Clinical Trial Summary

The purpose of the study is to explore the effects of GLP-1 receptor agonist (GLP-1 RA) semaglutide on modulation of taste sensitivity, tongue tissue transcriptome, modulation of neural response in central reward processing regions and gastric emptying rate. In addition, we aim to investigate the associations between semaglutide induced modulation of taste sensitivity, neural responses and gastric emptying with changes in body mass, eating- behavioural pattern, food perception and food intake.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	to investigate the effect of semaglutide on taste perception as change in taste sensitivity detected by chemical gustometry evaluated with "Taste strips" test		Changes in taste perception from baseline up to the end of 12th week.
Primary	CO-PRIMARY END-POINT : to investigate alteration of transcriptomic profile of human tongue tissue as changes in expression level from baseline to follow up after 12 weeks of treatment, measured by RNA sequencing		Change in transcriptomic profile from baseline up to the end of 12th week.
Secondary	Change in neural response to visual food cues and taste task as assessed by functional MRI		Change in neural response to visual food cues and taste task from baseline up to the end of 12th week.
Secondary	Change in eating behaviour by using a Slovenian translation of Three-Factor Eating Questionnaire TFEQ-R18.		Change in eating behaviour from baseline to the end of 12th week of therapy.
Secondary	Change in body weight measured with body weight scale to the nearest 1 kg		Change in body weight from baseline to the end of 12th week of therapy.
Secondary	Change in body fat mass assessed by a Dual Energy X-ray Absorptiometry		Change in body fat mass from baseline to the end of 12th week of therapy.
Secondary	The impact of sema on gastric emptying		Change of gastric emptying from baseline to the end of 12th week of therapy.
