Transtympanic Sodium Thiosulfate to Prevent Cisplatin-related Hearing Loss A Randomized Controlled Multicenter Phase III Trial; The SOUND Trial
The goal of this clinical trial is to learn if transtympanic sodium thiosulfate (STS) injections can prevent hearing loss caused by cisplatin chemotherapy in adults with head and neck cancer. The main question it aims to answer is: Researchers will compare the ear treated with STS gel to the untreated ear within the same patient to see if STS prevents hearing loss. Participants will: 1. Receive STS gel injections into the middle ear of one ear (randomized) within 3 hours before each cisplatin infusion (3-7 injections per patient). 2. Undergo hearing tests at baseline and 2-4 months after the last cisplatin treatment. 3. Complete questionnaires about hearing and tinnitus at baseline and 2-4 months after treatment.
• Histological or cytological proof of solid head and neck malignancies with an indication for treatment with cisplatin in a cumulative dose of ≥ 200mg/m2 given in a weekly schedule of 7 times 40 mg/m2 or a 3-weekly schedule of 3 times 100 mg/m2
• Treatment with high-dose cisplatin (cumulative dose ≥ 200mg/m2) of maximum 7 cycles
• Able and willing to give written informed consent;
• WHO performance status of 0, 1 or 2;
• Age older than 18 years.
