OTSC® – RCT proves OTSC® is superior as first-line treatment in ulcer bleeding

Multicenter, randomized controlled trial shows higher efficacy of OTSC® in obtaining successful hemostasis in peptic ulcers compared to through-the-scope clips (TTSC).

Key findings
• Initial hemostasis rate was 98.4% with OTSC, 78.4% with TTSC (p=0.001)
• Clinical success, defined as the composite of successful initial hemostasis and no evidence of rebleeding within a 30-day period was 96.7% with OTSC vs 74.5% with TTSC (p=0.001).
• 30-day rebleeding rate was low for both OTSC (1.6%) and TTSC (3.9%) (p=0.458)
• Study shows higher efficacy of initial hemostasis as well as overall success of OTSC as first-line treatment for peptic ulcers as compared to TTSC

Study details
• 251 patients in 5 European centers were assessed for eligibility, of which 112 were enrolled in the study
• Patients were randomized to the OTSC group (n=61) or the TTSC group (n=51)
• Only patients with Forrest Ia-IIb gastroduodenal peptic ulcers were enrolled in the study
• In case of no clinical success, the endoscopist was allowed to choose any rescue endoscopic treatment
• Generalized linear model with log-binominal distribution confirmed that OTSC had a 25% higher efficacy compared to TTSC in obtaining successful hemostasis (p=0.003).
