Vidon® (PVP-Hypericin) is one of Sanochemia`s promising pipeline products and is being developed as a game changing technology in the management of bladder cancer. The patent covers the method for therapy of bladder cancer with Sanochemia’s developed PVP-Hypericin formulation. The U.S. patent will protect Vidon® until 2035.
“The Notice of Allowance for the US application of Vidon® for PDT is an important milestone to secure the long-term value of Vidon® for Sanochemia”, said Dr. Christina Abrahamsberg, CSO of Sanochemia Pharmazeutika AG.
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.
