About this study
Official title: The Possible Protective Role of N-Acetylcysteine Against Oxaliplatin-Induced Peripheral Neuropathy in Patients With Colorectal Cancer
This study investigates the possible protective role of N-Acetylcysteine against oxaliplatin-induced peripheral neuropathy in patients with colorectal cancer. The trial aims to evaluate whether N-Acetylcysteine can reduce the incidence and severity of neuropathy during chemotherapy.
Read the detailed description
Oxaliplatin, a common chemotherapeutic agent for colorectal cancer, often induces peripheral neuropathy, which can significantly affect patients' quality of life and limit treatment effectiveness. The neuropathy is partly caused by nerve inflammation and oxidative stress.
N-Acetylcysteine (NAC), an antioxidant, has been suggested to protect neurons from oxidative damage and reduce inflammation.
This interventional, randomized, parallel-assignment study will enroll colorectal cancer patients receiving oxaliplatin-based chemotherapy. Participants will be assigned to either receive N-Acetylcysteine alongside chemotherapy or chemotherapy alone. Primary outcomes include the incidence and severity of peripheral neuropathy measured at predefined intervals during treatment.
Secondary outcomes include biochemical markers of nerve inflammation and oxidative stress, including:
- Neurotensin (marker of nerve inflammation)
- Interleukin-6 (marker of systemic inflammation)
- Total Antioxidant Capacity (marker of oxidative stress)
The study aims to provide evidence on whether N-Acetylcysteine can serve as a protective agent against chemotherapy-induced neuropathy, potentially improving treatment tolerance and patient outcomes.

| Study group | Role | What they receive |
|---|---|---|
| NAC Group | Experimental | Patients receive modified FOLFOX-6 chemotherapy plus oral N-acetyl cysteine 1200 mg administered 1 hour before oxaliplatin throughout chemotherapy cycles. Receives: Drug: N-Acetyl Cysteine; Drug: Modified FOLFOX-6 regimen |

What is being measured
The primary outcome is the main question the study is designed to answer.
NCI-CTCAE, Version 5, 2017
The CTCAE is an international classification system used to assess and describe adverse events resulting from medical treatments, especially in cancer therapy, chemotherapy, and radiation therapy.
It provides standard criteria to grade the severity of each adverse event on a scale from 1 to 5:
Grade 1 (Mild): Mild symptoms, no intervention needed.
Grade 2 (Moderate): Symptoms require minimal intervention or slightly affect daily activities.
Grade 3 (Severe): Symptoms significantly impact daily activities or require medical intervention.
Grade 4 (Life-threatening): Life-threatening symptoms requiring urgent intervention.
Grade 5 (Death): Death due to the adverse event.
Measured: Adverse events will be assessed using NCI-CTCAE v5.0 at baseline (Day 1, prior to Cycle 1) and after Cycle 2 (Day 15) and after Cycle 4 (Day 29). Each chemotherapy cycle lasts 14 days.
FACT/GOG-Ntx-12
The FACT/GOG-Ntx-12 is a patient-reported outcome measure designed to assess chemotherapy-induced neurotoxicity, particularly from drugs such as platinum agents or taxanes.
It consists of 12 items evaluating peripheral neuropathy symptoms, including numbness, tingling, pain, weakness in hands or feet, and difficulty with walking or handling objects.
Each item is scored on a 0-4 scale (0 = not at all, 4 = very much), providing a total score reflecting the severity of neurotoxicity.
It is primarily used to monitor the impact of chemotherapy on neurological function and related quality of life.
Measured: Neurotoxicity-related adverse events will be assessed using the FACT/GOG-Ntx-12 at baseline (Day 1, prior to Cycle 1) and after Cycle 2 (Day 15) and after Cycle 4 (Day 29). Each chemotherapy cycle lasts 14 days.
BPI-SF
The BPI-SF (Brief Pain Inventory - Short Form) is a patient-reported questionnaire used to assess pain severity and its impact on daily functioning.
It includes questions about the intensity of pain (e.g., worst, least, average, and current pain) and how pain interferes with activities such as walking, work, mood, sleep, and relationships.
Each item is rated on a 0-10 numeric scale (0 = no pain / no interference, 10 = worst imaginable pain / complete interference), allowing calculation of overall pain severity and interference scores.
It is widely used in cancer patients and other chronic pain conditions to monitor pain and response to treatment.
Measured: Pain severity and interference will be assessed using the BPI-SF at baseline (Day 1, prior to Cycle 1) and after Cycle 2 (Day 15) and after Cycle 4 (Day 29). Each chemotherapy cycle lasts 14 days.
Secondary outcomes (3)
Serum IL-6 as a marker of inflammation
Serum IL-6 is a pro-inflammatory cytokine commonly used as a biomarker of inflammation.
Elevated IL-6 levels indicate activation of inflammatory pathways, which can occur due to cancer, chemotherapy, or other physiological stressors.
Measurement of serum IL-6 allows monitoring of systemic inflammatory responses in patients undergoing chemotherapy.
Measured: IL-6 will be measured at pre-oxaliplatin infusion (baseline) and after infusion completion (post-dose) on Day 1 of Cycle 1 in both study arms. NAC is administered orally 1 hour before baseline sample in the intervention arm. Each FOLFOX cycle is 14 days.
Serum total anti-oxidant capacity (TAC) as a biomarker of oxidative stress
Serum total antioxidant capacity (TAC) is a biomarker of oxidative stress, reflecting the overall ability of the serum to neutralize free radicals and reactive oxygen species.
TAC is used to evaluate oxidative damage and antioxidant defense mechanisms, which can be affected by chemotherapy.
Measured: TAC will be measured at pre-oxaliplatin infusion (baseline) and after infusion completion (post-dose) on Day 1 of Cycle 1 in both study arms. NAC is administered orally 1 hour before baseline sample in the intervention arm. Each FOLFOX cycle is 14 days.
Serum neurotensin as a biomarker for neuropathy
Description:
Serum neurotensin (NT) is a peptide biomarker used to assess chemotherapy-induced neuropathy.
Changes in serum neurotensin levels correlate with peripheral nerve damage and neurotoxic effects caused by chemotherapeutic agents.
Measured: NT will be measured at pre-oxaliplatin infusion (baseline) and after infusion completion (post-dose) on Day 1 of Cycle 1 in both study arms. NAC is administered orally 1 hour before baseline sample in the intervention arm. Each FOLFOX cycle is 14 days.

What is this clinical trial studying?
A study testing N-Acetyl Cysteine and Modified FOLFOX-6 regimen in people with Colorectal Cancer, run by Tanta University at 1 site in Egypt.
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 8 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 10 Feb 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Egypt. 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.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
