Nutritional Therapy for Delirium in Elderly Hospitalized Subjects

September 8, 2026 updated by: University of Arkansas
The investigators have developed a proprietary blend of amino acids that they think will help to prevent or reduce the severity of delirium in older adults (60 years and older) who are hospitalized for certain infections. In this study, up to 60 people will be enrolled.20 will be asked to drink this blend twice a day for up to 4 days, and 20 will receive standard treatment in the hospital for the same time period. The other 20 subjects will be non-delirious control subjects who do not consume any study products.

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 will be an interventional pilot study to determine the effectiveness of a specific amino acid supplement developed by the investigators versus standard treatment in mitigating delirium in geriatric patients hospitalized at UAMS for certain infections. Up to 40 delirious and 20 non-delirious subjects (Aged 60 years and older) of any gender or ethnicity will be enrolled (60 subjects maximum). Twenty patients with delirium will be asked to drink this blend twice a day for up to 4 days, and 20 patients with delirium will receive standard treatment in the hospital for the same time period. The other 20 subjects will be non-delirious control subjects who do not consume any study products. All subjects will undergo 2-5 blood draws and 3-7 cognitive assessments while they are admitted to the hospital, depending on study group assignment and discharge date.

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

61 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

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 CAM-S (Confusion Assessment Method-Short) and 4 AT score from baseline to day 3 or up to day 4.
Time Frame: As determined over an up to 4-day intervention duration.
CAM-S and 4 AT is a tool to determine and quantify delirium. Subjects in the non-control arms will undergo this test twice each day. The score ranges from 0-7, with lower numbers being better (little to no signs of delirium).
As determined over an up to 4-day intervention duration.
