Study to Evaluate Safety and Efficacy of DB-020 to Protect Hearing in Patients Receiving Cisplatin for Cancer Treatment

Completed · Phase 1 · Has a placebo group

Conditions studied: Ototoxicity

In brief

The purpose of this study is to evaluate whether DB-020 administered via an injection in the middle ear prevents hearing loss in participants who will receive high doses of cisplatin as part of their treatment for cancer.
