2. Patient must have MRI evidence of disease recurrence
3. Patients must have Eastern Cooperative Oncology Group (ECOG) performance status ≤2
4. Patients ≥ 18 years of age
5. Adequate hematologic, renal, and hepatic function
6. Patients must not have co-morbid condition(s) that, at the opinion of the investigator, prevent safe surgical treatment

8. Patients must not be pregnant or nursing
9. Patients must have archival tumor tissue block available for research use
10. Ability to understand and the willingness to sign a written informed consent document.
11. Patient has voluntarily agreed to participate by giving written informed consent.

Exclusion Criteria:

1. Less than 18 years of age
2. Diagnosis of anything other than first-recurrence GBM
3. GBM tissue from first-resection not available
4. Previous treatment with AZD1775
5. Uncontrolled concurrent 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
6. Patient has known hypersensitivity to the components of potential study therapy or its analogs.
7. Patient has had prescription or non-prescription drugs or other products known to be metabolized by cytochrome P450 3A4 (CYP3A4), or to inhibit or induce CYP3A4, which cannot be discontinued prior to Day 1 of dosing and withheld throughout the study until 2 weeks after the last dose of study medication (inhibitors generally for 5 half-lives). Medications of particular concern are the following inhibitors of CYP3A4: azole antifungals (ketoconazole itraconazole, fluconazole and voriconazole), macrolide antibiotics (erythromycin, clarithromycin), cimetidine, HIV protease inhibitors, nefazodone and the following inducers of CYP3A4: phenytoin, barbiturates and rifampicin. Substrates of CYP3A4 include statins (lovastatin, simvastatin), midazolam, terfenadine, astemizole, and cisapride. CYP3A4.
8. Patient has a history or current evidence of any condition, therapy, or lab abnormality that might confound the results of the study, interfere with the patient's participation for the full duration of the study, or is not in the best interest of the patient to participate.
9. Patient has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial.
10. Patient is, at the time of signing informed consent, a regular user (including "recreational use") of any illicit drugs or had a recent history (within the last year) of drug or alcohol abuse.
11. Patients expecting to reproduce within the projected duration of the study (estimated to be 1 year), and women who are pregnant or breastfeeding.
12. Patient is known to be suffering from Acquired Immune Deficiency Syndrome (AIDS).
13. Patient has known history of Hepatitis B or C.
14. Patient has symptomatic ascites or pleural effusion. A patient who is clinically stable following treatment for these conditions is eligible.
15. Patient has a clinical history suggestive of Li-Fraumeni Syndrome.
