Hope for cancer patients: drug may shield ears from chemo damage
NCT ID NCT07364747
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether acetylcysteine, a drug often used for other purposes, can prevent hearing loss caused by cisplatin chemotherapy. About 40 adults receiving high-dose cisplatin will get either acetylcysteine or a placebo after each chemo session. Researchers will measure hearing changes over time to see if the drug offers protection.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- acetylcysteine (N-acetylcysteine)
- What this could lead to
- If it works, this could offer a simple way to prevent permanent hearing loss in patients receiving cisplatin chemotherapy.
- What could go wrong
- This is a small, early-phase trial with only 40 participants. The results may not apply to all patients, and acetylcysteine might not provide significant protection or could have side effects.

Inclusion Criteria: * Patients aged between 18 and 70 years * Patients scheduled to receive high-dose cisplatin-based chemotherapy regimens with a projected cumulative cisplatin dose of \> 200 mg/m2 and each dose \> 50 mg/m2 * Patients may receive concurrent chemotherapy with non-ototoxic agents * Patients may receive concurrent radiation therapy to the skull base, provided the radiation dose does not exceed the toxic threshold for ototoxicity * Patients receiving an appropriate antiemetic regimen consisting of Olanzapine or Neurokinin-1 (NK1) receptor antagonists * Patients receiving medical treatment at Siriraj Hospital. Exclusion Criteria: * Patients diagnosed with Nasopharyngeal Carcinoma (CA nasopharynx). * Patients with a history of head and neck radiation therapy where the radiation dose to the cochlea exceeded 9 Gy or the dose to the eustachian tube exceeded 50 Gy on both sides. * Patients who have received N-acetylcysteine (NAC) within 2 weeks prior to the start of the study. * Patients who have received other ototoxic drugs within 2 weeks prior to or during the study, including but not limited to: Aminoglycoside antibiotics, Vancomycin, Loop diuretics (e.g., Furosemide), High-dose Aspirin, Antimalarial drugs (e.g., Quinine) \- Patient with a known allergy or hypersensitivity to acetylcysteine.
