Regulatory & Commercial Milestones
-
In 2020, the U.S. FDA approved Ga-68 PSMA-11 for PET imaging of recurrent prostate cancer, marking the first regulatory endorsement of its kind. Regulatory agencies in the EU and Australia have also granted approval or conditional status, catalyzing adoption[^3].
-
Ongoing trials aim to expand indications, including primary diagnosis, post-treatment surveillance, and theranostics, with preliminary promising data supporting broader use.
