登记简述

BEAM-MM研究评估提高血液中β-羟基丁酸(BHB,一种人体在禁食或低碳饮食时自然产生的分子)水平是否安全、可行,并能否增强多发性骨髓瘤患者免疫治疗效果且保持良好耐受性。患者随机分配至四种干预组或对照组:生酮饮食(碳水化合物供能<10%),或口服δG®酮单酯((R)-3-羟基丁基(R)-3-羟基丁酸酯;CAS 1208313-97-6;TdeltaS Global, Inc.,英国牛津)每日3次,分低剂量(每次13.5 g,每日40.5 g)或高剂量(每次25 g,每日75 g),剂量遵循FDA GRAS批准范围;对照组接受标准营养护理。研究分为两部分:A部分纳入接受双特异性抗体治疗者,B部分纳入接受CAR-T治疗者,两部分均采用两种剂量水平。

This study investigates whether raising blood levels of beta-hydroxybutyrate (BHB) - a natural molecule produced by the body during fasting or a low-carbohydrate diet - is safe and feasible and can improve the effectiveness of immunotherapy in patients with multiple myeloma, while remaining safe and well-tolerated. Patients will be randomly assigned to one of four intervention groups or a control group. The intervention groups will either follow a ketogenic diet (less than 10% of calories from carbohydrates) or receive oral supplementation with deltaG® Ketone Monoester Performance \[(R)-3-hydroxybutyl (R)-3-hydroxybutyrate; CAS 1208313-97-6; TdeltaS Global, Inc., Oxford, UK\], administered orally three times daily at either a low dose (13.5 g per serving, 40.5 g/day) or a high dose (25 g per serving, 75 g/day), in accordance with the FDA GRAS-approved dosing range. The control group will receive standard nutritional care. The study includes two parts: Part A enrolls patients receiving bispecific antibody treatment, and Part B enrolls patients receiving CAR-T cell therapy. Both dosing levels are applied in each part.
