About this study

Official title: Prevention of Cisplatin Ototoxicity With the Antioxidant Alpha-Lipoic Acid

RATIONALE: Alpha-lipoic acid may prevent or lessen hearing loss caused by cisplatin.

PURPOSE: This randomized clinical trial is studying the effectiveness of alpha-lipoic acid in preventing hearing loss in cancer patients undergoing treatment with cisplatin.

Read the detailed description

OBJECTIVES:

Primary

Determine the ability of alpha-lipoic acid supplementation to prevent or reduce the incidence and severity of hearing loss in cancer patients undergoing treatment with cisplatin.

Secondary

Determine if this drug improves the oxidative state, as measured by a malondialdehyde measurement of oxidative stress, thereby protecting the patient against ototoxic-induced hearing loss.

OUTLINE: This is a placebo-controlled, double-blind, randomized, multicenter study. Patients are stratified by cancer stage and institution. Patients are randomized to 1 of 2 treatment arms.

Arm I: Patients receive oral alpha-lipoic acid supplement once a day beginning 1 week before the start of cisplatin treatment and continuing for up to 1 month after the completion of cisplatin. During cisplatin treatment, patients discontinue supplement 1 day prior to the cisplatin treatment and resume daily supplements 2 days post treatment.

Arm II: Patients receive oral placebo supplement once a day beginning 1 week before the start of cisplatin and continuing for up to 1 month after the completion of cisplatin. During cisplatin treatment, patients discontinue supplement 1 day prior to the cisplatin treatment and resume daily supplements 2 days post treatment.

Hearing and ototoxicity are assessed at baseline, on each day of chemotherapy, and at 1 and 3 months post chemotherapy.

Blood samples are collected periodically to measure malondialdehyde and alpha-lipoic acid levels.

After completion of treatment with cisplatin, patients are followed for 3 months.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • alpha-lipoic acidDrug

    Also called lipoic acid

    Supplements (1200mg once a day) or placebo will be administered to each patient prior to first cisplatin treatment and continue until 3 months after last treatment.

  • AudiologyBehavioural

    Also called ototoxicity monitoring

    otoscopy, immittance screening, noise exposure questionnaire and individualized behavioral pure-tone in the convention and high-frequency ranges.

  • laboratory biomarker analysisBiological

    Also called MDA

    Plasma concentrations of Malondialdehyde (MDA) will be measures as an indicator of oxidative stress.

  • PlaceboDrug

    Placebo will be administered to each patient prior to first cisplatin treatment and continue until 3 months after last treatment.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Ototoxicity Measurement

    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.

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

Secondary outcomes (2)
  1. Malondialdehyde (MDA) Levels

    Computed maximum increase relative to baseline for each subject = (max MDA during treatment) - baseline MDA level.

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

  2. Total Amount of Prescribed Cisplatin Dose Administered

    Maximum cumulative dose of cisplatin (mg/m^2) administered during the course of chemotherapy.

    Measured: cisplatin treatment period between 10 weeks and up to 16 weeks.

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing alpha-lipoic acid, Audiology and laboratory biomarker analysis in people with Ototoxicity and Unspecified Adult Solid Tumor, run by US Department of Veterans Affairs at 2 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 7 Mar 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 29 Jan 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Ototoxicity Measurement (time frame: Baseline measurement occurred prior to first cisplatin treatment session. Follow-up measurements occurred up to 3 months after last cisplatin treatment.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Mar 2014.
