His innovative work has the potential to enhance diagnostic capabilities in oncology.

Latest Patents

Drzezga holds a patent for "2-alkoxy-6-[18F]fluoronicotinoyl substituted lys-c(O)-glu derivatives as efficient probes for imaging of PSMA expressing tissues." This patent outlines the identification of 6-[F]fluoro-2-alkoxynicotinoyl substituted Lys-C(O)-Glu derivatives as effective imaging probes. These probes demonstrate superior performance compared to other known PSMA-specific ligands, such as [F]DCFPyL and [Ga]HBED-CC-PSMA. The 2-alkoxy derivative exhibits higher cellular uptake values than [F]DCFPyL, while the 4-alkoxy substituted derivative shows significantly lower uptake. In vivo PET studies have shown that the 2-alkoxy-substituted probes provide excellent visualization of PSMA positive ganglia, making them a valuable tool in clinical settings.

Career Highlights

Drzezga's career is marked by his dedication to advancing medical imaging technologies. His work has led to the development of probes that are not only effective but also easily accessible for clinical use. The 2-methoxy derivative he developed has shown exceptional clinical efficiency in detecting small prostate cancer lesions, including those that are undetectable with current gold standard methods. This innovation represents a significant advancement in the diagnosis of recurrent prostate cancer.

Collaborations

Drzezga has collaborated with esteemed colleagues, including Bernd Neumaier and Boris Zlatopolskiy. Their combined expertise has contributed to the successful development of innovative imaging probes that enhance diagnostic accuracy.
