Summary
The goal of this clinical research study is to learn if pazopanib when given in combination with topotecan can help to control glioblastoma. The safety of this drug combination will also be studied.

The study doctor can explain how the study drugs are designed to work.
Detailed Description
Study Groups:

If you are found to be eligible to take part in this study, you will be assigned to a study group based on if you have received bevacizumab or not:

- You will be in Group A if you have not received bevacizumab in the past.

- You will be in Group B if you have received bevacizumab in the past.

Both groups will receive pazopanib and topotecan at the same dose level and on the same schedule. Up to 34 participants will be enrolled in Group 1 and up to 32 participants will be enrolled in Group 2.

Study Drug Administration:

Each cycle is 28 days.

You will take capsules of topotecan by mouth 1 time everyday at about the same time each day. You should swallow the capsules whole with at least 1 cup (8 ounces) of water, with or without food.

You will take tablets of pazopanib by mouth 1 time every day at about the same time each day. They should be taken on an empty stomach (at least 1 hour before and 2 hour after eating) with about 1 cup (8 ounces) of water.

Pazopanib should be taken whole with water and must not be broken or crushed.

If a dose of pazopanib is missed, it should not be taken if it is less than 12 hours until the next dose.

If you vomit after taking the study drugs, you should not take a replacement dose on that day. You should resume taking the study drugs at the next scheduled dose on the following day. If vomiting continues, you should tell your doctor.

You will be given a study drug diary to record the times that you take the study drugs and if you vomit. You should bring the diary to each study visit.

Study Visits:

At Week 1, your blood pressure will be measured.

At Week 2, your blood pressure will be measured and blood (about 1 teaspoon) will be drawn for routine tests.

At Week 4, you will have an EKG.

Every 4 weeks:

- You will have a physical exam.

- Blood (about 2 teaspoons) will be drawn for routine and biomarker testing.

- Urine will be collected to check your kidney function.

Every 8 weeks:

- You will have a neurological exam.

- Blood (about 1 teaspoon) will be drawn to check thyroid function.

- You will have an EKG.

If you are in Group A, you will have a brain MRI or CT scan at Week 4 of Cycle 2, and then every other cycle after that (Cycles 4, 6, 8 and so on) to check the status of the disease. You will also complete the symptom questionnaire at these visits.

If you are in Group B, you will have a brain MRI or CT scan at Week 4 of Cycles 1, 2, 3, and then every other cycle after that (Cycles 5, 7, 9 and so on) to check the status of the disease. You will also complete the symptom questionnaire at these visits.

At any time during the study, extra tests may be performed if the doctor thinks they are needed for your safety. The study doctor will tell you more about any extra tests.

End-of-Treatment Visit:

Within 14 days after your last dose of the study drugs, you will have an end-of-treatment visit. The following tests and procedures will be performed:

- You will have a physical exam.

- Blood (about 2 teaspoons) will be drawn for routine and biomarker testing. This blood draw will also include a pregnancy test if you can become pregnant.

Length of Treatment:

You may take the study drugs for up to 1 year. You will no longer be able to take the study drugs if the disease gets worse, if intolerable side effects occur, or if you are unable to follow study directions.

Your participation on the study will be over after the long-term follow-up phone calls.

Long-Term Follow-Up Calls:

After you have stopped taking the study drugs and completed your end-of-treatment visit, the study staff will call you 1 time every 3 months from then on to check on how you are doing. Each phone call should last about 5 minutes.

This is an investigational study. Pazopanib is FDA approved and commercially available for the treatment of renal cell cancer. Topotecan is FDA approved and commercially available for the treatment of lung cancer. In this study, the combination of pazopanib and topotecan is being used for research purposes only.

Up to 66 participants will be enrolled in this multicenter study. Up to 15 will take part at MD Anderson.
Criteria for eligibility
Healthy Volunteers: No
Maximum Age: N/A
Minimum Age: 18 Years
Gender: Both
Criteria: Inclusion Criteria:

1. Patients with histologically proven intracranial glioblastoma multiforme (GBM) or gliosarcoma (GS). Patients will be eligible if the original histology was low-grade glioma and a subsequent histological diagnosis of a GBM or GS is made. Patients must have evidence of progression of the GBM or GS on MRI or CT scan.

2. Patient must have failed prior chemoradiation with temozolomide and any other therapies except BEV (group A), or must have failed primary chemoradiation and a BEV-incorporating treatment (group B).

3. Patients may have had treatment for no more than 2 prior relapses. Relapse is defined as progression following initial therapy (i.e. radiation+/- chemo if that was used as initial therapy). The intent therefore is that patients had no more than 3 prior therapies (initial and treatment for 2 relapses). If the patient had a surgical resection for relapsed disease and no anti-cancer therapy was instituted for up to 12 weeks, and the patient undergoes another surgical resection, this is considered as 1 relapse. For patients who had prior therapy for a low-grade glioma, the surgical diagnosis of a high-grade glioma will be considered the first relapse

4. Patients must be greater than 12 weeks following completion of chemoradiation or any additional radiation to reduce the chance of pseudoprogression.

5. Measurable disease is required unless patient is post-operative and in that case patient can have no evidence of disease.

6. All patients must sign an informed consent indicating that they are aware of the investigational nature of this study. Patients must have signed an authorization for the release of their protected health information. Patients must be registered in the MD ANDERSON CANCER CENTER Office of Multicenter Clinical Research (OMCR) database prior to treatment with study drugs.

7. Archived tumor tissue must be available for all subjects for biomarker analysis and confirmation of the diagnosis before or during treatment. Samples must be provided within 4 weeks of enrollment.

8. Tissue to be analyzed for MGMT (if not already performed) and additional analyses noted in correlative biomarker section.

9. Patients must be >/= 18 years old.

10. Patients must have a Karnofsky performance status of >/= 60.

11. At the time of registration: Patients must have recovered from the toxic effects of prior therapy: >/= 28 days from any investigational agent, >/=28 days from prior cytotoxic therapy, >/=14 days from vincristine, >/=42 days from nitrosoureas, >/=21 days from procarbazine administration, >21 days from bevacizumab administration and >/=7 days for non-cytotoxic agents, e.g., interferon, tamoxifen, thalidomide, cis-retinoic acid, etc. (radiosensitizer does not count). Any questions related to the definition of non-cytotoxic agents should be directed to the Study Chair.

12. Patients must have adequate organ function: 1) Bone marrow function (WBC >/=3,000/µl, ANC >/=1,500/mm3, platelet count of >/=100,000/mm3, and hemoglobin >/=10 gm/dl). Eligibility level for hemoglobin may be reached by transfusion. 2) Liver function (alanine amino transferase (ALT) and aspartate aminotransferase (AST) <2.5XULN(upper limit of normal), and total bilirubin <1.5XULN), prothrombin time (PT) or international normalized ratio (INR), and activated partial thromboplastin time (aPTT) 1.5mg/dL, calculated creatinine clearance >/=50cc/min), and urine protein to creatinine ratio of <1 prior to registration. 4) These tests must be performed within 14 days prior to registration.

13. Patients must have shown unequivocal radiographic evidence for tumor progression by MRI or CT scan. A scan should be performed within 14 days prior to registration and on a steroid dose that has been stable or decreasing for at least 5 days. If the steroid dose is increased between the date of imaging and registration a new baseline MR/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.

14. Patients having undergone recent resection of recurrent or progressive tumor will be eligible as long as all of the following conditions apply: 1) They have recovered from the effects of surgery and be > 28 days from surgery. 2) Residual disease following resection of recurrent GBM or GS is not mandated for eligibility into the study. To best assess the extent of residual disease post-operatively, a CT/ MRI should be done no later than 96 hours in the immediate post-operative period or at least 4 weeks post-operatively, within 14 days prior to registration. If the 96-hour scan is more than 14 days before registration, the scan needs to be repeated. If the steroid dose is increased between the date of imaging and registration, a new baseline MRI/CT is required on a stable steroid dosage for at least 5 days.

15. Patients must have failed prior radiation therapy and must have an interval of greater than or equal to 12 weeks from the completion of radiation therapy to study entry.

16. Patients with prior therapy that included interstitial brachytherapy or stereotactic radiosurgery must have confirmation of true progressive disease rather than radiation necrosis based upon either PET or Thallium scanning, MR spectroscopy or surgical/pathological documentation of disease.
