Overview

Fructosin® is a medical device for use in fructose intolerance. In this uncontrolled posdt market clinical follow up (PMCF) study, the safety and efficacy of oral supplementation of Fructosin® in fructose intolerance will be investigated. The study participants will be informed about the nature and scope of the study during a preliminary examination (screening) and a declaration of consent will be obtained. In addition, it is determined whether fructose intolerance is present. This is determined by means of the aCPQ test. Subsequently, the patients fill out symptom questionnaires (IBS-SSS, IBS-QoL, 1-week symptom questionnaire). After the eligibility check, a 14-day phase of monitoring and documentation of symptoms and complaints without taking Fructosin® (observation phase) takes place. At visit 1, the patients receive the Fructosin® capsules, which they take as needed, but no more than 2 x 3 times a day with fruit meals. The intake phase runs over a period of 28 days (4 weeks) during which the study participants observe and evaluate gastrointestinal symptoms with the help of the 1-weekly symptom questionnaire. In addition, the daily fructose consumption (fruit, fruit juices, smoothies) and the amount of Fructosin® capsules taken are documented in a diary.

Outcomes

Primary Outcomes

Safety of FRuctosin

Adverse events are recorded by the study participants by means of a diary and asked about by the study investigators at the end of the study (final visit). At the final visit, the subjects are asked about any changes in their health status. Any symptoms that occur that go beyond the symptoms of fructose intolerance are documented as adverse events (AE). All distinguishing features between adverse and serious adverse events, defined in accordance with the ICH/GCP guidelines, are queried and documented in the electronic case report form. AE are documented in source documents and include description, time period, treatment, intensity (1 mild, 2 moderate, 3 severe) and outcome (1 recovered, 2 recovered with limitation, 3 not yet recovered, 4 unknown), as well as severity (yes/no) and possible association (0 no association, 1 unlikely, 2 possible, 3 probable, 4 certain). The assessment of the association of AEs with the study medication is made by the investigator.
