Clinical Trial Summary

Enteral tube feeds are commonly used to meet the entire or partial nutritional requirements of patients with disease-related malnutrition and other conditions who need nutrition support. A large proportion of tube fed patients have increased protein and/or energy requirements due to a higher body mass or increased metabolic stress as a result of disease, surgery or trauma. A high energy, high protein feed has been developed to help meet the needs of such patients. The aim of this study is to investigate the tolerance, compliance and acceptability of this high energy high protein tube feed in adult patients who require nutritional support via tube feeding. 50 eligible patients requiring tube feeding will receive the high energy, high protein feed, according to nutritional requirements for 4 weeks. The primary outcome is nutritional intake, and secondary outcomes include gastrointestinal (GI) tolerance, compliance, acceptability and functional measures. Additional exploratory outcomes of quality of life and micronutrient levels will also be investigated.

Description:

Introduction

The present study will investigate the effect of a high energy, high protein tube feed in patients requiring enteral feeding in the community. The primary objective is to evaluate the effect of daily intake of the high energy, high protein tube feed, in addition to appropriate nutritional management, on total nutrient intakes for 4 weeks. The secondary objectives are to evaluate the effect of daily intake of the feed on gastrointestinal tolerance, compliance, acceptability and functional measures. Additional exploratory measures will be quality of life and micronutrient levels. Enteral tube feeding patients will be recruited by the dietitians responsible for their care, from a variety of dietetic services across the United Kingdom. Potential participants that require a high energy, high protein tube feed will already be known to the Investigating Dietitian or dietetic team at the investigating sites or will be referred to the dietetic service during the duration of the study.

Intervention

Following a 3 day baseline period, each patient will receive the high energy, high protein tube feed for a period of 4 weeks (28 days). The appropriate feed and prescription will be determined on an individual basis by the Dietitian responsible for the patient's nutritional management, based on the patient's clinical requirement and preference and the Dietitian's clinical judgement.

The study feed is classed as a 'Dietary Food for Special Medical Purposes' (EC Directive 1999/21/EC, 1999).

Outcome measures

1. Nutrient intake (energy, protein, fluid and micronutrients)

2. Gastro-intestinal tolerance Gastro-intestinal tolerance will be measured using a standardised gastro-intestinal tolerance questionnaire.

3. Compliance with feed prescription Compliance with feed prescription will be assessed daily throughout the study

4. Acceptability Feed acceptability, such as preference and ease of use will be assessed at the end of study.

5. Anthropometry Weight and height will be measured where possible using standard measures.

6. Patient history Previous nutritional support provided to the patient, previous enteral feeding products prescribed, history of intolerance, the need for a high energy, high protein feed, weight history and other relevant dietetic history.

7. Muscle Function (Hand Grip Strength)

8. Quality of life

9. Micronutrients levels

Statistical aspects

As this is a pilot study no power calculation was undertaken. The sample size of this trial is similar to other published trials of tube feeds in patient populations. In addition to helping to inform clinical practice, the data collected will also be used to support an application to the Advisory Committee of Borderline Substances (ACBS). Recruiting a sample of 50 patients should enable sufficient data to be collected to meet ACBS requirements for the study, while allowing for drop outs during the study period.

Data will be analysed using repeated measures analysis of variance (ANOVA) or t-test where appropriate. Categorical data will be analysed using appropriate methods (e.g. chi-squared). Interim analysis may be undertaken after 30 patients have been recruited. Statistical analysis will be undertaken using IBM SPSS version 23.0 Armonk, New York, USA.

Ethical Considerations

This study will be undertaken in adults with capacity to consent only. In line with the guidance of the Medical Research Council, written informed consent will be obtained for each participant taking part in the study. The investigator will ensure that the study will be conducted in full conformance with the principles of the 'Declaration of Helsinki' (64th WMA General Assembly, Fortaleza, Brazil, October 2013) and with the laws and regulations of the country in which the research is conducted, whichever affords the greater protection to the individual.

Study Monitoring

Monitoring will be organised by the sponsor to evaluate the progress of the study, verify the accuracy and completeness of the Case Report Forms (CRFs) and to ensure adherence to the protocol. Monitoring visits will be scheduled periodically in consultation with the investigator. During monitoring, the study monitor will need access to all patient's study records and raw data used for and generated during the study needed to verify the data in the CRF. If necessary, the investigator must provide the monitor any required background data.

Confidentiality

On recruitment to the study, all participants will be allocated a unique study number, which will be the only identifier on all participant data that will leave the institution involved. For patients consenting to provide blood samples, names will be required to be stored with blood sample results. These results will be accessible by the Investigating Dietitian responsible for the patient's care. For the purposes of data analysis and any publication and dissemination of the data, all results will be analysed and identified using the patient's unique study number only. No identifiable personal data will be published.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in nutrient intakes (energy, protein, fluid and micronutrients)	Nutrient intakes, including the intake of all nutrition provided (including the study feed, other enteral tube feeding, foods, drinks and oral nutritional supplements) will be recorded using 24hr diet recalls. Nutritics® (https://www.nutritics.com/p/references), a dietary analysis program, will be used to calculate energy, protein, micronutrient and fluid intakes.	Measurements will be taken at Baseline (DAY 1) and End of Study (DAY 31).
Secondary	Gastro-intestinal tolerance	Tolerance will be recorded using a standardised gastro-intestinal tolerance questionnaire, measuring incidence and severity of gastro-intestinal symptoms and Bristol Stool Chart© type and frequency of bowel movements, to be completed by the patient.	Gastro-intestinal tolerance will be recorded at baseline (DAY 1, 2 and 3) and on days 4, 5, and 6 of the study (the first 3 days the patient is taking the study feed) and once at the end of each week the patient is taking the feed.
Secondary	Compliance with feed prescription measured via daily feed intake recoding	Compliance will be assessed daily throughout the Baseline period and Intervention period by recording how much study feed was received, to be recorded by the patient or carer. The amount prescribed by the Dietitian will be recorded at the start of the study, and any changes to this prescription also noted. Compliance will be calculated as feed taken as a percentage of feed prescribed.	Every day throughout study completion, 31 days in total.
Secondary	Acceptability	Feed acceptability (preference, ease of use) will be assessed at the end of study by a questionnaire completed by the patient or carer.	End of study (DAY 31)
Secondary	Muscle Function (hand grip strength)	Hand grip strength will be measured, where possible, in all patients in the dominant arm using a handgrip dynamometer. Three measurements will be taken and the mean used for analysis.	Measurements will be taken at Baseline (DAY 1) and End of Study (DAY 31).
Secondary	EQ-5D Quality of life	Quality of life will be measured using the EQ-5D questionnaire.	Measurements will be taken at Baseline (DAY 1) and End of Study (DAY 31).
Secondary	Micronutrient status	In a subset of patients blood samples will be taken and analysed to assess micronutrient status.	Measurements will be taken at Baseline (DAY 1) and End of Study (DAY 31).
