  Purpose

The primary objective of this study is to determine the maximum tolerated dose (MTD) and dose limiting toxicity (DLT) of dasatinib when combined with protracted, daily temozolomide (TMZ). Secondary objectives are: To further evaluate the safety and tolerability of dasatinib plus protracted, daily TMZ; 2. To evaluate the pharmacokinetics of dasatinib when administered with protracted, daily TMZ among recurrent malignant glioma patients who are on and not on CYP-3A enzyme inducing anti-epileptic drugs (EIAEDs); 3. To evaluate for anti-tumor activity with this regimen in this patient population.

Detailed Description:

This is an open-label, single center, one-arm phase I dose-escalation study of dasatinib plus protracted , daily TMZ administered orally on a continuous daily dosing schedule among adult patients with recurrent or relapsing malignant glioma. The study format includes a classical "3+3" dose escalation design to determine the MTD and DLT of dasatinib plus protracted, daily TMZ among recurrent malignant glioma patients. Patients will be stratified based on whether they are receiving EIAED and each stratum will independently dose escalate. Additionally, the study will characterize the safety, tolerability, biologic activity, and pharmacokinetic profile of dasatinib when used in combination with protracted, daily TMZ.

Patients will start treatment on day 1 of cycle 1 with dasatinib. For patients undergoing dasatinib pharmacokinetic (PK) analysis, dasatinib will be administered alone until initial PK assessments are collected. Protracted TMZ will be initiated after initial dasatinib PK assessments are collected and will continue to be administered with dasatinib on a continuous daily dosing schedule. The initial dasatinib PK assessments will be collected over 24 hours between days 3-7 of cycle 1. Patients not undergoing dasatinib PK collections will begin both dasatinib and protracted, daily TMZ together on day 1, cycle 1.

The protracted, daily TMZ dose will be 50 mg/m² daily for all patients. The dose level of dasatinib will be increased in successive cohorts. Cohorts of 3-6 patients will accrue at each dose level until MTD is defined. Each cohort will consist of a minimum of 3 newly enrolled patients. Intra-patient dose escalation is not permitted. It is estimated that this study will enroll a minimum of 30 patients (up to 4 dose levels/stratum; 3 patients/dose level for levels 1-3 and 6 patients at level 4) and a maximum of 48 patients (6 patients/dose level; 4 dose levels/stratum). Cohorts may be expanded at any dose level for further elaboration of safety and pharmacokinetic parameters as required.

The primary safety and efficacy analysis will be conducted on all patient data at the time all patients who are still receiving study drug will have completed at least 4 cycles of treatment. The additional data for any patients continuing to receive study drug past this time, as allowed by the protocol, will be further summarized in a report once these patients either completed or discontinued the study. Prior to the primary analysis, an additional safety report may be prepared.

The most common side effects include vomiting, diarrhea, anorexia (loss of appetite), fluid retention, fatigue, headache, rash, hypocalcemia (low calcium level), and decreases in blood counts. Other possible side effects may include nausea, joint pain, muscle aches, generalized pain, abdominal pain, and fever. Rare side effects may include QTc prolongation (heart beat changes), pulmonary edema (fluid around the lungs), difficulty breathing, cough, hemorrhage, gastrointestinal bleeding, pneumonia, cardiac effusion (fluid in the sac surrounding the heart), and cardiac failure. Temodar has been well tolerated by both adults and children with the most common toxicity being mild myelosuppression. Other, less likely, potential toxicities include nausea and vomiting, constipation, headache, alopecia, rash, burning sensation of skin, esophagitis, pain, diarrhea, lethargy, hepatotoxicity, anorexia, fatigue and hyperglycemia. As in the case with many anti-cancer drugs, Temodar may be carcinogenic. Rats given Temodar have developed breast cancer.

  18. Concurrent administration of warfarin, rifampin or St. John's Wort, except for low-dose warfarin (1mg po DAILY);
  19. Clinically serious infection requiring active intervention (CTCAE Gr.2 or greater);
  20. Hypokalemia or hypomagnesemia if it cannot be corrected;
  21. Concomitant Medications, consider the following prohibitions:

    1. Drugs that are generally accepted to have a risk of causing Torsades de Pointes including: (Patients must discontinue drug 7 days prior to starting dasatinib)

      1. quinidine, procainamide, disopyramide
      2. amiodarone, sotalol, ibutilide, dofetilide
      3. erythromycin, clarithromycin
      4. chlorpromazine, haloperidol, mesoridazine, thioridazine, pimozide
      5. cisapride, bepridil, droperidol, methadone, arsenic, chloroquine, domperidone, halofantrine, levomethadyl, pentamidine, sparfloxacin, lidoflazine.
    2. Drugs that reduce dasatinib exposure such as H2 blockers or proton-pump inhibitors (eg famotidine and omeprazole), which can cause long-term suppression of gastric acid secretion. The concomitant use of H2 blockers or proton pump inhibitors with dasatinib is in general not recommended and antacids should be considered in place of H2 blockers or proton pump inhibitors in patients receiving dasatinib therapy. However, given that nearly all recurrent malignant brain tumor patients are on dexamethasone for increased intracranial pressure, such patients must also receive effective medical therapy to prevent complications related to increased gastric acid secretion due to chronic dexamethasone therapy. Therefore all patients enrolled on the current protocol will receive standard H2 blocker (preferred) or proton pump inhibitor (PPI) therapy to be administered on a daily basis each evening. Dasatinib will be administered each morning in order to maximize the time interval from administered H2 blocker (preferred) or proton pump inhibitor (PPI).
    3. Drugs that cause hypocalcemia (i.e. IV bisphosphonates will be withheld for the first 8 weeks of dasatinib therapy due to risk of hypocalcemia).
    4. Any prohibited CYP3A4 inhibitors; 22. Prisoners or subjects who are compulsorily detained (involuntarily incarcerated) for treatment of either a psychiatric or physical (e.g., infectious) illness.
