MagForce AG, a Berlin-based medical technology company founded in 1997 as a spin-off from Charité – Universitätsmedizin Berlin, develops and commercializes nanotechnology-based therapies for solid tumor treatment through magnetic hyperthermia; its core NanoTherm therapy system comprises NanoTherm, a superparamagnetic iron oxide nanoparticle ferrofluid injected intratumorally; NanoActivator, an applicator generating alternating magnetic fields to induce hyperthermic tumor ablation up to 70 degrees Celsius; and NanoPlan, therapy planning software simulating temperature distribution. The company targets glioblastoma and other solid tumors, with CE-marked approval since 2010 for brain tumor applications delivered at NanoTherm centers in German university hospitals including Charité Berlin, Münster, Kiel, Cologne, and Frankfurt, as well as a mobile unit in Poland; it operates primarily in Europe via subsidiaries like MagForce USA Inc. for US clinical advancement in prostate cancer focal ablation. Following financial challenges, MagForce filed for insolvency proceedings in July 2022 with official opening in October 2022, leading to near-total share value loss, delisting from the Frankfurt Stock Exchange, and suspension of operations, with its OTC ticker MGFRF reflecting negligible trading value into 2025 amid ongoing restructuring discussions.
