A Randomized Placebo Controlled Study of a Plant-Based Dietary Versus Supplement Versus Placebo Intervention in Patients With Monoclonal Gammopathy of Undetermined Significance (MGUS) and Smoldering Multiple Myeloma (SMM) - The Nutrition Prevention (NUTRIVENTION-3) Study
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The researchers are doing this study to look at how butyrate levels change in participants' stool after they are on a- plant-based diet for at least 12 weeks. All participants will have monoclonal gammopathy of undetermined significance (MGUS) or smoldering multiple myeloma (SMM). We will compare how the plant-based diet, omega-3 fatty acid and curcumin supplements, and placebo (an inactive substance that looks like the study supplements) affect butyrate levels in participants' stool.
