Introduction to Fluorodopa F 18
Fluorodopa F 18, also known as 18F-FDOPA, is a radioactive diagnostic agent used in Positron Emission Tomography (PET) scans to visualize dopaminergic nerve terminals in the striatum of the brain. It is specifically indicated for the evaluation of adult patients with suspected Parkinsonian Syndromes (PS)[1][5].
Clinical Trials and Efficacy
The FDA approved Fluorodopa F 18 based on evidence from a single clinical trial involving 56 patients with suspected Parkinsonian Syndromes. Here are the key points from the trial:
- Trial Design: The trial was a prospective single-arm study conducted at a single center. Patients received a single intravenous dose of Fluorodopa F 18 before undergoing a PET scan. The imaging results were compared to a reference clinical diagnostic standard established 6 to 9 months after the scan[1][5].
- Efficacy Results: The primary outcome was the positive and negative percent agreement of the PET image results with the clinical diagnostic standard. The results showed varying degrees of agreement among three readers, with positive percent agreements ranging from 49% to 73% and negative percent agreements ranging from 83% to 91%[1].
- Demographics: The trial included both men and women, and the drug worked similarly across different age groups. However, data on racial differences were not collected[1].
Safety Profile
The safety profile of Fluorodopa F 18 is notable for the absence of reported adverse reactions in the clinical trial.
- Adverse Reactions: No adverse reactions were reported in the clinical trial, which precluded the evaluation of subgroup differences in side effects[1][5].
- Radiation Exposure: The estimated effective dose of radiation from Fluorodopa F 18 PET is approximately 5.6 mSv, similar to other commonly used diagnostic radiopharmaceuticals[5].
