The Werkself players wore the new home shirt for the 2023/24 season with the cross on the chest for the first time in the match at the Spanish Champions League club. A badge marking the charity match on the front of the shirt was another highlight. The shirt auction raised €16,739. The top seller at the auction was the shirt worn by Florian Wirtz with a value of over €4,000.
The money raised will be used to carry out the first clinical study in Europe on the treatment of SPG50. Children from Spain and Germany will take part in this clinical study, which will build on a study previously carried out in the USA. Javier Garcia, president of the Columbus Foundation, said: "The Columbus Foundation thanks Bayer 04 for their great support. This enables us to start the second clinical study at the beginning of next year. The families of the children affected have great hopes in the study for the treatment of this previously incurable disease."
