Abstract
Background: Dumping syndrome is a prevalent complication of oesophageal and gastric surgery characterised by early (postprandial tachycardia) and late (hypoglycaemia) postprandial symptoms.
Aim: To evaluate efficacy and safety of the somatostatin analogue, pasireotide in patients with dumping syndrome after bariatric or upper gastrointestinal cancer surgery.
Methods: A single-arm, open-label, multicentre, intrapatient dose-escalation, phase 2 study with 4 phases: screening, 3-month SC (subcutaneous), 3-month IM (intramuscular) and 6-month optional extension IM phase. Primary endpoint was the proportion of patients without hypoglycaemia (plasma glucose = 50% response rate was considered clinically relevant.
Results: Forty-three patients with late dumping were enrolled; 33 completed the 3-month SC phase and 23 completed the 12-month study. The proportion of patients without hypoglycaemia at month 3 (primary endpoint) was 60.5% (26 of 43; 95% confidence interval, 44.4%-75.0%). Improvement in quality of life was observed during SC phase, which was maintained in the IM phase. The proportion of patients with a rise in pulse rate of >= 10 beats/min during OGTT reduced from baseline (60.5%) to month 3 (18.6%) and month 12 (27.3%). Overall (month 0-12), the most frequent (>20% of patients) adverse events were headache (34.9%); diarrhoea, hypoglycaemia (27.9% each); fatigue, nausea (23.3% each); and abdominal pain (20.9%).
Conclusion: These results suggest that pasireotide is a promising option in patients with dumping syndrome after bariatric or upper gastrointestinal cancer surgery.
