March 15, 2021 updated by: Guy's and St Thomas' NHS Foundation Trust

A Study to Investigate the Effect of Eta-hydroxy-beta-methylbutyrate (HMB) on Skeletal Muscle Wasting in Early Critical Illness

This study aims to investigate the effect of beta-hydroxy-beta-methylbutyrate (HMB) on skeletal muscle wasting, physical function, strength and quality of life in survivors of critical illness. In addition, protein turnover, muscle biology and muscle histology will be investigated.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a double blind, placebo controlled, randomised controlled trial with the primary objective of investigating the effect of HMB on skeletal muscle wasting in early critical illness. Secondary objectives include determining the effect of HMB on skeletal muscle quality, strength, function and quality of life in survivors of critical illness. In addition, the effect of HMB on muscle protein turnover, muscle protein signalling, muscle fibre size and protein:DNA ratio will be investigated in a sub-group of participants.

Eligible participants will be randomised to receive either 3 g/day HMB or 3 g/day placebo within 24 hours of admission to the Intensive Care Unit (ICU). This will be continued until hospital discharge or 28-days, whichever comes first.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 99 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

(i) ≥18 years old (ii) Due to receive enteral nutrition via a nasogastric or naso-jejunal tube as part of routine care (iii) Receiving mechanical ventilation and likely to continue this for more than 48 hours (iv) Likely to remain on the ICU for >7 days (v) Likely to survive intensive care admission. (vi) Admitted to recruiting ICU <24 hours from hospital admission and referring ICU ≥7 days from hospital admission (vii) Agreement obtained from legal representative (viii) Able to comply with protocol and study procedures (ix) No known allergy to IMP or any of its excipients

Participants in other trials can be recruited where protocols are not deemed likely to interfere with endpoints of either study and agreement has been obtained from the respective Chief Investigators.

Since participants in the trial will be abstaining by virtue of their illness, contraception is not required as an eligibility requirement.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in rectus femoris cross-sectional area
Time Frame: Study Day 10
Rectus femoris cross-sectional area will be measured using muscle ultrasound within 24 hours of admission to ICU and then again at study day 10. The difference between these measurements will then be determined.
Study Day 10

Secondary Outcome Measures

Secondary Outcome Measures
