flag A new imaging agent detected metastatic triple negative breast cancer with high accuracy, outperforming standard PET scans, especially in the brain, and showing promise for future targeted treatments.

flag A Phase 2 trial called OPALESCENCE found that TLX250-CDx, a PET/CT imaging agent targeting carbonic anhydrase IX, effectively detected metastatic triple negative breast cancer with 87.5% overall sensitivity, including 100% sensitivity in breast, skin, and adrenal lesions, and outperformed standard FDG PET/CT in identifying brain metastases. flag It also showed high detection rates in lymph nodes and bone, with comparable tumor volume measurements and no safety concerns. flag The results support its potential for diagnosing aggressive, hypoxia-driven tumors and advancing future theranostic treatments using radioactive isotopes, though the agent remains investigational and unapproved.
