Ph. I/II Sodium Thiosulfate for OtoProtection During Cisplatin (STOP-CIS) (NCT07407582)

Phase I/II Open Label Trial of Intravenous Sodium Thiosulfate (Pedmarkยฎ) as Otoprotectant in Adults Receiving Cisplatin Chemotherapy (STOP-CIS)

๐ŸŸข Recruiting Phase1 / Phase2 ๐Ÿ’Š Investigational Drug / Biologic Sponsor: University of Arizona

๐Ÿฉบ Plain-English Summary (8th-Grade Level)

The purpose of this study is to assess the safety and effectiveness of a drug called Pedmarkยฎ sodium thiosulfate (STS) in reducing hearing impairment with standard of care cisplatin therapy. The safety and effectiveness of STS in reducing hearing loss has been well established in children and is approved for use in the pediatric and young adult population. However, information in adult patients is limited. As most cisplatin is administered in the adult population, this investigation would be of benefit.
