HAYWARD, Calif. & MELBOURNE, Australia--(BUSINESS WIRE)--RefleXion Medical, a therapeutic oncology company pioneering biology-guided radiotherapy* (BgRT) as a new modality for treating all stages of cancer, and Telix Pharmaceuticals Limited (ASX: TLX), a radiopharmaceutical company developing molecularly-targeted radiation (MTR) products, today announced a strategic collaboration to investigate the clinical utility of combining the companies’ technologies to improve treatment for high-risk or recurrent prostate and aggressive kidney cancers.
“Telix’s cancer-specific PET tracers may provide a more complete and robust signal to guide BgRT for difficult-to-treat cancers of the prostate and kidney”

Under the agreement, the parties will evaluate several new positron emission tomography (PET) tracers, including 68Ga-PSMA-11 for prostate cancer and 89Zr-Girentuximab for kidney cancer1, to evaluate their potential in guiding BgRT to treat disease.
“The Telix tracers show considerable potential for detecting metastatic disease,” said Phuoc Tran, M.D., Ph.D., professor of radiation oncology and molecular radiation sciences, oncology and urology at the Johns Hopkins School of Medicine. “Combining them with RefleXion’s BgRT, which is designed to treat metastatic disease, could bring us a step closer to improving outcomes for these cancer types.”
BgRT uses biological emissions from a patient’s cancer cells created by injecting a small amount of a targeting molecule carrying a positron-emitting radioisotope known as a PET tracer to guide external-beam radiotherapy (EBRT). As the PET tracer binds to the tumor cells, it produces emissions that signal the cancer’s location. The RefleXion™ X1 machine detects these emissions using PET detectors and responds in real-time to direct BgRT to each tumor and destroy it, even in moving tumors. The most commonly used PET tracer is 18F-fluorodeoxyglucose (FDG), which can detect many different cancer types. However, its performance in certain tumor types and organs remains limited, particularly for kidney and prostate cancers. Telix’s new PET tracers are designed to target specific cancer types and are expected to be more accurate in this clinical setting.
“Telix’s cancer-specific PET tracers may provide a more complete and robust signal to guide BgRT for difficult-to-treat cancers of the prostate and kidney,” said Thorsten Melcher, Ph.D., chief business officer at RefleXion. “This collaboration is an important step in providing proof-of-concept that PET-based tumor emissions can guide our BgRT using different tracers and in different cancer types.”
