Prevention of Ototoxicity in NTM Patients Treated With IV Amikacin
Study Details
Study Description
Brief Summary
The goal of this clinical trial is to test the effectiveness of the study drug, ORC-13361, in preventing hearing loss in patients with NTM infection who are undergoing treatment with IV amikacin therapy. The main question this study aims to answer is:
-
Is ORC-13661 effective for preventing or lessening hearing loss induced by amikacin treatment?
-
Is ORC-13661 effective for preventing or lessening other measures of hearing impairment?
Participants will be asked to take a study drug while they are being treated with IV amikacin. Participants will take study drug for 90 days or until the end of their amikacin treatment, whichever comes first. During this time, researchers will gather clinical data on the participants' health.
Researchers will compare three groups - two groups taking different doses of the study drug and one group taking a placebo drug - to see if dose of drug has any effect on preventing hearing loss. A placebo is a look-alike substance that contains no active drug.

Detailed Description
Nontuberculous mycobacteria (NTM) are environmental bacteria that can cause chronic, debilitating pulmonary disease, primarily affecting those over age 60. In more severe cases of NTM infection, patients are given a therapy with parenteral aminoglycoside antibiotics (AGs), to achieve control or cure. Amikacin is the most commonly used aminoglycoside for treatment in this setting, however it is limited by in its use by its tendency to cause ototoxicity including hearing loss and/or vestibular dysfunction. Ototoxicity refers to substances (i.e. medications) which are damaging to the inner ear sensory cells and may result in functional hearing loss and other negative effects.
This main goal of this study is to test the effectiveness of the study drug, ORC-13661, a small molecule compound being developed as an adjunct therapy to be administered during AG use in order to prevent associated ototoxicity. This study is a randomized, double-blind, placebo-controlled, multicenter, dose-ranging clinical trial to compare the effects and safety of ORC-13661 in preventing or mitigating hearing in patients taking amikacin.
105 participants will be enrolled across 5 enrolling sites over the course of the study.
Participants will be randomized in equal numbers between three different study arms:
high-dose ORC-13661, low-dose ORC-13661, and placebo. Participants will take study drug for 90 days from the start of their amikacin treatment or until their amikacin treatment ends, whichever comes first.
The primary outcome of this study is prevention or mitigation of amikacin-induced ototoxicity. Secondary outcomes include changes in speech perception, auditory and balance effects, and quality of hearing.

Treatment regimen will run concurrently with treatment with IV amikacin. Study drug treatment will continue until treatment with IV amikacin ends or 90 days, whichever is earlier. |
Drug: ORC-13661

|
| Placebo Comparator: Placebo This arm is a daily treatment regimen of a placebo with a loading dose and a daily dose of placebo capsules to match the treatment arms. Placebo regimen will run concurrently with treatment with IV amikacin. Placebo regimen will continue until treatment with IV amikacin ends or 90 days, whichever is earlier. |

Outcome Measures
Primary Outcome Measures
- Mitigation or Prevention of Ototoxicity [Baseline to 28 (±5) days after study treatment discontinuation or 28 days after 90 days of study treatment, whichever comes first.]
Outcome is measured by changes from baseline using the American Speech-Language-Hearing Association (ASHA) shift criterion in patients with NTM disease undergoing treatment with IV amikacin therapy
Secondary Outcome Measures
- Mitigation or Prevention of hearing impairment with regards to speech perceptions [Baseline to 28 (±5) days after study treatment discontinuation or 28 days after 90 days of study treatment, whichever comes first.]
Outcome is measured by changes to patient's speech perceptions using the High Frequency Digits-in-Noise (HF-DIN) test
- Mitigation or Prevention of hearing impairment with regards to perceived auditory and balance effects [Baseline to 28 (±5) days after study treatment discontinuation or 28 days after 90 days of study treatment, whichever comes first.]
Outcome is measured by changes to patient's tinnitus using the Modified-Tinnitus Ototoxicity Monitoring Interview (TOMI)
- Mitigation or Prevention of hearing impairment with regards to speech, spatial and quality of hearing [Baseline to 28 (±5) days after study treatment discontinuation or 28 days after 90 days of study treatment, whichever comes first.]
Outcome is measured by changes to patient's Speech, Spatial and Quality of Hearing Scale (SSQ12)
