BF844 is a chemical compound that demonstrates the ability to mitigate hearing loss in individuals with Usher Syndrome Type III (USH3) caused by the CLRN1 mutation (specifically N48K). One of its mechanisms of action is the transportation of CLRN1 N48K to the plasma membrane. In vivo studies have shown that BF844 significantly preserves hearing [1].
Sodium thiosulfate (Pentahydrate) is an antioxidant and antifungal. Sodium thiosulfate protects against cisplatin-induced hearing loss in children and is not associated with serious adverse events attributed to its use[3]. The addition of sodium thiosulfate, administered 6 hours after cisplatin chemotherapy, resulted in a lower incidence of cisplatin-induced hearing loss among children with standard-risk hepatoblastoma, without jeopardizing overall or event-free survival[4]. Calciphylaxis is a potentially fatal disorder of abnormal calcium deposition. Treatment is multifaceted, and improved outcomes have been demonstrated with intravenous sodium thiosulfate; however, the use of this medication can be limited by its adverse effects[5]. TST (topical sodium thiosulfate) appears to be a relatively well-tolerated adjuvant treatment for CC(calcinosis cutis)[6]. The combined treatment of sodium thiosulfate, pamidronate and calcitomimetics has been effective and safe for the treatment of calciphylaxis, inducing complete remission[7].
