Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: FEED-FF
Participants will be asked to pick up the fermented foods at the Research Kitchen at Moffitt. Participants will be asked to eat 3-6 servings of FFs per day, from 1 week prior to treatment start through 12 weeks after treatment start/until the restaging scope is completed. At baseline, the end of week 6.5 and again at week 12.5, participants will be asked to provide biospecimens including a stool sample collected at home and a blood specimen collected in clinic. Participants will be asked to complete a food frequency questionnaire, a quality-of-life survey, two symptom related surveys, and a stool collection questionnaire at these same timepoints. After the dietary intervention, participants will be asked to complete an exit survey to provide feedback on the study and intervention. |
3-6 servings of any combination of the following fermented foods/day (from 1 week prior to treatment to approximately 12 weeks after the start of treatment): Yogurt, cottage cheese, kefir, kombucha, sauerkraut, and kimchi.
|
Active Comparator: Standard of Care (SUC)
Participants will receive general healthy eating handouts similar to current usual care documents provided in clinic. These handouts will detail typical healthy foods and the suggested level of intake, or servings per day. At baseline, the end of week 6.5 and again at week 12.5, participants will be asked to provide biospecimens including a stool sample collected at home and a blood specimen collected in clinic. Participants will be asked to complete a food frequency questionnaire, a quality-of-life survey, two symptom related surveys, and a stool collection questionnaire at these same timepoints. |
Standard of Care (SUC) is the treatment that is accepted by medical experts as a proper treatment for a certain type of disease and that is widely used by health care professionals.
Standard of Care will comprise general healthy eating handouts that describe typical healthy foods and the suggested level of servings per day.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Effects of the FEED-FF diet on clinical response to chemoradiation
Time Frame: At Baseline and Up to 12.5 Weeks
|
Clinical response measured in clinic by MRI/Endoscopy/Digital rectal exam, comparing the FEED-FF arm to SUC arm. Indicators of clinical response are Complete Response, Near Complete Response, Incomplete Response, or Progressive Disease. |
At Baseline and Up to 12.5 Weeks
|
Effects of FEED-FF diet on the gut microbiome
Time Frame: At Baseline, Week 6.5 and Up to 12.5 Weeks
|
Measured by fecal biospecimen sample collection; FEED-FF arm hypothesized to demonstrate increases in short chain fatty acid (SCFA) producing bacteria and higher alpha diversity compared to SUC arm.
|
At Baseline, Week 6.5 and Up to 12.5 Weeks
|
Effects of FEED-FF diet on local immune-related biomarkers
Time Frame: At Baseline and Up to 12.5 Weeks
|
Measured by FFPE tissue slides; FEED-FF arm hypothesized to demonstrate enhanced immune response such as higher T-cell expression compared to SUC arm.
|
At Baseline and Up to 12.5 Weeks
|
Effects of FEED-FF diet on quality of life
Time Frame: At Baseline, Week 6.5 and Up to 12.5 Weeks
|
Measured by using the European Organization for the Research and Treatment of Cancer (EORTC) Quality of Life (QoL) Survey; FEED-FF arm hypothesized to demonstrate more favorable QoL compared to SUC arm.
|
At Baseline, Week 6.5 and Up to 12.5 Weeks
|
Efficacy of the FEED-FF intervention
Time Frame: At Baseline, Week 6.5 and Up to 12.5 Weeks
|
Measured by an accrual rate of 50% of eligible patients, fermented foods (FF) intake of at least 3 servings on at least 80% of days, and at least 80% of intervention group reporting high/very high satisfaction with intervention. Weekly goal adherence via randomly administered food logs, tracking responses to and general completion of an exit survey will be utilized. |
