L-carnosine Prophylactic Effect on Oxaliplatin Induced Peripheral Neuropathy in GIT Cancer Patients


This study evaluates the prophylactic effect of exogenous L-CARNOSINE in Oxaliplatin induced peripheral neuropathy, Thus half of the patients will receive L-CARNOSINE with Oxaliplatin and the other half will not receive L-CARNOSINE with their chemotherapy (oxaliplatin),And then neuropathy together with some oxidative stress markers will be assessed at the end of treatment duration (three months) .

Detailed Description

Oxaliplatin causes peripheral neuropathy , L-CARNOSINE is supposed to prevent this side effect possibly by reducing oxidative stress and enhancing the growth of nerves.This study is intended to clarify the effect and mechanism of action of L-CARNOSINE in preventing Oxaliplatin induced peripheral neuropathy in cancer patients.

Blood samples will be collected from the patients before starting the chemotherapy and at the end of treatment duration (3 months) and then oxidative stress markers will be measured in these samples


    • L-CARNOSINE is a supplement given with chemotherapy to prevent peripheral neuropathy.

Arms, Groups and Cohorts

  • Experimental: Treatment group
    • this arm will receive L-CARNOSINE PO (each patient will receive 1 tablet daily and each tablet contains 500 mg thus a total of 500 mg per day) together with their chemotherapy wich is oxaliplatin.
  • No Intervention: Control group
    • This arm wont receive L-CARNOSINE, they will receive their chemotherapy (oxaliplatin) only.

Clinical Trial Outcome Measures

Primary Measures

  • Assessment of peripheral neuropathy using neuropathy grading score “CTCAE”, version 4.0) also oxidative stress markers will be measured by ELISA kits.
    • Time Frame: Three months
    • The following markers will be measured by ELISA kits : Nrf2 induced oxidative stress pathways (GSH) NF-KB anti-inflammatory pathway (TNF- alpha) pro-apoptic signals (caspase 3)

Secondary Measures

  • Assessment of tumor markers (CA,CEA) in blood.
    • Time Frame: Three months
    • Tumor Markers (CA,CEA) will be assessed at the end of treatment duration to make sure that L-CARNOSINE didn’t interfere with the patients’ response to chemotherapy.
