Clinical Trial Summary

The objectives are to assess the efficacy and safety of Vibrant capsule administered twice a week


Description:

The study is a prospective, randomized, multicenter, adaptive design, double blinded clinical study, to evaluate the efficacy and safety of Vibrant Capsule vs. placebo in relieving constipation in subjects with Chronic Idiopathic Constipation. Two arms will be assessed (at a ratio of 1:1 of Vibrant Treatment vs. placebo): - Vibrant Capsule administered twice a week (Monday and Thursday) - Placebo Capsule administered twice a week (Monday and Thursday) Subjects will come for 4 visits: Screening (visit 1), baseline (visit 2), after 4 treatment weeks from baseline (visit 3) and after 8 treatment weeks from baseline (Final visit , visit 4). A total of 8 treatment weeks. During the entire study period subjects will be asked to refrain from taking any medications or supplements to relieve their constipation. Subjects will be authorized to use rescue medication after 3 consecutive days without a bowel movement

Clinical evidence of current and significant gastroparesis 5. Use of any of the following medications: - Medications that may affect intestinal motility (including but not limited to prokinetics, anti-Parkinsonian medications, opiates, opioids, Verapamil, Nifedipine, iron, magnesium supplements, Tricyclic antidepressants (TCAs), Heparin, Warfarin and Baclofen. - With the exception of antidepressants (other than TCAs), thyroid or hormonal replacement therapy, when the subject has been on a stable dose for at least 3 months prior to enrollment. 6. Clinical evidence of significant respiratory, cardiovascular, renal, hepatic, biliary, endocrine, psychiatric or neurologic disease. 7. Presence of cardiac pacemaker, gastric electrical stimulator or any electrical implanted device. 8. History of, or current eating disorders, such as anorexia, bulimia, or compulsory overeating. 9. Diagnosis of mega-rectum or colon, congenital anorectal malformation, clinically significant rectocele, history of intestinal resection (with an exception for appendectomy, cholecystectomy and inguinal hernia repair), history of bariatric surgery or evidence of any structural abnormality of the gastrointestinal tract that might affect capsule's transit 10. History of Zenker's diverticulum, dysphagia, esophageal stricture, eosinophilic esophagitis or achalasia 11. Chronic use of non-steroidal anti-inflammatory drugs (NSAIDs): chronic use is defined as taking full dose NSAIDs more than three times a week for at least six months. Subjects on cardiac doses of aspirin may be enrolled in the study 12. Subjects with pelvic floor dysfunction/defecatory disorder, based on subject history 13. Participation in another interventional clinical study within one month prior to screening. 14. Women who are pregnant or lactating 15. Use of any medication for constipation relief during the study, except as rescue medication, as indicated by study rules 16. Inability to use an electronic daily Diary (on a computer, phone application, tablet or other electronic device) to report bowel movements, symptoms and medication usage 17. Subject participated in a previous Vibrant study 18. Subjects planning to undergo MRI during the study 19. Any known allergy to soybean, beeswax, Calcium Carbonate, Gelatin, Glycerin or Titanium dioxide 20. Any other condition which in the opinion of the investigator may adversely affect the safety of the subject or would limit the subject's ability to complete the study

Outcome

Type Measure Description Time frame Safety issue
Primary CSBM 1 success rate: Increase of at least one Complete Spontaneous Bowel Movement (CSBM) a week from BL. CSBM1 success rate, defined as an increase from the run-in period of at least one weekly Complete Spontaneous Bowel Movement (CSBM) during at least 6 of the 8 weeks of treatment up to 8 weeks of treatment
Primary Increase of at least two Complete Spontaneous Bowel Movement (CSBM) a week from BL CSBM2 success rate, defined as an increase from the run-in period of at least two weekly Complete Spontaneous Bowel Movement (CSBM) during at least 6 of the 8 weeks of treatment up to 8 weeks of treatment
Primary adverse events Safety endpoints include all adverse events related and unrelated to the study treatment up to 10 weeks
Secondary Straining based on the subject's assessment recorded in daily diaries (Scale range from 0- No straining to 10 Unbearable straining) Change from baseline in average straining based on the subject's account in daily diary reports.
