4. Physiologic Status/Age: Patients must be 19 years of age or older (the age of consent in Nebraska.)

5. Patients must have recovered from any toxicity of prior therapy to Grade 1 or less.

6. ECOG Performance Status of 0-3.

8. Patients must have adequate renal and hepatic function with:

   1. creatinine < 1.5 x institutional upper limit of normal (ULN).
   2. total bilirubin < 1.5 x ULN (unless due to Gilbert's disease)
   3. aspartate aminotransferase (AST) or alanine aminotransferase (ALT) <2.5 x ULN
   4. serum alkaline phosphatase less than 2.5 times the upper limits of normal)

9. The patient must willingly provide written, informed consent after being informed of the procedure to be followed, the experimental nature of the therapy, alternatives, potential benefits, side-effects, risks, and discomforts.

Exclusion Criteria:

1. Any life-threatening illness, medical condition, or organ system dysfunction which, in the investigator's opinion, could compromise the subject's safety, interfere with the absorption or metabolism of oral APG-157, or put the study outcomes at undue risk

2. Immunotherapy, chemotherapy, radiotherapy, or experimental therapy within one full cycle period before first dose of study drug (i.e., for lomustine 6 weeks, for temozolomide 4 weeks)

3. Lactating or pregnant

4. History of uncontrollable allergic reactions to bevacizumab

5. Clinically Significant Cardiovascular Disease Defined as follows:

   • Inadequately controlled hypertension (i.e., systolic blood pressure (SBP) > 160 mm Hg and/or diastolic blood pressure (DBP) > 90 mm Hg despite antihypertensive therapy)
   • History of cerebrovascular accident (CVA) within 6 months
   • Myocardial infarction or unstable angina within 6 months

6. Evidence or history of bleeding diathesis (greater than normal risk of bleeding, i.e., Hereditary Hemorrhagic Telangiectasia type I or HHT-1) or coagulopathy in the absence of therapeutic anti-coagulation or any hemorrhage/bleeding event > Grade 3 within 4 weeks prior to registration. Note: Patients with full-dose anticoagulants are eligible provided the patient has been on a stable dose for at least 2 weeks
