BHB & CAR-T for Lymphomas

The aim of this study is to assess the feasibility of β-hydroxybutyrate (BHB) supplementation in individuals who are receiving therapy for lymphoma with standard-of-care anti-CD19 CAR T-cells (CAR-T) to determine whether BHB supplementation is safe and tolerable in this patient population. Additionally, this study will determine whether BHB supplementation leads to changes the gut microbiome and peripheral blood mononuclear cells (PBMCs). BHB supplementation will be performed through oral administration of HVMN Ketone-IQ, a commercially available BHB supplement, with an active ingredient of R- 1,3-Butanediol, which is converted to BHB.
