Nitazoxanide in Patients With Metastatic Colorectal Cancer

Registration Number
NCT06049901
Lead Sponsor
Tanta University
Brief Summary

The aim of this study is to evaluate the potential efficacy and safety of nitazoxanide in patients with metastatic colorectal cancer.

Detailed Description

Globally, colorectal cancer (CRC) is a major malignant tumor of the gastrointestinal tract which originates from epithelial cells of the colon and rectum. The efficacy of current cancer therapies is still limited by severe adverse effects on normal tissues and chemoresistance development. Therefore, recent efforts have been focused on the repurposing of existing drugs with good safety profiles for cancer treatment.

Nitazoxanide (NTZ) is considered a broad-spectrum anti-microbial drug with a potent activity against various helminths, anaerobic bacteria and viruses. NTZ inhibited the proliferation of CRC cell lines at or below concentrations that normally exhibit anti-parasitic activity.

Arm && Interventions
GroupInterventionDescription
Nitazoxanide GroupNitazoxanideThis group will include 30 patients who will be scheduled to receive 6 cycles of 5-Fluorouracil and Oxaliplatin- based regimens every 2 weeks plus nitazoxanide (500 mg orally twice daily) for 3 months.
Primary Outcome Measures
NameTimeMethod
Evaluating the change in the serum level of Superoxide dismutase (SOD)3 months

Blood samples will be collected at baseline and 3 months after treatment.

Investigating the possible efficacy of nitazoxanide through evaluation of its impact on overall response rate (ORR) and disease control rate (DCR).3 months

Abdominal, pelvic and chest CT scanning will be performed at baseline and after 3 months. ORR and DCR will be evaluated and categorized according to the RECIST 1.1 criteria. ORR includes patients with both complete response and partial response. DCR includes patients with complete response, partial response and stable disease. Both ORR and DCR will be determined as number and percentage.

Evaluating the change in the serum level of Reduced glutathione (GSH)3 months

Blood samples will be collected at baseline and 3 months after treatment.

Evaluating the change in the serum level of Protein disulfide isomerase (PDI)3 months

Blood samples will be collected at baseline and 3 months after treatment.

Evaluating the change in the serum level of Nuclear factor-kappa B (NF-kB)3 months

Blood samples will be collected at baseline and 3 months after treatment.

Secondary Outcome Measures
NameTimeMethod
Evaluating the safety and tolerability of nitazoxanide through investigating Renal function test (SCr (mg/dL), BUN (mg/dL) and eCrCl (mL/min)).3 months

These parameters will be followed up at baseline and 3 months after treatment. The reported adverse effects will be graded according to the National Cancer Institute- Common Terminology Criteria for Adverse Effects ( NCI-CTCAE) version 5.

Evaluating the safety and tolerability of nitazoxanide through investigating Liver function test (ALT (U/mL) and AST (U/mL)).3 months

These parameters will be followed up at baseline and 3 months after treatment. The reported adverse effects will be graded according to the National Cancer Institute- Common Terminology Criteria for Adverse Effects ( NCI-CTCAE) version 5.

Evaluating the one-year overall survival (1-year OS)12 months

OS is defined as the time from randomization to death from any cause is OS. One-year OS will be determined as mean and median in months.

Evaluating the progression free survival (PFS)12 months

PFS is defined as the time from randomization to investigator- assessed tumor progression. PFS will be determined as mean and median in months.

Evaluating the safety and tolerability of nitazoxanide through investigating Hematological parameters (hemoglobin (mg/dL), erythrocytes (cells/μL), leukocytes (cells/μL), platelets (cells/μL) and ANC (cells/μL)).3 months

These parameters will be followed up at baseline and 3 months after treatment. The reported adverse effects will be graded according to the National Cancer Institute- Common Terminology Criteria for Adverse Effects ( NCI-CTCAE) version 5.
