Clinical Trial Summary

This study will evaluate the feasibility of an 8-week vegan whole-food, plant-based dietary intervention in subjects with low risk CLL who are undergoing observation. Over the course of 8 weeks, participants will attend weekly group cooking classes via Zoom lead by a RD. Participants will also attend weekly individual meetings with a health coaches to assist with adherence to the dietary intervention.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Adherence to the Dietary Intervention	Adherence to the dietary intervention will be calculated using a dietary index developed specifically for this diet. Dietary adherence scores will be calculated using a pre- and post-intervention food frequency questionnaire, as well as 3-day food diaries obtained throughout the intervention.	Up to 24 weeks
Primary	Satisfaction with the Dietary Intervention	Subject satisfaction will be assessed post-intervention using an acceptability, appropriateness and feasibility questionnaire. The questionnaire does not use a scoring system, rather statements will be provided and participants will provide an answer ranging from "completely disagree" to "completely agree."	8 weeks
Primary	Cooking Class Adherence	Cooking class attendance will also be used as a measure of adherence.	8 weeks
Primary	Recruitment	Recruitment rate will be assessed by examining the number of potentially eligible participants, number contacted, consent rates, number completing the intervention.	Through study completion, an average of 1 year
Primary	Retention	Retention will be calculated using the number of participants who enroll in the study and the number of participants who complete the 8 week intervention.	8 weeks
Secondary	White blood cell count	Will be measured using standard methods.	Change from baseline at 4 weeks and 8 weeks.
Secondary	Absolute lymphocyte count	Will be measured using standard methods.	Change from baseline at 4 weeks and 8 weeks.
Secondary	Anthropometric Measures (height, weight, body mass index)	Will be measured using standard methods. Weight and height will be combined to report BMI in kg/m^2.	Change from baseline at 4 weeks and 8 weeks.
Secondary	Anthropometric Measures (waist circumference)	Will be measured using standard methods. Weight and height will be combined to report BMI in kg/m^2.	Change from baseline at 4 weeks and 8 weeks.
Secondary	Biomarkers of cardiometabolic health (complete metabolic panel)	Will be measured using standard methods.	Change from baseline at 4 weeks and 8 weeks.
Secondary	Biomarkers of cardiometabolic health (hemoglobin A1c)	Will be measured using standard methods.	Change from baseline at 4 weeks and 8 weeks.
Secondary	Biomarkers of cardiometabolic health (cholesterol and triglycerides)	Will be measured using standard methods.	Change from baseline at 4 weeks and 8 weeks.
Secondary	Concentration of vitamin B12	Will be measured using standard methods.	Change from baseline at 4 and 8 weeks.
Secondary	Concentration of vitamin B9	Will be measured using standard methods.	Change from baseline at 4 and 8 weeks.
Secondary	Concentration of iron	Will be measured using standard methods.	Change from baseline at 4 and 8 weeks.
Secondary	Concentration of ferritin	Will be measured using standard methods.	Change from baseline at 4 and 8 weeks.
Secondary	Blood pressure	Will be measured using standard methods, both systolic and diastolic blood pressure will be assessed.	Change from baseline at 4 weeks and 8 weeks.
