capturing safety information. Following the FPV, patients may continue to receive 
treatment with AZD1775 ± chemotherapy as deemed appropriate by the Investigator 
(see Table 2, footnote ‘bb’, Table 3, footnote ‘cc’, and Section 4.4). The end-of-study 
treatment visit is not required for patients continuing treatment after the FPV.
!
Amended Section 5.6 to add clarification about optional tumour biopsies.
!
Clarified that blood samples and optional tumour biopsies for exploratory biomarker 
research will be collected at treatment discontinuation due to disease progression for 
subjects that continue taking AZD1775 ± chemotherapy after the FPV (see Section 
5.6).
!
Clarified how SAEs will be reported after the FPV (see Section 6.4.1 and Section 6.5).
!
Clarified that after the FPV pregnancies will be monitored while patients are on 
treatment and for 30 days after their final dose of AZD1775 ±chemotherapy (Section 
6.7).

Study design
The aim of this study is to evaluate the safety and tolerability of AZD1775 when combined 
with either gemcitabine, paclitaxel, carboplatin, or PLD in patients with platinum resistant 
ovarian cancer. The research hypothesis for the AZD1775 drug development programme is 
that administration of AZD1775 combined with chemotherapy in women with platinum-
resistant ovarian, fallopian tube, or primary peritoneal carcinoma experience improved 
progression-free survival compared to women receiving chemotherapy alone.  This study is 
being conducted to understand the dose level, dosing schedule, safety, and tolerability of 
AZD1775 combined with chemotherapy agents such that they can be subsequently studied for 
improvement in efficacy.
This is an open-label, four-arm lead-in safety and efficacy study in which AZD1775 will be 
combined in four separate treatment arms as follows:  AZD1775 plus gemcitabine (Arm A); 
AZD1775 plus weekly paclitaxel (Arm B); AZD1775 plus carboplatin (Arm C); and 
PPD

AZD1775 plus PLD (Arm D [See Figure 1]).  A subset of patients will be evaluated for the 
safety assessment of each treatment arm (see Section 7.2.3.1). 
The AZD1775 plus paclitaxel arm (Arm B) will enrol approximately 30 additional patients at 
selected sites as part of a further efficacy evaluation based on emerging data that suggests 
clinical activity.
The AZD1775 plus carboplatin arm (Arm C) will enrol approximately 23 patients overall at 
selected sites as part of a further efficacy evaluation based on emerging data that suggests 
clinical activity.
To further optimise the dosing schedule of AZD1775 in Arm C, a safety expansion arm 
(referred to as Arm C2) of approximately 12 additional patients will be enrolled at selected 
sites to receive carboplatin AUC 5 IV on Day 1 of a 21 day cycle in combination with 
AZD1775 BID for 2.5 days per dosing week (QW), on Weeks 1 (D1-3), 2 (D8-10) and 3 
(D15-17), or on Weeks 1 (D1-3) and 2 (D8-10) (2 weeks on followed by 1 week off).  These 
additional weeks of AZD1775 dosing are meant to explore emerging pre-clinical and clinical 
data that suggest that prolonged AZD1775 exposure may increase the clinical activity.  
Initially, 6 patients will be enrolled in a 3-weekly AZD1775 dosing cycle; if 1 patient or less 
experiences a DLT during Cycle 1, then an additional 6 patients will be enrolled for a total of 
12 patients.  However, if 2 or more of the first 6 patients experience a DLT then the AZD1775 
dosing may be modified to 2 weeks on followed by 1 week off.  All decisions which include 
but are not limited to cohort dosing, dose escalation or de-escalation will be reviewed by the 
Safety Review Team (SRT).
Modified PK assessments will be obtained to harmonise and accommodate the investigation 
of alternative dose levels and/or schedules.

Exploratory Objectives:
Outcome Measures:
To identify genetic alterations in breast cancer 
genes 1 and 2 (BRCA1 and BRCA2) and other 
relevant genes, including TP53, from analysis of 
archived or fresh tumour tissue collected at 
baseline, and to determine if the presence of a 
genetic alteration is predictive of clinical outcomes. 
Molecular analysis of tumour tissue samples will be 
reviewed and correlated with clinical data.
To analyse changes in plasma circulating free 
tumour DNA (cfDNA) over time, from baseline, to 
restaging, and at disease progression.  (This 
exploratory analysis will be reported separately 
from the Clinical Study Report [CSR].) 
Blood samples will be collected to analyse cfDNA 
concentrations and molecular alterations.
To obtain preliminary estimates of the overall 
survival (OS) and progression-free survival (PFS) 
of AZD1775 in combination with gemcitabine, 
paclitaxel, carboplatin, or PLD.
OS, defined as the time from first dose to death from any 
cause, and progression-free survival (PFS), defined as the 
time from first dose to the first documentation of disease 
progression (according to RECIST v1.1 criteria) as 
determined by the Investigator or death from any cause, 
whichever comes first.
To collect and store deoxyribonucleic acid (DNA) 
for future research into genes/genetic variations that 
may influence PK or response to AZD1775 (i.e., 
absorption, distribution, metabolism, excretion, 
safety and efficacy) and/or susceptibility to the 
development of cancers.
Correlation of genetic polymorphisms with variation in 
PK, safety or response observed in subjects treated with 
AZD1775.
Data generated may be reported separately and may also 
form part of a pooled analysis with other AZD1775 
studies.
Target subject population
Target subject population consists of females aged 18 years or older with platinum-resistant, 
high-grade serous (HGS) epithelial ovarian, fallopian tube, or primary peritoneal cancer who 
progressed within 6 months of completing (but without progression during) at least 4 cycles of 
a first-line platinum-containing regimen for Stage III/IV disease, and had no more than 2-4
prior treatment regimens for Stage III/IV disease (investigational, chemotherapy, hormonal, 
biologic, or targeted therapy).  
Duration of treatment
Patients will be allowed to continue on therapy as long as they have no limiting toxicity or 
disease progression, have not withdrawn from the study, and are considered by the 
Investigator to still be receiving clinical benefit.  
Investigational product, dosage and mode of administration
AZD1775 is available as dry-filled capsules containing 25 or 100 mg of drug substance
AZD1775 will be provided by AstraZeneca.  Additional information about the investigational 
product (IP) may be found in the Investigator’s Brochure (IB).

Commercially available gemcitabine 800 mg/m2 IV will be infused over approximately 
30 minutes or according to institutional standards.  Refer to the gemcitabine package insert for 
additional information.
Commercially available paclitaxel will be administered as a 1-hour IV infusion (± 10 
minutes) at a dose of 80 mg/m2 according to institutional standards.  Patients should be pre-
medicated with corticosteroids, diphenhydramine and/or H2 antagonists according to 
institutional standards (see Section 7.7).  Refer to the paclitaxel package insert for additional 
information.
Carboplatin, at a dose calculated to produce an area under the curve (AUC) of 5 mg/mL min, 
will be administered by IV infusion according to institutional standards.  The carboplatin dose 
will be calculated using the Calvert Formula based on the patient’s glomerular filtration rate 
(GFR) which is estimated by using the creatinine clearance (CrCl).  Refer to the carboplatin 
package insert for additional information.
Commercially available pegylated liposomal doxorubicin (PLD) (40 mg/m2) will be 
administered by IV infusion on Day 1 of each 28-day Cycle.  PLD should be administered at 
an initial rate of 1 mg/min to minimize the risk of infusion reactions.  If no infusion related 
reactions occur, the rate of infusion can be increased to complete administration over 1 hour.  
A bolus injection or undiluted solution should not be administered.  PLD should not be mixed 
with any other drug. Refer to the package insert for additional information.
Statistical methods
Sample size calculations for Arm C of the study are based upon testing a primary endpoint of 
ORR according to RECIST v1.1. In order to test the null hypothesis of an ORR of 10% versus 
an alternative hypothesis with an ORR of 30%, 23 patients are required in order to have 85% 
power to test the null hypothesis using a one-sided exact binomial test at the 0.10 significance 
level.  The null hypothesis will be rejected if at least 5 responses are observed from 23 
patients.
The Part C2 expansion will enrol approximately 12 patients to assess a weekly AZD1775 
dosing regimen in combination with carboplatin in a 3 week cycle. Initially, 6 patients will be 
enrolled in a 3-weekly AZD1775 dosing cycle; if 1 patient or less experiences a DLT during 
Cycle 1, then an additional 6 patients will be enrolled for a total of 12 patients.  However, if 2 
or more of the first 6 patients experience a DLT then the AZD1775 dosing schedule will be 
shortened to 2 weeks on and 1 week off.   
The AZD1775 plus paclitaxel arm (Arm B) will enrol approximately 30 additional patients.  
Historical response rates using weekly paclitaxel in platinum-resistant and refractory ovarian 
cancer are in the region of 20% to 40% (Pignata et al 2015, Lortholary et al 2011, McNeish et

al 2014).  The following examples give an indication of the level of precision that will be 
achieved in the paclitaxel treated patients.
If the observed response rate is 30% (9/30), the 2-sided 80% confidence interval (CI) will be 
(18%, 43%).  If the observed response rate is 50% (15/30), the 2-sided 80% CI will be (36%, 
63%).  For decision making, ORR will be considered in addition to the observed safety and 
tolerability data and the other efficacy endpoints.

INTRODUCTION
Ovarian cancer accounts for 5% of cancer-related deaths among women in the United States 
according to the American Cancer Society.  Diagnosis of 21,980 new cases and 14,270 deaths 
were estimated in 2014 (SEER Research Data).  Although the death rate for ovarian cancer 
has been stable for the last 10 years it remains the cause of more cancer deaths of the female 
reproductive system than any other.  Fallopian tube cancer and primary peritoneal cancer are 
grouped with ovarian cancer because of their similar prognostic features.  Though less 
frequently diagnosed, these two female-reproductive cancers are known to respond to the 
same types of treatment and have similar histologic features as ovarian cancer (Bloss et al 
1993; Schneider et al 2000).  
Systemic chemotherapy with a platinum-based regimen (carboplatin or cisplatin with/without 
paclitaxel) following surgical debulking, has markedly improved the long-term survival of 
patients with advanced stage ovarian cancer.  However, patients who experience disease 
recurrence within 6 months of completing treatment (defined as platinum-resistant) have a 
poorer prognosis than platinum-sensitive patients and require subsequent treatment options in 
order to extend survival and preserve quality of life.  Platinum-resistant patients may benefit 
from retreatment with platinum-based therapy administered in a dose-dense fashion (Pignata 
et al 2015, Pinato et al 2013, Kavanagh et al 1995, and Bozas et al. 2007).  It may be possible 
to overcome platinum resistance by combining platinum with other compounds.  Carboplatin 
is approved by the Food and Drug Administration (FDA) for patients previously treated with 
cisplatin.  The Gynecologic Oncology Group (GOG) conducted a series of studies in patients 
with platinum-resistant disease (Naumann and Coleman 2011).  In one GOG study, a response 
rate (RR) of 21% was observed in 47 platinum- and paclitaxel-resistant ovarian cancer 
patients receiving weekly paclitaxel (80 mg/m2/week) until disease progression.  Previous 
treatment for this group of patients included standard paclitaxel once every three weeks 
(Markman et al 2006).  Platinum-resistant ovarian malignancies are frequently treated with 
single agents such as topotecan, paclitaxel, oral etoposide or pegylated liposomal doxorubicin 
(PLD) with RRs ranging between 5% and 15%.  Gemcitabine demonstrated activity in 8/51 
patients with platinum and taxane refractory ovarian cancer.  Four patients experienced 
significant cancer antigen-125 (CA-125) blood level declines (≥75%) and 4 patients achieved 
partial remissions of measureable disease.  Three week on/1 week off cycles of single agent 
gemcitabine were administered.  Ten patients received the initial starting dose of gemcitabine 
1250 mg/m2, 35 patients were initiated at a reduced dose of 1000 mg/m2 and 6 patients were 
started at 800 mg/m2 because of toxicity (Markman et al 2002).  The median duration of 
response (DoR) was 4 months.  Physician decision as to which agent to administer is usually 
based upon toxicity, tumour response and quality of life (Pignata et al 2015, Pinato et al 
2013).

Gemcitabine is recognized for its ability to initiate cell death, and has been FDA approved for 
relapsed ovarian cancer when combined with carboplatin (refer to package insert).  Two Phase 
II trials administering single-agent gemcitabine weekly for 3 weeks, followed by 1-week rest 
(1250 mg/m2 – 1000 mg/m2) to platinum/ paclitaxel-refractory or -resistant ovarian patients 
demonstrated RRs of 16% and 17%, respectively.  These RRs were consistent with other 
Phase 2 study responses seen in platinum-resistant patients (Markman et al 2002 , D’Agostino 
et al 2003).  
A recent report from a Phase II clinical trial indicated that patients receiving AZD1775 plus 
paclitaxel and carboplatin combination had greater progression-free survival (PFS) compared 
to patients receiving only paclitaxel and carboplatin (Oza et al 2015).  
Another study report indicated that, AZD1775 in combination with carboplatin is well 
tolerated and shows promising anti-tumour activity in patients with p53 mutated ovarian 
cancer who are refractory or resistant to standard first line therapy (Leijen et al 2015). 
Anti-tumour activity of doxorubicin against epithelial ovarian cancer has been subsequently 
proven in clinical trials (A’Hern and Gore 1995; Ozols et al 1980).  Despite its potent 
antineoplastic activity, clinical use of doxorubicin has been limited by its associated side 
effects, in particular haematological toxicity and irreversible cardiac damage.  
Recently there has been increasing attention on PLD (Gabizon 2001), which is a formulation 
of liposomal doxorubicin that is coated in polyethylene glycol (PEG).  The PEG coating 
creates a hydrophilic barrier that protects the liposomes from detection by the
reticuloendothelial system and increases the time that the active drug remains in circulation, 
which reduces the rate at which the active drug is broken down (Gabizon 2001) and makes it 
less toxic to heart muscle.  The size of the liposomes prevents PLD from entering tissues with 
tight capillary junctions, such as the heart and gastrointestinal tract; therefore it causes less 
toxicity compared with non-modified doxorubicin, while leading to increased concentrations 
within the tumour (Waterhouse et al 2001).  In 1999 it was first approved for platinum-
refractory ovarian cancer and then received full approval for platinum-sensitive recurrent 
disease in 2005.  The main toxicities associated with PLD are nausea, palmar-plantar 
erythema or hand-foot syndrome (HFS-redness and soreness of palms of hands and soles of 
feet), stomatitis and myelosuppression (Janssen-Cilag 2011).  
Pegylated liposomal doxorubicin (PLD, e.g. Doxil® and Caelyx®) class of agents are 
approved for treating patients with ovarian cancer for whom the disease has progressed or 
recurred after treatment with platinum-based chemotherapy.  In this study, the safety of PLD 
in combination with AZD1775 will be tested in some patients.

1.1
Background and rationale for conducting this study
1.1.1
The p53 signalling pathway
It is important to understand the molecular signature of tumours in order to improve 
therapeutic approaches and better manage refractory and recurrent ovarian cancer.  One of the 
most important molecular aberrations in oncogenesis is related to protein 53 (p53) a tumour 
suppressor encoded by the TP53 gene.  In normal cells, wild-type p53 plays a pivotal role in 
DNA damage repair and cell cycle arrest as well as helping to trigger apoptosis in response to 
genotoxic stress (Vogelstein et al 2000).  P53 deficiency leads to diminished DNA-repair 
capability; and germline TP53 mutations are associated with early-onset cancers such as Li-
Fraumeni and Li-Fraumeni-like syndromes (Hainaut and Hollstein 2000).  Somatic TP53
mutations are common in many forms of human cancer, as well.  Aberrant p53 function and/or 
p53 deficiency is particularly important in ovarian cancer, where the overwhelming majority 
of patients demonstrate mutations in TP53 (Vang et al 2009; Kurman and Shih 2010; 
TCGARN 2011).  These mutations are heterogeneous, presenting a very complex scenario for 
an effective drug development strategy; and it is becoming increasingly apparent that tumour-
associated mutations in the p53 signalling pathway can induce biological responses beyond 
that of simple loss of function.  Mutant p53 proteins may acquire oncogenic properties that 
promote invasion, metastasis, proliferation, and cell survival.
Since p53 is a key regulator of the G1 cell-cycle check point, p53-deficient cells 
predominantly depend on the S or G2 checkpoint for the repair of damaged cells.  Therefore, 
blocking the G2-checkpoint may selectively sensitize p53-deficient cells to DNA-damaging 
anticancer therapeutics while sparing normal tissue from toxicity.  WEE1 is a protein tyrosine 
kinase that selectively phosphorylates the Tyr15 residue on cyclin-dependent kinase 1 
(CDK1), inhibiting the transition from G2 into mitosis, preventing cells with damaged DNA 
from proliferating, so DNA repair can occur (Parker and Piwnica-Worms 1992; Igarashi et al 
1991; Watanabe et al 1995; McGowan and Russell 1993).  
Evaluation of tumour-associated mutations in the tumour suppressor TP53 has indicated that 
while most mutations abrogate p53 protein function, a small fraction of these mutations are 
not predicted to abrogate it’s function.  Therefore, a list of TP53 mutations has been generated 
that are known or predicted to have a deleterious impact on p53 function.  This list represents 
approximately 87% of known TP53 mutations in ovarian cancer, and will be used to 
determine retrospectively the TP53 mutation status of the tumour tissue being collected for 
this clinical study.

AZD1775
AZD1775 is a highly selective, adenosine-triphosphate (ATP) competitive, small-molecule 
inhibitor of the WEE1 kinase that sensitises tumour cells to cytotoxic agents and is being 
developed for the treatment of advanced solid tumours and p53 pathway deficient

malignancies.  Inhibition of the DNA damage checkpoint kinase WEE1 potentiates genotoxic 
chemotherapies by abrogating cell-cycle arrest and eliminating the opportunity for proper 
DNA repair to occur.  From a therapeutic standpoint, inhibition of checkpoint kinases that 
mediate cell-cycle arrest may force tumour cells to continue cell division before chemically 
induced DNA damage is repaired, eventually causing apoptosis or mitotic catastrophe 
(Medema and Macurek 2012).  
The primary objective of the clinical development of AZD1775 is to test it as a 
chemosensitising drug in combination with a cytotoxic agent (or combination of agents) for 
treatment of advanced solid tumours.  In vitro experiments demonstrate that AZD1775 has 
synergistic cytotoxic effects when administered in combination with various DNA damaging 
agents that have divergent mechanisms of action.  In studies with matched ovarian cell lines 
(p53 WT and shRNA p53 knockdown), AZD1775 enhanced cell death induction by 
gemcitabine in p53-deficient but not in p53 positive control cells.  AZD1775 also 
demonstrates synergistic effects on cell death induction when used in combination with 
cisplatin and carboplatin in a p53-dependent manner.  Cervical cancer cells with HPV induced 
inactivation of p53 demonstrated chemosensitisation to cisplatin and topotecan by AZD1775. 
The ability of AZD1775 to affect tumour growth as monotherapy or to enhance the anti-
tumour effects of gemcitabine, carboplatin, cisplatin, capecitabine, 5-fluorouracil, and gamma 
irradiation was evaluated in immunocompromised host animals bearing human xenograft 
tumours.
The anti-tumour effect of AZD1775 dosed as monotherapy was investigated in the A427 non-
small-cell lung cancer (NSCLC) nude mouse xenograft model.  Daily treatment with 
AZD1775 led to 51% tumour regression (n=10) and mean body weight loss did not exceed 5% 
over the course of the study.  AZD1775 single agent treatment also led to tumour growth 
inhibition in additional xenograft models: 92% TGI (Day 28) in SKMES1 model of NSCLC, 
13% regression (Day 11) in LoVo colorectal cancer model and 64% TGI (Day 19) in NCI-
H2122 NSCLC.
The anti-tumour effect of AZD1775 in combination with gemcitabine was investigated in the 
WiDr (human colorectal adenocarcinoma) nude rat xenograft model.  Several schedules of 
gemcitabine + AZD1775 were explored.  A 10 mg/kg dose of AZD1775 significantly 
enhanced the anti-tumour effect of gemcitabine in WiDr tumours with % treated/control 
(T/C) = -2%.
The anti-tumour effect of AZD1775 in combination with carboplatin was investigated in the 
HeLa-luc (human cervical adenocarcinoma) nude rat xenograft model.  AZD1775 dose-
dependently enhanced the anti-tumour effect of carboplatin tumours with %T/C = 85, 39 and 
28% at doses of 10, 20 and 30 mg/kg, respectively.

The anti-tumour effect of AZD1775 in combination with cisplatin was also investigated in the 
HeLa-luc model.  These experiments showed dose-dependently enhanced the anti-tumour 
effect of cisplatin with %T/C = -5 and -16% at doses of 10 and 20 mg/kg respectively, 
compared to carboplatin (or cisplatin) alone (X% T/C).
AZD1775 enhanced the anti-tumour efficacy of 5-FU and capecitabine when used in 
combination with these agents, as well; and experiments with nude mouse xenograft models 
of A549 (p53 wild type) and Calu-6 (p53 null) NSCLC cell lines showed enhanced anti-
tumour growth effect of radiotherapy preferentially in p53 mutant xenograft tumours.  Please 
refer to the AZD1775 Investigator Brochure (IB) for more detailed information regarding 
these experiments and findings.
PLD is an anthracycline topoisomerase II inhibitor approved for treatment of patients with 
ovarian cancer who have failed on platinum-based chemotherapy.  AZD1775 has been 
reported to potentiate cytotoxic effects of doxorubicin in vitro (Hirai et al 2010).  This report 
supports the rationale of assessing the safety of doxorubicin in combination with AZD1775 as 
a potential therapeutic approach.
1.1.2.1
AZD1775 clinical experience
AZD1775 has been and is being evaluated in several clinical studies, including both phase I 
and phase II studies in a variety of combinations and tumour settings (AZD1775 (MK-1775) 
IB).  These include:
!
PN001 (NCT 00648648) (except for Part 3):  a first-time-in-patients (FTIP), Phase I, 
dose-escalation study evaluating AZD1775 both as monotherapy and combination therapy 
with gemcitabine, cisplatin, or carboplatin in adult patients with advanced solid tumours
!
PN005 (NCT 01047007):  a Phase I, dose-escalation study evaluating AZD1775 as 
monotherapy (Part 1), combination therapy with 5-FU (Part 2), and combination therapy 
with 5-FU plus cisplatin (Part 3) in adult Japanese patients with advanced solid tumours 
was terminated early due to portfolio prioritization in oncology at Merck after 3 patients 
had been enrolled in Part 1 and 8 patients had been enrolled in Part 2.  Part 3 was not 
initiated.
!
PN008 (NCT 01076400):  a Phase I/IIa, dose-escalation study evaluating AZD1775 in 
combination with topotecan plus cisplatin in adult patients with cervical cancer was 
terminated early due to portfolio prioritization in oncology at Merck after 7 patients had 
been enrolled in the dose-escalation part of the study.  Phase IIa was not initiated.
In Study PN001 (NCT 00648648), of 176 evaluable patients who received AZD1775 (either 
single or multiple doses) as monotherapy or in combination with gemcitabine, cisplatin, or 
carboplatin, a partial response (PR) (confirmed and unconfirmed) was observed in 17 (9.7%) 
patients, and stable disease (SD) was observed in 94 (53.4%) patients (AZD1775 (MK-1775) 
IB).  Nine patients received AZD1775 monotherapy.  Single ascending doses of AZD1775 up 
to 1300 mg were well tolerated; the maximum tolerated dose (MTD) was not evaluated.

In Study PN005 (NCT 01047007), patients in Part 1 received single-cycle twice-daily (BID) 
dosing of AZD1775 for 5 days as monotherapy.  A cohort of 3 patients was enrolled at the 
starting dose level of AZD1775 65 mg BID and no serious adverse events (SAEs) were 
experienced.  
An ongoing study (NCT 01748825) sponsored by the National Cancer Institute (NCI) Cancer 
Therapy Evaluation Program, in collaboration with AstraZeneca, is investigating AZD1775 
monotherapy.  The MTD for monotherapy treatment in patients with advanced refractory solid 
tumours was found to be 225 mg BID x 5 on Weeks 1 and 2 of a 3-week schedule.  Paired 
biopsies were obtained from 5 patients on this dose and schedule.  The biopsies showed that a 
decrease in pCDC2 was observed in the post-treatment biopsy in 3 of the biopsy pairs with an 
average of 80% reduction.  The same biopsies were analysed for increases in γH2AX, an 
indicator of DNA damage.  Three of the 5 biopsy pairs showed a post-treatment increase in 
γH2AX, with an average of 404% induction observed in these 4 biopsy pairs.  This study is 
also evaluating a once daily (QD) schedule for monotherapy starting at a 200 mg dose.  
Twenty-five patients have been enrolled for the BID schedule and 3 for the QD schedule.
As of 11 November 2016, a total of approximately 551 patients have been exposed to 
AZD1775 in AstraZeneca-sponsored or Merck-sponsored clinical studies.  In addition, 350
patients have also received AZD1775 as part of AstraZeneca’s externally-sponsored scientific 
research.  These patients have received single doses per cycle as high as 1300 mg of 
AZD1775 as monotherapy, 325 mg of AZD1775 as a single-dose in combination with 
chemotherapy, and 325 mg BID in a multiple-dose regimen in combination with 
chemotherapy.  Please refer to the current version of the AZD1775 IB.
The most common adverse events (AEs) observed in studies of AZD1775 combined with 
chemotherapy include blood and lymphatic disorders, (i.e., thrombocytopenia, neutropenia, 
leukopenia, anaemia, febrile neutropenia), gastrointestinal disorders (i.e., diarrhoea, vomiting, 
nausea, abdominal pain, and constipation), and blood investigations (haematology and serum 
chemistries).  Other reported safety concerns include electrocardiogram (ECG) QT 
prolongation, fatigue, influenza like illness, malaise, mucosal inflammation, myalgia, 
palpitations, pruritus, pyrexia, rash, rash maculopapular, skin lesion, stomatitis, tachycardia, 
loss of weight.
The single-dose maximum tolerated dose (MTD) of AZD1775 was 200 mg in combination 
with gemcitabine and/or cisplatin.  Dose-limiting toxicities (DLTs) tended to be 
haematological in nature in the gemcitabine group and constitutional in the cisplatin group.  
The single-dose MTD for the combination with carboplatin was 325 mg of AZD1775.  DLTs 
in this group were related to serum chemistry. 
Hematologic DLTs were most commonly observed in the multiple-dose AZD1775 
combination treatment groups with gemcitabine and cisplatin.  An MTD of AZD1775 in

combination with gemcitabine was established with an interim dose of 50 mg BID on Day 1, 
25 mg BID on Day 2, and 25 mg on Day 3.  An attenuated once daily for 2 day schedule in 
combination with gemcitabine continues under investigation.  Two DLTs (grade 3 febrile 
neutropenia and grade 3 aspartate aminotransferase (AST) and alanine aminotransferase 
(ALT) increase) were observed at 200 mg once daily for 2 days with the regimen in 
combination with gemcitabine.  The dose was adjusted to 175 mg once daily for 2 days, and 
one DLT has been reported to date.  The MTD for combination with cisplatin has been 
exceeded at the 250 mg dose level, and tolerability of the MTD at 200 mg BID has been 
confirmed.  DLTs observed in the multiple-dose carboplatin combination have been both 
haematological and constitutional in nature.  The multiple-dose MTD in combination with 
carboplatin is AZD1775 225 mg BID.
The MTD for AZD1775 in combination with 5-FU was not reached due to early study 
termination.  DLTs of encephalopathy and hyponatraemia were observed in the AZD1775 
20 mg BID in combination with 1000 mg/m2 5-FU treatment group.
Triplet-based therapy was administered in the study PN004, AZD1775, carboplatin, and 
paclitaxel.  The starting dose of 225 mg AZD1775 (BID for 5 total doses) in Part 1 was 
generally well tolerated.  One patient experienced a DLT in the first six patients treated and 
the dose remained at 225 mg BID 2.5 days.  A total of 15 patients were treated, with 3 DLTs 
being reported (grade 3 and 4 febrile neutropenia and grade 4 thrombocytopenia).  The study 
expanded to Part 2 and is ongoing.  Other toxicities were generally blood and lymphatic 
system disorders and gastrointestinal.  
For the combination of AZD1775 with topotecan plus cisplatin in study PN008, toxicities 
were generally haematological and gastrointestinal in nature.  No unexpected toxicities were 
observed.  
In study PN009 and the premarket formulation substudy to PN001 (both combining 2.5-day 
BID dosing of AZD1775 with carboplatin) there were no appreciable differences in toxicity 
from the ones observed in the carboplatin arm of study PN001.  However, increased 
haematological toxicity was observed, which is considered to be a function of a drug-drug 
interaction with aprepitant (which was administered as anti-nausea medication in these 
studies).
Preliminary pharmacokinetic (PK) analyses revealed that co-administration of AZD1775 and 
aprepitant results in a ~60% increase of AZD1775 exposure.
Available preliminary efficacy data are encouraging, with confirmed PRs in patients 
participating in the two ovarian trials, as well as the phase I trial in solid tumours.  Several 
studies are ongoing (AZD1775 (MK-1775) IB).

1.1.3
Rationale for conducting this study
The purpose of this study is to find a new alternative treatment for platinum-resistant TP53-
mutated high-grade serous (HGS) ovarian cancer patients.  AZD1775 has demonstrated 
efficacy in two ongoing ovarian carcinoma studies (PN004 and PN009) combined with either 
carboplatin alone or carboplatin and paclitaxel.  
The platinum-resistant HGS ovarian patient presents unique treatment challenges.  TP53
mutations in HGS ovarian cancer occur in 80-96% of patients.  In one report, TP53 mutations 
were reported in 96% of 316 HGS ovarian cancer patients using high-throughput technology 
(TCGARN 2011).  In the current study, archival tumour samples will be required to confirm 
TP53 mutation status, in a retrospective manner.
The current study is an open-label, four-arm, lead-in safety and efficacy study of gemcitabine, 
paclitaxel, carboplatin or PLD in combination with AZD1775.   
This study is intended to provide important safety and efficacy data for administering 
AZD1775 in combination with chemotherapy (gemcitabine, carboplatin, weekly paclitaxel, or 
PLD).  
1.2
Rationale for study design, doses and control groups
The aim of this study is to evaluate the safety and tolerability of AZD1775 when combined 
with either gemcitabine, paclitaxel, carboplatin, or PLD in patients with platinum resistant 
ovarian cancer. The research hypothesis for the AZD1775 drug development programme is 
that administration of AZD1775 combined with chemotherapy in women with platinum-
resistant TP53 mutated ovarian, fallopian tube, or primary peritoneal carcinoma experience 
improved PFS compared to women receiving chemotherapy alone.  This study is being 
conducted to understand the dose level, dosing schedule, safety, and tolerability of AZD1775 
combined with chemotherapy agents such that they can be subsequently studied for 
improvement in efficacy.
This is an open-label, four-arm lead-in safety and efficacy study in which AZD1775 will be 
combined in four separate treatment arms as follows:  AZD1775 plus gemcitabine (Arm A); 
AZD1775 plus weekly paclitaxel (Arm B); AZD1775 plus carboplatin (Arm C); and 
AZD1775 plus PLD (Arm D [See Figure 1]).  A subset of patients will be evaluated for the 
safety assessment of each treatment arm (see Section 7.2.3.1).  The dose/schedules for 
AZD1775 and paired chemotherapeutic agents that will be used in the lead in safety/expansion 
are presented below:  
Arm A (AZD1775 175 mg PO daily days (D)1-2, 8-9, 15-16 + gemcitabine 1000 mg/m2 IV 
D1, 8, 15 q28D);

Arm B (AZD1775 225 mg PO BID x 5 doses D1-3, 8-10, 15-17 + paclitaxel 80 mg/m2 IV D1, 
8, 15 q28D);   
Arm C (AZD1775 225 mg PO BID x 5 doses D1-3 + carboplatin AUC 5 IV D1 q21D) 
Arm D (AZD1775 175 or 225 mg PO BID x 5 doses D1-3 + PLD 40 mg/m2 IV D1 q28D) 
The AZD1775 plus paclitaxel arm (Arm B) will enrol approximately 30 additional patients at 
selected sites as part of a further efficacy evaluation based on emerging data that suggests 
clinical activity.
The AZD1775 plus carboplatin arm (Arm C) will enrol approximately 23 patients overall at 
selected sites as part of a further efficacy evaluation based on emerging data that suggests 
clinical activity.
To further optimise the dosing schedule of AZD1775 in Arm C, a safety expansion arm 
(referred to as Arm C2) of approximately 12 additional patients will be enrolled at selected 
sites to receive carboplatin AUC 5 IV on Day 1 of a 21 day cycle in combination with 
AZD1775 BID for 2.5 days per dosing week (QW), on Weeks 1 (D1-3), 2 (D8-10) and 3 
(D15-17), or on Weeks 1 (D1-3) and 2 (D8-10) (2 weeks on followed by 1 week off).  These 
additional weeks of AZD1775 dosing are meant to explore emerging pre-clinical and clinical 
data that suggest that prolonged AZD1775 exposure may increase the clinical activity.  
Initially, 6 patients will be enrolled in a 3-weekly AZD1775 dosing cycle; if 1 patient or less 
experiences a DLT during Cycle 1, then an additional 6 patients will be enrolled for a total of 
12 patients.  However, if 2 or more of the first 6 patients experience a DLT then the AZD1775 
dosing may be modified to 2 weeks on followed by 1 week off.  All decisions which include 
but are not limited to cohort dosing, dose escalation or de-escalation will be reviewed by the 
Safety Review Team (SRT).
Modified PK assessments will be obtained to harmonize and accommodate the investigation 
of alternative dose levels and/or schedules.
1.3
Benefit/risk and ethical assessment
The investigation of AZD1775 in this patient population appears acceptable based upon the 
non-clinical profile and emerging clinical data.  The lead-in safety and efficacy phase of the 
study will be risk minimising with safety and medical monitoring, PK assessments, and Safety 
Review Team (SRT) involvement.  Overall the benefit/risk assessment supports the 
administration of AZD1775 to patients with platinum-resistant ovarian, fallopian tube, or 
primary peritoneal carcinoma.

Based on the safety data from the completed AZD1775 clinical studies and preliminary data 
from ongoing studies, adverse drug reactions to AZD1775 monotherapy include: anaemia, 
neutropenia, thrombocytopenia, QTc prolongation, gastrointestinal events such as dyspepsia, 
diarrhoea, nausea, and vomiting (with or without dehydration or serum electrolyte decreases), 
as well as decreased appetite.  In addition, the following events are also considered expected 
during treatment with AZD1775 in combination with cytotoxic chemotherapy: febrile 
neutropenia, leukopenia, stomatitis, asthenia, fatigue, mucosal inflammation, and myalgia. 
Based on information emerging during the clinical development programme of AZD1775, 
potential risks with AZD1775 monotherapy include asthenia/fatigue, febrile neutropenia, 
gastrointestinal haemorrhage, lymphopenia/lymphocyte count decreased, leukopenia/WBC 
count decreased, myalgia, stomatitis, sepsis and transaminases elevation.  Gastrointestinal 
haemorrhage and sepsis are described in further detail in the current IB.
In addition, the following events are also considered potential risks for AZD1775 in 
combination with cytotoxic chemotherapy: tachycardia and pancytopenia.
Refer to the IB for AZD1775 for information on the potential benefits and assessment of 
potential and known risks.

Exploratory objectives  
Exploratory Objectives:
Outcome Measures:
To identify genetic alterations in breast cancer 
genes 1 and 2 (BRCA1 and BRCA2) and other 
relevant genes, including TP53, from analysis of 
archived or fresh tumour tissue collected at 
baseline, and to determine if the presence of a 
genetic alteration is predictive of clinical outcomes. 
Molecular analysis of tumour tissue samples will be 
reviewed and correlated with clinical data.
To analyse changes in plasma circulating free 
tumour DNA (cfDNA) over time, from baseline, to 
restaging, and at disease progression.  (This 
exploratory analysis will be reported separately 
from the Clinical Study Report [CSR].) 
Blood samples will be collected to analyse cfDNA 
concentrations and molecular alterations.
To obtain preliminary estimates of the overall 
survival (OS) and progression-free survival (PFS) 
of AZD1775 in combination with gemcitabine, 
PLD, carboplatin or paclitaxel 
OS, defined as the time from first dose to death from any 
cause, and progression-free survival (PFS), defined as the 
time from first dose to the first documentation of disease 
progression (according to RECIST v1.1 criteria) as 
determined by the Investigator or death from any cause, 
whichever comes first
To collect and store DNA for future research into 
genes/genetic variations that may influence PK or 
response to AZD1775 (i.e., absorption, distribution, 
metabolism, excretion, safety and efficacy) and/or 
susceptibility to the development of cancers.
Correlation of genetic polymorphisms with variation in 
PK, safety or response observed in subjects treated with 
AZD1775.
Data generated may be reported separately and may also 
form part of a pooled analysis with other AZD1775 
studies.

The Investigator(s) will:
1
Obtain signed informed consent from the potential patient before any study specific 
procedures are performed.  Obtain study identifier according to the instructions provided 
in the Study Reference Manual.
2
Assign the patient a unique enrolment number/code.
3
Determine subject eligibility. See Sections 3.1 and 3.2.
If a subject withdraws from participation in the study, then his/her enrolment code cannot be 
reused.
3.3.1
Optional Pharmacogenetic (PGx) research 
For inclusion in the optional exploratory PGx research, patients must provide informed 
consent for pharmacogenetic research.
Exclusion from this pharmacogenetic research may be for any of the exclusion criteria 
specified in the main study or any of the following:
!
Previous allogenic bone marrow transplant
!
Non-leukocyte depleted whole blood transfusion within 120 days of genetic sample 
collection.
If a patient declines to participate in the optional exploratory pharmacogenetic research, there 
will be no penalty or loss of benefit to the patient.  The patient will not be excluded from other 
aspects of the study.
3.4
Procedures for handling incorrectly enrolled subjects
Subjects who fail to meet the eligibility criteria should not, under any circumstances, be 
enrolled or receive study medication.  There can be no exceptions to this rule.  Subjects who 
are enrolled, but subsequently found not to meet all the eligibility criteria must not be initiated 
on treatment, and must be withdrawn from the study.
Where a subject does not meet all the eligibility criteria but is enrolled in error, or incorrectly 
started on treatment, the Investigator should inform the Medical Monitor (MM) immediately, 
and a discussion should occur between the MM and the Investigator regarding whether to 
continue or discontinue the patient from treatment. The MM must ensure all decisions are 
appropriately documented.

TP53 testing
TP53 mutations are so prevalent in the eligible patient population that requiring proof of these 
mutations prior to enrolment is no longer necessary in the amended protocol.  Retrospective 
TP53 mutation assessments will be performed centrally from archival tumour tissue.  A full 
report that includes all of the genes present on the gene panel will subsequently be made 
available to Investigators upon request.
Refer to the Laboratory Manual for complete instructions.  
3.6
Methods to ensure blinding
The study is open-label; therefore, blinding procedures are not applicable.

Methods for unblinding
This is open-label; therefore, unblinding procedures are not applicable.
3.8
Restrictions
Please see Appendix G for information regarding concomitant medications that are prohibited 
or should be avoided while receiving AZD1775 and chemotherapy.  Additional restrictions 
include the following:
!
Women of childbearing potential (WoCBP) may be included only if acceptable 
contraception is in place for two weeks before study entry, for the duration of the study 
and for one month after the last dose of AZD1775 (see Appendix E for definitions of non-
childbearing potential and acceptable contraceptive methods).
!
WoCBP defined as: Women between menarche and menopause who have not been 
permanently or surgically sterilized and are capable of procreation.
!
WoCBP receiving paclitaxel chemotherapy may be included in the study only if 
acceptable contraception is in place for 2 weeks before study entry, for the duration of the 
study and for at least 6 months after the last dose of paclitaxel treatment.
!
All WoCBP must have a negative pregnancy test within 3 days of starting study treatment 
and confirmed prior to the start of study treatment on the first day of dosing.  WoCBP 
must have a negative pregnancy test prior to starting each new treatment cycle and at the 
end-of-treatment visit (EOT).

3.9.1
Procedures for discontinuation of a subject from investigational 
product 
At any time, subjects are free to discontinue IP or withdraw from the study (i.e., IP and 
assessments – see Section 3.10), without prejudice to further treatment.  A subject that decides 
to discontinue investigational will always be asked about the reason(s) and the presence of any 
AEs.  If possible, they will be seen and assessed by an Investigator(s).  Adverse events will be 
followed up (see section 6), and all study drugs should be returned by the subject.
If a subject is withdrawn from study, see Section 3.10.
3.10
Criteria for withdrawal 
Reasons for withdrawal from the study:
!
Withdrawal of consent
!
Death
!
Incorrectly enrolled or treated patient
!
AE
!
Patient is lost to follow-up
If a patient wishes to withdraw her consent to both treatment and study assessments, they 
should be asked if they are willing to continue with survival follow-up (which can be 
conducted by telephone).  If a patient wishes to withdraw her consent to further participation 
in the study entirely, including survival follow-up, this should be clearly documented in the 
patient medical record and in the electronic case report form (eCRF).
The status of ongoing, withdrawn (from the study) and “lost to follow-up” patients at the time 
of analysis should be obtained by the site personnel by checking the patient’s medical record 
and hospital records, contacting the patient’s general practitioner, and checking publicly 
available death registries.  In the event that the patient has actively withdrawn consent to the 
processing of their personal data, the vital status of the patient can still be obtained by site 
personnel from publicly available resources where it is possible to do so under applicable 
local laws.

3.10.1
Screen failures 
Screening failures are patients who do not fulfil the eligibility criteria for the study, and 
therefore must not be enrolled.  These patients should have the reason for study withdrawal 
recorded as ‘Incorrect Enrolment’ (i.e., patient does not meet the required inclusion/exclusion 
criteria).  This reason for study withdrawal is only valid for screen failures (not enrolled
patients).
3.10.2
Withdrawal of the informed consent
Patients are free to withdraw from the study at any time (IP and assessments), without 
prejudice to further treatment.
A patient who withdraws consent will always be asked about the reason(s) and the presence of 
any AEs.  The Investigator will follow up AEs outside of the clinical study. 
If a subject withdraws from participation in the study, then her enrolment code cannot be 
reused. Withdrawn patients will not be replaced unless they withdraw in Cycle 1 of the Part 1 
lead-in safety cohort.
3.10.3
Lost to follow-up
Patients will be considered lost to follow-up only if contact was lost and could not be re-
established by the time the study is completed, and there is insufficient information to 
determine the patient’s status at that time.  Note: Patients who refuse to continue participation 
in the study, including telephone contact, should be documented as ‘withdrawal of consent’ 
rather than ‘lost to follow-up’.  Investigators should document attempts to re-establish contact 
with missing patients throughout the study period.  If contact with a missing patient is re-
established, the patient should not be considered lost to follow-up and any evaluations should 
resume according to the protocol.  If a patient withdraws from participation in the study, then 
their patient number cannot be reused.
3.11
Discontinuation of the study
The study may be stopped if, in the judgment of AstraZeneca, trial subjects are placed at 
undue risk because of clinically significant findings that:
!
meet individual stopping criteria or are otherwise considered significant 
!
are assessed as causally related to study drug, 
!
are not considered to be consistent with continuation of the study
Regardless of the reason for termination, all data available for the subject at the time of 
discontinuation of follow-up must be recorded in the electronic case report form (eCRF). All 
reasons for discontinuation of treatment must be documented.

a
The physical examination, vital signs, medical history (capture previous treatment medications and response to each prior treatment regimen), concomitant 
medications (recorded ≤14 days prior to trial entry), ECOG PS, complete blood count (CBC) with differential and platelets, clinical chemistry, urinalysis, 
and 12-lead ECG should be done ≤7 days prior to initiation of treatment.  However, if any of these initial examinations are required at Cycle 1 Day 1 and 
are obtained within 3 days prior to the initiation of treatment they do not have to be repeated.  CA-125 should be done within 14 days prior to the initiation 
of treatment.  Scans to document evaluable disease (i.e., tumour measurement) should be performed ≤28 days prior to initiation of treatment and should be 
performed as close to the start of treatment as possible.  
b
All patients must provide a tumour sample (archival) for TP53 testing and other exploratory biomarkers by a central laboratory (see Section 5.6).    
c
Vital signs (resting heart rate, blood pressure, temperature and weight) at the Screening visit will include height.  After Screening, height will not be 
measured. Vital signs and weight will be obtained prior to chemotherapy administration according to institutional practice.  
d
Clinical chemistry will include measurements of glucose, BUN, creatinine, sodium, potassium, chloride, calcium, CO2, alkaline phosphatase (ALP), AST, 
ALT, total bilirubin, total protein, lactate dehydrogenase (LDH), phosphorus, and albumin.  
e
Coagulation performed at baseline only (PT or INR with PTT) should be done ≤7 days prior to initiation of treatment.  Repeat at the beginning of every 
cycle if patient on Coumadin.
f
QTc interval will be calculated using Fridericia's formula (as calculated per institutional standards) obtained from 3 ECGs 2-5 minutes apart at study entry 
(see Section 3.2). In addition, patients will have triplicate 12-lead ECGs performed 2-5 minutes apart at the beginning of each treatment cycle. 
g
Pregnancy tests will only be performed in women of childbearing potential (WoCBP) within 3 days of starting study treatment and confirmed prior to start 
of study treatment on the first day of dosing.  WoCBP must have a negative pregnancy test prior to starting each new treatment cycle and at the end-of-
treatment visit (see Section 3.8).
h
Patients will be restaged after every 2 cycles (every 8 weeks [±7 days]).  Patients with progressive disease (PD) or unacceptable toxicity should be 
discontinued from the study; patients with SD or response to therapy will continue treatment.
i
Computed tomography (CT) scans/magnetic resonance imaging (MRI) of the chest and abdomen and pelvis are required at baseline and every 2 cycles (8 
weeks).
j
The same method of assessment and the same technique must be used to characterize each identified and reported lesion at baseline and during subsequent 
imaging procedures. Patients continuing study treatment beyond 1 year may have the tumour imaging assessments expanded to every 3 cycles (12 weeks 
[±7 days]).
k
Patients without evidence of undue toxicity may continue treatment with study drugs until disease progression occurs as long as they are achieving clinical 
benefit and desire to continue therapy.  
l
The End of Study Treatment Visit will be performed 30 days after the last dose of study treatment or prior to the beginning of new therapy.  Reassessments 
for toxicity, disease progression, and survival will be performed 30 days from last treatment dose (see Section 7.2.7).  Tumour assessments will be repeated 
at the end of study treatment visit if they have not been performed within the past 2 cycles (3 cycles for patients on study for >1 year).
m
Post follow-up for patients without disease progression at the time of study drug discontinuation should include repeat CT scan(s) and CA-125 (if 
applicable) until disease progression has been observed.  The patient will be followed every 3 months (±1 week) from the date of the last tumour assessment 
and assessment of response, until death or until the study is terminated by the sponsor.    
n
Patients with documented disease progression will be followed every 3 months (±1 week) for survival status (e.g., date and cause of death).  Patients may be 
contacted during outpatient visits or by telephone.  All post study therapies and dates of administration will be collected.
o
CA-125 serum sample collected at baseline (within 14 days prior to first study treatment), Day 1 of each cycle, and end-of-study treatment visit (see Section 
5.2.4).

p
The 6 patients in the lead-in safety group will have limited plasma PK samples collected pre-and post AZD1775 dosing (see Table 6 and Section 5.3.1).  PK 
samples will be collected at the following time points:  Cycle 1 Day 1 - 2 samples will be collected pre AZD1775 and gemcitabine administration (this 
collection may be done the previous day).  Two samples will be collected at 30 minutes post AZD1775 morning dosing (once the gemcitabine infusion 
ends), and at 1, 2, and 4 hours.  One sample will be collected at 6 hours and at the end of the first day, ideally around 8 hours post AZD1775 dosing.  On 
Cycle 2 Day 1, samples will be collected at 2 hours and 3-4 hours after AZD1775 dosing.  On Cycle 3 Day 1, 30 minutes to1 hour and 2 hours after 
AZD1775 dosing, Cycle 3 Day 2 after AZD1775 is dosed, and Cycle 4 Day 1 before AZD1775 dosing and 2 hours after dosing occurs.  Refer to the 
Laboratory Manual.
q
Collection of cfDNA to explore the genetic tumour markers in plasma correlation with markers in tumour samples and to monitor for the emergence of 
resistance is mandatory at baseline, restaging, end-of-treatment and progression for all patients.  A baseline plasma sample will be required followed by 
subsequent single plasma samples at the time of each restaging, end-of-treatment and progression.  Plasma samples will be collected in an EDTA tube and 
processed according to the Laboratory Manual.  See Section 5.6 for more information.

a
The physical examination, vital signs, medical history, (capture previous treatment medications and response to each prior treatment regimen), concomitant 
medications (recorded ≤14 days prior to trial entry), ECOG PS, complete blood count (CBC) with differential and platelets, clinical chemistry, urinalysis, 
and 12-lead ECG should be done ≤7 days prior to initiation of treatment.  However, if any of these initial examinations are required at Cycle 1 Day 1 and 
obtained within 3 days prior to the initiation of treatment they do not have to be repeated.  CA-125 should be done within 14 days prior to initiation of 
treatment.  Scans to document evaluable disease (i.e., tumour measurement) should be performed ≤28 days prior to initiation of treatment and should be
performed as close to the start of treatment as possible. 
b
All patients must provide a tumour sample (archival) for TP53 testing and other exploratory biomarkers by a central laboratory (see Section 5.6).    
c
Vital signs (resting heart rate, blood pressure, temperature and weight) at the Screening visit will include height.  After Screening, height will not be 
measured.  Vital signs and weight will be obtained prior to chemotherapy administration according to institutional practice at screening, on Day 1 of each 
cycle visit, at the end-of-study treatment visit, and the final protocol visit (FPV).
d
Clinical chemistry will include measurements of glucose, BUN, creatinine, sodium, potassium, chloride, calcium, CO2, ALP, AST, ALT, total bilirubin, 
total protein, lactate dehydrogenase (LDH), phosphorus, and albumin.  
e
Coagulation performed at baseline only (PT or INR with PTT) should be done within ≤7 days prior to the initiation of treatment.  Repeat at the beginning of 
every cycle if patient on Coumadin.
f
QTc interval will be calculated using Fridericia's formula (as calculated per institutional standards) obtained from 3 ECGs 2-5 minutes apart at study entry 
(see Section 3.2). In addition, patients will have triplicate 12-lead ECGs performed 2-5 minutes apart at the beginning of each treatment cycle including the 
FPV.  
g
Pregnancy tests will only be performed in WoCBP within 3 days of starting study treatment and confirmed  prior to start of study treatment on the first day 
of dosing.  WoCBP must have a negative pregnancy test prior to starting each new treatment cycle and at the end-of-treatment visit (see Section 3.8), and at
the FPV.
h
Patients will be restaged after every 2 cycles (every 8 weeks [±7 days]).  Patients with PD or unacceptable toxicity should be discontinued from study
treatment; patients with SD or response to therapy will continue treatment.
i
CT scans/MRIs of the chest and abdomen and pelvis are required at baseline and every 2 cycles (8 weeks).  
j
The same method of assessment and the same technique must be used to characterize each identified and reported lesion at baseline and during subsequent 
imaging procedures.  Patients continuing study treatment beyond 1 year may have the tumour imaging assessments expanded to every 3 cycles (12 weeks 
[±7 days]).
k
Patients without evidence of undue toxicity may continue treatment with study drugs until disease progression occurs as long as they are achieving clinical 
benefit and desire to continue therapy.  
l
The End of Study Treatment Visit will be performed 30 days after the last dose of study treatment or prior to the beginning of new therapy. Reassessments 
for toxicity, disease progression, and survival will be performed 30 days from last treatment dose (see Section 7.2.7).  Tumour assessments will be repeated 
at the end of study treatment visit if they have not been performed within the past 2 cycles (3 cycles for patients on study for >1 year). The end-of-study 
treatment visit is not required for patients continuing treatment after the FPV.
m
Post follow-up for patients without disease progression at the time of study drug discontinuation should include repeat CT scan(s) and CA-125 (if 
applicable) until disease progression has been observed.  The patient will be followed every 8 weeks (±1 week) from first dose (every 12 weeks for patients 
on study >1 year) until progression, death or until the study is terminated by the sponsor.  
n
Patients with documented disease progression will be followed every 3 months (±1 week) for survival status (e.g., date and cause of death).  Patients may be 
contacted during outpatient visits or by telephone.  All post study therapies and dates of administration will be collected.
o
CA-125 serum sample collected at baseline (until 14 days prior to first study treatment), Day 1 of each cycle, at the end-of-study treatment visit, and the 
FPV (see Section 5.2.4).

p
The 6 patients in the lead-in safety group will have limited plasma PK samples collected pre-and post AZD1775 dosing (see Table 7 and Section 5.3.1).  PK 
samples will be collected at the following time points:  Cycle 1 Day 1 - 2 samples will be collected at each of the following time points:  before AZD1775 
and paclitaxel administration (this collection may be done the day before), 1 sample at 30 minutes post AZD1775 morning dosing, 2 samples (once the 
paclitaxel infusion stops) at 1, 2, 4, and 6 hours post AZD1775 dosing and at the end of the first day, ideally around 8 hours from AZD1775 dosing.  On 
Cycle 2 Day 1, samples will be collected at 2 hours and 3-4 hours after AZD1775 dosing.  On Cycle 3 Day 1, 30 minutes to1 hour and 2 hours after 
AZD1775 dosing, Cycle 3 Day 2 after AZD1775 is dosed, and Cycle 4 Day 1 before AZD1775 dosing and 2 hours after dosing occurs.  Refer to the 
Laboratory Manual.  
q
Efficacy Expansion:  Mandatory sparse AZD1775 PKs will be collected from patients pre-dose, post-dose 1 hour and post-dose 2-4 hours to be collected on 
Day 3 or Day 10 or Day 17 on Cycle 1, 3, 5 and 7 (see Table 14).  Paclitaxel ONLY PKs will be collected described in Table 7 during Cycle 1 (before 
paclitaxel administration (this collection may be done the day before), 1 samples (once the paclitaxel infusion stops) at 1, 2, 4, and 6 hours post AZD1775 
dosing and at the end of the first day, ideally around 8 hours.
r
Collection of cfDNA to explore the genetic tumour markers in plasma correlation with markers in tumour samples and to monitor for the emergence of 
resistance is mandatory at baseline, Cycle 2 Day 1, Day 1 of every odd-numbered cycle (Cycles 3, 5, etc.), end-of-treatment and progression for all patients.
Patients continuing treatment after the FPV will have a cfDNA sample collected if the patient discontinues treatment due to disease progression. Plasma 
samples will be collected in an EDTA tube and processed according to the Laboratory Manual. See Section 5.6 for more information.
s
Patients with elevated CA-125 levels that can be monitored for response will be assessed according to the GCIG CA-125 response criteria in addition to 
RECIST v1.1.  An additional sample will be collected for tumour response monitoring.  Patients can be evaluated according to CA-125 only if they have a 
pre-treatment sample that is at least twice the ULN and within 2 weeks prior to starting treatment (see Section 5.1).
t
Five doses of AZD1775 (225 mg PO BID) will be taken in approximate 12 hour intervals over 2.5 days weekly (Days 1-3, 8-10 and 15-17).  AZD1775 
should be taken approximately 2 hours before or 2 hours after food. Beyond the FPV, patients may continue to receive AZD1775 if they are deriving 
clinical benefit, in the opinion of the Investigator, and not fulfilling any of the discontinuation criteria.
u
Weekly paclitaxel 80 mg/m2 IV will be administered according to institutional standards on Days 1, 8 and 15 of each 28 day cycle. After the FPV, patients 
will continue to receive paclitaxel 80 mg/m2 IV until disease progression, or until they no longer derive clinical benefit, or until they fulfil any 
discontinuation criteria, in the opinion of the Investigator. Drug accountability information must continue to be collected in patient source documents until 
the patient discontinues the treatment.  
v
Review and document AZD1775 dosing compliance with the patient at the beginning of each new treatment cycle when study drug is dispensed.   
w
Optional tumour biopsy samples will be requested from patients that discontinue treatment due to disease progression. Informed consent must be obtained 
from any patient who agrees to provide tissue for this optional testing, including patients that continue after the FPV.
x
The end of study treatment visit tumour assessments do not need to be repeated if they were done during the previous 2 cycles (3 cycles if patient was on 
study for >1 year).
y
Follow-up assessments every 8 weeks (±1 week) from first dose (every 12 weeks for patients on study >1 year) until progression, death, or until the study is 
terminated by the sponsor.
z
An optional PGx sample will be collected from consenting patients.  If not collected at Cycle 1 Day 1, the PGx sample may be collected at any visit until the 
last study visit (see Section 3.3).
aa
Complete blood counts (CBC) will be obtained for all patients at the beginning of each treatment week and reviewed prior to dose administration.  If 
haematologic toxicity occurs, treatment should be held and ANC and platelets should be monitored at least weekly.  Patients should be managed as 
medically indicated.  Treatment should not be resumed until recovery to Grade 1 (ANC ≥1.5 x 109/L or 1,500/μL; platelets ≥75,000/μL) (see Section 6.9.1

AZD1775 ± chemotherapy.  The EOT visit is not required for patients continuing treatment after the FPV.  SAEs and pregnancy test results will be 
collected for 30 days following the patient’s last dose of AZD1775 ± chemotherapy.

a
The physical examination, vital signs, medical history (capture previous treatment medications and response to each prior treatment regimen), concomitant 
medications (recorded ≤14 days prior to trial entry), ECOG PS, complete blood count (CBC) with differential and platelets, clinical chemistry, urinalysis, 
and 12-lead triplicate ECG should be done ≤7 days prior to initiation of treatment.  However, if any of these initial examinations are required at Cycle 1 Day 
1 and are obtained within 3 days prior to the initiation of treatment they do not have to be repeated.  If an ECG is done ≤7 days prior to initiation of 
treatment, then it does not need to be repeated pre-dose on C1D1.  CA-125 should be done within 14 days prior to the initiation of treatment.  Scans to 
document evaluable disease (i.e., tumour measurement) should be performed ≤28 days prior to initiation of treatment and should be performed as close to 
the start of treatment as possible.  
b
All patients must provide an archival tumour for TP53 testing and other exploratory biomarkers by a central laboratory(see Section 5.6).    
c
Vital signs (resting heart rate, blood pressure, temperature and weight) at the Screening visit will include height.  After Screening, height will not be 
measured.  Vital signs and weight will be obtained prior to chemotherapy administration according to institutional practice.  
d
Clinical chemistry will include measurements of glucose, BUN, creatinine, sodium, potassium, chloride, calcium, CO2, ALP, AST, ALT, total bilirubin, 
total protein, lactate dehydrogenase (LDH), phosphorus, and albumin.  
e
Coagulation performed at baseline only (PT or INR with PTT) should be done ≤7 days prior to initiation of treatment.  Repeat at the beginning of every 
cycle if patient on Coumadin.
f
QTc interval will be calculated using Fridericia's formula (as calculated per institutional standards) obtained from 3 ECGs 2-5 minutes apart at study entry 
(see Section 3.2). An ECG will be collected at baseline to calculate the QTc interval and confirm eligibility (see Section 3.2). Thereafter, patients will have 
triplicate ECG on C1D1 (pre-dose, 2 and 4 hr post-dose) and C1D3 (pre-dose, and 2 hours and 4 hours post-dose) and on C3D3 (pre-dose only).  In 
addition, patients will have triplicate 12-lead ECGs performed 2-5 minutes apart at the beginning of each treatment cycle.
g
Pregnancy tests will only be performed in WoCBP within 3 days of starting study treatment and confirmed prior to start of study treatment on the first day 
of dosing.  WoCBP must have a negative pregnancy test prior to starting each new treatment cycle and at the end-of-treatment visit (see Section 3.8).
h
Patients will be restaged after every 2 cycles (every 8 weeks [±7 days]).  Patients with PD or unacceptable toxicity should be discontinued from the study; 
patients with SD or response to therapy will continue treatment.
i
CT scans/MRIs of the chest and abdomen and pelvis are required at baseline and every 2 cycles (8 weeks).      
j
The same method of assessment and the same technique must be used to characterise each identified and reported lesion at baseline and during subsequent 
imaging procedures.  Patients continuing study treatment beyond 1 year may have the tumour imaging assessments expanded to every 3 cycles (12 weeks 
[±7 days]).
k
Patients without evidence of undue toxicity may continue treatment with study drugs until disease progression occurs as long as they are achieving clinical 
benefit and desire to continue therapy.  
l
The End of Study Treatment Visit will be performed 30 days after the last dose of study treatment or prior to the beginning of new therapy.  Reassessments 
for toxicity, disease progression, and survival will be performed 30 days from last treatment dose (see Section 7.2.7).  Tumour assessments will be repeated 
at the end of study treatment visit if they have not been performed within the past 2 cycles (3 cycles for patients on study for >1 year).
m
Post follow-up for patients without disease progression at the time of study drug discontinuation should include repeat CT scan(s) and CA-125 (if 
applicable) until disease progression has been observed.  The patient will be followed every 3 months (±1 week) from the date of the last tumour assessment 
and assessment of response, until death or until the study is terminated by the sponsor.    
n
Patients with documented disease progression will be followed every 3 months (±1 week) for survival status (e.g., date and cause of death).  Patients may be 
contacted during outpatient visits or by telephone.  All post study therapies and dates of administration will be collected.
o
CA-125 serum sample collected at baseline (within 14 days prior to first study treatment), Day 1 of each cycle, and end-of-study treatment visit (see Section 
5.1).

p
Left ventricular cardiac function (e.g. MUGA or echocardiogram [ECHO]) will be assessed at baseline, every 6 cycles or as clinically indicated based on 
prior anthracycline exposure and clinical symptoms.  End of treatment assessment should be done for patients who receive at least 3 cycles of treatment and 
have not had an ECHO done in the past three months.  
q
All patients will have limited plasma PK analysis.  Samples will be collected as follows:
PK samples for PLD will be collected on Cycle 1, Day 1: 0 (pre-dose), and 0.5, 1, 2, 6, 24 h, 48 h, 7d and 14d after infusion start (Table 10 and Table 11); 
Additional PK samples for PLD will be collected pre-dose & 1 hour post-dose time point on Day 1 of alternate cycles, starting from Cycle 3 (Cycles 3, 5, 7 
etc.) (Table 13).  PK samples for AZD1775 will be collected on Cycle 1 Day 3 (0, 1, 2, 4, 6, and approximately 8 hrs post-dose) (Table 12) 
Additional PK samples for AZD1775 will be collected pre-dose on Day 3 on alternate cycles, starting from Cycle 3 (Cycles 3, 5, 7 etc.) (Table 13).
r
Collection of cfDNA to explore the genetic tumour markers in plasma correlation with markers in tumour samples and to monitor for the emergence of 
resistance is mandatory at baseline, Cycle 2 Day 1, restaging, end-of-treatment and progression for all patients.  Plasma samples will be collected in an 
EDTA tube and processed according to the Laboratory Manual.  See Section 5.6 for more information.
s
Patients with elevated CA-125 levels that can be monitored for response will be assessed according to the GCIG CA-125 response criteria in addition to 
RECIST v1.1.  An additional sample will be collected for tumour response monitoring.  Patients can be evaluated according to CA-125 only if they have a 
pre-treatment sample that is at least twice the ULN and within 2 weeks prior to starting treatment (see Section 5.1
t
Five doses of AZD1775 (175 mg or 225 mg PO) will be taken within 3 consecutive days (at least 12 hours apart).  AZD1775 should be taken approximately 
2 hours before or 2 hours after food.
u
Review and document AZD1775 dosing compliance with the patient at the beginning of each new treatment cycle when study drug is dispensed.  
v
PLD 40 mg/m2 IV will be administered according to institutional standards on Days 1 of each 28 day cycle.
w
Optional tumour biopsy samples will be requested from patients at the time of disease progression.  Informed consent must be obtained from any patient 
who agrees to provide tissue for this optional testing.  
x
The end of study treatment visit tumour assessments do not need to be repeated if they were done during the previous 2 cycles (3 cycles if patient was on 
study for >1 year).
y
Follow-up assessments start 12 weeks from the last date tumour and response assessments were performed.

4.1
Screening period
Procedures will be performed according to the Study Plan.  At screening, consenting subjects 
are assessed to ensure that they meet eligibility criteria. Subjects who do not meet these 
criteria must not be enrolled in the study.  
4.2
Treatment period
A patient is defined as being on-study if they are continuing to have any study data collected, 
if the patient is receiving study specific treatment, is being followed for efficacy after 
discontinuation of protocol specific treatment, or is in follow-up.  Descriptions of the 
procedures for this period are included in the Study Plan. 
4.3
Follow-up period
Patients discontinuing study treatment should be scheduled for an end-of-treatment (EOT) 
visit, approximately 30 days after the study drug is permanently discontinued unless the 
patient withdraws consent.
Approximately 30 days after the last treatment, patients will return to the clinic for a follow-
up assessment.  The primary purpose of this visit is to follow-up any AEs ongoing at the time 
of discontinuation and to assess any new AEs that may have occurred since discontinuation.  
Any AE, SAE, abnormal laboratory findings that are ongoing at the time of study treatment 
discontinuation or any new events within 30 days of last study treatment, must be followed up 
to resolution or until the event becomes stable (or returns to baseline) or is unlikely to resolve 
further in the opinion of the Investigator.
Patients who discontinue study treatment prior to the occurrence of disease progression will be 
followed every 8 weeks (±1 week) from first dose (every 12 weeks for patients on study >1 
year), until progression, death, or until study is terminated by sponsor.  The exception is for 
Arm C, which will be followed every 6 weeks (±1 week) from first dose (every 9 weeks for 
patients on study >1 year), until progression, death, or until the study is terminated by the 
sponsor.
Patients with documented disease progression will be followed every 3 months for survival 
status (e.g., date and cause of death) for up to 2 years, death, or until time of final data 
collection for the progression-free survival analysis, whichever comes first.  Patients may be 
contacted during outpatient visits or by telephone.  Information pertaining to the type and 
dates of administration of post-study therapy will be collected when available.

Final Protocol Visit and Beyond
The Final Protocol Visit (FPV) requirement applies only to those patients who will be 
receiving AZD1775 ± chemotherapy after the time of primary data cut-off meant for the 
preparation of the CSR.
Any patients receiving AZD1775 ± chemotherapy at the time of the primary data cut-off will 
complete a FPV, which should occur at the next scheduled visit following implementation of 
the Revised Protocol Edition 10.
Beyond the FPV, patients may continue to receive AZD1775 ± chemotherapy if they are 
deriving clinical benefit, in the opinion of the Investigator, and not fulfilling any of the 
discontinuation criteria.  Combining AZD1775 with a different anti-cancer therapy is not 
allowed.  Such patients are to be treated as deemed appropriate by the Investigator to ensure 
continued safety monitoring of the patient while receiving the investigational product.  It is 
recommended to continue observing ongoing patients at the frequency indicated within the 
study plans as described in Table 2, Table 3 and Table 4.  Restrictions regarding concomitant 
medications (refer to Section 7.7.2) will be followed while the patient is receiving 
AZD1775 ± chemotherapy.  A change in AZD1775 ± chemotherapy dose/schedule should 
only occur for safety reasons, based on the Investigator’s judgement, and should generally 
follow the approach for dose reduction and discontinuation as described in this protocol.  
After the FPV, SAEs, drug accountability, overdoses and pregnancy test results will be 
collected while the patient is receiving AZD1775 ± chemotherapy.  
If a patient is no longer receiving benefit from AZD1775 ± chemotherapy beyond the FPV in 
the opinion of the treating physician, then the study drug should be stopped.  The Investigator 
will inform AstraZeneca when a patient discontinues the study drug.  Patients must return 
unused medication when they discontinue treatment.  In addition, provided that a patient gives 
proper informed consent, a plasma isolation (cfDNA) blood sample and optional tumour 
biopsy for future biomedical research should be obtained at the time of 
AZD1775 ± chemotherapy discontinuation, if due to disease progression.  SAEs and 
pregnancy test results will be collected for 30 days following the patient’s last dose of 
AZD1775 ± chemotherapy.

(CSA). The Investigator will sign the completed eCRFs.  A copy of the completed eCRFs 
will be archived at the study site.
5.1
Efficacy assessments
Tumour assessments
RECIST v1.1 criteria will be used to assess patient response to treatment by PFS, ORR and 
DCR.  The RECIST v1.1 guidelines for measurable, non-measurable, target lesions (TLs) and 
non-target lesions (NTLs) and the objective tumour response criteria (CR, PR, SD or 
progression of disease) are presented in Appendix E.
The same method of assessment of tumour burden used at baseline (CT scans or magnetic 
resonance imaging [MRI] of the chest and abdomen/pelvis) must be used at each subsequent 
follow-up assessment (see Table 1 – Table 4).  CT scan or MRI of chest and abdomen/pelvis 
are mandatory and must be repeated every 2 cycles.  Patients will be assessed for biochemical 
response (CA-125) at baseline, Day 1 of each cycle, at the end of study treatment visit and the 
FPV.  
Following the baseline assessment, efficacy for all patients will be assessed by objective 
tumour assessments after start of treatment until objective disease progression as defined by 
RECIST v1.1 or withdrawal from study.  For patients in Arm C, objective tumour assessments 
will be done every 6 weeks (± 1 week) (2 cycles).  For patients in Arms A, B, and D, objective 
tumour assessments will be done every 8 weeks (±1 week) (2 cycles). 
Categorisation of objective tumour response assessment will be based on the RECIST v1.1 
criteria of response: CR (complete response), PR (partial response), SD (stable disease) and
PD (progression of disease).  Target lesion progression will be calculated in comparison to 
when the tumour burden was at a minimum (i.e. smallest sum of longest diameters previously 
recorded on study).  In the absence of progression, tumour response (CR, PR, or SD) will be 
calculated in comparison to the baseline tumour measurements obtained before starting 
treatment.
If the Investigator is in doubt as to whether progression has occurred, particularly with regard 
to NTLs 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 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 Table 1, Table 2, Table 3, or Table 4.  Patients will be assessed by standard 
criteria.  For the purposes of this study, patients should be evaluated for radiographic tumour 
response every six or eight weeks (±1 week [cycle length dependent]).  The same method of 
assessment and the same technique should be used to characterize each identified and reported 
lesion at baseline and throughout the study.  Overall tumour response and progression will be 
calculated according to RECIST 1.1 (see Appendix E), at the designated time points.  Patients 
continuing study treatment beyond one year may have tumour assessments expanded to be 
repeated every 9 or 12 weeks instead of every 6 or 8 weeks.
Tumour status will be compared to baseline and confirmation of response will be evaluated by 
physical examination, anatomic imaging measurement, and performance status.
Patients with elevated CA-125 levels that can be monitored for response will be assessed 
according to the GCIG CA-125 response criteria in addition to RECIST v1.1. 
GCIG Criteria
The GCIG has agreed criteria for defining response and progression of ovarian carcinoma 
which use the serum marker CA-125 and the situations where these criteria should be used.  
The GCIG recommends that for trials of relapsed ovarian cancer the following definition for 
response according to CA-125 be used in addition to RECIST v1.1 response criteria (Rustin et 
al 2011).
Evaluation of Response according to CA-125
Definition of response:  A response according to CA-125 has occurred if there is at least a 
50% reduction in CA-125 levels from a pre-treatment sample. The response must be 
confirmed and maintained for at least 28 days.  Patients can be evaluated according to CA-125 
only if they have a pre-treatment sample that is at least twice the ULN and within 2 weeks 
prior to starting treatment.
To calculate CA-125 responses accurately, the following rules apply: 
∀
Intervening samples and the 28-day confirmatory sample must be less than or equal 
to (within an assay variability of 10%) the previous sample.
∀
Variations within the normal range of CA-125 levels will not interfere with the 
response definition. 
∀
For each patient, it is preferred that the same assay method be used, and the assay 
must be tested in a quality-control scheme.

AstraZeneca
AZD1775 - D6010C00004
Version 10, 05 September 2018
CONFIDENTIAL AND PROPRIETARY
62 of 153
∀
Patients are not evaluable (NE) by CA-125 if they have received mouse antibodies 
(unless the assay used has been shown not to be influenced by HAMA [1, 2]) or if 
there has been medical and/or surgical interference with their peritoneum or pleura 
during the previous 28 days.  If assessing therapy that includes two treatment 
modalities for relapse (e.g., surgery and chemotherapy), any CA-125 response results 
from both treatments modalities.  CA-125 cannot distinguish between the effects of 
the two treatments.
The date when the CA-125 level is first reduced by 50% is the date of the CA-125 response. 
To calculate RRs, an intent-to-treat analysis should be used that includes all patients with an 
initial CA-125 level of at least twice the ULN as eligible and evaluable.  In addition, as a 
separate analysis, those patients who have both a CA-125 response and whose CA-125 level 
falls to within the normal range, can be classified as CA-125 complete responders.  Patients 
who have a fall of CA-125 to within the normal range but whose initial CA-125 was less than 
twice the ULN, have not had a CA-125 response and cannot therefore be classified as a CA-
125 complete responder.
5.2
Safety assessments
A physical examination, medical history (to capture previous treatment medications and 
response to each prior treatment regimen), concomitant medications recorded (including ≤14 
days prior to trial entry), ECOG PS, complete blood count (CBC) with differential and 
platelets, clinical chemistry, and 12-lead ECG should be done at screening, at the beginning of 
each treatment cycle, and at the FPV according to the study plan.  Assessments at other time 
points are indicated in the study plan. 
Vital signs (resting heart rate, blood pressure, temperature) and weight will be recorded at 
screening and at times shown in the study plan. 
The following are AZD1775 project related assessments that should be carried out in addition 
to any standard protocol monitoring such as routine haematology/biochemistry, vital signs, 
and physical examinations.
5.2.1
Laboratory safety assessments
Blood samples for determination of clinical chemistry, haematology, coagulation, and PK will 
be performed at the times indicated in the Study Plan (Table 1-Table 4) and PK assessment 
schedule (Table 6-Table 13).
Additional safety samples may be collected as clinically indicated and at the discretion of the 
Investigator. The date, time of collection and results (values, units and reference ranges) will 
be recorded on the appropriate eCRF.

FPV. In the event of suspected pregnancy during the study, the test should be repeated and, if 
positive, the patient discontinued from study treatment immediately.
The Investigator should make an assessment of the available results with regard to clinically 
relevant abnormalities.  Any clinically significant abnormal laboratory values should be 
repeated as clinically indicated and recorded on the eCRF. The laboratory results should be 
signed and dated and retained at centre as source data for laboratory variables.  For

NB. In case a subject shows an AST or ALT ≥3xULN AND total bilirubin ≥ 2xULN please 
refer to Appendix C, ‘Actions required in cases of combined increase of Aminotransferase and 
Total Bilirubin – Hy’s Law’, for further instructions.
5.2.2
Physical examination
A complete physical examination will be performed and include an assessment of the 
following: general appearance, respiratory, cardiovascular, abdomen, skin, head and neck 
(including ears, eyes, nose and throat), lymph nodes, thyroid, musculo-skeletal (including
spine and extremities) and neurological systems. 
If new or aggravated physical findings imply deterioration compared with baseline, the 
finding should be reported as an AE (Section 6.4).  Performance status will be assessed using 
the ECOG performance status criteria.
5.2.3
ECG
An ECG will be performed at baseline as indicated in the Study Plans.  QTc interval will be 
calculated using Fridericia's formula (per institutional standards) obtained from 3 ECGs 
performed 2-5 minutes apart at study entry.  Thereafter, triplicate 12-lead ECGs will be 
performed 2-5 minutes apart prior dosing on Day 1 of each treatment cycle and the FPV.
Attention should be paid to any detected increases in QTc interval.  Patients who develop a 
single resting value of QTc interval of >470 msec/female or a shift from baseline of 60 ms 
should stop taking AZD1775.  Dosing can be resumed at a reduced dose (see Section 6.9.2) 
after return of the resting QTc interval to pre-treatment status has been confirmed and 
correction of possible electrolyte imbalance has been made.
Monitoring of QTc, checking and correction of abnormal electrolyte levels and renal function 
are advised, especially in case of severe/prolonged diarrhoea.  If QTc increases markedly from 
baseline, but stays below the above limits, a cardiologist’s advice should be sought.
The concomitant use of ondansetron (known to prolong the QTc interval in rare cases, per 
labelling) should be taken into account when interpreting QTc changes.
5.2.4
CA-125 tumour markers
Serum samples will be collected for CA-125 tumour markers on all patients at baseline 
(within 14 days prior to Cycle 1 Day 1), Day 1 of each cycle, end-of-study treatment visit, and 
the FPV.  The CA-125 analysis will be performed by a local laboratory.  Patients with 
elevated CA-125 levels that can be monitored for response will be assessed according to the 
GCIG CA-125 response criteria in addition to RECIST v1.1.

To characterise the exposure of all analytes to help determine the cause of any adverse 
effects observed in the safety cohort
!
To assess the drug interaction between AZD1775 plus carboplatin, AZD1775 plus 
paclitaxel, AZD1775 plus gemcitabine, and AZD1775 plus PLD
!
To provide exposure data for AZD1775 which can be included with that from other 
studies for overall population PK (POPPK) analysis to help understand the PKs of the 
compound and identify covariates. 
During Cycle 1, the PK collection schedule will vary with the treatment arm reflecting the 
different PKs of the 4 chemotherapeutic agents (see Table 6, Table 7, Table 8, Table 10, Table 
11, Table 12, and Table 13).  AZD1775 will be given at the start of each cycle, which also 
defines the start of PK sampling for all analytes.  The chemotherapeutic agent infusion will 
start at the same time AZD1775 is dosed.  PK collections for additional cycles are presented in 
Table 9 and Table 13).
The following information will be recorded each time a PK sample is collected:
∀
Date and actual time of the PK sample collection
∀
Date and time of the AZD1775 dose preceding PK collection
∀
Date and time of the start and end of infusion of the relevant chemotherapeutic agent
∀
Time and date of last meal

If a patient’s dosing regimen is altered, the PK sampling regimen will be appropriately 
amended to characterise PK profiles.  Equivalent PK samples will be required if an additional 
lead-in safety/expansion cohort is necessary.
Samples will be collected, labelled, stored and shipped as detailed in the Laboratory Manual. 
5.3.2
Determination of drug concentration
Samples for determination of AZD1775 concentrations in plasma will be analysed by 
Covance on behalf of AstraZeneca using an appropriate bioanalytical method.  Additional 
analyses may be conducted on the biological samples to further investigate the presence 
and/or identity of drug metabolites.  Full details of the analytical method used will be 
described in a separate bioanalytical report.  The data may be compared by visual inspection 
to broadly compare exposure to historic monotherapy or other data.  The analysis of the PK 
samples may be expedited if tolerance, safety or other issues are suspected to be related to, or 
have caused changes in the exposure of AZD1775.  From a PK modelling perspective, this 
data will be used for pooling with PK data collected from other AZD1775 studies in order to 
perform a population PK analysis using non-linear mixed effects modelling.  This data
together with safety and pharmacodynamics (PDx) data may be used as part of a future 
exploratory PK/PDx analysis which will be reported separately from the CSR.
Plasma concentrations of gemcitabine (and 2’Difluoro-2’2’-deoxyuridine), paclitaxel, total 
platinum, and total doxorubicin will be analysed by Covance on behalf of AstraZeneca and 
used to compare exposure and PKs to published data.  Other drug related components may be 
measured if required.

5.3.3
Storage and destruction of pharmacokinetic samples
Pharmacokinetic samples will be disposed of after the Bioanalytical Report finalization or six 
months after issuance of the draft Bioanalytical Report (whichever is earlier), unless requested 
for future analyses. Any pharmacokinetic sample remaining after analysis for AZD1775 may 
be used for exploratory drug-drug interaction (DDI), metabolite, or biomarker analyses.  Any
results from such analyses may be reported separately from the CSR.
Additional analyses may be conducted on the anonymised, pooled PK samples to further 
evaluate and validate the analytical method. Any results from such analyses may be reported 
separately from the CSR. 
Incurred sample reproducibility analysis, if any, will be performed alongside the bioanalysis 
of the test samples. The results from the evaluation will not be reported in the CSR but 
separately in a Bioanalytical Report.
Any residual back-up PK samples will be disposed of after the CSR is finalized.

Pharmacodynamics
5.4.1
Collection of samples
Pharmacodynamic samples will not be taken during the study.
5.5
Pharmacogenetics
5.5.1
Background and rationale
AstraZeneca intends to perform genetic research in the AZD1775 clinical development 
programme to explore how genetic variations may affect the clinical parameters associated 
with AZD1775 when combined with chemotherapy.  Collection of DNA samples from 
populations with well-described clinical characteristics may lead to improvements in the 
design and interpretation of clinical trials and, possibly, to genetically guided treatment 
strategies.  Future research may suggest other genes or gene categories as candidates for 
influencing not only response to AZD1775 but also susceptibility to or evolution of ovarian 
cancer/cancer studies, for which AZD1775 is being evaluated.  Thus, this genetic research 
may involve study of additional un-named genes or gene categories, but only as related to 
disease susceptibility to or evolution of ovarian cancer/cancer studies, and drug action.
5.5.2
Pharmacogenetic research objectives
The objective of this research is to collect and store DNA for future exploratory research into 
genes/genetic variation that may influence response (e.g., distribution, metabolism, safety, 
tolerability and efficacy) to AZD1775, as well as susceptibility to disease evolution of ovarian 
cancer studies and drug action.

Clinical Study Protocol

AZD1775 - D6010C00004
Version 10, 05 September 2018
CONFIDENTIAL AND PROPRIETARY
71 of 153
The benefits of being able to explore associations between genes and clinical outcomes within 
the AZD1775 programme are potentially many, and include:
!
Analysis of genes that may affect efficacy, safety, and tolerability of AZD1775 when 
combined with chemotherapy (for example, but not limited to, drug metabolising 
enzymes and drug transporters).
!
Genetic research into genes that may contribute to the development or evolution of, or 
susceptibility to ovarian cancer/cancer studies.
5.5.3
Genetic Research Plan and Procedures
Selection of genetic research population
Patients will be asked to participate in this genetic research.  Participation is voluntary and if a 
patient declines to participate there will be no penalty or loss of benefit.  The patient will not 
be excluded from any other aspect of the main study.
5.5.4
Discontinuation of patients from this genetic research
Patients may withdraw from this genetic research at any time, independent of any decision 
concerning participation in other aspects of the main study.  Voluntary discontinuation will 
not prejudice further treatment.
5.5.5
Collection of pharmacogenetic samples
The patient’s consent to participate in the pharmacogenetic research components of the study 
is optional; however, for inclusion in this optional research, patients must provide informed 
consent.  
The blood sample (approximately 10 mL) for genetic research will be obtained from the 
patients at screening, prior to their first dose of study drug.  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 prior to the first 
dose of study drug, it may be taken at any visit until the last study visit.  Only one sample 
should be collected per patient for genetic research during the study. 
Samples will be collected, labelled, stored and shipped as detailed in the Laboratory Manual.
5.5.6
Storage, re-use and destruction of 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 from the date of the Last Patient’s Last Visit, after which they will be destroyed.  DNA 
is a finite resource that may be used up during analyses.  The results of any further analyses 

Clinical Study Protocol

will be reported either in the Clinical Study Report itself or as an addendum, or separately in a 
scientific report or publication.
For all samples 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.
5.5.7
Ethical and Regulatory Requirements
The principles for ethical and regulatory requirements for the study, including this genetics 
research component, are outlined in Section 10.
5.5.8
Informed consent
The genetic component of this study is optional and the patient may participate in other 
components of the main study without participating in the genetic component.  To participate 
in the genetic component of the study the patient must sign and date both the consent form for 
the main study and the genetic component of the study.  Copies of both signed and dated 
consent forms must be given to the patient and the originals filed at the study centre.  The 
principal investigator(s) is responsible for ensuring that consent is given freely and that the 
patient understands that they may freely discontinue from the genetic aspect of the study at 
any time.
5.5.9
Patient data protection
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 

Clinical Study Protocol
AstraZeneca

Version 10, 05 September 2018
CONFIDENTIAL AND PROPRIETARY
73 of 153
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.
5.5.10
Data management
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 the 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.
5.5.11
Statistical Methods and Determination of Sample Size
The number of patients that will agree to participate in the genetic research is unknown.  It is 
therefore not possible to establish whether sufficient data will be collected to allow a formal 
statistical evaluation or whether only descriptive statistics will be generated.  A statistical 
analysis plan will be prepared where appropriate.
5.6
Biomarker analysis 
The patient’s consent to the use of donated biological samples is mandatory.  
Biological samples (e.g., archived tumour samples and cfDNA) will be collected and may be 
analysed for exploratory biomarkers to assess correlations with disease activity, effects of 
study drug, clinical outcomes and toxicity.
5.6.1
Circulating free tumour DNA samples
Collection of cfDNA is mandatory at baseline, Cycle 2 Day 1, Day 1 of every odd-numbered 
cycle (Cycles 3, 5, etc.), end-of-study treatment visit, and at treatment discontinuation due to 
progression for all patients continuing treatment after the FPV in order to explore the genetic 
tumour markers in plasma, correlate with markers in tumour samples and to monitor for the 
emergence of resistance.  A baseline plasma sample will be required and subsequent plasma 
samples collected as described in the Laboratory Manual.  This exploratory analysis will be 
reported separately from the Clinical Study Report (CSR).

5.6.2
Optional tumour biopsies
Optional tumour biopsies during this study will be requested from consenting patients with 
easily accessible tumours who discontinue treatment due to disease progression including 
from consenting patients that continue treatment after the FPV.
The tumour biopsy procedure will be performed by core needle, under radiological guidance, 
or surgically if the site of disease is superficial and palpable or visible.  It is mandated that the 
core biopsy be removed directly from the tumour in situ and not cored from a surgically 
removed tumour.  This is to ensure the best possible quality of the biopsy, as the 
blood/nutrient supply to the tumour is not disrupted prior to biopsy collection.  
All tumour biopsies will be collected, stored, and shipped as detailed in the Laboratory 
Manual.
Any residual samples remaining after analysis will be retained for any potential subsequent 
retrospective analysis of other response related and/or cancer related biomarkers.  It is not 
intended that data derived from residual sample analysis will be reported in the CSR.
Informed consent must be obtained from any patient who agrees to provide tissue for tumour 
tissue sample testing.
5.6.3
Storage, re-use and destruction of biological samples
Samples will be stored for a maximum of 15 years from the date of the Last Subject’s Last 
Visit, after which they will be destroyed.  The results of this biomarker research will be 
reported either in the CSR itself or as an addendum, or separately in a scientific report or 
publication. The results of this biomarker research may be pooled with biomarker data from 
other studies with the study drug to generate hypotheses to be tested in future research.
5.6.4
Labelling and shipment of biological samples
The Principal Investigator (PI) 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 B, ‘IATA 6.2 Guidance Document’).
Any samples identified as Infectious Category A materials are not shipped and no further 
samples will be taken from the subject unless agreed with AstraZeneca and appropriate 
labelling, shipment and containment provisions are approved.
5.6.5
Chain of custody of biological samples 
A full chain of custody is maintained for all samples throughout their lifecycle.

The PI at each centre keeps full traceability of collected biological samples from the subjects 
while in storage at the centre until shipment or disposal (where appropriate) and keeps 
documentation of receipt of arrival.
The sample receiver keeps full traceability of the samples while in storage and during use until 
used or disposed of or until further shipment.
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.
5.6.6
Withdrawal of Informed Consent for donated biological samples 
If a subject 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 some of the biological samples is an optional part of the study, then the 
subject may continue in the study.
The PI:
!
Ensures subjects’ withdrawal of informed consent to the use of donated samples is 
notified immediately to AstraZeneca
!
Ensures that biological samples from that subject, if stored at the study site, are 
immediately identified, disposed of /destroyed, and the action documented
!
Ensures the laboratory(ies) holding the samples is/are informed about the withdrawn 
consent immediately and that samples are disposed of/destroyed, the action documented 
and the signed document returned to the study site
!
Ensures that the subject 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.

Data collection of safety-related study variables 
6.1.1
Adverse events of special interest related to AZD1775
There are no AESI for AZD1775 which require additional data collection.
6.2
Definition of adverse events
An AE is the development of an undesirable medical condition or the deterioration of a pre-
existing medical condition following or during exposure to a pharmaceutical product, whether 
or not considered causally related to the product.  An undesirable medical condition can be 
symptoms (e.g., nausea, chest pain), signs (e.g., tachycardia, enlarged liver) or the abnormal 
results of an investigation (e.g., laboratory findings, ECG).  In clinical studies, an AE can 
include an undesirable medical condition occurring at any time, including run-in or washout 
periods, even if no study treatment has been administered.
The term AE is used to include both serious and non-serious AEs.
6.3
Definitions of serious adverse event
An SAE is an AE occurring during any study phase (i.e., run-in, treatment, washout, follow-
up), that fulfils one or more of the following criteria:
!
Results in death
!
Is immediately life-threatening
!
Requires in-patient hospitalisation or prolongation of existing hospitalisation 
!
Results in persistent or significant disability/incapacity or substantial disruption of the 
ability to conduct normal life functions
!
Is a congenital abnormality or birth defect
!
Is an important medical event that may jeopardise the subject or may require medical 
intervention to prevent one of the outcomes listed above.
For further guidance on the definition of a SAE, see Appendix A to the Clinical Study 
Protocol (CSP).
6.4
Recording of adverse events
6.4.1
Time period for collection of adverse events
Adverse events will be collected throughout the study, from informed consent until 30 days 
after the end of the last investigational product administration. 
SAEs will be recorded from the time of informed consent and should be reported to the 
Innovations Safety Department as described in Section 6.5.  After the FPV, patients will 
continue to be monitored for all SAEs, overdoses and pregnancies while receiving 
AZD1775 ± chemotherapy and for 30 days after the last dose of AZD1775 ± chemotherapy.

Version 10, 05 September 2018
CONFIDENTIAL AND PROPRIETARY
77 of 153
Following discontinuation of study treatment, SAEs considered related to study procedures
should continue to be collected while patients are followed-up for disease progression.
For each patient who discontinues study treatment for a reason other than disease progression:
∀
Follow-up information on all ongoing AEs should continue to be collected until the 
survival follow-up.
∀
SAEs considered related to study procedures must continue to be collected and 
reported using standard SAE timelines and process until the end of progression 
follow-up (i.e., disease progression).
∀
All deaths must continue to be collected after progression and during the survival 
follow-up.
6.4.2
Follow-up of unresolved adverse events
Any AEs that are unresolved at the patient’s last visit in the study are followed up by the 
Investigator for as long as medically indicated, but without further recording in the eCRF. 
AstraZeneca retains the right to request additional information for any patient with ongoing 
AE(s) at the end of the study, if judged necessary.
If an Investigator learns of any SAEs, 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 AZD1775, the Investigator should notify Innovations.
6.4.3
Variables 
The following variables will be collect for each AE:
!
AE (verbatim)
!
The date when the AE started and stopped
!
CTCAE grade and changes in CTCAE grade  
!

Description of AE.
The grading scales found in the revised NCI CTCAE v4.03 will be utilized for all events with 
an assigned CTCAE grading.  For those events without assigned CTCAE grades, the 
recommendation in the CTCAE criteria should be utilized that converts mild, moderate and 
severe events.  A copy of the CTCAE version 4.03 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 6.3.  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.  
6.4.4
Causality collection
The Investigator will assess causal relationship between IP and each AE, and answer ‘yes’ or 
‘no’ to the question ‘Do you consider that there is a reasonable possibility that the event may 
have been caused by the IP?’
For SAEs causal relationship will also be assessed for other medication and study procedures.   
Note that for SAEs that could be associated with any study procedure the causal relationship is 
implied as ‘yes’.
A guide to the interpretation of the causality question is found in Appendix A to the CSP.
6.4.5
Adverse events based on signs and symptoms
All AEs spontaneously reported by the patient, reported in response to an open question from 
the study personnel or revealed by observation will be collected and recorded in the eCRF.  
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.

They do not include metastases of the original cancer.
6.4.6
Adverse events based on examinations and tests
The results from protocol mandated laboratory tests and vital signs will be summarised in the 
CSR.  Deterioration as compared to baseline in protocol-mandated laboratory values, vital 
signs and ECG should therefore only be reported as AEs if they fulfil any of the SAE criteria 
or are the reason for discontinuation of the study treatment unless clearly due to the 
progression of disease under study.
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 (e.g., 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.
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.
6.4.7
Hy’s Law
Cases where a subject shows elevations in liver biochemistry may require further evaluation 
and occurrences of AST or ALT ≥ 3 x ULN and total bilirubin ≥ 2 x ULN may need to be 
reported as SAEs.  Please refer to Appendix C for further instruction on cases of increases in 
liver biochemistry and evaluation of Hy’s Law.
6.4.8
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.

Events including diagnosis or signs and symptoms or the abnormal results of an investigation 
including those leading to hospitalization, which constitute or result from: 
(a) ‘unequivocal progression’ (i.e., representative of overall disease status change, not a 
single lesion increase) of non-measurable/non-target disease, 
or
(b) progression of malignancy under study (target disease)as determined per RECIST 1.1 
criteria, should not be reported as AEs or SAEs.  
Progression of the malignancy under study, including signs and symptoms of 
progression, should not be reported as a serious adverse events. Hospitalizations due 
to signs and symptoms of disease progression should not be reported as serious 
adverse events.
6.4.9
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 the 
administration of the study treatment and have been identified after the patient’s inclusion in 
this study. They do not include metastases of the original cancer.
6.4.10
Handling of deaths
All deaths that occur during the study or within the follow-up period after the administration 
of the last dose of study treatment must be reported as follows:
!
Death which is unequivocally due to disease progression should be communicated to the 
study monitor at the next monitoring visit and should be documented in the eCRF 
module, but should not be reported as a SAE during the study.
!
Where death is not clearly due to progression of the disease under study the AE causing 
the death should be reported by entering into the WBDC system as an SAE within 24 
hours.  The report should contain a comment regarding the co-involvement of progression 
of disease, if appropriate, and should assign a single primary cause of death together with 
any contributory causes.
!
Death with an unknown cause should always be reported as an SAE but every effort 
should be made to establish a cause of death.  A post-mortem may be helpful in the 
assessment of the cause of death, and if performed a copy of the post-mortem results 
(with translation of important parts into English) should be reported in an expedited 
fashion to an AstraZeneca representative within the usual timeframes. 
6.5
Reporting of serious adverse events
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 eCRF. For patients continuing after the

FPV (see Section 4.4), SAEs should be determined per protocol and must continue to be 
reported via the standard pharmacovigilance process (on paper) as stated below.  For medical 
emergencies, see below.
If any SAE occurs in the course of the study, then Investigators or other site personnel inform 
the appropriate Innovations Safety Department, the  AstraZeneca representative within one 
day i.e., immediately but no later than 24 hours of when he or she becomes aware of it.
The designated Innovations representative works with the Investigator to ensure that all the 
necessary information is provided within 24 hours of investigator awareness.
For fatal or life-threatening AEs where important or relevant information is missing, active 
follow-up is undertaken immediately.  Investigators or other site personnel inform Innovations
representatives of any follow-up information on a previously reported SAE within one 
calendar day i.e., immediately but no later than 24 hours of when he or she becomes aware 
of it.
SAE information will be sent via secure e-mail connection or via fax.  The Innovations Safety 
Department standard paper SAE Report with supporting relevant source documents (e.g. 
history and physical [H&P], hospital discharge summary, autopsy report when available, 
results of relevant diagnostic tests completed to evaluate the event) will be attached and sent 
via:

Follow-up information for SAEs and information on non-serious AEs that become serious 
should also be reported to the Innovations Safety Department as soon as it is available; these 
reports should be submitted using the Innovations SAE Report Form.  The detailed SAE 
reporting process will be provided to the sites in the SAE reporting guidelines contained in the 
trial reference manual.
The appointed study Medical Monitor works with the Investigator to ensure that all necessary 
information is provided to the Innovations Safety Department within 24 hours of

threatening AEs for which important or relevant information is missing, active follow-up is 
undertaken immediately.   
AstraZeneca or their representative will provide Regulatory Authorities, Ethics Committees 
(ECs), IRBs and PIs with clinical safety updates/reports according to local requirements. 
6.6
Overdose
A dose of AZD1775 in excess of that specified according to the protocol will constitute an 
overdose.  There is currently no known antidote to AZD1775, and the treatment of overdose 
should be supportive for the underlying symptoms.  To date, there has been one patient who 
has experienced an overdose with AZD1775 which was associated with adverse events.
Overdoses with non-AZ products used in combination or comparative studies should be 
managed according to the product label.  
Such overdoses should be recorded as follows:
!
An overdose with associated AEs is recorded as the AE diagnosis/symptoms on the 
relevant AE modules in the eCRF and on the Overdose eCRF module.
!
An overdose without associated symptoms is only reported on the Overdose eCRF 
module.
If an overdose of AZD1775 occurs in the course of the study, then the Investigator or other 
site personnel will inform the Innovations Safety Department immediately, or no later than 
24 hours of when he or she becomes aware of it.
The Innovations Safety Department representative works with the Investigator to ensure that 
all relevant information is provided to the AstraZeneca Patient Safety data entry site.
For overdoses associated with a SAE, the standard reporting timelines apply, see Section 6.5.  
For other overdoses, reporting must occur within 24 hours.
6.7
Pregnancy
All pregnancies and outcomes of pregnancy should be reported to the Innovations Safety 
Department.  After the FPV, pregnancies will be monitored while patients are on treatment 
and for 30 days after their final dose of AZD1775 ± chemotherapy.
6.7.1
Maternal exposure
If a subject becomes pregnant during the course of the study, IP should be discontinued 
immediately.  Pregnancy itself is not regarded as an AE 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 subject was discontinued from the study.
If any pregnancy occurs in the course of the study, then the Investigator or other site personnel 
informs the appropriate Innovations Safety Department representatives within 1 day (i.e., 
immediately but no later than 24 hours) of when he or she becomes aware of it.
!
The designated Innovations Safety Department representative works with the Investigator 
to ensure that all relevant information is provided to the AstraZeneca Patient Safety data 
entry site within 1 or 5 calendar days for SAEs (see Section 6.5) and within 30 days for 
all other pregnancies.
The same timelines apply when outcome information is available.
6.8
Medication error
For the purposes of this clinical study, a medication error is an unintended failure or mistake 
in the treatment process for the study drug(s) that either causes harm to the patient or has the 
potential to cause harm to the patient.
A medication error is not lack of efficacy of the drug, but rather a human or process related 
failure while the drug is in control of the study site staff or patient.
Medication error includes situations where an error has:
!
occurred
!
was identified and intercepted before the patient received the drug
!
did not occur, but circumstances were identified that could have led to an error
Examples of events to be reported in clinical studies as medication errors:
!
Drug name confusion
!
Dispensing error e.g., medication prepared incorrectly, even if it was not actually given to 
the patient
!
Drug not administered as indicated, for example, wrong route or wrong site of 
administration
!
Drug not taken as indicated e.g., tablet dissolved in water when it should be taken as a 
solid tablet
!
Drug not stored as instructed e.g., kept in the fridge when it should be at room 
temperature
!
Wrong patient received the medication

!
Wrong drug administered to patient
Examples of events that do not require reporting as medication errors in clinical studies: 
!
Patient accidentally missed drug dose(s) e.g., forgot to take medication
!
Accidental overdose (will be captured as an overdose)
!
Patient failed to return unused medication or empty packaging
!
Errors related to background and rescue medication, or standard of care medication in 
open label studies, even if an AZ product
Medication errors are not regarded as AEs but AEs may occur as a consequence of the 
medication error.
If a medication error occurs in the course of the study, then the Investigator or other site 
personnel informs the Innovations representatives within 1 day, i.e., immediately but no later 
than 24 hours of when he or she becomes aware of it.  The Innovations representative works 
with the Investigator to ensure that all relevant information is completed within 1 to 5 calendar 
days if there is an SAE associated with the medication error (see Section 6.3) and within 30 
days for all other medication errors.
6.9
Management of IP related toxicities / Dose Reductions
Toxicity will be assessed utilizing the NCI CTCAE v4.03 
(http://evs.nci.nih.gov/ftp1/CTCAE/CTCAE_4.03_2010-06-14_QuickReference_5x7.pdf), 
unless otherwise specified.  
The DLT evaluations (see Section 7.2.4) will be used to assess the first 6 patients during 
Cycle 1.  Toxicity occurring in patients beyond Cycle 1 of the Part 1 lead-in safety phase will 
be graded and the appropriate dose modification or supportive care will be administered to 
decrease the signs and symptoms thereof according to this section.  
Dose adjustments will be based on the organ system exhibiting the greatest degree of toxicity.  
Dose reductions or holds and initiation of supportive care are allowed as clinically indicated 
by the treating physician.  A maximum of 2 dose reductions for the AZD1775 and 
chemotherapy will be allowed.  For patients experiencing toxicity while taking AZD1775 over 
2.5 days weekly the Investigator should contact the Medical Monitor to discuss alternative 
dosing frequencies.  Patients requiring >2 dose reductions of these drugs will be discontinued 
from the study drug and chemotherapy.  
Brief treatment or visit delays (±7 days) for public holidays or weather conditions do not 
constitute a protocol violation but should be recorded in the eCRF.

Dose modifications due to haematologic toxicity
Complete blood counts (CBC) will be obtained for all patients at the beginning of each 
treatment week and reviewed prior to dose administration.  If hematologic toxicity occurs (see
Table 20), treatment should be held and ANC and platelets should be monitored at least 
weekly.  Patients should be managed as medically indicated.
Treatment should not be resumed until recovery to Grade 1 (ANC ≥1.5 x 109/L or 1,500/μL; 
platelets ≥75,000/μL).

Please consider using G-CSF in the event of severe neutropenia or febrile neutropenia 
according to institutional standards.
No more than two dose reductions will be allowed for any patient.  Patients requiring further 
dose reduction due to toxicity must discontinue study treatment.  Dose re-escalation is not 
allowed.  If the patient has concurrent neutropenia and thrombocytopenia, please follow the 
most conservative guidance in Table 20 and discuss with the MM as needed.
If haematologic parameters do not recover within 28 days, the patient should be removed from 
the study treatment.
6.9.2
Non-haematologic toxicity dose modifications
Substantial acute toxicities should be managed as medically indicated and with temporary 
suspension of investigational product, as appropriate.  Dose reductions or holds and initiation 
of supportive care are allowed as clinically indicated by the treating physician.
Dose reductions of AZD1775 should be considered if the toxicity is considered to be related to 
AZD1775 (i.e. in monotherapy studies or in combination studies) if the relationship cannot be 
wholly attributed to the combination agent (each combination agent should be considered on 
an individual basis). Dose re-escalation is not permitted.

In general, if a patient experiences a Grade 1/Grade 2 non-haematological toxicity, no dose 
modification is required (except QTc prolongation; see table below).  If a patient experiences 
a Grade 3 or Grade 4 toxicity which is not attributable to the disease or disease-related 
processes under investigation, dosing will be interrupted and/or the dose reduced, and 
supportive therapy administered as required.  Any patient who develops a Grade 3 or 4 
non-haematologic toxicity (during the lead-in safety and efficacy portion after completing 
Cycle 1) that does not resolve to ≤ Grade 1 within 21 days should be removed from the study 
treatment, unless approved by the Medical Monitor.  However, if the Investigator determines 
that the non-haematologic toxicity was due to one study drug and not the other, treatment with 
the remaining study drug may continue as clinically appropriate.

6.9.3
Non-haematologic toxicity management guidelines
6.9.3.1
Diarrhoea
Due to frequent reports of diarrhoea with AZD1775 administration, vigorous anti-diarrhoeal 
treatment loperamide (lmodium) is required at the first onset of diarrhoea according to 
American Society of Clinical Oncology (ASCO) guidelines.  Patients should be instructed to 
take oral loperamide (Imodium) 4 mg at the first onset of diarrhoea and then 2 mg every 2 
hours until diarrhoea-free for at least 12 hours. The first dose of loperamide could be lowered 
to 2 mg if the diarrhoea is recurrent and if, in the opinion of the treating physician, the 
diarrhoea is not severe.
Patients should be instructed to notify the Investigator or research staff of the occurrence of 
bloody or black stools, symptoms of dehydration, fever, inability to take liquids by mouth, and 
inability to control diarrhoea within 24 hours of using loperamide (Imodium) or other 
prescribed anti-diarrhoeal medications.
If diarrhoea is severe (i.e., requiring IV rehydration) and/or associated with fever or severe 
neutropenia (Grade 3 or 4), broad-spectrum antibiotics must be prescribed.  Patient with 
severe diarrhoea or any diarrhoea associated with severe nausea or vomiting should be 
hospitalized for IV hydration and correction of electrolyte imbalances.
6.9.3.2
Nausea and vomiting
All patients receiving oral AZD1775 are required to receive premedication for preventing 
nausea and vomiting prior to each AZD1775 dose regardless of the protocol schedule or dose. 
The regimen described below should be instituted immediately for these symptoms:
!
All patients must receive a 5-HT3 antagonist, e.g., ondansetron (Zofran) 8 mg PO BID or 
granisetron (Kytril) 1 mg PO BID prior to each dose of AZD1775.  Additional doses of 5-
HT3 antagonist may be used if needed.  In addition, dexamethasone 4 mg PO will be 
given as a minimum with each AZD1775 dose, on the first day of every 3-5 day dosing

period, unless contraindicated or not well tolerated.   Dexamethasone may be continued 
on further days of dosing, potentially at a lower dose.  Dexamethasone or the 5-HT3 
antagonist may be given by IV, as needed.
!
Aprepitant (Emend) and fosaprepitant are not permitted due to known drug-drug 
interactions.
!
Promethazine (Phenergan], prochlorperazine (Compazine), and benzodiazepine may still 
be used as additional adjunctive treatments during AZD1775 therapy.
!
Patients should be strongly encouraged to maintain liberal oral fluid intake.
!
Suitable alternative medications may be used, with adequate justification, in those studies 
where the use of any of the above medications might interfere with other study 
procedures or are deemed insufficient.
6.9.3.3
Febrile neutropenia
Patients experiencing febrile neutropenia with significant symptoms should be managed in a 
hospital setting according to standard procedures, with the urgent initiation of IV antibiotic 
therapy.  Patients with febrile neutropenia without symptoms should be managed according to 
standard guidelines.
6.9.3.4
Motor neuropathy or muscle weakness
Any onset of > Grade 2 motor neuropathy or > Grade 2 muscle weakness should be evaluated 
by an electromyogram to rule out the possibility of chronic inflammatory demyelinating 
polyneuropathy (CIDP).  With a diagnosis of CIDP the patient should be discontinued from 
study treatment.
6.9.3.5
Dose modifications for infusion reactions
Infusion reactions (e.g. rash, urticaria, erythema, pruritus, bronchospasm, and hypotension) 
can occur with the agents used in this study.  There is increased risk of a reaction with 
carboplatin, paclitaxel and PLD.  Carboplatin and PLD must be discontinued in patients 
experiencing a Grade 3 or 4 infusion reaction during treatment.
To identify the grade of a reaction, refer to the list below adapted for the General Disorders 
and Administration Site Conditions section of the NCI CTCAE v4.03:
Grade 1: Mild transient reaction; infusion interruption not indicated; intervention not 
indicated.
Grade 2: Therapy or infusion interruption indicated but responds promptly to symptomatic 
treatment (e.g., antihistamines, non-steroidal anti-inflammatory drugs [NSAIDs], 
narcotics, IV fluids indicated for ≤24 hours).
Grade 3: Prolonged (e.g., not rapidly responsive to symptomatic mediation and/or brief 
interruption of infusion); recurrence of symptoms following initial improvement;

hospitalization indicated for other clinical sequelae.  Note: any infusion that is 
interrupted and not resumed within the visit will be considered a Grade 3 reaction.
Grade 4: Life-threatening consequences; urgent intervention indicated.
6.10
Study governance and oversight
A Safety Review Team (SRT) will be established by Innovations for this study.  Reviewers 
may include the study PI, MM, Principal Biostatistician, Safety Director, Safety Lead, Clinical 
Data Analyst, Clinical Project Manager, and Sponsor representatives.  The roles and 
responsibilities of the SRT and the MM are described in the Dose Escalation Plan.  
The SRT will review all available safety data on the first 6 evaluable lead-in safety patients 
completing Cycle 1 DLT evaluation from each Part 1 treatment arm.  The SRT will review the 
frequency and severity of AEs of the 6 lead-in safety patients and will compare to published 
data for similar regimens administered in this setting.  The frequency of additional safety 
reviews will be determined by the SRT based on the early safety reviews.  Accrual will not be 
halted while the review is being conducted unless 2 patients experience a DLT in a treatment 
arm.  If safety signals arise from this review, the SRT may recommend discontinuation of 
enrolment to a treatment arm or a change to the dose and/or schedule of AZD1775.  If fewer 
than 2 of the 6 evaluable patients experience a DLT in a treatment arm then enrolment to that 
arm will continue for evaluation of efficacy. 
The MM will monitor the safety of individual patients during the entire AE reporting period 
(i.e., from the first administration of AZD1775 through 30 days after completion of study 
treatment).  In addition, the MM will conduct the safety review to preserve the integrity of the 
study.  MM duties may include, but not limited to the following:
!
Perform periodic reviews of all safety data for individual patients.  These listings will 
include: demographic characteristics, general medical history (including concurrent 
illnesses), disease history, clinical laboratory data (serum chemistry, haematology), any 
AEs requiring study drug interruption or discontinuation, and AEs (all grades).
!
Perform continued monitoring of Grade 3 and higher adverse events and SAEs on an 
ongoing basis for all patients.
Please refer to the Dose Escalation Plan for additional details.

Dose and treatment regimens
7.2.1
AZD1775  
AZD1775 will be taken with 8 ounces of water, approximately 2 hours before or 2 hours after 
food.  The administration schedules for AZD1775 and chemotherapy will differ in the arms.    
If a patient missed a dose according to schedule, the dose should be taken as soon as possible, 
but not more than 6 hours after the missed dose was scheduled.  If greater than 6 hours, the 
missed dose should be skipped and the patient should take the next dose when scheduled.  If 
the patient missed the 5th dose of the cycle (single dose taken on Day 3 of dosing), the dose 
should be taken as soon as possible. 
If vomiting occurs after the patient takes the AZD1775, the patient should be instructed not to 
retake the dose, but to wait until the next scheduled dose of AZD1775.  If vomiting persists, 
the patient should contact the Investigator.  
AZD1775 dosing compliance should be reviewed with the patient at the beginning of each 
new treatment cycle when study drug is dispensed.  All patients will be required to complete a 
Dosing Diary, which must be returned to the clinic for review at each visit.  The patient should 
be instructed to record each date and time the dose(s) were taken on the dosing diary.  If a 
dose is missed, the reason must be noted in the diary.  A copy of the Dosing Diary is provided 
in the study reference materials.  In addition, patients should be advised to return any unused 
AZD1775 in the original bottles, in addition to returning any empty bottles.
All study drugs must be kept in a secure place under appropriate storage conditions.  The IP 
label on the bottle and the IB specifies the appropriate storage.

Chemotherapy
7.2.2.1
Gemcitabine 
800 mg/m2 IV Days 1, 8 and 15 every 28 days
Commercially available gemcitabine 800 mg/m2 IV will be infused over approximately 
30 minutes or according to institutional standards.  
Refer to the gemcitabine package insert for additional information.

7.2.2.2
Paclitaxel 
80 mg/m2 IV Days 1, 8 and 15 every 28 days
Commercially available paclitaxel will be administered as a 1-hour IV infusion (± 10 minutes) 
at a dose of 80 mg/m2 according to institutional standards.  
Patients should be pre-medicated with corticosteroids, diphenhydramine and/or H2 antagonists 
according to institutional standards (see Section 7.7).  
Refer to the paclitaxel package insert for additional information.
7.2.2.3
Carboplatin  
Area Under the Curve (AUC) 5 IV Day 1 every 21 days
Carboplatin, at a dose calculated to produce an AUC of 5 will be administered by intravenous 
infusion according to institutional standards.  
The carboplatin dose will be calculated using the Calvert Formula based on the patient’s GFR 
which is estimated by using the CrCl.  
Calvert Formula: Carboplatin dose (mg) = target AUC x (GFR + 25)
The FDA has recommended that physicians consider capping the dose of carboplatin for the 
desired exposure (AUC) to avoid potential toxicity due to overdosing for all laboratories using 
the IDMS-derived serum creatinine measurements.  Therefore the maximum dose of 
carboplatin should be based on a CrCl no greater than 125 mL/min for patients with normal 
renal function.  In these, carboplatin can be safely dosed according to the instructions in the 
drug’s labelling.  
Refer to US FDA, Center for Drug Evaluation and Research website:  
http://www.fda.gov/AboutFDA/CentersOffices/OfficeofMedicalProductsandTobacco/CDER/

Patients may receive prophylactic anti-emetic therapy for moderately emetogenic 
chemotherapy according to institutional standards, excluding aprepitant (Emend), (see 
Section 7.7).

Pegylated liposomal doxorubicin (PLD)  
Commercially available PLD (40 mg/m2) will be administered on Day 1 of each 28-day Cycle.  
PLD should be administered at an initial rate of 1 mg/min to minimize the risk of infusion 
reactions.  If no infusion related reactions occur, the rate of infusion can be increased to 
complete administration over 1 hour.  A bolus injection or undiluted solution should not be 
administered.  PLD should not be mixed with any other drug.
Refer to the package insert for additional information.
7.2.3
Lead-in safety and efficacy selection
A lead-in safety and efficacy phase will be implemented to establish safety and tolerability 
and to thereafter evaluate efficacy.  
AZD1775 schedules and paired chemotherapeutic agents are presented below:  
Arm A (AZD1775 plus gemcitabine):
AZD1775 (175 mg PO) will be taken once a day on Days 1-2, 8-9 and 15-16.  Gemcitabine 
800 mg/m2 will be administered by intravenous infusion according to institutional standards 
on Days 1, 8, and 15 of each 28 day cycle.  AZD1775 should be taken approximately 2 hours 
before or 2 hours after food.
Arm B (AZD1775 plus weekly paclitaxel):
Five doses of AZD1775 (225 mg PO BID) will be taken in approximate 12 hour intervals over 
2.5 days weekly (Days 1-3, 8-10 and 15-17).  Weekly paclitaxel 80 mg/m2 IV will be 
administered according to institutional standards on Days 1, 8 and 15 of each 28 day cycle.  
AZD1775 should be taken approximately 2 hours before or 2 hours after food.
Arm C (AZD1775 plus carboplatin):
Five doses of AZD1775 (225 mg PO BID) will be taken in approximate 12 hour intervals over 
2.5 days (Days 1-3). AZD1775 should be taken approximately 2 hours before or 2 hours after 
food. Carboplatin AUC 5 IV will be administered according to institutional standards on Day 
1 of each 21 day cycle.  
Arm C2 Safety Expansion
Patients will receive carboplatin AUC 5 IV on Day 1 of a 21 day cycle in combination with 
AZD1775 BID for 2.5 days per dosing week (QW), on Weeks 1 (D1-3), 2 (D8-10) and 3 
(D15-17), or on Weeks 1 (D1-3) and 2 (D8-10) (2 weeks on followed by 1 week off).  
Initially, 6 patients will be enrolled in a 3-weekly AZD1775 dosing cycle; if 1 patient or less 
experiences a DLT during Cycle 1, then an additional 6 patients will be enrolled for a total of 

Clinical Study Protocol
AstraZeneca
AZD1775 - D6010C00004
Version 10, 05 September 2018
CONFIDENTIAL AND PROPRIETARY
99 of 153
12 patients.  However, if 2 or more of the first 6 patients experience a DLT then the AZD1775 
dosing may be modified to 2 weeks on followed by 1 week off.  
All decisions which include but are not limited to cohort dosing, dose escalation or de-
escalation will be reviewed by the Safety Review Team (SRT).
Arm D (AZD1775 plus PLD):
Two dose levels of AZD1775 will be tested with 40 mg/m2 PLD.  The starting dose of 
AZD1775 of this combination arm will be 175 mg, which will be escalated to 225 mg, if the 
lower dose is tolerated.
Five doses of AZD1775 (175 mg or 225 mg) will be taken in approximate 12 hour intervals 
over 2.5 days on week 1 (Days 1, 2 and 3) of each 28-day cycle.  PLD will be administered on 
Day 1 of each cycle.
Alternative dose levels/cohorts and dosing schedules which may be informed by emerging 
pre-clinical and clinical data, including the tolerability data, may be evaluated before the 
MTD/RP2 dose is defined.  Modified PK assessments would be obtained to harmonize and 
accommodate the investigation of alternative dose levels and/or schedules.
7.2.3.1
Arms A, B, & C - First 6 patients and Arm D-First 12 patients
An SRT will assess the safety and tolerability of the first 6 patients in each arm by incidence 
and severity of AEs after a minimum of 1 treatment cycle as determined by NCI CTCAE 
v4.03 and the occurrence of pre-defined dose-limiting toxicities (DLTs).  Patients must 
complete Cycle 1 safety evaluations, and return to the study centre for Cycle 2 Day 1 
evaluations to be considered evaluable for the 6 patient lead-in safety cohort unless a DLT 
occurs prior to completion of Cycle 1.  The responsibilities and general procedures of the SRC 
are described in Section 6.10.
Lead-in safety patients will be considered non-evaluable (NE) and will be replaced if:
!
They are enrolled, but not treated with study drug(s)
!
They discontinue from the study prior to completing all safety evaluations without 
experiencing a DLT during Cycle 1
Non-evaluable patients will not be counted toward the lead-in safety cohort for total DLT 
evaluation.
Patients may continue on study as long as they are benefiting, have no evidence of disease 
progression, and do not meet any criteria for discontinuation or withdrawal.

7.2.4
Definition of dose-limiting toxicity (DLT)
Toxicity will be assessed utilizing the NCI CTCAE v4.03 
(http://evs.nci.nih.gov/ftp1/CTCAE/CTCAE), unless otherwise specified.  
Dose limiting toxicities thought to be related to the study drug during the lead-in safety phase 
will be defined as any of the following toxicities not attributable to the disease or disease-
related processes under investigation, which occur from the first dose of study treatment up to 
the last day of Cycle 1 (first 28 days [Arm A, Arm B and Arm D] or first 21 days [Arm C]), 
and that meets at least 1 of the hematologic or non-hematologic criteria below: 
!
Grade 4 haematological toxicity present for more than 7 days including:  
!
Infection with febrile neutropenia
!
Grade 3 thrombocytopenia associated with haemorrhage
!
Non-haematological toxicity ≥ Grade 3 
!
Any other toxicity that is clinically significant and/or unacceptable, does not respond to 
supportive care, results in a disruption of dosing schedule of more than 7 days, or is 
judged to be a DLT by the Investigator in collaboration with the MM.  
A DLT excludes:
!
Alopecia of any grade
!
Isolated laboratory changes of any grade without clinical sequelae or clinical significance
If appropriate the DLT observation period can be expanded by up to 2 weeks in case of 
treatment delay due to study drug-related AEs.  A treatment combination will be considered 
non-tolerated if 2 or more of up to 6 evaluable patients experience a DLT in the lead-in safety 
cohort.  If the initial dose or schedule of the treatment combination is not tolerated, patient 
enrolment to the treatment combination will be stopped and either the combination will be 
taken no further or the dose level or schedule of AZD1775 may be adjusted to evaluate safety 
in a second 6 patient cohort at the next lower dose level or revised schedule.  The DLT 
criterion applies to only the lead-in safety patients during Cycle 1.  Lead-in safety patients 
continuing treatment beyond Cycle 1 will have dose modifications applied according to 
Section 6.8.  
If fewer than 2 out of 6 patients experience a DLT in a treatment arm then enrolment may
continue for evaluation of efficacy.  
7.2.4.1
Reporting a DLT 
Any DLT occurring in a patient in the lead-in safety cohort during Cycle 1 must be reported to 
the MM by the Investigator or designee within 24 hours of first knowledge, and to the 
Innovations Safety Department as an SAE when appropriate (see Section 6.5).

7.2.5
Evaluation of Efficacy 
Once the AZD1775 plus carboplatin arm is evaluated as safe and tolerated by the SRT, this 
arm will continue enrolling until 23 patients have been evaluated for efficacy (i.e., tumour 
response).  At least 5 of the 23 patients must achieve an objective tumour response according 
to RECIST v1.1 for the treatment arm to be considered as sufficiently efficacious.
The AZD1775 plus paclitaxel arm will enrol approximately 30 additional patients. For 
decision making, ORR will be considered in addition to the observed safety and tolerability 
data and the other efficacy endpoints.
If there are tolerability challenges with the delivery of the initial planned treatment in this 
particular arm, revised dose levels or schedules of AZD1775 and/or the chemotherapy agent 
may be considered.  Such revisions will be documented and communicated in writing to the 
Investigator and the Institutional Review Board (IRB).
7.2.6
Restaging during treatment 
Tumour assessments will be performed at Screening (within 28 days of first dose) as outlined 
in the Study Plan and then every 2 cycles (6 weeks [±7 days] or 8 weeks [±7 days]) depending 
upon the treatment arm, for the first 12 months and every 3 cycles (9 weeks or 12 weeks)
thereafter until objective disease progression as defined by RECIST v1.1.  
Patients will be eligible to continue treatment as long as they are benefiting, have no evidence 
of disease progression, and do not meet any criteria for discontinuation or withdrawal. 
7.2.7
End of study treatment visit
Patients are allowed to continue treatment until disease progression, until the patient is 
discontinued due to unacceptable toxicity, or until a decision to discontinue treatment by the

Medications including but not limited to the 
following:
•
Bisphosphonates and receptor activator of 
nuclear factor kappa-B ligand (RANKL) 
inhibitors (e.g. denosumab).
•
Patients requiring therapeutic warfarin or 
coumadin-derivative anticoagulants will be 
monitored with INR and Prothrombin Time 
(PT) as clinically indicated.
•
Low molecular weight heparin, rivaroxaban, 
or equivalent anticoagulant therapy is 
permitted where clinically indicated.
•
Patients may receive treatment with megestrol 
acetate when prescribed for appetite 
stimulation.
Medications may be administered for maintenance of 
existing conditions prior to study enrolment or for a new 
condition that develops while on study.
Prophylactic hematopoietic growth factors
Hematopoietic growth factors may be used to treat 
neutropenia as indicated by the current American Society 
of Clinical Oncology (ASCO) or Institutional guidelines, 
but should not be used as a substitute for the appropriate 
dose reductions/delays as specified in Section 6.8.   
7.7.2
Restricted concomitant medications
The following treatments and the medications listed below, as listed in Appendix G, should be 
used with caution while in this study.  Any further questions regarding concomitant treatments 
should be referred to the MM.
Restricted Medication/Class of drug:
Usage:
In vitro data suggests that AZD1775 may also be a 
weak reversible inhibitor of CYP2C19.
Caution should be exercised with concomitant 
administration of AZD1775 and agents that are sensitive 
substrates of CYP2C19, or substrates of this enzyme with 
narrow therapeutic range.
Refer to Appendix G for a list of sensitive substrates of 
CYP2C19, or substrates of this enzyme with narrow 
therapeutic range
AZD1775 has been shown to be a weak inducer of 
CYP1A2 in vitro with a maximum measured 
response between donors of 39.9% to 93.1% (at 10 
μM) and 18.6% to 32.5% (at 5 μM) of the positive 
control omeprazole (50 μM), respectively.  Given 
the nature of the AZD1775 dosing schedule, 
however, the risk of induction in the clinic is 
considered low.  
Be initially vigilant when using substrates of CYP1A2 with 
a narrow therapeutic range.

Version 10, 05 September 2018
CONFIDENTIAL AND PROPRIETARY
104 of 153
Restricted Medication/Class of drug:
Usage:
Inhibitors or substrates of P-gp.  
In vitro studies have shown that AZD1775 may be a 
substrate and inhibitor for human P-glycoprotein (P-gp).
Caution should be exercised when agents that are inhibitors 
or substrates of P-gp are administered concomitantly with 
AZD1775 (see Appendix G).
Aminoglycosides
Caution must be exercised with the concomitant use of 
aminoglycosides in keeping with the treatment guidelines 
for carboplatin.
Gemfibrozil and Rifampin
Caution must be exercised with the concomitant use of 
Gemfibrozil (strong CYP2C8 inhibitor) and Rifampin
(strong CYP2C8 inducer) for patients receiving paclitaxel 
in this study.
BCRP substrates with narrow therapeutic index
Recent in vitro transporter studies have shown AZD1775 
to be an inhibitor of BCRP (IC50 5.1 μM).  This finding is 
particularly relevant for drugs administered orally where 
exposure is normally limited by BCRP-mediated efflux, in 
particular some statins, such as rosuvastatin. Other drugs 
where the disposition is mediated via BCRP should be 
administered with caution, dose modification considered, 
or substituted by an alternative drug.
Metformin
AZD1775 has been shown to be an inhibitor of MATE1 
and MATE2K transporters.  A drug interaction with 
substrates of either transporter cannot be ruled out, the 
most important substrate known to date being metformin.
7.7.3
Prohibited concomitant medications
Prohibited Medication/Class of drug:
Additional Information
Anticancer agents other than the study medications
If such agents are required for a patient, then the patient 
must first be withdrawn from the study treatment.
Monoclonal antibodies against PD-1, PD-L1, and 
PD-L2, CXCR2 inhibitors, and therapeutic 
anticancer vaccines
May not be administered through 90 days after the last 
dose of study drug.

Prohibited Medication/Class of drug:
Additional Information
Concomitant treatment with aprepitant and 
fosaprepitant is not allowable per protocol until 
further evaluation.
Potent or moderate inhibitors or inducers of 
CYP3A4, sensitive CYP3A4 substrates, and 
CYP3A4 substrates with a narrow therapeutic 
window should be avoided until additional data on 
drug-drug interaction becomes available.  See 
Appendix G for a list.
No formal clinical drug interaction studies have been 
performed with AZD1775.  An exploratory assessment of 
the effect of aprepitant on AZD1775 exposure in oncology 
patients suggests that there is a drug interaction between 
AZD1775 and aprepitant, as exposure to AZD1775 
increased by ~60% when aprepitant was co-administered 
with AZD1775.  The observed increase in AZD1775 
exposure is likely the result of CYP3A4 inhibition by 
aprepitant.  This increase in exposure is statistically 
significant.  At the selected MTDs, this increase may also 
be of clinical importance.  
Grapefruit, Seville oranges and their products (e.g., 
juice, marmalade, etc.)
As grapefruit and Seville oranges are known to contain 
moderate inhibitors of CYP3A4, these fruits or their 
products (including marmalade, juice, etc.) should be 
avoided while taking AZD1775.
Herbal preparations/medications are not allowed 
throughout the study.  These herbal medications 
include, but are not limited to:  St. John’s wort, 
kava, ephedra (ma huang), gingko biloba, 
dehydroepiandrosterone (DHEA), yohimbe, saw 
palmetto, and ginseng.  
Patients should stop using these herbal medications 7 days 
prior to first dose of AZD1775.
Administration of substances known to prolong 
ECG QTc
The potential risk of concomitant use of AZD1775 with 
ondansetron (known to prolong the QTc interval) should be 
taken into account.
7.7.4
Palliative radiotherapy
Patients may receive palliative radiotherapy during the trial only for local pain control, and 
only if in the opinion of the treating Investigator the patient does not have progressive disease 
(PD).  The radiation field cannot encompass a TL.  Radiation to a TL is considered PD and the 
patient should be removed from study treatment.
7.7.5
Other concomitant treatment
Medication other than that described above, which is considered necessary for the subject’s 
safety and well-being, may be given at the discretion of the Investigator and recorded in the 
appropriate sections of the eCRF.

STATISTICAL ANALYSES BY ASTRAZENECA
8.1
Statistical considerations
A comprehensive description of the statistical analyses and related activities for this study will 
be documented in a statistical analysis plan (SAP) which will be finalized prior to DBL.  Note 
that data will be presented separately from the two parts of the study.
8.2
Sample size estimate
Sample size calculations for Arm C of the study are based upon testing a primary endpoint of 
ORR according to RECIST v1.1. In order to test the null hypothesis of an ORR of 10% 
versus an alternative hypothesis with an ORR of 30%, 23 patients are required in order to have 
85% power to test the null hypothesis using a one-sided exact binomial test at the 0.10 
significance level.  The null hypothesis will be rejected if at least 5 responses are observed 
from 23 patients.
The Part C2 expansion will enrol approximately 12 patients to assess a weekly AZD1775 
dosing regimen in combination with carboplatin in a 3 week cycle. Initially, 6 patients will be 
enrolled in a 3-weekly AZD1775 dosing cycle; if 1 patient or less experiences a DLT during 
Cycle 1, then an additional 6 patients will be enrolled for a total of 12 patients.  However, if 2 
or more of the first 6 patients experience a DLT then the AZD1775 dosing schedule will be 
shortened to 2 weeks on and 1 week off. .  
The AZD1775 plus paclitaxel arm (Arm B) will enrol approximately 30 additional patients.  
Historical response rates using weekly paclitaxel in platinum-resistant and refractory ovarian 
cancer are in the region of 20% to 40% (Pignata et al 2015, Lortholary et al 2011, McNeish et 
al 2014).  The following examples give an indication of the level of precision that will be 
achieved in the paclitaxel treated patients.
If the observed response rate is 30% (9/30), the 2-sided 80% confidence interval (CI) will be 
(19%, 43%).  If the observed response rate is 50% (15/30), the 2-sided 80% CI will be (37%, 
63%).  For decision making, ORR will be considered in addition to the observed safety and 
tolerability data and the other efficacy endpoints.
8.3
Definitions of analysis sets
8.3.1
All patients set
The All Patients Set will include all patients who have signed the informed consent form (i.e. 
screening failures plus patients enrolled).  The All Patients Set will be used to describe the 
patient disposition.

8.3.2
Full analysis set
The Full Analysis Set (FAS) will include all patients who received at least one (non-zero) 
dose of study treatment.  Information using this population will be tabulated by treatment arm 
unless otherwise indicated.  This population will be used for the primary analyses of the 
efficacy and safety endpoints.
8.3.3
PK analysis set
Pharmacokinetics will be summarised as per the PK analysis set.
The PK analysis set will include all dosed patients who had at least one measurable plasma 
concentration collected post-dose which was obtained without any protocol deviation, 
violation, or events thought to significantly affect the PK.
All plasma concentration data for AZD1775, paclitaxel, carboplatin, gemcitabine and PLD, 
and derived PK parameters will be summarised and presented according to AstraZeneca 
standards.  This will be described in the SAP.
8.3.4
CA-125 analysis set
The CA-125 Analysis Set will consist of all dosed patients with a pre-treatment serum sample 
showing CA-125 ≥ 2 x ULN within 2 weeks before starting treatment.  The CA-125 Analysis 
Set will be used to evaluate response according to GCIG CA-125 response criteria.
8.4
Outcome measures for analyses
8.4.1
Calculation or derivation of efficacy variable(s)
8.4.1.1
Tumour response rate
Patients will undergo regular tumour assessments until documented objective disease 
progression as defined by RECIST v1.1 (Eisenhauer et al 2009). At each restaging visit the 
RECIST data for a patient will be assigned a response of CR, PR, SD, or PD depending on the 
status of the disease compared with baseline and previous assessments (see Appendix D).  
The objective response rate (ORR) is defined as the number of the patients with a confirmed 
best overall response of CR or PR divided by the number of patients in the FAS for whom 
measureable disease is present at baseline.  Similarly, the disease control rate (DCR) is 
defined as the percentage of FAS patients with a best overall response of CR, PR or SD. 
Progression of TLs will be calculated in comparison with what the tumour burden was at a 
minimum (i.e., smallest sum of diameters previously recorded on study).  In the absence of 
progression, tumour response (CR, PR, or SD) will be calculated in comparison to the baseline 
tumour measurements obtained before starting treatment.

Version 10, 05 September 2018
CONFIDENTIAL AND PROPRIETARY
108 of 153
If a patient has had a tumour assessment that cannot be evaluated, then the patient will be 
assigned a visit response of NE (unless there is evidence of progression in which case the 
response will be assigned as PD).
For TL measurements, if ≤1/3 of the TL sizes are missing (either NE or not read, or the scan 
was not done) then a scaling up rule will be applied as follows:
!
If ≤1/3 of lesions recorded at baseline are missing, then the results will be scaled up 
(based on the nadir sizes) to give an estimated sum of diameters and this will be used in 
calculations (this is equivalent to comparing the visit sum of diameters of the non-missing 
lesions to the nadir sum of diameters excluding the lesions that are missing and 
determining at what rate the lesions are changing) 
!
If >1/3 of lesions recorded at baseline are missing, then the TL response will be NE.  
However, if the sum of non-missing TL diameters would result in PD (i.e., if using a 
value of 0 for missing lesions the sum of diameters has still increased by >20% or more 
compared with the smallest sum of diameters on study and has an absolute increase ≥5 
mm) PD takes precedence over NE.
!
A visit response of CR will not be allowed if any of the TL data are missing.
8.4.1.2
Progression-free survival 
Progression-free survival is defined as the time from first dose until the date of objective 
disease progression or death (by any cause in the absence of progression) regardless of 
whether the patient withdraws from therapy or receives another anti-cancer therapy prior to 
progression.  Patients who have not progressed or died at the time of analysis will be censored 
at the time of the latest date of assessment from their last evaluable RECIST assessment.  
If the patient progresses or dies after two or more missed visits, the patient will be censored at 
the time of the latest evaluable RECIST assessment.  If the patient has no evaluable visits or 
does not have baseline data they will be censored at 0 days unless they die within two visits of 
baseline.  
Progression-free survival will be derived based on scan/assessment dates not visit dates.  If 
RECIST assessments/scans contributing towards a particular visit are performed on different 
dates then the date of progression will be determined based on the earliest of the dates of the 
component that triggered the progression.  With regard to censoring, a patient will be censored 
at the latest of the dates contributing to a particular overall visit assessment. 
8.4.1.3
Overall survival
Overall survival is defined as the time from the date of first dose until death due to any cause.  
Any patient not known to have died at the time of the analysis will be censored based on the 
last recorded date on which the patient was known to be alive.

8.4.1.4
Changes in tumour size
Percent changes in tumour size from baseline will also be determined for patients with 
measurable disease at baseline and is derived at each visit as the % change in the sum of the 
diameters of TLs. % change = [(post baseline TL sum – baseline TL sum) / baseline TL sum] 
*100.
8.4.1.5
Duration of response
Duration of response is defined as the time from the date of first documented response until 
the date of documented progression or any cause death.  In the case where a patient does not 
progress following response, the DoR censoring time will be the same as the PFS censoring 
time.
8.4.2
Calculation or derivation of safety variable(s)
8.4.2.1
Exposure to investigational product
The total time on study treatment, as well as total exposure to study treatment and the amount 
delivered relative to the intended amount will be summarised.  The number of patients with 
pauses and reductions and the dose intensities of AZD1775, gemcitabine, paclitaxel, and 
carboplatin will also be summarised.
8.4.2.2
Adverse events, laboratory changes, vital signs
Safety profiles will be assessed in terms of AEs and laboratory data, vital signs, and ECG data 
that will be collected for all patients.
8.4.2.3
Other significant adverse events (OAE)
During the evaluation of the AE data, the MM will review the list of AEs that were not 
reported as SAEs and other adverse events (OAEs).  Based on the expert’s judgement, 
significant AEs of particular clinical importance may, after consultation with the Medical 
Science Director, be considered OAEs and reported as such in the CSR.  A similar review of 
laboratory/vital signs/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.
8.4.3
Calculation or derivation of pharmacokinetic variables in plasma
Pharmacokinetic analysis of plasma for AZD1775, gemcitabine, paclitaxel, carboplatin and 
PLD concentration data will be performed by Covance on behalf of AstraZeneca.  Real time 
PK analysis will be conducted prior to each cohort, as appropriate.  The actual sampling times 
will be used in the parameter calculations and PK parameters will be derived using standard 
non-compartmental methods.

8.5
Pharmacokinetics/Pharmacodynamic Analysis
The plasma concentration data for AZD1775 may be analysed using a population PK 
approach, which may include exploring the influence of covariates on PK, if the data allows.  
A population PDx approach will be used to investigate the relationship between PK and 
selected primary, secondary and/or exploratory endpoints, where deemed appropriate.  Results 
may be reported separately from the CSR for the main study.  The PK, PDx, 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-PDx methods.  The 
results of any such analyses will be reported separately from the CSR.
8.6
Methods for statistical analyses
A comprehensive description of the statistical analyses and related activities for this study will 
be documented in a statistical analysis plan (SAP) which will be finalized prior to DBL.  
The study will have a primary cut-off date for the CSR (see Section 9.3).  Following the 
primary analysis data cut-off, no further statistical analysis of the data will be conducted.  All 
safety data collected after the primary analysis and up to (and including) the last of the FPVs

After this point, patients may continue to receive study drug as long as they are continuing to 
derive benefit from treatment as judged by the Investigator and do not have disease 
progression or unmanageable drug-related toxicity.  Patients continuing on study drug beyond 
the FPV (see Section 4.4) will continue to be monitored for all SAEs, overdoses and 
pregnancies while receiving AZD1775 ± chemotherapy. SAEs and pregnancy test results will 
be collected for 30 days after the last dose of the investigational products and should be cared 
for according to local clinical practice.  Investigators must report SAEs and pregnancies
directly to the AstraZeneca representative in accordance with Section 6.5, and continue to 
maintain study drug accountability as long as patients are receiving treatment with the study 
drug.  
The Part B efficacy expansion and Part C2 safety expansion will be conducted at selected 
investigator sites.  The study may be terminated at individual centres if the study procedures 
are not being performed according to Good Clinical Practice (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 AZD1775.
9.4
Data management by AstraZeneca or delegate
Data management will be performed by Innovations, according to the Data Management Plan.  
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 WHO Drug Dictionary.  Classification coding will be 
performed by AstraZeneca or Innovations.

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.  The Data Management Plan will also clarify the roles and 
responsibilities of the various functions and personnel involved in the data management 
process
Serious Adverse Event (SAE) Reconciliation
SAE reconciliation reports from eCRF are produced and reconciled with the Patient Safety 
database and/or the investigational site. 
Data Management of genotype data
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 will be 
reported separately from the CSR for the main study.  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.
Data associated with human biological samples
Data associated with biological samples will be transferred from laboratory(ies) internal or 
external to AstraZeneca.
Management of external data
Data Management determines the format of the data to be received from external vendors and 
coordinates the flow of data to an external environment or clinical database (if applicable). 
Data Management will ensure that the data collection tool (e.g., IWRS, etc.) will be tested / 
validated as needed.

ETHICAL AND REGULATORY REQUIREMENTS
10.1
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)/GCP, applicable regulatory requirements and the AstraZeneca policy on Bioethics and 
Human Biological Samples.

10.2
Subject 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.
AstraZeneca will not provide individual genotype results to subjects, any insurance company, 
any employer, their family members, general physician or any other third party, unless 
required to do so by law.
Precautions are taken to preserve confidentiality and prevent genetic data being linked to the 
identity of the subject. In exceptional circumstances, however, certain individuals might see 
both the genetic data and the personal identifiers of a subject. For example, in the case of a 
medical emergency, an AstraZeneca Physician or an Investigator might know a subject’s 
identity and also have access to his or her genetic data. Also Regulatory authorities may 
require access to the relevant files, though the subject’s medical information and the genetic 
files would remain physically separate.
10.3
Ethics and regulatory review
An Ethics Committee (EC) or 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 subjects.  The Investigator will ensure the distribution of these documents 
to the applicable EC, 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 subject into the study. 
The EC/IRB should approve all advertising used to recruit subjects 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 subject into the study, the final study protocol, including the final 
version of the Informed Consent Form, is approved by the national regulatory authority or a 
notification to the national regulatory authority is done, 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 PIs with safety 
updates/reports according to local requirements.

Each PI 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 PI so that he/she can meet these reporting requirements.
10.4
Informed consent
The PI(s) at each centre will:
!
Ensure each subject is given full and adequate oral and written information about the 
nature, purpose, possible risk and benefit of the study
!
Ensure each subject is notified that they are free to discontinue from the study at any time
!
Ensure that each subject is given the opportunity to ask questions and allowed time to 
consider the information provided
!
Ensure each subject provides signed and dated informed consent before conducting any 
procedure specifically for the study
!
Ensure the original, signed Informed Consent Form(s) is/are stored in the Investigator’s 
Study File
!
Ensure a copy of the signed Informed Consent Form is given to the subject
!
Ensure that any incentives for subjects who participate in the study as well as any 
provisions for subjects harmed as a consequence of study participation are described in 
the informed consent form that is approved by an EC.
10.5
Changes to the protocol and informed consent form
Study procedures will not be changed without the mutual agreement of the Medical Science 
Director 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 CSP).
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 PI(s). For distribution to ECs/IRBs see Section 10.3.
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.

Appendix A
Additional Safety Information
Further Guidance on the Definition of a Serious Adverse Event (SAE)
Life threatening
‘Life-threatening’ means that the subject was at immediate risk of death from the AE as it 
occurred or it is suspected that use or continued use of the product would result in the 
subject’s death.  ‘Life-threatening’ does not mean that had an AE occurred in a more severe 
form it might have caused death (eg, hepatitis that resolved without hepatic failure).
Hospitalisation
Outpatient treatment in an emergency room is not in itself a serious AE, although the reasons 
for it may be (eg, bronchospasm, laryngeal oedema).  Hospital admissions and/or surgical 
operations planned before or during a study are not considered AEs if the illness or disease 
existed before the subject was enrolled in the study, provided that it did not deteriorate in an 
unexpected way during the study.
Important medical event or medical intervention
Medical and scientific judgement should be exercised in deciding whether a case is serious in 
situations where important medical events may not be immediately life threatening or result in 
death, hospitalisation, disability or incapacity but may jeopardize the subject or may require 
medical intervention to prevent one or more outcomes listed in the definition of serious.  
These should usually be considered as serious.
Simply stopping the suspect drug does not mean that it is an important medical event; medical 
judgement must be used.
!
Angioedema not severe enough to require intubation but requiring iv hydrocortisone 
treatment
!
Hepatotoxicity caused by paracetamol (acetaminophen) overdose requiring treatment with 
N-acetylcysteine
!
Intensive treatment in an emergency room or at home for allergic bronchospasm
!
Blood dyscrasias (eg, neutropenia or anaemia requiring blood transfusion, etc) or 
convulsions that do not result in hospitalisation
Development of drug dependency or drug abuse
A Guide to Interpreting the Causality Question
When making an assessment of causality consider the following factors when deciding if there 
is a ‘reasonable possibility’ that an AE may have been caused by the drug.
!
Time Course.  Exposure to suspect drug.  Has the subject actually received the suspect 
drug?  Did the AE occur in a reasonable temporal relationship to the administration of the 
suspect drug?

Clinical Study Protocol
AstraZeneca
AZD1775 - D6010C00004
Version 10, 05 September 2018
CONFIDENTIAL AND PROPRIETARY
125 of 153
!
Consistency with known drug profile.  Was the AE consistent with the previous 
knowledge of the suspect drug (pharmacology and toxicology) or drugs of the same 
pharmacological class? Or could the AE be anticipated from its pharmacological 
properties?
!
De-challenge experience.  Did the AE resolve or improve on stopping or reducing the 
dose of the suspect drug?
!
No alternative cause.  The AE cannot be reasonably explained by another aetiology such 
as the underlying disease, other drugs, other host or environmental factors.
!
Re-challenge experience.  Did the AE reoccur if the suspected drug was reintroduced 
after having been stopped? AstraZeneca would not normally recommend or support a re-
challenge.
!
Laboratory tests.  A specific laboratory investigation (if performed) has confirmed the 
relationship.
In difficult cases, other factors could be considered such as:
!
Is this a recognized feature of overdose of the drug?
!
Is there a known mechanism?
Causality of ‘related’ is made if following a review of the relevant data, there is evidence for a 
‘reasonable possibility’ of a causal relationship for the individual case.  The expression 
‘reasonable possibility’ of a causal relationship is meant to convey, in general, that there are 
facts (evidence) or arguments to suggest a causal relationship.
The causality assessment is performed based on the available data including enough 
information to make an informed judgment.  With limited or insufficient information in the 
case, it is likely that the event(s) will be assessed as ‘not related’.
Causal relationship in cases where the disease under study has deteriorated due to lack of 
effect should be classified as no reasonable possibility.

Appendix B
International Airline Transportation Association (IATA) 6.2 
Guidance Document
Labelling and shipment of biohazard samples
International Airline Transportation Association (IATA) classifies biohazardous agents into 3 
categories.  For transport purposes the classification of infectious substances according to risk 
groups was removed from the Dangerous Goods Regulations (DGR) in the 46th edition 
(2005).  Infectious substances are now classified either as Category A, Category B or Exempt.  
There is no direct relationship between Risk Groups and categories A and B.
Category A Infectious Substances are infectious substances in a form that, when exposure to 
it occurs, is capable of causing permanent disability, life-threatening or fatal disease in 
otherwise healthy humans or animals.  Category A pathogens are eg, Ebola, Lassa fever virus:
!
are to be packed and shipped in accordance with IATA Instruction 602.
Category B Infectious Substances are infectious Substances that do not meet the criteria for 
inclusion in Category A.  Category B pathogens are eg, Hepatitis A, B, C, D, and E viruses, 
Human immunodeficiency virus (HIV) types 1 and 2.  They are assigned the following UN 
number and proper shipping name:
!
UN 3373 – Biological Substance, Category B
!
are to be packed in accordance with UN3373 and IATA 650
Exempt - all other materials with minimal risk of containing pathogens
!
Clinical trial samples will fall into Category B or exempt under IATA regulations
!
Clinical trial samples will routinely be packed and transported at ambient temperature in 
IATA 650 compliant packaging 
!
Biological samples transported in dry ice require additional dangerous goods specification 
for the dry-ice content
!
IATA compliant courier and packaging materials should be used for packing and 
transportation and packing should be done by an IATA certified person, as applicable
!
Samples routinely transported by road or rail are subject to local regulations which 
require that they are also packed and transported in a safe and appropriate way to contain 
any risk of infection or contamination by using approved couriers and packaging / 
containment materials at all times.  The IATA 650 biological sample containment 
standards are encouraged wherever possible when road or rail transport is used.

Appendix C
Actions Required in Cases of Increases in Liver Biochemistry 
and Evaluation of Hy’s Law
Introduction
This Appendix describes the process to be followed in order to identify and appropriately 
report cases of Hy’s Law.  It is not intended to be a comprehensive guide to the management 
of elevated liver biochemistries.  
During the course of the study the Investigator will remain vigilant for increases in liver 
biochemistry.  The Investigator is responsible for determining whether a patient meets 
potential Hy’s Law (PHL) criteria at any point during the study.
The Investigator participates, together with AstraZeneca clinical project representatives, in 
review and assessment of cases meeting PHL criteria to agree whether Hy’s Law (HL) criteria 
are met.  HL criteria are met if there is no alternative explanation for the elevations in liver 
biochemistry other than Drug Induced Liver Injury (DILI) caused by the Investigational 
Medicinal Product (IMP). 
The Investigator is responsible for recording data pertaining to PHL/HL cases and for 
reporting Adverse Events (AEs) and Serious Adverse Events (SAEs) according to the 
outcome of the review and assessment in line with standard safety reporting processes.
Definitions
Potential Hy’s Law (PHL)
Aspartate Aminotransferase (AST) or Alanine Aminotransferase (ALT) ≥ 3x Upper Limit of 
Normal (ULN) together with Total Bilirubin (TBL) ≥ 2xULN at any point during the study 
following the start of study medication  irrespective of an increase in Alkaline Phosphatase 
(ALP).
Hy’s Law (HL)
AST or ALT ≥ 3x ULN  together with TBL ≥ 2xULN, where no other reason, other than the 
IMP, can be found to explain the combination of increases, e.g., elevated ALP indicating 
cholestasis, viral hepatitis, another drug.  
For PHL and HL the elevation in transaminases must precede or be coincident with (i.e. on the 
same day) the elevation in TBL, but there is no specified timeframe within which the 
elevations in transaminases and TBL must occur.
Identification of Potential Hy’s Law Cases
In order to identify cases of PHL it is important to perform a comprehensive review of 
laboratory data for any patient who meets any of the following identification criteria in 
isolation or in combination:

When a patient meets any of the identification criteria, in isolation or in combination, the 
central laboratory will immediately send an alert to the Investigator (also sent to AstraZeneca 
representative). 
The Investigator will also remain vigilant for any local laboratory reports where the 
identification criteria are met, where this is the case the Investigator will:
!
Notify the AstraZeneca representative
!
Request a repeat of the test (new blood draw) by the central laboratory
!
Complete the appropriate unscheduled laboratory CRF module(s) with the original local 
laboratory test result
When the identification criteria are met from central or local laboratory results the Investigator 
will without delay:
!
Determine whether the patient meets PHL criteria (see Definitions within this Appendix 
for definition) by reviewing laboratory reports from all previous visits (including both 
central and local laboratory results)
The Investigator will without delay review each new laboratory report and if the identification 
criteria are met will:
!
Notify the AstraZeneca representative
!
Determine whether the patient meets PHL criteria (see Definitions within this Appendix 
for definition) by reviewing laboratory reports from all previous visits
!
Promptly enter the laboratory data into the laboratory CRF
Follow-up
Potential Hy’s Law Criteria not met
If the patient does not meet PHL criteria the Investigator will:
!
Inform the AstraZeneca representative that the patient has not met PHL criteria.
!
Perform follow-up on subsequent laboratory results according to the guidance provided in 
the CSP.
Potential Hy’s Law Criteria met
If the patient does meet PHL criteria the Investigator will:

Notify the AstraZeneca representative who will then inform the central Study Team 
The MM contacts the Investigator, to provide guidance, discuss and agree an approach for the 
study patients’ follow-up and the continuous review of data.  Subsequent to this contact the 
Investigator will:
!
Monitor the patient until liver biochemistry parameters and appropriate clinical symptoms 
and signs return to normal or baseline levels, or as long as medically indicated 
!
Investigate the etiology of the event and perform diagnostic investigations as discussed 
with the MM. This includes deciding which the tests available in the Hy’s law lab kit 
should be used. 
!
Complete the three Liver CRF Modules as information becomes available 
!
If at any time (in consultation with the MM) the PHL case meets serious criteria, report it 
as an SAE using standard reporting procedures
Review and Assessment of Potential Hy’s Law Cases
The instructions in this Section should be followed for all cases where PHL criteria are met.
No later than 3 weeks after the biochemistry abnormality was initially detected, the MM 
contacts the Investigator in order to review available data and agree on whether there is an 
alternative explanation for meeting PHL criteria other than DILI caused by the IMP.  The 
AstraZeneca Medical Science Director and Global Safety Physician will also be involved in 
this review together with other subject matter experts as appropriate.  
According to the outcome of the review and assessment, the Investigator will follow the 
instructions below.
If there is an agreed alternative explanation for the ALT or AST and TBL elevations, a 
determination of whether the alternative explanation is an AE will be made and subsequently 
whether the AE meets the criteria for a SAE:
!
If the alternative explanation is not an AE, record the alternative explanation on the 
appropriate CRF
!
If the alternative explanation is an AE/SAE, record the AE /SAE in the CRF accordingly 
and follow the AZ standard processes
If it is agreed that there is no explanation that would explain the ALT or AST and TBL 
elevations other than the IMP:

If, there is an unavoidable delay, of over 3 weeks, in obtaining the information necessary to 
assess whether or not the case meets the criteria for HL, then it is assumed that there is no 
alternative explanation until such time as an informed decision can be made:

whether HL criteria are met.  Update the SAE report according to the outcome of the 
review
Actions Required When Potential Hy’s Law Criteria are Met Before and After Starting 
Study Treatment 
This section is applicable to patients with liver metastases who meet PHL criteria on study 
treatment having previously met PHL criteria at a study visit prior to starting study treatment.
At the first on study treatment occurrence of PHL criteria being met the Investigator will:
!
Determine if there has been a significant change in the patients’ condition# compared with 
the last visit where PHL criteria were met#
∀
If there is no significant change no action is required
∀
If there is a significant change notify the AstraZeneca representative, who will inform 
the central Study Team, then follow the subsequent process described in  
# A ‘significant’ change in the patient’s condition refers to a clinically relevant change in any 
of the individual liver biochemistry parameters (ALT, AST or total bilirubin) in isolation or in 
combination, or a clinically relevant change in associated symptoms.  The determination of 
whether there has been a significant change will be at the discretion of the Investigator, this 
may be in consultation with the MM if there is any uncertainty.
Actions Required for Repeat Episodes of Potential Hy’s Law

The requirement to conduct follow-up, review and assessment of a repeat occurrence(s) of 
PHL is based on the nature of the alternative cause identified for the previous occurrence.  
The Investigator should determine the cause for the previous occurrence of PHL criteria being 
met and answer the following question:
!
Was the alternative cause for the previous occurrence of PHL criteria being met found to 
be the disease under study e.g. chronic or progressing malignant disease, severe infection 
or liver disease, or did the patient meet PHL criteria prior to starting study treatment and 
at their first on study treatment visit as described in Actions Required When Potential 
Hy’s Law Criteria are Met Before and After Starting Study Treatment?
If No: follow the process described in Potential Hy’s Law Criteria met of this Appendix
If Yes:
Determine if there has been a significant change in the patient’s condition# compared with 
when PHL criteria were previously met
!
If there is no significant change no action is required
!
If there is a significant change follow the process described in Section 4.2 of this 
Appendix

Guidelines for Evaluation of Objective Tumour Response 
Using RECIST 1.1 Criteria (Response Evaluation Criteria in 
Solid Tumours)
INTRODUCTION
This appendix details the implementation of RECIST 1.1 Guidelines (Eisenhauer et al 2009) 
for the D6010C00004 study with regards to Investigator assessment of tumour burden 
including protocol-specific requirements for this study.
Definition of measurable, non-measurable, target and non-target lesions
Patients with measurable and non-measurable disease at baseline should be included in Part A 
of the study.  Only patients with measurable disease at baseline should be included in Part B 
of the study.  Measurable disease is defined by the presence of at least one measurable lesion 
which has not been previously irradiated. 
Measurable:
A lesion, not previously irradiated, that can be accurately measured at baseline as ≥ 10 mm in 
the longest diameter (except lymph nodes which must have short axis ≥ 15 mm) with CT or 
MRI and which is suitable for accurate repeated measurements.
Non-measurable:
!
All other lesions, including small lesions (longest diameter <10 mm or pathological 
lymph nodes with ≥10 to <15mm short axis at baseline*).
!
Truly non-measurable lesions include the following: bone lesions, leptomeningeal 
disease, ascites, pleural / pericardial effusion, inflammatory breast disease, lymphangitic 
involvement of skin or lung, abdominal masses/abdominal organomegaly identified by 
physical examination that is not measurable by CT or MRI.
!
Previously irradiated lesions**
!
Skin lesions assessed by clinical examination***
!
Brain metastasis***
* Nodes with <10mm short axis are considered non-pathological and should not be recorded 
or followed as NTL.
**Localised post-radiation changes which affect lesion sizes may occur.  Therefore, lesions 
that have been previously irradiated will not be considered measurable and must be selected as 
Non-Target Lesions (NTL) at baseline and followed up as part of the NTL assessment.

Special Cases:
!
Lytic bone lesions or mixed lytic–blastic lesions, with identifiable soft tissue components, 
can be considered measurable if the soft tissue component meets the definition of 
measurability. Blastic lesions are considered non-measurable.
!
Cystic metastases can be considered measurable lesions if they meet the criteria for 
measurability from a radiological point of view, but if non-cystic lesions are present in the 
same patient, these should be selected as target lesions (TLs).
Target lesions:
A maximum of 5 measurable lesions (with a maximum of 2 lesions per organ), representative 
of all lesions involved suitable for accurate repeated measurement, should be identified as 
(TLs) at baseline.
Non-Target lesions:
All other lesions (or sites of disease) not recorded as TL should be identified as NTL at 
baseline.
METHODS OF ASSESSMENT
The same method of assessment and the same technique should be used to characterize each 
identified and recorded lesion at baseline and during follow-up visits.
A summary of the methods to be used for RECIST assessment is provided below, and those 
excluded from tumour assessments for this study are highlighted, with the rationale provided.

In the D6010C00004 study it is recommended that CT examinations of the chest, abdomen, 
and pelvis will be used to assess tumour burden at baseline and follow-up visits.  CT 
examination with intravenous (IV) contrast media administration is the preferred method.  
MRI should be used where CT is not feasible or it is medically contra-indicated.  For brain 
lesion assessment, MRI is the preferred method.
Clinical Examination
In the D6010C00004 study, clinical examination will not be used for assessment of TL.  
Clinically detected lesions can be selected as TLs if they are assessed by CT or MRI scans.  
Clinical examination can be used to assess NTL and to identify the presence of new lesions.
Chest x-ray
In the D6010C00004 study, chest x-ray assessment will not be used for assessment of TL as
they will be assessed by CT examination or MRI examination.  Chest X-ray can, however, be 
used to assess NTL and to identify the presence of new lesions.
Plain x-ray
In the D6010C00004 study plain x-ray may be used as a method of assessment for bone NTL
and to identify the presence of new bone lesions. 
Ultrasound
In the D6010C00004 study, ultrasound examination will not be used for assessment of TL and 
NTL as it is not a reproducible method, does not provide an accurate assessment of tumour 
size and it is subjective and operator dependent.  Ultrasound examination can, however, be 
used to identify the presence of new lesions.  If new clinical symptoms occur and an 
ultrasound is performed then new lesions should be confirmed by CT or MRI examination.
Endoscopy and laparoscopy
In the D6010C00004 study, endoscopy and laparoscopy will not be used for tumour
assessments as they are not validated in the context of tumour assessment.
Tumour Markers
In the D6010C00004 study tumour markers will not be used for tumour response assessments 
as per RECIST 1.1.
Cytology and histology
In the D6010C00004 study histology will not be used as part of the tumour response 
assessment as per RECIST 1.1. 
Cytological confirmation of the neoplastic origin of any effusion that appears or worsens 
during treatment is required when the measurable tumour has met criteria for response or SD.

In such circumstances, the cytology is necessary to differentiate between response/SD (an 
effusion may be a side effect of the treatment) and PD (if the neoplastic origin of the fluid is 
confirmed).  Where cytology findings are not available, any effusion that significantly 
worsens (from trace to large) or appearance of clinically significant effusion (requiring change 
in drug therapy) during the study treatment will be considered to be progression of NTL, or 
disease progression due to new lesions. 
Isotopic bone scan
Bone lesions identified on an isotopic bone scan at baseline and confirmed by CT, MRI or X-
ray at baseline should be recorded as NTL and followed by the same method as per baseline 
assessment.  
In the D6010C00004 study isotopic bone scans may be used as a method of assessment to 
identify the presence of new bone lesions at follow-up visits.  New lesions will be recorded 
where a positive hot-spot that was not present on the baseline bone scan assessment is 
identified on a bone scan performed at any time during the study.  The Investigator should 
consider the positive hot-spot to be a significant new site of malignant disease and represent 
true disease progression in order to record the new lesion.  Confirmation by CT, MRI and x-
ray is recommended where bone scan findings are equivocal.
FDG-PET Scans
In the D6010C00004 study fluorodeoxyglucose positron-emission tomography (FDG-PET) 
scans may be used as a method for identifying new lesions, according with the following 
algorithm:  New lesions will be recorded where there is positive FDG uptake* not present on 
baseline FDG-PET scan or in a location corresponding to a new lesion on CT/MRI at the same 
follow-up visit.  If there is no baseline FDG-PET scan available, and no evidence of new 
lesions on CT/MRI scans then follow-up CT/MRI assessments should be continued, scheduled 
as per protocol or clinical indicated, in order to confirm new lesions.
* A positive FDG-PET scan lesion should be reported only when an uptake greater than twice 
that of the surrounding tissue is observed.
TUMOUR RESPONSE EVALUATION
Schedule of evaluation
Baseline assessments should encompass chest, abdomen and pelvis and should additionally 
investigate areas that may be involved based on signs and symptoms of individual patients and 
should be performed no more than 28 days before the start of study treatment.  Follow-up 
assessments will be performed every 2 cycles +/- 1 week window interval after start of 
treatment until objective disease progression as defined by RECIST 1.1 or withdrawal from 
study.  Any other sites at which new disease is suspected should also be adequately imaged at 
follow-up.

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.  This 
schedule is to be followed in order to minimise any unintentional bias caused by some patients 
being assessed at a different frequency than other patients.
Target Lesions (TA)
Documentation of target lesions
A maximum of 5 measurable lesions, with a maximum of 2 lesions per organ (including 
lymph nodes), representative of all lesions involved should be identified as TL at baseline.  
Target lesions should be selected on the basis of their size (longest diameter for non-nodal 
lesions or short axis for nodal lesions), but in addition should be those that lend themselves to 
reproducible repeated measurements.  It may be the case that, on occasion, the largest lesion 
does not lend itself to reproducible measurement in which circumstance the next largest 
lesion, which can be measured reproducibly, should be selected.
The site and location of each TL should be documented as well as the longest diameter for 
non-nodal lesions (or short axis for lymph nodes). All measurements should be recorded in 
millimeters.  At baseline the sum of the diameters for all TL will be calculated and reported as 
the baseline sum of diameters.  At follow-up visits the sum of diameters for all TL will be 
calculated and reported as the follow-up sum of diameters.
Special cases:
!
For TL measurable in 2 or 3 dimensions, always report the longest diameter. For 
pathological lymph nodes measurable in 2 or 3 dimensions, always report the short axis. 
!
If the CT/MRI slice thickness used is > 5mm, the minimum size of measurable disease at 
baseline should be twice the slice thickness of the baseline scan.
!
If a lesion has completely disappeared, the longest diameter should be recorded as 0 mm.
!
If a TL splits into two or more parts, then record the sum of the diameters of those parts. 
!
If two or more TL merge then the sum of the diameters of the combined lesion should be 
recorded for one of the lesions and 0 mm recorded for the other lesion(s).  
!
If a TL is believed to be present and is faintly seen but too small to measure, a default 
value of 5mm should be assigned.  If an accurate measure can be given, this should be 
recorded, even if it is below 5mm.
!
If a TL cannot be measured accurately due to it being too large, provide an estimate of the 
size of the lesion. 
!
When a TL has had any intervention e.g. radiotherapy, embolisation, surgery etc., during 
the study, the size of the TL should still be provided where possible.

Evaluation of target lesions
This section provides the definitions of the criteria used to determine objective tumour visit 
response for TL.
Complete Response (CR)
Disappearance of all TLs since baseline.  Any pathological lymph 
nodes selected as TLs must have a reduction in short axis to < 10 
mm.
Partial Response (PR)
At least a 30% decrease in the sum of the diameters of TL, taking as 
reference the baseline sum of diameters
Stable Disease (SD)
Neither sufficient shrinkage to qualify for PR nor sufficient increase 
to qualify for PD
Progressive Disease (PD)
At least a 20% increase in the sum of diameters of TLs, taking as 
reference the smallest sum on study (this includes the baseline sum if 
that is the smallest on study).  In addition to the relative increase of 
20%, the sum must also demonstrate an absolute increase of at least 
5mm.
Not Evaluable (NE)
Only relevant if any of the TLs were not assessed or not evaluable or 
had a lesion intervention at this visit. Note:  If the sum of diameters 
meets the PD criteria, PD overrides NE as a TL response
Non-Target Lesions
Evaluation of non-target lesions
All other lesions (or sites of disease) not recorded as TL should be identified as NTL at 
baseline.  Measurements are not required for these lesions, but their status should be followed 
at subsequent visits.  At each visit an overall assessment of the NTL response should be 
recorded by the Investigator.  This section provides the definitions of the criteria used to 
determine and record overall response for NTL at the investigational site at each visit.
Evaluation of non-target lesions
Complete Response (CR)
Disappearance of all NTLs since baseline. All lymph nodes must 
be non-pathological in size (< 10 mm short axis).
Non CR/Non PD
Persistence of one or more NTL 
Progression (PD)
Unequivocal progression of existing NTLs.  Unequivocal 
progression may be due to an important progression in one lesion 
only or in several lesions.  In all cases the progression MUST be 
clinically significant for the physician to consider changing (or 
stopping) therapy.

Clinical Study Protocol

AZD1775 - D6010C00004
Version 10, 05 September 2018
CONFIDENTIAL AND PROPRIETARY
138 of 153
Not Evaluable (NE)
Only relevant when one or some of the NTLs were not assessed 
and, in the Investigator's opinion, they are not able to provide an 
evaluable overall NTL assessment at this visit.
Note:  For patients without TLs at baseline, this is relevant if 
any of the NTLs were not assessed at this visit and the 
progression criteria have not been met.
To achieve ‘unequivocal progression’ on the basis of NTLs, there must be an overall level of 
substantial worsening in non-target disease such that, even in presence of SD or PR in TLs, 
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 qualify for 
unequivocal progression status.
New Lesions
Details of any new lesions will also be recorded with the date of assessment.  The presence of 
one or more new lesions is assessed as progression. 
A lesion identified at a follow up assessment in an anatomical location that was not scanned at 
baseline is considered a new lesion and will indicate disease progression.
The finding of a new lesion should be unequivocal: i.e. not attributable to differences in 
scanning technique, change in imaging modality or findings thought to represent something 
other than tumour.
If a new lesion is equivocal, for example because of its small size, the treatment and tumour 
assessments should be continued until the new lesion has been confirmed.  If repeat scans 
confirm there is a new lesion, then the progression date should be declared using the date of 
the initial scan.
Symptomatic Deterioration
Symptomatic deterioration is not a descriptor of an objective response: it is a reason for 
stopping study therapy.
Patients with ‘symptomatic deterioration’ requiring discontinuation of treatment without 
objective evidence of disease progression at that time should continue to undergo tumour 
assessments where possible until objective disease progression is observed.
Evaluation of overall visit response
The overall visit response will be derived using the algorithm shown below.

CONFIRMATION OF RESPONSE
In the D6010C00004 study, imaging for confirmation of response (CR or PR) should be 
performed at next scheduled visit (certainly no less than 4 weeks) following the date the 
criteria for response were first met.
SPECIFICATIONS FOR RADIOLOGICAL IMAGING
These notes are recommendations for use in clinical studies.  The use of standardized 
protocols for CT and MRI allows comparability both within and between different studies, 
irrespective of where the examination has been undertaken.
CT Scans
CT scans of the chest, abdomen, and pelvis should be contiguous throughout all the anatomic 
region of interest.
The most critical CT image acquisition parameters for optimal tumour evaluation using 
RECIST 1.1 are anatomic coverage, contrast administration, slice thickness, and 
reconstruction interval.
Anatomic coverage: Optimal anatomic coverage for most solid tumours is the chest, 
abdomen and pelvis. Coverage should encompass all areas of known predilection for 

Clinical Study Protocol

metastases in the disease under evaluation and should additionally investigate areas that may 
be involved based on signs and symptoms of individual patients.  Because a lesion later 
identified in a body part not scanned at baseline would be considered as a new lesion 
representing disease progression, careful consideration should be given to the extent of 
imaging coverage at baseline and at subsequent follow-up time points.  This will enable better 
consistency not only of tumour measurements but also identification of new disease.
IV contrast administration: Optimal visualisation and measurement of metastases in solid 
tumours requires consistent administration (dose and rate) of IV contrast as well as timing of 
scanning.  Typically, most abdominal imaging is performed during the portal venous phase 
and (optimally) about the same time frame after injection on each examination.  An adequate 
volume of a suitable contrast agent should be given so that the metastases are demonstrated to 
best effect and a consistent method is used on subsequent examinations for any given patient.  
It is very important that the same technique be used at baseline and on follow- up 
examinations for a given patient.  For patients who develop contraindications to contrast after 
baseline contrast CT is done, the decision as to whether non-contrast CT or MRI (enhanced or 
non-enhanced) should be performed should also be based on the tumour type, anatomic 
location of the disease and should be optimised to allow for comparison to the prior studies if 
possible.  Each case should be discussed with the radiologist to determine if substitution of 
these other approaches is possible and, if not, the patient should be considered NE from that 
point forward.  Care must be taken in measurement of TLs on a different modality and 
interpretation of non-target disease or new lesions, since the same lesion may appear to have a 
different size using a new modality.  Oral contrast is recommended to help visualise and 
differentiate structures in the abdomen. 
If iodine contrast media is medically contraindicated at baseline or at any time during the 
course of the study then the recommended methods are:  CT thoracic examination without 
contrast and abdominal and pelvis MRI with contrast.  If MRI cannot be performed then CT 
without IV contrast is an option for the thorax, abdomen and pelvis examination.  For brain 
lesions assessment, MRI is the preferred method. 
Slice thickness and reconstruction interval: It is recommended that CT scans be performed 
at 5mm contiguous slice thickness and this guideline presumes a minimum 5 mm thickness in 
recommendations for measurable lesion definition.  Exceptionally, particular institutions may 
perform medically acceptable scans at slice thicknesses greater than 5 mm.  If this occurs, the 
minimum size of measurable lesions at baseline should be twice the slice thickness of the 
baseline scans.
All window settings should be included in the assessment, particularly in the thorax where 
lung and soft tissue windows should be considered.  When measuring lesions, the TL should 
be measured on the same window setting for repeated examinations throughout the study.  All

images from each examination should be included in the assessment and not “selected” 
images of the apparent lesion.
MRI Scans
MRI has excellent contrast, spatial and temporal resolution; however, there are many image 
acquisition variables involved in MRI, which greatly impact image quality, lesion conspicuity 
and measurement.  Furthermore, the availability of MRI is variable globally.  The modality 
used at follow-up should be the same as was used at baseline and the lesions should be 
measured/assessed on the same pulse sequence.  Generally, axial imaging of the abdomen and 
pelvis with T1 and T2 weighted imaging along with gadolinium-enhanced imaging should be 
performed.  The field of view, matrix, number of excitations, phase encode steps, use of fat 
suppression and fast sequences should be optimised for the specific body part being imaged as 
well as the scanner utilised.  It is beyond the scope appendix to prescribe specific MRI pulse 
sequence parameters for all scanners, body parts and diseases.  Ideally, the same type of 
scanner should be used and the image acquisition protocol should be followed as closely as 
possible to prior scans.  Body scans should be performed with breath-hold scanning 
techniques if possible.
For these reasons, CT is the imaging modality of choice.
FDG-PET Scans
FDG-PET has gained acceptance as a valuable tool for detecting, staging and restaging several 
malignancies.  If  FDG-PET scans are included in a protocol, an FDG uptake period of 60 min 
prior to imaging has been decided as the most appropriate for imaging of  patients with 
malignancy.  Whole-body acquisition is important since this allows for sampling of all areas 
of interest and can assess if new lesions have appeared thus determining the possibility of 
interval progression of disease.  Images from the base of the skull to the level of the mid-thigh 
should be obtained 60 min post injection.  PET camera specifications are variable and 
manufacturer specific, so every attempt should be made to use the same scanner, or the same 
model scanner, for serial scans on the same patient.  Whole-body acquisitions can be 
performed in either 2- or 3-dimensional mode with attenuation correction, but the method 
chosen should be consistent across all patients and serial scans in the clinical trial.
PET/CT Scans
At present, low dose or attenuation correction CT portions of a combined PET–CT are of 
limited use in anatomically based efficacy assessments and it is therefore suggested that they 
should not be substituted for dedicated diagnostic contrast enhanced CT scans for tumour 
measurements by RECIST 1.1.  In exceptional situations, if a site can document that the CT 
performed as part of a PET–CT is of identical diagnostic quality to a diagnostic CT (with IV 
and oral contrast) then the CT portion of the PET–CT can be used for RECIST measurements.

However, this is not recommended because the PET portion of the CT introduces additional 
data that may bias an Investigator if it is not routinely or serially performed.

Definition of Women of Childbearing Potential and 
Acceptable Contraceptive Methods
DEFINITION OF WOMEN OF CHILDBEARING POTENTIAL
Women of Child Bearing Potential (WoCBP) - Women between menarche and menopause 
who have not been permanently or surgically sterilized and are capable of procreation.
Women NOT of Childbearing Potential - Women who are permanently or surgically 
sterilized or postmenopausal (definitions below):
Permanent sterilisation includes hysterectomy and/or bilateral oophorectomy and/or bilateral 
salpingectomy but excludes bilateral tubal occlusion.  Tubal occlusion is considered a highly 
effective method of birth control but does not absolutely exclude possibility of pregnancy.  
(The term occlusion refers to both occluding and ligating techniques that do not physically 
remove the oviducts).
!
Women who have undergone tubal occlusion should be managed on trials as if they are of 
WoCBP (e.g. undergo pregnancy testing etc. as required by the study protocol).
!
Women will be considered postmenopausal if they are amenorrheic for 12 months 
without an alternative medical cause.  The following age-specific requirements apply:
!
Women under 50 years old will be considered postmenopausal if they have been 
amenorrheic for 12 months or more following cessation of exogenous hormonal 
treatments and with LH and FSH levels in the post-menopausal range.
!
Women over 50 years of age will be considered postmenopausal if they have been 
amenorrheic for 12 months or more following cessation of all exogenous hormonal 
treatments.
ACCEPTABLE CONTRACEPTION METHODS
Highly effective method of birth control is defined in Note 3 in ICH Guidance M3 
(Nonclinical Safety Studies for the conduct of Human Clinical trials for Pharmaceuticals) as 
one that results in a low failure rate (e.g. less than 1 percent per year) when used consistently 
and correctly.
The following methods of highly effective contraception are considered acceptable.
Note that women should have been stable on their chosen method of birth control for a 
minimum of 2 weeks before entering the trial.  Generic names and examples of trade names 
are given.  As trade names may vary, Investigators should check the generic name of any 
contraception to ensure suitability.
Acceptable contraception methods are:

!
Total sexual abstinence:  abstinence is only acceptable as ‘total/true abstinence’ when the 
subject refrains from any form of sexual intercourse and this is in line with their usual 
and/or preferred lifestyle; this must continue for the total duration of the trial and for at 
least 1 month after the last dose of AZD1775 for patients who do not receive paclitaxel, 
and for at least 6 months after the last dose of paclitaxel treatment for patients on the 
paclitaxel arm.
!
Vasectomised sexual partner plus male condom (with participant assurance that partner 
received post-vasectomy confirmation of azoospermia)
!
Tubal occlusion plus male condom
!
Intrauterine Device (IUD) - provided coils are copper-banded, plus male condom
!
Intra-uterine system (IUS) Levonorgestrel Intrauterine System (e.g., Mirena), plus male 
condom
!
Medroxyprogesterone injections (Depo-Provera) plus male condom
!
Etonogestrel implants (e.g., Implanon, Norplan) plus male condom
!
Normal and low dose combined oral contraceptive pills, plus male condom
!
Norelgestromin / ethinylestradiol transdermal system plus male condom
!
Intravaginal device (e.g. ethinylestradiol and etonogestrel ) plus male condom
!
Cerazette (desogestrel) plus male condom.  Cerazette is currently the only highly 
efficacious progesterone based pill
UNACCEPTABLE CONTRACEPTION METHODS
The following methods are considered not to be highly effective and are therefore not 
acceptable contraceptive methods in AstraZeneca clinical trials:
!
Triphasic combined oral contraceptives (COCs)
!
All progesterone only pills except, Cerazette
!
All barrier methods, if intended to be used alone
!
Non-copper containing Intrauterine Devices (IUDs)
!
Fertility awareness methods (e.g, calendar, ovulation, symptothermal, post-ovulation 
methods)
!
Coitus interruptus

Disallowed Medications and Medications to be Administered 
with Caution
Formal drug-drug interaction studies have not yet been performed with AZD1775, therefore, 
the potential for drug-drug interaction described in this protocol are based on findings from in 
vitro studies and clinical experience.
In vitro data has shown that AZD1775 is metabolised predominantly by CYP3A4, with an 
FMO3 and/or FMO5 component.  As a result, there is potential for the exposure of AZD1775 
to be affected by drugs which inhibit or induce the metabolism of CYP3A4.  In the clinic, co-
administration of AZD1775 with the moderate CYP3A4 inhibitor, aprepitant, resulted in a 
40% increase in the plasma levels of AZD1775.  Drugs known to be moderate to strong 
inhibitors/inducers of CYP3A4 are therefore prohibited for use in the current study, including 
aprepitant.  
In vitro data suggests that AZD1775 may be a weak reversible inhibitor of CYP2C19 (IC50 12 
μM).  Caution should therefore be exercised when AZD1775 is co-administered with agents 
that are sensitive substrates of CYP2C19, or substrates of this enzyme with a narrow 
therapeutic range.
Based on in vitro studies, AZD1775 has been shown to be a weak reversible inhibitor (IC50 14 
μM) and a time-dependent inhibitor of CYP3A4 (Kinact 0.061/min, Ki 6.04 μM).  The full 
impact of the time dependent inhibition is currently unknown, however, modelling data has 
predicted an 8-10 fold increase in the exposure of sensitive CYP3A4 substrates when 
administered with AZD1775 (250 mg BID for 5 doses).  To date, no significant DDI effects 
have been reported in the clinic that may be related to the TDI finding.  However, sensitive 
CYP3A4 substrates or substrates of CYP3A4 with a narrow therapeutic window are 
prohibited.
AZD1775 has been shown to be a weak inducer of CYP1A2 in vitro (39% increase in activity 
of positive control).  Given the nature of the AZD1775 dosing schedule, however, the risk of 
induction in the clinic is considered low.  No specific precautions are recommended at this 
time, except to be initially vigilant when using substrates of CYP1A2 with a narrow 
therapeutic range.
Transporter studies (in vitro) have shown that AZD1775 is both a substrate and inhibitor (IC50
20 μM) of P-gp.  Maximum impact of these finding is likely to occur for drugs administered 
orally at the same time as AZD1775.  Caution should therefore be exercised when agents that 
are inhibitors or substrates of P-gp are administered concomitantly with AZD1775.
Recent in-vitro transporter studies have shown AZD1775 to be an inhibitor of BCRP (IC50 5.1 
μM).  This finding is particularly relevant for drugs administered orally where exposure is

normally limited by BCRP-mediated efflux, in particular some statins, such as rosuvastatin.  
Other drugs where the disposition is mediated via BCRP should be administered with caution, 
dose modification considered or substituted by an alternative drug. 
Use of metformin should be used with caution in this study as recent in vitro transporter data 
have shown AZD1775 is an inhibitor of Multidrug and Toxin Extruder 1 (MATE1) and 
MATE2K.
Caution should be used when administering drugs that are substrates of these transporters (e.g. 
cimetidine, acyclovir, fexofenadine) as the clinical relevance of AZD1775 inhibition of the 
MATE pathway is not known in these compounds.
Herbal preparations/medications can be substrates, inhibitors and inducers, similar to any 
registered medication.  Herbal preparations are therefore not allowed throughout the study.  
These herbal medications include, but are not limited to: St. John’s wort, kava, ephedra (ma 
huang), gingko biloba, dehydroepiandrosterone (DHEA), yohimbe, saw palmetto, and 
ginseng.  
In addition, any other drugs should be avoided at the Investigator’s discretion if, in their 
opinion, the co-administration with AZD1775 may increase the risk of a clinically significant 
drug interaction.
A list of the main CYP3A4 substrates, inhibitors (strong and moderate) and inducers, 
CYP2C19 substrates, P-gp substrates and inhibitors and BCRP substrates are shown below.
