Trial Information

A Phase II Trial of Temozolomide Plus Bevacizumab in Patients With Metastatic Melanoma Involving the Central Nervous System

This study proposes the use of a combination of temozolomide and bevacizumab in a carefully
selected group of patients with metastatic melanoma to the brain. This combination has been
tested in primary brain tumors and in melanoma not involving the brain. The 6-week on,
2-week off low-dose schedule proposed in this trial capitalizes on preclinical data
demonstrating that temozolomide inhibits angiogenesis at low, non-toxic doses that
correspond to the plasma concentrations achieved by an oral administration, a so-called
'metronomic' scheduling. The precise mechanism of its antiangiogenic action remains to be
elucidated. This potential synergistic mechanism, together with the bulk of evidence for
activity presented above suggests that the combination will be well-tolerated, safe and
possibly more effective.

Inclusion Criteria:

1. Patients must have histologically or cytologically confirmed malignant melanoma and
clinical evidence of metastatic disease to the brain. Mucosal and ocular melanomas
are included.

2. Untreated asymptomatic brain metastases ≤ 2 cm in maximal diameter, with mild or
minimal edema, without associated hemorrhage or midline shift.

3. Progressing brain metastases of any size, not amenable to surgical resection and/or
progressing through radiation therapy but without evidence of active associated
hemorrhage. Treatment with bevacizumab may not be initiated until 4 weeks after
surgical resection or radiation therapy completion.

4. Hemorrhagic metastases that have resolved after previous resection or radiation
therapy do not exclude patients with new non-hemorrhagic metastases meeting the
criteria described above from participating.

5. Patients must have measurable metastases to the brain, defined as at least one lesion
that can be accurately measured in at least one dimension (longest diameter to be
recorded) as >10 mm in the brain MRI with gadolinium. For disease outside the brain,
tumors must be > 20 mm with conventional techniques or > 10 mm with spiral CT scan.
Measurable disease outside the brain is NOT required.

6. Patients with any number of previous systemic therapies are eligible. Previous
temozolomide treatment given on a different schedule is allowed, as long as it had
not been given in combination with VEGF-targeting drugs.

7. Age > 18 years. Because no dosing or adverse event data are currently available on
the use of bevacizumab in patients <18 years of age, children are excluded from this

8. Life expectancy of 8 weeks or greater.

9. ECOG performance status < 2 (Karnofsky > 60%).

10. Patients must have normal organ and marrow function as defined below:

- Leukocytes > 3,000/µl

- Absolute neutrophil count > 1,500/µl

- Platelets > 100,000/µl

- Total Bilirubin ** Within institutional upper limit of normal

- AST(SGOT)/ALT(SGPT) < 2.5 X institutional upper limit of normal

- Creatinine* Within institutional upper limit of normal*

- If creatinine > upper limit of normal, a creatinine clearance >/= 60 ml/m2
is required

- Except for patients with known Gilbert's syndrome

11. The effects of bevacizumab on the developing human fetus at the recommended
therapeutic dose are unknown. For this reason and because the anti-angiogenic agent
used in this trial may be teratogenic, women of child-bearing potential and men must
agree to use adequate contraception (hormonal or barrier method of birth control)
prior to study entry and for the duration of study participation. Should a woman
become pregnant or suspect she is pregnant while participating in this study, she
should inform her treating physician immediately.

12. Concomitant use of steroids to treat cerebral edema is allowed.

13. Ability to understand and the willingness to sign a written informed consent

Exclusion Criteria:

- Disease-Specific Exclusions Patients with metastatic disease to the brain not fitting
the inclusion criteria. Patients with leptomeningeal disease are not excluded.

- General Medical Exclusions

Subjects meeting any of the following criteria are ineligible for study entry:

1. Inability to comply with study and/or follow-up procedures.

2. Life expectancy of less than 8 weeks

3. Current, recent (within 4 weeks of the first infusion of this study), or planned
participation in an experimental drug study other than this study.

4. History of allergic reactions attributed to compounds of similar chemical or biologic
composition to bevacizumab or temozolomide.

5. Patients must not exhibit any clinical evidence of coagulopathy. The INR must be <
1.5 and the values for PTT must be within normal limits. Anticoagulation is not

6. Uncontrolled intercurrent illness including, but not limited to, ongoing or active
infection, symptomatic congestive heart failure, unstable angina pectoris, untreated
cardiac arrhythmia, or psychiatric illness/social situations that would limit
compliance with study requirements.

7. Pregnant women are excluded from this study because bevacizumab is an agent with the
potential for teratogenic or abortifacient effects. Because there is an unknown but
potential risk for adverse events in nursing infants secondary to treatment of the
mother with bevacizumab, breastfeeding should be discontinued if the mother is
treated with bevacizumab. These potential risks may also apply to other agents used
in this study.

8. Otherwise well HIV-positive patients will be permitted to enroll on this trial.

Bevacizumab-Specific Exclusions

1. Previous treatment with bevacizumab.

2. Inadequately controlled hypertension (defined as systolic blood pressure 150 and/or
diastolic blood pressure > 100 mmHg on antihypertensive medications)

3. Any prior history of hypertensive crisis or hypertensive encephalopathy

4. New York Heart Association (NYHA) Grade II or greater congestive heart failure (see
Appendix E)

5. History of myocardial infarction or unstable angina within 6 months prior to study

6. History of stroke or transient ischemic attack within 6 months prior to study

7. Significant vascular disease (e.g., aortic aneurysm, aortic dissection)

8. Symptomatic peripheral vascular disease

9. Evidence of bleeding diathesis or coagulopathy

10. Major surgical procedure, open biopsy, or significant traumatic injury within 28 days
prior to study enrollment or anticipation of need for major surgical procedure during
the course of the study

11. Core biopsy or other minor surgical procedure, excluding placement of a vascular
access device, within 7 days prior to study enrollment

12. History of abdominal fistula, gastrointestinal perforation, or intra-abdominal
abscess within 6 months prior to study enrollment

13. Serious, non-healing wound, ulcer, or bone fracture

14. Proteinuria at screening as demonstrated by either

- Urine protein:creatinine (UPC) ratio 1.0 at screening OR

- Urine dipstick for proteinuria ≥ 2+ (patients discovered to have ≥2+ proteinuria
on dipstick urinalysis at baseline should undergo a 24 hour urine collection and
must demonstrate ≤ 1g of protein in 24 hours to be eligible).
