About this study

Official title: Effect of an Essential Amino Acid/Protein Composition on Protein Metabolism

Sarcopenia, a progressive loss of muscle mass, strength and function, is an inevitable natural process of aging. While it may be impossible to completely reverse the progress of sarcopenia, it is well established that intake of dietary protein through essential amino acids (EAAs) and whey protein increases anabolic response. The current study will test if a specially formulated mixture of EAAs and whey protein can maximally stimulate anabolic responses at the levels of whole body and muscle compared to whey protein alone.

Read the detailed description

The product composition is protected by intellectual property. It contains a combination of ingredients designed to stimulate anabolic responses at whole body and muscle and to ultimately induce long-term improvements in muscle function and size. EAAs are the only dietary macronutrients that are required for survival. They are "essential" because the body cannot produce them. There are 9 dietary EAAs while there are 11 dietary non-essential amino acids that are not required in the diet because they can be produced in the body. The composition is based on a blend of 8 of the 9 EAAs. In addition to being the "active" components of dietary protein, EAAs also have the advantage over intact protein including whey protein because free EAAs are absorbed from the intestine more quickly and more completely than amino acids contained in protein, which requires digestion before absorption indicating that intact protein is relatively slowly absorbed. Therefore, the combination of free EAAs and intact protein give not only an immediate response (from the free EAAs) but also a prolonged response (from the intact protein) over time by the slower digestion. The idea of combining a specific formulation of EAAs with an intact protein to obtain both an immediate as well as a more sustained response in protein anabolism is novel. Investigators propose that consumption of the EAA/protein composition will stimulate the net protein balance at the whole body level in a dose-dependent manner. The investigators further propose that the magnitude of increase in the net protein balance will be greater than induced by the consumption of the same amount of whey protein isolate.

Questions about this trial

What is this clinical trial studying?

A study testing 6.3 g of EAAs mixture and whey protein isolate, 12.6 g of EAAs mixture and whey protein isolate and 12.6 g of whey protein isolate in people with Sarcopenia, run by University of Arkansas at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 2 Nov 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 2 Nov 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Protein Anabolism (time frame: Change from 4.5 to 8.5 hours.). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03502941, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Nov 2021.
