Clinical Trial Summary

The objective of this pilot cohort study is to investigate associations between CIN and changes in gut microbiome composition profiles.

Description:

The long-term goal of this study is to alleviate the occurrence of CIN and to improve chemotherapy treatment outcomes. The identification of associations between CIN and chemotherapy-induced changes in gut microbiome composition profiles will increase our understanding of these mechanisms that underlie CIN. An increased understanding of the underlying mechanisms will provide targets for the development of novel interventions to help alleviate CIN.

Intervention

Other:

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in patient recruitment	Evaluate the feasibility of patient recruitment by using descriptive statistics to determine number of patients approached and number of patients enrolled.	Baseline, 14 days
Primary	Change in patient retention	Evaluate the feasibility of patient retention by using descriptive statistics to determine number of patients who completed the questionnaires at both assessments.	Baseline, 14 days
Primary	Change in patient specimen collection	Evaluate the feasibility of patient specimen collection by using descriptive statistics to determine number patients who provided stool samples at both assessments.	Baseline, 14 days
Primary	Change of the gut microbiome	Evaluate for changes in alpha and beta diversity as well as composition of the gut microbiome pre- and post-chemotherapy in patients who do and do not report chemotherapy-induced nausea (CIN) after chemotherapy. Region V3-V5 of the 16s rRNA gene will be targeted for sequencing and submitted to trimmomatic for reads trimming and quality control.	Up to 10 months
Primary	Associations between microbial composition functional profiles	Examine associations between microbial composition functional profiles pre- and post-chemotherapy in patients who report chemotherapy-induced nausea (CIN) after chemotherapy. Change in relative abundance of genus associated with CIN occurrence will be used to predict the function of the genus. We will use PiCrust to perform functional profiling.	Up to 10 months
Primary	Evaluate for differentially abundant metabolites	Evaluate for differentially abundant metabolites associated with microbiome diversity in patients who do and do not report chemotherapy-induced nausea (CIN) after chemotherapy. Metabolomics profiling of stool samples pre- and post-chemotherapy using liquid chromatography-tandem mass spectrometry (LC-MS/MS).	Up to 10 months
Primary	Evaluate for perturbed metabolic pathways	Evaluate for perturbed metabolic pathways associated with microbiome diversity in patients who do and do not report chemotherapy-induced nausea (CIN) after chemotherapy. Metabolomics profiling will be performed on stool samples pre- and post-chemotherapy using liquid chromatography-tandem mass spectrometry (LC-MS/MS), as well as RNA-Seq analyses.	Up to 10 months
