Bladder cancer is the most common malignancy of the urinary tract. Approximately 75% of initially diagnosed bladder cancers are non-muscle invasive tumors, which means that the tumor is restricted to the mucosa. In 30-80% of the patients, recurrences occur, requiring repeated surgeries. About 45% of bladder cancers will progresses to a muscle-invasive bladder carcinoma.

Early detection, timely and appropriate treatment are therefore essential factors for improving the prognosis of urinary bladder carcinoma patients.

Photodynamic therapy (PDT) is a method of treating bladder tumors with a photosensitizer and light. The method is based on the selective accumulation of the photosensitizer in malignant cells and the irradiation of the tumor tissue with light of a specific wavelength. Subsequently, photochemical processes generate toxic substances that specifically damage the tumor.

Vidon® is developed by Sanochemia Pharmazeutika AG as a diagnostic and therapeutic option for patients with non-muscle invasive bladder cancer.
