Trial Outcomes & Findings for Alpha-Lipoic Acid in Preventing Hearing Loss in Cancer Patients Undergoing Treatment With Cisplatin (NCT NCT00477607)

NCT ID: NCT00477607

Last Updated: 2014-03-07

Results Overview

Any American Speech and Hearing Association (ASHA)-significant hearing loss in the Sensitive Region for Ototoxicity frequencies between baseline measurement and any follow-up measurement. ASHA criteria are defined as * 20 decibel (dB) increase at any test frequency, * 10 dB increase at any two consecutive test frequencies, or loss of response where there was previously a response at any three test frequencies.

PRIMARY outcome

Timeframe: Baseline measurement occurred prior to first cisplatin treatment session. Follow-up measurements occurred up to 3 months after last cisplatin treatment.

Population: Intent-to-treat (ITT)

Any American Speech and Hearing Association (ASHA)-significant hearing loss in the Sensitive Region for Ototoxicity frequencies between baseline measurement and any follow-up measurement. ASHA criteria are defined as * 20 decibel (dB) increase at any test frequency, * 10 dB increase at any two consecutive test frequencies, or loss of response where there was previously a response at any three test frequencies.
