Gastrointestinal Vascular Malformation Clinical Trial
Official title:
A Randomized, Multicenter, Double-Blind, Placebo-Controlled Study of Efficacy of Thalidomide for Refractory Small Intestinal Bleeding From Vascular Malformation
Gastrointestinal vascular malformation (GIVM), which is an important cause of acute or chronic gastrointestinal bleeding, currently lacks of effective treatment. The investigators' previous study first confirmed thalidomide treatment of GIVM bleeding was safe and effective. This prospective multi-center randomized controlled clinical trial intends to investigate the efficacy of thalidomide to the recurrent small intestinal hemorrhage due to GIVM.
This multi-institutional clinical trial investigates the efficacy of thalidomide to the recurrent small intestinal hemorrhage due to GIVM. Patients with annual average bleeding 4 times or more and lesions located in the small intestine which are not suitable for endoscopic therapy will be randomly assigned to receive A(25mg,Thalidomide，qid), B(25mg, Thalidomide, bid& placebo bid ) or placebo(deferred treatment group) for 4 months. The primary endpoints were the effective response of patients with ≥50% reduction of numbers of bleeding episodes, followed by rate of cases with cessation of bleedin, the difference in blood transfusion, hospitalization, transfusion volume of red cell, average bleeding duration, average hemoglobin level, yearly hospitalization times, average hospital stay and yearly bleeding episodes. This study will be done at 10 centers in China. ;
