Clinical Trial Summary

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

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Investigating the possible efficacy of nitazoxanide through evaluation of its impact on overall response rate (ORR) and disease control rate (DCR).	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.	3 months
Primary	Evaluating the change in the serum level of Reduced glutathione (GSH)	Blood samples will be collected at baseline and 3 months after treatment.	3 months
Primary	Evaluating the change in the serum level of Superoxide dismutase (SOD)	Blood samples will be collected at baseline and 3 months after treatment.	3 months
Primary	Evaluating the change in the serum level of Nuclear factor-kappa B (NF-kB)	Blood samples will be collected at baseline and 3 months after treatment.	3 months
Primary	Evaluating the change in the serum level of Protein disulfide isomerase (PDI)	Blood samples will be collected at baseline and 3 months after treatment.	3 months
Secondary	Evaluating the one-year overall survival (1-year OS)	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.	12 months
Secondary	Evaluating the progression free survival (PFS)	PFS is defined as the time from randomization to investigator- assessed tumor progression. PFS will be determined as mean and median in months.	12 months
Secondary	Evaluating the safety and tolerability of nitazoxanide through investigating Liver function test (ALT (U/mL) and AST (U/mL)).	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.	3 months
Secondary	Evaluating the safety and tolerability of nitazoxanide through investigating Renal function test (SCr (mg/dL), BUN (mg/dL) and eCrCl (mL/min)).	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.	3 months
Secondary	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)).	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.	3 months
