Brief Summary:
The study is a prospective, randomized, multicenter, adaptive design, single blinded, placebo-controlled study, to evaluate the efficacy and safety of Vibrant Capsule vs. placebo in relieving constipation in subjects with Chronic Idiopathic Constipation.

Condition or disease Intervention/treatment Phase
Chronic Idiopathic Constipation Device: Vibrating capsule Not Applicable

Detailed Description:

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

Three arms will be assessed:

  • Vibrant Capsule mode A administered 5 times per week
  • Vibrant Capsule mode B administered 5 times per week
  • Placebo Capsule administered 5 times per week The difference between the 2 operating modes is in the vibrating sequence during the capsule's operating time.

Primary Outcome Measures :
  1. CSBM1 & CSBM2 Success Rate [ Time Frame: 8 weeks of treatment ]

    defined as number of subjects with 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, and CSBM2 success rate, defined as number of subject with 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.

    The study will be deemed successful if either the CSBM1 or the CSBM2 success rate is statistically significantly higher in the active arm that was continued after the interim analysis, than in the placebo arm


  2. Adverse event [ Time Frame: up to 11 weeks ]
    Safety endpoints include all adverse events related and unrelated to the study treatment in all 3 arms


Secondary Outcome Measures :
  1. straining using VAS scale (0-10) for straining where "0" is no straining and "10" is unbearable straining [ Time Frame: 8 weeks of treatment ]
    Change from baseline in average straining in all 3 arms

  2. consistency using the bristol stool scale (1-7) where 1 = Separate hard lumps, like nuts (hard to pass) and 7 =watery, no solid pieces, entirely liquid [ Time Frame: 8 weeks of treatment ]
    Change from baseline in average stool consistency, using the Bristol Stool Scale in all 3 arms

  3. bloating sing VAS scale (0-10) for bloating where 0=No bloating and 10=Unbearable bloating [ Time Frame: 8 weeks of treatment ]
    Change from baseline in average bloating in all 3 arms


Other Outcome Measures:
  1. CSBM1 [ Time Frame: 8 weeks of treatment ]
    CSBM1 success rate when using the data from the two active arms together

  2. CSBM2 [ Time Frame: 8 weeks of treatment ]
    CSBM2 success rate when using the data from the two active arms together

  3. SBM [ Time Frame: 8 weeks of treatment ]
    SBM success rate, defined as number of subjects with an increase from baseline period of at least one weekly Spontaneous Bowel Movement (SBM) during at least 6 of the 8 weeks of treatment

  4. Rescue [ Time Frame: 8 weeks of treatment ]
    The number of incidence of Rescue Medication use during the treatment period

  5. Change in SBM [ Time Frame: 8 weeks of treatment ]
    Change from baseline in weekly number of Spontaneous Bowel Movement (SBM)

  6. SBM after firs dose [ Time Frame: 8 weeks of treatment ]
    Number of subject with SBM during the first 24 hours after first dose in all 3 arms

  7. Abdominal gas using VAS score (0-10) where 0=No abdominal gas and 10=Unbearable abdominal gas [ Time Frame: 8 weeks of treatment ]
    Change from baseline in average abdominal gas in all 3 arms

  8. Abdominal pain using VAS scale (0-10) for Pain , where 0=no pain and 10= Unbearable pain [ Time Frame: 8 weeks of treatment ]
    Change from baseline in average abdominal pain in all 3 arms

  9. Abdominal discomfort using VAS scale (0-10) where 0= no discomfort and 10 = Unbearable discomfort [ Time Frame: 8 weeks of treatment ]
    Change from baseline in abdominal discomfort in all 3 arms

  10. Time to occurrence [ Time Frame: 8 weeks of treatment ]
    Time to occurrence of spontaneous bowel movement after first capsule activation

  11. TSQM - scale is 0-100 . where 0 is not satisfied and 100 is very satisfied [ Time Frame: 8 weeks of treatment ]
    Treatment satisfaction score using the TSQM (Treatment Satisfaction Questionnaire for Medication)

  12. PAC-QOL - scale is 0-100 . where 0 is not constipated and 100 is very constipated [ Time Frame: 8 weeks of treatment ]
    Change from baseline in quality of life using the PAC-QOL (Patient Assessment of Constipation Quality of Life) questionnaire
