Target subject population
Japanese patients with hyperlipidemia accompanied by hypertriglyceridemia (TG in the range 
150-499 mg/dL) aged 20 years and over.
Duration of treatment
52 weeks.
Investigational product, dosage and mode of administration
The following investigational product(s) will be used in this study.
∀
AZD0585 1 g soft gelatine capsules
All subjects will need to take 4 capsules from assigned bottle, once daily just after breakfast.
Statistical methods
Primary analyses will be carried out by analysis of covariance (ANCOVA) model including 
percent change from baseline in TG at Week 12 Endpoint as a response variable, treatment 
and baseline statin use as factors and baseline TG as a covariate.  The primary analysis will be 
carried out on full analysis set (FAS).

will be provided from the model.  P-values will be provided for comparison of AZD0585 each 
dose vs. placebo.
The primary objective of this study is to demonstrate the superiority of AZD0585 2 g and 4 g 
when compared with placebo using the percent change from baseline in TG to Week 12 as a 
primary efficacy variable.  In order to protect family wise error rate to be 5%, superiority of 
AZD0585 2 g vs. placebo and superiority of AZD0585 4 g vs. placebo will be tested based on 
Hochberg procedure using two-sided significance level of 0.05. If a p-value for each 
hypothesis is less than 0.05/2 = 0.025, the corresponding hypothesis claimed to be 
demonstrated. If both p-values are less than 0.05, then the both hypotheses are claimed to be 
demonstrated.

INTRODUCTION
1.1
Background and rationale for conducting this study
AZD0585 capsules (hereinafter referred to as AZD0585), which was developed by Omthera 
Pharmaceuticals, Inc., is a complex mixture of 1 g of omega-3 free fatty acid (FFA) derived 
from fish oils, and primarily composed of eicosapentaenoic acid (EPA: 
 
and docosahexaenoic acid (DHA: 
 Omega-3 fatty acids are well-known 
to lower serum triglycerides (TG) levels by reducing the amount of hepatic TG secretion and 
by enhancing the rate of TG clearance from circulation. In Japan, Epadel® (S300, S600, S900 
and capsules 300; hereinafter referred to as Epadel®) and Lotriga® granular capsule 2 g 
(hereinafter referred to as Lotriga®), drugs containing omega-3 fatty acid like AZD0585, are 
approved for the indication of hyperlipidemia.  Epadel is composed mostly of EPA ethyl ester
(EE) and Lotriga is composed of EPA EE and DHA EE.
AZD0585 was initially developed for an indication to enhance the remission of Crohn’s 
Disease (Investigational New Drug application No. 65,440). While investigating this 
indication in two large, placebo-controlled, randomised, double-blind, Phase III trials 
(AZD0585 Program in Crohn’s Disease [EPIC]-1 in Europe and Canada, and EPIC-2 in North 
America and Europe), it was recognized that AZD0585 lowered TG levels in patients with TG 
levels in the slightly elevated range.  Since then, in overseas AZD0585 has been clinically 
developed for the indication of hypertriglyceridemia.
AZD0585 containing omega-3 fatty acid as FFA, unlike the existing drugs containing omega-
3-acid EE, does not require hydrolysis at absorption from the small intestine to the systemic 
circulation, and provides favourable bioavailability regardless of taking meals containing fat. 
Actually, in the clinical pharmacology study of AZD0585 (ECLIPSE-2), the bioavailability of 
AZD0585 4 g per day and Lovaza®4 g per day administered up to 14 days with low-fat diet 
(evaluated by plasma total EPA, DHA and total1 EPA + total DHA levels) was significantly 
higher compared to Lovaza®, a drug containing omega-3-acid EE.
In two Phase III studies (EVOLVE (OM-EPA-003) and ESPRIT (OM-EPA-004)) conducted 
out of Japan, consistent dose-dependent TG-lowering response with AZD0585 treatment was 
observed and clinical benefit on improving lipid parameters was demonstrated in both studies.
In EVOLVE study conducted with severe hypertriglyceridemia, TG levels were between ≥500
mg/dL and <2000 mg/dL after a washout period of lipid-altering medications other than 
statins and ezetimibe, median baseline TG level was 694 mg/dL. Treatment with AZD0585 
led to statistically significant reductions in fasting TG levels (median % changes from baseline 
in TG were -10%, -25%, and -31% for placebo, AZD0585 2 g, and AZD0585 4 g, 
respectively; p<0.01 and p<0.001 for AZD0585 2 g and 4 g vs. placebo, respectively).

this study. Although placebo was extra virgin olive oil for both EVOLVE and ESPRIT 
studies, corn oil is used for placebo instead of extra virgin olive oil in this study, because it is 
reported that no statistically significant changes were observed in human plasma TG 
concentrations by corn oil and extra virgin olive oil (Sirtori et al 1986, Lichtenstein et al 1993).
This study is a randomised, double-blinded, placebo controlled, parallel group study designed 
to evaluate the efficacy of 12 weeks and safety of 52 weeks of AZD0585 treatment, 
respectively, in Japanese subjects with hyperlipidemia accompanied by hypertriglyceridemia 
(TG in the range 150-499 mg/dL). The effect of 2 g or 4 g dose of AZD0585 once daily 
on %TG reduction will be evaluated by comparing with that of 4 g dose of placebo (corn oil).  
In addition, a long-term safety of 2 g or 4 g dose of AZD0585 once daily will be evaluated by 
comparing with the placebo control in a double-blinded fashion so that the relationship 
between AZD0585 administration and AEs including abnormalities in safety parameters such 
as clinical laboratory test can be better assessed with some insights of AZD0585
dose-dependency on the AEs.
An interim analysis is planned in this study. The data of interim analysis will be cut off when
the last subject goes through Visit 11. An interim analysis will include all patients’ data 
available until data cut-off even if patients withdraw prior to Visit 11 including analysis at 
Week 12 Endpoint for primary efficacy endpoint as well as safety evaluation up to Visit 11.
1.3
Benefit/risk and ethical assessment
AZD0585 contains omega-3-acid as FFA and has an advantage of greater bioavailability over 
existing omega-3-acid EE alternatives because absorption of EEs is significantly dependent on 
stimulated intestinal hydrolysis (food-activated) for mucosal uptake (Ikeda et al 1995, Small 
1991, El Boustani et al 1987, Hazra et al 1999, Lawson and Hughes 1988a, Lawson and 
Hughes 1988b, Beckermann et al 1990, Hansen et al 1998).
The meal-fat independency of the AZD0585 formulation is important for full treatment effects, 
as patients with hypertriglyceridemia are advised to restrict fat intake in order to reduce TG 
and the associated risk of pancreatitis or CVD events (NCEP 2002).
The total intake of EPA plus DHA in subjects will not exceed 3 g per day since the planned 
4 g per day dose of AZD0585 contains approximately 75% EPA plus DHA.  This dose level is 
in agreement with the 1997 FDA ruling of 3 g per day as Generally Recognized as Safe for 
this aggregate amount (FDA 1997).  In a previous Phase I study with AZD0585 in healthy 
adult male Japanese subjects (D5881C00005), 4 g AZD0585 was safe and well tolerated 
following single- and multiple-dose and once-daily administration up to 14 days.
Additionally, AZD0585 4 g daily dose was safe and well tolerated for up to 3 years in subjects 
with Crohn’s disease. Therefore it is considered that 52-week treatment period is applicable 
for this study.

The patients who are allocated to placebo group continue placebo treatment for 52 weeks. 
From ethical point of view, patients are allowed to use lipid lowering drugs and/or 
supplements except for omega-3-acid after Visit 8.
1.4
Study Design
This is a randomised, double-blinded, placebo controlled, study employing 3 arm parallel 
groups to evaluate efficacy of 12 weeks and safety of 52 weeks of AZD0585 administration in 
patients with hyperlipidemia accompanied by hypertriglyceridemia (TG in the range 
150-499 mg/dL).
Total 375 subjects will be randomised to 3 cohorts, A) placebo, B) Epanova 2 g, and C) 
Epanova 4 g, at a ratio of 1:2:2, respectively.  The efficacy will be evaluated as placebo-
corrected percent change TG reduction at 12 weeks from the baseline TG level (see Section 
8.1).  The safety will be evaluated as AEs and other safety parameters (vital sign, clinical 
laboratory test, etc) during 52-week treatment period.

AstraZeneca staff and/or staff at the study site)
23.
Previous participation in a clinical study with AZD0585.
Procedures for withdrawal of incorrectly enrolled subjects see Section 3.4.
3.3
Subject enrolment and randomisation
The Principal Investigator (PI) will ensure:
1.
Signed informed consent is obtained from each potential subject before any study 
specific procedures are performed.
2.
The eligibility of each subject is determined see Sections 3.1 and 3.2.
3.
Each potential subject is assigned a unique enrolment number, beginning with “E”.
4.
Each eligible subject is assigned a unique randomisation code.
Randomisation will be performed before the first dose treatment at Visit 4.
Randomisation codes will be assigned strictly sequentially as subjects become eligible for 
randomisation.
If a subject withdraws his participation in the study, then his/her enrolment/randomisation 
code cannot be reused.
3.4
Procedures for handling incorrectly enrolled or randomised 
subjects
Subjects who fail to meet the eligibility criteria should not, under any circumstances, be 
enrolled or receive study medication.  There can be no exceptions to this rule.  Subjects who 
are enrolled, but subsequently found not to meet all the eligibility criteria must not be 
randomised or initiated on treatment, and must be withdrawn from the study.
Where a subject does not meet all the eligibility criteria but is randomised in error, or 
incorrectly started on treatment, the Investigators should inform the AstraZeneca Study Team
Physician immediately, and a discussion should occur between the AstraZeneca Study Team
Physician and the investigators regarding whether to continue or discontinue the patient from 

Clinical Study Protocol

treatment.  The AstraZeneca Study Team Physician must ensure all decisions are 
appropriately documented.
3.5
Methods for assigning treatment groups
Patients will be randomised to placebo, AZD0585 2g and AZD0585 4 g with the ratio of 1:2:2.
Randomisation will be stratified by concomitant statin use (yes / no) at baseline and baseline 
TG value (<300, ≥300 mg/dL).
Stratified randomisation will be conducted so that approximately 50% or more of total 
randomised patients are statin users.
3.6
Methods for ensuring blinding
The treatment allocation in this study will be double-blind. To ensure the blinding of the 
treatments, matching AZD0585 placebo capsules will be used. Each pack will be labelled 
with a unique kit ID number that will be used to assign the treatment to the patient but will not 
indicate treatment allocation to the investigators or patient.
An un-blinded interim report will be provided based on Visit 11 data, in order to submit Japan 
New Drug Application. Investigators and patients will be kept blinded to randomized 
treatment up-to study closure.
The plasma fatty acids profile (EPA, DHA, AA and EPA/AA ratio) data from Visit4 or later 
and the serum TG values between Visit4 and Visit8 will also be kept double-blinded until the 
interim database lock. These data will not be disclosed to Investigators and patients up-to 
study closure.
3.7
Methods for unblinding 
Individual treatment codes, indicating the treatment randomisation for each randomised 
subject, will be available to the Investigator(s) or pharmacists from the interactive voice 
response system (IVRS) / interactive web response system (IWRS). Routines for this will be 
described in the IVRS/IWRS user manual that will be provided to each site.
The treatment code should not be broken except in medical emergencies when the appropriate 
management of the subject requires knowledge of the treatment randomisation. The 
Investigators documents and reports the action to AstraZeneca, without revealing the 
treatment given to subject to the AstraZeneca representative.
AstraZeneca representatives who are independent to the study evaluation at the Patient Safety 
Department retains the right to break the code for serious adverse event (SAE) that are 
unexpected and are suspected to be causally related to an investigational product and that 
potentially require expedited reporting to regulatory authorities. Treatment codes will not be 
broken for the planned analyses of data until all decisions on the evaluability of the data from 
each individual subject have been made and documented.

after the nearest meal after study procedure of the study visit.
8.
Subjects must make every attempt to adhere to the dietary and physical activity 
changes and goals as discussed with the Investigator(s) during study period.
9.
Women of child-bearing potential must immediately contact the Investigators if 
they suspect they might be pregnant and if they have changed, or plan to change 
their birth control method during study period.
The sponsor or designee should be contacted if the investigator is informed of any restriction 
violations.  The sponsor will decide whether a subject with restriction violations will be 
allowed to continue study participation.
3.9
Discontinuation of investigational product
Subjects may be discontinued from investigational product in the following situations:
∀
Subject decision.  The subject is at any time free to discontinue treatment, without 
prejudice to further treatment

3.9.1
Procedures for discontinuation of a subject from investigational product
At any time, subjects are free to discontinue investigational product or withdraw from the 
study (i.e., investigational product and assessments – see Section 3.10), without prejudice to 
further treatment.  A subject that decides to discontinue investigational product will always be 
asked about the reason(s) and the presence of any AEs.  If possible, they will be seen and 
assessed by an Investigator(s).  AEs will be followed up (see Section 6); diary cards and all 
study drugs should be returned by the subject. If the patient discontinues the study during the 
treatment period (by Visit 18), the test and evaluations planned at Visit 18 should be 
performed unless the patient refuses the procedure.
If a subject is withdrawn from study, see Section 3.10.
3.10
Criteria for withdrawal 
Subjects may be withdrawn from the study in the following situations:
∀
Subject decision.  The subject is at any time free to withdraw from study
∀
AE
∀
Severe non-compliance with the study protocol, as judged by the investigator(s) or
AstraZeneca
∀
Incorrect enrolment of the patient
∀
Patient falls into exclusion criteria, e.g., pregnancy
∀
Death
∀
Patient lost to follow up
3.10.1
Screen failures 
Screening failures are patients who do not fulfil the eligibility criteria for the study, and 
therefore must not be randomised.  These patients should have the reason for study withdrawal 
recorded as ‘Incorrect Enrolment’ (i.e., patient does not meet the required inclusion/exclusion 
criteria).  This reason for study withdrawal is only valid for screen failures (not randomised
patients).
3.10.2
Withdrawal of the informed consent
Patients are free to withdraw from the study at any time (investigational product and 
assessments), without prejudice to further treatment.
A patient who withdraws consent will always be asked about the reason(s) and the presence of 
any AE.  The Investigators will follow up AEs outside of the clinical study. 
If a subject withdraws from participation in the study, then his/her enrolment/randomisation 
code cannot be reused. Withdrawn subjects will not be replaced.
If possible, they will be seen and assessed by investigators.  Unresolved AEs will be followed 
up (see Sections 6.3.2); investigational products should be returned by the subject.

4.1
Screening period
Investigator(s) should keep a record, the subject screening log, of subjects who entered pre-
study screening. Investigators will obtain signed informed consent from a potential subject
before starting screening period. Each subject should meet all of the inclusion criteria and 
none of the exclusion criteria for this study.  Under no circumstances can there be exceptions 
to this rule.
Screening period takes 8 weeks. Concomitant medications for hyperlipidemia except for 
statins are not allowed to use.
Subjects will take 3 study visits during screening period (Visit 1, Visit 2 and Visit 3). TG, 
LDL-C and other laboratory data will be measured at each visit, then only the subjects with 
TG and LDL-C values within acceptable ranges of variability will be randomised (see 
Sections 3.1).  In case repeat of Visit 3 test (Visit 3a) is performed between Visit 3 and 4 at 
investigators discretion, eligibility should be re-evaluated with using Visit 3a data (see Section 
3.1).
The following assessments and procedures should be performed during screening period as 
per Table 1.

5.2.2.2
Clinical Assessments
Subjects will be questioned by investigators at every visit regarding the occurrence and nature 
of any symptoms and signs. Body weight will be measured at each time, however, height will 
be measured only at Visit 1 to determine the BMI.
5.2.3
ECG
For timing of assessments refer to the Study Plan (Table 1).
A 12-lead ECG will be performed after patient has been supine at rest for at least 5 minutes.
All ECGs will be evaluated for heart rate, QT interval, ECG interval measured from the onset 
of the QRS complex to the onset of the P wave (PR), ECG interval measured from the onset of 
the QRS complex to the J point (QRS), and the time between corresponding points on 2 
consecutive R waves on ECG (RR) intervals from the 12-lead ECG, and the Investigators will 
judge the overall interpretation as normal or abnormal.  If abnormal, it will be decided as to 
whether or not the abnormality is clinically significant and the reason for the abnormality will 
be recorded. ECG will be measured using the same recording device during this study as 
much as possible.
All ECG readings will be stored as source documents as a paper printout if the data will not be 
able to kept electronically.

SAFETY REPORTING AND MEDICAL MANAGEMENT
The PI is responsible for ensuring that all staff involved in the study are familiar with the 
content of this section.

6.1
Definition of adverse events
An AE is the development of an undesirable medical condition or the deterioration of a pre-
existing medical condition following or during exposure to a pharmaceutical product, whether 
or not considered causally related to the product.  An undesirable medical condition can be 
symptoms (e.g., nausea, chest pain), signs (e.g., tachycardia, enlarged liver) or the abnormal 
results of an investigation (e.g., laboratory findings, ECG).  In clinical studies, an AE can 
include an undesirable medical condition occurring at any time, including screening periods, 
even if no study treatment has been administered.
The term AE is used to include both serious and non-serious AEs.
6.2
Definitions of serious adverse event
A SAE is an AE occurring during any study phase (i.e., screening and treatment), that fulfils 
one or more of the following criteria:
∀
Results in death
∀
Is immediately life-threatening
∀
Requires in-patient hospitalisation or prolongation of existing hospitalisation
∀
Results in persistent or significant disability/incapacity or substantial disruption of 
the ability to conduct normal life functions
∀
Is a congenital abnormality or birth defect
∀
Is an important medical event that may jeopardise the subject or may require 
medical intervention to prevent one of the outcomes listed above.
For further guidance on the definition of a SAE, see Appendix B to the Clinical Study 
Protocol.
6.3
Recording of adverse events
6.3.1
Time period for collection of adverse events
AEs will be collected from randomisation (Visit 4) until Visit 18 (or Visit 19).
SAEs will be recorded from the time of informed consent (Visit 1) until Visit 18 (or Visit 19).
6.3.2
Follow-up of unresolved adverse events
Any AEs that are unresolved at the subject’s last visit in the study are followed up by the 
investigator for as long as medically indicated, but without further recording in the eCRF.  
AstraZeneca retains the right to request additional information for any subject with ongoing 
AE(s)/SAE(s) at the end of the study, if judged necessary.
6.3.3
Variables 
The following variables will be collected for each AE:

Clinical Study Protocol

In addition, the following variables will be collected for SAEs:
∀

∀
Date Investgators became aware of serious AE
∀
AE is serious due to
∀
Date of hospitalisation
∀
Date of discharge
∀

Causality assessment in relation to Study procedure(s)
∀
Description of AE
Intensity rating scale:
1.
mild (awareness of sign or symptom, but easily tolerated)
2.
moderate (discomfort sufficient to cause interference with normal activities)
3.
severe (incapacitating, with inability to perform normal activities)
It is important to distinguish between serious and severe AEs.  Severity is a measure of 
intensity whereas seriousness is defined by the criteria in Section 6.2.  An AE of severe 
intensity need not necessarily be considered serious.  For example, nausea that persists for 
several hours may be considered severe nausea, but not a SAE unless it meets the criteria 
shown in Section 6.2. On the other hand, a stroke that results in only a limited degree of 
disability may be considered a mild stroke but would be a SAE when it satisfies the criteria 
shown in Section 6.2.
6.3.4
Causality collection
The PI will assess causal relationship between investigational product and each AE, and 
answer “yes” or “no” to the question “Do you consider that there is a reasonable possibility 
that the event may have been caused by the investigational product?”

Clinical Study Protocol
Drug Substance AZD0585
Study Code D5884C00002
Edition Number 1
Date 3 April 2015
38(52)
For SAEs causal relationship will also be assessed for other medication and study procedures.  
Note that for SAEs that could be associated with any study procedure the causal relationship is 
implied as “yes”.
A guide to the interpretation of the causality question is found in Appendix B to the Clinical 
Study Protocol.
6.3.5
Adverse events based on signs and symptoms
All AEs spontaneously reported by the subject or reported in response to the open question 
from the study personnel: “Have you had any health problems since you were last asked?”, or 
revealed by observation will be collected and recorded in the eCRF.  When collecting AEs, 
the recording of diagnoses are preferred (when possible) to recording a list of signs and 
symptoms.  However, if a diagnosis is known and there are other signs or symptoms that are 
not generally part of the diagnosis, the diagnosis and each sign or symptom will be recorded 
separately.
6.3.6
Adverse events based on examinations and tests
The results from protocol mandated laboratory tests, vital signs, ECGs and other safety 
assessments will be summarised in the clinical study report.  Deterioration as compared to 
baseline in protocol-mandated laboratory values, vital signs, ECGs and other safety 
assessments should therefore only be reported as AEs if they fulfil any of the SAE criteria or 
are the reason for discontinuation of treatment with the investigational product.
If deterioration in a laboratory value or vital sign is associated with clinical signs and 
symptoms, the sign or symptom will be reported as an AE and the associated laboratory result 
or vital sign will be considered as additional information.  Wherever possible the reporting 
investigator uses the clinical, rather than the laboratory term (e.g., anaemia versus low Hb 
value).  In the absence of clinical signs or symptoms, clinically relevant deteriorations in non-
mandated parameters should be reported as AE(s).
Any new or aggravated clinically relevant abnormal medical finding at a physical examination 
as compared with the baseline assessment will be reported as an AE.
6.4
Reporting of serious adverse events
All SAEs have to be reported, whether or not considered causally related to the investigational 
product, or to the study procedure(s).  All SAEs will be recorded in the eCRF.
If any SAE occurs in the course of the study, then investigators or other site personnel inform 
appropriate AstraZeneca representatives promptly, or no later than 24 hours of when he or 
she becomes aware of it.
The designated AstraZeneca representative works with the investigator to ensure that all the 
necessary information is provided to the AstraZeneca patient safety data entry site within one 
calendar day of initial receipt for fatal and life threatening events and within five calendar 
days of initial receipt for all other SAEs.

Clinical Study Protocol
Drug Substance AZD0585

39(52)
For fatal or life-threatening AEs where important or relevant information is missing, active 
follow-up is undertaken immediately.  Investigators or other site personnel inform 
AstraZeneca representatives of any follow-up information on a previously reported SAE 
promptly, or no later than 24 hours of when he or she becomes aware of it.
Once the investigator or other site personnel indicate an AE is serious in the WBDC system, 
an automated email alert is sent to the designated AstraZeneca representative.
If the WBDC system is not available, then the investigator or other study site personnel 
reports a SAE to the appropriate AstraZeneca representative by telephone.
The AstraZeneca representative will advise the investigator/study site personnel how to 
proceed.
6.5
Overdose
There are no human data on overdosing and no known antidote.
It will be considered the taking investigational product that is ≥ 5 capsules per day to be the 
overdose.
∀
An overdose with associated AEs is recorded as the AE diagnosis/symptoms on the 
relevant AE modules in the eCRF and on the Overdose eCRF module.
∀
An overdose without associated symptoms is only reported on the Overdose eCRF 
module.
If an overdose on an AstraZeneca study drug occurs in the course of the study, then the 
Investigator or other site personnel inform appropriate AstraZeneca representatives 
immediately, or no later than 24 hours of when he or she becomes aware of it.
The designated AstraZeneca representative works with the Investigator to ensure that all 
relevant information is provided to the AstraZeneca Patient Safety data entry site.
For overdoses associated with a SAE, the standard reporting timelines apply, see Section 6.4.  
For other overdoses, reporting must be provided to the AstraZeneca Patient Safety data entry 
site within 30 days.
6.6
Pregnancy
All pregnancies and outcomes of pregnancy should be reported to AstraZeneca.
6.6.1
Maternal exposure
If a subject becomes pregnant during the course of the study, investigational product should be 
discontinued immediately.
Pregnancy itself is not regarded as an AE unless there is a suspicion that the investigational 
product under study may have interfered with the effectiveness of a contraceptive medication.

Congenital abnormalities/birth defects and spontaneous miscarriages should be reported and 
handled as SAEs.  Elective abortions without complications should not be handled as AEs.  
The outcome of all pregnancies (spontaneous miscarriage, elective termination, ectopic 
pregnancy, normal birth or congenital abnormality) should be followed up and documented 
even if the subject was discontinued from the study.
If any pregnancy occurs in the course of the study, then the Investigator or other site personnel 
informs the appropriate AstraZeneca representatives promptly, or no later than 24 hours of 
when he or she becomes aware of it.
The designated AstraZeneca representative works with the Investigator to ensure that all 
relevant information is provided to the AstraZeneca Patient Safety data entry site within 1 or 5 
calendar days for SAEs (see Section 6.4) and within 30 days for all other pregnancies.
The same timelines apply when outcome information is available.
The PREGREP module in the eCRF is used to report the pregnancy and the PREGOUT is 
used to report the outcome of the pregnancy.
6.6.2
Paternal exposure
There are no restrictions against fathering a child when treated with AZD0585.
If paternal exposure pregnancy occurs in the course of the study, then investigators or other 
centre personnel should inform appropriate AstraZeneca representatives within 24 hours as 
described in the maternal exposure Section 6.6.1.

All personnel involved with the analysis of the study will remain blinded until 
database lock and protocol violators identified.
∀
Analyses will be performed by AstraZeneca or its representatives.
8.2
Sample size estimate
A common standard deviation of 24% is assumed for primary efficacy variable (percent 
change from baseline to Week 12 Endpoint in serum TG). One hundred and fifty patients in 
both of AZD0585 2 g and AZD0585 4 g and 75 patients in placebo will ensure the power for 
detecting 12.5% difference of AZD0585 each dose vs. placebo to be at least 92%, based on t-
test with two-sided significance level of 0.05/2= 0.025.
In the above calculation, it was assumed that a total of 375 patients are to be randomised to 
placebo, AZD0585 2 g, AZD0585 4 g with ratio of 1:2:2 and that proportion of randomised
patients not contributing primary analysis at Week 12 Endpoint is negligible.
In addition, the above sample size is expected to be sufficient to provide long term safety data 
of more than 100 Japanese patients treated by AZD0585 2 g or by AZD0585 4 g for 1 year.
8.3
Definitions of analysis sets
Randomised set: all patients who received randomisation number.
8.3.1
Efficacy analysis set
Full Analysis Set (FAS): all randomised set who had both any baseline and any post-baseline 
efficacy measurements.  Patients will be analyzed according to their randomised treatment.  
FAS will be considered primary analysis set used for all efficacy evaluation.
Per Protocol Set (PPS): all patients in FAS who completed the first 12-week treatment period 
without any significant protocol deviations affecting primary efficacy evaluations.  All criteria 
to exclude patients from the PPS will be made prior to the unblinding of the study. Patients 
will be analyzed according to their randomised treatment.  Analyses on PPS will be of 
supportive purpose and limited to primary and important secondary efficacy variables.
8.3.2
Safety analysis set
Safety set: all patients who took at least on dose of double-blind study medication. Patients 
will be analyzed according to actual medication received.

Methods for statistical analyses
8.5.1
Analysis of the primary variable (s)
Primary analyses will be carried out by analysis of covariance (ANCOVA) model including 
percent change from baseline in TG at Week 12 Endpoint as a response variable, treatment 
and baseline statin use as factors and baseline TG as a covariate. The primary analysis will be 
carried out on FAS.

Least square means and 95%CI for each treatment as well as treatment difference to placebo 
will be provided from the model. P-values will be provided for comparison of AZD0585 each 
dose vs. placebo.
As a sensitivity analysis, log-transformed TG at Week 12 Endpoint will also be analyzed by 
ANCOVA model including treatment and baseline statin use as factors and log-transformed 
baseline TG as a covariate.  Least square means and 95%CI for treatment difference to 
placebo will be back transformed and presented as relative treatment difference to placebo in 
percent change from baseline of TG.
Definition of Endpoint and baseline & missing values
Baseline is defined as average of Week -4, -2 and 0.
Week 12 Endpoint is defined as an average of measurements Week 10 and Week 12. 
If patients drop out before Week 12, average of the last two consecutive post-treatment values 
will be used for Week 12 Endpoint evaluation. If only one post-baseline measurement is 
available, it will be employed for Endpoint evaluation.  Data obtained after Week 12 visit will 
not be used for evaluation of Week 12 Endpoint. 
It is assumed that most patients will complete 12-week treatment without major deviations and 
the above approach would provide approximately unbiased estimates for treatment effects. 
However, further sensitivity checks may be planned and documented in Statistical Analysis 
Plan.
Confirmatory Hypothesis Family & Multiplicity
The primary objective of this study is to demonstrate the efficacy of AZD0585 2 g and 4 g 
when compared with placebo using the percent change from baseline in TG to Week 12 as a 
primary efficacy variable. In order to protect family wise error rate to be 5%, superiority of 
AZD0585 2 g vs. placebo and superiority of AZD0585 4 g vs. placebo will be tested based on 
Hochberg procedure using two-sided significance level of 0.05. If a p-value for each 
hypothesis is less than 0.05/2 = 0.025, the corresponding hypothesis claimed to be 
demonstrated. If both p-values are less than 0.05, then the both hypotheses are claimed to be 
demonstrated.
All analyses other than analysis of the primary efficacy endpoint will be interpreted 
descriptively. Consequently, no adjustments for multiplicity will be necessary for such 
analyses. Ninety-five percent confidence intervals will be calculated, where appropriate, as 
measures of study precision. P-values may be calculated but are to be regarded as descriptive.
