Trial Information
Phase I/II Trial of Dasatinib (Sprycel) With Radiation Therapy and Concomitant and Adjuvant Temozolomide in Patients With Newly-Diagnosed Glioblastoma
PHASE I AND PHASE II
The Study Drugs:
Dasatinib is designed to change the function of certain genes. By changing the function of
these genes, it may prevent cancer from growing and spreading. It is also designed to block
or lower the activity of one or more tumor-causing proteins responsible for the uncontrolled
growth of tumor cells, which may result in shrinking or stopping tumor growth.
Temozolomide is designed to kill cancer cells by damaging DNA (the genetic material of
cells). The damaged DNA may cause tumor cell death.
**********************************
PHASE I
Study Groups:
If you are found to be eligible to take part in this study, you will be assigned to a dose
level of dasatinib based on when you joined this study. Up to 2 dose levels of dasatinib
will be tested. Three (3) participants will be enrolled at each dose level. The first
group of participants will receive the lowest dose level. Each new group will receive a
higher dose than the group before it, if no intolerable side effects were seen. This will
continue until the highest tolerable dose of dasatinib given in combination with
temozolomide is found.
All the groups will take the same dose level of temozolomide for the entire study.
The amount of study drugs you receive may change if you experience side effects. If at any
time you experience any intolerable side effects, tell the study doctor right away.
Study Drug Administration:
During Radiation:
As a part of standard of care, you will receive radiation therapy Monday-Friday for a total
of 30 radiation treatments (about 6 weeks).
Every day while you are receiving radiation, you will take the temozolomide by mouth once a
day for up to a maximum of 7 weeks.
You should swallow temozolomide whole, one right after the other, without chewing them. If
you vomit while taking temozolomide, you cannot take more capsules before the next scheduled
dose. They should be taken on an empty stomach (at least 1 hour before and 2 hours after
eating) with 1 cup (about 8 oz.) of water.
Every day while you are receiving radiation, you will take dasatinib by mouth 1 time a day
for up to a maximum of 7 weeks. You should take dasatinib without food (1 hour before or 2
hours after eating), with at least 1 cup (8 oz.) of water.
After Radiation:
After the radiation therapy ends, every day, you will continually take dasatinib by mouth 1
time a day.
You will not take temozolomide for about 4 weeks after the radiation therapy ends. After 4
weeks, you will begin taking temozolomide 1 time a day, by mouth, on Days 1-5 of each 28 day
study cycle.
Study Visits:
Four (4) weeks after the end of radiation, then every 4 weeks after that, the following
tests and procedures will be performed:
- You will have a physical exam, including measurement of your vital signs.
- You will have a neurological exam.
- You will have a performance status evaluation.
- You will be asked about any drugs you may be taking and if you have experienced any
side effects.
- Blood (about 1 teaspoon) will be drawn to check your blood's ability to clot normally.
Every week for the first 6 weeks, then every 4 weeks after that, you will be asked if you
have experienced any side effects.
If you are taking an anti-seizure drug, every 2 weeks for the first 6 weeks and then every 4
weeks after that, blood (about 1 teaspoon) will be drawn to check the levels of anti-seizure
drug in your blood.
At Week 6, then before each cycle after radiation for the first 6 cycles, you will have an
ECG.
Every week for the first 6 weeks, then on Days 1 and 22 of every cycle after radiation,
blood (about 3 teaspoons) will be collected for routine tests.
Four (4) weeks after the end of radiation, then every 8 weeks after that, you will have an
MRI scan to check the status of the disease.
Length of Study:
You may continue taking temozolomide for up to 12 cycles. You may continue taking dasatinib
for as long as you are benefitting. You will be taken off study early if the disease gets
worse or you experience intolerable side effects.
End-of-Study Visit:
After you go off study, you will have an end-of-study visit. At this visit, the following
tests and procedures will be performed:
- Your complete medical history will be recorded.
- You will have a physical exam.
- You will have a performance status evaluation.
- You will be asked about any drugs you may be taking and if you have experienced any
side effects.
- You will have a neurological exam.
- Blood (about 3 1/2 teaspoons) will be collected for routine tests and to check your
blood's ability to clot normally.
- If you are taking an anti-seizure drug, blood (about 1 teaspoon) will be drawn to check
the level of anti-seizure drug in your blood.
Long-Term Follow-up visit:
After the end-of-study visit, the study team/staff will contact you by telephone every 3
months to check how you are doing. Each phone call will take about 5 minutes.
This is an investigational study. Temozolomide is FDA approved and commercially available
for the treatment of brain tumors. Dasatinib is FDA approved and commercially available for
the treatment of some types of leukemia, but it is experimental for use in brain tumors. In
addition, the combination of temozolomide and dasatinib is experimental for use in brain
tumors. At this time, the combination is only being used in research.
Up to 72 participants will take part in this study. Up to 72 will be enrolled at M. D.
Anderson.

Up to 72 participants will take part in this study. Up to 72 will be enrolled at M. D.
Anderson.
Inclusion Criteria:
1. Patients with newly diagnosed histologically proven intracranial supratentorial GBM
or gliosarcoma (GS) will be eligible for this protocol. Patients will not be eligible

registration and on a corticosteroid dose that has been stable or decreasing for at
least 5 days. If the corticosteroid dose is increased between the date of imaging and
registration, then a new baseline MRI/CT is required. The same type of scan, i.e.,
MRI or CT, must be used throughout the period of protocol treatment for tumor
measurement. The use of MRI rather than CT is preferred.

registration. Eligibility level for hemoglobin may be reached by transfusion.
11. Patients must be willing to forego other cytotoxic and non-cytotoxic drug therapy
against the tumor while enrolled in the study.
12. Women of childbearing potential must have a negative beta-HCG pregnancy test
documented within 14 days prior to registration. Should a woman become pregnant or
suspect she is pregnant while participating in this study, she should inform her
treating physician immediately.
Exclusion Criteria:
1. Patients must not have received prior Gliadel wafers.
2. Patients must not have received any investigational agents within 30 days prior to
commencing study treatment.
3. Patients must not have any significant medical illnesses that in the investigator's
opinion cannot be adequately controlled with appropriate therapy or would compromise
the patient's ability to tolerate this therapy.
4. Patients with a history of any other cancer (except non-melanoma skin cancer or
carcinoma in situ of the cervix), unless in complete remission and off of all therapy
for that disease for a minimum of 3 years are ineligible.
5. Uncontrolled intercurrent illness including, but not limited to, ongoing or active
infection or psychiatric illness/social situations that would limit compliance with
study requirements.

11. Patients with known HIV are ineligible for this study.
12. Patients must not have any disease that will obscure toxicity or dangerously alter
drug metabolism.
13. Patients must not have received prior therapy with dasatinib for any indication.
14. Inclusion of Women and Minorities: Both men and women and members of all races and
ethnic groups are eligible for this trial.
15. Patients on the following medication will be excluded: a) Anticonvulsants: Patients
on Enzyme Inducing Anticonvulsants (EIAED) will be excluded. If patients were
previously on EIAEDs that have been discontinued, patients must have been off EIAEDs
for >/= 2 weeks prior to initiation of dasatinib. It should also be noted whether
patients were or were not previously receiving EIAEDs and the last date of
administration of EIAEDs.
16. ( 15. continued) b) Antacids: Use of H2 blockers and proton pump inhibitors is
prohibited because systemic antacids (H2 inhibitors, proton pump inhibitors) decrease
dasatinib absorption. Patients who require antacids should use short acting, locally
active agents (e.g., Maalox, Mylanta etc.). However, these agents should not be taken
within either 2 hours before or 2 hours after the dasatinib dose. This is
particularly important in patients with glioblastoma who are frequently on
dexamethasone and prophylactic H2 blockers or proton pump inhibitors.
17. (15. continued) c) Anticoagulants/Anti-platelets: Patients on therapeutic (treatment)
dose of anticoagulants (e.g. warfarin, low molecular-weight heparin) are not
eligible. Patients are not allowed to take aspirin, clopidogrel, ticlopidine,
Aggrenox. Patients on prophylactic anticoagulation may be enrolled and treated on
study as long as their platelet count is monitored closely and maintained at >75,000
while they are receiving Dasatinib.
18. (15. continued) d) Ibuprofen and other NSAIDS: Ibuprofen and other non-steroidal
anti-inflammatory drugs (NSAIDS) can inhibit platelet function. Patients may not take
ibuprofen or other NSAIDs at study entry and must have stopped these agents >/=7 days
prior to starting dasatinib to allow for an appropriate wash-out period.
19. (15. continued) e) Inducers and Inhibitors of CYP3A4: Patients required to be on any
of those drugs will be excluded (with the exception of Dexamethasone, but all efforts
should be made to reduce the dose of dexamethasone). Patients may discontinue drug at
least 7 days prior to starting dasatinib.

causing Torsades de Pointes including: (Patients must discontinue drug at least 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.
