Official title

The Role of the Microbiome in Colorectal Cancer Onset and Progression

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This is an observational study with the goal to improve the robustness of the scientific evidence linking Fusobacterium nucleatum (Fn) and/or other microorganisms to colorectal cancer (CRC) onset and/or progression. This is an approximately three-year study. There are two phases to this study, including: 1) pilot phase, 2) full study. There are also five arms in this study including cancer-free, pre-cancerous, and Colorectal cancer stages (I-III). The pilot study will include the recruitment of 50 participants per group (i.e., total of 250 participants). The full study will have an additional 150 participants per group (total of 1,000 participants). This study will recruit using clinical sites in the United States. There are 5 timepoints in this study. If the participants are found to be medically eligible through diagnosis and medical information, they will provide samples (including: saliva, blood, urine, stool and tumor biopsy) at each timepoint and during the study. They will also answer health and wellness questions during this study. Additional data collection, including medical data, biopsies and other biological samples might happen at interim timepoints in case of adenoma/cancer disease progression (recurrence, metastasis). The participant's healthcare provider will determine if additional biopsies are required as a part of the standard of care. If collected, additional samples will be sent for research purposes.
