Eligibility


INCLUSION CRITERIA:

Histologic diagnosis:

   - Patients with recurrent/progressive high-grade gliomas, as defined by progressive
   neurologic abnormalities or worsening neurologic status not explained by causes
   unrelated to tumor progression (e.g., anticonvulsant or corticosteroid wean,
   electrolyte disturbances, sepsis, hyperglycemia, etc.), OR a ≥ 25% increase in the
   bi-dimensional measurement, taking as a reference the smallest disease measurement
   recorded since diagnosis utilizing the MRI sequence best demonstrating tumor, OR the
   appearance of a new/metastatic tumor lesion(s) since diagnosis.

   - Eligible diagnoses include but are not limited to the following: diffuse intrinsic
   pontine glioma (DIPG), H3K27M-altered diffuse midline glioma (DMG), glioblastoma
   multiforme, anaplastic astrocytoma and anaplastic oligodendroglioma. Spinal cord
   tumors are eligible with pathologic confirmation of the above.

   - Please note: Patients with a radiographically typical DIPG at diagnosis, defined as a
   tumor with a pontine epicenter and diffuse involvement of more than 2/3 of the pons,
   are eligible without histologic confirmation.

   - Patients with pontine lesions that do not meet these radiographic criteria will be
   eligible if there is histologic confirmation of pontine glioma WHO II-IV.

   - Patients with diffuse or multi-focal disease are eligible; patients with
   leptomeningeal spread are eligible.

   immunotherapies with a known potential for pseudoprogression and who have assumed
   tumor progression must be at least 12 weeks from prior immunotherapy AND have at least
   two MRI scans at least 4 weeks apart demonstrating further progression OR have a
   biopsy to confirm tumor progression OR have new site(s) of disease.

   with the study procedures or results.

   - Patients with any other current malignancy.

   - Patients with uncontrolled hypertension (i.e., a blood pressure (BP) > 95th percentile
   for age, height, and gender; patients with values above these levels must have their
   blood pressure controlled with medication prior to starting study drug).

      - The normal blood pressure by height, age, and gender tables can be accessed in
      the Generic Forms section of the PBTC member's webpage.

Prisoners

   - Prisoners will be excluded from this study.

Inability to participate

   - Patients who in the opinion of the investigator are unwilling or unable to return for

   restrictions.

Allergy

   - Patients with a history of allergic reactions attributed to compounds of similar
   chemical or biologic composition.

   - Patients with a history of allergy to pork products due to contraindications with low

Thrombosis Risk

   - Patients with a known coagulopathy or bleeding disorder (e.g., von Willebrands
   disease) are not eligible.

   - Patients with a history of non-central line related thrombosis or disorders that
   promote clotting (e.g., anti-thrombin III deficiency, Lupus anticoagulant) are not
   eligible.

   - Significant family history of thrombosis (i.e. deep venous thrombosis or pulmonary
   embolus) in a first-degree relatives (i.e., parents or siblings) are not eligible.
