Objectives 
Primary objectives. 
Part A. Safety run-in:  
To assess the safety and tolerability of two schedules of AZD5363 (continuous and 
intermittent dosing) when combined with weekly paclitaxel in patients with advanced or 
metastatic breast cancer; and to recommend, by assessment of dose limiting toxicities and 
other safety, tolerability, pharmacokinetic and pharmacodynamic data, a dose and schedule of 
AZD5363 for further study when combined with weekly paclitaxel. 
Part B. Randomised expansion:  
To assess the relative anti-tumour activity of AZD5363 when combined with weekly 
paclitaxel vs. weekly paclitaxel plus placebo by comparison of change in tumour size at 12 
weeks (target lesion assessment using RECIST 1.1) in the overall advanced or metastatic 
Estrogen Receptor positive breast cancer population and in a Phosphoinositide 3-kinase 
(PIK3CA) mutation-positive sub-population. 
Secondary objectives (summarised) 
Part A. Safety run-in: 
To make a preliminary assessment of the anti-tumour activity of AZD5363 when combined 
with paclitaxel.  
Part B. Randomised expansion: 
x
To assess the relative efficacy of AZD5363 when combined with weekly paclitaxel 
compared with weekly paclitaxel plus placebo. 
x
To assess the safety and tolerability of AZD5363 when combined with weekly 
paclitaxel compared with weekly paclitaxel plus placebo.  
x
To investigate the effect on patients’ quality of life of AZD5363 when combined 
with weekly paclitaxel, compared with weekly paclitaxel plus placebo.

x
To assess the pharmacokinetics of paclitaxel alone and when combined with 
AZD5363. 
x
To assess the pharmacokinetic/pharmacodynamic relationship between AZD5363 
exposure and biomarkers in blood and anti-tumour activity.

Study design 
This international, multicentre, study of AZD5363 when combined with paclitaxel vs 
paclitaxel plus placebo will be conducted in two parts:   
Part A: Safety Run-in.   
An open-label run-in to assess the comparative safety, tolerability pharmacokinetics and 
pharmacodynamics of ascending doses of AZD5363 in two schedules (continuous and 
intermittent dosing) when combined with weekly paclitaxel; and to make a preliminary 
assessment of the anti-tumour activity of the combination. 
The primary output of Part A will be a recommended dose and schedule of AZD5363 when 
combined with paclitaxel for conduct of the study Part B randomised expansion phase.    
AZD5363 and paclitaxel will be given in the dosing schedules detailed below.  Cohorts of 3 to 
6 patients will be evaluated in escalating doses of AZD5363 to determine a recommended 
dose and, where applicable, a maximum tolerated dose for each schedule. 
Patient assessments will continue up to cessation of both AZD5363 and paclitaxel or 
withdrawal of consent or death.  A 28-day safety follow-up assessment should be conducted 
following cessation of all study therapy (AZD5363 and paclitaxel). 
Part A: Safety run-in - Subsidiary Japanese patient evaluation (optional) 
A subsidiary dose-escalating safety evaluation may optionally be conducted in a 
Japanese patient population at a starting dose, and under one schedule, determined by 
the Safety Review Committee.  This evaluation would be conducted to determine a 
safe and tolerable dose of AZD5363 when combined with weekly paclitaxel in a 
Japanese population. 
This separate Japanese safety run-in evaluation would commence following 
determination of the RD and dosing schedule in the Western population.  It would 
proceed in parallel with the Part B randomised expansion, but would not inform any 
decision regarding the conduct of Part B.  The schedule of assessments in the 
subsidiary Part A would be as detailed in this protocol for Part A.  It is not envisaged 
that a Japanese population would be evaluated under study Part B. 
Part B: Randomised Expansion 
A randomised double-blind assessment of the safety, tolerability, pharmacokinetics, 
pharmacodynamics and anti-tumour activity of the dose and schedule of AZD5363 selected 
from Part A when combined with weekly paclitaxel - versus weekly paclitaxel plus placebo 
matched to AZD5363.  
AZD5363/placebo and paclitaxel will be given in either the continuous or intermittent dosing 
schedule detailed below.   
Patients will be assessed at screening for presence/absence of PIK3CA tumour mutations and 
will be stratified in to PIK3CA mutation-positive and PIK3CA mutation-not detected arms. 
Within each stratum, patients will be randomised to receive either paclitaxel plus AZD5363 or 
paclitaxel plus placebo.

Target patient population 
Part A. Safety run-in: Female patients, 18 years or older, with advanced or metastatic breast 
cancer. 
Part B. Randomised expansion:  Female patients, 18 years or older, with ER+ve advanced or 
metastatic breast cancer.  For inclusion in Part B, patients must not have received any prior 
chemotherapy in the advanced or metastatic settings.  
Investigational product, dosage and mode of administration 
AZD5363: A twice daily regimen of an oral capsule formulation given on a continuous or 
intermittent weekly dosing schedule.  Administration of AZD5363 will commence in Part A 
as detailed in section 5.5.3: 
x
Continuous dosing: 320 mg bd (640 mg daily) throughout a patient’s participation 
in the study. 
x
Intermittent dosing (4 days of treatment followed by 3 days off-treatment): 360 mg 
bd (720 mg daily) each week that paclitaxel is received, and then each week 
following cessation of paclitaxel throughout a patient’s participation in the study. 
Placebo (Part B only): Oral capsule formulation, matched to AZD5363. 
Comparator, dosage and mode of administration 
Paclitaxel: A weekly single intravenous infusion of 90 mg/m2 given over approximately one 
hour.  A 28-day treatment cycle to comprise three consecutive weeks of treatment, followed 
by one week off-treatment. 
Duration of treatment 
Patients may receive study treatment, AZD5363/placebo and/or paclitaxel, to objective 
disease progression or withdrawal from study participation.  It is anticipated that 
approximately 6 cycles of paclitaxel therapy will be given in the absence of disease 
progression or unacceptable toxicity; but further cycles can be continued at an investigator’s 
discretion based on the patient’s risk/benefit profile.   
Outcome variable(s):  
To meet the objectives for this study, data for the following endpoints will be collected: 
Parts A and B: 
x
Safety and Tolerability. 
x
Tumour response as assessed by RECIST 1.1. 
x
AZD5363 and paclitaxel pharmacokinetics.

INTRODUCTION 
1.1 
Background 
1.1.1 
Investigational agent 
AZD5363 is a potent, selective inhibitor of the kinase activity of the serine/threonine 
AKT/PKB (protein kinase B) that is being developed as a potential treatment for solid and 
haematological malignancies. 
AKT is part of the AGC family of kinases.  Mammalian cells express three closely related 
AKT isoforms: AKT1 (PKBĮ), AKT2 (PKBȕ) and AKT3 (PKBȖ), all encoded by different 
genes.  AKT is a node of multiple signalling pathways promoting tumorigenesis, inhibiting 
apoptosis, impacting on cell cycle and promoting invasion and migration. 
The Phosphoinositide 3-kinase (PI3K)/AKT/Phosphatase and Tension Homolog (PTEN) 
pathway is frequently deregulated in cancer and drives tumour growth and cell survival 
(Lindsley 2010).  All 3 AKT isoforms are activated in different tumour types including breast, 
prostate, ovarian, pancreatic and gastric cancers, and this activation is often associated with 
resistance to established cancer therapies as well as advanced disease and/or poor prognosis 
(Altomere and Testa 2005). AKT activation in tumours is largely due to input from other 
signalling pathways upstream of AKT (eg, mutation of oncogenes such as Ras, Bcr-abl, 
mutation of receptor tyrosine kinases such as EGFR, amplification of Her2, loss of PTEN 
function, mutations of PI3K). 
Inhibitors of AKT are anticipated to have efficacy when dosed when combined with cytotoxic 
chemotherapies or when combined with targeted or antihormonal agents.  AZD5363 inhibits 
all three AKT isoforms (AKT1, AKT2 and AKT3) and therefore has the potential to provide 
clinical benefit over a range of therapeutic indications. 
A significant relationship has been found in pre-clinical studies between the presence of a 
phosphoinositide-3-kinase, catalytic, alpha polypeptide (PIK3CA) mutation and sensitivity to 
monotherapy AZD5363 in a panel of 182 cancer cell lines (p = 0.0059; T test).  Mutations in 
PIK3CA are common in human breast cancer; 27% of breast cancers harbour PIK3CA 
mutations.  They are most common in Estrogen receptor–positive (ER+) breast tumours (35% 
have PIK3CA mutations).  However, the relationship between PIK3CA mutation and 
sensitivity to AZD5363 is not absolute; some PIK3CA mutation-negative cell lines are also 
sensitive to AZD5363. 
1.1.2 
Non-clinical information and correlative studies 
AZD5363 is a potent inhibitor of AKT 1, 2 and 3 in enzyme assays and inhibits the 
phosphorylation of AKT substrates in cells.  AZD5363 inhibits the proliferation of a range of 
cell lines derived from solid and haematological tumours.  Breast cancer cell lines appear to 
be the tumour types that show the greatest sensitivity to AZD5363.  AZD5363 shows dose 
dependent pharmacodynamic and antitumour activity in xenografts at well-tolerated doses,

populations with advanced solid malignancies, under two separate AZD5363 monotherapy 
dosing regimens:  
x
continuous dosing at 80 mg bd (n=8), 160 mg bd (n=5), 240 mg bd (n=12), 400 mg 
bd (n=8) and 600 mg (n=2) 
x
intermittent dosing (4 days on and 3 days off) at 480 mg bd (n=5) and 640 mg bd 
(n=6) 
The most commonly reported Adverse Events (AEs), regardless of dose or causality, to date 
are: diarrhoea, hyperglycaemia, fatigue, maculo-papular rash, vomiting, dyspnoea, and 
nausea.  The majority of AEs reported in patients receiving AZD5363 have been Common 
Terminology Criteria for Adverse Events (CTCAE) Grade 1 or Grade 2 in toxicity. 
Common Terminology Criteria (CTC) Grades 3 and 4 adverse events have been associated 
with the use of AZD5363 in Study D3610C00001 as follows: 
x
diarrhoea: CTCAE grade 3 in the continuous dosing at 240 mg bd (n=1), 400 mg bd 
(n=1), 600 mg bd (n=1) and intermittent dosing (4 days on and 3 days off) at 640 
mg bd (n=2) 
x
hyperglycaemia (post AZD5363 dose), CTCAE grade 3 in the continuous dosing at 
240 mg bd (n=1), 400 mg bd (n=2) and intermittent dosing (4 days on and 3 days 
off) at 480 mg bd (n=1), 640 mg bd (n=4) 
x
maculo-papular rash: CTCAE grade 3 in the continuous dosing at 400 mg bd (n=1) 
and  CTCAE grade 4 in the continuous dosing at 600 mg bd (n=2) 
One dose-limiting toxicity (DLT) of CTCAE grade 3 hypoxia has been reported in a female 
patient with sarcoma with lung metastasis in study D3610C00004 under a continuous dosing 
schedule at a 240 mg bd dose.  
There has been a trend for an increase in plasma glucose levels approximately 2 hours after 
AZD5363 dosing (single and continuous dosing), generally returning to baseline levels within 
4 hours to 8 hours after AZD5363 dosing.  Plasma glucose elevations have been more 
pronounced in the higher dose levels. 
There have been no clinically significant findings identified on review of Electrocardiograms 
(ECGs) or left ventricular ejection fraction (LVEF) decreases attributed to AZD5363. 
One female patient with cervical carcinoma (PIK3CA mutation positive) with metastasis to 
the lymph nodes, receiving 400 mg bd in the continuous dosing regimen, had a confirmed 
partial response for 20 weeks prior to disease progression.  The patient had previously 
received adjuvant and first-line chemotherapy and radiation.

deaths from breast cancer has continued to rise in Europe (130,000 in 2004 vs 132,000 in 
2006) (Ferlay et al 2007).  In the US, breast cancer is the most common cancer in women with 
an incidence rate of 123.6 per 100,000 from 2001 to 2005.     
The treatment of breast cancer is determined by the extent of the disease and a variety of other 
prognostic factors, including hormone receptor status.  The most important factor determining 
response to hormonal manipulation is the presence of the ER in the target tissue (Fisher et al 
2001).  The choice of treatment sequence is complex and dependent on a number of factors, 
including prior endocrine treatments received.  Irrespective of the treatment sequence received 
a number of patients will experience disease progression, and therefore there remains a need 
to identify further treatment options for those patients who progress on or shortly after 
endocrine therapy. 
1.3.2 
Rationale for AZD5363 in breast cancer. 
AZD5363 has been shown to greatly increase sensitivity to the taxane docetaxel (Taxotere) in 
several breast cancer xenograft models.  For example, both continuous and intermittent 
schedules of AZD5363 enhanced the efficacy of docetaxel in the HCC-1187 xenograft () 
Figure 1).  The sequence of administration appears to be very important; in the HCC-1187 
model, administering docetaxel after an intermittent dosing schedule of AZD5363 (4 days on, 
3 days off) was found to be antagonistic, whilst administering docetaxel before the 
intermittent schedule resulted in enhanced efficacy (Figure 2)

The frequency of PIK3CA mutations in samples has been studied performing a mutational 
analysis of exons 9 (HD) and 20 (KD) of the PIK3CA gene using tumour deoxyribonucleic 
acid (DNA) obtained from patients with recurrent disease. Mutations in PIK3CA were 
identified in 24.5% of patients (11.3% in HD and 13.2% in KD). PIK3CA mutation was 
significantly correlated with lower tumour grade (47% in grade 1/2 vs 8% in grade 3, 
p=0.004), positive ER (35% in ER+ vs 5% in ER-, p=0.017), and PR (37% in PR+ vs 5% in 
PR-, p=0.011). Overall survival (OS) was 139.5 and 53.7 months for mutation and non-
mutation carriers respectively (p=0.014). (Ma et al 2009). 
Future treatment strategies may be aligned to the presence or absence of PIK3CA mutations. 
The presence of a PIK3CA mutation is correlated with sensitivity to monotherapy AKT 
inhibition (Courtney et al 2010) – and it is therefore considered appropriate to explore 
AZD5363 in this setting for patients in this population.  
1.3.4 
Rationale for study design. 
Pre-clinical data has shown that AZD5363 when given in combination with docetaxel is 
efficacious.  This study will test the hypothesis that this pre-clinical finding is applicable to 
paclitaxel in the clinical setting, utilising the following design: 
Part A. Safety run-in: to identify an appropriate and tolerable dose of AZD5363 and dosing 
schedule (continuous or intermittent), when in combination with weekly paclitaxel, to take 
forward to Part B.  
Part B. Randomised Expansion: to make an assessment of efficacy of the combination 
(paclitaxel plus AZD5363) against an active control (paclitaxel alone) in a specific target 
patient population (ER+ve breast cancer) and to explore whether additional efficacy is likely 
to be present in a PIK3CA mutation-positive sub-group for whom it is hypothesised that there 
will be greater sensitivity to AZD5363.  
1.3.5 
Rationale for Paclitaxel as combination therapy. 
Chemotherapy remains the mainstay of treatment in metastatic breast cancer (MBC) and the 
goals in this setting are to prolong survival, alleviate or prevent tumour-related symptoms and 
improve Quality of Life. 
The taxanes, specifically paclitaxel and docetaxel, are amongst the most active agents in MBC 
(Ghersi et al 2005) and have demonstrated significant activity in MBC in terms of response 
rate (RR) and progression free survival (PFS) (Beslija et al 2009). 
In current clinical practice, paclitaxel is used in doses ranging from 135 to 225 mg/m2 
administered every 3 weeks; however, its weekly administration usually at a dose of 80 mg/m2 
provides superior RR, PFS and overall survival (OS) (Seidman et al 2008). 
The toxicity profile of paclitaxel seems to be both dose and schedule dependent.  Various 
dosages and schedules of paclitaxel have been investigated in patients relapsing or failing after 
previous therapy combinations.  The issue of schedule-dependent activity was addressed in 
several studies.  In a phase I dose-finding study, 90 mg/m2 was found to be the optimal dose in

All patients should avoid concomitant use of drugs, herbal supplements and/or ingestion of 
foods known to potently modulate CYP3A4 enzyme activity from the time they enter the 
screening period until 2 weeks after the last dose of study treatment.   
All patients should avoid concomitant use of drugs and herbal supplements known to be 
CYP3A4 or CYP2D6 substrates from the time they enter the screening period until 2 weeks 
after the last dose of study treatment wherever possible.  If co-administration is necessary then 
additional monitoring for signs of toxicity related to increased exposure to the substrates is 
required. 
In addition, should AZD5363 pharmacokinetic outlying data be observed in the absence of 
confounding concomitant medications, patient genetic samples will be requested 
 
1.4.3 
Potential risks identified from early clinical studies with AZD5363: 
To date, the most commonly reported AEs, regardless of dose or causality, are: diarrhoea, 
hyperglycaemia, fatigue, maculo-papular rash, vomiting, dyspnoea and nausea. The majority 
of AEs reported in patients receiving AZD5363 have been CTCAE Grade 1 or Grade 2 in 
toxicity.  
Three (DLTs) of maculo-papular rash have been reported in study D3610C00001 under a 
continuous dosing schedule: one in a 400 mg bd cohort (CTCAE grade 3) and two in a 600 
mg bd cohort (CTCAE grade 4). 
Five AEs of diarrhoea: CTCAE grade 3 in the continuous dosing at 240 mg bd (n=1), 400 mg 
bd (n=1), 600 mg bd (n=1) and intermittent dosing (4 days on and 3 days off) at 640 mg bd 
(n=2) 
Seven AEs of  hyperglycaemia (post AZD5363 dose), CTCAE grade 3 in the continuous 
dosing at 400 mg bd (n=2) and intermittent dosing (4 days on and 3 days off) at 480 mg bd 
(n=1), 640 mg bd (n=4) 
1.4.4 
Risk minimisation activities for potential risks identified in early clinical 
studies with AZD5363: 
Glucose homeostasis  
In order to reduce the potential risk of exacerbating abnormal glucose profiles, patients with 
Type I or Type II diabetes mellitus (irrespective of management), fasting glucose 7 mmol/L 
or glycosyated haemoglobin (HbA1c) 8% at screening will be excluded from clinical studies 
with AZD5363.  Glucose, insulin and insulin C-peptide profiles will be performed on the first 
dosing day and at steady state during the first treatment cycle, at the start of each subsequent 
cycle and on discontinuation of AZD5363/placebo.  During the first cycle, urinary glucose 
will be tested twice weekly after patients are discharged from the clinic, with instructions 
regarding clinic contact on finding a high result.  Random blood glucose pre- and post-
AZD5363/placebo dosing will be monitored on planned study visit days and when needed to 
evaluate any episodes of hyperglycaemia.  In addition, because of the pharmacological 

Clinical Study Protocol

32(131) 
activity of AZD5363 on glycolysis and insulin signalling, fasting lipid profiles (triglycerides, 
high density lipoprotein (HDL), low density lipoprotein (LDL) and cholesterol) will also be 
monitored at baseline, every 12 weeks and at discontinuation of AZD5363/placebo.  A blood 
glucose intervention algorithm will be provided separately to this protocol to aid investigator 
management of elevated blood glucose. 
Diarrhoea 
There are no standard exclusion criteria for patients with diarrhoea; however, patients with 
previous gastrointestinal surgery that may affect drug absorption are excluded from AZD5363 
clinical studies.  Diarrhoea can be managed with treatment and interruptions to AZD5363 
dosing.  Patient reports of diarrhoea are expected to be evaluated and treated by investigators 
according to local practice (eg, use of medications such as loperamide, need for IV fluid 
replacement).  A toxicity management algorithm will be provided separately to this protocol 
to aid investigator management of diarrhoea. 
Rash 
There are no standard exclusion criteria for patients with rash.  Rash can be managed with 
treatment and interruptions to AZD5363/placebo dosing.  Patient reports of rash are expected 
to be evaluated and treated by investigators according to local practice (eg, use of oral or 
topical steroids, use of oral antihistamine).  A toxicity management algorithm will be provided 
separately to this protocol to aid investigator management of rash. 
1.4.5 
Overall benefit-risk and ethical assessment 
Although there can be no certainty of clinical benefit to patients, non-clinical data with 
AZD5363 support the hypothesis that AKT inhibition may be a valid target for the treatment 
of breast cancers with or without PIK3CA mutation.  The non-clinical safety profile and 
emerging clinical profile from the early clinical studies have not identified risks that would 
preclude investigation in this setting.  The study design aims to minimise potential risks, via 
confirmation of the optimum combination dose prior to the main randomised study.  A dose 
modification strategy for management of toxicity and monitoring is in place for those risks 
deemed to be most likely or serious.  Thus the benefit/risk assessment for this study supports 
the co-administration of AZD5363 with paclitaxel in patients with advanced or metastatic 
breast cancer with or without PIK3CA mutation.

STUDY PLAN AND PROCEDURES 
This Clinical Study Protocol has been subject to a peer review according to AstraZeneca 
standard procedures. 
3.1 
Overall study design and flow chart 
This international, multicentre study of AZD5363 when combined with paclitaxel will be 
conducted in two Parts- A and B: 
3.1.1 
Part A: Safety run-in   
A multiple ascending-dose evaluation of AZD5363 in each of two schedules (continuous and 
intermittent dosing) when combined with weekly paclitaxel.  These dose escalation schedules 
may commence at the same time, or one schedule may be inititiated in advance of the other to 
facilitate ease of study initiation.    
This part will assess the comparative safety, tolerability, pharmacokinetics and preliminary 
anti-tumour activity of both schedules of AZD5363 when combined with weekly paclitaxel.  
A recommended dose and schedule of AZD5363 will be determined for conduct of Part B, the 
randomised expansion (see section 3.1.2)    
The patient population will be female, aged 18 years or older, with advanced or metastatic 
breast cancer.  For inclusion in Part A, patients must not have received any more than two 
prior courses of chemotherapy for breast cancer.  Prior endocrine therapy is allowed. 

Clinical Study Protocol 
Drug Substance AZD5363  
Study Code D3610C00002 
Edition Number 1 
Date 24 February 2012 
35(131) 
Patients will be recruited in approximately 8 centres in approximately 4 countries.  The 
number of patients enrolled will be dependent upon the number of dose escalation cohorts 
required, see below, but a total of approximately 40 patients is anticipated.   
Both schedules of AZD5363 will be in combination with 90 mg/m2 paclitaxel (see section 
5.5.3):  
x
Continuous dosing:  AZD5363 capsules taken orally, twice daily, each day.  The 
starting dose for cohort 1 will be 320 mg (640 mg daily). 
x
Intermittent dosing:  AZD5363 capsules taken orally, twice daily, for repeating 
weekly cycles of 4 days on treatment followed by 3 days off treatment during each 
week that paclitaxel is received.  The starting dose for cohort 1 will be 360 mg (720 
mg daily).   
Dose escalating cohorts of 3 to 6 patients will be evaluated under each schedule.  A total of 6 
patients must be evaluated at a selected dose level for it to be confirmed as the RD.  AZD5363 
dose escalations and maximum doses attained will not exceed levels deemed tolerated by the 
Safety Review Committee (SRC) in prior first time in patient study D3610C00001. 
The RD for a schedule may or may not be defined by attainment of non-tolerated dose / 
maximum tolerated dose (NTD / MTD) levels (see section 5.10.2).  If the RD is selected prior 
to attaining MTD, the SRC will determine whether continued dose escalations to NTD/MTD 
are required.

Subsidiary Japanese patient evaluation (optional) 
A Part A subsidiary dose-escalating safety evaluation may be conducted optionally in a 
Japanese patient population at a starting dose, and under one schedule, determined by the 
Safety Review Committee.  This evaluation would be conducted to determine a safe and 
tolerable dose of AZD5363 when in combination with paclitaxel in a Japanese population. 
This separate Japanese safety run-in evaluation would commence following determination of 
the RD and dosing schedule in the Western population.  It would proceed in parallel with the 
Part B randomised expansion, but would not inform any decision regarding the conduct of 
Part B.  The schedule of assessments in the subsidiary Part A would be as detailed in this 
protocol for Part A.  It is not envisaged that a Japanese population would be evaluated under 
study Part B. 
3.1.2 
Part B: Randomised expansion 
A double-blind, stratified and randomised evaluation of AZD5363 when combined with 
weekly paclitaxel vs. weekly paclitaxel plus placebo.  The dose and schedule of AZD5363 
will be selected as an outcome from Safety run-in Part A.

Drug Substance AZD5363  
Study Code D3610C00002 
Edition Number 1 
Date 24 February 2012 
37(131) 
The patient population will be female, aged 18 years or older, with ER+ve advanced or 
metastatic breast cancer, and incorporating a subgroup who have PIK3CA mutation-positive 
tumour(s).  For inclusion in Part B, patients must not have received any prior chemotherapy 
for breast cancer in the advanced or metastatic setting.  Prior (neo)adjuvant chemotherapy is 
allowed (if (neo) adjuvant taxane, there must have been a minimum of 12 months from 
completion of therapy to relapse). 
Patients will be recruited in approximately 12 centres in approximately 5 countries.  
Approximately 70 patients will be enrolled in this phase (to ensure that 60 are evaluable at 12 
weeks), of which approximately 35 must have a tumour detectable as carrying a PIK3CA 
mutation.   
To be considered evaluable for the randomised expansion primary efficacy analysis, a 
patient must have baseline and week 12 (r1 week) tumour measurements for 
assessment of the primary endpoint of change in tumour size, or evidence of objective 
progression prior to week 12, or in the absence of week 12 measurements and no 
evidence of objective progression, RECIST measurements available at baseline and 1 
visit before or after week 12 such that a prediction for the week 12 result can be made 
(see section 11.1.1 for details).  An overage of approximately 15% of patients is 
therefore planned to be randomised to allow for potential non-evaluable patients. 
Patients will be stratified to PIK3CA mutation ‘positive’ and ‘not detected’ groups by 
prospective analysis of blood and/or tumour tissue (see sections 5.2 and 6.2.1).  Patients 
within each stratum will be randomised to 28-day cycles (see section 5.5.3) comprising either 
of: 
o Paclitaxel 90 mg/m2 IV once weekly plus AZD5363 capsules taken orally, 
twice daily. 
o Paclitaxel 90 mg/m2 IV once weekly plus AZD5363-matching placebo capsules 
taken orally, twice daily.

5. 
STUDY CONDUCT 
5.1 
Restrictions during the study 
The following restrictions apply while the patient is receiving study treatment and for the 
specified times before and after: 
1. 
Patients who are blood donors should not donate blood during the study and for 3 
months following their last dose of study treatment. 
2. 
Patients to avoid excessive sun exposure and use adequate screening protection.  
The use of sun-beds and tanning booths should be avoided.

Drug Substance AZD5363  
Study Code D3610C00002 
Edition Number 1 
Date 24 February 2012 
53(131) 
3. 
On PK sampling days in the clinic, patients must fast (water to drink only) from at 
least 2 hours prior to a dose of study therapy to at least 1 hour post-dose. On all 
other study days patients are requested to keep to these fasting restrictions wherever 
possible. 
4. 
On blood glucose assessment days (incorporating Clinical chemistry and 
glucose/insulin/insulin c-peptide) evaluations it is requested that patients refrain 
from calorific intake for a minimum of 8 hours prior to the morning dose of 
AZD5363 / placebo. 
5. 
Females of child-bearing potential should use two forms of highly reliable methods 
of contraception from the time of screening until 4 weeks after discontinuing study 
treatment.  Acceptable methods of contraception include: 

Established use of oral, injected or implanted hormonal methods of 
contraception. 

Placement of an intrauterine device or intrauterine system. 

Barrier methods of contraception: condom or occlusive cap (diaphragm or 
cervical/vault caps) with spermicidal foam/gel/film/cream/suppository. 

Male partner sterilisation (with the appropriate post-vasectomy documentation 
of the absence of sperm in the ejaculate). 

True abstinence.  
It is not known whether AZD5363 has the capacity to affect the metabolism of 
hormonal contraceptives, so hormonal contraception should also be combined with a 
barrier method of contraception. 
6. 
During Cycle 1, following discharge from the clinic, patients will be required to 
carry out a urine glucose assessment by dipstick prior to breakfast two times per 
week.  If a positive result is observed they must contact the clinic for further 
investigation of this result. 
5.2 
Patient enrolment, randomisation and initiation of investigational 
product 
The Principal Investigator will: 
1. 
Obtain signed informed consent from the potential patient before any study specific 
procedures are performed. 
2. 
Obtain a unique enrolment number, beginning with ‘E#’. The E-code is a 7-digit 
number comprising the centre number, the dosing schedule and the patient number 
within that particular centre.  This number is the patient’s unique identifier and is

Quintiles to support determination of defined PIK3CA mutation status (Part B) or the 
result is ‘unknown’ (Part A or B), mutation status derived from a prior locally-
conducted analysis may be utilised.  This, however, will only be acceptable where the 
analytical methodology/kit has been approved in advance by AstraZeneca. 
Patient stratification by PIK3CA mutation status (Part B) 
Patients will be stratified to PIK3CA mutation positive’ or ‘PIK3CA mutation not detected’ 
arms prior to randomisation.  
Patients assigned a PIK3CA mutation status of ‘Unknown’ will not be eligible to participate in 
Part B. In cases where an archival tumour sample is not received in time to be analysed by the 
central laboratory during screening, defined status may be derived from the blood sample 
alone, or it may be applicable to utilise the status from a prior, locally-conducted tumour 
analysis, see above. 
If a patient is initially stratified to the ‘Not detected’ arm based upon a blood sample alone, or 
blood sample plus locally–conducted tumour analysis, and a subsequent, delayed, tumour 
sample is ‘positive’ – the stratification will not be changed but the discrepancy will be noted.  
Any requirement to assign additional patient places to either stratification arm will be 
determined on an as-needed basis, dependent upon the number of discrepant patients. 
5.2.2 
Procedures for allocation and randomisation 
Part A. Safety Run-In 
A central coordinator at AstraZeneca is responsible for the process of allocation of patients to 
treatment schedules 1 or 2.  

Clinical Study Protocol 
Drug Substance AZD5363  
Study Code D3610C00002 
Edition Number 1 
Date 24 February 2012 
57(131) 
Once the eligibility of a patient for the Safety run-in phase has been confirmed, the study site 
should notify the AstraZeneca coordinator by completion and e-mailing of a registration form.  
Patients will be allocated sequentially, in the order of notification, to each open dosing 
schedule and will be assigned the four digit identification code. 
If either schedule completes, is terminated or recruitment to it is temporarily halted due to e.g., 
a full quota of patients being entered to a cohort; new patients will be allocated to the other, 
ongoing schedule to ensure that eligible consented patients are not denied, or have delayed, 
access to participation in this study. 
If a patient is allocated to the wrong schedule no attempt should be made to remedy the error 
once study material has been dispensed.  The patient will continue with the allocation number 
and study material, and AstraZeneca should be notified as soon as the error is discovered.  
Admission of subsequent patients will continue using the first unallocated number in the 
original numbering sequence. 
In the event of replacement patients being needed to maintain cohort size, that cohort will be 
opened for recruitment and patients will be allocated to it under the system described above 
until the cohort is complete. 
Part B. Randomised Expansion: 
The biostatistics group within AstraZeneca or representative is responsible for generating the 
randomisation scheme. The randomisation scheme will be produced by a computer software 
program that incorporates a standard procedure for generating random numbers. 
Once the eligibility of a patient for the Expansion phase has been confirmed and the patient 
has been stratified based upon PIK3CA mutation status, the study site should contact the 
Centralized IVRS/IWRS by telephone or using the web for allocation of a randomised 
identification code, as described above.  
Patient eligibility must be established before drug is dispensed. 
5.3 
Procedures for handling patients incorrectly enrolled or initiated 
on investigational product 
Patients who fail to meet the inclusion/exclusion criteria should not, under any 
circumstances, be enrolled or receive study medication.  There can be no exceptions to 
this rule. 
Where patients that do not meet the inclusion criteria are enrolled in error or incorrectly 
started on treatment, or where patients subsequently fail to meet the study criteria post-
initiation, the investigator should inform the AstraZeneca Global Study Delivery Team 
Physician immediately. The AstraZeneca Global Study Delivery Team Physician is to ensure 
all such contacts are appropriately documented.

Blinding and procedures for unblinding the study  
This section is applicable to the Part B Randomised Expansion part only. 
5.4.1 
Methods for ensuring blinding 
Study drug will be labelled using a unique Medication Identification (MedID) number, which 
is linked to the randomisation scheme. AZD5363 and matching placebo capsules will be 
identical and presented in the same packaging to ensure blinding of the study drug. 
5.4.2 
Methods for unblinding the study  
Individual treatment codes, indicating the treatment randomisation for each randomised 
patient, will be available to the investigator(s) or pharmacists from the IVRS/IWRS. Routines 
for this will be described in the IVRS/IWRS user manual that will be provided to each centre. 
The treatment code should not be broken except in medical emergencies when the appropriate 
management of the patient requires knowledge of the treatment randomisation. The 
investigator documents and reports the action to AstraZeneca, without revealing the treatment 
given to patient to the AstraZeneca staff. 
AstraZeneca retains the right to break the code for SAEs that are unexpected and are 
suspected to be causally related to an IP 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 patient have been made 
and documented.

available.   
5.5.3 
Doses and treatment regimens 
AZD5363 / matching placebo:  
A twice daily regimen of an oral formulation given on a continuous or intermittent weekly 
dosing schedule.   
Where possible all doses of AZD5363/placebo should be taken, at approximately the same 
times each day, in a fasted state (water to drink only) from at least 2 hours prior to the dose to 
at least 1 hour post-dose. Please also refer to Restrictions (section 5.1) for further guidance 
regarding patient fasting status on study assessment days. 
If vomiting occurs within 30 minutes after AZD5363/placebo dosing, or later if the capsule(s) 
can be identified in the vomit content, the patient can re-take new capsule(s) 
Should a patient miss a scheduled dose, the patient will be allowed to take the dose up to a 
maximum of 2 hours after the scheduled dose time.  If greater than 2 hours after the scheduled 
dose time (other than to allow for receipt of Day 1 paclitaxel under the continuous dosing 
schedule, see Paclitaxel section below), the missed dose should not be taken and the patient 
should take their allotted dose at the next scheduled time.  If a patient needs to take the dose 
earlier for whatever reason, the patient can take the dose up to 2 hours earlier than the 
scheduled dose time.  The patient should make every reasonable effort to take the 
AZD5363/placebo capsule(s) on time.  
Paclitaxel:  
A weekly single intravenous (iv) infusion of 90 mg/m2 given over approximately one hour 
(with the actual time recorded in the CRF) via a rate-controlling device.  Patients will receive 
3 consecutive weekly paclitaxel infusions (given on Day 1 of weeks 1, 2 and 3), followed by 
one week off-treatment within each 28-day treatment cycle (see below). Please also refer to 
local paclitaxel label.  
Treatment Schedules: 
Under both the continuous and intermittent dosing schedules, first receipt of paclitaxel will be 
on Cycle 1, Day 1; first receipt of AZD5363/placebo will be on Day 2.  
Thereafter, under the intermittent dosing schedule, weekly AZD5363 regimens will continue 
to start on the day after receipt of paclitaxel.

Note:  
For the continuous dosing schedule; on those days in which both paclitaxel and 
AZD5363/placebo are to be received – the paclitaxel infusion must be completed 
before the first dose of AZD5363/placebo is given. 
For the intermittent dosing schedule; AZD5363/placebo should not be taken on any 
week that the paclitaxel infusion is not administered – either due to a scheduled off-
drug week or unscheduled omission or delay.  Where paclitaxel is ceased entirely, 
AZD5363/placebo may be continued on a weekly schedule at the investigator’s 
discretion.  
For the purposes of planning - a standard treatment cycle is defined as 4 weeks:- comprising 
three weeks of paclitaxel followed by one week off-therapy, regardless of receipt of 
AZD5363/placebo.  Where possible, investigators are strongly urged to maintain patients to 
this schedule.  For Part A dose cohort evaluability it is necessary for Cycle 1 to comprise three 
doses of paclitaxel within a four week period in the absence of a DLT (see Section 5.10.5).  
For study conduct - the start of a cycle will be determined by commencement of paclitaxel 
following a period off-therapy of t1 week.  After Cycle 1, a treatment cycle will be defined as 
receipt of a minimum of one, and a maximum of three, weeks of paclitaxel therapy followed 
by a period of  t1 week off-therapy, regardless of receipt of AZD5363/placebo.    
For example; if a patient completes a standard 4 week cycle (Cycle A), but then 
receipt of paclitaxel is delayed by a further week, the next cycle will not formally 
commence until next first receipt of paclitaxel (Day 1 Cycle B).  Under the 
continuous dosing schedule - during the ‘missed’ week, the patient will continue to 
receive AZD5363/placebo; this period will be taken as an extension to the previous 
cycle (Cycle A). 
Where paclitaxel has ceased, but patients continue to receive AZD5363/placebo:  The start of 
a cycle will be the day of first receipt of AZD5363/placebo (or the day before that if the 
patient is on the intermittent dosing schedule).  Each cycle will be 28 days.

If receipt of AZD5363/placebo is suspended for >28 continuous days, this study therapy 
should be permanently withdrawn.  Any request to continue therapy after such a suspension 
must be agreed with the AstraZeneca Study Delivery Team Physician.   
During the Part A dose evaluation period (Cycle 1).  If a patient experiences a DLT or an 
unacceptable toxicity occurs, AZD5363 treatment will be stopped and supportive therapy 
administered as required.  If the toxicity resolves, or reverts to CTCAE grade 0 or 1 or 
baseline (pre-study), levels within 28 days of onset, and the patient is showing clinical benefit, 
treatment with AZD5363 may be restarted at a lower dose level at the discretion of the 
investigator.  Dose reductions should be in single or multiple increments of 80 mg bd to a 
minimum dose of 80 mg bd for the continuous dosing schedule and 120 mg bd for the 
intermittent dosing schedule. 
During the Part A post-dose evaluation period (Cycle 2 onwards) and Part B.  Any 
toxicity observed during the course of the study that is suspected of being related to 
AZD5363/matching placebo may be managed at the discretion of the investigator by dose 
interruption or by dose reduction. Repeat dose interruptions are to be allowed as required, for 
a maximum of 4 weeks (28 days) on each occasion.  Dose reductions should be in single or 
multiple increments of 80 mg bd to to a minimum dose of 80 mg bd for the continuous dosing 
schedule and 120 mg bd for the intermittent dosing schedule. 
All dose modifications and interruptions (including any missed doses due to AEs), and the 
reasons for the dose modifications/interruptions are to be recorded in the CRF. 
See Appendix H for instruction regarding AZD5363/placebo dose modifications 
Paclitaxel 
During the Part A dose evaluation period (Cycle 1).  Paclitaxel first dose, Cycle 1, Day 1, 
must be administered at 90 mg/m2.  Dose reductions or dose interruptions/omissions for the 
second and third infusions in Cycle 1 may be implemented at the discretion of the investigator 
to alleviate suspected toxicities. Single reductions should be in steps of no more than 20 
mg/m2.  Patients receiving less than 80% of the intended dose (90 mg/m2 x 3) within the 28 
days, and that do not experience a DLT, will not be evaluable under the dose escalation 
review criteria (see section 5.10.5)  
Cycle 1 will comprise a 28-day evaluation period, regardless dose reductions or dose 
omissions, unless the patient experiences a DLT. 
During the Part A post-dose evaluation period (Cycle 2 onwards) and Part B.  At the 
discretion of the investigator, reduced doses may be administered in subsequent cycles to 
alleviate suspected toxicities according to local clinical practice.  In the event of suspected 
neutropenia, guidance regarding paclitaxel dose modifications is provided in Appendix H. 
If receipt of paclitaxel is suspended for 28 continuous days, this study therapy should be 
permanently withdrawn.  Any request to continue therapy after such a suspension must be 
agreed with the AstraZeneca Study Delivery Team Physician.

Safety Run-In: Starting dose and dose escalation scheme 
For Study Part A; administration of AZD5363 will commence, when combined with 
paclitaxel, at cohort 1 of each schedule at doses of: 
x
Continuous dosing: 320 mg bd (640 mg daily). 
x
Intermittent dosing (4 days of treatment followed by 3 days off-treatment: 360 mg 
bd (720 mg daily). 
These starting doses are below the AZD5363 monotherapy doses of: 400 mg bd (continuous 
dosing schedule) and 480 mg bd (intermittent dosing schedule) deemed tolerable in the 
ongoing Phase I multiple-ascending dose study (D3610C00001) in patients with advanced 
solid malignancies at the time of initiating Part A.   
Patients will be enrolled to ensure a minimum of three and a maximum of six evaluable 
patients per dose escalation cohort.  For procedures and definitions associated with dose 
escalation, see Section 5.10. 
5.5.6

All study drugs should be kept in a secure place under appropriate storage conditions.  The IP 
label on the bottle specifies the appropriate storage. 
5.6 
Concomitant and post-study treatment(s) 
Information on any treatment received by the patient, with reasons for its provision, will be 
recorded in the eCRF from 4 weeks prior to starting study treatment up to 28 days after the 
last dose of AZD5363/placebo or until objective progression, whichever is the latest.  If 
medically feasible, patients taking regular medication - with the exception of potent inhibitors 
or inducers or substrates of CYP3A4 or substrates of CYP2D6 - (see Section 4.2 Exclusion 8 
and Appendix G), should be maintained on it throughout the study period. 
Other anticancer agents, investigational agents and radiotherapy should not be given while the 
patient is on study treatment although radiation for palliation at focal sites is permitted. 
Pre-medication will be allowed after, but not before the first dose of study treatment.  This 
includes management of diarrhoea, nausea and vomiting. Pre-medication required for 
paclitaxel therapy is allowed as per local standards and label.  
Blood transfusions are allowed at any time during the study. 
Patients already receiving erythropoietin at the time of screening for the study may continue it 
providing they have been receiving it for more than one month at the time study treatment is 
started.  Prophylactic erythropoietin should not be started during Cycle 1 of the study but may 
be started during or after Cycle 2.  
Granulocyte colony stimulating factors should not be used prophylactically during Cycle 1.  
Use of prophylactic colony stimulating factors may be considered after Cycle 1 following 
discussion with the AstraZeneca Study Delivery Team Physician. 
Patients may receive bisphosphonates for the treatment of bone metastases. 
Patients may take warfarin or a coumarin preparation but it is recommended that they should 
have their anticoagulation monitored carefully and dose adjusted accordingly. 
Patients may take corticosteroids, however, increased vigilance is recommended on electrolyte 
and/or glucose levels due to the potential for corticosteroid-related metabolic disturbance. 
Supportive care and other medications that are considered necessary for the patient’s well-
being, may be given at the discretion of the investigator. 
Other medication, which is considered necessary for the patient’s safety and well being, may 
be given at the discretion of the investigator and recorded in the appropriate sections of the 
eCRF.

to whom the AZD5363/matching placebo was dispensed, the quantity and date of dispensing 
and unused AZD5363/matching placebo returned to the investigator.  This record is in 
addition to any drug accountability information recorded on the CRF.  Any discrepancies must 
be accounted for on the appropriate forms.  Certificates of delivery and return must be signed, 
preferably by the investigator or a pharmacist, and copies retained in the investigator site file. 
All unused or returned medication, after drug accountability, should be destroyed according to 
local AZ procedures, this can be at site or in the marketing company wherever possible.  In the 
event that this is not possible, the medication should be returned to the local distribution 
centre for destruction. 
AZD5363/matching placebo and label accountability records will be maintained by the study 
site personnel.  These will be used in conjunction with the handling and preparation 
worksheets for recording all drug and label use.

Discontinuation of investigational product 
Patients may be discontinued from IP at any time, without prejudice to further treatment. If a 
patient discontinues IP for reasons other than death, then they should still continue in the 
study up to objective disease progression assessed by RECIST 1.1, unless they withdraw 
consent from the study. 
Patients may be discontinued from IP in the following situations: 
x
Patient decision.  The patient is at any time free to discontinue treatment, without 
prejudice to further treatment. 
x
Adverse Event. 
x
Severe non-compliance to study protocol in the judgement of the investigator and/or

5.8.1 
Procedures for discontinuation of a patient from investigational product  
A patient that decides to discontinue IP will always be asked about the reason(s) and the 
presence of any adverse events.  If possible, they will be seen and assessed by an 
investigator(s) (See Figure 5 and Figure 6 for assessments to be performed).  Adverse events 
will be followed up (See Sections 6.4.3 and 6.4.4); diary cards, questionnaires and all study 
drugs should be returned by the patient. 
If a patient is withdrawn from study, see Section 5.9. 
It is important to determine the wishes of the patient – to differentiate between discontinuation 
from IP or complete withdrawal from the study when consent is withdrawn. 
5.9 
Withdrawal from study 
Patients are at any time free to withdraw from study (IP and assessments), without prejudice 
to further treatment (withdrawal of consent).  Such patients will always be asked about the 
reason(s) and the presence of any adverse events.  If possible, they will be seen and assessed 
by an investigator.  Adverse events will be followed up (See Sections 6.4.3 and 6.4.4); diary 
cards, questionnaires and all study drugs should be returned by the patient. 
Part A.  Safety Run-in: Patients that are withdrawn from the study but are evaluable per the 
definition in Section 5.10.5 will not be replaced.  Any patient that is withdrawn and is not 
evaluable will be replaced to ensure a minimum number of evaluable patients. 
Part B. Randomised Expansion:  Patients that are withdrawn will not be replaced  
At the point of withdrawal, no further study procedures or follow up assessments will be 
performed and no further data will be collected. A call should be made to the IVRS system to 
discontinue the patient. 
The reason for withdrawal from the study should be recorded on the eCRF. Patients will be 
considered to have withdrawn from the study only due to one of the following reasons: 
x
Patient decision (patients withdraws consent from participating in the study).

concerning participation in other aspects of the main study.  Procedures for withdrawal of 
consent for donated biological samples are outlined in Section 7.5. 
5.9.1 
Screening failures 
Screening failures are patients who do not fulfil the eligibility criteria for the study and are 
therefore not enrolled. These patients should have their reason for study withdrawal recorded 
as ‘Eligibility Criteria not fulfilled’ (ie, patient does not meet the required inclusion/exclusion 
criteria). This reason for study withdrawal is only valid for screening failures (not enrolled 
patients).

Safety Review Committee and Dose Escalation Process  
After each dose level during Part A of the study, the SRC will evaluate the safety and 
tolerability and pharmacokinetics of AZD5363 to decide the next dose. 
The SRC will consist of: 
x
Study Delivery Team Physician, who will chair the committee, or delegate. 
x
Principal Investigator or delegate from each investigational site. 
In addition, other physicians from the following may be invited: 
x
Patient Safety Physician or delegate. 
x
Medical Science Director or delegate.

Senior physician from another project. 
The Study Pharmacokineticist, Study Statistician, Patient Safety Scientist, and Study Delivery 
Team Leader may also be invited as appropriate.  The SRC Remit document for this study will 
define the exact membership and who should be present for decisions to be made. 
Further internal or external experts may be consulted by the SRC as necessary.  The Patient  
Safety Physician or delegate should always be present at the SRC if there are safety issues for 
discussion. 
Once there are at least 3 evaluable patients at a dose level the SRC will review and assess all 
available safety data from the cohort, together with available PK and pharmacodynamic data 
to make a decision on the dose for the next cohort of patients.  Any dose interruptions and 
reductions will be taken into account.   
The decision may be to: 
1. 
Proceed with dose escalation – refer to Section 5.10.3. 
2. 
Expand the cohort to a maximum of 6 evaluable patients. 
3. 
Reduce the dose either to a previous lower dose level (up to a maximum of 6 
evaluable patients) or to an intermediate lower dose level. 
4. 
Revise the dosing schedule for the subsequent cohort (intermittent scheduling arm 
only).  
5. 
Define the RD (and NTD/MTD where applicable).  To define a RD or the MTD, 6 
evaluable patients must be assessed at that dose level.  The SRC may elect to assess 
up to a further 6 evaluable patients at the identified MTD to confirm the dose 
selection.  To determine the NTD 2 patients, of up to 6 patients, must experience 
DLTs at that dose level. 
6. 
Stop the dose escalation part of the study. 
When there are other patients that are ongoing at the time of this review, the SRC may decide 
to defer their decision until these further patients become evaluable. 
Any patient started on treatment in error, as he/she failed to comply with all of the selection 
criteria but meets the criteria of an evaluable patient, will be reviewed on a case by case basis 
by the SRC to determine if the patient should be included or excluded in the decision for dose 
escalation. 
The decisions and decision-making of the SRC on the next dose level will be documented and 
provided to the investigators prior to dosing any new patients.

Dose Escalation: Parameters. 
Dose escalation and reduction per cohort will be determined by the SRC with reference to the 
following logic: 
x
If no DLT is observed (for definition see Section 5.10.6) in a cohort of 3-6 
evaluable patients then dose escalation may occur.  Dose increases will be permitted 
after review of data from a minimum of 3 evaluable patients has been performed.   
x
If one patient experiences a DLT in a group of 3 or more evaluable patients then the 
cohort will be expanded to include 6 evaluable patients.  If only one DLT is 
observed in the complete cohort of 6 evaluable patients then dose escalation may 
occur. 
x
If 2 or more patients experience a DLT in a group of up to 6 evaluable patients, 
irrespective of the number of patients enrolled, the dose will be considered not 
tolerated and recruitment to the cohort and dose escalation will cease.  A lower 
intermediary dose (reduction) may be considered in order to better define the MTD. 
The dose may initially be increased up to a level the SRC declare is safe and appropriate based 
on clinical PK and/or safety data. The SRC will determine the dose escalation/reduction based 
on the above criteria at the end of each dose group. 
Based on emerging data, including available PK and/or safety data and/or pre-clinical data, the 
SRC can consider alternative treatment schedules, including once-daily dosing of AZD5363, 
in consultation with AZ.  
When an NTD is defined, dose escalation/ will be stopped. All patients receiving the NTD 
should have their dose reduced to a tolerated dose or discontinue AZD5363 if a tolerated dose 
has not been defined. An interim dose (ie, one between the NTD and the last dose tested 
before NTD) may be assessed to determine the MTD and the SRC will decide this upon 
review of the data. The MTD will be defined as the last dose assessed below the NTD. 
If dose reductions or delays greater than those allowed under this protocol (see section 5.5.4) 
occur during the DLT evaluation period, the patient will be considered either as not evaluable 
or as having attained a DLT (see Section 5.10.6 for definition of DLT).  
The DLT evaluation period ends following the completion of all assessments on the last day 
of the first cycle (Day 28). 
Escalations will not exceed doubling of the dose of the prior cohort.  
Intra-patient dose escalation is not permitted.

5.10.4 
Definition of maximum tolerated dose 
A primary objective of the Part A Safety Run-in phase is to determine a RD to take forward to 
the Expansion phase. It may not be necessary to escalate to NTD/MTD to establish the RD. 
Where it is necessary, or where the SRC deems it appropriate to do so, the following criteria 
will apply for determination of NTD/MTD.  
A dose will be considered non-tolerated, and dose escalation will cease, if 2 or more of up to 6 
evaluable patients experience a DLT at that dose level. Once the NTD is defined the MTD 
will be confirmed at the previous dose-level below the NTD or a dose between the NTD and 
the last tolerated dose may be investigated. Six evaluable patients are required to determine 
the MTD. 
5.10.5 
Definition of evaluable patient for Part A 
An evaluable patient is defined as one that, during Cycle 1: Weeks 1 to 4 has:  
x
Completed the minimum safety evaluation requirements and has received: 

At least 80% of the total intended dose of AZD5363 within the 28 day cycle. 

3 doses of paclitaxel, comprising at least 80% of the total specified dose (where 
total dose is 3 x 90 mg/m2 = 270 mg/m2)*, within the 28 day cycle**.    
or  
has experienced a DLT prior to fulfilling the above criteria. 
Note: 
* Cycle 1, Day 1, paclitaxel first dose must be administered at a dose of 90 mg/m2.  
Dose reductions for the second and third infusions in Cycle 1 may be implemented, 
if required under the investigator’s discretion for suspected toxicities. Single 
reductions can be in increments of no more than 20 mg/m2 to a minimum dose of of 
60 mg/m2.   
** A dose delay to the second and/or third paclitaxel infusion during Cycle 1 is 
permissable, providing that the total delay is no more than 7 days.  All three doses 
must be received within the 28 day cycle. 
5.10.6 
Definition of dose-limiting toxicity  
A DLT is defined as: 
x
An AE or laboratory abnormality considered to be related to paclitaxel, that 
commences at any time during the DLT evaluation period (Cycle 1) and meets 
either of the following criteria:

1. 
Requires a dose reduction or omission to <60% of the intended Cycle 1 
total paclitaxel dose (90 mg/m2 x 3). 
2. 
Any delay to the administration of weekly paclitaxel chemotherapy on 
D1 of Cycle 2 by 7 days as a consequence of paclitaxel induced toxicity 
x
An AE or laboratory abnormality considered to be related to AZD5363, that 
commences at any time during the DLT evaluation period (Cycle 1) and meets any 
of the following criteria: 
1. 
Haematological toxicity: 

CTCAE grade 4 haematological toxicity of any duration. 

Febrile neutropenia (CTCAE grade 3 with temperature 38.5°C which is 
unresponsive to antipyretics). 

CTCAE grade 3 neutropenia requiring hospitalisation. 

CTCAE grade 3 thrombocytopenia associated with non-traumatic bleeding 
(but not applicable to patients on therapeutic anticoagulation). 
2. 
Clinical chemistry toxicity: 

CTCAE  Grade 3 hyperglycaemia (glucose >13.9 mmol/L) for more than 1 
week, despite optimal intervention which is not attributable to another co-
morbidity. 

Grade 4 hyperglycaemia (glucose >27.8 mmol/L). 

AST or ALT >10x ULN and AZD5363 is considered the most likely cause. 

AST or ALT >8x ULN, when combined with doubling of bilirubin from 
baseline, and AZD5363 is considered the most likely cause. 
3. 
Cardiovascular toxicity: 

QTc (Fridericia’s or Bazett’s correction) interval >500msec or QTc increase 
>60msec from baseline on two ECGs at least 30 minutes apart, that cannot be 
attributed to another cause. 

Symptomatic congestive cardiac failure (NYHA class III/IV) and a drop in 
LVEF which cannot be attributed to another cause.  Note: Concomitant use of 
vasotonic drugs, adrenergic blockers, negative inotropic agents and anti-


A decrease in LVEF of 20% to a level below the institution’s lower limit of 
normal range. 

CTCAE grade 3 hypotension which cannot be attributed to another cause. 
4. 
Other toxicities:

Clinically significant rash that despite optimal treatment remains CTCAE grade 
3 for 5 days or longer and that cannot be attributed to another cause.  

CTCAE grade 3 nausea, vomiting or diarrhoea, despite optimal anti-emetic or 
anti-diarrhoeal therapy, and which cannot be attributed to another cause. 

Any other CTCAE grade 3 toxicity which, in the opinion of the investigator, 
is clinically significant and related to AZD5363. 

Any delay to the administration of weekly paclitaxel chemotherapy on Day 1 of 
Cycle 2 by 7 days as a consequence of AZD5363 induced toxicity. 

Any other toxicity that is greater than that at baseline, is clinically significant 
and/or unacceptable, does not respond to supportive care and results in a 
disruption of dosing schedule of more than 14 days. 
Any event, including significant dose reductions or omissions, judged to be a DLT by the 
SRC. 
A DLT excludes:  
1. 
Alopecia of any grade. 
2. 
Isolated laboratory changes of any grade without clinical sequelae or clinical 
significance. 
The National Cancer Institute (NCI) CTCAE version 4.1 will be used whenever applicable to 
characterise DLTs.  However, pre defined stopping criteria will supersede the CTCAE criteria. 
Where a criterion for a DLT is reached, any subsequent delays in dosing or dose reductions of 
paclitaxel or AZD5363 due to toxicity are considered to occur after the DLT evaluation 
period. 
If patients present with a potential DLT, the patient should be promptly investigated to define 
the aetiology of the symptoms.  The use of appropriate (ie, non-restricted) medications in 
prophylactic or therapeutic management of toxicities are permitted.   
The decision to interrupt dosing or to stop a patient from receiving further dosing will be 
taken by the principal or co-investigator, in consultation with the AZ Study Delivery Team

Physician, based on the clinical significance of the observed toxicity.  If the toxicity is 
subsequently determined by the SRC to not be a DLT, this patient will be replaced. 
The principal investigator, in consultation with the AZ Study Delivery Team Physician, may 
request replacement of patients who develop DLTs that are attributed to confounding factors 
and concomitant medications started during the DLT assessment period.  Confounding 
medications for the specific DLT may be prohibited for the new patient(s) recruited to that 
dose group 
6. 
COLLECTION OF STUDY VARIABLES 
6.1 
Recording of data 
The Rave Web Based Data Capture (WBDC) system will be used for data collection and 
query handling.  The investigator will ensure that data are recorded on the eCRFs as specified 
in the study protocol and in accordance with the instructions provided. 
The investigator ensures the accuracy, completeness and timeliness of the data recorded and 
of the provision of answers to data queries according to the Clinical Study Agreement (CSA). 
The investigator will sign the completed eCRFs.  A copy of the completed eCRFs will be 
archived at the study site. 
6.2 
Data collection at enrolment and follow-up 
6.2.1 
Enrolment procedures 
Written informed consent must be obtained prior to conduct of any study specific assessments. 
Procedures that are part of standard care may occur before informed consent is obtained. 
A list of procedures and assessments described in the Study Plans (Figure 5: Continuous 
dosing; Figure 6: Intermittent dosing) for the screening visit must be completed within 4 
weeks (-28 days) of enrolment. At screening, consenting patients will be assessed to ensure 
that they meet inclusion and exclusion criteria (Sections 4.1 and 4.2). 
Demographic data and other characteristics will be recorded at screening and will include: 
date of birth, gender, race, menstrual status and smoking history. 
Part B. Randomised Expansion: Each patient’s PIK3CA mutation status must be determined at 
screening from a blood and archival tumour sample to enable the patient to be stratified as 
PIK3CA mutation positive or not detected prior to randomisation (see section 5.2.1): 
x
Patients will be stratified to the PIK3CA mutation positive arm where either one of 
the sample-type analyses is positive.  Patients will be stratified to the not-detected 
arm where both sample type analyses are negative. 
x
It is requested that all efforts are made to ensure that archival tumour tissue is 
provided for this stratification analysis.  Where tissue cannot be made available in a 

Clinical Study Protocol 
Drug Substance AZD5363  
Study Code D3610C00002 
Edition Number 1

76(131) 
timely manner, PIK3CA mutation stratification may be conducted on the blood 
sample analysis alone.  In this event, tumour tissue must be provided for 
retrospective PIK3CA mutation analysis prior to completion of treatment Cycle 1.   
x
Where a patient has been assigned to the not-detected arm from blood sample 
analysis alone but the retrospective tumour tissue analysis is PIK3CA mutation 
positive - the patient will remain stratified to the not-detected arm.  The discrepancy 
will be noted and an additional patient allocation may be made for this arm.   
x
In the event that one stratification arm (PIK3CA mutation positive or not-detected) 
completes recruitment before the other, new candidate patients will be requested to 
provide separate, initial, informed consent to obtain a blood and/or tumour tissue 
sample to screen for PIK3CA mutation status.  Patients with status appropriate for 
entry to the open stratification arm will be invited to provide informed consent for 
entry to the study. 
6.2.2 
PIK3CA Mutation Status 
Patient response to treatment will be assessed against the tumour PIK3CA mutation status to 
determine whether the mutation confers any increased tumour sensitivity to AZD5363. 
Blood and most recent archival tumour samples will be collected at screening (see Figure 5 
and Figure 6) with reference to the criteria and restrictions detailed in section 5.2.1.  The 
PIK3CA mutation assay(s) will genotype for a set of mutations that will cover the majority of, 
but not all, mutations in the PIK3CA gene that have been thus far identified in breast cancer 
patients.  Therefore, there may be patients carrying either a rare mutation, not included in the 
assay(s) used, or who have a level of mutation in cfDNA or tumour tissue DNA beyond the 
range of sensitivity of the selected assay(s).  In this case, their mutation will not be identified 
under the protocolled testing.  In acknowledgment of this, patients who are shown not to be 
‘mutation positive’ in either cfDNA or tumour tissue DNA will be categorised as ‘mutation 
not detected’, rather than a more definitive ‘mutation negative’. 
During Study Part B, PIK3CA mutation status will be utilised to stratify patients to ‘positive’ 
and ‘not detected’ arms (see section 5.2.1). 
6.2.3 
Follow-up procedures 
Patients will be followed up as detailed below unless prior withdrawal from the study or 
death: 
Part A. Safety Run-in:  Patients will be followed to discontinuation of study drug / completion 
of the 28-day safety follow-up.  
Part B. Randomised Expansion:  Patients will be followed to objective disease progression.

Date 24 February 2012 
77(131) 
6.2.3.1 
Study Drug Discontinuation 
The discontinuation visits for AZD5363/matching placebo and paclitaxel should take place at 
the time of the last dose of the applicable study drug, or as soon as possible following 
confirmation that no further dosing will take place. 
6.2.3.2 
28-Day Safety follow-up     
For safety follow-up as a minimum, telephone contact should be made with the patient 
28 days following the discontinuation of both AZD5363/matching placebo and paclitaxel, to 
follow up on any SAE/AE’s, surgery, concomitant medications, concomitant procedures, 
radiotherapy and subsequent cancer therapy.  Any SAEs will be followed to resolution where 
possible.   
6.2.3.3 
 Progression follow-up 
Part B. Randomised Expansion only.  Patients who discontinue AZD5363/matching placebo 
for reasons other than progression will continue RECIST 1.1 assessments every 12 weeks 
(from Cycle 1 Day 1) r7days up to objective disease progression.  This schedule of RECIST 
1.1 assessments should be maintained even if study treatment cycles have been delayed.  Only 
new SAEs due to study procedures should be collected.     
6.3 
Efficacy  
6.3.1 
Tumour assessments 
RECIST 1.1 criteria will be used to assess patient response to treatment by determining 
change in tumour size at 12 weeks, percentage of patients without progressive disease, at 12 
weeks, overall response rate (ORR), BoR, DoR and PFS. The RECIST 1.1 guidelines for 
measurable, non-measurable, target, and non-target lesions (NTL) and the objective tumour 
response criteria (CR, PR, stable disease [SD], or progressive disease [PD]) are presented in 
Appendix F. 
RECIST assessments will be performed using CT or MRI scans of the chest, abdomen and 
pelvis.  Baseline assessments should encompass all areas of known predilection for metastases 
in the disease under evaluation and should additionally investigate areas that may be involved 
based on signs and symptoms of individual patients.  Baseline assessments should be 
performed no more than 28 days before the start of study treatment, and ideally should be 
performed as close as possible to the start of study treatment.   
The methods of assessment of tumour burden used at baseline (CT or MRI scans of the chest, 
abdomen and pelvis) must be used at each subsequent follow-up assessment.  
Follow-up assessments will be performed every 12 weeks (r7 days) after start of treatment 
(Cycle 1 day 1) until objective disease progression as defined by RECIST 1.1.  For the Safety 
Run-in phase (Part A), tumour assessments will stop after cessation of study drug where prior 
to progression.  For the Randomised Expansion phase (Part B), if a patient discontinues 
treatment (and/or receives a subsequent cancer therapy) prior to progression then the patient 

Clinical Study Protocol 
Drug Substance AZD5363  
Study Code D3610C00002 
Edition Number 1

78(131) 
should still continue to be followed until objective disease progression as defined by RECIST 
1.1. 
Any other sites at which new disease is suspected should also be appropriately imaged.  If an 
unscheduled assessment was performed and the patient has not progressed, every attempt 
should be made to perform the subsequent assessments at their scheduled visits. 
For Part A, for patients with non-measurable disease only at baseline, categorisation of 
objective tumour response assessment will be based on the RECIST 1.1 criteria of response: 
complete response (CR), PD (progression of disease) and Non CR/Non PD. 
For Part B, categorisation of objective tumour response assessment will be based on the 
RECIST 1.1 criteria of response: CR, PR (partial response), SD (stable disease) and PD 
(progression of disease).  Target lesion (TL) progression will be calculated in comparison to 
when the tumour burden was at a minimum (i.e. smallest sum of diameters previously 
recorded on study).  In the absence of objective progression, tumour response (CR, PR, SD) 
will be calculated in comparison to the baseline tumour measurements obtained before starting 
treatment. 
If the Investigator is in doubt as to whether objective progression has occurred, particularly 
with response to NTL or the appearance of a new lesion, it is advisable to continue treatment 
until the next scheduled assessment, or sooner if clinically indicated, and reassess the patient’s 
status.  If repeat scans confirm progression, then the date of the initial scan should be declared 
as the date of objective progression. 
To achieve ‘unequivocal progression’ on the basis of non-target disease, there must be an 
overall level of substantial worsening in non-target disease such that, even in presence of SD 
or PR in target disease, the overall tumour burden has increased sufficiently to merit 
discontinuation of therapy.  A modest ‘increase’ in the size of one or more NTLs is usually 
not sufficient to quality for unequivocal progression status. 
It is important to follow the assessment schedule as closely as possible.  Please refer to the 
study plan in Figure 5 and Figure 6. 
The primary analysis for this study will be based on the tumour assessments recorded on the 
eCRF. 
Radiological examinations performed in the conduct of this study for RECIST response 
assessments must be retained at site as source data and a copy anonymised for personal 
identifiers, e.g. name, initials, be available for collection by the Sponsor to support any future 
regulatory requests.

6.4.1 
Definition of adverse events  
An adverse event 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 (eg, nausea, chest pain), signs (eg, tachycardia, enlarged liver) or the 
abnormal results of an investigation (eg, laboratory findings, ECG). In clinical studies, an AE 
can include an undesirable medical condition occurring at any time, including run-in or 
washout periods, even if no study treatment has been administered. AEs will be graded 
according to CTCAE version 4.1. 
The term AE is used to include both serious and non-serious AEs. 
6.4.2 
Definitions of serious adverse event 
A serious adverse event (SAE) is an AE occurring during any study phase (ie, run-in, 
treatment, washout, follow-up), that fulfils one or more of the following criteria: 
x
Results in death. 
x
Is immediately life-threatening. 
x
Requires in-patient hospitalisation or prolongation of existing hospitalisation . 
x
Results in persistent or significant disability/incapacity or substantial disruption of 
the ability to conduct normal life functions. 
x
Is a congenital abnormality or birth defect. 
x
Is an important medical event that may jeopardise the patient 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. 
6.4.3 
Recording of adverse events 
Time period for collection of adverse events  
Adverse Events will be collected from time of signature of informed consent, throughout the 
treatment period up to, and including, the follow-up period. The follow-up period is defined as 
28 days after study treatment (both AZD5363/placebo and paclitaxel) is discontinued. 
For the Randomised Expansion phase, SAEs occurring after the 28-day follow-up, that are 
considered related to study procedures, should continue to be recorded while patients are 
followed-up for disease progression.

If the investigator learns of any SAE(s), including death, at any time after a patient has 
completed the study, and he/she considers there is a reasonable possibility that the event is 
related to AZD5363, the investigator should notify AstraZeneca. 
Follow-up of unresolved adverse events 
Any AEs that are unresolved at the patient’s last visit in the study will be followed up by the 
investigator for as long as medically indicated, but without further recording in the CRF. 
AstraZeneca retains the right to request additional information for any patient with ongoing 
AE(s)/SAE(s) at the end of the study, if judged necessary. 
Variables 
The following variables will be collect for each AE; 
x
AE (verbatim). 
x
The date when the AE started and stopped. 
x
Whether the AE is serious or not. 
x
Investigator causality rating against the IP (yes or no). 
x
Investigator causality rating against paclitaxel (yes or no).  
x
Action taken with regard to IP. 
x
Action taken with regard to paclitaxel. 
x
Outcome. 
In addition, the following variables will be collected for SAEs: 
x

Description of AE. 
The grading scales found in the revised National Cancer Institute CTCAE version 4.1 will be 
utilised for all events with an assigned CTCAE grading.  For those events without assigned 
CTCAE grades, the recommendation in the CTCAE criteria that converts mild, moderate and 
severe events into CTCAE grades should be used.  A copy of the CTCAE version 4.1 can be 
downloaded from the Cancer Therapy Evaluation Program website (http://ctep.cancer.gov). 
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 6.4.2.  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. 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. 
Causality collection 
The Investigator will assess causal relationship between IP and each Adverse Event, 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?’ 
For SAEs causal relationship will also be assessed for other medication, including paclitaxel 
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. 
Adverse Events based on signs and symptoms 
All AEs spontaneously reported by the patient or reported in response to the open question 
from the study personnel: ‘Have you had any health problems since the previous visit/you 
were last asked?’, or revealed by observation will be collected and recorded in the CRF. When 
collecting AEs, the recording of diagnoses is 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. 
Adverse Events based on examinations and tests 
The results from protocol mandated laboratory tests and vital signs will be summarised in the 
Clinical Study Report (CSR).  Deterioration as compared to baseline in protocol-mandated 

Clinical Study Protocol 
Drug Substance AZD5363  
Study Code D3610C00002 
Edition Number 1 
Date 24 February 2012 
82(131) 
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 IP. 
If deterioration in a laboratory value/vital sign is associated with clinical signs and symptoms, 
the sign or symptom will be reported as an AE and the associated laboratory result/vital sign 
will be considered as additional information.  Wherever possible the reporting investigator 
uses the clinical, rather than the laboratory term (eg, anaemia versus low haemoglobin value). 
In the absence of clinical signs or symptoms, clinically relevant deteriorations in non-
mandated parameters should be reported as AE(s). 
Deterioration of a laboratory value, which is unequivocally due to disease progression, should 
not be reported as an AE/SAE. 
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. 
Hy’s Law 
Cases where a patient shows an AST or ALT 3x ULN or total bilirubin  2x ULN may need 
to be reported as SAEs, please refer to Appendix E ‘Actions required in cases of combined 
increase of Aminotransferase and Total Bilirubin – Hy’s Law’, for further instructions. 
Disease progression 
Disease progression can be considered as a worsening of a patient’s condition attributable to 
the disease for which the IP is being studied.  It may be an increase in the severity of the 
disease under study and/or increases in the symptoms of the disease.  The development of 
new, or progression of existing metastasis to the primary cancer under study should be 
considered as disease progression and not an AE.  Events, which are unequivocally due to 
disease progression, should not be reported as an AE during the study. 
Deaths 
All deaths (both cancer-related and other) that occur during the study and within 28 days after 
the last dose of AZD5363 must be reported as follows: 
x
Death clearly resulting from unequivocal disease progression should be reported to the 
study monitor at the next monitoring visit and should be documented on the relevant 
eCRF but should not be reported as an AE or SAE. 
x
When death is not due to progression of disease under study, the AE causing death 
must be reported to the study monitor as a SAE within 24 hours. The report should 
contain a comment regarding the co-involvement of progression of disease, if 
appropriate, and should assign main and contributory causes of death. 
In the event of death, the patient will be considered as having completed the study.

New cancers 
The development of a new cancer should be regarded as an AE and will generally meet at 
least one of the serious criteria. New cancers are those that are not the primary reason for 
administration of study treatment and have been identified after inclusion of the patient into 
the clinical study. They do not include metastases of the original cancer. Symptoms of 
metastasis or the metastasis itself should not be reported as an AE/SAE as they are considered

Reporting of serious adverse events (SAEs) 
All SAEs have to be reported, whether or not considered causally related to the IP, or to the 
study procedure(s). All SAEs will be recorded in the CRF. 
If any SAE occurs in the course of the study, then investigators or other site personnel inform 
appropriate AstraZeneca representatives within one day ie, immediately but no later than the 
end of the next business day 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. 
For fatal or life-threatening adverse events 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 
within one calendar day ie, immediately but no later than the end of the next business day 
of when he or she becomes aware of it. 
Once the Investigators 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. 
The reference document for definition of expectedness/listedness is Section 5.4 of the 
Investigators’ Brochure for AZD5363, and the EU Summary of Product Characteristics (SPC) 
for paclitaxel.

Patient reported outcomes (PRO) 
6.5.1 
Quality of Life: EORTC QLQ C-30 and BR-23 questionnaires (Part B: 
Randomised expansion only). 
These questionnaires were developed to assess and monitor changes from baseline in global 
health status / quality of life and disease-related symptoms. Validated translations of the 
questionnaires will be administered as appropriate.   
The European Organisation for the Research and Treatment of Cancer Quality of Life 
Questionnaire, EORTC QLQ-C30, is a 30-item generic instrument designed specifically to 
assess quality of life (QoL) in patients with cancer, and is applicable across a range of cancer 
types, treatments, and cultural settings. The instrument incorporates 5 functional scales 
(physical, role, cognitive, emotional, and social), 3 symptom scales (fatigue, pain, and 
nausea/vomiting), a global health scale, 5 single items assessing common physical symptoms 
of cancer (dyspnea, loss of appetite, insomnia, constipation, and diarrhoea), and a single item 
assessing the financial effect of cancer. Per the EORTC scoring manual, all raw scores 
obtained from the QLQ-C30 will be transformed to a scale of 0–100; higher scores in the 
functioning and global QoL scales indicating better functioning, and higher scores in the 
symptom scales indicating more problems with the particular symptom being assessed. A

change of  10 points from baseline will indicate a meaningful increase or decrease in the 
specific health related QoL (HEQOL) scale. 
The QLQ-C30 assessment will be supplemented with the BR-23 breast cancer–specific 
questionnaire. This EORTC-developed questionnaire includes 23 questions to assess the 
symptoms and side effects of treatment (surgery, chemotherapy, radiation therapy, and 
hormone), body image, sexuality, and future perspective.  
During the Randomised Expansion phase only; patients will be requested to complete both 
questionnaires at the times indicated in the Study Plan (see Figure 5 and Figure 6) at the 
following timepoints: 
x
Screening. 
x
Cycle 1: Week 1: Day 1: pre-dose. 
x
Every 12 weeks from baseline: at any time of the day and after cessation of study 
therapies up to disease progression or withdrawal of consent.   
x
Discontinuation of AZD5363/placebo: at any time of the day. 
6.5.2 
Administration of EORTC QLQ C-30 and BR-23 questionnaires 
Each centre must allocate the responsibility for the administration of the questionnaires to a 
specific individual (eg, a research nurse, study coordinator) and if possible assign a back-up to 
cover absence.  The AZ Study Delivery Team (or delegate) will provide relevant training in 
administration of the questionnaires.  The paper questionnaire should be administered and 
completed, where possible, at the clinic.  Where this will not be possible, patients will be 
provided with paper copies of the questionnaire to complete at home, and return to the site by 
post. 
It is important that the significance and relevance of the data are explained carefully to 
participating patients so that they are motivated to comply with data collection. 
The instructions for completion of the questionnaires are as follows: 
x
They must be completed prior to any other study procedures (following informed 
consent) and before discussion of disease progress to avoid biasing the patient’s 
responses to the questions. 
x
It must be completed in private by the patient. 
x
The patient should be given sufficient time to complete at their own speed. 
x
The patient should not receive help from relatives, friends or clinic staff to answer 
the questionnaire.  However, if the patient is unable to read the questionnaire the 
questionnaire may be read out by trained clinic staff and responses recorded.

Determination of drug concentration 
Samples for determination of drug concentration in plasma will be analysed by Covance on 
behalf of Clinical Bioanalysis Alliance, AstraZeneca R&D, using appropriate bioanalytical 
methods.  The lower limits of quantification (LLOQ) for AZD5363 and paclitaxel in plasma 
are 1.0ng/mL and 10ng/mL respectively.  Full details of the analytical methods used will be 
described in separate bioanalytical reports. 
All samples still within the known stability of the analytes of interest (AZD5363 and 
paclitaxel) at the time of receipt by the bioanalytical laboratory will be analysed. 
In addition, the pharmacokinetic samples may be subjected to further analyses in order to 
investigate the presence and/or identity of metabolites of AZD5363.  This may involve 
pooling of samples if required.  Any results from such analyses will be reported separately 
from the CSR.

Exploratory biomarker research 
Blood and eyebrow hair will be collected and may be analysed for exploratory biomarkers to 
assess correlations with disease activity, effects of study drug and clinical outcomes.  
Archival tumour samples will be collected for identification of patient PIK3CA mutation 
status (see sections  5.2.1 and  6.2.2) and, where a patient consents, optional paired biopsies 
(see section 6.8.1.3) may also be analysed for exploratory biomarker analysis as outlined 
above.  
The results of this exploratory biomarker research will be reported separately and will not 
form part of the CSR. 
The results of this exploratory biomarker research may be pooled with biomarker data from 
other studies with the study drug to generate hypothese to be tested in future studies.

Samples of CTCs will be shipped under ambient conditions on the day of acquisition so as to 
be received at an AstraZeneca approved laboratory within 72 hours of blood sampling.  
Samples will be collected, labelled, stored and shipped as detailed in the Laboratory Manual. 
6.8.1.2 
Collection of archival tumour samples 
All patients will be asked to provide consent to supply a sample of their most recently 
obtained archival tumour block (tissue derived from the diagnostic tumour or a metastatic site) 
for transfer to the AstraZeneca biobank. 
The tumour sample preferably will be in the form of a formalin-fixed paraffin embedded 
block.  If this is not possible, 10-20 slides of freshly prepared unstained 5 micron sections 
from the archival tumour block may be provided. 
It is anticipated that, where consent is given, remaining tissue samples or slides collected for 
PIK3CA mutation analysis (see section 6.2.2) will be transferred to the biobank.  Samples will 
be disposed of, or returned to the study site dependent upon local requirements, after a 
maximum of 25 years following the Last Patient’s Last Visit in the study. 
6.8.1.3 
Collection of paired tumour biopsies (optional)  
All patients will be asked to provide consent for collection of tumour biopsies.  Where consent 
is given, these samples should be collected at the times presented in the Study Plan (see Figure 
5 and Figure 6): at screening or at pre-dose on Day 1 of Cycle 1 and on Day 1 of Cycle 2 (± 1 
week).  
The samples will be analysed for biomarkers that may influence development of cancers 
and/or response to AZD5363.  The date and time of collection will be recorded in the CRF. 
Samples will be disposed of after a maximum of 25 years following the Last Patient’s Last 
Visit in the study.   
6.8.1.4 
Collection of eyebrow hairs (optional) 
Four eyebrow hairs will be taken at the times presented in the Study Plan (see see Figure 5 
and Figure 6) on each of the timepoints presented in Table 4 and Table 5 below. 
The samples will be analysed for concentrations of exploratory biomarkers which may 
correlate with drug response. The date and time of collection will be recorded in the CRF. 
Samples will be disposed of after a maximum of 25 years following the Last Patient’s Last 
Visit in the study.

Pharmacogenetics 
6.9.1 
Collection of pharmacogenetic samples (optional) 
All patients will be asked to provide consent for collection of a 5mL blood sample 
immediately prior to dosing on Cycle 1: Week 1: Day 1 for genetic research.  Although 
genotype is a stable parameter, early sample collection is preferred to avoid introducing bias 
through excluding patients who may withdraw due to an adverse event (AE), such patients 
would be important to include in any genetic analysis.  If for any reason the sample is not 
drawn at this visit, it may be taken at any other visit until the last study visit.  Only one sample 
should be collected per patient for genetics during the study.  Samples will be collected, 
labelled, stored and shipped as detailed in the Laboratory Manual. 
The results of this pharmacogenetic research will be reported separately and will not form part 
of the CSR. 
Samples will be disposed of after a maximum of 25 years following the Last Patient’s Last 
Visit in the study.   
7. 
BIOLOGICAL SAMPLING PROCEDURES  
7.1 
Volume of blood 
The volume of blood that will be drawn from each patient will vary, dependent upon the 
dosing schedule and phase of the study: 
x
The volume of blood to be drawn from each patient during screening and Cycle 1 
should  not exceed 35 mL and 360 mL respectively 
x
The total volume of blood to be drawn from each patient in the study, assuming 
they complete screening, 6 cycles of combination treatment and a discontinuation 
visit should not exceed 710 mL.   
Safety laboratory assessments will be performed locally at each centre’s laboratory by means 
of their established methods.  The number of samples/blood volumes is therefore subject to 
site-specific change.  
In both phases of the study, extra blood samples may also be collected if, for example, 
additional samples are required for repeat safety assessments or additional PK assessment.

Handling, storage and destruction of biological samples 
The samples will be used up or disposed of after analyses or retained for further use as 
described here. 
Biological samples for future research will be retained by AstraZeneca Alderley Park, UK for 
a maximum of 25 years following the Last Patient’s Last Visit in the study.  The results from 
future analysis will not be reported in the CSR but separately in a Scientific Report. 
7.2.1 
Pharmacokinetic and/or pharmacodynamic / biomarker samples 
Samples will be disposed of after the CSR has been finalised, unless retained for future 
analyses, see below. 
Key samples for investigation of exploratory biomarkers, bioanalytical validation and 
metabolite identification will be retained at AstraZeneca, Alderley Park, UK for a maximum 
of 25 years following the Last Patient’s Last Visit in the study.  The results from the 
investigation will not be reported in the CSR but separately in bioanalytical/metabolism 
reports.

7.2.2 
Pharmacogenetic samples 
The processes adopted for the coding and storage of samples for genetic analysis are 
important to maintain patient confidentiality.  Samples will be stored for a maximum of 15 
years, following the Last Patient’s Last Visit in the study, after which they will be destroyed.  
DNA is a finite resource that may be used up during analyses.  Samples will be stored and 
used until no further analyses are possible or the maximum storage time has been reached. 
For all samples, irrespective of the type of coding used, the DNA will be extracted from the 
blood sample.  The DNA sample will be assigned a unique number, replacing the information 
on the sample tube. Thereafter, the DNA sample will be identifiable by the unique DNA 
number only.  The DNA number is used to identify the sample and corresponding data at the 
AstraZeneca genetics laboratories, or at the designated contract laboratory.  No personal 
details identifying the individual will be available to any person (AstraZeneca employee or 
contract laboratory staff working with the DNA.) 
The samples and data for genetic analysis in this study will be single coded.  The link between 
the patient enrolment/randomisation code and the DNA number will be maintained and stored 
in a secure environment, with restricted access WITHIN the Clinical Genotyping Group 
Laboratory Information Management System (LIMS) at AstraZeneca.  The link will be used 
to identify the relevant DNA samples for analysis, facilitate correlation of genotypic results 
with clinical data, allow regulatory audit and to trace samples for destruction in the case of 
withdrawal of consent when the patient has requested disposal/destruction of collected 
samples not yet analysed. 
7.3 
Labelling and shipment of biohazard samples 
The Principal Investigator ensures that samples are labelled and shipped in accordance with 
the Laboratory Manual and the Biological Substance, Category B Regulations (materials 
containing or suspected to contain infectious substances that do not meet Category A criteria), 
see Appendix C ‘IATA 6.2 Guidance Document’. 
Any samples identified as Infectious Category A materials must not be shipped and further 
samples must not be taken from the patient unless agreed with AstraZeneca, and appropriate 
labelling, shipment and containment provisions are approved. 
7.4 
Chain of custody of biological samples 
A full chain of custody is maintained for all samples throughout their lifecycle. 
The Principal Investigator at each centre keeps full traceability of collected biological samples 
from the patients while in storage at the centre until shipment or disposal (where appropriate) 
and keeps documentation of receipt of arrival when shipped. 
The sample receiver keeps full traceability of the samples while in storage and during use until 
used or disposed of or until further shipment and keeps documentation of receipt of arrival 
when shipped. 

Clinical Study Protocol 
Drug Substance AZD5363  
Study Code D3610C00002 
Edition Number 1 
Date 24 February 2012 
102(131) 
AstraZeneca keeps oversight of the entire life cycle through internal procedures, monitoring of 
study sites and auditing of external laboratory providers. 
Samples retained for further use are registered in the AstraZeneca biobank system during the 
entire life cycle. 
7.5 
Withdrawal of informed consent for donated biological samples 
If a patient withdraws consent to the use of donated biological samples, the samples will be 
disposed of/destroyed, and the action documented.  If samples are already analysed, 
AstraZeneca is not obliged to destroy the results of this research. 
As collection of the biological samples is not regarded as integral to the primary study 
objectives, then the patient may continue in the study. 
The Principal Investigator: 
x
Ensures AstraZeneca is notified immediately of a patient’s withdrawal of informed 
consent to the use of donated samples  
x
Ensures that biological samples from that patient, if stored at the study site, are 
immediately identified, disposed of /destroyed, and the action documented. 
x
Ensures any local laboratory(ies) holding the samples is/are informed about the 
withdrawn consent immediately and that samples are disposed/destroyed, the action 
documented and the signed document returned to the study site. 
x
Ensures that the patient and AstraZeneca are informed about the sample disposal. 
AstraZeneca ensures the central laboratory(ies) holding the samples is/are informed about the 
withdrawn consent immediately and that samples are disposed of/destroyed and the action 
documented and returned to the study site. 
8. 
ETHICAL AND REGULATORY REQUIREMENTS 
8.1 
Ethical conduct of the study 
The study will be performed in accordance with ethical principles that have their origin in the 
Declaration of Helsinki and are consistent with International Conference on Harmonisation 
(ICH)/Good Clinical Practice (GCP), applicable regulatory requirements and the AstraZeneca 
policy on Bioethics and Human Biological Samples. 
8.2 
Patient data protection 
The Informed Consent Form will incorporate (or, in some cases, be accompanied by a 
separate document incorporating) wording that complies with relevant data protection and 
privacy legislation. 

Clinical Study Protocol 
Drug Substance AZD5363  
Study Code D3610C00002 
Edition Number 1 
Date 24 February 2012 
103(131) 
AstraZeneca will not provide individual genotype results to patients, any insurance company, 
any employer, their family members, general physician or any other third party, unless 
required to do so by law. 
Extra precautions are taken to preserve confidentiality and prevent genetic data being linked to 
the identity of the patient. In exceptional circumstances, however, certain individuals might 
see both the genetic data and the personal identifiers of a patient. For example, in the case of a 
medical emergency, an AstraZeneca Physician or an investigator might know a patient’s 
identity and also have access to his or her genetic data. Also Regulatory authorities may 
require access to the relevant files, though the patient’s medical information and the genetic 
files would remain physically separate. 
8.3 
Ethics and regulatory review 
An Ethics Committee (EC) / Investigational Review Board (IRB) should approve the final 
study protocol, including the final version of the Informed Consent Form and any other 
written information and/or materials to be provided to the patients.  The investigator will 
ensure the distribution of these documents to the applicable EC/IRB, and to the study site 
staff. 
The opinion of the EC/IRB should be given in writing. The investigator should submit the 
written approval to AstraZeneca before enrolment of any patient into the study.  
The EC/IRB should approve all advertising used to recruit patients for the study. 
AstraZeneca should approve any modifications to the Informed Consent Form that are needed 
to meet local requirements. 
If required by local regulations, the protocol should be re-approved by the EC/IRB annually. 
Before enrolment of any patient into the study, the final study protocol, including the final 
version of the Informed Consent Form, must be approved by the national regulatory authority 
or a notification to the national regulatory authority must be made, according to local 
regulations. 
AstraZeneca will handle the distribution of any of these documents to the national regulatory 
authorities. 
AstraZeneca will provide Regulatory Authorities, ECs/IRBs and Principal Investigators with 
safety updates/reports according to local requirements, including Suspected Unexpected 
Serious Adverse Reactions (SUSARs), where relevant. 
Where relevant under national requirements; each Principal Investigator is responsible for 
providing the EC/IRB with reports of any serious and unexpected adverse drug reactions from 
any other study conducted with the IP.  AstraZeneca will provide this information to the 
Principal Investigator so that he/she can meet these reporting requirements.

Informed consent 
The Principal Investigator(s) at each centre will: 
x
Ensure each patient is given full and adequate oral and written information about 
the nature, purpose, possible risk and benefit of the study. 
x
Ensure each patient is notified that they are free to discontinue from the study at any 
time. 
x
Ensure that each patient is given the opportunity to ask questions and allowed time 
to consider the information provided. 
x
Ensure each patient provides signed and dated informed consent before conducting 
any procedure specifically for the study. 
x
Ensure the original, signed Informed Consent Form(s) is/are stored in the 
Investigator’s Study File. 
x
Ensure a copy of the signed Informed Consent Form is given to the patient. 
x
Ensure that any incentives for patients who participate in the study as well as any 
provisions for patients harmed as a consequence of study participation are described 
in the Informed Consent Form that is approved by an EC/IRB. 
8.5 
Changes to the protocol and informed consent form 
Study procedures will not be changed without the mutual agreement of the International co-
ordinating Investigator, the Principal Investigator and AstraZeneca. 
If there are any substantial changes to the study protocol, then these changes will be 
documented in a study protocol amendment and where required in a new version of the study 
protocol (Revised Clinical Study Protocol). 
The amendment is to be approved by the relevant EC/IRB and if applicable, also the national 
regulatory authority approval, before implementation.  Local requirements are to be followed 
for revised protocols. 
AstraZeneca will distribute any subsequent amendments and new versions of the protocol to 
each Principal Investigator(s). For distribution to EC see Section 8.3. 
If a protocol amendment requires a change to a centre’s Informed Consent Form, AstraZeneca 
and the centre’s EC/IRB are to approve the revised Informed Consent Form before the revised 
form is used.  
If local regulations require, any administrative change will be communicated to or approved 
by each EC/IRB.

Audits and inspections 
Authorised representatives of AstraZeneca, a regulatory authority, or an EC/IRB may perform 
audits or inspections at the centre, including source data verification.  The purpose of an audit 
or inspection is to systematically and independently examine all study-related activities and 
documents, to determine whether these activities were conducted, and data were recorded, 
analysed, and accurately reported according to the protocol, GCP, guidelines of the ICH, and 
any applicable regulatory requirements.  The investigator will contact AstraZeneca 
immediately if contacted by a regulatory agency about an inspection at the centre.

STUDY MANAGEMENT BY ASTRAZENECA 
9.1 
Pre-study activities 
Before the first patient is entered into the study, it is necessary for a representative of 
AstraZeneca to visit the investigational study site to: 
x
Determine the adequacy of the facilities. 
x
Determine availability of appropriate patients for the study. 
x
Discuss with the investigator(s) (and other personnel involved with the study) their 
responsibilities with regard to protocol adherence, and the responsibilities of 
AstraZeneca or its representatives.  This will be documented in a CSA between 
AstraZeneca and the investigator. 
9.2 
Training of study site personnel 
Before the first patient is entered into the study, an AstraZeneca representative will review and 
discuss the requirements of the Clinical Study Protocol and related documents with the 
investigational staff and also train them in any study specific procedures and systems utilised. 
The Principal Investigator will ensure that appropriate training relevant to the study is given to 
all of these staff, and that any new information relevant to the performance of this study is 
forwarded to the staff involved. 
The Principal Investigator will maintain a record of all individuals involved in the study 
(medical, nursing and other staff). 
9.3 
Monitoring of the study 
During the study, an AstraZeneca representative will have regular contacts with the study site, 
including visits to: 
x
Provide information and support to the investigator(s). 
x
Confirm that facilities remain acceptable.

x
Confirm that the investigational team is adhering to the protocol, that data are being 
accurately and timely recorded in the CRFs, that biological samples are handled in 
accordance with the Laboratory Manual and that study drug accountability checks 
are being performed. 
x
Perform source data verification (a comparison of the data in the CRFs with the 
patient’s medical records at the hospital or practice, and other records relevant to 
the study) including verification of informed consent of participating patients. This 
will require direct access to all original records for each patient (eg, clinic charts). 
x
Ensure withdrawal of informed consent to the use of the patient’s biological 
samples is reported and biological samples are identified and disposed of/destroyed 
accordingly, and the action is documented, and reported to the patient. 
The AstraZeneca representative will be available between visits if the investigator(s) or other 
staff at the centre needs information and advice about the study conduct. 
9.3.1 
Source data 
Refer to the CSA for location of source data. 
9.4 
Study agreements 
The Principal Investigator at each centre should comply with all the terms, conditions, and 
obligations of the CSA, or equivalent, for this study.  In the event of any inconsistency 
between this Clinical Study Protocol and the CSA, the terms of Clinical Study Protocol shall 
prevail with respect to the conduct of the study and the treatment of patients; and in all other 
respects, not relating to study conduct or treatment of patients, the terms of the CSA shall 
prevail. 
Agreements between AstraZeneca and the Principal Investigator should be in place before any 
study-related procedures can take place, or patients are enrolled. 
9.4.1 
Archiving of study documents 
The Investigator follows the principles outlined in the CSA. 
9.5 
Study timetable and end of study 
The end of the study is defined as ‘the last visit of the last patient undergoing the study’. 
The study is expected to start in Q2 2012 and to end by Q4 2014. 
The study may be terminated at individual centres if the study procedures are not being 
performed according to GCP, or if recruitment is slow.  AstraZeneca may also terminate the 
entire study prematurely if concerns for safety arise within this study or in any other study 
with AZD5363.

DATA MANAGEMENT BY ASTRAZENECA 
Data management will be performed by AstraZeneca Data Management Centre staff. 
The data collected through third party sources will be obtained and reconciled against study 
data. 
Adverse events and medical/surgical history will be classified according to the terminology of 
the latest version the Medical Dictionary for Regulatory Activities (MedDRA).  Medications 
will be classified according to the AstraZeneca Drug Dictionary.  All coding will be 
performed by the Medical Coding Team at the AstraZeneca Data Management Centre. 
Data queries will be raised for inconsistent, impossible or missing data.  All entries to the 
study database will be available in an audit trail. 
The data will be validated as defined in the Data Management Plan.  Quality control 
procedures will be applied to each stage of data handling to ensure that all data are reliable 
and have been processed correctly. 
When all data have been coded, validated and locked, clean file will be declared.  Any 
treatment revealing data may thereafter be added and the final database will be locked. 
Data associated with biological samples will be transferred from laboratories internal or 
external to AstraZeneca.  Data from external providers (e.g. central laboratories) will be 
validated as appropriate to ensure it is consistent with the clinical data and included in the 
final database. In the case of biomarker (tumour tissue or blood for exploratory analyses) data, 
only the original date of biopsy (historical tumour tissue sample and the actual date the 
sample(s) were collected) will be recorded in the eCRF and database.  
Any genotype data generated in this study will be stored in the AstraZeneca genotyping LIMS 
database, or other appropriate secure system within AstraZeneca and/or third party contracted 
to work with AstraZeneca to analyse samples.  The results from this genetic research may be 
reported in the CSR for the main study, or in a separate report, as appropriate. 
Some or all of the clinical datasets from the main study may be merged with the genetic data 
in a suitable secure environment separate from the clinical database.

ASTRAZENECA 
11.1 
Calculation or derivation of efficacy variable(s) 
Patients will undergo regular tumour assessments until documented objective disease 
progression as defined by RECIST 1.1 (see Appendix F).

analysis then they will be censored at 0 days for PFS.  Symptomatic deterioration will not be 
regarded as a progression event. 
If a patient discontinues treatment prior to progression and/or receives a subsequent therapy 
prior to progression then these patients will continue to be followed until evidence of 
objective disease progression as defined by RECIST 1.1 and their PFS time will be derived as 
defined above. 
The PFS time will always be derived based on scan/assessment dates not visit dates. 
RECIST assessments/scans contributing towards a particular visit may be performed on 
different dates.  The following rules will be applied: 
x
Date of progression will be determined based on the earliest of the dates of the 
component that triggered the progression. 
x
When censoring a subject for PFS the subject will be censored at the latest of the 
dates contributing to a particular overall visit assessment. 
11.1.5 
Response rate at 12 weeks and best objective tumour response 
Response rate at 12 weeks is defined as the percentage of patients who have a week 12 visit 
response of CR or PR (as defined by RECIST 1.1), regardless of whether the responses are 
confirmed or not. 
Best objective tumour response will be based on RECIST measurements taken throughout the 
whole study and will classify patients as confirmed complete and partial responses as well as 
unconfirmed complete and partial responses, stable disease, progressive disease and not 
evaluable.  ORR is defined as the percentage of patients who have at least one visit response 
of CR or PR prior to any evidence of progression (as defined by RECIST 1.1). 
A visit response of CR is defined when all TL and NTL lesions present at baseline have 
disappeared (with the exception of lymph nodes which must be <10mm to be considered non-
pathological) and no new lesions have developed since baseline.  A visit response of PR is 
defined when the sum of diameters of the TLs has decreased by 30 % or more compared to 
baseline (with no evidence of progression) and the NTLs are at least stable with no evidence 
of new lesions.  
The denominator for response rate calculations will be: all patients dosed for study Part A and 
all randomised patients for study Part B, with the exception of the PIK3CA mutation - positive 
subgroup where the denominator will be all patients dosed / randomised whose tumours test 
positive for the PIK3CA mutation.

111(131) 
11.1.6 
Proportion of patients without progressive disease at 12 weeks 
The proportion of patients without progressive disease at 12 weeks is defined as the 
percentage of patients with a 12 week visit response of CR, PR or SD (as defined by RECIST 
1.1) with no evidence of previous progression.   
The denominator for patients without progressive disease at 12 weeks will be: all patients 
dosed for study Part A and all randomised patients for study Part B. 
11.2 
Calculation or derivation of safety variable(s) 
Safety and tolerability will be assessed in terms of AEs, deaths, laboratory data, vital signs, 
ECG and LVEF.  These will be collected for all patients.  Appropriate summaries of these 
data will be presented as described in Section 12.2. 
ECG Changes 
QTc will be calculated by the Data Management Centre, on behalf of AstraZeneca, using both 
Bazett’s and Fridericia’s formulae. 
Creatinine Clearance 
Estimated creatinine clearance (mL/min) will be calculated using the Cockcroft and Gault 
formula below, from creatinine: 
For creatinine values in mol/L 
Men: [(140 – age) x weight (kg) x 1.23] / creatinine (μmol/L) 
Women: [(140 – age) x weight (kg) x 1.04] / creatinine (μmol/L) 
Corrected Calcium 
Corrected calcium will be calculated using the formula below, from total calcium and 
albumin:  
Corr.  Calcium (mmol/L) = Total Calcium (mmol/L) + ([40 – Albumin (g/L)] x 0.02) 
11.2.1 
Other significant adverse events (OAE) 
During the evaluation of the AE data, an AstraZeneca medically qualified expert will review 
the list of AEs that were not reported as a SAE and/or a Discontinuation of Investigational 
Product due to Adverse Event.  Based on the expert’s judgement, significant adverse events of 
particular clinical importance may, after consultation with the Global Patient Safety Physician, 
be considered OAEs and reported as such in the CSR.  A similar review of laboratory, vital 
signs and ECG data will be performed for identification of OAEs. 
Examples of these are marked haematological and other laboratory abnormalities, and certain 
events that lead to intervention (other than those already classified as serious), dose reduction 
or significant additional treatment.

11.3 
Calculation or derivation of pharmacokinetic variables 
Pharmacokinetic analysis of the plasma concentration data for AZD5363 and paclitaxel will 
be performed by AstraZeneca.  The actual sampling times will be used in the parameter 
calculations and PK parameters will be derived using population pharmacokinetic modelling. 
Where possible, appropriate PK parameters will be reported 
The PK variables for the patients with sparse PK sampling will be estimated using a 
population PK approach.  Details will be included in a separate PK analysis plan. 
11.4 
Calculation or derivation of pharmacodynamic variable(s) 
11.4.1 
Population analysis of pharmacokinetic/pharmacodynamic variables  
The PK, pharmacodynamic, demographic, safety and tumour response data collected in this 
study may also be combined with similar data from other studies and explored using 
population PK and/or PK/PD methods.  The results of any such analyses may be reported 
separately from the CSR. 
11.5 
Calculation or derivation of health related quality of life variables 
(Part B: Randomised expansion only) 
Health related quality of life (HRQoL) and disease-related symptom data will be collected 
using the EORTC QLQ-C30 and BR-23 patient reported outcome (PRO) instruments. 
The QLQ-C30 instrument is composed of both multi-item scales and single-item measures. 
These include five functional scales, three symptom scales, a global health status / QoL scale, 
and six single items. Each of the multi-item scales includes a different set of items - no item 
occurs in more than one scale.  A high scale score represents a higher response level. Thus a 
high score for a functional scale represents a high / healthy level of functioning, a high score 
for the global health status / QoL represents a high QoL, but a high score for a symptom scale 
/ item represents a high level of symptomatology / problems. 
The principle for scoring these scales is the same in all cases.

* Item range is the difference between the possible maximum and the minimum response to individual items; 
† (revised) scales are those that have been changed since version 1.0, and their short names are indicated by a 
suffix “2” – for example, PF2. 
 
The BR-23 instrument comprises 23 questions assessing disease symptoms, side effects of 
treatment (surgery, chemotherapy, radiotherapy and hormonal treatment), body image, sexual 
functioning and future perspective.  The module incorporates five multi-item scales to assess 
systemic therapy side effects, arm symptoms, breast symptoms, body image and sexual 
functioning. In addition, single items assess sexual enjoyment, hair loss and future 
perspective. The scoring approach for the QLQ-BR23 is identical in principle to that for the 
function and symptom scales / single items of the QLQ-C30.

* “Item range” is the difference between the possible maximum and the minimum response to individual items. 
† Items for the scales marked † are scored positively (i.e. “very much” is best) and therefore use the same 
algebraic equation as for symptom scales; however, the Body Image scale uses the algebraic equation for 
functioning scales. 
 
The raw score will be calculated based on the average of the items that contribute to the 
subscale.  A linear transformation will then be applied to the raw score so that visit scores 
range from 0 to 100 (as per the standard coding provided in EORTC scoring manual). 
For missing items within a subscale, if there are >50% of the items in the subscale completed 
then the missing items will be assumed to have values that are equal to the average of the 
items completed.  Otherwise the visit score will be set to missing. 
If there are cases in which more than one questionnaire has been completed on the same day, 
and provide different answers, the questionnaire with the highest overall score will be used. 
Method of categorising visit scores into visit response 
Osoba et al 1998 suggested that in patients with breast and small-cell lung cancer, changes 
(from baseline to various study time points) in scores of 5-10 on a 1-100 scale represented a 
small difference, 10-20 represented a moderate difference, and those above 20 represented 
large differences. King 1996 used a variety of clinical classifications as anchors and found 
similar results across various studies and cancer sites. Based on these 2 studies, mean 
differences of 10 points or more are widely viewed as being clinically significant when 
interpreting the results and hence a cut-off of a chance of 10 points has been used in this study 
to define visit responses of improvements and worsenings.  Visit scores will be categorised 
into visit responses as defined in Table 9.

A deterioration is defined as a visit response of worsened without a visit response of no 
change or improved within 21 days.  If there are no further visit responses available then this 
will still count as deterioration.  Death in the absence of PRO deterioration will also count as 
deterioration if it occurs within 12 weeks of the last evaluable PRO assessment.  Time to 
deterioration is calculated as the time from randomisation to the date of the first assessment at 
which deterioration began.  Subjects that have not deteriorated at the time of data cut off will 
be censored at the time of the last evaluable assessment for that PRO. 
Any subject who cannot possibly worsen compared to baseline will be censored for time to 
worsening at time 0.

STATISTICAL METHODS AND SAMPLE SIZE 
DETERMINATION BY ASTRAZENECA 
12.1 
Description of analysis sets 
12.1.1 
Efficacy analysis set 
All efficacy data in Part B of the study (change in tumour size at 12 weeks, PFS, ORR, DoR 
and percentage of patients without progression at 12 weeks) will be analysed on an intention-
to-treat basis (ITT). This will include all randomised patients, wherever possible, and compare 
treatment groups on the basis of randomised treatment, regardless of the treatment they 
actually received. 
To be considered 'evaluable' for the primary efficacy analysis, a patient must have: 
x
Baseline and week 12 (r1 week) tumour measurements; or 
x
Evidence of progression prior to week 12; or

x
In the absence of the week 12 measurements and no evidence of progression, 
RECIST measurements at baseline and 1 visit after or prior to the week 12 visit 
such that a prediction for the week 12 result can be made (see section 11.1.1 for 
details) 
For the Part A safety run-in, the efficacy analysis set will include all patients who received at 
least one dose of study treatment. 
12.1.2 
Safety analysis set 
All patients who receive at least one dose of AZD5363 in Part A, or randomised treatment in 
Part B, will be included in the assessment of the safety data.  Any patient who only receives 
one or more doses of paclitaxel and does not commence dosing with IP will not be included in 
the assessment of safety data.   
Throughout the safety results sections, erroneously treated patients (e.g., those randomised to 
treatment A but actually given treatment B) will be accounted for in the actual treatment 
group. 
12.2 
Methods of statistical analyses 
A comprehensive statistical analysis plan (SAP) will be prepared prior to enrolment of 
patients in the study. 
The primary outcome variable for Part B of change in tumour size at 12 weeks, and the 
secondary outcome variable of PFS, will be analysed formally.  All Part A data, other Part B 
efficacy and safety data will be summarised descriptively. 
For the primary and secondary analysis the null hypothesis is that there is no treatment effect, 
i.e., there is no difference in terms of change in tumour size at 12 weeks between patients 
treated with AZD5363 + paclitaxel and patients treated with matching placebo + paclitaxel. 
No adjustments for multiplicity will be made. 
Details of sensitivity analyses and imputation methods for missing data will be fully 
documented in the SAP. 
There are potentially a number of different analysis points for the study.  The table below 
details which data will be analysed at each time point.

group whose 12-week data is imputed, will be presented on the footnote to the table of output 
from this analysis. 
The distribution of the tumour size measurement data will be assessed without knowledge of 
the randomised treatment assignment.  If the week 12 changes in tumour size data follow a 
log-normal distribution, these data will be analysed as described previously.  If, however, it is 
judged the data do not adequately follow a log-normal distribution then the use of 
untransformed percentage changes or a non-parametric approach could replace the log 
transformed analysis as the primary approach. 
The week 12 change in tumour size will also be presented graphically by waterfall plots for 
each treatment group which present each patient’s week 12 change in tumour size as a 
separate bar, with the bars ordered from the largest increase to the largest decrease.  This plot 
will be repeated separately by treatment group for those patients whose tumour was PIK3CA 
mutation-positive at entry, and also for the overall analysis but flagging (by colour or pattern) 
whether patients are PIK3CA mutation-positive or not detected.  Reference lines at the +20% 
and -30% change in tumour levels will be added to the plots, which correspond to the changes 
in sum of TLs that would result in the TL responses of progression and partial response, 
respectively.  In these waterfall plots (and also in the listings) the patients whose week 12 
change in tumour size is based on an imputation due to missing TL data but known to be 
progressors will be clearly identified (by different coloured bars for the waterfall plots and a 
flag in the listings). 
Change in tumour size will be presented descriptively for patients in Part A of the study with 
summary tables and waterfall plots.   
Frequencies of NTL progressions and new lesions at week 12 will be presented together with 
the change in tumour size results in order to put the change in tumour size results into 
perspective. 
12.2.2 
Progression Free Survival 
The secondary endpoint of PFS will be analysed for the patients in Part B when recruitment to 
Part B has completed and approximately 45 PFS events in the overall population have 
occurred.  Waiting until recruitment has completed to this part of the study will ensure that as 
many as possible of the PFS events included in the analysis come from a mixture of PIK3CA 
mutation positive and not detected patients.  This aims to safeguard against the possibility that 
the progression events could be largely from the mutation not detected patients if that stratum 
recruits substantially quicker than the other.  PFS will not be presented for patients in Part A 
of the study.  PFS will be analysed for the overall population and for the subgroup of PIK3CA 
mutation patients, using separate Cox proportional-hazards models allowing for the effect of 
treatment and including a term for PIK3CA mutation status in the overall analysis (mutation 
positive or not detected). 
The hazard ratios in the overall population and in the PIK3CA mutation subgroup (HR; 
AZD5363 + paclitaxel: placebo + paclitaxel) for treatment will be estimated together with

and schedule for patients in Part A.  For Part B, the main set of safety tables will consist of the 
overall population in the randomised expansion, but a reduced set of key safety outputs will 
also be repeated on patients with PIK3CA mutation positive tumours (as according to 
stratification levels determined at randomisation) to assess if the safety profile remains 
consistent within these patients. 
Adverse Events 
Data from all cycles of initial treatment will be combined in the presentation of the safety 
data.  AEs will be listed individually by patient and treatment group (dose and schedule group 
for the safety run-in phase).  For patients who undergo a dose modification, all AEs (due to 
drug or otherwise) will be assigned to the initial dose group. 
The number of patients experiencing each AE will be summarised by the Medical Dictionary 
for Regulatory Activities (MedDRA) system organ class, MedDRA preferred term and 
CTCAE grade.  The number and percentage of patients with adverse events in different 
categories (AEs, SAEs, AE with outcome death, CTCAE grade 3, AEs leading to permanent 
discontinuation) will be summarised by treatment group, and events in each category will be 
further summarised by MedDRA system organ class and preferred term, by treatment group.  
An additional table of all preferred terms sorted by decreasing frequency will be produced to 
show most frequent AEs regardless of system order class. 
Any AE occurring before the first dose of IP (i.e., before Cycle 1 Week 1 Day 2) will be 
included in the data listings but will not be included in the summary tables of adverse events. 
Any AE occurring within the defined 28 day follow-up period after discontinuation of study 
therapy (AZD5363/placebo and/or paclitaxel) will be included in the AE listings and 
summaries. AEs occurring after the 28-day follow-up period after discontinuation of IP will 
be listed separately, but not included in the summaries. 
Laboratory parameters, vital signs and physical examination data 
Laboratory parameters will be listed and summarised over time in terms of absolute values 
and change from baseline. 
Corrected calcium will be derived by AstraZeneca. 
CTCAE grades will be calculated for laboratory parameters, where possible.  Where CTCAE 
grading is available, a table of 1-grade shift, 2-grade shifts, 3-grade shifts and 4-grade shifts, 
in maximum CTC grade will be produced for each laboratory parameter, to summarise the 
overall worst CTCAE grade over the course of the study compared to the baseline CTCAE 
grade.  Where possible, the direction of the shift will be reported to put the shift into context 
of an event such as hyper- or hypo- clinical event.  Box and whisker plots of lab parameters 
against time will also be produced.  
Vital signs (SBP, DBP and pulse) will be listed and box plots of change from baseline in SBP, 
DBP and pulse will be presented.

12.2.6 
Pharmacokinetics  
Part A Safety Run-in AZD5363 and paclitaxel pharmacokinetics 
Plasma concentrations of AZD5363 and paclitaxel will be summarised by nominal sample 
time.  Plasma concentrations and derived PK parameters will be summarised by dose level and 
schedule.  Plasma concentrations at each time point will be summarised according to dose and 
schedule by the following summary statistics: 
x
The geometric mean (gmean, calculated as exp [ȝ], where ȝ is the mean of the data 
on a logarithmic scale) 
x
Coefficient of variation (CV, calculated as 100 ¥ [exp(s2)-1], where s is the standard 
deviation of the data on a log scale)

will be presented according to the following rules: 
x
If, at a given time point, 50% or less of the plasma concentrations are non-
quantifiable (NQ), the geometric mean (gmean), CV, gmean ± standard deviation 
(SD), arithmetic mean, SD and median will be calculated by substituting the LLOQ 
for values which are NQ.  The minimum at that time point will be reported as NQ.

Summary statistics of time to deterioration for each score using Kaplan-Meier 
estimates 
If sufficient data is collected to warrant further statistical analyses, analysis of time to 
deterioration of PRO scores will be considered by a log rank test to estimate hazard ratios and 
confidence intervals for the effect of treatment on each of the scores.  Kaplan-Meier plots and 
estimates of median time to deterioration will also be produced.  Likewise, if there is 
sufficient data and initial explorations warrant further exploration with statistical analyses, the 
use of repeated-measure analysis of variance models will be considered treating each of the 
scores as continuous endpoints and estimating the effect of treatment on the changes in scores 
over time. 
12.2.9 
Exploratory biomarkers and pharmacogenetics 
The number of patients that will agree to participate in the exploratory biomarker and genetic 
research is unknown.  Therefore, it is not possible to establish whether sufficient data will be 
collected to allow a formal statistical evaluation, or whether only descriptive statistics will be 
generated. 
12.3 
Interim analyses 
An interim analysis will be performed when 40 patients have been recruited to Part B and 
followed up for 12 weeks (or progressed prior to 12 weeks).  The analysis will be primarily 
based on changes in tumour size at 12 weeks, but additional summaries of response rate at 12 
weeks, proportion progression-free at 12 weeks and best objective response during the study 
will support the change in tumour size data at the interim analysis.  The analysis and data 
presentations will be performed on the overall population, no PIK3CA mutation subgroup 
analysis will be performed as the number of patients expected to be recruited with a PIK3CA 
mutation positive tumour by that stage is likely to be low. 
The purpose of the interim analysis is to provide the opportunity for an early trigger to 
commence setting up a phase IIb study, if the results are strong enough, such that once the 
primary analysis is completed to confirm the interim result, the phase IIb study could 
commence with minimal delay.  Therefore, as safety data will be analysed on the full dataset 
at the primary analysis, it is proposed not to include safety data at the interim analysis.  It is 
not considered necessary to adjust the significance level to account for this additional analysis 
of the data, given that this analysis will not form the basis of any stop or acceleration 
decisions. In addition, the results obtained will be interpreted with caution, bearing in mind 
the increased risk of false positive results that this additional analysis introduces.

Determination of sample size 
Part B - Randomised expansion 
The primary endpoint of change in tumour size at week 12 will be assessed by calculating the 
log of the ratio of the week 12 (r1 week) tumour size measurement over the baseline tumour

 IMPORTANT MEDICAL PROCEDURES TO BE FOLLOWED 
BY THE INVESTIGATOR 
13.1 
Medical emergencies and AstraZeneca contacts 
The Principal Investigator is responsible for ensuring that procedures and expertise are 
available to handle medical emergencies during the study. A medical emergency usually 
constitutes an SAE and is to be reported as such, see Section 6.4.4 
In the case of a medical emergency the investigator may contact the Study Delivery Team 
Leader. If the Study Delivery Team Leader is not available, contact the Study Delivery Team 
Physician at AstraZeneca Alderley Park, UK.

Overdose  
There is no known antidote to AZD5363.  Investigators should be advised that any patient 
who receives a higher dose than intended should be monitored closely, managed with 
appropriate supportive care and followed up expectantly. 
Such overdoses should be recorded as follows: 
x
An overdose with associated AEs is recorded as the AE diagnosis/symptoms on the 
relevant AE modules in the CRF and on the Overdose CRF module. 
x
An overdose without associated symptoms is only reported on the Overdose CRF 
module.

Edition Number 1 
Date 24 February 2012 
128(131) 
If an overdose of AZD5363/placebo occurs in the course of the study, then investigators or 
other site personnel must inform appropriate AstraZeneca representatives within one day, ie, 
immediately but no later than the end of the next business day 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 with associated SAE, standard reporting timelines apply, see Section 6.4.4.  For 
other overdoses, reporting should be done within 28 days. 
For treatment of overdose with paclitaxel, please refer to the local prescribing information.  
Overdose of paclitaxel with associated AEs/SAEs should be recorded in the relevant AE/SAE 
module of the eCRF and reported according to the standard timelines.  The overdose does not 
need to be entered in to the overdose eCRF module. 
13.3 
Pregnancy 
All outcomes of pregnancy should be reported to AstraZeneca. 
13.3.1 
Maternal exposure 
If a patient becomes pregnant during the course of the study IP should be discontinued 
immediately. 
Pregnancy itself is not regarded as an adverse event unless there is a suspicion that the IP 
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 patient was discontinued from the study. 
If any pregnancy occurs in the course of the study, then investigators or other site personnel 
must inform appropriate AstraZeneca representatives within one day ie, immediately but no 
later than the end of the next business day 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 
days for SAEs, see Section 6.4.4 and within 28 days for all other pregnancies. 
The same timelines apply when outcome information is available. 
The PREGREP module in the CRF is used to report the pregnancy and the PREGOUT is used 
to report the outcome of the pregnancy.

Sponsor:  
AstraZeneca AB, 151 85 Södertälje, Sweden.  
Centres affected by the Amendment: 
All centres within the study. 
The protocol for the study is to be amended as detailed below:  
It was identified that standard AstraZeneca protocol text describing reporting times for 
Serious Adverse Events (SAEs) had become non-compliant under European Directive 2011/C 
172/01 (CT-3) ‘Detailed guidance on the collection, verification and presentation of adverse 
event/reaction reports arising from clinical trials on medicinal products for human use’ section 
4.3.1 paragraph 29. 
Protocol Edition 1 stated SAE reporting time from the Investigator to the Sponsor 
as: ‘immediate but no later than the end of the next business day’.  
The European Directive states: ‘Immediate reporting should allow the sponsor to 
take the appropriate measures to address potential new risks in a clinical trial. 
Therefore, the immediate report should be made by the investigator within a very

short period of time and under no circumstances should this exceed 24 hours 
following knowledge of the serious adverse event.’. 
The Study D3610C00002 protocol will therefore be amended to revise the criterion of ‘no 
later than the end of next business day’ to ‘within 24 hours’.  This criterion will be applied to 
reporting of SAEs, overdose and maternal exposure: 
 
The protocol for the study is to be amended as follows (revised text in bold):

Clinical Study Protocol Amendment 2 
Drug Substance AZD5363 
Study Code D3610C00002 
Date 24 April 2013 
2(85) 
1. 
Study Title and phase of development:  Part B of this study had been re-
categorised from Phase Ib to Phase II in reflection of an increase in the size of the 
study and change to progression-free survival as primary endpoint; as detailed in 
item 3 below. 
2. 
Study Part A.  Replacement of AZD5363 continuous dosing schedule with an 
intermittent dosing schedule:  The original design of Part A of this study 
comprised two dosing schedules of AZD5363 in combination with paclitaxel: 
Schedule 1 -  AZD5363 continuous dosing, and Schedule 2 - AZD5363 intermittent 
dosing [weekly - 4 days on-therapy followed by 3 days off].   
Schedule 1 was not initiated in response to findings from associated clinical trial 
D3610C00001 - that an AZD5363 monotherapy continuous dosing schedule may 
not present a sufficiently favourable tolerability  profile.  It is proposed to now 
replace the Schedule 1 continuous regimen with an AZD5363 intermittent dosing 
regimen [weekly - 2 days on-therapy followed by 5 days off] following a strong 
pre-clinical positive evidence of efficacy of this schedule and an adequate clinical 
safety and tolerability profile as monotherapy in study D3610C00001. 
3. 
Study Part B.  Increase of total patient number enrolled from 60 to 100 and 
change of primary endpoint to progression-free survival:   The original design 
of Part B was to provide statistical power to detect a difference in change of tumour 
size in the overall population and in the PIK3CA tumour mutation-positive 
subgroup.  The study was also powered to detect a difference in progression-free 
survival (PFS) in the overall population, but not in the PIK3CA tumour mutation-
positive subgroup.   
Given the hypothesis that patients with a PIK3CA tumour mutation are the most 
likely to benefit from study therapy, it is proposed to increase the total number of 
patients to ensure sufficient statistical power to detect a potential difference in PFS 
in the PIK3CA tumour mutation-positive subgroup as well as in the overall 
population.  This would provide for a more robust evaluation of AZD5363 
combined with weekly paclitaxel, compared with weekly paclitaxel plus placebo, 
upon which to develop subsequent studies. 
As a result of this change, the primary objective for Part B has been revised from 
assessment of relative anti-tumour activity (endpoint variable - change in tumour 
size at 12 weeks) to assessment of relative efficacy (endpoint variable - progression-
free survival).  Assessment of relative anti-tumour activity has become a secondary 
objective. 
4. 
Study Part B.  Addition of overall survival as a secondary endpoint:  Overall 
survival has been added as a secondary endpoint in this study to provide an initial 
assessment of the survival time after treatment with AZD5363 combined with 
weekly paclitaxel compared with weekly paclitaxel plus placebo.  This will provide 
essential guidance to inform the design of subsequent studies.

5. 
Study Part B.  Extension of WHO performance status evaluations:  Further 
performance status assessments at visits from first receipt of study drug up to 
progression will be performed.  This has been implemented following guidance 
received from the UK  National Institute for Health and Care Excellence (NICE) for 
studies of similar design. 
6. 
Study Part B.  Introduction of an independent Safety Review Committee:  The 
inclusion of an SRC, with membership that is independent of participation in Study 
D3610C00002, is being implemented to enable periodic review of coded 
randomised trial data outputs.  The SRC will assess safety and tolerability findings 
and will provide recommendations regarding continuation, adjustment or cessation 
of the dose and schedule of AZD5363/placebo. 
7. 
Study Part B.  Provision for a change in AZD5363/placebo formulation:   
Allowance will be made for a potential switch in AZD5363/placebo formulation 
from capsules to tablets prior to the start of, or during, Part B.  The implementation 
of a tablet formulation would allow data to be generated from patients who have 
received a dosage form consistent with that of the likely on-market formulation.  
Such a change would be made only following the generation of data from study 
D3610C00001 demonstrating that PK exposure from the new tablet formulation is 
comparable to that of the original capsule formulation.  Any such change would 
also be subject to the agreement of the SRC. 
8. 
Study Part B.  Revision of statistical analysis plans:  The scheduling and conduct 
of statistical analyses will be revised to reflect the increase in patient numbers, 
change in primary objective and addition of overall survival evaluation under the 
scope of this protocol amendment 
9. 
Study Parts A and B.  Inclusion of a Japanese patient population:  Under the 
original protocol it was not envisaged that Japan would participate in Part B, but 
that an optional dose escalation evaluation in Japanese patients could be conducted 
under Part A if indicated.  It is now anticipated that Japanese patients will 
participate in Part B and be treated with the same doses of AZD5363 and paclitaxel 
as those in the West.  This is based on the observation that Japanese patients are 
known to tolerate the required dose of paclitaxel and that no significant differences 
in PK and tolerability of AZD5363 have been observed between the Western and 
Japanese patients who have participated in AZD5363 Studies D3610C00001 and 
D3610C00004 respectively.  In the event that emerging findings from Part B 
indicate a difference between the two populations in terms of tolerability, the 
Japanese dose escalation subsidiary Part A may be conducted at the request of the 
Safety Review Committee.  In this case, enrolment of Japanese patients to Part B 
would be suspended.

General Revisions 
1. 
References to a ‘continuous’ dosing schedule have been replaced by ‘intermittent’ 
or ‘intermittent 2-on 5-off’ throughout the amended protocol (please see 
amendment rationale number 2).  Where these occur as solitary text changes only, 
they are not listed separately in this amendment. 
2. 
References to AZD5363/placebo ‘capsule’ formulation for study Part B have been 
replaced by ‘capsule or tablet’ throughout the amended protocol (please see 
amendment rationale number 7).  Where these occur as solitary text changes only, 
they are not listed separately in this amendment. 
3. 
References to suspension of AZD5363/placebo dosing being permitted for single 
periods of up to 28 days due to suspected toxicities have been replaced by up to 14 
days throughout the amended protocol and Appendix H (Instructions for study drug 
dose modification).  After which time study therapy should be withdrawn.  This 
change aligns with a more stringent approach to management of toxicities 
implemented across the AZD5363 clinical studies.  Where these replacements occur 
as solitary text changes only, they are not listed separately in this amendment.   
4. 
In the original protocol - Common Terminology Criteria for Adverse Events 
(CTCAE) version 4.1 was referenced in error.  This has been corrected to version 
4.0  throughout the amended protocol.  Where these replacements occur as solitary 
text changes only, they are not listed separately in this amendment. 
5. 
References to retention of samples by AstraZeneca for a maximum of 25 years for 
conduct of  bioanalytical research have been revised to a maximum of 15 years 
throughout the amended protocol.  This amendment has been made following a 
change in AstraZeneca’s Maximum Retention Period for Human Biological 
Samples policy.   Where these replacements occur as solitary text changes only, 
they are not listed separately in this amendment.

AZD5363 has been shown to greatly increase sensitivity to the taxane docetaxel (Taxotere) in 
several breast cancer xenograft models.  For example, both continuous and intermittent 
schedules of AZD5363 enhanced the efficacy of docetaxel in the HCC-1187 xenograft (Figure 
1).  The sequence of administration appears to be very important; in the HCC-1187 model, 
administering docetaxel after an intermittent dosing schedule of AZD5363 (4 days on, 3 days 
off) was found to be antagonistic, whilst administering docetaxel before the intermittent 
schedule resulted in enhanced efficacy  (Figure 2).

levels (Figure 3). 
 
Additional Figure: 
Figure 3 
Different dosing schedules of AZD5363 deliver equivalent efficacy, as 
monotherapy or in combination with taxotere, in the BT474c xenograft 
model. 
In this model, a dose of 255 mg/kg bd of AZD5363 combined with Taxotere given in a 2 
days on 5 days off intermittent schedule delivers equivalent efficacy to that obtained 
from a combination of Taxotere with either 150mg/kg bd of AZD5363 given in a 
continuous schedule and 210mg /kg bd of AZD5363 given in a 4 days on, 3 days off

The patient population will be female, aged 18 years or older, with advanced or metastatic 
breast cancer.  For inclusion in Part A, patients must not have received any more than two 
prior courses of chemotherapy for breast cancer.  Prior endocrine therapy is allowed. 
Patients will be recruited in approximately 8 centres in approximately 4 countries.  The 
number of patients enrolled will be dependent upon the number of dose escalation cohorts 
required, see below, but a total of approximately 40 patients is anticipated.

Intermittent dosing:  AZD5363 capsules taken orally, twice daily, for repeating weekly 
cycles of 4 days on treatment followed by 3 days off treatment during each week that 
paclitaxel is received.  The starting dose for cohort 1 will be 360 mg (720 mg daily).   
Dose escalating cohorts of 3 to 6 patients will be evaluated under each schedule.  A total of 6 
patients must be evaluated at a selected dose level for it to be confirmed as the RD.  AZD5363 
dose escalations and maximum doses attained will not exceed levels deemed tolerated by the

1.  
Part A - Safety Run-in phase only: Patients will continue to undergo paclitaxel PK measurements on these occasions. 

Clinical Study Protocol Amendment 2 
Drug Substance AZD5363 
Study Code D3610C00002 
Date 24 April 2013 
38(85) 
2.  
RECIST, MUGA/Echo, CTCs, Glycosylated haemoglobin, lipids and QoL to be conducted every 12 weeks from start of treatment (Cycle 1 Day 1).  Part 
B - Randomised expansion only: Patients will continue to undergo RECIST assessments after cessation of study therapies up to disease progression or 
withdrawal of consent.   
3.  
WHO performance status; Part B – Randomised expansion phase only:  Performance status will be assessed at these timepoints during part B 
only. 
4.  
Insulin c-peptide; Part A - Safety Run-in phase only:  Insulin c-peptide will not be analysed during the Part B Randomised expansion. 
5. 
Part B Randomised expansion phase only: Survival status and subsequent cancer therapies will be determined at the 28 day follow-up visit and 
at 12-weekly intervals thereafter.  These visits suggested to coincide with RECIST assessments up to disease progression, and at 12-weekly 
intervals thereafter to death or withdrawal. 
 
Reason for Amendment:  
Please see amendment rationale number 2 regarding replacement of the schedule of assessments relevant to the AZD5363/placebo 
continuous dosing regimen – with a schedule relevant to the intermittent (2 days-on, 4 days-off) dosing regimen.    
Addition of a survival status evaluation for study Part B has been introduced with reference to amendment rationale number 4. 
Reasons for other amendments to timepoints and footnotes are described per assessment for protocol sections 6.4.5 to 6.8.1.6  
detailed later in this document.

RECIST, MUGA/Echo, CTCs, Glycosylated haemoglobin, lipids and QoL to be conducted every 12 weeks from start of treatment (Cycle 1 Day 1). Part 
B Randomised expansion only: Patients will continue to undergo RECIST assessments after cessation of study therapies up to disease progression or 
withdrawal of consent.   
3.  
WHO performance status; Part B – Randomised expansion phase only:  Performance status will be assessed at these timepoints during part B 
only. 
4. 
Insulin c-peptide; Part A - Safety Run-in phase only:  Insulin c-peptide will not be analysed during Part B. 
5. 
Part A Safety Run-in phase only: Patients will undergo the Cycle 2 Week 1 Day 1 MUGA / Echocardiogram assessment during Part A only.  
This assessment timepoint will not be conducted during the Part B Randomised expansion. 
6. 
Part B Randomised expansion only: Survival status and subsequent cancer therapies will be determined at the 28 day follow-up visit and at 12-
weekly intervals thereafter.  These visits suggested to coincide with RECIST assessments up to disease progression, and at 12-weekly intervals 
thereafter to death or withdrawal. 
 
Reason for Amendment:  
Sample timepoints (pre-, post- dosing and number of hours post-dosing where applicable) have been specified in the schedules of 
assessments for clarity following feedback received from study sites. 
Addition of a survival status evaluation for study Part B has been introduced with reference to amendment rationale number 4. 
Reasons for other amendments to timepoints and footnotes are described per assessment for protocol sections 6.4.5 to 6.8.1.6 
detailed later in this document.

Exposure to potent inhibitors or inducers of CYP3A4 or substrates of CYP3A4 or 
CYP2D6 within 2 weeks before the first dose of study treatment (3 weeks for St John’s 
Wort). 
Reason for Amendment:  
The original text was incorrect due to a typographic error in a source document.  This 
amendment reflects that CYP2D6 is not inducible, and exposure to inhibitors of CYP2D6 
should not be an exclusion.  However, AZD5363 is a moderate competitive inhibitor of 
CYP2D6, therefore substrates of CYP2D6 are restricted.

The Principal Investigator will: 
1. 
Obtain signed informed consent from the potential patient before any study specific 
procedures are performed. 
2. 
Obtain a unique enrolment number, beginning with ‘E#’. The E-code is a 7-digit number 
comprising the centre number, the dosing schedule and the patient number within that 
particular centre.  This number is the patient’s unique identifier and is used to identify 
the patient on the electronic case report form (eCRF), and should be entered in to the 
patient medical records.  The E-code will be in the format E000WXYZ.  Where 000W= 
site number, X = schedule (1 = Part A continuous, 2 = part A intermittent, 3 = Part B), Y 
& Z = patient number (per schedule) e.g., the first patient screened at centre 0001, to the 
Part A continuous dosing schedule would be assigned the E-code - E0001101, the 
second patient - E0001102; the first patient at this site in the Part A intermittent dosing 
schedule would be E0001201.  
Once a candidate patient has been identified and consented, the site should obtain the 
enrolment number as follows: 
 Part A: For the safety run-in phase, the study site will notify the AstraZeneca Study 
Team that a patient has been consented by completion and e-mailing of a registration 
form.  AstraZeneca will reply, providing the E  number.  For Part A this will include 
notification of which dosing schedule the patient is allocated to.  
Part B:  For the randomised expansion phase, the study site will contact the Interactive 
Voice/Web Response System (IVRS/IWRS) by telephone or using the web to notify that 
a patient has consented.  IVRS/IWRS will provide the E  number. 
Further guidance on this process will be provided in a separate patient allocation process 
document.  
All screened patients are assigned an E-code and will be listed on the patient enrolment 
and identification log irrespective of whether or not they subsequently receive study 
therapy.  If a patient withdraws from participation in the study, their E-code will not be 
reused and the patient will not be allowed to re-enter the study.   
For the Randomised Expansion part, if the patient is not randomised the site should 
notify IVRS/IWRS via a Discontinuation Call to enable the termination of the

Part A: For the safety run-in phase, the study site will notify the AstraZeneca Study 
Team that a patient is eligible by completion and e-mailing of a registration form.  
AstraZeneca will reply, providing the identification code.  The first patient entering 
cohort 1 of schedule 1 (continuous dosing) will be numbered 1001, the second will be 
1002 and so on.  Patients assigned to schedule 2 (intermittent dosing) will be 2001, 2002 
onwards.   
Part B:  For the randomised expansion phase, the study site will contact the IVRS/IWRS 
by telephone or using the web to confirm whether the patient is/is not eligible and, if 
eligible, to report the PIK3CA mutation status: ‘positive’ or ‘not detected’ (see section 
5.2.1) to enable stratification.  IVRS/IWRS will provide the randomised identification 
code.  Patients that are PIK3CA mutation positive will be numbered 3001, 3002 
onwards.  Those that are PIK3CA mutation not detected will be numbered 4001, 4002 
onwards.  The treatment randomisation will not be indicated under this system. 
It is requested that sites obtain the randomised identification code on the day that the 
patient is ready to commence treatment.   
Further guidance on this process will be provided in a separate patient allocation process 
document.  Procedures will be provided in an IVRS/IWRS user manual that will be 
provided to each centre. 
If a patient withdraws from participation in the study, then her identification code cannot 
be reused. 
Revised text: 
The Principal Investigator will: 
1. 
Obtain signed informed consent from the potential patient before any study specific 
procedures are performed. 
2. 
Obtain a unique enrolment (‘E’) number – which will be automatically generated by 
the RAVE system once initial patient information has been entered.  This E-code is 
a 7-digit number comprising the country code, centre number, the dosing schedule and 
the patient number within that particular centre.  This number is the patient’s unique 
identifier and is used to identify the patient on the electronic case report form (eCRF), 
and should be entered in to the patient medical records.  The E-code will be in the 
format EAB0WXYZ.  Where AB = country code, 0W= site number, X = schedule (1 = 
Part A intermittent [2-on 5-off], 2 = Part A intermittent [4-on 3-off], 3 = Part B), Y & 
Z = patient number (per schedule)  
e.g., the first patient screened in the UK (country code = 28) at centre 01, to 
the Part A intermittent 2-on 5-off dosing schedule would be assigned the E-
code – E2801101, the second patient – E2801102.  The first patient at this site 
in the Part A intermittent 4-on 3-off dosing schedule would be E2801201.

Once a candidate patient has been identified and consented, the site should provide 
notification as follows: 
Part A: For the safety run-in phase, the study site will notify the AstraZeneca Study 
Team that a patient has been consented by completion and e-mailing of a registration 
form.  AstraZeneca will reply, providing confirmation of the dosing schedule that the 
patient has been assigned to. Upon entry of this into the appropriate database in 
the eCRF, the patient E-code will be generated automatically by the RAVE system. 
Part B:  For the randomised expansion phase, the study site will contact the Interactive 
Voice/Web Response System (IVRS/IWRS) by telephone or using the web to notify that 
a patient has consented. 
Further guidance on this process will be provided in a separate patient allocation process

Previous text: 
Patient stratification by PIK3CA mutation status (Part B) 
Patients will be stratified to PIK3CA mutation positive’ or ‘PIK3CA mutation not detected’ 
arms prior to randomisation.  
Patients assigned a PIK3CA mutation status of ‘Unknown’ will not be eligible to participate in 
Part B. In cases where an archival tumour sample is not received in time to be analysed by the 
central laboratory during screening, defined status may be derived from the blood sample 
alone, or it may be applicable to utilise the status from a prior, locally-conducted tumour 
analysis, see above. 
If a patient is initially stratified to the ‘Not detected’ arm based upon a blood sample alone, or 
blood sample plus locally–conducted tumour analysis, and a subsequent, delayed, tumour 
sample is ‘positive’  the stratification will not be changed but the discrepancy will be noted.  
Any requirement to assign additional patient places to either stratification arm will be

Revised text: 
Patient stratification by PIK3CA mutation status (Part B) 
Patients will be allocated to ‘PIK3CA mutation positive’ or ‘PIK3CA mutation not detected’ 
strata prior to randomisation.  
Patients assigned a PIK3CA mutation status of ‘Unknown’ will not be eligible to participate in 
Part B. In cases where an archival tumour sample is not received in time to be analysed by the 
central laboratory during screening, defined status may be derived from the blood sample 
alone, or it may be applicable to utilise the status from a prior, locally-conducted tumour 
analysis, see above. 
If a patient is initially stratified to the ‘Not detected’ stratum based upon a blood sample 
alone, (or blood sample plus locally–conducted tumour analysis) and a ‘positive’ central 
tumour sample analysis is received after stratification, the site will contact the 
IVRS/IWRS Customer Care department by telephone or using the web to provide 
notification of this new information.  IVRS/IWRS records will be revised to show a 
corrected PIK3CA mutation status of ‘Positive’.   
In the event of any correction to a patient’s allocated mutation status post-stratification: 
x
there will be no revision to the patient stratum allocation or numbering in RAVE. 
x
AZ will coordinate with IVRS/IWRS to ensure that the allocation of patient places 
per stratum is adjusted, as necessaary, to ensure that the minimum number 
required in each will be achieved 
x
for final data analysis the corrected mutation status will be used to assign the 
patient to the relevant stratum.  
Reason for Amendment:  
Clarification of patient stratification terminology – replacing ‘arm‘ with ‘stratum’.  
Statement of process and procedure in the event that the initially recorded PIK3CA tumour-
mutation status of a patient is revised following subsequent tumour sample analysis.

During the conduct of Part B, the SRC will continue to evaluate the status of patients 
ongoing in Part A (see section 5.10.2).  If emerging findings suggest that the AZD5363 
dosing schedule that was not selected to commence Part B may present a more 
favourable alternative - in terms of safety, tolerability and/or efficacy – they may elect to 
re-start Part B under this schedule in consultation with AstraZeneca.     
In this circumstance, recruitment to the original dose schedule for Part B would cease, 
and 100 patients would be recruited to the new dose schedule. 
Reason for Amendment:  
With reference to amendment rationale number 6; this addition allows for the Part B dose 
and/or schedule of AZD5363/placebo to be revised under guidance from the Safety Review 
Committee within the parameters of assessments conducted under Part A.

approximately 3-monthly intervals.  Based on this coded review, the independent SRC 
may recommend one of: a) continuation of recruitment without change; or b) an 
amendment to the dose and schedule of AZD5363/placebo eg, from a 4 days on, 3 days 
off schedule to a 2 days on, 5 days off schedule or to continue at the same schedule at a 
reduced dose of AZD5363/placebo; or c) termination of recruitment on the grounds that 
the combination is considered to be insufficiently well tolerated. 
The independent SRC will consist of: 
x
AstraZeneca Physician, independent of the AZD5363 programme, who will chair 
the committee - or delegate 
x
AstraZeneca Global Safety Physician, independent of the AZD5363 programme. 
x
Two external Investigators independent of the study 
The independent SRC Remit document for this study will define the exact membership 
and who should be present for decisions to be made. 
The first review of coded safety data will occur when data are available from 
approximately 15 patients who have received at least 28 days of treatment.  
In the event that AstraZeneca adopts the recommendation to explore an alternative dose 
or schedule, any patients already recruited to the study at this point will continue to 
receive AZD5363/placebo as per their current dose and schedule provided that they are 
tolerating the treatment and the investigator believes they are gaining benefit.  
Alternatively, the investigator may elect to change the dose/schedule of patients 
recruited prior to the dose change to the new dose/schedule.  After a change to the 
schedule of AZD5363/placebo, approximately 100 new patients will be recruited to 
receive AZD5363/placebo as per the new schedule. There will be no more than 2 changes 
made to dose or schedule during the randomised phase of the study.

off.  The patient does not have to attend the clinic for the survival assessments to be 
carried out; these can either be done via a telephone call, or through review of the 
patient’s notes, or through the use of public records.  If the site becomes aware that a 
patient has died prior to the primary analysis, the relevant eCRF on the database should 
be completed at that time. 
To aid the interpretation of the survival analysis, anti-cancer therapies administered 
following the discontinuation of study treatment will be recorded on the eCRF.

The volume of blood to be drawn from each patient during screening and Cycle 1 should  
not exceed 35 mL and 360 mL respectively 
x
The total volume of blood to be drawn from each patient in the study, assuming they 
complete screening, 6 cycles of combination treatment and a discontinuation visit should 
not exceed 710 mL.   
Safety laboratory assessments will be performed locally at each centre’s laboratory by means 
of their established methods.  The number of samples/blood volumes is therefore subject to

Revised text: 
The volume of blood that will be drawn from each patient will vary, dependent upon the 
dosing schedule and phase of the study: 
x
The volume of blood to be drawn from each patient during screening and Cycle 1 should 
not exceed 35 mL and 380 mL respectively 
x
The total volume of blood to be drawn from each patient in the study, assuming they 
complete screening, 6 cycles of combination treatment and discontinuation visits should 
not exceed 750 mL.   
Safety laboratory assessments will be performed locally at each centre’s laboratory by means 
of their established methods.  The number of samples/blood volumes is therefore subject to 
site-specific change.  
In both phases of the study, extra blood samples may also be collected if, for example, 
additional samples are required for repeat safety assessments or additional PK assessment.

Reason for Amendment:  
Amendments reflect: Additional glucose 4-6 hour post-dose samples, revision of the reference 
treatment schedule from continuous to intermittent 4 days-on, 3 days-off, AZD5363/placebo 
dosing - and correction of an omission under the original protocol, which had failed to include 
sample volumes collected during Cycles 4 to 6.

The primary outcome variable for Part B of the study is change in tumour size at 12 weeks.  
This is based on RECIST measurements taken at baseline and at week 12.  Tumour size is the 
sum of the longest diameters of the TLs that have been selected at baseline.  Baseline for 
RECIST is defined to be the last evaluable assessment prior to starting treatment.  The change 
in tumour size will be assessed using the log (ratio) of the week 12 tumour size over the 
baseline tumour size for each subject.  More details on TLs selection and assessment during 
the treatment can be found in Appendix F of the protocol.

Section of protocol affected: 
Section 12.1.1.  Efficacy analysis set. 
Previous text: 
All efficacy data in Part B of the study (change in tumour size at 12 weeks, PFS, ORR, DoR 
and percentage of patients without progression at 12 weeks) will be analysed on an intention-
to-treat basis (ITT). This will include all randomised patients, wherever possible, and compare 
treatment groups on the basis of randomised treatment, regardless of the treatment they 
actually received. 
To be considered 'evaluable' for the primary efficacy analysis, a patient must have: 
x
Baseline and week 12 (r1 week) tumour measurements; or 
x
Evidence of progression prior to week 12; or 
x
In the absence of the week 12 measurements and no evidence of progression, RECIST 
measurements at baseline and 1 visit after or prior to the week 12 visit such that a 
prediction for the week 12 result can be made (see section 11.1.1 for details) 
For the Part A safety run-in, the efficacy analysis set will include all patients who received at 
least one dose of study treatment.

and compare treatment groups on the basis of randomised treatment, regardless of the 
treatment they actually received. 
For the Part B randomised expansion; in the event that the dose/schedule is changed 
following recommendation by the SRC, and the total number of patients has been 
increased to compensate for patients recruited prior to the change, the primary analyses 
will be performed on the subset of the efficacy analysis set randomised to the new

patients in the study. 
The primary outcome variable for Part B of change in tumour size at 12 weeks, and the 
secondary outcome variable of PFS, will be analysed formally.  All Part A data, other Part B 
efficacy and safety data will be summarised descriptively. 
For the primary and secondary analysis the null hypothesis is that there is no treatment effect, 
i.e., there is no difference in terms of change in tumour size at 12 weeks between patients 
treated with AZD5363 + paclitaxel and patients treated with matching placebo + paclitaxel. 
No adjustments for multiplicity will be made. 
Details of sensitivity analyses and imputation methods for missing data will be fully 
documented in the SAP. 
There are potentially a number of different analysis points for the study.  The table below

many as possible of the PFS events included in the analysis come from a mixture of PIK3CA 
mutation positive and not detected patients.  This aims to safeguard against the possibility that 
the progression events could be largely from the mutation not detected patients if that stratum 
recruits substantially quicker than the other.  PFS will not be presented for patients in Part A

12.3.  Interim analyses 
Previous text: 
An interim analysis will be performed when 40 patients have been recruited to Part B and 
followed up for 12 weeks (or progressed prior to 12 weeks).  The analysis will be primarily 
based on changes in tumour size at 12 weeks, but additional summaries of response rate at 12 
weeks, proportion progression-free at 12 weeks and best objective response during the study 
will support the change in tumour size data at the interim analysis.  The analysis and data 
presentations will be performed on the overall population, no PIK3CA mutation subgroup 
analysis will be performed as the number of patients expected to be recruited with a PIK3CA 
mutation positive tumour by that stage is likely to be low. 
The purpose of the interim analysis is to provide the opportunity for an early trigger to 
commence setting up a phase IIb study, if the results are strong enough, such that once the 
primary analysis is completed to confirm the interim result, the phase IIb study could 
commence with minimal delay.  Therefore, as safety data will be analysed on the full dataset 
at the primary analysis, it is proposed not to include safety data at the interim analysis.  It is 
not considered necessary to adjust the significance level to account for this additional analysis 
of the data, given that this analysis will not form the basis of any stop or acceleration 
decisions. In addition, the results obtained will be interpreted with caution, bearing in mind 
the increased risk of false positive results that this additional analysis introduces.

mutation subgroups have been achieved and 30 PIK3CA mutation-positive patients have  
completed 12 week follow up period (or progressed prior to 12 weeks).   
The 2nd interim analysis will be conducted upon all efficacy outputs other than survival 
for the overall population (including PIK3CA mutation-positive subgroup analyses for

size measurement for each patient.  If the patient has documented evidence of objective 
disease progression prior to week 12, then this will be used as the week 12 measurement.

Centres affected by the Amendment: 
This amendment affects all centres in the study 
The protocol for the study is to be amended as follows:  
Changed or additional text is indicated in bold, where applicable. Deleted text is indicated as 
scored through. 
Administrative changes - due to, for example, correction of typographical errors or 
renumbering of subsequent sections following addition of new sections - have been amended 
as applicable and have been included in the revised protocol but will not be listed separately in 
this amendment. 
The protocol amendments defined within this document primarily relate to the areas detailed, 
with rationales, below.  Other amendments are described separately in the body of this 
document. 

Clinical Study Protocol Amendment 3 
Drug Substance AZD5363 
Study Code D3610C00002 
Date 09 May 2014 
2(79) 
1. 
Part B Inclusion Criteria:  

Addition of requirement for patients to be negative for presence of Human 
Epidermal Growth Factor Receptor 2 (HER2) for entry to Part B of this study.  This 
change was to reflect that HER2 – positive patients would be de-facto excluded 
from the study due to non-allowance of anti-HER2 agents in combination, and is for 
the purposes of clarity rather than significantly altering the intended patient 
population. 

Removal of requirement for patients to have received prior endocrine therapy for 
entry to Part B.  This change was made following Investigators’ identification that 
this criterion prevented access to study treatment for otherwise applicable patients.  
On review, AstraZeneca concluded that receipt of prior endocrine therapy would 
not present a critical factor in the interpretation of trial outcomes and that allowing 
entry of patients without such prior therapies would not confer additional risks to 
patient safety or welfare. 
2. 
Part B Patient Stratification: Allowance included for patients to be allocated to 
PIK3CA tumour mutation ‘positive’ or ‘not detected’ strata based upon central 
laboratory analysed and/or pre-existing local laboratory analyses.  Allowance is also 
given for patients to be allocated to the ‘not detected’ stratum as a default option 
where no PIK3CA tumour mutation status results available at the time of planned 
start of standard care / study treatment.  This change was made in response to 
Investigators concerns that the period required for provision and analysis of both a 
patient’s blood and tissue samples for central determination of their PIK3CA tumour 
mutation status could result in a clinically unacceptable delay to the commencement 
of study and standard of care treatment (i.e would take longer than the time required 
to complete other screening procedures).  This change therefore allows Investigators 
to ensure that patients may be stratified and commmence study therapy without 
incurring delay;  based upon the best available information, or in the absence of 
information. Additional changes to enrolment procedures are also included to ensure 
that appropriate numbers of patients with/without PIK3CA mutation of their tumour 
are included in the study and that randomisation balance is maintained within each of 
these two study strata: 

In instances where a patient may be allocated to the ‘not-detected’ stratum, 
and the PIK3CA tumour mutation is subsequently identified as ‘positive’, 
the patient’s status will be amended accordingly in the study database and 
the corrected status utilised for all analyses. 

In the event that recruitment to one stratum is completed before the other, 
this change will provide clarity regarding a process to close the completed 
stratum to further recruitment and to pre-screen patients for mutation status 
applicable to the remaining, open, stratum 
3. 
Efficacy Variable: Durable Response Rate added as new efficacy variable.  This 
change was made to enable an assessment of the proportion of patients who had a 

Clinical Study Protocol Amendment 3 
Drug Substance AZD5363 
Study Code D3610C00002 
Date 09 May 2014 
3(79) 
sustained response of at least 24 weeks.  Whilst the primary outcome of the study is 
the standard endpoint of progression-free survival, from which a positive result may 
be obtained if patients benefit from an extended duration of stable disease; durable 
response rate allows analysis of the presence and durable effect of any anti-tumour 
activity arising from the combination of AZD5363 with paclitaxel chemotherapy 
which could not be measured by assessing only response rate. 
4. 
Part B Patient Assessments: Reduction in the number of patient assessments, and 
the number of days on which patients are required to attend for evaluation.  This 
change was made in response to Investigators’ observations that the originally 
proposed schedule of assessments presented a potential burden to both patients and 
site staff.  Whilst all assessments are acceptable and essential for the Phase I (Part A) 
evaluation, the data that the removed assessments would provide were - on further 
review- not considered fundamental for the Phase II evaluation of Part B; nor were 
they essential for the purposes of maintaining patient safety.   
It was also noted that the schedule of assessments during Cycle 1, Week 1 – requiring 
patients to attend on Day 3 (and 5 for those on the 4 days-on, 3 days-off regimen) 
post commencement of dosing - resulted in it being necessary to initiate the study on 
particular days of the week in order to avoid assessments being required on non-
working days.  This restricted the ability of study sites to provide the most 
appropriate timetable for patient attendance for initiation and subsequent evaluations.  
On consideration of the above, AstraZeneca has concluded that it is appropriate to 
remove Part B patient evaluations on Cycle 1 Week 1 Days 3 and 5 and on Week 4 of 
Cycles 1 and 2; with some re-assignment of specific assessments.  This was based on 
the judgement that sufficient data will be collected during Part A at these timepoints 
to support study endpoints and objectives, when combined with a reduced and 
revised evaluation set from Part B.  It was considered that anticipated benefit in ease 
of study conduct for sites and patients mitigated against reduction in overall data 
collection. 
5. 
Data Monitoring Committee.  Inclusion of an AstraZeneca internal Data 
Monitoring Committee (AZDMC).  This change was made following a review of 
interim data analysis requirements for study Part B.  From this it was identified that 
blinded data evaluation alone by the Safety Review Committee may be insufficient to 
adequately evaluate patient safety and initial efficacy indicators in the event of any 
outcomes that may require amendment to study conduct.  In addition, the introduction 
of the AZDMC would ensure that the AZ personnel directly involved in the running 
of the study would not be involved in reviewing the data from the interim analyses 
and therefore limits any potential for bias in study conduct after each of the interim 
analyses. 
The members of the AZDMC will be AstraZeneca personnel independent of the 
AZD5363 project team.  Their remit will be to evaluate unblinded data outputs 
following Part B 1st and 2nd interim analyses and provide the project team with

recommendations for action with respect to study conduct and the management of 
patients treated under the auspices of the study protocol. 
 
It is the judgement of the AstraZeneca Project Team that none of the protocol changes detailed 
in this document present any additional risk or hazard to participating patients welfare or 
safety.

Section of protocol affected: 
Protocol Synopsis: Study Design / Part B: Randomised Expansion 
Additional text (following paragraph 2): 
Patients may be stratified based upon PIK3CA status determined by a central laboratory 
(Quintiles) and/or an existing PIK3CA status determined by local analysis.  In instances 
where the period required for provision and analysis of both a patient’s blood and tissue 
samples for central determination of their PIK3CA tumour mutation status would result 
in a clinically unacceptable delay to the commencement of study and standard of care 
treatment (i.e will take longer than the time required to complete other screening 
procedures), the patient may be stratified to the ‘not-detected’ arm by default in the 
absence of a known status. In such cases, where the PIK3CA tumour mutation status is 
subsequently identified as ‘positive’, the record of the patient’s status will be amended 
accordingly in the study database and the corrected status utilised for all analyses.

Revised text: Note 1 – the following tables now represent patient assessments as applicable to Part A of the study only.  These 
assessments remain unchanged from protocol edition 2.  All changes are therefore relevant to removal of assessments applicable to 
Part B alone (which are now shown in new Figure 9).  For clarity of presentation, the revised schedules of assessment and 
footnotes are shown below without marked deletions.  The individual changes are described in the relevant sections identified 
under the ‘Details in Section:’ column. 
Note 2 - a ’12 weekly’ column has been included to more clearly identify assessments relevant to the set of evaluations conducted at 
12-weekly intervals and to delineate these from assessments conducted routinely at the start of each Cycle.

Reason for Amendment:  
Revision to reflect Part A assessments only - Please refer to amendment rationale number 4. 
Addition of a ’12 weekly’ column followed feedback received from study sites that delineation of evaluations between  those to be 
conducted at the start of each cycle from Cycle 3 onwards and those to be conducted at 12-weekly intervals from baseline, was 
insufficiently clear in the original protocol versions.

3. 
Circulating tumour cell samples will be collected on Cycle 3 Week 1 Day 1 and then only at 12-weekly assessments thereafter (see footnote 2 above). 
4. 
Survival status and subsequent cancer therapies will be determined at the 28 day follow-up visit and at 12-weekly intervals thereafter.  These visits

Section 5.2.1 Procedure for identification of tumour PIK3CA mutation status and 
stratification. 
Previous text: 
Determination of PIK3CA mutation status 
Blood (for cfDNA) and most recent archival tumour samples should be provided at screening 
for determination of  PIK3CA mutation status (see section 6.2.2) 
Where possible, samples should be collected no later than two weeks prior to intended first 
dosing date.  Samples will be analysed by Quintiles on behalf of AstraZeneca and the results 
reported to the study site within 7-14 days of transfer.  
Patients will be designated as:‘PIK3CA mutation positive’ or ‘PIK3CA mutation not detected’. 
Where a sample cannot be analysed, or the analysis is flawed/indeterminate, a status of 
‘unknown’ will be reported.  The results from both the blood and tumour analyses will be 
utilised to derive a single ‘defined’ PIK3CA mutation status for each patient with reference to 
the algorithm below.  
Part A. Safety Run-In: Defined PIK3CA mutation status is not a requirement for 
commencement of treatment, but should be recorded prior to completion of Cycle 1. 
Part B. Randomised Expansion: Defined PIK3CA mutation status is required prior to 
commencement of treatment for stratification of patients to PIK3CA mutation-positive and 
mutation–not detected groups (see ‘Patient stratification by PIK3CA mutation status’ below).  
If it is not possible to obtain one, or both, sample types at screening, the missing sample(s) 
must be provided no later than the end of Cycle 1.

Note: 
Pre-existing PIK3CA mutation status, where generated from a relevant tumour 
sample as part of local clinical practice, will also be recorded. These data may be 
utilised, if necessary, on study completion to assist in confirmation of mutation

status where there is a discrepancy between blood and tumour PIK3CA mutation 
results from the central analysis.  
Where an archival tumour sample cannot be provided in sufficient time for analysis 
by Quintiles to support determination of defined PIK3CA mutation status (Part B) 
or the result is ‘unknown’ (Part A or B), mutation status derived from a prior 
locally-conducted analysis may be utilised.  This, however, will only be acceptable 
where the analytical methodology/kit has been approved in advance by

Patients will be allocated to ‘PIK3CA mutation positive’ or ‘PIK3CA mutation not detected’ 
strata prior to randomisation.  
Patients assigned a PIK3CA mutation status of ‘Unknown’ will not be eligible to participate in 
Part B. In cases where an archival tumour sample is not received in time to be analysed by the 
central laboratory during screening, defined status may be derived from the blood sample 
alone, or it may be applicable to utilise the status from a prior, locally-conducted tumour 
analysis, see above. 
If a patient is initially stratified to the ‘Not detected’ stratum based upon a blood sample alone, 
(or blood sample plus locally–conducted tumour analysis) and a ‘positive’ central tumour 
sample analysis is received after stratification, the site will contact the IVRS/IWRS Customer 
Care department by telephone or using the web to provide notification of this new 
information.  IVRS/IWRS records will be revised to show a corrected PIK3CA mutation status 
of ‘Positive’.   
In the event of any correction to a patient’s allocated mutation status post-stratification: 
x
there will be no revision to the patient stratum allocation or numbering in 
RAVE. 
x
AZ will coordinate with IVRS/IWRS to ensure that the allocation of patient 
places per stratum is adjusted, as necessaary, to ensure that the minimum 
number required in each will be achieved 
x
for final data analysis the corrected mutation status will be used to assign the 
patient to the relevant stratum.

Determination of PIK3CA mutation status 

Clinical Study Protocol Amendment 3 
Drug Substance AZD5363 
Study Code D3610C00002 
Date 09 May 2014 
35(79) 
Blood (for cfDNA) and most recent archival tumour samples should be provided at screening 
for determination of  PIK3CA mutation status (see section 6.2.2).  For Part B, in the event 
that recruitment to one stratum is completed before the other, it will be necessary to pre-
screen patients for mutation status applicable to the remaining open stratum (see section 
5.2.2 and Figure 9). 
Where possible, samples should be collected no later than two weeks prior to intended first 
dosing date.  Samples will be analysed by Quintiles on behalf of AstraZeneca and the results 
reported to the study site within 7-14 days of transfer.  
Patients will be designated as:‘PIK3CA mutation positive’ or ‘PIK3CA mutation not detected’. 
Where a sample cannot be analysed, or the analysis is flawed/indeterminate, a status of 
‘unknown’ will be reported.  The results from both the blood and tumour analyses will be 
utilised to derive a single ‘defined’ PIK3CA mutation status for each patient with reference to 
the following algorithm below.

Part B. Randomised Expansion: Defined PIK3CA mutation status is required prior to 
commencement of treatment for stratification of patients to PIK3CA mutation positive and 
mutation not detected groups (see ‘Patient stratification by PIK3CA mutation status’ below).  
If it is not possible to obtain one, or both, sample types at screening, the missing sample(s)

Pre existing PIK3CA mutation status, where generated from a relevant tumour 
sample as part of local clinical practice, will also be recorded. These data may be 
utilised, if necessary, on study completion to assist in confirmation of mutation 
status where there is a discrepancy between blood and tumour PIK3CA mutation 
results from the central analysis.  
Where an archival tumour sample cannot be provided in sufficient time for analysis 
by Quintiles to support determination of defined PIK3CA mutation status (Part B) 
or the result is ‘unknown’ (Part A or B), mutation status derived from a prior 
locally conducted analysis may be utilised.  This, however, will only be acceptable 
where the analytical methodology/kit has been approved in advance by 
AstraZeneca. 
Patients must be stratified to either the PIK3CA mutation-positive or mutation–not 
detected arm prior to randomisation and commencement of treatment.  
All efforts should be made to provide plasma and tumour tissue samples for PIK3CA 
mutation analysis during the screening period*.  However, patients may be stratified in 
the absence of mutation status results from one or both sample types (see below) where 
the investigator considers this necessary to minimise delay to commencement of 
standard treatment with paclitaxel.  Any samples not collected during screening must be 
provided for analysis no later than the end of Cycle 1. 
Investigators may register a patient’s PIK3CA tumour mutation status via IVRS/IWRS 
to enable stratification and randomisation - at a time appropriate to start of study 
therapy.  PIK3CA tumour mutation status will be identified and stratification may be 
conducted under the following conditions, dependent upon availability of PIK3CA 
mutation results from either mandated central laboratory (Quintiles) analysis or pre-
existing local tumour tissue analysis (please also refer to Figure 9): 
Patient stratification by PIK3CA mutation status (Part B) 
Patients will be allocated to ‘PIK3CA mutation positive’ or ‘PIK3CA mutation not detected’ 
strata prior to randomisation.  
Patients assigned a PIK3CA mutation status of ‘Unknown’ will not be eligible to participate in 
Part B. In cases where an archival tumour sample is not received in time to be analysed by the 
central laboratory during screening, defined status may be derived from the blood sample 
alone, or it may be applicable to utilise the status from a prior, locally conducted tumour 
analysis, see above. 
Patient will be identified as PIK3CA ‘positive’ in either/both of the following cases:  

Available centrally analysed plasma and/or tumour tissue sample results are 
PIK3CA ‘positive’ (Note: where both sample types have been sent for central 
analysis, stratification may be based on the first result to be returned). 

Clinical Study Protocol Amendment 3 
Drug Substance AZD5363 
Study Code D3610C00002 
Date 09 May 2014 
37(79) 

Locally analysed plasma and/or tumour tissue result is positive for any 
PIK3CA mutation.  
Patient will be identified as PIK3CA ‘not detected’ in either of the following cases**:  

Available centrally analysed plasma and tumour tissue sample results are 
PIK3CA ‘not detected’ and any locally analysed tumour tissue sample result is 
negative for PIK3CA mutation.   

Centrally analysed plasma or tumour tissue sample results are awaited, but not 
yet available, and no locally analysed tumour tissue sample results are 
available, at the planned time of stratification.  In this case the patient may be 
stratified to the ‘not detected’ group by default.  Note - at least the plasma 
sample must have been received by the central laboratory before the patient 
may be stratified/randomised. 
* In the event that only one stratum is open to recruitment, see section 5.2.2 and Figure 9 
scenario 2, patients will be separately evaluated for PIK3CA mutation status prior to 
screening to determine eligibility.  In such a case, the status derived for eligible patients 
will be carried forward to be recorded under the screening assessment. 
**If  Where a patient is initially stratified to the ‘Not detected’ stratum based upon a blood 
sample alone, (or blood sample plus locally–conducted tumour analysis) in the absence of 
one or more sample analyses, and a ‘positive’ central tumour sample analysis result is 
received after stratification, the site will contact the IVRS/IWRS Customer Care department 
by telephone or using the web to provide notification of this new information.  IVRS/IWRS 
records will be revised to show a corrected PIK3CA mutation status of ‘Positive’.   
In the event of any correction to a patient’s allocated mutation status post-stratification: 
x
there will be no revision to the patient stratum allocation or numbering in RAVE. 
x
AZ will coordinate with IVRS/IWRS to ensure that the allocation of patient places per 
stratum is adjusted, as necessary, to ensure that the minimum number required and 
radomisation balance within each will be achieved. 
x
for final data analysis the corrected mutation status will be used to assign the patient to 
the relevant stratum.

delay.  Where paclitaxel is ceased entirely, it is recommended that AZD5363/placebo 
may be is continued on a weekly schedule at the investigator’s discretion (see section 
5.5.4). 
Reason for Amendment:  
Following Investigator comments regarding preferred clinical management of patients 
remaining on AZD5363/placebo after having ceased paclitaxel.  This change provides further 
emphasis upon a recommendation to continue such patients under a weekly AZD5363/placebo 
treatment schedule – i.e. 4 weeks per cycle rather than 3 weeks on-treatment followed by 1 
week-off.

Additional text (new 3rd paragraph): 
If paclitaxel is permanently ceased, and the investigator elects to continue provision of 
AZD5363/placebo, it is recommended that the 3 weeks-on, 1 week-off dosing schedule is 
changed to a weekly dosing schedule – i.e AZD5363/placebo may be taken on every week 
during a cycle, with no requirement for an off-treatment week.  This change remains at 
the discretion of the investigator. Please note that irrespective of any change to the 
overall inter-weekly treatment schedule, the intra-weekly schedule (eg 4 days-on, 3 days-
off or 2 days-on, 5 days-off) should be retained. 
Reason for Amendment:  
Please see rationale provided for changes to Section 5.5.3 above. 
 
Section of protocol affected: 
Section 5.10.2 Safety Review Committee and Dose Escalation Process  
Additional text (new final paragraph): 
The SRC will continue to evaluate Part A patients after the dose decision for the last 
cohort has been made, up to a point at which all patients have completed three treatment 
cycles or have withdrawn from the study prior to the end of Cycle 3.  No further routine 
evaluations will then be performed by the Part A SRC; although members may be 
requested to attend ad-hoc meetings for discussion of specific safety issues that may 
arise. 
Reason for Amendment:  
Following agreement with the Part A Safety Review Committee, this addition provides clarity 
regarding the processes and timelines for their evaluation of patient safety up to and following 
completion of Part A recruitment. 
 
Section of protocol affected: 
Section 5.11.2 Safety Review Committee (Part B) 
Previous text: 
During the Part B Randomised Phase of the study, an independent SRC will monitor safety 
and tolerability in the study by means of coded (A vs B) reviews of safety data at 
approximately 3-monthly intervals.  Based on this coded review, the independent SRC may 
recommend one of: a) continuation of recruitment without change; or b) an amendment to the 
dose and schedule of AZD5363/placebo eg, from a 4 days on, 3 days off schedule to a 2 days 
on, 5 days off schedule or to continue at the same schedule at a reduced dose of

Study Code D3610C00002 
Date 09 May 2014 
42(79) 
AZD5363/placebo; or c) termination of recruitment on the grounds that the combination is 
considered to be insufficiently well tolerated. 
The independent SRC will consist of: 
x
AstraZeneca Physician, independent of the AZD5363 programme, who will chair the 
committee - or delegate 
x
AstraZeneca Global Safety Physician, independent of the AZD5363 programme. 
x
Two external Investigators independent of the study 
The independent SRC Remit document for this study will define the exact membership and 
who should be present for decisions to be made. 
The first review of coded safety data will occur when data are available from approximately 
15 patients who have received at least 28 days of treatment.  
In the event that AstraZeneca adopts the recommendation to explore an alternative dose or 
schedule, any patients already recruited to the study at this point will continue to receive 
AZD5363/placebo as per their current dose and schedule provided that they are tolerating the 
treatment and the investigator believes they are gaining benefit.  Alternatively, the investigator 
may elect to change the dose/schedule of patients recruited prior to the dose change to the new 
dose/schedule.  After a change to the schedule of AZD5363/placebo, approximately 100 new 
patients will be recruited to receive AZD5363/placebo as per the new schedule. There will be 
no more than 2 changes made to dose or schedule during the randomised phase of the study. 
Revised text: 
During the Part B Randomised Phase of the study, an independent SRC (ISRC) will monitor 
safety and tolerability in the study by means of coded (A vs B) reviews of safety data at 
approximately 3 to 6-monthly intervals.  Based on this coded review, the independent ISRC 
may recommend one of: a) continuation of recruitment without change; or b) an amendment 
to the dose and schedule of AZD5363/placebo eg, from a 4 days on, 3 days off schedule to a 2 
days on, 5 days off schedule or to continue at the same schedule at a reduced dose of 
AZD5363/placebo; or c) termination of recruitment on the grounds that the combination is

It is requested that all efforts are made to ensure that archival tumour tissue is provided 
for this stratification analysis.  Where tissue cannot be made available in a timely 
manner, PIK3CA mutation stratification may be conducted on the blood sample

mutation analysis prior to completion of treatment Cycle 1.   
x
Where a patient has been assigned to the not-detected arm from blood sample analysis 
alone but the retrospective tumour tissue analysis is PIK3CA mutation positive - the 
patient will remain stratified to the not-detected arm.  The discrepancy will be noted 
and an additional patient allocation may be made for this arm.

In the event that one stratification arm (PIK3CA mutation positive or not-detected) 
completes recruitment before the other, new candidate patients will be requested to 
provide separate, initial, informed consent to obtain a blood and/or tumour tissue 
sample to screen for PIK3CA mutation status.  Patients with status appropriate for 
entry to the open stratification arm will be invited to provide informed consent for 
entry to the study.

Section 6.2.2 PIK3CA Mutation Status   
Previous text: 
Patient response to treatment will be assessed against the tumour PIK3CA mutation status to 
determine whether the mutation confers any increased tumour sensitivity to AZD5363. 
Blood and most recent archival tumour samples will be collected at screening (see Figure 6 
and Figure 7) with reference to the criteria and restrictions detailed in section 5.2.1.  The 
PIK3CA mutation assay(s) will genotype for a set of mutations that will cover the majority of, 
but not all, mutations in the PIK3CA gene that have been thus far identified in breast cancer 
patients.  Therefore, there may be patients carrying either a rare mutation, not included in the 
assay(s) used, or who have a level of mutation in cfDNA or tumour tissue DNA beyond the 
range of sensitivity of the selected assay(s).  In this case, their mutation will not be identified 
under the protocolled testing.  In acknowledgment of this, patients who are shown not to be

‘mutation positive’ in either cfDNA or tumour tissue DNA will be categorised as ‘mutation 
not detected’, rather than a more definitive ‘mutation negative’. 
During Study Part B, PIK3CA mutation status will be utilised to stratify patients to ‘positive’ 
and ‘not detected’ arms (see section 5.2.1). 
Revised text: 
Patient response to treatment will be assessed against the tumour PIK3CA mutation status to 
determine whether the mutation confers any increased tumour sensitivity to AZD5363. 
A 10ml blood sample and most recent archival tumour samples will be collected at screening 
(see Figure 6, and Figure 7 and Figure 8) with reference to the criteria and restrictions 
detailed in section 5.2.1.  The PIK3CA mutation assay(s) will genotype for a set of mutations 
that will cover the majority of, but not all, mutations in the PIK3CA gene that have been thus 
far identified in breast cancer patients.  Therefore, there may be patients carrying either a rare

patients who are shown not to be ‘mutation positive’ in either cfDNA or tumour tissue DNA 
will be categorised as ‘mutation not detected’, rather than a more definitive ‘mutation 
negative’. 
During Study Part B, PIK3CA mutation status will be utilised to stratify patients to ‘positive’ 
and ‘not detected’ arms (see sections 5.2.1 and 5.2.2 and Figure 9). 
An optional 20mL blood sample will also be taken, subject to separate patient consent, to 
be utilised for evaluation of innovative PIK3CA mutation analysis platforms.  The 
purpose of this evaluation is to evaluate new analytical options for enhanced specificity, 
accuracy and/or increased speed of sample processing. 
Reason for Amendment:  
Clarification of blood sample volume and inclusion of an optional 20ml sample for evaluation 
of PIK3CA analytical platforms.  This change was made to allow for collection of a voluntary 
blood sample to be used to assess new analytical technologies that may enable more rapid 
and/or more accurate measurement of PIK3CA tumour mutations.  Further clarity is given 
regarding volumes to differentiate between this optional sample and the mandatory blood 
sample for screening PIK3CA analysis.

Volume of blood 
Previous text: 
The volume of blood that will be drawn from each patient will vary, dependent upon the 
dosing schedule and phase of the study: 
x
The volume of blood to be drawn from each patient during screening and Cycle 1 
should not exceed 35 mL and 380 mL respectively 
x
The total volume of blood to be drawn from each patient in the study, assuming they 
complete screening, 6 cycles of combination treatment and discontinuation visits 
should not exceed 750 mL.   
Safety laboratory assessments will be performed locally at each centre’s laboratory by means 
of their established methods.  The number of samples/blood volumes is therefore subject to 
site-specific change.  
In both phases of the study, extra blood samples may also be collected if, for example, 
additional samples are required for repeat safety assessments or additional PK assessment.

The plasma concentrations, determined using the sparse PK sampling scheme data will 
be analyzed using population non-linear mixed effects approach (Beal and Sheiner 1988-
1998). If data from the current study proves limited and is identified as insufficient to 
define the pharmacokinetics (large standard errors, non-identifiable PK profile), 
additional data will be included from previous clinical studies. Parameters will include 
AUCss, Cmaxss, CL/F and other PK parameters will be determined where appropriate 
and possible.  
Once the population PK model is defined, covariates (age, weight, renal function etc) 
relationship and it's clinical relevant to the model will be explored.  
The population PK analysis of data from this study will form part of the overall 
population analysis for the AZD5363 programme and is described in a population PK 
analysis plan associated with this programme. 
Reason for Amendment:  
Clarification and simplification of parameters for analysis of pharmacokinetic data.   
Inclusion of an option to combine data with outputs from other AZD5363 clinical studies in 
the event that PK outputs from D3610C00002 prove to be insufficient to enable a sufficiently 
robust evaluation.

Not applicable  
In addition to the ISRC (see section 5.11.2) Part B of the study will utilise an 
AstraZeneca internal Data Monitoring Committee (AZDMC), that is independent of the 
AZD5363 project team, to evaluate unblinded data outputs following the 1st and 2nd 
interim analyses (see section 12.3). The AZDMC will provide the project team with 
recommendations for action with respect to study conduct and the management of 
patients treated under the auspices of the study protocol. The AZDMC may recommend 
that the study should continue as planned, be terminated or modified in some way. It is 
then the responsibility of AZ to act as appropriate upon AZDMC recommendations 
concerning safety and study conduct. 
The AZDMC is constituted of: 
 
x
Head of Early Clinical Development, or delegate, who serves as the 
chairperson of the AZDMC 
x
Head of Biometrics in Early Clinical Development  
x
Head of Innovative Medicines and Early Development 
x

Centres affected by the Amendment:
This amendment affects all centres in the study.
Primary reason for amendment:
To allow the use of the tablet formulation of AZD5363 in Part A patients.  
In response to feedback from Investigators and emerging clinical data, other substantial 
changes have also been made to the protocol. These changes will simplify procedures, aid 
participation and adherence to the protocol, without compromising patient care.
Persons who initiated the Amendment:
AstraZeneca clinical study team. 
For details of all revised text in each section of the protocol, refer to the revised protocol (and 
tracked change version of the revised protocol) submitted with this amendment.

Where deleted, additional or amended protocol text is included in this amendment document it 
has been presented in italic script to aid ease of identification.
Primary protocol change in this amendment: 
1.
5.5.3 Doses and treatment regimens: Changes have been made to the text to 
permit the use of dose-equivalent tablets in Part A of the study, as current wording 
specifies capsules only.  This is supported by data generated from study 
D3610C00007 and is presented in Edition 6 of the Investigator’s Brochure.  The 
data show the comparability of PK exposure and safety between the original capsule
(of the kind that has been dosed to patients in Part A of the study) and the new 
tablet formulation of AZD5363.  
Other substantial protocol changes in this amendment:
1.
Part B Patient Assessments: Changes to and an overall reduction in the number of 
patient assessments and the number of days on which patients are required to attend 
clinic for evaluation.  This change was made in response to Investigators’ 
observations that the schedule of assessments as documented in Revised Protocol 
Edition 3 presented a substantial burden to both patients and site staff. 
After thorough consideration, AstraZeneca has concluded that it is appropriate to 
remove some and re-assign other Part B patient assessments associated with PK/PD, 
biomarker and safety assessments. The removal and reassignment of the former 
were based on the review of the objectives of Part B and the essential data required 
to address these objectives. The change of safety assessments was based on the
judgement that sufficient safety data has been collected during Part A and the early 
stages of Part B of the study along with associated studies in the clinical 
development programme for AZD5363.  The available data are considered to
support a reduction in assessments without compromising patient care. 
These changes are reflected in the following aspects of the protocol:
a)
Updates to the 3.1.4 Schedule of Assessments Part B (Figure 8) and Sections 
6.4 to 6.9 to reflect all changes in this amendment.
b)
Consent to provide a plasma blood sample for biomarker analysis will no 
longer be optional; instead, the consent will be mandatory and included in the 
main study consent form. This sample has also been renamed ctDNA blood 
sample to clarify the intention and use of the sample.
c)
Removal of the obligation for patients to use urine dipsticks at home during 
cycle 1 in Part B of the study to monitor for presence of glycosuria. Emerging 
data have shown that glucose levels as a result of study treatment tend to peak 
at 2 to 4 hrs after ingestion of AZD5363 and are not associated with clinical 
sequelae. Patients will be monitored for hyperglycemia whilst in the clinic in 
the 2-4 hours after dosing of the study treatment during the first cycle of study

treatment.  Monitoring will be achieved via the assessment of serum glucose 
levels.  Additional monitoring in subsequent cycles may be instigated at the 
discretion of the investigator based on findings from the glucose sampling 
conducted during the first cycle of treatment.
d)
Updates to language related to analytical procedures (PK samples) and length 
of storage (CTC sample).
e)
Reductions to the volume of blood to be drawn, given the overall reduction in 
the number of assessments.
f)
Clarification concerning the acceptable time window around clinic visits.
2.
4.2 Exclusion Criteria: Change and clarification of Exclusion Criterion 4. 
Exclusion criterion 4 has been revised to:   
Receipt of any investigational drug within 30 days or 5 half-lives, whichever is 
shorter, of the first dose of AZD5363 or matching placebo. [Note: that this criterion 
does not apply where the investigational drug was an established or marketed 
breast cancer medication administered previously as part of a clinical trial, e.g., as 
a comparator in a randomised study.]
This change has been made as patients requiring first-line chemotherapy for 
advanced or metastatic breast cancer often have rapidly progressive disease or 
disease impairing organ function and for which therapy without delay is warranted.  
This is at odds with the previously mandated 30 day washout period for the prior 
therapy and this stipulation has been removed.  The 5 half-life washout has been 
retained to ensure patient safety in relation to potential drug interactions and to 
reduce the risk of confounding interpretation of safety and efficacy data collected in 
Part B of the study.  Where the safety and efficacy profile of an established breast 
cancer therapy is well established and the drug has a long half-life (e.g. fulvestrant) 
the 5 half-life stipulation is also removed to reflect real-world clinical practice and 
patient need.
3.
4.2 Exclusion Criteria: Removal of Exclusion Criterion 11. 
This criterion has been removed as it applied to patients with primary tumour types 
other than breast cancer (which was in error as only patients with breast cancer may 
be entered into the study) and incorrectly differentiated between early disease and 
advanced or metastatic disease.  The target population will commonly include 
women recurring with aggressive disease during or after adjuvant therapy for early 
disease.  This criterion is also subsumed within the revised exclusion criterion 4 
above and therefore redundant.

5.2.1.1 Determination of PIK3CA mutation status and 5.2.2 Procedures for 
allocation and randomisation: New text added to these sections.
5.2.1.1: Alternatively, based on data from the interim analysis(es), it may be 
decided to permit unselected accrual to continue with the result that the number of 
patients in the two strata will be imbalanced (see section 5.2.2).  In this instance, 
prospective screening will not be required however it will remain necessary to 
determine mutation status for all patients to enable sub-group analyses.
5.2.2: When one stratum is complete (i.e. the minimum of 50 patients corrected for 
any post-screening revised mutation status have been randomised to a stratum), 
based on results from one or more of the interim analyses or results of other studies 
of AZD5363 or agents that act on the PIK3CA pathway, AstraZeneca may elect to 
permit accrual to the completed stratum to continue or re-open.  This may result in 
imbalanced accrual between the two strata as a result of competitive accrual.  The 
total sample size of approximately 100 patients will not be affected.
This text has been added to the protocol as the field of research relating to the 
PIK3CA pathway is rapidly evolving and it is anticipated that, during the 
recruitment period of this study, data may emerge to indicate that exploring the 
hypothesis of enhanced sensitivity to AZD5363 arising from PIK3CA mutation is 
no longer a valid exercise.  If this becomes the case, forcing the enrichment of the 
study population with patients whose tumour bears the mutation may no longer be 
necessary. 
Other protocol changes in this amendment:
1.
Section 1.1.3 Clinical Information: Data presented were no longer the most up to 
date information. The reader is now referred to the Investigator’s Brochure which 
details the emerging data thus far. 
2.
Section 1.4.4 and 1.4.5 Patient risks: Text has been included regarding the risk of 
hypersensitivity reactions due to AZD5363. This change has been made as a result 
of emerging information as documented in Investigator’s Brochure Edition 6.
3.
Section 2.2. Part A and B Secondary Objectives: Addition of the secondary 
objective to assess the toxicity burden associated with diarrhoea. This change has 
been made to reflect the intention and use of the current data collection. This data 
collection is also further documented in section 6.4.3.
4.
Section 2.3 Exploratory Objectives: Clarification that the CTC assessment may 
also include characterisation of these samples. 
5.
Section 3.1.1 Asian Patient evaluation: Change of Japanese population to ‘Asian’ 
to allow sub-analyses and evaluation of emerging data from this population as 
centres in other Asian countries may be included in the study.

4.1 Inclusion Criteria: Part B Criterion 1. Patients with histological or cytologic 
diagnosis of ER+ve and HER2-ve breast cancer with evidence of relapsed advanced 
or metastatic disease.  Lesions should not be amenable to surgery or radiation of 
curative intent and must be considered unlikely to be rendered eligible for surgery 
by treatment with paclitaxel in this study. Clarification and simplification of this 
criterion.
7.
4.2 Exclusion Criteria: Removal of text within Exclusion Criterion 20.  Aspartate 
aminotransferase (AST) >2.5 times ULN if no demonstrable liver metastases or >5 
times ULN in the presence of liver metastases.  Elevated Alkaline phosphatase 
(ALP) is not exclusionary if due to the presence of bone metastasis and liver 
function is otherwise considered adequate in the investigator’s judgement.
This latter part of the criterion has been removed as this current wording is 
confusing and does not describe an exclusion criterion. 
8.
5.1 Restrictions during the study: Restriction 4 is no longer applicable to Part B 
of the study and is therefore amended accordingly.
9.
5.2 Patient enrolment process: Clarification that for Part B a separate patient 
allocation process document is not available, sufficient detail is given within section 
5.2. Correction to the description of the allocation of randomisation identification 
codes.
10.
5.5 Treatments. Table 1: Dosage form and strength of the investigational product 
updated to reflect Administrative Change Number 1, dated 8th December 2014.
11.
5.5.3 Dose and Treatment Regimens: Removal of text relating to re-dosing study 
drug if vomiting occurs after ingestion. This deletion has been made to reduce the 
possibility of overdose.
12.
5.5.3 Dose and Treatment Regimens and 3.1.2 Treatment Schedules:
Clarification to the text relating to the dosing schedule of AZD5363 study treatment 
once paclitaxel has been permanently discontinued.
13.
5.5.4 Dose modifications: Clarification to the text regarding the suspension of 
study treatment before permanent discontinuation. Appendix H has also been 
updated respectively.
14.
5.5.4 Dose modifications: Permissible dose modifications during Part B have been 
updated to reflect the available formulation strengths of the new tablet formulation 
of the investigational product.
15.
Update to the statistical section of the protocol to ensure consistency with all the 
changes in this protocol amendment.

change meaning).
17.
Other minor updates relating to study personnel, contact details and timelines.
18.
Changes to the number of participating centres and countries.
19.
Update to Appendix B to provide further information on Adverse Event reporting.
It is the judgement of the AstraZeneca Project Team that none of the protocol changes detailed 
in this document present any additional risk or hazard to the welfare or safety of participating 
patients. The changes made to this protocol do not affect the overall risk-benefit profile to the 
patient.

Early Closure of the Database.
In the event of an early closure of the database, patients are permitted to continue to receive 
study treatment if, in the opinion of the investigator, they are continuing to receive benefit 
from study treatment. For patients who do continue to receive treatment, investigators will 
continue to follow them for safety assessments as per the study plan (Figure 8) and in 
accordance with Section 6.4.3 Recording of Adverse Events. All SAEs must continue to be 
reported to AZ Patient Safety within the usual timelines until 28 days after study treatment is 
discontinued. All non-safety assessments will stop once the decision to close the clinical 
database has been communicated.
Any patients who are still receiving study medication, will be switched from IVRS/IWRS 
supply to a manual supply and the IVRS/IWRS will be closed, in line with the database 
closure.
Patients will not be considered formally withdrawn from the study until they stop taking study 
medication.

Revised text:
Hyperglycemia toxicity guidelines
These are general recommendations therefore due consideration should be given to baseline 
values and fasting condition (and time since food if applicable) when interpreting glucose 
results. In diabetic patients, it may be beneficial to rule out concomitant aetiologies that could 
be associated with hyperglycaemia (e.g. infections, dehydration, vascular events, 
glucocorticoids). Patients should be made aware of symptoms of hyperglycaemia (eg, 
polydipsia and polyuria). Dose modification guidelines for capivasertib-related hyperglycemia 
are shown below. In addition, for all grades, patients may receive education on lifestyle 
changes (eg, a diabetic diet) and consider beginning home glucose monitoring (eg, fasting 
self-blood glucose monitoring [SBGM] once-daily) at the discretion of the investigator. If 
glucose home monitoring is instituted, the capivasertib/placebo treatment decision should be 
based on the morning fasting glucose value obtained prior to the dose of capivasertib/placebo. 
It is recommended that approaches to the management of capivasertib-induced 
hyperglycaemia include advice from a diabetologist where appropriate (eg, diabetic patients). 
Metformin is currently the preferred oral antidiabetic recommended for the management of 
hyperglycaemia occurring in patients participating in studies of capivasertib. If a second agent 
is required, consideration should be given to the intermittent schedule of capivasertib and the 
pattern of glucose changes (eg. sulphonylureas should be avoided due to their risk of 
hypoglycaemia secondary to their mechanism of action).
Table 1 provides guidance on the management of events of hyperglycemia.

Appropriate clinical management of hyperglycemia
per local guidelines. Consider consult with the

Consider permanent cessation of capivasertib/placebo
NCI CTCAE v4, National Cancer Institute Common Terminology Criteria for Adverse Events
Use of Metformin and other hypoglycemics
Metformin is currently the preferred oral antidiabetic recommended for the management of
hyperglycaemia occurring in patients participating in studies of capivasertib. Investigators
should exercise caution in the dosing and management of patients receiving the
metformin/capivasertib combination and must be vigilant for signs of renal impairment and
metformin toxicity, such as lactic acidosis and hypoglycaemia, namely: lethargy, hypotension,
poor urine output, drowsiness, irritation, tachypnoea, sweating, diarrhoea, and vomiting. If a
second agent is required, consideration should be given to the intermittent schedule of
capivasertib and the pattern of glucose changes (eg, sulphonylureas should be avoided due to 
the
risk of hypoglycemia secondary to their mechanism of action).
Due to the potential interaction of metformin and capivasertib due to inhibition of OCT2, 
when
taking both capivasertib and metformin concurrently, patients should attend the clinic for
monitoring of serum creatinine at least once per week for the first 3 weeks after initiation of
metformin, then every 3 weeks thereafter.
Metformin should only be given on the days when capivasertib is also administered (the half-
life
of capivasertib is approximately 7-15 hours), and should be withdrawn when treatment with
capivasertib is withdrawn, unless otherwise clinically indicated.
Consider withholding of metformin on the days patients are due to have imaging with contrast
(in order to reduce the already low risk of lactic acidosis) per local guidelines.
