Panitumumab-IRDye800 in Diagnosing Participants With Malignant Glioma Undergoing Surgery

Summary

The phase I/II trial studies the side effects and best dose of panitumumab-IRDye800 in diagnosing participants with malignant glioma who undergo surgery. Panitumumab-IRDye800 can attach to tumor cells and make them more visible using a special camera during surgery, which may help surgeons better distinguish tumor cells from normal brain tissue and identify small tumors that cannot be seen using current imaging methods.

Interventions

• Near-Infrared Fluorescence Imaging · PROCEDURE

  Undergo NIR imaging

• Panitumumab · BIOLOGICAL

  Given IV

• Panitumumab-IRDye800 · DRUG

  Intraoperative camera capable of exciting and detecting near infrared (NIR) dyes. Imaging will be performed on subjects during surgery and/or on ex-vivo resected tissues in the surgery suite ("back table").

Published eligibility criteria

Verbatim from the registry. Only the site can decide how these apply to a specific patient.

Inclusion Criteria:

1\) One of the following:

1. Cohorts 1, 2, and 3: Participants with suspected or confirmed diagnosis of glioblastoma
2. Cohort 4: Participants with suspected or confirmed diagnosis of vestibular schwannoma

   2.) Planned surgical removal of the tumor as part of standard of care. This may include participants postchemotherapy, post-radiation, and/or participants who have undergone diagnostic biopsy for their original diagnosis and are felt to be candidates for resection.

   3\) Participant age ≥ 18 years.

   4\) Participants or their designated advocates must be willing to and capable of providing informed consent and willing and able to comply with all scheduled visits, treatment plan, laboratory tests, lifestyle considerations, and other study procedures.

Exclusion Criteria:

1. Received an investigational drug within 30 days prior to first dose of Panitumumab-IRDye800.
2. Myocardial infarction (MI); cerebrovascular accident (CVA); uncontrolled congestive heart failure (CHF); significant liver disease as determined by PI; or unstable angina within 6 months prior to enrollment.
3. History of infusion reactions to monoclonal antibody therapies
4. Pregnant or breastfeeding.
5. Evidence of QTc prolongation on pretreatment ECG (greater than 440 ms in males or greater than 460 ms in females).
6. Any of the following lab values:

   1. Platelet count \< 75,000/mm3
   2. TSH ≥ 13 micro International Units/mL.
   3. Magnesium, potassium, or calcium \< each respective upper limit of normal
   4. Serum creatinine \> 1.5 times upper limit of normal
7. Participants receiving Class IA (quinidine, procainamide) or Class III (dofetilide, amiodarone, sotalol) antiarrhythmic agents.
8. Participants with a history or evidence of interstitial pneumonitis or pulmonary fibrosis.
9. Participants not deemed by PI to be appropriate candidates for optimal resection of tumor based on location, involvement of eloquent brain, satellite lesions, or other factors not specifically listed here.
