Clinical Trial Summary

This placebo cross-over trial aims to study the effect of the oral intake of an essential amino-acid 5-OH tryptophan, the precursor of serotonin, on the fatigue scores in IBD patients in deep clinical and biological remission.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in Visual Analog Scale (VAS) after intervention	Patients are asked to indicate their fatigue level on a VAS-scale from 0 to 10, where 0 represents no fatigue and where 10 indicates the patient suffers from severe fatigue.	weekly, 16 weeks
Secondary	Changes in Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) score	The questionnaire is a self-assessment that need to be completed without external help. The FACIT-F questionnaire measures the fatigue of the patient and will be filled in at week 0, week 8 and week 16. The FACIT Fatigue scale ranges from 0 to 52, with high scores indicating higher levels of fatigue.	week 0, week 8 and week 16
Secondary	Changes in short Depression Anxiety and Stress Scale (DASS21)	The questionnaire is a self-assessment that need to be completed without external help. The DASS questionnaire measures depression and anxiety and will be filled in at week 0, week 8 and week 16. The questionnaire contains 7 items per scale, the maximum score for depression, anxiety and stress will be 21. The higher the score of the questionnaire, the more the patient suffers from depression, anxiety and stress.	week 0, week 8 and week 16
Secondary	Change in Adapted International Physical Activity Questionnaire (IPAQ)	The adapted IPAQ questionnaire measures the physical activity and will be filled in at week 0, week 8 and week 16.	week 0, week 8 and week 16
Secondary	Changes in serum 5-HydroxyTryptophane (5-HTP) by treatment	The possible effect of Levotonine administration on the serum 5-HTP levels will be measured.	Week 0, week 8 and week 16
Secondary	Changes in serum 5-hydroxyindoleacetic acid by treatment	The possible effect of Levotonine administration on the serum 5-hydroxyindoleacetic levels will be measured.	Week 0, week 8 and week 16
Secondary	Changes in serum serotonin levels by treatment	The possible effect of Levotonine administration on the serum serotonin levels will be measured.	Week 0, week 8 and week 16
Secondary	Changes in serum melatonin levels by treatment	The possible effect of Levotonine administration on the serum melatonin levels will be measured.	Week 0, week 8 and week 16
Secondary	Changes in faecal microbiome/metabolome	since the intestinal bacteria can process tryptophane, changes in the faecal microbiome/metabolome can be possibly caused by the administration of levotonine.	Week 0, week 8 and week 16
