Design outcomes

Primary

MeasureTime frame
Timepoint(s) of evaluation of this end point: After 4 weeks of treatment;Main Objective: The primary objective of the study is to investigate whether treatment with melatonin has an alleviating effect on LARS symptoms. ;Secondary Objective: The secondary objective of the study is to investigate how treatment with melatonin affects movements, other patient reported symptoms, quality of life, depression, anxiety, sleep disturbances, motilin levels, and microscopic changes in rectal mucosa. ;Primary end point(s): The LARS Score

Secondary

MeasureTime frame
Secondary end point(s): • Daily registration of bowel function • Quality of life measured by EORTC Quality of Life Questionnaire (QLQ-C30 & QLQ-CR29) • Measure Yourself Medical Outcome Profile (MYMOP) • Anxiety measured by Hospital Anxiety and Depression Scale (HADS-A) • Depression measured by Hospital Anxiety and Depression Scale (HADS-D) • Sleep and circadian outcomes measured by actigraphy. • Insomnia severity measured by Insomnia Severity Index (ISI) • Sleep diary • Safety, adverse events, and reactions and compliance by a standardized interview • Blood tests measuring melatonin and difference in gene expression by nanoString • Pathological assessment of the rectal mucosa • Differences in gene expression of the rectal mucosa by NanoString • Assessment of levels of motilin and motilin receptors ;Timepoint(s) of evaluation of this end point: During the 4 weeks of treatment: • Daily registration of bowel function, actigraphy, and sleep diary After 4 weeks of treatment • All other end-points
