Ototoxicity, Drug-Induced Clinical Trial
Official title:
Cisplatin and Sodium Thiosulfate Otoprotection With or Without SAHA/Vorinostat Histone Deacetylase Inhibition for Relapsed/Refractory Hepatoblastoma and Other Embryonal Tumors
This study will attempt to demonstrate the efficacy of Sodium Thiosulfate (STS) in preventing hearing loss in patients re-treated with cisplatin-based therapy according to regimens Cisplatin and STS (regimen CS) and Cisplatin, STS and Vorinostat/SAHA (regimen CSS).
This trial will assess the effect of STS in preventing subsequent hearing loss when patients are re-challenged with cisplatin therapy at relapse/progression, as well as the efficacy of cisplatin/STS or cisplatin/STS/SAHA for patients with relapsed hepatoblastoma, Wilms, Germ Cell Tumor (GCT) and Neuroblastoma stratified by initial cisplatin sensitivity. Important pharmacokinetic measurements focused on cisplatin and STS in children, with varying degrees of renal function, will be assessed. Such pharmacokinetic data will fill a current gap in our clinical knowledge base and enable safer use of such agents for all children with such cancers, regardless of kidney function, in the future. ;
