Curcumin in Preventing Gastric Cancer in Patients With Chronic Atrophic Gastritis or Gastric Intestinal Metaplasia
Study Details
Study Description
Brief Summary
This randomized phase IIb trial studies how well curcumin works in preventing gastric cancer in patients with chronic atrophic gastritis and/or gastric intestinal metaplasia. Curcumin is an antioxidant compound found in plants that may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Detailed Description
PRIMARY OBJECTIVES:
- To compare the change in gastric mucosal interleukin 1beta (IL-1beta) cytokine level, quantified by Luminex assay technology, after a 6-month intervention in participants randomly assigned to the curcumin (Meriva [curcuminoids]) versus placebo arms.
SECONDARY OBJECTIVES:
-
To determine the safety and tolerability of Meriva versus placebo. II. To compare changes in Histology Gastric Score (HGS) from baseline to 6 months for Meriva versus placebo.
-
To compare changes in additional gastric mucosal cytokine/chemokine levels (interleukin 8 [IL-8], tumor necrosis factor-alpha [TNFalpha], and inducible protein 10 [IP-10]; quantified by Luminex assay).
-
To compare changes in gastric mucosal deoxyribonucleic acid (DNA) damage as assessed by immunohistochemistry (IHC), of the biomarkers 8-hydroxy-2'-deoxyguanosine (8-OHdG) and phosphorylated subtype of histone H2A (H2AX).
-
To explore associations between proinflammatory cytokine genotype status (IL-1beta, IL-8, and TNFalpha single nucleotide polymorphisms [SNPs]; characterized at baseline) and the above outcomes.
OUTLINE: Patients are randomized into 1 of 2 arms.
ARM 1: Patients receive curcumin orally (PO) twice daily (BID) for 180 days in the absence of unacceptable toxicity.
ARM 2: Patients receive placebo PO BID for 180 days in the absence of unacceptable toxicity.
After completion of study treatment, patients are followed up at 30 days and 7 months.

Outcome Measures
Primary Outcome Measures
- Absolute change in IL-1beta cytokine levels in the gastric mucosa [Baseline up to 6 months]
Will be measured by Luminex assay. If the data are not normally distributed, the Wilcoxon Rank-Sum test will be used. The 95% confidence intervals will also be provided.
Secondary Outcome Measures
- Incidence of adverse events [From time of first dose of curcumin up to 7 months]
Will be graded by National Cancer Institute Common Terminology Criteria for Adverse Events version 4. The maximum grade for each type of adverse event will be recorded for each participant and frequency tables will be reviewed to determine the overall patterns. The number and severity of adverse events (overall and by intervention group) will be tabulated and summarized.
- Change in histology gastric score [Baseline up to 6 months]
Will compare changes in histology gastric score for curcumin versus placebo.
- Additional gastric mucosal cytokine/chemokine levels (IL-8, TNFalpha, and IP-10) [Baseline up to 6 months]
Will be quantified with Luminex assay. Changes in the concentrations (or categories) will be explored within and between the intervention arms. Fisher's exact tests, Wilcoxon rank sum tests, and two-sample t-tests will be used to assess differences between groups. McNemar's tests, Wilcoxon signed rank tests, and paired sample t-tests will be used to assess differences within each arm. Graphical methods (i.e. boxplots, scatter plots, etc.) will also be used to describe the data.
- Gastric mucosal deoxyribonucleic acid (DNA) damage [Baseline up to 6 months]
Will be assessed by immunohistochemistry. Fisher's exact tests, Wilcoxon rank sum tests, and two-sample t-tests will be used to assess differences between groups. McNemar's tests, Wilcoxon signed rank tests, and paired sample t-tests will be used to assess differences within each arm. Graphical methods (i.e. boxplots, scatter plots, etc.) will also be used to describe the data.
Other Outcome Measures
- Proinflammatory cytokine genotype status (IL-1beta, IL-8, and TNFalpha single nucleotide polymorphisms) [At baseline]
Will be examined in relation to the outcomes above to further characterize the at-risk population and generate hypotheses for future studies.

-
Not pregnant or breast feeding; Note: The effects of Meriva on the developing human fetus at the recommended therapeutic dose are unknown; for this reason, individuals of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation; should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her study physician immediately
Exclusion Criteria:
-
PRE-REGISTRATION EXCLUSION CRITERIA
