participant entry

- Age ? 18 years.

- Karnofsky ? 70%

Participants must have histologically confirmed diagnosis of GBM patients with either
grade III or IV malignant glioma are eligible to the Phase I portion of the study)
and radiographic evidence of recurrence or disease progression (defined as either a
greater than 25% increase in the largest bidimensional product of enhancement, a new
enhancing lesion, or significant increase in T2 FLAIR) following prior therapy (i.e.
chemotherapy, XRT, other investigational therapies).

- No more than 2 prior episodes of progressive disease (patients with more than 2 prior
episodes of progressive disease are eligible for the Cohort B, Phase I portion of
this study)

- An interval of at least 4 weeks (to start of study agent) between prior surgical
resection or one week from stereotactic biopsy

- An interval of at least 12 weeks (to start of study agent) from the end of prior
radiotherapy unless there is a new area of enhancement consistent with recurrent
tumor outside of the radiation field, or there is histological confirmation of
unequivocal tumor progression

- From the projected start of scheduled study treatment, the following time periods
must have relapsed: 4 weeks (or 5 half lives, whichever is shorter) from any
investigational agent, 4 weeks (or 5 half lives, whichever is shorter) from cytotoxic
therapy (except 23 days for temozolomide and 6 weeks from nitrosoureas), 6 weeks
from antibodies (or 5 half lives, whichever is shorter), or 4 weeks (or 5 half lives,
whichever is shorter) from other anti?tumor therapies.

- Participants must have recovered to a grade 0 or 1 from the toxic effects of prior
therapy (with the exception of lymphopenia, which is common after therapy with
temozolomide, and alopecia).

OR per 24 hour urine collection

- Urinary protein quantitative value of < 30 mg/dL in urinalysis or <1+ on dipstick,
unless quantitative protein is < 1000 mg in a 24 hour urine sample;

salpingo?oophorectomy and are sexually active must consent to use an accepted and
highly effective non?hormonal method of contraception (i.e. double barrier method

Exclusion Criteria:

- Prior AMG 386 therapy or other molecules that inhibit the angiopoietins or Tie2

- Co-medication that may interfere with study results; e.g. immunosuppressive agents
other than corticosteroids.

- Active infection requiring intravenous antibiotics

- Current or within 30 days prior to enrollment treatment with immune modulators such
as systemic cyclosporine and tacrolimus.

- Current us of warfarin sodium or any other Coumadin?derivative anticoagulant.
Participant must be off Coumadin?derivative anticoagulants for at least seven days
prior to starting study drug. ow molecular weight heparin is allowed.

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

- Herbal preparations/medications are not allowed throughout the study. These herbal
medications include, but are not limited to: St. John's wort, Kava, ephedra (ma
huang), gingko biloba, dehydroepiandrosterone (DHEA), yohimbe, saw palmetto, ginseng.
Participants should stop using any herbal medications 7 days prior to first dose of
study drug.

diastolic blood pressure > 90 mmHg). The use of anti?hypertensive medications to
control hypertension is permitted.
