Abstract: Disclosed is a method of impeding platinum-based chemotherapeutic induced ototoxicity, and/or other toxicity, the method comprising administering a colony stimulating factor 1 receptor (CSF1R) inhibitor to a subject in an amount sufficient to impede ototoxicity, and/or other toxicity, inducible by a platinum-based chemotherapeutic; and administering the platinum-based chemotherapeutic to the subject. The CSF1R inhibitor can be, for example, pexidartinib. The platinum-based chemotherapeutic can be, for example, cisplatin. Compositions, medicaments, kits, and uses are disclosed related to the same. Further, a method of screening for a compound able to impede a platinum-based chemotherapeutic induced toxicity is disclosed.

Abstract: The invention relates to a method for protecting sensory hair cells of the inner ear from damage caused by ototoxic drugs, in particular, aminoglycoside antibiotics, by administering to a vertebrate a growth factor, or mixture thereof. Additionally, the method protects against loss of sensory hair cells as a result of aging. In particular, the growth factor is an insulin-like growth factor or platelet-derived growth factor. The invention also relates to a method for detecting protection against an ototoxic drug on sensory hair cells of an inner ear of a vertebrate by a growth factor or biologically active fragment.
