ARTMS Inc. and Telix Pharmaceuticals Limited announced they have successfully produced Telix’s prostate cancer imaging product, TLX591-CDx (Kit for the preparation of 68Ga-PSMA-11)1, using multi-Curie quantities of cyclotron-produced Gallium-68 (68Ga) via ARTMS’ proprietary Quantum Irradiation System (QIS®) solid target system. The testing demonstrated an impressive six-hour stability of TLX591-CDx, a radiopharmaceutical targeting Prostate-Specific Membrane Antigen (PSMA) for the imaging of prostate cancer using Positron Emission Tomography (PET). Testing exceeded all relevant quality control standards for both low- (50 mCi and 100 mCi) and mid-level output (over 2,500 mCi) 68Ga production runs. The “cold kit” format of TLX591-CDx enables rapid radiolabelling at room temperature with high radiochemical purity and production consistency, ideally suited for the radiopharmacy setting. ARTMS will continue the development of cyclotron-produced 68Ga with a focus on optimizing production potential and satisfying regulatory requirements for use in radiopharmaceutical kits such as TLX591-CDx.
