The goal of the analysis of the phase 3 SPOTLIGHT trial was to evaluate how clinical factors impact 18F-rhPSMA-7.3 detection rates in a population of patients with suspected recurrent prostate cancer, according to Benjamin H. Lowenritt, MD, FACS.
CancerNetwork® spoke with Benjamin H. Lowenritt, MD, FACS, a practicing urologist at Chesapeake Urology in Baltimore, Maryland, about the design of the phase 3 SPOTLIGHT study (NCT04186845) presented at the 2022 American Society for Radiation Oncology (ASTRO) Annual Meeting.Lowenritt indicated that the purpose was to determine the detection rate of 18F-rhPSMA-7.3 overall and in subgroups of patients with suspected recurrent prostate cancer.
The SPOTLIGHT trial is a study looking at 18F-rhPSMA-7.3, which is a novel PET PSMA agent used to help diagnose patients with prostate cancer. Specifically, the SPOTLIGHT study is looking at those patients who have biochemical recurrence after initial treatments for curative intent—either surgery or radiation—and the data is starting to emerge now that shows that it has good sensitivity and specificity. Specifically, this trial was looking at the overall detection rate, and then specifically the detection rates in certain subgroups.
