Clinical Benefit of 18F-FET in Glioma.

Sponsor: Primo Biotechnology Co., Ltd

Summary

This Phase II clinical trial, sponsored by \*\*Primo Biotechnology Co., Ltd.\*\*, evaluates the clinical benefit of \*\*$\^{18}$F-FET PET/CT\*\* in diagnosing glioma. The study aims to compare the diagnostic performance of $\^{18}$F-FET PET imaging against traditional brain MRI, using surgical histopathology as the gold standard for verification. \*\*Study Design and Participants\*\* This is a single-center, open-label, non-randomized trial conducted in Taiwan. The study will enroll a total of \*\*36 participants\*\*, consisting of 6 healthy volunteers (to assess biodistribution and dosimetry) and 30 patients with suspected primary gliomas scheduled for surgery. \*\*Methodology\*\* The test drug, $\^{18}$F-FET, is a radiopharmaceutical that targets large neutral amino acid transporters (LAT). It is administered via intravenous injection at a dosage of 3MBq/kgw. * \*\*Volunteers\*\* undergo PET/CT scans immediately and every 20 minutes for 90 minutes. * \*\*Patients\*\* receive a static PET scan 40-50 minutes post-injection. \*\*Endpoints and Safety\*\* * \*\*Primary Endpoint:\*\* Diagnostic sensitivity compared to MRI. * \*\*Secondary Endpoints:\*\* Specificity, PPV, NPV, tumor-to-background ratios (TBR), and safety (adverse events/vital signs). * \*\*Radiation Safety:\*\* The total estimated radiation exposure is \*\*7.63 mSv\*\*, which is well below the international safety threshold of 100 mSv. \*\*Conclusion\*\* The trial seeks to establish $\^{18}$F-FET PET/CT as a safe and effective diagnostic tool for the pre-surgical assessment of gliomas, potentially providing higher sensitivity and more accurate lesion detection than conventional MRI in Asian cancer patients.
