Telix Pharmaceuticals Limited announced that the first patients have been dosed in the Phase III ZIRCON1 clinical trial of Telix’s renal cancer diagnostic imaging product TLX250-CDx (89Zr-girentuximab) in the United States. The objective of the ZIRCON trial is to evaluate the sensitivity and specificity of PET/CT imaging with TLX250-CDx to non-invasively detect clear cell renal cell carcinoma (ccRCC) in patients with indeterminate renal masses in comparison with surgical resection (histology), as the standard of truth. The ZIRCON trial, which includes twelve participating clinical study sites across the U.S. and Canada, initiated patient recruitment in U.S. on January 22, 2020 with the first patients being dosed with TLX250-CDx at University of California, Los Angeles (UCLA), and Seattle Cancer Care Alliance, University of Washington, Seattle (SCCA). The remaining seven U.S. sites2 and three sites3 in Canada are expected to commence patient recruitment progressively over the next month.
