Key results for 18F‐rhPSMA‐7.3 PET were previously presented at ASCO GU in February 2022.1 The findings presented at AUA2022 included Correct Detection Rate (CDR) assessment (the percentage of all patients scanned with at least one true positive PET finding as compared to the Standard of Truth of histopathology or confirmatory conventional imaging), and its impact on patient upstaging. They were based on individual read results from three blinded, independent PET readers. In total, the Efficacy Analysis Population (EAP) of 366 men had a composite Standard of Truth. Among EAP patients, 68% (250/366) had negative baseline conventional imaging. Among the 250 patients with negative baseline conventional imaging, 18F‐rhPSMA‐7.3 showed a CDR of 45─47% (113 ‐ 117/250) across the three readers. Among patients who had undergone prostatectomy, 3.5‐8.0% (7‐16/201) of 18F‐rhPSMA‐7.3 positive scans showed lesions in the prostate bed region, with 18‐21% (36‐43/201) in pelvic lymph nodes and 21‐ 26% (43‐52/201) in other sites that led to upstaging. Among patients who had received radiotherapy, these values were 39‐41% (18‐19/46), 6.5% (3/46) and 20‐30% (9‐14/46), respectively. Very few patients had an alternative primary therapy and no definitive conclusions could be drawn for them. The Late‐breaking Abstract was discussed in an oral Plenary Session presentation at AUA2022 on May 13, 2022, “Impact of 18F‐rhPSMA‐7.3 PET on upstaging of patients with prostate cancer recurrence: results from the prospective, Phase 3, multicenter SPOTLIGHT study,” by Mark T. Fleming, MD, Virginia Oncology Associates, U.S. Oncology Research, Norfolk, Va., on behalf of the SPOTLIGHT Study Group. The Journal of Urology abstract is available here. About Radiohybrid Prostate‐Specific Membrane Antigen (rhPSMA) rhPSMA compounds consist of a radiohybrid (“rh”) Prostate‐Specific Membrane Antigen‐targeted receptor ligand which attaches to and is internalized by prostate cancer cells and they may be radiolabeled with 18F for PET imaging, or with isotopes such as 177Lu or 225Ac for therapeutic use – creating a true theranostic technology. They may play an important role in patient management in the future, and offer the potential for precision medicine for men with prostate cancer. Radiohybrid technology and rhPSMA originated from the Technical University of Munich, Germany. Blue Earth Diagnostics acquired exclusive, worldwide rights to rhPSMA diagnostic imaging technology from Scintomics GmbH in 2018, and therapeutic rights in 2020, and has sublicensed the therapeutic application to its sister company Blue Earth Therapeutics. Blue Earth Diagnostics has completed two Phase 3 clinical studies evaluating the safety and diagnostic performance of 18F‐rhPSMA‐7.3 PET imaging in prostate cancer: (“SPOTLIGHT,” NCT04186845), in men with recurrent disease and (“LIGHTHOUSE,” NCT04186819), in men with newly diagnosed prostate cancer. Currently, rhPSMA compounds are investigational and have not received regulatory approval.
