• Total bilirubin =< 1.5 x upper limit of normal (ULN) (within 7 days prior to initiation of therapy)
• Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) =< 2.5 x upper limit of normal unless the liver is involved with tumor, in that case, AST and ALT must be =< 5 x upper limit of normal (within 7 days prior to initiation of therapy)
• Creatinine clearance > 50 mL/min (assessed by Cockcroft Gault estimation) and creatinine < 1.5 x ULN (within 7 days prior to initiation of therapy)
• Patients must have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
• 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 90 days after the last dose of AZD1775; WoCBP are defined as those who are not surgically sterile (ie, bilateral tubal ligation, bilateral oophorectomy, or complete hysterectomy) or postmenopausal (defined as 12 months with no menses without an alternative medical cause); acceptable methods of contraception include true abstinence in line with the preferred and usual lifestyle choice of the patient, tubal ligation, vasectomized partner, barrier methods (eg, cap plus spermicide, sponge plus spermicide, diaphragm plus spermicide, or male condom plus a spermicide), intrauterine device methods (eg, Copper T or Levonorgestrel-releasing intrauterine system), or hormonal methods (eg, any registered and marketed contraceptive agent that contains an estrogen and/or a progestational agent and that is administered via the oral, subcutaneous, transdermal, intrauterine, or intramuscular route as an implant, hormone shot or injection, combined pill, minipill or patch); all methods of contraception (with the exception of total abstinence) should be used in combination with the use of a condom by their male sexual partner for intercourse; periodic abstinence, the rhythm method, and the withdrawal method are not acceptable methods of birth control; all WoCBP must have a negative pregnancy test within 3 days prior to study the initiation of therapy; should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately
• Women must not breast-feed while taking the study medications
• Patients must be able to understand and willing to sign an informed consent

Exclusion Criteria:

• Prior treatment for ovarian, fallopian tube, or primary peritoneal cancer
• Current receipt of any other investigational agents or any additional anti-cancer agents for this or any other disease
• Known central nervous system (CNS) disease other than neurologically stable, treated brain metastases -- defined as metastasis having no evidence of progression or hemorrhage after treatment for at least 2 weeks
• Presence of other active cancers; patients with stage I cancer who have received definitive local treatment within the last 3 years, and whom are considered unlikely to recur, are eligible; all patients with previously treated in-situ carcinoma (i.e., non-invasive) are eligible, as are patients with prior non-melanoma skin cancers
• Major surgical procedures =< 28 days of beginning study treatment, or minor surgical procedures =< 7 days (minor procedures done at time of laparoscopy are allowed); no waiting required following port-a-cath placement
• Significant symptom burden from presumed diagnosis including large volume ascites, pain requiring narcotic medication, or shortness of breath on exertion
• Myocardial infarction within 6 months before starting therapy, symptomatic congestive heart failure (New York Heart Association > class II), unstable angina, or unstable cardiac arrhythmia requiring medication
• Corrected QT interval (QTc) > 470 msec (as calculated by Fridericia correction formula) at study entry or congenital long QT syndrome
• Caution should be exercised when inhibitors or substrates of P-glycoprotein (P-gP), substrates of cytochrome P450 family 1 subfamily A member 2 (CYP1A2) with a narrow therapeutic range, sensitive substrates of cytochrome P450 family 2 subfamily C member 19 (CYP2C19) or CYP2C19 substrates with a narrow therapeutic range are administered with AZD1775
• Herbal preparations 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; not willing to avoid grapefruit, grapefruit juices, grapefruit hybrids, Seville oranges, pummelos, and exotic citrus fruits from 14 days prior to the dose of study medication and during the entire study due to potential CYP3A4 interaction with the study medication; orange juice is allowed
• Any known hypersensitivity or contraindication to the components of study treatment
• Pregnant or breast-feeding
• As judged by the investigator, any evidence of severe or uncontrolled systemic diseases (e.g., severe hepatic impairment, interstitial lung disease [bilateral, diffuse, parenchymal lung disease], uncontrolled chronic renal diseases [glomerulonephritis, nephritic syndrome, Fanconi syndrome or renal tubular acidosis]), serious active infection or current unstable or uncompensated respiratory or cardiac conditions, or uncontrolled hypertension (blood pressure >= 140/90), active bleeding diatheses or active infection including hepatitis B, hepatitis C, and human immunodeficiency virus; screening for chronic conditions and infectious diseases is not required
• As judged by the investigator, the patient is unsuitable to participate in the study and the patient is unlikely to comply with study procedures, restrictions, and requirements
• Subject has had prescription or non-prescription drugs or other products known to be sensitive cytochrome P450 family 3 subfamily A member 4 (CYP3A4) substrates or CYP3A4 substrates with a narrow therapeutic index, or to be moderate to strong inhibitors / inducers of CYP3A4 which cannot be discontinued two weeks prior to day 1 of dosing and withheld throughout the study until 2 weeks after the last dose of study drug; co-administration of aprepitant or fosaprepitant during this study is prohibited
