Gustabor Phase 1 - AI-based Creation of a Nutritional Plan to Compensate for Chemotherapy-induced Taste Disorders
A study testing Gustabor server in people with Multiple Myeloma and GI Cancer, run by Wuerzburg University Hospital at 3 sites in Germany.
Trial summary
The study investigates taste disorders that commonly occur during or after cancer treatment, often leading to issues such as malnutrition and treatment discontinuation. Although many non-pharmacological recommendations exist, it is unclear which methods are suitable for which individuals. Read more about this study

About this study
The study investigates taste disorders that commonly occur during or after cancer treatment, often leading to issues such as malnutrition and treatment discontinuation. Although many non-pharmacological recommendations exist, it is unclear which methods are suitable for which individuals. This pilot study aims to use an AI-based, or rule-driven system to generate personalized recommendations based on patients' specific impairments and taste disorder. For the pilot study, the AI will be trained on recipes to create individualized meal plans, helping to identify foods that are likely to be better. The primary endpoint is the assessment of the nutritional intervention as helpful at the second visit within 12 weeks of inclusion.
Read the detailed description
The primary goal of this pilot study is to evaluate the feasibility and perceived helpfulness of a web application using AI-supported, personalized dietary recommendations for patients experiencing taste disorders during or after cancer therapy. The primary endpoint is the assessment of the nutritional intervention as helpful at the second visit within 12 weeks of inclusion.
The study is a prospective, single-arm, non-blinded intervention study with a maximum duration of 12 weeks for individual participants. Participants will be identified on the ward or in outpatient centers during their clinical treatment routine. Study measures and progress assessments will also only take place during the chemotherapy administrations planned as part of the clinical treatment routine or during the follow-up visits.
Data is entered into the Gustabor portal together with study staff. Initially, anthropometric data, eating habits, taste experiences, and taste alterations are recorded via questionnaires. Taste thresholds for sweet, sour, salty, bitter, and umami are then assessed using taste strips. Based on these inputs, an AI system generates personalized recipe recommendations as well as recommendations for actions (e.g., cold meals recommended in case of metallic taste), which are printed and reviewed with the participant. Additionally, participants receive a flyer containing general dietary advice for oncology patients. At the start of the study and again after a period of at least three and up to twelve weeks (timed to fit clinical routines), the Patient-Generated Subjective Global Assessment (PG-SGA) score will be recorded, evaluating weight, symptoms, dietary intake, and physical activity. At the second visit it will be assessed which recommendations were implemented and how helpful they were perceived overall (primary endpoint) and in detail.

What is being measured
The primary outcome is the main question the study is designed to answer.
Patient rating of the nutritional intervention as helpful
Rating of the overall nutritional intervention as helpful at the second visit within 12 weeks after inclusion my means of questionnaire. Rating using a 3-point scale: "Tried it and it didn't help", "Was somewhat helpful" and "Was very helpful".
Measured: Within 12 weeks of inclusion
Secondary outcomes (3)
Patient-generated Subjective Global Assessment (PG-SGA) Score
PG-SGA measures four key areas: weight history, including recent unintentional weight loss; the presence of nutrition-impacting symptoms such as nausea, taste changes, and appetite loss; current food intake compared to normal levels; and functional status, which measures the ability to perform daily activities. Based on the responses, a numeric score is calculated, with higher scores indicating a greater risk of malnutrition and the need for dietary intervention.
Measured: Within 12 weeks of inclusion
Identification of measures that were perceived as helpful
Feedback rating regarding the individual tested measures as helpful / not helpful.
Rating using a 3-point scale: "Tried it and it didn't help", "Was somewhat helpful" and "Was very helpful".
Measured: Within 12 weeks of inclusion
Exploration of correlations between measures and taste perception, tumor type and ongoing tumor therapy
Correlation of the 3-point rated individual measures with individual taste perceptions, tumor type and ongoing tumor therapy
Measured: Within 12 weeks of inclusion
