简要总结
To monitor the Whole Gut Transit Time and repeatability of the motility of MD1 capsules in the colon of subjects with known polyps and in healthy subjects. Multi-Center, Open, Home Monitoring, Prospective Study. Up to 100 participants in various phases 2-5 capsules per person, (1 capsule at a time) The primary objective of the study is to monitor the variability of the motility of the MD1 capsules in the Gastrointestinal tract of human subjects with and without polyps in previous Colonoscopy.
详细描述
The subject population in this study will be composed of male and female subjects older than 40 and younger than 80 years old who volunteer for the experiment and qualify with the inclusion / exclusion criteria A total of one hundred (100) subjects will be enrolled in this study. All study participants will be examined by the MD1 capsules, 2-5 capsules per person, one capsule at a time. Efforts will be made to maintain balanced numbers between men and women and even distribution of ages.
The study will be conducted by phases:
A 15-20 Men with polyps in previous Colonoscopy (2-3 repeated ingestions) B. 10-20 Men With no polyps in previous Colonoscopy (1-2 repeated ingestions) C. 15-20 Women with polyps in previous Colonoscopy (2-3 repeated ingestions) D. 10-20 Women With no polyps in previous Colonoscopy (1-2 repeated ingestions) E Same as A-D with the use of prokinetic drugs F. Same as A-D with different type of capsules (lower weight and/or rounded caps on both sides).
The total duration of the study for each subject is two-four weeks. Each subject will ingest 2-5 capsules, one at a time, with at least 1 week apart between repeated ingestion
- st Visit (phone interview) - Each subject will receive a comprehensive explanation regarding the study nature. During this process, and per ethical committee approval, subjects may be asked several questions (over the phone) regarding their medical background for preliminary assessment of eligibility.
- nd Visit - Once informed consent is obtained, a thorough evaluation of subject's eligibility will be performed based on inclusion / exclusion criteria.

结局指标
主要结局
Measure the variability of the motility (Whole gut transit time from ingestion to excretion {hours}) of the MD1 (Motility dummy 1) capsules in the Gastrointestinal tract of human subjects with and w/out polyps in previous Colonoscopy.
时间窗: 12 months
All participating subjects will be consented for multiple measurements. In selected subjects the experiment will be repeated with same type MD1 capsule but w/out the drug, to compare the effect of the drug on the motility and the instantaneous speed during contractions. These subjects will be selected according to their results in the first round, ease of adjustment to the monitoring routine, retrieval of the excreted capsules and lack of any side effects or complains. The repeated procedure will be at least 1 week apart and will be approved by the investigator only after positive identification of the excretion of the first capsule. Naturally, there is no need to repeat the colonoscopy procedure The repeated tests will be conducted according to the same protocol. There are no additional safety issues in the re-ingestions tests since the 1st capsule has to be excreted and retrieved few days before the repeated experiment starts
