About
This phase II trial compares the effect of GI-102 alone and in combination with pembrolizumab given before surgery in treating patients with IDH wildtype glioblastoma and IDH mutated grade 4 astrocytoma that has come back after a period of improvement (recurrent) or that is growing, spreading, or getting worse (progressive). Glioblastoma is the most common and the most aggressive primary brain tumor in adults. Current standard of care includes surgical resection, radiation and chemotherapy. Treatment is often given before surgery (neoadjuvant therapy) to shrink the tumor and make it easier to remove. Treatment with GI-102, a bispecific fusion protein, may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the tumor, and may interfere with the ability of tumor cells to grow and spread. Giving GI-102 alone and in combination with pembrolizumab between neoadjuvant therapy and surgery may be safe, tolerable, and effective in treating patients with recurrent or progressive IDH wildtype glioblastoma and IDH mutated grade 4 astrocytoma.

- Pregnant persons
- Nursing persons
- Persons of childbearing potential or able to father a child who are unwilling to employ adequate contraception
-

-
Uncontrolled intercurrent illness including, but not limited to:
- Ongoing or active infection requiring IV antibiotics
- Symptomatic congestive heart failure
- Unstable angina pectoris
- Cardiac arrhythmia
- Or psychiatric illness/social situations (e.g., drug addiction) that would limit compliance with study requirements
-
Receiving any other investigational agent at the time of registration
-
History of myocardial infarction ≤ 6 months, or congestive heart failure requiring use of ongoing maintenance therapy for life-threatening ventricular arrhythmias
-

Note: No testing for hepatitis B and hepatitis C is required unless mandated by local health authority
-
NOTE: Patients with known hepatitis B OR hepatitis C may be enrolled if they meet the following criteria:
- Hepatitis B: Patients who are HBsAG positive are eligible if they have received HBV antiviral therapy for at least 4 weeks and have undetectable HBV viral load prior to randomization. Patients should remain on anti-viral therapy throughout the treatment phase of the trial and should follow local guidelines for HBV anti-viral therapy after completing study treatment
