简要总结
This phase II trial studies how well dasatinib works in treating patients with glioblastoma multiforme or gliosarcoma that has come back. Dasatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
详细描述
PRIMARY OBJECTIVES:
I. To determine the therapeutic efficacy of dasatinib in all patients (i.e., stages 1B and 2 combined) with recurrent/progressive glioblastoma (GBM) as measured by 6-month progression-free survival.
SECONDARY OBJECTIVES:
I. To determine the therapeutic efficacy of dasatinib for stage 1B patients with recurrent/progressive GBM as measured by a hybrid endpoint of 6-month progression-free survival OR objective response of (complete response [CR] or partial response [PR]) rate.
II. To determine patient overall survival. III. To determine the toxicity of dasatinib in the treatment of patients with GBM.

- •Creatinine =< 3 X institutional upper limit of normal or creatinine clearance >= 60 mL/min/1.73 m^2 for patients with creatinine levels above institutional normal
- •All patients must have undergone prior treatment with radiotherapy and temozolomide; no other prior treatments are allowed
- •There must be unequivocal radiographic evidence for tumor progression by MRI or CT scan, and the same type of scan (i.e., MRI or CT) must be used throughout the period of protocol treatment for tumor measurement; patients must be on a stable or decreasing dose of corticosteroids for at least 5 days before the baseline MRI/CT is performed
- •Patients having undergone recent surgery for recurrent/progressive disease are eligible as long as they have recovered from the effects of surgery; patients who recently underwent resection without measurable disease post-operatively are also eligible
- •Measurable disease is not required for eligibility in patients who recently underwent resection as long as the following conditions are met as applicable:
- •Progression of disease led to the surgery
- •Gliadel wafers were not placed during the most recent surgery
- •Neither convection enhanced delivery nor catheters for infusion of chemotherapy were used during the most recent surgery
- •Radioactive seeds were not placed during the most recent surgery
- •The histology of the most recent surgery documented recurrent/persistent/progressive malignant glioma
- •Women of childbearing potential must have a negative beta human chorionic gonadotropin (B HCG) pregnancy test =< 3 days prior to registration
- •Patient must sign study-specific informed consent prior to study entry
排除标准
- •Prior invasive malignancy (except non-melanomatous skin cancer) unless disease free for a minimum of 3 years; (for example, carcinoma in situ of the breast, oral cavity, or cervix are all permissible)
- •Radiotherapy within 4 weeks or temozolomide within 14 days prior to registration or failure to recover from adverse events of either radiotherapy or temozolomide
- •Patients may not be receiving any other investigational agents
- •Severe, active comorbidity, defined as follows:
- •Any clinically significant cardiovascular disease including the following:
- •Unstable angina and/or congestive heart failure requiring hospitalization within the past 6 months
- •Transmural myocardial infarction or ventricular tachyarrhythmia within the past 6 months
- •Prolonged corrected QT interval (QTc) > 480 msec (Fridericia correction)

- •Major conduction abnormality (unless a cardiac pacemaker is present)
- •Acute bacterial or fungal infection requiring intravenous antibiotics at the time of registration
- •Chronic obstructive pulmonary disease exacerbation or other respiratory illness requiring hospitalization or precluding study therapy at the time of registration
- •Acquired immune deficiency syndrome (AIDS) based upon current Centers for Disease Control and Prevention (CDC) definition; note, however, that human immunodeficiency virus (HIV) testing is not required for entry into this protocol
- •Pregnancy or women of childbearing potential and men who are sexually active and not willing/able to use medically acceptable forms of contraception; breastfeeding should be discontinued if the mother is treated with dasatinib
- •History of allergic reactions attributed to compounds of similar chemical or biologic composition to dasatinib

结局指标
主要结局
Number of Patients Achieving 6-month Progression-free Survival (6mPFS)
时间窗: Registration to 6 months
This study utilized a two-stage phase II design (Stage 1B and 2). The primary endpoint of 6-month progression-free survival (6mPFS) would be assessed based on the patients combined from 1B and 2 if the study continued to Stage 2. Null hypothesis = 11%; alternative hypothesis = 25%. Simon's minmax 2-stage design was used with type I and type II error both set at 10%. If the first stage met its criteria (see secondary outcome measure), then accrual would continue, otherwise there would be no further accrual and the alternative hypothesis would be rejected. Following Stage 2 accrual completion and 6 months of follow-up, if 9 or more patients were alive without progression by 6 months, the null hypothesis would be rejected in favor of the alternative.
