According to the results reported on ClinicalTrials.gov, this trial (NCT03285308) enrolled 336 people with diabetic gastroparesis — a condition where the stomach empties more slowly than normal in people with diabetes. Participants were randomly assigned to receive either a placebo (an inactive treatment) or a drug called relamorelin (10 micrograms), with 167 people starting in the placebo group and 169 in the relamorelin group. The trial ran for 12 weeks and measured changes in four stomach-related symptoms — nausea, abdominal pain, bloating, and feeling full after eating — as well as vomiting episodes. The reported data shows that for the main (primary) symptom score — which combined all four symptoms on a scale of 0 (no symptoms) to 40 (worst possible) — both groups started at similar levels (around 25 points). By week 12, the placebo group's score had dropped by an average of 10.0 points, while the relamorelin group's score had dropped by an average of 9.3 points. For the other primary measure — the proportion of participants who had no vomiting episodes across the final six weeks of the trial — 19.5% of the placebo group and 21.8% of the relamorelin group met this criterion. The reported data for the secondary outcomes shows broadly similar results between the two groups. For nausea improvement, 34.1% in the placebo group and 29.7% in the relamorelin group met the response threshold. For abdominal pain, the figures were 28.0% and 27.9% respectively. For bloating, 26.2% (placebo) and 27.9% (relamorelin) responded, and for feeling full after eating, 22.6% (placebo) and 25.5% (relamorelin) met the response criterion.
