bioXXmed AG (formerly CytoTools AG), a Germany-based holding company listed on the Basic Board of the Frankfurt Stock Exchange, invests equity in innovative biotechnology and medical technology companies focused on biomedicine, particularly dermatology and wound care; it provides financing through equity contributions, either alone or in consortium, while managing holdings as non-consolidated financial investments without conducting its own research and development. Founded in 2000 and headquartered in Darmstadt, Germany, the company holds a 68% stake in DermaTools Biotech GmbH, which develops products such as DermaPro, a dichloric acid-based solution for treating chronic wounds including diabetic foot ulcers and venous leg ulcers, and is the largest shareholder in CytoPharma GmbH, which advances therapies for cardiovascular diseases, cancer, urinary tract infections via Utisept bladder flushing device, and other indications encompassing small molecules and biologics targeting cell growth and programmed cell death mechanisms; geographic operations span Europe with regulatory pursuits in the European Union and United States, alongside prior licensing in India through partners like Centaur Pharmaceuticals. In September 2022, the company rebranded from CytoTools AG to bioXXmed AG to reflect its investment-holding focus; it acquired assets and contracts from the bankrupt DermaTools Biotech to sustain projects, notably advancing DermaPro toward medical device approval in Europe and the US; recent financials for the half-year ended June 30, 2025, report minimal sales of EUR 0.017 million and a net loss of EUR 0.256 million, amid intentions to raise capital for portfolio expansion in dermatology and wound care innovations.
