Eligibility Criteria
Inclusion Criteria: Age ≥ 24 years of age Note: Fluoxetine has a warning about suicidal thoughts in children, adolescents, and young adults. Short-term studies did not show an increase in the risk of suicidality with antidepressants compared to placebo in adults beyond age 24. Patients with recurrent glioma Tumor volume ≥ 1 cm3 Clinical indication for craniotomy for biopsy and resection of the lesion Clinical indication for repeat treatment with Temozolomide Karnofsky Performance Status (KPS) > 70% Adequate organ function: platelets > 100,000/µL, hemoglobin >9 gm/dL, ANC > 1000/µL; creatinine < 1.5x upper limit of normal (ULN), total bilirubin < 1.5x ULN, AST/ALT < 2.5x ULN within 72 hours prior to first administration of Fluoxetine Able to undergo MRI brain with and without contrast If the patient is a sexually active female of childbearing potential, whose partner is male, or if the patient is a sexually active male, whose partner is a female of childbearing potential, the patient must use appropriate contraceptive measures for the duration of the treatment and for 6 months afterwards. Female patients of childbearing potential must have a negative serum pregnancy test at the time of screening and within 48 hours of starting the infusion of the study drug.

Arms of the Study
Arm 1
Arm 2
Experimental
Active Comparator
Fluoxetine pre-surgery
Temozolomide pre-surgery
Patients randomized to the experimental arm will receive fluoxetine at 20 mg/day for 5 days (initiation dose) followed by a maintenance dose of 40 mg/day starting on Day 6 (dose level 1) or 60 mg/day starting on Day 6 (dose level 2).
Temozolomide pre-surgery (control) arm will receive 50 mg/m2 temozolomide daily for 7 days (Days 1-7), followed by resection or biopsy 21 days after initiation of the temozolomide cycle.
