About this study

Official title: A Study on the Safety of Leucine-Restricted Diet in Patients With Gastric Cancer

The primary objectives of this study is o evaluate the safety of a leucine-restricted diet in patients with gastric cancer and determine the impact of a leucine-restricted diet on serum amino acid concentrations in patients with gastric cancer.Besides,we can assess changes in the immune microenvironment of gastric cancer patients following administration of a leucine-restricted diet and observe alterations in body composition of gastric cancer patients after the application of a leucine-restricted diet.

Conditions: Gastric Cancer
Being tested: Leucine-restricted diet.
Keywords: Leucine-Restricted Diet, Gastric cancer
Medical subject headings: Stomach Neoplasms

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Leucine-restricted diet.Dietary supplement
During the preoperative waiting period after hospital admission, study participants received a leucine-restricted diet for three days prior to surgery. Surgical intervention was performed immediately following the 3-day dietary intervention. Postoperatively, patients gradually resumed a regular diet according to standard surgical protocols.

Receives: Dietary Supplement: Leucine-restricted diet.

What is being measured

The primary outcome is the main question the study is designed to answer.

Amino acid concentration
Following leucine-restricted diet intervention, peripheral venous blood was collected from gastric cancer patients to measure serum concentrations of various amino acids, including leucine
Measured: Measurements were performed prior to the initiation of the amino acid-restricted diet and on the day of surgery before the operation
The adverse event of leucine-restricted diet in patients with gastric cancer
This indicator was assessed using the Common Terminology Criteria for Adverse Event(CTCAE) grading system, which comprises five grades (1-5). Grade 1 represents no or mild symptoms, while Grade 5 indicates death
Measured: 6 months after surgery

Secondary outcomes (1)

CD8+ T cell percentage
Following leucine-restricted diet intervention, peripheral venous blood was collected from gastric cancer patients to measure serum concentrations of CD8+ T cell percentage.
Measured: Measurements were performed prior to the initiation of the amino acid-restricted diet and on the day of surgery before the operation.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Leucine-restricted diet. in people with Gastric Cancer, run by Qilu Hospital of Shandong University at 1 site in China.

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 6 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: enrolling by invitation, as of the sponsor's last update on 20 Apr 2026. 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 China. 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.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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?

Amino acid concentration (time frame: Measurements were performed prior to the initiation of the amino acid-restricted diet and on the day of surgery before the operation). 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 NCT07488312, which also lists 15 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 Apr 2026.
