CTIS Part I — objectives, methods, condition coding

Main objective

Scope: Others

To evaluate whether coadministration of adjunctive therpay affects tolerability of semaglutide in overweight non-diabetic patients.

Secondary objectives 4

  1. To evaluate compliance with semaglutide.
  2. To assess the subjective tolerability of semaglutide.
  3. To explore the potential modulation of appetite and body weight change.
  4. To assess the occurrence of side effects.

Endpoints

Primary and secondary outcome measures (English text)

Primary endpoints 1

  1. Semaglutide treatment tolerability operationalised as the severity of nausea measured using the 0–10 numeric rating scale (NRS) during the first 96 hours after semaglutide administration.

Secondary endpoints 5

  1. The period mean of the daily well-being according to numerical rating scale compared between treatment groups.
  2. Patient self-reported usage of daily oral study medication.
  3. Change in body weight from the baseline
  4. Change in appetite
  5. Incidence and severity of other side effects (vomiting, constipation, diarrhoea, abdominal pain, dizziness, fatigue, headache)
