Detailed Description
Visit 1 -Screening: Subjects will be screened to the study at the screening visit, PAC-QOL questionnaire will be completed and subject will have a run-in time for a period of 2-3 weeks, assuring 14 consecutive days of eDiary with an average of < 3 SBM per week.
Visit 2 - Baseline: After the run-in period, the subjects will return and eligibility will be re-assessed. Subjects will be randomized to either Vibrant or Vibrant placebo for a treatment period of 8 weeks. Subjects, in both arms, will have their first administration of Vibrant capsule / Vibrant placebo on site at the day of baseline visit and will be instructed on their treatment administration at home and will be requested to ingest the capsules at a specific time of the day. At baseline, subjects will also be trained on how to use the base unit at home.
Subjects will be instructed to complete a simple subject eDiary each day throughout the duration of the study (including the run-in period).
The eDiary will include questions on:
- Daily BM, SBM, CSBM
- Change of their diet, if applicable (NOTE: the protocol will not ask/require the subjects to change anything in his/her diet)
- Change in sympotms as: brisol stool consistancy, straining, bloating, and the other questions in the eDiary
- Medication
- AE (including diarhrea)
The first 2 weeks of treatment will be considered as a subjects' training period.
Visit 3 -after 4 weeks of treatment - an on site visit will take place to evaluate subject's safety and treatment efficacy and additional capsule dispencing.
Visit 4 Final visit -after another 4 weeks of treatment - an on site visit will take place to evaluate subject's safety and treatment efficacy and collect the base unites and remaning capsules. PAC-QOL, Ease of use and TSQM questionnaires will be completed.
During the entire study period, data reporting will be done on an electronic Case Report Form (eCRF) and an eDiary.
Subjects will be asked to refrain from taking any medication or supplement to relieve their constipation, during the entire study period.
Subjects will receive phone calls at least once a week and subject compliance will be monitored throughout the 8 weeks of the study.
Subjects will be authorized to use rescue medication after 3 consecutive days without a bowel movement.
Data about time of activation of the capsules will be automatically registered and transmitted by the base unit for Vibrant capsules

- Clinical evidence of significant respiratory, cardiovascular, renal, hepatic, biliary, endocrine, psychiatric or neurologic disease.
- Presence of cardiac pacemaker or gastric electrical stimulator.
- History of, or current eating disorders, such as anorexia, bulimia, or compulsory overeating.
- 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 transit
- History of Zenker's diverticulum, dysphagia, Barrett's esophagus, esophageal stricture or achalasia
- 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
- Subjects with pelvic floor dysfunction/defecatory disorder, based on subject history
- Participation in another clinical study within one month prior to screening.
- Women who are pregnant or lactating
- Use of any medication for constipation relief during the study, except as rescue medication, as indicated by study rules
- 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
- Subject participated in a previous Vibrant study
- 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
