Enteral Nutrition Versus Standard of Care in Allogeneic Hematopoietic Stem Cell Transplantation

A Phase II Randomized Trial of Enteral Nutrition Versus Standard of Care in Allogeneic Hematopoietic Stem Cell Transplantation

This is a randomized controlled phase II trial which will enroll 112 patients with a diagnosis of a blood cancer or a serious blood disorder who plan to undergo an allogenic hematopoietic stem cell transplant using any conditioning regimen or graft source. Eligible patients will be randomized to receive standard of care (e.g., initiation of supplemental nutrition when oral intake declines) versus enteral nutrition via enteral feeding tube starting on day +1 post-transplant for at least 7 days, usually until engraftment.

Study Overview

• Status: Recruiting
• Conditions: Allogeneic Hematopoietic Stem Cell Transplant (Allo-HSCT)
• Intervention / Treatment: Dietary supplement: Enteral Nutrition

Detailed Description

This is a randomized controlled phase II trial which will enroll 112 patients with a diagnosis of a blood cancer or a serious blood disorder who plan to undergo an allogenic hematopoietic stem cell transplant using any conditioning regimen or graft source. Eligible patients will be randomized to receive standard of care (e.g., initiation of supplemental nutrition when oral intake declines) versus enteral nutrition via enteral feeding tube starting on day +1 post-transplant for at least 7 days, usually until engraftment. The primary endpoint will be cumulative incidence of stage 3-4 acute GVHD of the lower gut by day +100 post-transplant, whereas secondary endpoints will be stage 2-4 acute GVHD of the lower gut by day +100, grade 2-4 acute GVHD, weight loss and changes in lean muscle mass, changes in physical function, health-related quality of life, length of transplant hospital stay, and time to platelet and neutrophil engraftment. Assessments will include acute GVHD assessments and grading, Activities of Daily Living (ADL), Instrumental Activities of Daily Living (IADL), Fried Frailty Index, and Functional Assessment of Cancer Therapy-Bone Marrow Transplant (FACT-BMT).

Participation Criteria

Eligibility Criteria

• Ages Eligible for Study: Adult; Older Adult
• Accepts Healthy Volunteers: No

Description

Inclusion Criteria:

• Diagnosis of a hematological condition or serious blood disorder
• Patient planned for an allogeneic hematopoietic stem cell transplant
• Any conditioning regimen or graft source

Exclusion Criteria:

• Uncorrected anatomical deformity of the nose, nasopharynx, esophagus, or stomach that could prevent proper placement of a nasogastric tube.
• Chronic gastrointestinal conditions causing malabsorption or need for nutritional supplementation, e.g., celiac disease, short gut syndrome, chronic use of total parental nutrition or enteral nutrition for 3 or more months. Uncorrected anatomical deformity may include any known significant deviated nasal septum, large nasal polyps or other masses, or nasal or oropharyngeal trauma.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: The control (initiation of supplemental enteral or parenteral nutrition as clinically indicated); Subjects randomized to the control group with preserved oral intake will initiate conventional oral nutrition as tolerated. The dietary regimen is composed of a balanced general diet. Early supplemental nutrition will not be initiated in patients with the control group who are maintaining adequate oral intake.	Dietary supplement: Enteral Nutrition; A commercially available blenderized tube feed nutrition (BTF) formula will be initiated at a fixed starting rate of 25 ml/hr. The infusion rate will be increased in consultation with a registered dietitian nutritionist (RDN) based on tolerance to reach a feeding goal of 30-35 kcal/kg/day, which includes 1.5-2 g of protein/kg/day.
Experimental: The study group (enteral nutrition starting on day +1); The study group will start blenderized nutrition formula supplementation via enteral feeding tube on day +1 after transplant.	Dietary supplement: Enteral Nutrition; A commercially available blenderized tube feed nutrition (BTF) formula will be initiated at a fixed starting rate of 25 ml/hr. The infusion rate will be increased in consultation with a registered dietitian nutritionist (RDN) based on tolerance to reach a feeding goal of 30-35 kcal/kg/day, which includes 1.5-2 g of protein/kg/day.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Incidence of Stage 3-4 Acute GVHD of Lower Gut	Cumulative incidence will be calculated as the time to stage 3-4 acute GVHD of the lower gut for each of the study arms.	100 Days post- transplant

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Incidence of Stage 2-4 Acute GVHD of Lower Gut	Cumulative incidence will be calculated as the time to stage 2-4 acute GVHD of the lower gut for each of the study arms	100 Days post- transplant
Percent change in weight	Percent change from baseline weight at day +30 and day +100 post-transplant.	Day +30 and Day +100 post-transplant
Percent change in lean body mass	Percent change in total lean body mass measured by DEXA scan at baseline and day +30 post-transplant.	Baseline and Day +30 post-transplant
Platelet and neutrophil engraftment	Cumulative incidence curves of platelet engraftment and neutrophil engraftment will be generated using the methods of Gray to adjust for the competing risk of death to determine the probabilities of neutrophil and platelet engraftment.	Aproximately14 days post-transplant
Health-Related Quality of Life (HRQoL)	Functional Assessment of Cancer Therapy - Bone Marrow Transplant (FACT-BMT), total score range 0-148, where higher scores indicate better quality of life.	Baseline and Day +100 post-transplant
Transplant hospital stay	Median duration of transplant hospital stay compared between groups.	Up to approximately 30 Days Post Transplant
Fried Frailty Index score	Fried Frailty Index score ranges from 0 to 5, where higher scores indicate greater frailty (worse functional status).	Day +30, and Day +100 post-transplant
Activities of Daily Living (ADL)	Change in Activities of Daily Living (ADL) score from baseline to Day +30 and Day+100 post-transplant. The ADL scale ranges from 0 to 6, where higher scores indicate greater independence (better functional status).	Day +30, and Day +100 post-transplant
Instrumental Activities of Daily Living (IADL)	Change in Instrumental Activities of Daily Living (IADL) score from baseline to Day +30 and Day +100 post - transplant. The IADL score ranges from 0 to 8, where higher scores indicate greater independence (better functional status).	Day +30, and Day +100 post-transplant
Karnofsky Performance Scale	Karnofsky Performance Scale ranges from 0 to 100, where higher scores indicate better functional status.	Day +30, and Day +100 post-transplant
