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

August 8, 2024 updated by: Guido A. Davidzon, MD, SM

A Phase I Study of [18F]DASA-23 as a PET Tracer for Evaluating Pyruvate Kinase M2 (PKM2) Expression in Healthy Volunteers and in Patients With Intracranial Tumors

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.

Study Overview

Detailed Description

PRIMARY OBJECTIVES:

I. Determine whether the fluorine F 18 DASA-23 ([18F]DASA 23) PET scan signal change from pre-therapy to one week after initiation of therapy can predict the tumor's responsiveness to therapy and 6 month progression free survival (PFS6), in suspected recurrent glioblastoma.

SECONDARY OBJECTIVES:

I. Determine the sensitivity, specificity, and accuracy of [18F]DASA-23 PET imaging in identifying intracranial tumors in patients with intracranial tumors.

II. Determine whether the [18F]DASA-23 PET scan signal change from pre therapy to one week after initiation of therapy can predict progression free survival (PFS) and overall survival (OS), in suspected recurrent glioblastoma.

OUTLINE: Participants are assigned to 1 of 4 groups.

GROUP I: Healthy volunteers receive [18F]DASA-23 intravenously (IV) and undergo brain PET scan over 15 minutes and 4 vertex-to-toe PET scans over 30 minutes each.

GROUP II: Intracranial tumor participants receive [18F]DASA-23 IV and undergo brain PET scan over 60 minutes and 1 vertex-to-toe PET scan over 30 minutes.

GROUP III: Subjects with glioblastoma will receive [18F]DASA-23 IV and undergo brain PET scan over 60 minutes and 1 vertex-to-toe PET scan over 30 minutes. 15-minute vertex-to-thigh PET for Part 3 patients, Participants undergo second PET scan 7 days after the initiation of therapy.

GROUP IV: Healthy volunteers will undergo the same procedures as the healthy volunteers in Group I with the following exceptions:

Group IV healthy volunteers will undergo a 60-minute PET/MRI brain scan instead of a 15-minute PET/MRI brain scan.

Group IV healthy volunteers will not undergo any vertex-to-toe PET scans.

After completion of study treatment, intracranial tumor and recurrent glioblastoma participants are followed up every 3 months for 12 months.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in [18F]DASA-23 PET scan signal in patients with suspected recurrent glioblastoma
Time Frame: From pre-treatment to one week after initiation of treatment
Response to treatment is based on the response assessment in neuro-oncology (RANO) criteria. Each patient will be dichotomized into responding (yes) or not responding (no) to treatment based on RANO criteria. The [18F]DASA-23 PET scan signal will be calculated according to the European Organization for Research and Treatment of Cancer (EORTC) response criteria guidelines and reported as median and range, both for the entire cohort as well as separately for the responder and non-responder subgroups. The Mann-Whitney test of [18F]DASA-23 PET scan signal between responders and non-responders will be performed.
From pre-treatment to one week after initiation of treatment

Patients will be divided into two groups based on whether their percent change in SUV is above or below the median. Kaplan-Meier curves for the two groups will be plotted and a log-rank test for difference in progression-free survival will be performed. A Cox proportional-hazards regression of progression-free survival on group will be performed. Progression-free survival will be reported as median survival time, with range.
