NCT05200442
Doctors leading this study hope to learn about the safety of combining the study drug VS-6766 with another drug called cetuximab in colorectal cancer. This study is for individuals who have advanced colorectal cancer and their cancer has progressed while getting previous treatment or individuals who cannot take/tolerate previous treatments. If you choose to participate, your time in this research will last up to 24 months.
NCT06349590
A single arm, prospective, single center Phase1/2 Dietary intervention trial for subjects diagnosed with colorectal cancer and scheduled for tumor resection more than 21 days from informed consent. Subjects will be provided 21 days of standardized High-fiber/low-fat meals and complete a food diary up until lunch on the day prior to surgery. Blood samples will be collected at baseline and on the day of surgery. Stool samples will be collected throughout the dietary intervention period at specific timepoints, on the day of surgery, and 30 days post-surgery. Tissue from the tumor resection will be isolated for organoid cultures. Subjects will be followed per standard of care for up to 5 years or disease recurrence, whichever comes first. Subject may be treated for their cancer prior to surgery and/or during the follow-up period.
NCT03955510
The purpose of this study is to study the impact of Western lifestyle, including moderate alcohol consumption and delayed eating patterns on studying individuals' susceptibility to colorectal cancer. This study aims to increase our ability to identify individuals at risk for colorectal cancer in the future. Each subject will experience four conditions (each for one week in duration with a week +/- 2 days wash-out in between): (1) "right-time eating" / no alcohol, (2) "right-time eating" / with alcohol, (3) "delayed-eating" / no alcohol, (4) "delayed-eating" / with alcohol. The order of experiments will be randomized \[concealed randomization\]. All subjects will undergo unprepped sigmoidoscopy after each week of intervention. In Aim 2, all subjects will have an option to undergo a 24h circadian assessment in the Biological Rhythms Research Lab after each week of intervention. The Investigator will assess (i) central circadian rhythms by collecting hourly salivary samples for melatonin assays and (ii) peripheral rhythm in the intestinal tract by buccal swabs once every 2h (12 time points) as well as by rectal sampling twice (every 12 hr). For Aim 3, sigmoidoscopy without sedation will be used to obtain colonic samples as the safe method compared to colonoscopy, which has some small but finite risks associated with the procedure (e.g, bleeding or perforation) as well as sedation.
