Active Comparator: Experimental arm with Intratympanic NAC injection
One ear will be randomly chosen for the experimental treatment and receive intratympanic NAC injections 60 minutes prior to their scheduled chemotherapy sessions
Drug: N-Acetyl Cysteine
One ear will be randomly chosen for the experimental treatment of intratympanic NAC. The other ear will serve as the control ear which will not receive any injection.
Other Name: NAC
No Intervention: Control arm with No injection
The control ear will not receive any injections
- Determination of a safe and tolerable dosage for intratympanic NAC injection [ Time Frame: Within 1 day ]The primary end-point of the phase 1 part of this study is the safety and tolerability of intratympanic NAC injections, by determining the causality of adverse events and serious adverse events and grading according to National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) v.5.0
- Improvement in hearing threshold with intratympanic NAC injection [ Time Frame: Within 2 months ]The primary outcome measure of this study will be a comparison of hearing loss between the control and NAC-injected ears. More specifically, each ear will be scored as having hearing loss if there is a greater than 10dB hearing loss in three contiguous frequencies. This will be measured via threshold hearing tests.
- Improvement in hearing quality with intratympanic NAC injection [ Time Frame: Within 2 months ]The secondary outcome measure of this study will be a comparison of hearing discrimination, subjective tinnitus, otoacoustic emission, speech spatial and quality of hearing between the control and NAC-injected ears.
