German Tech Holding examines investment in radiopharmaceutical startup

German Tech Holding GmbH & Co. 2026/09:35) — +++ Ad-hoc Announcement +++ German Tech Holding is examining an investment in a BioTech startup with a disruptive radiopharmaceutical for cancer diagnostics * Clinically proven zirconium-89-based method for PSMA-PET/CT imaging with several years of application and published clinical evidence * Up to 100-fold higher tumour-to-background contrast improves the early detection and localization of tumour foci and metastases * German Tech Holding is examining an investment of 10 % in Zirnostics GmbH Frankfurt/Main, 7 October 2026 — German Tech Holding GmbH & Co.

KGaA ("GTH"), a holding company founded in 2012 and based in Frankfurt am Main, is examining an investment opportunity in a startup with a radiopharmaceutical for cancer diagnostics that is already in clinical use. This is a zirconium-89-labelled tracer for PSMA-PET/CT imaging for the diagnosis of prostate cancer which, through delayed imaging, enables a significantly improved visualization and localization of tumour foci and metastases. The method has already been in clinical use for several years and is the subject of several published evaluations.

The Prostate-Specific Membrane Antigen (PSMA) is a target structure that is frequently strongly expressed in prostate cancer cells and their metastases. The zirconium-89-labelled radiopharmaceutical (tracer) makes these visible in PET imaging. Unlike conventional PET tracers, zirconium-89 permits image acquisition several days after injection. This results in an up to 100-fold higher tumour-to-background contrast and thus in significantly more precise detection, that is, visualization and localization of tumour foci and metastases.

As a result, even small or previously hard-to-detect tumour foci and metastases can be made visible and additional disease foci identified that are not discernible in conventional PSMA-PET/CT. GTH is currently examining financing options for an acquisition of the investment in Zirnostics GmbH.
