You may not qualify if…

• Prior treatment with a PARP inhibitor.
• Use of an investigational drug during the past 30 days or 5 half-lives (whichever is longer) prior to 1st dose of study treatment.
• Use of anti-cancer treatment drug ≤ 21 days or 5 half-lives (whichever is shorter) prior to 1st dose of study treatment. For drugs for which 5 half-lives is ≤ 21 days, a minimum of 10 days between termination of the prior treatment and administration of study treatment is required.
• Radiotherapy (except for palliative reasons) within ≤ 21 days prior to study treatment.
• No other anti-cancer therapy (except for palliative local radiotherapy), biological therapy, or other novel agent is permitted while the patient is receiving study medication. Patients on luteinizing hormone-releasing hormone (LHRH) analogue treatment for more than 6 months are allowed entry into the study and may continue at the discretion of the investigator.
• Major surgical procedures ≤ 28 days of beginning study treatment, or minor surgical procedures ≤ 7 days. Patients must have recovered from any of the effects of any major surgery. No waiting period required following port-a-cath placement.
• Persistent Grade >1 toxicity from prior cancer therapy (except alopecia or anorexia).
• Patient has an inability to swallow oral medications. Note: Patients with percutaneous endoscopic gastrostomy (PEG) tube or receiving total parenteral nutrition (TPN) are not eligible.
• Known malignant central nervous system (CNS) disease other than neurologically stable, treated brain metastases, defined as metastasis having no evidence of progression or haemorrhage for at least 2 weeks after treatment. Must be off any systemic corticosteroids for the treatment of brain metastases for at least 14 days prior to enrolment.
• Patient has had prescription or non-prescription drugs or other products known to be sensitive to CYP3A4 substrates or CYP3A4 substrates with a narrow therapeutic index, or to be moderate to strong inhibitors/inducers of CYP3A4 which cannot be discontinued 2 weeks prior to the olaparib PK sub-study dosing and withheld throughout the study until 2 weeks after the last dose of study drug.
• The use of sensitive substrates of CYP3A4, such as atorvastatin, simvastatin and lovastatin are prohibited in this study. Co-administration of aprepitant or fosaprepitant during this study is prohibited.
• Caution should be exercised when inhibitors or substrates of P-glycoprotein (P-gp), substrates of CYP1A2 with a narrow therapeutic range, sensitive substrates of CYP2C19 or CYP2C19 substrates with a narrow therapeutic range are administered with AZD1775.
• Herbal preparations are not allowed throughout the study, including but not limited to: St. John's wort, kava, ephedra (ma hung), gingko biloba, dehydroepiandrosterone (DHEA), yohimbe, saw palmetto and ginseng. Patients should stop using these herbal medications 7 days prior to first dose of study treatment.
• Any known hypersensitivity or contraindication to the components of the study drug AZD1775 or olaparib.
• Patients with either previous or current myelodysplastic syndrome/acute myeloid leukaemia or features suggestive of MDS/AML.
• Any of the following cardiac diseases currently or within the last 6 months as defined by New York Heart Association (NYHA) ≥ Class 2.
• Unstable angina pectoris
• Congestive heart failure
• Acute myocardial infarction
• Conduction abnormality not controlled with pacemaker or medication
• Significant ventricular or supraventricular arrhythmias (patients with chronic rate controlled atrial fibrillation in the absence of other cardiac abnormalities are eligible)
• AZD1775 should not be given to patients who have a history of Torsades des pointes (TdP) unless all risk factors that contributed to TdP have been corrected.
• Mean resting corrected QTc interval using the Fridericia formula [QTcF]) ≥ 470 msec for female patients and ≥ 450 msec for male patients from 3 electrocardiograms (ECGs) performed 2-5 minutes apart at study entry or congenital long QT syndrome. .
• Pregnant or breastfeeding.
• Serious known active infection at the time of enrolment, or another serious underlying medical condition that would impair the ability of the patient to receive study treatment.
