Pre-Transplant Nutrition Counseling in Patients With Multiple Myeloma (PREPARE)

5. november 2026 opdateret af: University of Utah

PREPARE: PRE-transPlant Nutrition Counseling to Attenuate Malnutrition and Improve REcovery in Patients With Multiple Myeloma

The primary endpoint of this pilot randomized controlled trial (RCT) will evaluate the feasibility and acceptability of an 8-week pre-hematopoietic stem cell transplant (HSCT) nutrition counseling intervention aimed at improving dietary intake and quality before HSCT to attenuate post-HSCT malnutrition among up to 20 patients with multiple myeloma (MM).

Hypothesis: An 8-week pre-transplant nutrition counseling intervention will be feasible and acceptable among patients with MM undergoing HSCT.

Detaljeret beskrivelse

Hematopoietic Stem Cell Transplantation (HSCT) is standard of care for multiple myeloma (MM), yet treatment-related toxicities result in post-transplant malnutrition in up to 80% of patients. Conditioning chemotherapy is associated with substantial toxicities, including severe nausea, vomiting, and mucositis, which impair oral intake and disrupt GI function. Peri-transplant malnutrition is associated with increased healthcare utilization, higher infection risk, greater incidence of mucositis, reduced quality of life (QOL), and worse survival.

This pilot, parallel-group randomized controlled trial evaluates the feasibility and acceptability of an 8-week nutrition counseling intervention designed to improve dietary intake and quality among 20 patients with MM undergoing HSCT (1:1 allocation). Counseling begins at the start of induction therapy and continues for 8 weeks through weekly 30-45 minute video sessions delivered by a registered dietitian. The intervention utilizes stepwise, incremental goals targeting energy intake, protein intake, and fruit/vegetable consumption, monitored via a dietary tracking application. Control participants receive usual standard of care, including written educational materials and one pre-HSCT dietitian consultation 2-3 weeks prior to HSCT to discuss anticipated side effects.

PRIMARY OBJECTIVES I. Conduct a pilot randomized controlled trial to evaluate the feasibility and acceptability of an 8-week pre-hematopoietic stem cell transplant (HSCT) nutrition counseling intervention aimed at improving dietary intake and quality before HSCT to attenuate post-HSCT malnutrition among up to 20 patients with multiple myeloma (MM).

EXPLORATORY OBJECTIVES I. Leverage the usual-care control arm to characterize longitudinal changes in protein and energy intake, diet quality, malnutrition risk and status, physical activity, and quality of life from baseline (post-diagnosis, pre-induction therapy) through approximately three weeks post-HSCT to inform refinement of intervention timing, duration, and outcome assessment.

II. Compare the sensitivity and specificity of recommended malnutrition screening tools relative to a validated malnutrition assessment tool to inform selection of the optimal screening tool for patients with multiple myeloma.

III. Estimate the effect of the intervention, compared with usual care, on post-HSCT malnutrition status to inform the design of a larger, adequately powered trial.

Intervention / Behandling
Eksperimentel: Nutrition Counseling Intervention

8-week pre-HSCT virtual nutrition counseling intervention (1 session per week, 30-45 minutes) delivered by a registered dietitian and completion of 1-3 weekly dietary tracking a dietary tracking application.

Participants receive one 30-45 minute virtual nutrition counseling session per week for 8 weeks starting on or within 7 days after Cycle 1 Day 1 of induction therapy. Sessions are delivered by a registered dietitian using the Nutrition Care Process framework with stepwise goal setting targeting energy, protein, and fruit/vegetable intake based on food records tracked via a dietary tracking application.

Standard clinical care including AICR educational booklet provided on Cycle 1 Day 1 of induction therapy and standard pre-HSCT dietitian consultation 2-3 weeks prior to transplant.

Participants receive standard medical care, including the American Institute for Cancer Research (AICR) Living with Cancer handbook on Cycle 1 Day 1 of induction therapy and a standard dietitian consultation 2-3 weeks prior to HSCT regarding expected treatment side effects.
