Blue Earth Diagnostics Highlights Upcoming Presentation of Additional Results from Investigational Phase 3 LIGHTHOUSE Study of 18F-rhPSMA-7.3 in Newly Diagnosed Prostate Cancer

− Results to be presented at 2023 ASCO Genitourinary Cancers Symposium (ASCO GU) −

MONROE TOWNSHIP, N.J. & OXFORD, England, February 09, 2023--(BUSINESS WIRE)--Blue Earth Diagnostics, a Bracco company and recognized leader in the development and commercialization of innovative PET radiopharmaceuticals, today announced the presentation of additional results from its completed Phase 3 LIGHTHOUSE trial of 18F-rhPSMA-7.3 in newly diagnosed prostate cancer, at the upcoming ASCO GU 2023 Genitourinary Cancers Symposium (ASCO GU). The conference will be held in San Francisco, Calif., from February 16 to 18, 2023. 18F-rhPSMA-7.3 is an investigational Prostate-Specific Membrane Antigen-targeted radiohybrid (rh) PET imaging agent. The now completed LIGHTHOUSE Phase 3 clinical trial (NCT04186819) was a prospective, Phase 3, multi-center, single-arm, imaging study conducted in the United States and Europe to evaluate the safety and diagnostic performance of 18F-rhPSMA-7.3 Positron Emission Tomography (PET) in men with newly diagnosed prostate cancer. Currently, 18F-rhPSMA-7.3 is investigational and has not received regulatory approval.

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. The radiohybrid technology and rhPSMA originated from the Technical University of Munich, Germany. Blue Earth Diagnostics acquired exclusive, worldwide rights to rhPSMA imaging technology from Scintomics GmbH in 2018, followed by acquisition of exclusive rights to therapeutic applications in 2020. Blue Earth Diagnostics has 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. rhPSMA compounds are investigational and have not received regulatory approval.
