简要总结
This is a single-arm, open-label study to assess the safety and effectiveness of a single dose of oral propranolol in reducing18F-fluorodeoxyglucose (FDG) uptake in brown adipose tissue (BAT) in pediatric oncology patients. This study is designed to better understand if taking a single dose of an oral medication called propranolol can reduce the chance of brown fat showing up on a PET scan, and therefore make the scan more accurate and easy to interpret. All humans have some degree of normal brown fat (called brown adipose tissue), and this normal tissue can sometimes light up on a PET scan. That creates problems because it may be wrongly interpreted by the radiologist as tumor, or it may hide true areas of tumor underneath it. Participants will not be randomized and will receive a single dose of oral propranolol approximately 60 minutes prior to the injection of the FDG tracer. The dose of propranolol will be 20 mg for all participants.
详细描述
In this study, participants will be assessed in the University of Kentucky DanceBlue Pediatric Hematology/Oncology clinic to confirm they are eligible for the study. This will be done at the time intravenous (iv) access is started, either through an iv placed in the arm or through a port/central line.
All females who are capable of becoming pregnant will then undergo urine pregnancy testing. If it is found that they are pregnant they will not be allowed to be in the study. Participant blood sugar will be checked. When possible, the research blood sample will be collected at a time when routine non-research labs will be collected.
Study eligible participants will then be given a single 20 mg tablet of propranolol to take by mouth and will be escorted by a member of the medical team to the PET scan trailer, where they will be checked in and assessed. Blood sugar level will again be checked by finger stick according to the standard procedure for PET scans.
Vital signs will be assessed by a clinical research nurse at least three times while the participants are at the PET scan trailer, including twice before the scan and once immediately after the scan. The nurse will also assess for any symptoms related to the propranolol. If no problems are noted, participants will be discharged from the PET scan trailer and their tudy participation will end. If any side effects arise from the medication, the pediatric oncologist will be called immediately and appropriate treatment started. The PET scan will be assessed by the radiologist to see whether there is uptake in brown fat, as well as to see if any areas of tumor are seen.
