[18F]DASA-23 and PET Scan in Evaluating Pyruvate Kinase M2 Expression in Patients With Intracranial Tumors or Recurrent Glioblastoma and Healthy Volunteers

Summary

This phase I trial studies how well \[18F\]DASA-23 and positron emission tomography (PET) scan work in evaluating pyruvate kinase M2 (PKM2) expression in patients with intracranial tumors or recurrent glioblastoma and healthy volunteers. PKM2 regulates brain tumor metabolism, a key factor in glioblastoma growth. \[18F\]DASA-23 is a radioactive substance with the ability to monitor PKM2 activity. A PET scan is a procedure in which a small amount of a radioactive substance, such as \[18F\]DASA-23, is injected into a vein, and a scanner is used to make detailed, computerized pictures of areas inside the body where the substance is used. Tumor cells usually pick up more of these radioactive substances, allowing them to be found. Giving \[18F\]DASA-23 with a PET scan may help doctors evaluate PKM2 expression in healthy volunteers and in participants with intracranial tumors or recurrent glioblastoma.
