moderation 
and taken ≥2 hours after dosing with COR-003. A list will be provided.  
10.2 Prohibited Medications 
During the study, subjects are not allowed to take the following medications, a more 
complete list categorized by primary reason for prohibition is found in Appendix J. The 
Investigator is encouraged to contact the Medical Monitor for any questions. 
• Total daily dose of acetaminophen (paracetamol) >3g (increased liver toxicity 
risk); 
• Prescription or over the counter H2 receptor antagonists or proton-pump 
inhibitors or sucralfate (inhibition of drug absorption); 
• Statins other than pravastatin, fluvastatin and rosuvastatin; potentially eligible 
subjects should be switched to an allowed statin several weeks prior to the 
Baseline Visit whenever feasible to allow equilibration of blood lipids; 

Cortendo AB 
 
Protocol COR-2012-01 
AMENDMENT 6 
Page 70 of 119 
CONFIDENTIAL 
 
• Carbamazepine, fenofibrate (assay interference), carbenoxolone; 
• Genuine licorice (mineralocorticoid effects);  
• Steroidogenesis inhibitors or dopamine agonists (interference with drug effect, 
Appendix J, Table 9 and Table 10); 
• Megestrol acetate or medroxyprogesterone acetate and selected other synthetic 
progestins (see Appendix J, Table 11) [Schindler 2003]; 
• Any other drug treatments used to lower cortisol in CS that are subject to washout 
(Section 5.1 and Appendix J, Table 12) are prohibited throughout the study; 
• Weight loss medications (either prescription or over the counter, Appendix J, 
Table 13); 
• Drugs whose systemic exposure is potentially increased significantly by 
concomitant use of COR-003 (Appendix J, Table 15); 
• Medications that are strong CYP3A4 inhibitors or CYP3A4 inducers as they may 
interfere with the metabolism of COR-003. As examples, rifampicin, rifabutin, 
isoniazid, nevirapine and phenytoin may significantly reduce COR-003 
concentrations via CYP3A4 induction, and ritonavir may increase COR-003 
concentrations via CYP3A4 inhibition, and are therefore prohibited (Appendix J, 
Table 16); 
• Medications resulting in QTc prolongation as a direct effect or as a result of 
interaction with COR-003, examples include: cisapride, dofetilide, pimozide, 
quinidine. (Appendix J, Table 17).  However, in selected cases where no 
alternative medications are available, permission from the Medical Monitor may 
be sought; 
• Topical or inhaled corticosteroid preparations (interference with drug effect, 
Appendix J, Table 9);  
• The following herbal medicines: St John’s Wort, echinacea, gingko, goldenseal, 
yohimbe, red rice yeast, danshen, silybum marianum, Asian ginseng, schissandra 
sphenanther, shankhapushi, and Asian herb mixture (Xiao chai hu tang and 
Salboku-to); 
10.3 Medications to be Used with Caution 
• There are some medications that are often considered contraindicated when used 
with ketoconazole, due to an increased risk of AEs (Appendix J, Table 20). These 
medications should generally be avoided while the subject is participating in the 
study. However, they may be used in selected cases, particularly when they are 
used prior to study entry and when no alternative medications are available. Such 
usage should follow consultation and explicit permission from the Medical 
Monitor.  
• Medications that are weak or moderate CYP3A4 inhibitors or CYP3A4 inducers 
or that are metabolized by cytochrome P450 enzymes (CYPs) and plasma 
concentration increases moderately in the presence of ketoconazole, potentially 
resulting in increased drug effect, should be avoided if alternative therapy is 
available or should be used with caution; in that case, careful monitoring, with 
possible adjustments in doses, is recommended (see Appendix J, Table 18).

11 SUBJECT COMPLETION AND WITHDRAWAL 
11.1 Subject Completion 
Subjects who complete the End of Maintenance Phase Visit of the study, regardless of 
their response status, will be considered to have completed the study and are eligible for 
inclusion into the Extended Evaluation Phase. 
Subjects who complete the Extended Evaluation Phase (M12 Visit) and are not 
progressing into an expanded access program should return approximately 2 weeks after 
completion of treatment with COR-003 for the Follow-Up Visit (see Appendix A). 
11.2 Subject Withdrawal Criteria and Procedures 
Reasons for premature study withdrawal (i.e. do not return for all study visits), include, 
but are not limited, to the following (see also Section 5.3): 
• Safety reasons, either at the discretion of the Investigator or at the subject’s 
request 
• Protocol violations at the discretion of the Sponsor 
• Permanent study medication discontinuation 
• Concomitant therapy that could interfere with the results of the study, (the 
Investigator will report all such information on the CRFs and decide, in 
accordance with the Sponsor, whether the subject is to be withdrawn).  
All study withdrawals and their causes must be carefully documented by the Investigator 
on the CRF, and, if need be, on the AE form.   
If the subject chooses to withdraw or is otherwise withdrawn before completing the 
study, the Investigator should make every attempt to have the subject return to the clinic 
to complete all safety and PK assessments as outlined for the Follow-Up Visit in 
Appendix A (approximately 2 weeks following end of treatment with COR-003). If a 
subject is withdrawn before completing the Maintenance or Extended Evaluation Phases 
of the study, the reason for termination will be recorded.  All data gathered on the subject 
prior to termination will be made available to the Sponsor.   
12 DATA ANALYSIS AND STATISTICAL CONSIDERATIONS 
12.1 Population for Analysis 
Intent-to-Treat (ITT) Population: The ITT population will include all subjects who 
receive at least one dose of COR-003.  This population will be used for the evaluation of 
efficacy and all safety analyses. 
Maintenance (M) Population: The M population will consist of all subjects who enter 
the Maintenance Phase of the study. This population will be used for the supportive 
evaluation of all the primary and secondary efficacy endpoints.   

Cortendo AB 
 
Protocol COR-2012-01 
AMENDMENT 6 
Page 72 of 119 
CONFIDENTIAL 
 
Per Protocol (PP) Population: The PP population will consist of all subjects who enter 
the Maintenance Phase of the study and have no major protocol deviations that may 
affect efficacy. This population will be as supportive analysis for the analysis of the 
primary endpoint.   
12.2 Hypothesis 
The primary endpoint for this study will be the proportion of responders to COR-003 
following 6 months of dosing in the Maintenance Phase without a dose increase during 
that phase. Additionally, subjects who previously received radiation therapy and who 
exhibit no rebound increase in mean UFC following withdrawal of COR-003 
immediately after the end of the Maintenance Phase will be considered non-responders.  
The proportion of responders in the ITT population will be estimated along with 
corresponding two-sided 95% confidence interval (CI).  The null hypothesis to be tested 
is if the proportion of responders at the end of the Maintenance Phase visit is at most 20% 
versus the alternative hypothesis that the proportion of responders at the end of the 
Maintenance Phase visit is greater than 20%; COR-003 will be considered effective if the 
null hypothesis is rejected.  The hypothesis test is to have 90% power and two-sided 5% 
Type I error. 
12.3 Sample Size Determination 
A sufficient number of subjects (estimated at approximately 90) will be enrolled into the 
Dose Titration Phase of the study to ensure that at least 70 subjects complete the 6-month 
Maintenance Phase.  The 90 subjects to be enrolled in the Dose Titration Phase will 
constitute the primary analysis population (i.e. the ITT population).  Table 3 illustrates 
the power to exclude the null hypothesis of at most a 20% responder rate, given an 
alternative response of 35% for a two-sided 5% Type I error for the ITT population. 
Results will be evaluated using a two-sided 95% lower confidence bound for the response 
rate at the end of the Maintenance Phase visit.

As an example, if the observed response rate at the end of the Maintenance Phase visit is 
40% with 90 subjects, then the two-sided 95% CI is (30.0%, 50.9%) which would support 
efficacy. 
In addition, the sample size of 90 subjects will be adequate to test hypotheses associated 
with the change from Baseline in CS comorbidity biomarkers expressed as continuous

endpoints (secondary efficacy endpoints).  Table 4 displays the differences that can be 
detected for the secondary efficacy endpoints of CS comorbidities with 90% power for a 
two-sided 1% Type I error for 90 subjects (the 1% Type I error accounts for testing 
significance for these multiple secondary efficacy endpoints).  Results will be evaluated 
using two-sided 99% lower confidence bounds for the changes from Baseline at the End 
of the Maintenance Phase visit.

12.4 General Considerations for Data Analysis 
The SAS System, Version 9.1.3 (or higher), will be used for all analyses, unless 
otherwise specified. Continuous variables (e.g., age) will be summarized using the 
number of observations (n), mean, standard deviation (SD), median, minimum, and 
maximum. Categorical variables (e.g., sex, race) will be summarized using the number of 
observations (n) and percentage in each category.  
All data used in analyses and/or collected during the study will be provided in listings. 
12.4.1 Premature Withdrawal and Missing Data 
Subjects withdrawn prior to the end of the Maintenance Phase will be considered as 
prematurely withdrawn. All available data for subjects who prematurely withdraw from 
the study will be included in all analyses. At any visits for which four 24-hour urine 
samples are planned to be collected, at least two UFC collections must be adequate by 
volume and creatinine criteria to be able to derive the mean UFC and thus be considered 
as non-missing.  Study withdrawals, reasons for withdrawal, and missing UFC collections 
will be summarized. 
Analyses of data for specific visits will be performed using two different approaches to 
account for missing data during the Maintenance Phase: 

Cortendo AB 
 
Protocol COR-2012-01 
AMENDMENT 6 
Page 74 of 119 
CONFIDENTIAL 
 
1. At-Visit analysis: Missing values at post-Baseline assessments will not be 
replaced and will be regarded as missing in longitudinal analyses.  The 
longitudinal models account for missing data. 
2. Imputation analysis: Subjects withdrawing will be counted as failures for the 
primary efficacy analyses. 
At-visit analyses will be performed using the longitudinal models as the primary 
approach with the imputation approach as supportive.  Details will be provided in the 
SAP. 
12.5 Final Analyses 
12.5.1 Safety Analyses 
The final analysis of safety is considered to be coincident with the last subject visit 
following completion of the Extended Evaluation Phase (i.e. following at least 
12 months’ treatment at the Therapeutic Dose). Interim analyses of safety are planned to 
coincide with timing for the primary analysis of efficacy (i.e. after the final subject has 
completed Maintenance Phase) and for any unplanned interim efficacy analyses, in order 
to assess benefits and risks of treatment simultaneously. In addition, planned and 
unplanned safety analyses will be performed and reported on a limited basis in order to 
satisfy requirements of study oversight, for example to Institutional Review Boards and 
Competent Authorities. These limited analyses (e.g. common adverse reactions summary) 
will not be accompanied by assessments of potential benefits.  
The DSMB will review all SAEs and AESIs on a rolling basis and assess benefits and 
risk of therapy systematically at approximately 6-month intervals. 
12.5.1.1 
Extent of Exposure 
Study drug exposure will be summarized as the average daily dose, cumulative dose, and 
total number of days on study drug.  Total number of days on study drug will be 
calculated for each subject as the treatment stop date minus treatment start date plus one 
day.   
Study drug compliance between visits and cumulative study drug compliance will be 
calculated by dividing the number of study drug tablets used (total number dispensed 
minus total number returned/lost/wasted) by the total number of study drug tablets that 
should have been taken and multiplying the result by 100.  
The occurrence and timing of dose discontinuations as well as dose increases will be 
displayed in a listing.  Reasons for discontinuation and dose increases will also be 
reported in the listing. 
12.5.1.2 
Adverse Events (AEs) 
AEs will be coded using MedDRA and graded according to the National Cancer Institute 
Common Terminology Criteria for Adverse Events, version 4.0 [NCI CTCAE, 2009].  

Cortendo AB 
 
Protocol COR-2012-01

TEAEs will be of primary interest.  The proportion of subjects reporting at least one 
TEAE, at least one drug-related TEAE, at least one serious TEAE, at least one TEAE 
leading to discontinuation of study drug, and at least one TEAE leading to withdrawal 
from the study will be computed.  The number and the percentage of subjects reporting 
each TEAE will be summarized for all TEAEs, and separately for drug-related TEAEs, 
all serious TEAEs, all TEAEs leading to discontinuation of study drug, and all TEAEs 
leading to withdrawal from the study. 
The most common TEAEs are defined as those occurring in at least 5% of the ITT 
population. The number and the percentage of subjects reporting the most common 
TEAEs will be summarized.  Two-sided 95% CIs will be reported for such TEAEs. 
12.5.1.3 
Clinical Laboratory Evaluations 
A laboratory value that is within the normal range will be considered normal. A 
laboratory value that is outside the testing laboratory’s normal range will be considered 
an abnormal laboratory value.  The number and percentage of subjects with abnormal 
laboratory values will be summarized for each scheduled visit.  Shift tables will be 
constructed.  
Differences in laboratory values between Baseline and each scheduled laboratory 
assessment will be calculated for each laboratory test and summarized descriptively. The 
laboratory test values obtained at Baseline closest to the start of treatment will be used as 
the Baseline value.   
Further details of the categorical analysis of the laboratory evaluation and on the LFT 
evaluations will be defined in detail in the SAP. 
12.5.1.4 
Vital Signs 
Heart rate and three measurements of SBP and DBP will be taken at each visit. The mean 
of these measurements will be used as the value for each visit. Baseline will be defined as 
the mean of the values from the measurement at Baseline just prior to the start of 
treatment.  Change from Baseline for each measurement will be summarized.  In 
addition, values of clinical importance (Table 5) will be identified in the data listings.

12.5.1.5 
Electrocardiograms (ECGs) 
Summary ECGs, based on the measurement of an ECG over 5 minutes as described in 
Section 6.2.4 will be used for each evaluation.  Quantitative ECG measurements (PR 
interval, QRS duration, HR, QT interval, QTcB interval, and QTcF interval) and changes 
from Baseline will be summarized descriptively.  ECGs results will be available to the 
Investigator shortly after being obtained and all ECGs will be reviewed by a central 
consulting cardiologist. The data from the central consulting cardiologist will be used in 
the evaluation of the drug effect.  While on study treatment, a QTc > 500 msec or > 60 
msec above Baseline will be of special interest (See Section 13.2.2). 
Categorical changes from Baseline and QTc values from each visit will be summarized 
by worst change and by visit. The clinically important categories (Table 6) of actual and 
change values will be tabulated and provided as listings.

Continuous ECG outcomes will be assessed using a paired t-tests while normal-abnormal 
shift tables will be assessed using a McNemar’s paired comparison tests. 
12.5.1.6 
Other Safety Measures 
Results from the DST during the Screening Phase will be listed by subject. ACTH, IGF-1 
and testosterone levels will be listed and summarized descriptively by time point. Results 
from pituitary MRI (tumor size) will be listed by subject and time point and descriptively 
summarized.  
12.5.2 Efficacy Analyses 
All efficacy analyses will be performed on the ITT and M populations using longitudinal 
models.  For the primary endpoint, imputation will be applied for subjects that were 
prematurely withdrawn from the study as supportive analysis. In addition, the primary 
endpoint will also be analyzed using the PP population as supportive analysis. 
Withdrawn subjects prior to the End of the Maintenance Phase Visit assessment, as well 
as those requiring a dose increase during the Maintenance Phase, will be considered non-
responders as long as the dose increase was sustained.  Additionally, subjects who 
previously received radiation therapy and who exhibit no rebound increase in mean UFC 
following withdrawal of COR-003 immediately after the end of the Maintenance Phase 
will be considered non-responders. 
12.5.2.1 Primary Efficacy Analysis 
Clinical Response Rate 
UFC data will be averaged for the End of Maintenance Phase Visit and then analyzed for 
response. The treatment estimate of the clinical response rate at the end of the 
Maintenance Phase and its associated two-sided 95% CI will be obtained from a repeated 
measures GEE model with a logit link using SAS PROC GLIMMMIX with LSMEANS 
statement.  The primary analysis will be the ITT population and analysis will be repeated 
in the M population and PP population. The longitudinal model will include visit, the 
concurrent CS medical conditions (diabetes, hypertension) as Baseline covariates as well 
as age (rounded median split), sex, disease duration, prior CS therapy, and prior radiation 
therapy, and subject will be included as a random effect.   
Dose level information for the M population and PP population will be summarized. 
If the lower bound of the 95% CI for the LSMEAN proportion of responders in the ITT 
population is ≥20% in the ITT population, then COR-003 will be considered effective.   
Although the End of Maintenance Phase marks the final analysis of primary efficacy, the 
clinical response rate will also be analyzed after each month of treatment in the 
Maintenance Phase and (secondary endpoint) and after 9 and 12 months in the extension 
phase (exploratory endpoint).

12.5.2.2 Secondary Efficacy 
UFC Analysis 
Clinical Response Rates  
UFC data will be averaged at each nominal visit and then analyzed for response in the 
same manner as for primary endpoint using the longitudinal models described in 
Section 12.5.2.1.  The proportion of UFC responders to COR-003 (defined similarly to 
the primary endpoint) along with associated 95% CIs will also be individually estimated 
at Months 1, 2, 3, 4, and 5 of the Maintenance Phase.  The longitudinal model estimates 
and the Nominal Visit estimates will both be presented.   
Complete and Partial Response Rates  
The proportion of subjects with complete and partial responses (≥ 50% reduction in mean 
UFC from Baseline at Months 1, 2, 3, 4, 5, and 6 of the Maintenance Phase) will be 
calculated and reported alongside with its associated 95% CIs and will be estimated from 
a repeated measurement model with the same covariate as for the primary endpoint 
analysis.  
Change in UFC 
Mean UFC will be calculated from adequate 24-hour urine collections. At Baseline and 
End of Maintenance Phase where four samples are to be collected, the mean UFC will 
only be calculated if there are at least two adequate samples.  The mean UFC from the 
collections at each visit will be used in the analysis of UFC.  UFC will be summarized by 
time point using descriptive statistics. In addition, change from Baseline and percent 
change from Baseline will be calculated for each post-Baseline assessment. Mean and 
individual plots of each endpoint over time will be presented for the Maintenance Phase.  
Paired t-tests will also be presented for the change from Baseline to each nominal visit. 
In addition, a shift table will be created to summarize the shift from Baseline to each 
post-Baseline time point using the following UFC normality categories: less than LLN, 
normal range, greater than ULN and less than 2X ULN, 2X to 5X ULN, 5X ULN to 10X 
ULN, greater than 10X ULN.  Shift analyses will be conducted using a generalized 
McNemar paired comparison test to account for the multiple categories. 
Salivary and Serum Cortisol Levels 
Mean salivary and serum cortisol levels will be calculated after 1, 2, 3, 4, 5, and 6 months 
of dosing in the Maintenance Phase.  Change from Baseline and percent change from 
Baseline and at-visit values will also be listed and summarized descriptively by visit.  
Values at each post-Baseline Visit will be compared with Baseline using a paired t-test. 
CS Comorbidity Biomarkers 
The changes from Baseline and percentage change from Baseline in individual 
biochemical markers of CS comorbidities (fasting glucose, HbA1c, SBP, DBP, total 
cholesterol, LDL and HDL cholesterol, and body weight) will be summarized at Months

1, 2, 3, 4, 5, and 6 of the Maintenance Phase.  In addition, shifts from Baseline (with 
regards to laboratory normal range) in individual biochemical markers of CS 
comorbidities will be analyzed using a t-test paired comparison test at each scheduled 
visit. 
Calculations for the CS comorbidity biomarkers will be performed using SAS PROC 
MIXED to account for all post-Dose Titration Phase outcomes per subject with changes 
from Baseline and two-sided 99% lower confidence bounds calculated using LSMEANS. 
To account for endpoint multiplicity, conservative 99% CIs will be computed instead of 
95% CIs.  The longitudinal model will include visit, the concurrent CS medical 
conditions (diabetes, hypertension) as Baseline covariates as well as age (rounded median 
split), sex, disease duration, prior CS therapy, and prior radiation therapy, and subject as 
a random effect.   
Clinical Signs and Symptoms 
Each individual clinical sign and symptom, defined in Appendix M, will be summarized 
at each time point for assessment by number and percent of subjects.  
Each sign and symptom present at Baseline will be graded on a 0 to 3 severity scale 
(0=absent, 1=mild, 2=moderate, 3=severe).  For each subject, the severities will be 
added.  A paired t-test will be used to test if there is a significant reduction in severity at 
each visit. 
In addition, shift tables in individual clinical signs and symptoms at each post-Dose 
Titration Phase visit will be created to demonstrate any improvement gained during the 
course of treatment and analyzed using a McNemar paired comparison test. 
Cushing’s Syndrome Quality of Life Questionnaire  
QoL (Appendix L) measures and changes from Baseline will be summarized by time 
point using descriptive statistics and analyzed using a paired t-test.   
Beck’s Depression Questionnaire 
Changes from Baseline for the Beck’s Depression questionnaire (Appendix N) will be 
summarized by time point using descriptive statistics and analyzed using a paired t-test. 
Only subjects recruited under the protocol amendment or subsequent amendment will be 
included in the summary table. All data will be listed. 
Glucose Tolerance Test 
For pre-diabetic subjects as determined by the Investigator as Baseline, the number and 
percent of subjects after 3 and 6 months of dosing in the Maintenance Phase will be 
summarized for each of the following categories. 
• Normal: 2-hour glucose level is <140 mg/dL 
• Impaired glucose tolerance (pre-diabetic): glucose level ≥140 mg/dL and 
≤200 mg/dL 
• Provisional diagnosis of diabetes (diabetic): glucose level ≥200 mg/mL

CONFIDENTIAL 
 
Glucose values during the OGTT will also be summarized by maximum value, time to 
maximum value, and AUC, and statistically analyzed with a paired t-test for each 
assessment. 
Spot Albumin/Creatinine Ratio  
For subjects who have abnormal albumin/creatinine ratio at Baseline, albumin/creatinine 
ratio and its change from Baseline after 3 and 6 months of dosing in the Maintenance Phase 
will be summarized.  At-visit values will be compared with Baseline using a paired t-test. 
CRP 
CRP value and its change from Baseline after 1, 2, 3, 4, 5 and 6 months of dosing in the 
Maintenance Phase will be summarized. 
12.5.2.3 Exploratory Efficacy 
The analyses described above in Section 12.5.2.2 for clinical response rate, complete and 
partial response rate, changes in UFC, serum and late night salivary cortisol, QoL 
(Cushing’s QoL questionnaire and Beck’s Depression Index), and change in CS 
comorbidities, OGTT, albumin/creatinine and CRP will be repeated for the Extended 
Evaluation period using the same approach as for the Maintenance Period. 
Clinical Benefit 
The proportion of subjects achieving clinical benefit at Months 1, 2, 3, 4, 5, and 6 during 
the Maintenance Phase and Months 9 and 12 in the Extended Evaluation Phase will be 
displayed graphically over time with clinical benefit defined as: 
1. Clinical response as indicated by UFC ≤ ULN, and 
2. No increase in COR-003 dose during Maintenance Phase, and 
3. A clinically meaningful improvement in any one Baseline CS comorbidity 
(diabetes, hypertension, hypercholesterolemia, weight) as will be defined in 
the SAP and  
4. No study drug related TEAE classified as severe or worse. 
Medication Changes 
Changes to concomitant medications (in particular for blood pressure, diabetes and 
cholesterol management) will be listed by subject.  In addition, the number and percent of 
subjects with medication changes during the course of the study will be summarized. The 
proportions with dose increases and decreases including new and discontinued 
medications will be displayed.   
Clinical Signs of Hypercortisolism (Photographs) 
At Baseline, End of Maintenance Phase Visit, and End of Extended Evaluation Phase 
Visit, the adjudication committee, composed of three clinician-investigator experts in CS 
will assess the subjects for changes in visible signs of hypercortisolism (e.g. moon face, 
plethora, supraclavicular and dorsal fat pads, striae, hirsutism, bruising and overall body

habitus, if available) by scoring longitudinal photographs.  The scoring will be based on 
overall subjective impression of changes from Baseline as follows: obvious visible 
worsening, subtle visible worsening, no visible changes, subtle visible improvements, 
obvious visible improvements. Other methods of scoring photos may be included in the 
SAP. 
Relationship Between QTc Interval and COR-003 
The number and percentage of subjects with abnormal QTc, QTcB and QTcF results 
(abnormal categories are defined as > 450 msec, > 480 msec, > 500 msec, > 30 msec 
increase from Baseline and > 60 msec increase from Baseline) will be summarized for 
each dose level after 1, 2, 3, 4, 5 and 6 month of treatment in the Maintenance Phase and 
after 9 and 12 months in the Extended Evaluation Phase. Subjects will be summarized 
under their therapeutic dose or the maximum dose reached during the Dose Titration 
Phase if the subject discontinued prior to entering the Maintenance Phase. 
12.5.3 Pharmacokinetics Analysis 
PK model parameters will include: CL/F, V/F, Ka with associated between subject 
variability where feasible.  Model parameters will be tabulated with associated precision.  
Derived parameters including t½, AUC and Cmax will be reported, if appropriate. 
Because the PK of ketoconazole are reported to change over time, time dependent 
changes in CL/F, AUC, and t½ will be investigated and, if identified, changes will be 
described in the model. Derived parameters will be tabulated with associated summary 
statistics. 
PK data will be evaluated using a population modeling-based approach as implemented 
in NONMEM® (Version 7 level 2 or higher).  Subjects with at least one adequately 
documented dose and concentration record will be considered for inclusion in the 
population PK evaluation.  All evaluations will be conducted based on a pre-specified 
analysis plan. Standard model building and model evaluation procedures will be 
followed.  Derived parameters will be calculated from the final model. 
12.5.4 Pharmacodynamics Analysis 
The PD model parameters including UFC Imax, COR-003 dose producing UFC IC50, 
and associated estimates of between subject variability will be reported.  Individual 
maximal UFC reductions achieved will be tabulated and summary statistics (mean, 
median, SD and percent coefficient of variation) will be presented.  Stochastic 
simulations of the expected response for the preferred dose regimen will be generated to 
explore the range of UFC reduction. 
PD data (UFC) will be evaluated using a population modeling-based approach as 
implemented in NONMEM® (Version 7 level 2 or higher).  Subjects included in the 
population analysis with at least one adequately documented dose, PK record and UFC 
record will be considered for inclusion in the population PD evaluation.  All evaluations 
will be conducted based on a pre-specified analysis plan. Standard model building and

model evaluation procedures will be followed.  Derived parameters such as maximal 
response will be calculated from the final model as appropriate. 
12.5.5 Subgroup Analyses 
Subgroup analyses for the primary endpoint and CS comorbidities endpoints will be 
performed for a minimum subgroup size of at least 30% of the ITT population. Details 
will be covered in the SAP. 
12.5.5.1 Prior Therapy for Cushing’s Syndrome 
Subgroup displays for the primary endpoint and the CS comorbidities endpoints will be 
generated for subjects that enter the study as medical treatment-naïve vs. medical 
treatment-experienced and surgery-naïve versus surgery-experienced. Subgroup analyses 
by number of prior surgeries, time since last surgery, and category of prior medical 
treatment will also be explored. 
12.5.5.2 Prior Radiation Therapy 
Subset displays for the primary endpoint and the CS comorbidities endpoint will be 
generated, excluding subjects who previously received radiation therapy.  The total 
number of previously irradiated subjects will not exceed 10.  
Note: A drug holiday after the last Maintenance Phase visit will be used to determine if 
UFC normalization during the Maintenance Phase can be attributed to COR-003 or to 
prior radiation therapy (i.e. a loss of normalization during temporary drug interruption 
will implicate COR-003 as primarily responsible for UFC normalization). 
12.5.5.3 Hypertensive Subjects 
Subgroup displays for the primary endpoint and the CS comorbidities endpoint will be 
generated for subjects who enter the study while being prescribed antihypertensive 
medications versus not and subjects who enter the study with a Baseline SBP 
>130 mmHg or DBP >90 mmHg regardless of antihypertensive medication status versus 
those with lower BP recordings. 
12.5.5.4 Pre-diabetic/Diabetic Subjects 
Subgroup displays for the primary endpoint and the CS comorbidities secondary efficacy 
endpoint will be performed for subjects who enter the study as pre-diabetic (Baseline 
fasting serum glucose >100 mg/dL but <126 mg/dL without concomitant use of 
antihyperglycemic medication) versus those with normal fasting glucose or diabetic 
(Baseline fasting serum glucose >126 mg/dL or lower fasting glucose while being 
prescribed antihyperglycemic medications) versus those without diabetes. Subgroups 
based on findings from stimulated glucose during the Baseline OGTT will also be 
generated.

13 ADVERSE EVENTS (AE) AND SERIOUS ADVERSE EVENTS (SAE) 
The Investigator and study staff are responsible for detecting and recording AEs and 
SAEs during scheduled safety evaluations and whenever such information is brought to 
their attention. This section of the protocol provides definitions and detailed procedures 
to be followed. 
During each visit, the Investigator will question the subject about AEs using an open 
question taking care not to influence the subject’s answers, e.g. "have you noticed any 
change in your health?” 
13.1 Definition of an AE 
An AE is any untoward medical occurrence in a study subject that is temporally 
associated with the use of a medicinal product, regardless of its potential relationship to 
the medicinal product.  An AE, therefore, can be any unfavorable or unintended sign, 
including an abnormal laboratory finding, symptom, or disease (new or exacerbated), 
whether or not related to the study drug or study conduct.   
Examples of an AE include: 
• Exacerbation of a pre-existing condition including either an increase in frequency 
and/or intensity of the condition. 
• New conditions detected or diagnosed after investigational product administration 
even though it may have been present prior to the start of the study. 
• Signs, symptoms of a drug interaction. 
• Signs, symptoms of a suspected overdose of either investigational product or a 
concurrent medication.  
• A laboratory abnormality worsening or newly occurring after the start of the study 
(i.e., after Screening) that results in subject withdrawal from the study or medical 
treatment or further follow-up. 
NOTE: Abnormal values that reflect hypercortisolism (UFCs, salivary and serum cortisol) 
will not be recorded as AEs. AEs may include pre- or post-treatment events that occur as 
a result of protocol-mandated procedures (i.e., invasive procedures, modification of 
subject’s previous therapeutic regimen). 
13.2 Definition of a SAE 
An SAE is any untoward medical occurrence that, at any dose: 
(a) results in death; 
(b) is life-threatening; 

Cortendo AB 
 
Protocol COR-2012-01 
AMENDMENT 6 
Page 84 of 119 
CONFIDENTIAL 
 
NOTE:  The term 'life-threatening' in the definition of 'serious' refers to an event in which 
the subject was at risk of death at the time of the event.  It does not refer to an event, 
which hypothetically might have caused death if it were more severe. 
(c) requires hospitalization or prolongation of existing hospitalization; 
NOTE:  In general, hospitalization signifies that the subject has been detained (usually 
involving at least an overnight stay) at the hospital or emergency ward for observation 
and/or treatment that would not have been appropriate in the physician’s office or out -
patient setting.  Complications that occur during hospitalization are AEs.  If a 
complication prolongs hospitalization or fulfills any other serious criteria, the event is 
serious.  When in doubt as to whether “hospitalization” occurred or was necessary, the 
AE should be considered serious. 
(d) results in disability/incapacity; 
NOTE:  The term disability means a substantial disruption of a person’s ability to 
conduct normal life functions.  This definition is not intended to include experiences of 
relatively minor medical significance such as uncomplicated headache, nausea, vomiting, 
diarrhea, influenza, and accidental trauma (e.g. sprained ankle) which may interfere or 
prevent everyday life functions but do not constitute a substantial disruption. 
(e) is a congenital anomaly/birth defect, or 
(f) Medical or scientific judgment should be exercised in deciding whether reporting is 
appropriate in other situations, such as important medical events that may not be 
immediately life-threatening or result in death or hospitalization but may jeopardize 
the subject or may require medical or surgical intervention to prevent one of the 
other outcomes listed in the above definition.  These should also be considered 
serious.  Examples of such events are invasive or malignant cancers, intensive 
treatment in an emergency room or at home for allergic bronchospasm, blood 
dyscrasias or convulsions that do not result in hospitalization, or development of 
drug dependency or drug abuse. 
13.2.1 Disease-Related Events 
Although symptoms of CS are quite non-specific, all AEs and their attributions will be 
collected and reviewed.  The reduction in cortisol levels, regardless of therapeutic 
intervention, is known to cause symptoms (e.g., nausea, lethargy, muscle aches), and 
these too will be captured as AEs for evaluation. 
13.2.2 Adverse Events of Special Interest (AESI) 
A serious or non-serious event of scientific and medical concern specific to a Sponsor’s 
product or program, for which ongoing monitoring and rapid communication by the 
Investigator to the Sponsor can be appropriate. Such an event might warrant further 
investigation in order to characterize and understand it. 

Cortendo AB 
 
Protocol COR-2012-01 
AMENDMENT 6 
Page 85 of 119 
CONFIDENTIAL 
 
AESIs should be reported to the designated safety group as per Section 13.7 
regardless of seriousness or causality.  Upon receipt, these AEs will be captured in the 
safety database, targeted follow-up queries will be sent to sites, and source 
documentation will be sent to the DSMB.  As deemed appropriate, analysis of any 
unscheduled PK samples collected in association with AESIs may be expedited. Once 
uploaded and reconciled in the clinical database, these results will be forwarded to the 
DSMB. 
The AESIs for this study are defined as follows: 
 Persistent QTc prolongation:  Persistent elevation of the QTc interval is defined 
as absolute QTc interval >500 msec (or >60 msec above Baseline), with an ECG 
evaluation on repeat determination continuing to demonstrate QTc prolongation in the 
absence of plausible alternative explanations. 
 
 Potential hepatic events:  Signs of hepatic dysfunction, such as: 
• ALT or AST >8X ULN 
• ALT or AST rises to >5X ULN in <4 weeks or persists for >2 weeks 
• ALT or AST >3X ULN and TBN >2X ULN or INR >1.5 not explained by any 
other cause such as viral hepatitis, and without evidence of cholestasis 
• ALT or AST >3X ULN with new onset of or worsening of fatigue, nausea, 
vomiting, fever, rash or eosinophilia, in the absence of other evident cause 
• Signs and /or symptoms suggestive of hepatic dysfunction (any of the following: 
nausea, anorexia, fever, fatigue, right upper quadrant discomfort, pruritus, dark 
urine or acholic stool) coupled with ALT and/or AST >3X ULN and/or AP >2X 
ULN, and/or TBN >2X ULN in the absence of evidence for obstruction or Gilbert 
syndrome. An ultrasound evaluation of the gallbladder and bile duct should be 
conducted to exclude cholestasis as the cause for elevated AP and/or TBN. 
 
 Adrenal insufficiency:  A suspicion or diagnosis of adrenal insufficiency, based on 
the considerations laid out in Section 6.3.3. 
13.3 Time Period, Frequency, and Method of Detecting AEs and SAEs 
As a consistent method of soliciting AEs, the subject should be asked a non-leading 
question such as: "How do you feel?"  
All AEs occurring after obtaining the informed consent until the end of the final visit 
must be reported.  All AEs must be recorded irrespective of whether they are considered 
drug-related. 
At each visit/assessment in the period defined above, AEs will be evaluated by the 
Investigator and recorded. 

Cortendo AB 
 
Protocol COR-2012-01 
AMENDMENT 6 
Page 86 of 119 
CONFIDENTIAL 
 
Any AEs already documented at a previous assessment and designated as ongoing, 
should be reviewed at subsequent visits as necessary.  If these have resolved, this should 
be documented.  Changes in intensity or frequency of AEs should be recorded as separate 
events (i.e., a new record started). 
The recording of AEs and SAEs are described in Section 13.4 (“Recording of AEs and 
SAEs”). 
13.4 Recording of AEs and SAEs 
All clinical events, including either observed or volunteered problems, complaints or 
symptoms are to be recorded on the Adverse Events page(s) of the CRF.  The need to 
capture this information is not dependent upon whether the clinical event is associated 
with study treatment. Adverse clinical events resulting from concurrent illnesses or 
reactions to concurrent medications are also to be recorded.  In order to avoid vague, 
ambiguous, or colloquial expressions, the AE should be recorded in standard medical 
terminology rather than the subject’s own words. 
Each adverse clinical event is to be evaluated for duration, intensity, and whether the 
event may be associated with the study drug or other causes.  Start and stop dates, 
relationship to study drug, medical management, and alternative causality of event must 
be recorded in the Adverse Events section of the CRF.  AEs believed to be possibly 
related to study drug must be followed until resolution. 
13.5 Evaluating AEs and SAEs 
13.5.1 Severity Rating 
The severity of AEs and SAEs will be graded according to NCI CTCAE, Version 4.0.  
Grade 1  
Mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; 
intervention not indicated 
Grade 2  
Moderate; minimal, local or noninvasive intervention indicated; limiting age-appropriate 
instrumental activities of daily living 
Grade 3  
Severe or medically significant but not immediately life-threatening; hospitalization or 
prolongation of hospitalization indicated; disabling; limiting self-care activities of daily 
living 
Grade 4 
Life-threatening consequences; urgent intervention indicated 
Grade 5 
Death related to AE 
An AE that is assessed as severe should not be confused with an SAE.  An event is 
defined as ‘serious’ when it meets one of the pre-defined outcomes as described in 
Section 13.2 “Definition of a SAE”. 
13.5.2 Relationship to Study Drug 
SAEs will be classified as “not related” or “related” (including unknown).  
For AEs, the relationship to study treatment is to be assessed according to the following 
definitions: 

Cortendo AB 
 
Protocol COR-2012-01 
AMENDMENT 6 
Page 87 of 119 
CONFIDENTIAL 
 
Definitely not related: The AE is definitely not related to the drug.  This 
designation should be reserved for those events which occur prior to study 
treatment or for those events which cannot be even remotely related to study 
participation (e.g., injuries sustained in an automobile accident). 
Unlikely: There is no reasonable association between the study treatment and the 
suspected event and the event could have been produced by the subject's clinical 
state or other modes of therapy administered to the subject. 
Possibly related:  The suspected event may or may not follow a reasonable 
temporal sequence from study treatment administration but seems to be the type 
of reaction that cannot be dismissed as unlikely.  The event could have been 
produced or mimicked by the subject's clinical state or by other modes of therapy 
concomitantly administered to the subject. 
Probable: The suspected event follows a reasonable temporal sequence from 
study treatment administration, abates upon discontinuation of the treatment, and 
cannot be reasonably explained by the known characteristics of the subject's 
clinical state. 
Definitely related: This designation should be reserved for those events which 
have no uncertainty in their relationship to treatment administration. 
13.6 Follow-Up of AEs and SAEs 
After the initial AE/SAE report, the Investigator is required to proactively follow each 
subject.  Further information on SAEs will be provided to the Sponsor’s designated safety 
group on the subject’s condition within 24 hours as described in Section 13.7. 
New or updated information will also be recorded on the “SAE” CRF within 24 hours. 
13.7 Prompt Reporting of SAEs to Sponsor 
Any SAE, occurring in a subject who has signed the informed consent or if the 
Investigator becomes aware of any SAE post-treatment during the follow-up period, must 
be reported by the Investigator to the Sponsor’s designated safety group within 24 hours 
even if the SAE does not appear to be drug-related. This should be done by emailing or 
faxing a copy of the SAE Report form plus other related information to Sponsor’s 
designated safety group.  The SAE may be reported by telephone; however, this should 
be followed up within 24 hours with a copy of the SAE Report form.  Additionally, it 
may be necessary for the designated safety group to communicate with the Investigator if 
additional information is required.   
Regardless of seriousness or causality, AEs designated as AESI (instances of persistent 
QTc prolongation, potential hepatic events, and potential adrenal insufficiency) should be 
reported to the Sponsor’s designated safety group within 24 hours, in the same manner as 
SAEs (see also Section 13.2.2).

All additional follow-up evaluations must be reported to Cortendo’s designated safety 
group.  Such data should be sent to the Sponsor within 24 hours.  All SAEs will be 
followed until the Investigator and Sponsor agree the event is satisfactorily resolved. 
The Sponsor will be responsible for completing the safety report and for notifying the 
relevant authorities of any SAE as outlined in the International Conference on 
Harmonization (ICH) Guidelines and per local regulatory requirements.  The Investigator 
and Cortendo’s designated safety group will also ensure that the appropriate Institutional 
Review Boards (IRBs)/Independent Ethics Committees (IECs) are notified of the SAE.

1 The approximate interval between dose adjustments will be 18 days (±4 days) including reporting time for UFC levels and safety laboratory assessments. If 
additional UFC collections are required, the approximate interval between either dose adjustments or to transition to maintenance should be 30 days (±7 days) to 
allow for additional testing and reporting time.  DL0 is a lower dose of 150 mg once daily that may be used if the subject develops signs and/or symptoms of 
adrenal insufficiency at DL1 and is to be restarted on a reduced the dose after their resolution (see Section 6.3.3 and 6.2.4.2). 
2 Maintenance visits should occur every 30 days (±7 days). 
3 Extended Evaluation visits should occur every 90 days (±14 days). 
4 Subjects who complete the Extended Evaluation Phase (M12 Visit) and are not progressing into an expanded access program should return approximately 
2 weeks after completion of treatment with COR-003 for the Follow-up Visit (and no later than 30 days). NOTE: The Follow-Up Visit is not required for subjects 
continuing into expanded access treatment.  
5 Screening procedure to be performed following ICF and PRIOR to washout (if necessary) 
6 Baseline procedures should be performed within 14 days (± 7 days) of DL1 visit. 
7 Medical history to include previous documentation of diagnosis of Cushing’s syndrome, and data on all previous LFTs, as medical records permit.  Medical 
histories should be updated at Baseline. 
8 Blood pressure, diabetes, cholesterol medications will be specifically reviewed.

STUDY MANAGEMENT AND MATERIALS 
Study Documentation 
The Investigator is required to prepare and maintain adequate and accurate case histories 
(i.e., source documents and/or Medical Record Supplement) designed to record all 
observations and other data pertinent to the study for each study participant.  This 
includes accurate documentation of accountability of study medications.  The medical 
records must contain adequate information to allow for verification of subject identity 
throughout the study.   
Electronic CRFs will be completed for each subject who is enrolled in the study. Subject 
numbers will be assigned by the eCRF system immediately following the performance of 
informed consent.  A subject screening/enrollment log, noting reasons for screen failure 
where applicable, will be maintained for all subjects who are consented. 
All information recorded on the CRFs for this study must be consistent with the subject’s 
source documentation (i.e., source documents and/or Medical Record Supplement).  The 
source documents may include the hospital and/or the physician’s chart, X-rays, or 
laboratory test documentation.   
The CRFs for each subject will be periodically checked against the subject’s source 
documents at the study site by the site monitor.  Instances of missing or unclear data will 
be discussed with appropriate site personnel for resolution.  A quality assurance audit will 
be performed on the database. 
Archiving of Study Documentation 
The Investigator shall retain records for two (2) years following the date a marketing 
application is approved for the indication pertaining to this clinical study; or, if the drug 
is planned to be terminated or if a regulatory application is not planned to be progressed, 
until two (2) years after the investigation is discontinued and the Food and Drug 
Administration (FDA) or a competent regulatory authority is notified. 
The Sponsor will inform the Investigator, in writing, as to when these documents no 
longer need to be maintained. 
Monitoring and Quality Assurance 
During the course of the study, a monitor will make routine site visits to review protocol 
compliance, compare CRFs with individual subject’s original source documents, assess 
drug accountability and ensure that the study is being conducted according to pertinent 
regulatory requirements.  The review of the subjects’ original medical records will be 
performed in a manner to ensure that subject confidentiality is maintained.

ADMINSTRATION AND REGULATORY POLICIES 
Ethical Conduct of Study 
The Investigator(s) should conduct the study in accordance with this protocol, the 
Declaration of Helsinki and ICH GCP guidelines and FDA regulations.  The 
Investigator(s) and the Sponsor will sign the protocol and study contract, to confirm 
agreement.  The Investigator(s) will not implement any amendment (deviation or changes 
of the protocol) without agreement by the Sponsor and IRB/IEC approval, except where 
necessary to eliminate immediate hazard(s) to study subjects, or when change(s) involve 
only logistical or administrative aspects of the study. 
Records that may reveal the identities of subjects must be well protected, with 
consideration given to confidentiality and the right to privacy of subjects. 
Informed Consent 
Each subject or his/her parent/legal representative must be provided with a statement that 
the investigation involves research and that the IRB/IEC has approved solicitation of 
subjects to participate; a fair explanation of the procedures to be followed and their 
purposes, including identification of any procedures which are experimental; a 
description in lay language of any possible side effects; a description of any attendant 
discomforts and risks reasonably to be expected; a description of any benefits reasonably 
to be expected; a disclosure of any appropriate alternative procedures that might be 
advantageous for the subject; an offer to answer any inquiries concerning the procedures, 
and instruction that the person is free to withdraw consent and discontinue participation 
in the project or activity at any time without prejudice to the subject.  Payment to 
research subjects for participation in the study is considered a benefit.  All information 
concerning payment, including the schedule of payments, must be set forth in the 
informed consent, including a disclosure that the Investigator is being paid to perform the 
stated research. 
A subject (or the subject’s legally authorized representative) must give written consent to 
participate in the study.  This consent must be dated and retained by the Principal 
Investigator as part of the study records.  A copy shall be given to the person signing the 
form.  The informed consent process must be documented in the subject’s source 
documents. 
The Investigator agrees that the Sponsor, its employees or agents will have the right from 
time to time during the course of this study to audit and review pertinent medical records 
relating to this clinical trial.  A statement will be obtained from each subject participating 
in the study permitting the release of his/her medical records as necessary for inspection 
by authorized personnel of the Sponsor, FDA, other Competent Authorities and the staff 
managing the clinical study.  
The release of medical records and the review of the contents will be in compliance with 
the Health Insurance Portability and Accountability Act of 1996 (HIPAA and applicable 
data protection regulations in the countries concerned.

Institutional Review/Ethical Review 
The protocol and informed consent form for this study must be approved by an IRB/IEC.  
A copy of the Letter of Approval from the Board/Committee, which contains specific 
identification of the documents approved, must be received by the Sponsor prior to 
shipment of drug supplies to the Principal Investigator. 
All changes to the protocol, as well as a change of Principal Investigator, must also be 
approved by the Board/Committee and documentation of this approval provided to the 
study monitor.  Records of the IRB/IEC’s review and approval of all documents 
pertaining to the study must be kept on file by the Principal Investigator and are subject 
to FDA/Competent Authority inspection at any time.  IRB/IEC re-approval is required 
each year or according to local regulations.  The Principal Investigator is to notify the 
study monitor, in writing, of the approval to continue the study.   
Clinical Monitoring/Record Keeping 
There shall be no alterations in the protocol design without the written consent and 
approval of the Sponsor and the approval of the IRB/IEC, except in the case that subjects 
are at immediate risk without immediate implementation of such alterations.  In the 
aforementioned situation, the site should notify the Sponsor and IRB/IEC of the deviation 
as soon as possible, and should seek the written consent and approval of the Sponsor and 
the approval of the IRB/IEC. 
All results of this trial must be recorded on eCRFs.  Each subject who has been enrolled 
must have a completed eCRF.  Reasons for termination must be stated in the early 
termination section.  Study subjects are not to be identified by name on eCRFs, but rather 
by coded identifiers and subject initials.   
The study monitor will verify the accuracy of the data by reviewing pertinent source 
documents such as office records or hospital charts of the subjects. 
Study records include eCRFs, signed FDA Form 1572, original reports of test results, and 
signed informed consent forms.  IRB/IEC approval letters and other documents 
pertaining to the conduct of the study are to be kept on file by the Investigator.   If the 
study files are assigned to someone else or removed to another location, the Investigator 
is to notify the study monitor or Sponsor in writing of the change.  All study records are 
subject to FDA or Competent Authority inspection at any time. 
The Investigator shall retain records for a period as defined elsewhere (see Appendix C, 
Archiving of Study Documentation).   
All information supplied to the Investigator by the Sponsor before, during, and after the 
study is confidential.  Such information is to be used solely in connection with the 
clinical study.  The study protocol, IB, and any other pertinent study-related materials or 
records provided are to be maintained in a confidential manner, reviewed carefully with 
attention to admonitions and returned to the Sponsor upon request.  No part of these 
materials may be reproduced or transmitted in any form without prior written permission 
from the Sponsor.

CRITERIA FOR DIAGNOSES OF PREDIABETES AND 
DIABETES  
Reference: American Diabetes Association. Classification and diagnosis of diabetes. 
Sec. 2. In Standards of Medical Care in Diabetes—2016. Diabetes Care 
2016;39(Suppl. 1):S13–S22. 
The American Diabetes Association (ADA) standards for the diagnosis of prediabetes 
consider three different categories of prediabetes, based on measures fasting glucose, 
HbA1c, or 2-hour postprandial glucose during a 75-gram oral glucose tolerance test 
(GTT). For purposes of this study, however, the diagnosis of prediabetes will be limited 
to a single prediabetes category of impaired fasting glucose, as follows: 
Prediabetes is defined by a fasting glucose of ≥100 mg/dL (5.6 mmol/L) and 
<126 mg/dL (7.0 mmol/L) (after no caloric intake for at least 8 hours and in the absence 
of antihyperglycemic medications).   
ADA criteria for the diagnosis of diabetes will be used as follows. 
Diabetes Is Diagnosed by One of the Following Criteria: 
1. A fasting glucose of ≥126 mg/dL (7.0 mmol/L) after no caloric intake for at least 
8 hours 
 
 
 
 
 
OR 
2. A random plasma glucose ≥200 mg/dL (11.1 mmol/L) associated with classic diabetes 
symptoms:  increased urination, increased thirst and unexplained weight loss   
OR 
3. 2-hour post-glucose load plasma glucose ≥200 mg/dL (11.1 mmol/L) following oral 
ingestion of a 75-gram anhydrous glucose solution in water.  Note: Oral glucose 
tolerance testing is not necessary if the subject has a fasting glucose level of 
≥126 mg/dL. 
OR 
4. A1C ≥6.5% (48 mmol/mol). The test should be performed in a laboratory using a 
method that is National Glycohemoglobin Standardization Program (NGSP) certified 
and standardized to the Diabetes Control and Complications Trial (DCCT) assay. 
Note: In the absence of unequivocal hyperglycemia, results indicating diabetes should be 
confirmed by repeat testing using any of the above measures.

APPENDIX J 
CONCOMITANT MEDICATIONS PROHIBITED OR 
TO BE USED ONLY WITH PRIOR PERMISSION 
 
Table 9 through Table 17 provide examples of drugs that are PROHIBITED for 
concomitant use in COR-2012-01. Table 18 through Table 20 provide examples of drugs 
that REQUIRE PERMISSION from the study Medical Monitor prior to concomitant 
use.  
Drugs listed below are categorized into one drug-interaction category per drug; however, 
some drugs could have been categorized into multiple drug-interaction categories (e.g. 
dexamethasone is both a systemic corticosteroid and a strong CYP3A4 inducer). In such 
cases, the drug is categorized into the most restricted concomitant use category as 
applicable. 
Although an attempt was made to provide a comprehensive list of relevant medications 
that are believed to present a potential risk of clinically significant drug interaction with 
COR-003, the lists intentionally omit some medications that should not be used 
concomitantly with COR-003, since concomitant use is not expected (e.g. some 
chemotherapeutic agents), and the lists probably omit others unintentionally. 
Furthermore, these lists will evolve as new drugs come to market and more is learned 
about the pharmacology of COR-003 and other medications. Therefore, they should be 
regarded as a minimum set of excluded and precautioned concomitant medications.

Note on Drug-drug Interactions via CYP3A4 
COR-003 is a substrate and potent inhibitor of CYP3A4. Therefore, the following drug 
interactions may occur when COR-003 is co-administered with other drugs that interact 
with CYP3A4.  
• COR-003 may decrease the elimination of drugs metabolized by CYP3A4, 
thereby increasing their plasma concentrations. Increased exposure to these 
drugs may cause an increase or prolongation of their therapeutic and/or 
adverse effects. Concomitant use with COR-003 is prohibited for drugs 
known to present a risk of serious side effects with increased exposure 
(Table 15). 
• For other drugs that are metabolized by CYP3A4, monitoring of plasma 
concentrations is advised when possible. Clinical signs and symptoms 
associated with these drugs should be monitored, with dosage adjusted as 
needed. 
• Drugs that may significantly decrease or increase the plasma concentrations of 
COR-003 by induction or inhibition of CYP3A4 or by altering absorption are 
prohibited (Table 16). 
The following drug interaction checker may be useful. However, this checker will not 
supersede the protocol excluded medications lists nor the judgment of the Medical 
Monitor or delegate: http://reference.medscape.com/drug-interactionchecker
