NCT06672575

Brief Summary

The goal of Phase 1 of this clinical research study is to find the highest tolerable dose and the recommended Phase 2 dose of ivonescimab that can be given to patients who have recurrent glioblastoma. The goal of Phase 2 of this clinical research study is to learn if the recommended Phase 2 dose of ivonescimab found in Phase 1 can help to control the disease.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age ≥18 years
  • Karnofsky Performance Status (KPS) of 60 or greater
  • Recurrent supratentorial Glioblastoma that has progressed following standard therapy; patients must have previously been treated with radiation with or without temozolomide.
  • Patients will be eligible at first or second recurrence.
  • Patients must be greater than 12 weeks from completion of initial chemoradiation at the time of progression, with the exception that patients with biopsy-confirmed recurrent disease prior to this time window can be enrolled.
  • Diagnosis of Glioblastoma IDH-wildtype, WHO Grade 4 consistent with WHO CNS 2021 criteria. This will include patients with a diagnosis of molecular glioblastoma.
  • Measurable or evaluable disease per RANO criteria
  • A baseline MRI Brain no more than 14 days prior to study enrollment
  • Adequate Organ Function, with screening labs performed within 14 days of treatment initiation:
  • a. Hematology (no blood transfusions or growth factor therapy used within 7 days of the screening CBC): i. Absolute neutrophil count (ANC) ≥ 1.5 × 109/L ii. Platelet count ≥ 100 × 109/L iii. Hemoglobin ≥ 9.0 g/dL b. Kidneys: i. Creatinine clearance\* (CrCL) ≥ 50 mL/min using the Cockcroft-Gault formula or estimated glomerular filtration rate (eGFR) value ≥50 mL/min using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation (adjustment by BSA is not required for eGFR)
  • CrCL or eGFR can be determined using the calculator from the National Kidney Foundation website (www.kidney.org).
  • ii. Urine protein \< 2+ or 24-hour urine protein quantification \< 1.0 g or Urine protein/Creatinine ratio ≤ 1mg/mg (≤ 113.2mg/mmol) c. Liver: i. Serum total bilirubin (TBIL) ≤ 1.5 × upper limit of normal (ULN); For patients with confirmed/suspected Gilbert syndrome, TBIL ≤3 × ULN ii. Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 2.5 × ULN d. Coagulation: prothrombin time (PT) or international normalized ratio (INR)
  • × ULN, and partial prothrombin time (PTT) or activated partial thromboplastin time (aPTT) ≤ 1.5 × ULN (unless abnormalities are unrelated to coagulopathy or prophylactic coagulation)
  • Female patients of childbearing age must have negative serum pregnancy test results before randomization or per region-specific guidance documented in the informed consent and a negative urine pregnancy test on the day of first dose prior to dosing.
  • Female patient of childbearing potential having sex with an unsterilized male partner must agree to use a highly effective method of contraception from the beginning of screening until 120 days after the last dose of the ivonescimab.
  • +4 more criteria

You may not qualify if:

  • Major surgical procedures or serious trauma, or plans for major surgical procedures within 4 weeks after the first dose (as determined by the investigator).
  • Minor local procedures (excluding central venous catheterization and port implantation).
  • Currently pregnant or breastfeeding.
  • History of bleeding tendencies or coagulopathy and/or clinically significant bleeding symptoms, including but not limited to:
  • a. Significant intracranial hemorrhage
  • Note: Patients with clinically asymptomatic presence of hemosiderin, resolving postoperative changes or punctate intratumoral hemorrhage are permitted
  • Gastrointestinal bleeding
  • b. Hemoptysis (defined as coughing up ≥ 0.5 teaspoon of fresh blood or small blood clots) Note: transient hemoptysis associated with diagnostic bronchoscopy is allowed. c. Nasal bleeding /epistaxis (bloody nasal discharge is allowed) d. Need for therapeutic anticoagulant therapy Note: Prophylactic anticoagulation for DVT/PE or to maintain venous patency is allowed.
  • Current hypertension with systolic blood pressure ≥ 150 mmHg or diastolic blood pressure ≥ 100 mmHg after oral antihypertensive therapy
  • Is receiving dexamethasone \>2mg daily, or the corticosteroid equivalent thereof.
  • History of major diseases, specifically:
  • Unstable angina, myocardial infarction, congestive heart failure (New York Heart Association \[NYHA\] classification ≥ grade 2) or vascular disease (eg, aortic aneurysm at risk of rupture), or other cardiac impairment that may affect the safety evaluation of the study drug (eg, poorly controlled arrhythmias, myocardial ischemia)
  • History of esophageal gastric varices, severe ulcers, wounds that do not heal, abdominal fistula, intra-abdominal abscesses, or acute gastrointestinal bleeding
  • History of arterial thromboembolic event, venous thromboembolic event of Grade 3 and above as specified in National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) 5.0, transient ischemic attack, cerebrovascular accident, hypertensive crisis, or hypertensive encephalopathy
  • Acute exacerbation of chronic obstructive pulmonary disease within 4 weeks beforerandomization
  • +15 more criteria
