A Pilot Study of Bevacizumab for Neoplastic Meningitis

A Pilot Study of Systemically Administered Bevacizumab in Patients With Neoplastic Meningitis (NM)

The goal of this clinical research study is to learn if and how Avastin (bevacizumab) may affect cancer that has spread to the meninges of the brain or the spinal cord. The safety of this drug will also be studied.

Objectives:

1. Primary:

1. Determine preliminary response data of intravenous bevacizumab in patients with NM

a. As measured by clearance of malignant cells from the Cerebrospinal fluid (CSF) at 2, 4, 6, 12, 18, and 24 weeks, then every 8 weeks up to 54 weeks, and

b. Time to neurological progression (TTNP)

2. Secondary:

1. Evaluate the safety of intravenous bevacizumab in patients with NM

2. Further describe the efficacy of this intervention as measured by

   1. improvement of MR imaging evidence of disease
   2. overall survival
   3. maintenance of quality of life
3. Determine effects of systemically administered bevacizumab on CSF, serum, and urine Vascular endothelial growth factor (VEGF)levels levels
4. Correlate changes in CSF VEGF with response measurements.
5. Correlate primary tumor tissue VEGF expression with CSF VEGF levels
6. Correlate urine VEGF levels with serum and CSF VEGF levels
7. Evaluate serum and CSF VEGF index

Study Overview

Detailed Description

The Study Drug:

Bevacizumab is designed to prevent or slow down the growth of cancer cells by blocking the growth of blood vessels.

Study Drug Administration:

If you are found to be eligible to take part in this study, every 2 weeks, you will receive bevacizumab by vein over about 1 hour.

Study Visits:

At Weeks 2 and 4:

• Samples of CSF from your spinal cord will be collected to check for the presence of cancer cells.
• Blood (about 3 tablespoons) will be drawn for routine tests and to check your blood's ability to clot normally.
• If you already have an Ommaya reservoir tap in place, samples of CSF from your brain will be collected to look for the presence of cancer cells.
• 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.

At Weeks 6, 12, 18, and 24, and then every 8 weeks:

• Samples of CSF from your spinal cord will be collected to check for the presence of cancer cells.
• Blood (about 3 tablespoons) will be drawn for routine tests and to check your blood's ability to clot normally.
• If you already have an Ommaya reservoir tap in place, samples of CSF from your brain will be collected to look for the presence of cancer cells.

Patients are receiving anticoagulation (warfarin or low molecular weight heparins (LMWH)) only if the patients can be off of warfarin for 4-5 days prior to the LP and placed on LMWH in that interim, and if the 'treatment dose' of LMWH can be safely held for 24 hours before and after the LP.
10. ( 9. continued) INR must be <1.2 prior to LP in this circumstance. If patients are receiving thromboprophylaxis dose of LMWH, the patients can be enrolled, but the thromboprophylaxis LMWH must be able to be safely held for 12 hours prior to the LP. 2. The patient has no active bleeding or pathological condition that carries a high risk of bleeding 3. There is no evidence of serious or non-healing wound, ulcer or bone fracture

2. Besides NM, other known CNS disease, except for treated brain metastases(Patients must be at least 1 month out from brain irradiation and have no evidence of progression or hemorrhage at that time, as ascertained by clinical examination and brain imaging (MRI or CT) during the screening period). Anticonvulsants (stable dose) are allowed. Treatment for brain metastases may include whole brain radiotherapy, radiosurgery or a combination as deemed appropriate by the treating physician.
3. (2. continued) With respect to irradiation for other purpose (for NM or bone metastases, etc) patients need only 1 week out from the completion of irradiation. Patients with CNS metastases treated by neurosurgical resection or brain biopsy performed within 3 months prior to Day 1 will be excluded.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Cerebrospinal Fluid (CSF) Response Rate: Percentage of Participants Positive for Tumor Cells	CSF response for participants with Neoplastic Meningitis (NM) or leptomeningeal disease (LMD) defined as conversion from positive to negative cytology or cytometry as measured routinely by total clearance of malignant cells from the CSF where assessments performed from 2 weeks up to week 54 of treatment. Clearance of malignant cells determined by standard clinical testing using cytospin analysis in clinical laboratory. Percentage reflects number of participants of total treated with no response, e.g. participants with continued positive CSF cytology or flow cytometry.	1 year (54 weeks) of treatment
Median Time to Progression (TTP) and Median Time to Neurological Progression (TTNP)	Time to Progression defined as time to disease progression measured from date of enrollment, confirmation of disease progression via laboratory testing; Time to neurological progression (TTNP) reflects worsening clinical signs/symptoms or development of new clinical signs/symptoms which investigator feels can be attributed to leptomeningeal disease progression and are severe enough to warrant a change in therapy.	6 weeks

Other Outcome Measures

Outcome Measure	Measure Description	Time Frame
Participant Response: Cerebrospinal Fluid (CSF) Examination	Neoplastic meningitis is considered an unmeasurable metastatic site by Response Evaluation Criteria in Solid Tumors (RECIST), and as such no standardized methodologies are routinely used; therefore response assessed from cerebrospinal fluid (CSF) obtained via lumbar puncture (and from ventricular reservoir if present) and analyzed for malignant cells along with reference recording of magnetic resonance imaging (MRI) of areas of enhancement over time; however, MRI alone in LMD/NM is considered non-evaluable by RECIST criteria. Those participants with only MRI criteria for enrollment, but who later develop CSF positivity after enrollment were declared "progressors" based on the CSF criteria.	1 year (54 weeks) of treatment
