Study summary

Evaluation of the Effect of N-acetylcysteine in Preventing Cisplatin-Induced Toxicities in Cancer Patients

Read the detailed description

Cisplatin is a clinically advanced and highly effective anticancer drug used in the treatment of a wide variety of malignancies, Cisplatin was the first heavy metal compound to be used as an antineoplastic, and since its approval by the FDA in 1978, it is one of the most widely used agents in cancer therapy .

It has been used, sole or combined with other chemotherapeutic agents or even in combination with radiotherapy, in the treatment of several types of cancer, such as cancer of the testicles, ovarian, bladder, lung, head and neck, pancreas, breast, endometrium, esophagus, advanced cervical cancer, lymphomas, metastatic osteosarcomas and melanomas.

The therapeutic effect of cisplatin is significantly increased with dose-escalating, but high-dose therapy is limited by severe toxicities, with nephrotoxicity, neurotoxicity, and ototoxicity being the most important complications. In the case of nephrotoxicity, preventive measures such as saline hydration and osmotic diuresis are employed in clinical practice with minor success.

N-acetylcysteine (NAC) is a thiolic amino acid that has been reported to scavenge free radicals, replenish reduced glutathione (GSH), prevent its depletion, and inhibit lipid peroxidation (LPO). It can also restore the deterioration in the pro-oxidant/antioxidant balance via its metal-chelation activity.

Previous studies suggest that pre-administration of NAC attenuates carboplatin-induced injury in the cochlea of rats. As a GSH prodrug and antioxidant, NAC may ameliorate cochlear damage through a variety of mechanisms, such as providing a substrate for cochlear GSH synthesis, free radical scavenging, and inhibition of cell death pathway activation and necrosis.

To date, no clinical trial has been performed to evaluate the preventive potential of oral 1200 mg N-acetylcysteine on cisplatin-induced ototoxicity, hence this trial is designed to examine its effect on ototoxicity, nephrotoxicity, and neurotoxicity in cancer patients treated with cisplatin

Blood samples will be withdrawn from the study patients after enrollment to evaluate each of the following:

  1. Complete blood picture (CBC) every cycle
  2. Liver transaminases (AST and ALT) at baseline
  3. Serum creatinine and blood urea nitrogen every cycle

Baseline glomerular filtration rate will be calculated according to the Cockcroft-Gault formula:

creatinine clearance (ml/min) = (140-age) x body weight plasma creatinine(mg/dl) x 72 The obtained value was multiplied by 0.85 for women.

  • Baseline clinical investigations

    1. Audiometric test at baseline and every 2 cycles) patients will undergo conventional pure-tone audiometry in a soundproof room. The pure-tone thresholds for each ear will be measured at frequencies of 250, 500, 1000, 2000, 4000, and 8000 Hz).( bc cancer)
    2. Common terminology criteria for adverse event (CTCAE) version 4 (BC CANCER)
    3. The Functional Assessment of Cancer Therapy/Gynecologic Oncology Group-Neurotoxicity (FACT/GOG-Ntx) subscale.
  • Follow-up and end-of-study evaluation The follow up of the patient will occur at the end of each cycle (after 21 days) and at the end of the study after receiving his or her 4th cycle.

Inclusion criteria

  • Patients are eligible for inclusion if they meet the following criteria:

    • Cancer patients aged >18 years receiving cisplatin-containing chemotherapy.
    • A cisplatin dose starting from 75 mg/m2.
    • Various cancer types.
    • Both males and females.
    • No history of organ transplantation or kidney dialysis.
    • performance (ECOG):0-2

Exclusion criteria

Exclusion Criteria:

  • Patients with peripheral neuropathy.
  • Preexisting unilateral or bilateral moderate to severe sensorineural hearing loss
  • Patients with speech discrimination affection or those who are unable to participate in audiologic evaluation
  • Co-administration of ifosfamide with cisplatin, because of the known risk of nephrotoxicity.
  • Pregnancy or lactation.
  • Infection with the (HIV).
  • Prior administration of cisplatin.
  • Intraperitoneal chemotherapy.
  • Inadequate liver function ( > 1.5 times upper normal limit [] and [ALT] or aspartate transaminase [AST] > 3 times the upper normal limit [ULN] or up to 5.0 upper normal limit [ULN] in the presence of hepatic ).
  • Inadequate renal function (creatinine > 1.25 times upper normal limit [ULN], \< 50mL/min).
  • Serious comorbid systemic disorder incompatible with the study (uncontrolled diabetes mellitus or hypertension, myocardial infarction within the last 6 months).
  • Patients diagnosed with kidney cancer.
  • Exposure to any nephrotoxic drugs or agents.
Terms in these criteria, in plain language(7)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

ECOG performance status

A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

Creatinine clearance (CrCl)

How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 7, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
