About this study

Official title: Evaluation of the Efficacy of the myDIET Software Tool in the Nutritional Management of Patients With Localized and Resectable Gastric or Esogastric Junction Cancer.

This is a prospective, single-center, single-arm Phase II study evaluating the efficacy of the myDIET software tool in the nutritional management of patients with localized and resectable esogastric junction cancer.

Read the detailed description

Gastric cancer is the 3rd leading cause of cancer mortality worldwide, with a 5-year survival rate of less than 30%. In localised gastric cancer (GC) or cancer of the oesogastric junction (OGJ), the standard treatment consists of gastrectomy and peri-operative FLOT-based chemotherapy (5FU, Leucovorin, Oxaliplatin, Taxotere). However, up to 51% of patients have post-operative complications, and only 60% can benefit from post-operative chemotherapy (at least one course) initiated within 12 weeks of surgery, while 46% receive the full theoretical regimen.

An incomplete adjuvant chemotherapy regimen drastically reduces post-operative prognosis. Undernutrition and sarcopenia increase the occurrence of post-operative complications, length of stay and post-operative readmissions. Undernutrition is an independent risk factor for failure and/or incomplete adjuvant chemotherapy, with an impact on progression-free survival and overall survival. There is a high prevalence of undernutrition in patients with GC/OGJ, estimated at 53-60%, and the proportion of undernourished patients increases significantly postoperatively compared with preoperatively.

Preoperative nutrition and physical activity in sarcopenic patients has been shown to reduce postoperative complications. Early multimodal management, combining nutrition, adapted physical activity and neoadjuvant chemotherapy, is therefore recommended and essential in the perioperative situation. To optimise the nutritional management of patients with operable gastric or oesogastric junction cancer, the CLB teams have developed a computer interface (MyDIET) linked to the myCLB patient portal. This provides semi-personalised monitoring based on self-questionnaires designed to assess and educate patients or their carers about nutritional issues from the outset of oncology treatment, and to prevent the onset or worsening of undernutrition.

For this reason, the sponsor proposes an exploratory study to assess the efficacy of the myDIET digital tool in increasing the proportion of patients with localised CG/OGJ initially treated with neo-adjuvant chemotherapy and who undergo surgery and are able to receive adjuvant chemotherapy within 8 weeks post-operatively.

What participants receive

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

  • myDIET software toolOther

    The tool is based on self-questionnaires completed by the patient. They are mainly filled in using visual analogue scales (from 0-10) or grades of symptoms/toxicities (Grades 0 to 4), based on the CTCAE V5. These scales will cover the following themes: food intake, weight changes, digestive symptoms, taste disorders, pain and fatigue. The system will be able to monitor data changes and the response given will be adapted according to the severity of symptoms:

    • No signs of seriousness: general prevention or treatment documents/advice: toxicity management, nutritional advices targeted on symptoms, on digestive problems, on appropriate physical activity.
    • Presence of signs of seriousness: action to be taken and alert to the coordinating nurse, oncologist or dietician.

    In case of an alert, the coordinating nurse will call the patient back and either manage the symptom, schedule a nutritional consultation to initiate nutritional management, or refer the patient to the oncologist.

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 7 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: looking for participants now, as of the sponsor's last update on 28 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 France. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

Contact Pamela Funk-Debleds, MD (0469856020 ext. +33, pamela.funk-debleds@lyon.unicancer.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Proportion of patients starting adjuvant treatment within 2 months (time frame: 2 months after surgery). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 28 Apr 2026.
