Telix's ZIRCON Phase III Kidney Cancer Imaging Study Presented in "Game Changing" Session at EAU

MELBOURNE, Australia, March 14, 2023 /PRNewswire/ -- Telix Pharmaceuticals Limited (ASX: TLX, Telix, the Company) today announces additional positive results from its completed pivotal Phase III ZIRCON study of TLX250-CDx (⁸⁹Zr-DFO-girentuximab) in clear cell renal cell carcinoma (ccRCC) (ClinicalTrials.gov Identifier: NCT03849118).¹

The results were featured in a "Game Changing" oral session delivered by Professor Dr. Peter Mulders from Radboud University Medical Centre (Netherlands), a ZIRCON Principal Investigator, at the 38^th Annual European Association of Urology (EAU) Congress, on Saturday, 11 March 2023.

Game Changing sessions are reserved for Phase III trials or other developments that the EAU's Scientific Congress Office believes will have a large impact on daily practice.

New data presented:

• TLX250-CDx demonstrated a high degree of consistency between readers with a very high sensitivity (85.5%) and specificity (87.0%) overall, and 85.5% / 89.5% for small masses (<4cm), confirming optimal SUVmax thresholds for image interpretation;
• The correlation of CAIX expression on histology with imaging results.

Professor Dr. Peter Mulders commented, "I'm delighted to be at EAU, the leading urological event in Europe, sharing further detailed results from Telix's Phase III ZIRCON study with the medical community. New data reinforces the clinical potential of this investigational agent, even in small renal masses which are most prevalent and present the highest diagnostic challenge, with remarkable consistency across readers. On behalf of Telix, I'd like to thank all the European sites and patients for their participation in this ground-breaking study."

Telix is in the process of establishing expanded access studies and supporting named patient programs for TLX250-CDx in the United States and Europe.
