Eligibility criteria:
ELIGIBILITY CRITERIA:
Patients must have histologically confirmed solid tumors for which all standard therapy known to prolong survival have failed or for which standard therapies do not exist.

Patients must have measurable disease or evaluable disease for the escalation phase; for the 6 additional patients enrolled at maximum tolerated dose (MTD) for further evaluation of pharmacokinetics (PK) and pharmacodynamics (PD) endpoints (Expansion Cohort A). For the 6-patient breast cancer gene (BRCA)-mutation expansion cohort, patients must have measurable disease; however, tumor biopsies are optional. For Expansion Cohort B, patients must have tumor amenable to biopsy (excisional or incision biopsies of skin or head (H) & neck (N) lesions under visualization) and willingness to undergo a tumor biopsy or patient will be undergoing a procedure due to medical necessity during which the tissue may be collected, or tumor biopsy tissue from a previous research study or medical care is available for submission at registration. Criteria for the submission of tissue are:

Tissue must have been collected within 3 months prior to registration
Patient has not received any intervening therapy for their cancer since the collection of the tumor sample
Tumor tissue must meet the minimum requirements
Patients must have completed any chemotherapy, radiation therapy, surgery, or biologic therapy greater than or equal to 3 weeks (or > 5 half-lives, whichever is shorter) prior to entering the study. Patients must be greater than or equal to 2 weeks since any prior administration of a study drug in an exploratory Investigational New Drug (IND)/Phase 0 study or more than or equal to 1 week from palliative radiation therapy. Patients must have recovered to eligibility levels from prior toxicity or adverse events.
Age greater than or equal to 18 years of age.
Eastern Cooperative Oncology Group (ECOG) performance status less than or equal to 1 (Karnofsky >60%)
Life expectancy of greater than 3 months.

Patients must have normal organ and marrow function as defined below:

leukocytes greater than or equal to 3,000/mcL
absolute neutrophil count greater than or equal to 1,500/mcL
platelets greater than or equal to 100,000/mcL
hemoglobin >9 g/dL
total bilirubin less than or equal to 1.5 times institutional upper limit of normal
Aspartate aminotransferase (AST) serum glutamic-oxaloacetic transaminase (SGOT)/alanine aminotransferase (ALT) serum glutamate-pyruvate transaminase (SGPT) less than or equal to 3 times institutional upper limit of normal
creatinine less than or equal to 1.5 times institutional upper limit of normal OR
creatinine clearance greater than or equal to 60 mL/min/1.73 m(2) for patients with creatinine levels above institutional normal.
The effects of Adavosertib (AZD1775) on the developing human fetus are unknown. For this reason and because molecular inhibitors of Wee1 kinase are known to be teratogenic, women of child-bearing potential (WoCBP) may be included only if acceptable contraception is in place for two weeks before study entry, for the duration of the treatment with the study drug, and for 2 months after the last dose of AZD1775. Male patients who are involved in the study must agree to avoid procreative and unprotected sex (i.e., by using acceptable forms of contraception) and must not donate sperm during the study and for 3 months after the last dose of AZD1775. Where the female partner is pregnant or not using effective birth control, men should be advised to abstain while in the study and for 3 months after the last dose of AZD1775. Female partners, who are of child-bearing potential, of men participating in clinical studies of AZD1775 will also be required to use effective contraceptive measures while their partner is on study drug and for 3 months thereafter. Male patients will be advised to arrange for the freezing of sperm samples prior to the start of the study should they wish to father children while on AZD1775 or during the 3 months after stopping AZD1775.
Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with the study drugs, breastfeeding should be discontinued prior to the first of study drug and women should refrain from nursing throughout the treatment period and for 14 days following the last dose of study drug.
Patients must be able to swallow whole tablets or capsules. Nasogastric or G-tube administration is not allowed. Any gastrointestinal disease which would impair ability to swallow, retain, or absorb drug is not allowed.
Ability to understand and the willingness to sign a written informed consent document.
Patients with prostate cancer can continue to receive treatment with gonadotropin-releasing hormone (GnRH) agonists while on study, as long as there is evidence of disease progression on therapy.

EXCLUSION CRITERIA:

Patients who are receiving any other investigational agents.
Patients with known active brain metastases or carcinomatous meningitis are excluded from this clinical trial. Patients whose brain metastatic disease status has remained stable for greater than or equal to 4 weeks following treatment of brain metastases are eligible to participate at the discretion of the principal investigator.
Eligibility of subjects receiving any medications or substances with the potential to affect the activity or pharmacokinetics of AZD1775 will be determined following review by the principal investigator.
Patients receiving any medications or substances that are inhibitors or inducers of Cytochrome P450 3A4 (CYP3A4), or CYP3A4 substrates need to be reviewed by the principal investigator. Continuation of such medications will be at the discretion of the principal investigator. Concomitant use of aprepitant or fosaprepitant is prohibited. 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. The use of sensitive substrates of CYP3A4, such as atorvastatin, simvastatin and lovastatin, is also prohibited in this study. Herbal preparations are not allowed throughout the study. These herbal medications include but are not limited to: St. John's wort, kava, ephedra (mahung), gingko biloba, dehydroepiandrosterone (DHEA), yohimbe, saw palmetto and ginseng.
Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
Pregnant women are excluded from this study because the effects of the study drugs on the developing fetus are unknown.
Human immunodeficiency virus (HIV) positive patients on antiretroviral therapy are ineligible because of the potential for pharmacokinetics (PK) interactions.

INCLUSION OF WOMEN AND MINORITIES:

Both men and women of all races and ethnic groups are eligible for this trial.
