About this study
Official title: Supplementation of a Leucine-Enriched Dairy Protein Blend: Chronic and Acute Metabolic Responses in Young Men and Women
It is well known that dietary protein transiently stimulates muscle protein synthesis (MPS) whereby changes in MPS in response to feeding may be regulated by specific downstream target proteins of mammalian target of rapamycin signaling, such as S6K1, rpS6, and eIF2B. A meal deficient in protein, however, does not increase the rate of MPS because a rise in the bioavailability of amino acids does not occur. In addition, the source of dietary proteins has been shown to impact postprandial blood levels of amino acids. The concept that certain types of proteins are "fast acting" or "slow acting" has been shown to affect the postprandial profile of amino acids appearing in the systemic circulation. Native whey and micellar casein are both dairy proteins that contain a similar amount of essential (EAA), but blood EAA levels increase faster and to a higher level after the consumption of whey protein. Differences in gastric emptying, digestion and absorption kinetics between micellar casein and native whey are the underlying factors. Nonetheless, micellar casein protein has been shown to protract MPS in humans. Despite the significant amount of information gained with respect to both of these protein sources, the effects of combinatorial formulations on the postprandial profile of amino acids appearing in the blood is less well known.
Read the detailed description
In a cross-over, randomized controlled trial, 10 healthy young participants (5 men and 5 women) will be recruited to undergo exercise resistance training randomized to habitual diet or habitual diet and supplementation (2 x per training session). For two of the training sessions the investigators will utilize a uni-lateral resistance exercise model to identify the acute effects of exercise and exercise + supplementation on the integrated rate of myofibrillar MPS within subject. This model enhances statistical power and eliminates between-subject differences impacting our outcomes. Throughout the study participants will record their macronutrient dietary intake. In addition, baseline body composition will be assessed with dual-energy x-ray absorptiometry.
Visit 1 (Day -7): Familiarization, strength testing and baseline body composition One week before the exercise trial, the investigators will ask participants to visit McMaster University to undergo a familiarization session with the exercise equipment and to perform 3-5 repetition maximum strength testing. This will allow the investigators to calculate the resistance (weight) participants will lift in their upcoming training sessions. The investigators will also perform a body composition scan using a dual-energy x-ray absorptiometry (DXA), assess participants' height and weight, and administer daily food logs with instructions to assess their habitual diet.
Visit 2 (Day 0): D2O administration and resting blood and saliva sampling One week after the familiarization visit, the investigators will ask participants to come to McMaster University in a fasted state and receive a dose of doubly labelled water D2O equal to 0.8mLs/kgBW and every hour for 3 hours after providing a blood and saliva sample. D2O is a safe, and widely used stable isotope, used to effectively measure the rate at which participants' muscle grow.
Visits 3 and 7 (Days 1 and 7): Resistance training program and muscle biopsy On these days participants will come to the lab in the morning following their habitual diet routine and will have a resting biopsy, blood and saliva samples taken. Next, participants may be asked to consume the supplement but will be asked to drink a small amount of D2O. Finally, participants will perform a combination resistance style exercise training session and immediately following training may be asked to consume the supplement.
Visit 4, 5, 8 \& 9 (Days 2, 3, 8, 9): Resistance training program On these days participants will come to the lab in the morning following their habitual diet routine and have a saliva sample taken. Next, participants may be asked to consume the supplement but will be asked to drink a small amount of D2O. Finally, participants will perform a combination resistance style exercise training session and immediately following training participants may be asked to consume the supplement.
Visits 6 and 10 (Days 4 and 10): Uni-lateral acute training session and muscle biopsy On these days participants will come to the lab in the morning following their habitual diet routine. First, participants may be asked to consume the supplement immediately before performing a uni-lateral acute resistance training session. Participants will be asked to drink a small amount of D2O but only during Visit 6 (Day 4). Immediately following training, participants may be asked to consume the supplement. One hour following exercise participants will have a muscle biopsy, blood and saliva samples taken.
Days 5 and 6 (see attached study timeline): Washout period The investigators will ask that participants drink one aliquot of D2O on day 5 and one aliquot of D2O on day 6. One hour after participants drink the aliquot of D2O the investigators ask that participants take their own saliva sample at home (D2O aliquots and a sampling kit will be provided with instructions).

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
It is well known that dietary protein transiently stimulates muscle protein synthesis (MPS) whereby changes in MPS in response to feeding may be regulated by specific downstream target proteins of mammalian target of rapamycin signaling, such as S6K1, rpS6, and eIF2B. A meal deficient in protein, however, does not increase the rate of MPS because a rise in the bioavailability of amino acids does not occur. In addition, the source of dietary proteins has been shown to impact postprandial blood levels of amino acids. The concept that certain types of proteins are "fast acting" or "slow acting" has been shown to affect the postprandial profile of amino acids appearing in the systemic circulation. Native whey and micellar casein are both dairy proteins that contain a similar amount of essential (EAA), but blood EAA levels increase faster and to a higher level after the consumption of whey protein. Differences in gastric emptying, digestion and absorption kinetics between micellar casein and native whey are the underlying factors. Nonetheless, micellar casein protein has been shown to protract MPS in humans. Despite the significant amount of information gained with respect to both of these protein sources, the effects of combinatorial formulations on the postprandial profile of amino acids appearing in the blood is less well known.

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing Leucine-enriched protein and Habitual diet only in people with Dietary Modification and Diet Habit, run by McMaster University at 1 site in Canada.
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 6 inclusion and 11 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 20 Jun 2024. 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 Canada. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Integrated Muscle Protein Synthetic Rate (time frame: 10 days). 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 NCT03796897, which also lists 9 linked publications.
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 20 Jun 2024.
