Likewise, aspirin is used by many patients in order to prevent blood clots. Despite their desired benefits, these medicines can cause internal bleeding from the digestive system. The source of this bleeding can be obvious (overt), or obscure and thought to come from the small intestine. Obscure bleeding can show as anemia due to lack of iron in the blood. Small intestine ulcers are now easily diagnosed using an endoscope the size of a big pill (video capsule endoscopy). Small bowel ulcers are not related to stomach acid and therefore do not heal using remedies usually taken to stop acid formation. A different drug, misoprostol, consists of a chemical (prostaglandin) that is usually lacking in patients using aspirin or anti-inflammatory drugs. Misoprostol is licenced to heal stomach and duodenal ulcers in patients using these drugs. Our hypothesis is that misoprostol might be effective in healing small bowel ulcers as suggested by pilot studies; however, such works only included small numbers of patients, did not include control groups and both patients and investigators knew the nature of the tablets used. To test this hypothesis, we propose to compare misoprostol to a dummy tablet. The numbers of subjects to be studied have been calculated using established statistical methods', 'detailedDescription': 'METHODOLOGY:\n\n* Upper gastrointestinal endoscopy and colonoscopy on patients with obscure bleeding and/ or iron deficiency anemia.\n* Video capsule endoscopy on those fulfilling the inclusion criteria\n* Randomization to Misoprostol 200 micrograms or placebo, 4 times each day given for 8 weeks to aspirin/ NSAID users with erosive small bowel lesions.\n* Video capsule endoscopy at 8 weeks to check healing of small bowel lesions.\n* Full blood count at baseline and monthly intervals (0, 4, and 8 weeks)'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '90 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'INCLUSION CRITERIA:\n\nObscure occult gastrointestinal bleeding: presence of one or more of the following:\n\n* Positive fecal occult blood test within last 3 months\n* Iron deficiency anemia (ferritin \\<100 ug/l, hemoglobin \\[Hb\\] 7-12 g/dl \\[female\\] or 7-13 g/dl \\[male\\])\n* Drop in haemoglobin, \\> 2gm/dl from baseline, in the absence of potential or actively bleeding lesion detectable on upper endoscopy or colonoscopy.\n\nNormal/ absence of potentially bleeding lesions on full upper endoscopy and colonoscopy.\n\nTaking low-dose aspirin (75-325m/ day) and/ or NSAIDs\n\nMAIN EXCLUSION CRITERIA:\n\n* Incomplete upper endoscopy or colonoscopy\n* Systemic disease that is unstable at the time of randomisation (unstable vital signs; ongoing non-gastrointestinal investigations; frequent modifications to treatment)\n* Intake of certain drugs: high-dose steroids (\\>7.5-mg prednisolone/ day), cytotoxic drugs, or warfarin.\n* Upper gastrointestinal lesions: oesophageal varices; oesophageal stricture; oesophageal or gastric neoplasms; pyloric stenosis; peptic ulcers; vascular malformations.\n* Colonic disorders: neoplasms or adenomatous polyps; inflammatory bowel disease; vascular malformations; actively bleeding diverticular disease\n* Women planning pregnancy, pregnant or women of child-bearing potential not using two contraceptive methods, one of which must be highly effective \\[implants, injectables, combined oral contraceptives, some intrauterine devices (IUDs), sexual abstinence or vasectomised partner\\]\n* Hypotension: systolic blood pressure \\<100-mm Hg.'}, 'identificationModule': {'nctId': 'NCT02202967', 'acronym': 'MASTERS', 'briefTitle': 'Misoprostol for Small Bowel Ulcers and Obscure Bleeding Due to Aspirin or Nonsteroidal Antiinflammatory Drugs', 'organization': {'class': 'OTHER', 'fullName': 'NHS Greater Glasgow and Clyde'}, 'officialTitle': 'Misoprostol for the Healing of Small Bowel Ulceration in Patients With Obscure Blood Loss While Taking Low-dose Aspirin or Nonsteroidal Antiinflammatory Drugs [MASTERS Trial]', 'orgStudyIdInfo': {'id': 'GN09CA403'}, 'secondaryIdInfos': [{'id': '2013-003187-31', 'type': 'EUDRACT_NUMBER'}]}, 'armsInterventionsModule': {'armGroups': [{'type': 'ACTIVE_COMPARATOR', 'label': 'Misoprostol', 'description': 'Misoprostol', 'interventionNames': ['Drug: Misoprostol']}, {'type': 'PLACEBO_COMPARATOR', 'label': 'Placebo', 'description': 'Placebo', 'interventionNames': ['Drug: Placebo']}], 'interventions': [{'name': 'Misoprostol', 'type': 'DRUG', 'otherNames': ['Cytotec (R)'], 'description': 'Misoprostol oral tablets/ capsules contain 200 mcg of Misoprostol, a synthetic prostaglandin E1 analog', 'armGroupLabels': ['Misoprostol']}, {'name': 'Placebo', 'type': 'DRUG', 'otherNames': ['Dummy drug'], 'description': 'Placebo contains lactose granules', 'armGroupLabels': ['Placebo']}]}, 'contactsLocationsModule': {'locations': [{'zip': 'KA2 0BE', 'city': 'Kilmarnock', 'state': 'Scotland', 'country': 'United Kingdom', 'facility': 'University Hospital Crosshouse', 'geoPoint': {'lat': 55.61171, 'lon': -4.49581}}], 'overallOfficials': [{'name': 'Maureen Travers, PhD', 'role': 'STUDY_DIRECTOR', 'affiliation': 'NHS Greater Glasgow & Clyde, Scotland'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'UNDECIDED'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'NHS Greater Glasgow and Clyde', 'class': 'OTHER'}, 'responsibleParty': {'type': 'SPONSOR'}}}}
