Study Description

Brief Summary:

The goal of this interventional study is to evaluate the efficacy of APG-157 in combination with Bevacizumab in subjects with recurrent high-grade glioma. The main questions the study aims to answer are:

• Progression-free and overall survival of patients receiving this combination;
• Quality of Life (QOL); and
• Tumor response on imaging

The participants will take APG-157 daily by dissolving two pastilles in their mouth at around breakfast, lunch and dinner time (total of six pastilles per day). The pastilles dissolve in the mouth.

The participants will continue to receive Bevacizumab as standard of care.

Condition or disease	Intervention/treatment	Phase
Glioma; Glioblastoma Multiforme	Drug: APG-157	Phase 1; Phase 2

Detailed Description:

The goal of this interventional study is to evaluate the efficacy of APG-157 in combination with Bevacizumab in subjects with recurrent high-grade glioma who have previously progressed on bevacizumab alone. The main questions the study aims to answer are:

• Progression-free and overall survival of patients receiving this combination;
• Quality of Life (QOL); and
• Tumor response on imaging

Additional aims include:

• characterization of pharmacokinetics (PK) of APG-157 in the presence of bevacizumab; and
• optionally serum changes in VEGF and HIF-1 alpha, if the study shows preliminary indication of efficacy

The participants will take APG-157 daily by dissolving two pastilles in their mouth at around breakfast, lunch and dinner time (total of 6 pastilles per day). The pastilles dissolve in the mouth.

The participants will continue to receive Bevacizumab and be present for scheduled visits and examinations as standard of care.

Outcome Measures

Primary Outcome Measures :

1. Progression-free Survival [ Time Frame: From date of commencement of treatment until the date of first documented progression or date of death from any cause, whichever comes first, assessed up to 12 months ]
   To evaluate progression-free survival of participants with recurrent high-grade glioma treated with APG-157 and Bevacizumab. Progression of the disease will be assessed using commonly used imaging modality such as Magnetic Resonance Imaging or CT scan.
2. Overall Survival [ Time Frame: From date of commencement of treatment until the date of death from any cause. Duration of assessment will be 12 months from the date of commencement of the treatment. ]
   To evaluate overall survival of participants with recurrent high-grade glioma treated with APG-157 and Bevacizumab

Secondary Outcome Measures :

1. QOL assessment (EORTC QLQ-C30) [ Time Frame: Every 8 weeks; from date of commencement of treatment until the date of first documented progression or date of death from any cause, whichever comes first, assessed up to 12 months ]
   Descriptively examine quality of life (QOL) using EORTC QLQ-C30 (Organization for Research and Treatment in Cancer Quality of Life Questionnaire C30). EORTC QLQ-C30 is a standardized questionnaire that rates function, symptoms and health status from patient perspective using various questions on a scale of 1 - 4 where generally 1 is rated as normal or no issue (not at all) and 4 being the maximum adverse impact being experienced (very much).
2. Radiographic studies MRI or CT of the brain [ Time Frame: Every 8 weeks; from date of commencement of treatment until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 12 months ]
   To measure tumor size in response to treatment
3. Pharmacokinetics (PK) of APG-157 [ Time Frame: At three timepoints: at start of dosing; at end of cycle 1 (each cycle is 28 days); and at end of cycle 2 after start of dosing. ]
   Measure the amount of APG-157 components in the blood in the presence of bevacizumab

Eligibility Criteria

• Ages Eligible for Study: 19 Years and older (Adult, Older Adult)
• Sexes Eligible for Study: All
• Accepts Healthy Volunteers: No

Criteria

Inclusion Criteria:

1. Patients must have pathologically proven diagnosis of high grade (aka grade III or IV) glioma that has progressed on bevacizumab (anaplastic astrocytoma, anaplastic oligodendroglioma, glioblastoma, gliosarcoma, H3K27M mutant glioma).
2. Patients must have received prior radiation therapy and standard temozolomide. Patients who have received any number of therapies for previous progressions will be considered eligible.
3. Patients must be three or more months from the end of chemoradiotherapy or have biopsy or imaging consistent with disease progression.
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.
7. Patients must have an adequate bone marrow reserve (ANC count ≥1,500/mm3, hemoglobin > 8 g/dL, platelet count ≥100,000/mm3).

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.

   • Myocardial infarction or unstable angina within 6 months
6.

Note: Patients with full-dose anticoagulants are eligible provided the patient has been on a stable dose for at least 2 weeks
7. Active wound, a serious or non-healing wound, an active ulcer or untreated bone fracture.
