A total of 27,022 clinical trials have been recorded in gastrointestinal disorders around the world, with most of them in North America (10,510), particularly the United States (9,615); Europe (7,916), and East Asia (5,501).<\/li><li>Currently, ongoing studies on GI Disorders are 6,434, with North America (2,726), Europe (2,030), and East Asia (1,747), taking the biggest pie.<\/li><li>Having considered this, it&#8217;s also clear that the potential of each region may vary with the type of GI indications being explored in the clinical trials.<\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Regions for Duodenal Ulcer and Dyspepsia Clinical Trials<\/h2>\n\n\n\n<p>While, GI trials include many different therapeutic indications, like ulcers, Crohn&#8217;s disease, IBD, etc., duodenal ulcer and dyspepsia are some of the significantly interesting fields for drug developers. Globally, a total of 108 studies are going on in duodenal ulcer mostly in East Asia (66), Japan (30), Europe (11), and North America (13).<\/p>\n\n\n\n<p>In a recently performed assessment on Credevo, the feasibility of a clinical trial on Sucralfate was explored in duodenal ulcer and dyspepsia. The objective was to select the best regions for site identification and further site selection.<\/p>\n\n\n\n<p>Out of the total 8 countries targeted, 3 countries stood out as the clear winners. These were Poland, Romania, and South Korea.<\/p>\n\n\n\n<blockquote><h3>Poland, Romania and South Korea<\/h3><p><strong>Feasibility of clinical trial on duodenal ulcer and dyspepsia showed that these 3 countries could be very good site for GI clinical trials.<\/strong><\/p><\/blockquote>\n\n\n\n<p>Let&#8217;s look at the details of this feasibility and understand more about these regions.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Target Regions for Feasibility<\/h3>\n\n\n\n<p>A group of countries from Europe, South Asia, South-East Asia, and East Asia was chosen based on the sponsor&#8217;s previous experience, viability, and expected recruitment potential. <\/p>\n\n\n\n<p>These countries included<\/p>\n\n\n\n<ol class=\"wp-block-list\"><li>India,<\/li><li>Indonesia,<\/li><li>Korea (south),<\/li><li>Philippines,<\/li><li>Thailand,<\/li><li>Vietnam,<\/li><li>Poland, and<\/li><li>Romania<\/li><\/ol>\n\n\n\n<h2 class=\"wp-block-heading\">Clinical Trial Design for Feasibility<\/h2>\n\n\n\n<p>The study was designed as a Randomized, Double Masked, Parallel-Group, Placebo-Controlled, Multicentric Study to Evaluate the Efficacy and Safety of Sucralfate Suspension (1g\/10 mL) in Subjects with Dyspepsia Symptoms and Endoscopically Confirmed Active Duodenal Ulcer.<\/p>\n\n\n\n<p>This preliminary trial design was based on an earlier OGD (USFDA) recommendation for conducting a clinical trial for Sucralfate.
