Official title: The Possible Protective Role of Ketotifen Against Oxaliplatin Induced Peripheral Neuropathy in Patients With Colorectal Cancer

Status Recruiting

Clinical Trial Summary

The aim of current study is to evaluate the possible protective role of Ketotifen against oxaliplatin-induced peripheral sensory neuropathy in patient with stage III colorectal cancer.

This study will be a randomized placebo controlled parallel study.64 patients with colorectal cancer will be randomized to 2 groups:

Group I (control group; n=32) which will receive 12 cycles of modified FOLFOX-6 regimen plus placebo tablets twice daily.

Group II (ketotifen group; n=32) which will receive modified FOLFOX-6 regimen in addition to ketotifen 2 mg daily

Blood sample collection and biochemical assessment:

• Serum IL-6 as a marker of inflammation.

• Serum superoxide dismutase (SOD) as a biomarker of oxidative stress.

• Serum neurotensin as a biomarker for neuropathy.

Assessment of oxaliplatin induced peripheral sensory neuropathy will be done through:

• The implication of National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE, Version 5, 2017) for grading of neuropathy at baseline and by the end of every two oxaliplatin cycles.

• The use of Neurotoxicity- 12 item questionnaire score (Ntx-12) from the validated Functional Assessment of Cancer Therapy/Gynecologic Oncology Group "FACT/GOG-Ntx-12" at baseline and by the end of every two oxaliplatin cycles.

• The assessment of the severity of neuropathic pain through brief pain inventory short form "BPI-SF" worst item. Severity of neuropathic pain will be assessed at baseline and by the end of every two oxaliplatin cycles.

Clinical Trial Description

The aim of current study is to evaluate the possible protective role of Ketotifen against oxaliplatin-induced peripheral sensory neuropathy in patient with stage III colorectal cancer.

• Study design

This study will be a Randomized placebo controlled parallel study. Sixty four patients with stage III colorectal cancer will be scheduled to receive 12 cycles of modified FOLFOX-6 (folinic acid, flurouracil and oxaliplatin). Patients will be recruited from the Oncology Department, Tanta University Hospital, Tanta, Egypt. Staging will be done according to the American Joint Committee on Cancer 7th edition staging (Edge and Compton, 2010). At admission, patients will be randomized through sealed envelopes method with assignment codes (A and B) into two groups to receive either Placebo or ketotifen in addition to the chemotherapeutic regimen:

Group one (Placebo group or code A; n=32)

Patients will receive 12 cycles of modified FOLFOX-6 regiment plus placebo tablets daily throughout the twelve chemotherapy cycles. The chemotherapy cycles will be received every 2 weeks and will be as follows:

Day 1: Oxaliplatin 85 mg/m2 intravenous infusion in 250-500 mL 5% dextrose solution and leucovorin 400 mg/m2 intravenous infusion in 5% dextrose solution both were given over 120 minutes at the same time in separate bags using a Y-line access, followed by 5-fluorouracil 400 mg/m2 intravenous bolus given over 2-4 minutes, followed by 5-fluorouracil 2400 mg/m2 intravenous infusion in 500 mL 5% dextrose solution as a 46-hour infusion.

Group two (Ketotifen group or code B; n=32) Patients will receive the same chemotherapy regimen as group one in addition to oral ketotifen 2 mg daily throughout the twelve chemotherapy cycles.

Intravenous 5-HT3 antagonist plus pantoprazole will be administered to all participants before each cycle as prophylactic therapy against chemotherapy induced nausea, vomiting and mucositis.

Blood sample collection and biochemical assessment:

• Serum IL-6 as a marker of inflammation.

• Serum superoxide dismutase (SOD) as a biomarker of oxidative stress.

• Serum neurotensin as a biomarker for neuropathy.

Assessment of oxaliplatin induced peripheral sensory neuropathy will be done through:

• The implication of National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE, Version 5, 2017) for grading of neuropathy at baseline and by the end of every two oxaliplatin cycles.

• The use of Neurotoxicity- 12 item questionnaire score (Ntx-12) from the validated Functional Assessment of Cancer Therapy/Gynecologic Oncology Group "FACT/GOG-Ntx-12" at baseline and by the end of every two oxaliplatin cycles.

• The assessment of the severity of neuropathic pain through brief pain inventory short form "BPI-SF" worst item. Severity of neuropathic pain will be assessed at baseline and by the end of every two oxaliplatin cycles. ;
