First Patients Dosed in Phase III ZIRCON Trial of Renal Cancer Imaging Product in Turkey

MELBOURNE, Australia and ISTANBUL, Turkey, Oct. 22, 2020 (GLOBE NEWSWIRE) -- Telix Pharmaceuticals Limited (ASX: TLX, ‘Telix’, the ‘Company’) and Eczacıbaşı-Monrol Nuclear Products Co. (‘Eczacıbaşı Monrol’) are pleased to announce that the first patients have been dosed in Telix’s Phase III ZIRCON clinical trial of Telix’s renal cancer diagnostic imaging product TLX250-CDx (⁸⁹Zr-girentuximab) in Turkey.

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. Under a contract manufacturing agreement, Eczacıbaşı Monrol will supply ⁸⁹Zr-labelled TLX250-CDx for the Turkish clinical sites.

The ZIRCON trial includes four participating clinical study sites in Turkey, comprising Istanbul Training and Research Hospital, Istanbul University-Cerrahpasa, Ankara Hacettepe University and Ankara University.¹

Telix Chief Medical Officer, Dr Colin Hayward stated, “We are pleased to have commenced the Phase III ZIRCON clinical trial in Turkey and wish to acknowledge the team at Eczacıbaşı Monrol, as well as the principal investigators and study teams at each of the four institutions participating in the study, who have made this important milestone possible.”

Aydın Küçük, General Manager of Eczacıbaşı Monrol added, “As one of our missions is to contribute to the human health, we are very honoured to be part of this significant achievement of the ZIRCON clinical trial initiation in Turkey with the first patients’ doses manufactured at our Istanbul facility, and we are thankful to the Telix team for this great collaboration.”

About the ZIRCON Study

ZIRCON (“Zirconium Imaging in Renal Cancer Oncology”) is an international multi-centre Phase III study at 33 sites in Europe, Australia, Turkey, Canada and the United States (subject to regulatory approval in the various jurisdictions). ZIRCON is a prospective imaging trial in approximately 250 renal cancer patients undergoing kidney surgery, to determine the sensitivity and specificity of TLX250-CDx PET imaging to detect clear cell renal cell cancer (ccRCC) in comparison with histologic “ground truth” determined from surgical resection specimens.

About TLX250 / TLX250-CDx
TLX250 (Girentuximab) is being developed by Telix Pharmaceuticals Limited both as a diagnostic PET imaging agent, ⁸⁹Zr-Girentuximab (Phase III) and a therapeutic radiopharmaceutical, ¹⁷⁷Lu-Girentuximab (Phase II). TLX250 is an antibody-based platform that targets carbonic anhydrase IX (CAIX), a cell surface target that is highly expressed in several human cancers including renal, lung and oesophageal cancer. High CAIX tumour expression is generally correlated with poor prognosis. Telix has prioritised the development of TLX250 for metastatic renal cell carcinoma (RCC), particularly the clear cell variant (ccRCC), which typically over-expresses CAIX.
