NCT04671264

Brief Summary

The safety and efficacy of vibrating capsule (VC) in promoting defecation by mechanical stimulation of the gastrointestinal walls have been elucidated in animal studies and pilot clinical studies. Our study aimed to explore the clinical application of a newly developed smartphone-controlled multi-mode VC in the treatment of functional constipation (FC) on multicentres. Patients referred to gastroenterology outpatient of Changhai Hospital with FC and met the eligible criteria for more than 6 months and with spontaneous complete bowel movement (SCBM) less than 3 times per week within recent 3 weeks were eligible for this study. The study was discussed with patients who satisfied the enrolment criteria and provided written informed consents.

Outcome Measures

Primary Outcomes (1)

  • The proportion of patients with the increasing of SCBMs during treatment period≥1

    Based on diary card, researchers knew the total times of SCBMs during treatment period. The number divided by the treatment days and multiplied by 7 were the mean SCBMs per week in treatment period. Researcher compared the mean SCBMs per week with SCBMs in baseline period. "Spontaneous" suggested that no laxatives and enema were taken within 24 hours before defecation.

    Up to 6 weeks

Secondary Outcomes (8)

  • Increase of SCBMs from baseline to treatment period

    Up to 6 weeks

  • The proportion of patients with the increasing of SCBMs ≥1 in at least 4 weeks

    Up to 6 weeks

  • Increase of SBMs from baseline to treatment period

    Up to 6 weeks

  • Increase of PAC-QOL score from baseline to treatment period

    Up to 6 weeks

  • The proportion of patients with the increasing of PAC-QOL score during treatment period≥1

    Up to 6 weeks

  • +3 more secondary outcomes

Study Arms (2)

VC group

EXPERIMENTAL

Vibrating capsule (VC) was proposed and applied for the patent by professor Liao Zhuan from Changhai Hospital, developed and manufactured by the Ankon Medical Technology Co., Ltd. The system consisted of a vibrating capsule and an external configuration device (ECD). It's 26.7 mm in length, 11.8 mm in diameter and 4.5 + 0.5 g in weight. Each VC has its own semiconductor chip with serial number in order to be recognized and controlled by ECD. VC can be stopped by ECD or mobile-phone application. There was a bidirectional radio frequency communication signal between VC and ECD. In addition, an application (APP) named VCP can be connected to ECD through smart phone to select mode and debug specific parameters for VC. The capsule can be activated by ECD, and then the vibration mode can be controlled by a configurator or an smartphone application.

Device: Sallowing VC during six weeks

Control group

PLACEBO COMPARATOR

The Intervention of control group were similar to VC group except the capsule function. Sham capsule we used in control group which had no function of vibrating.

Device: Sallowing VC during six weeks

Interventions

follow-up was required for at least 6 times, once every two weeks through the whole study. For patients who had no colonoscopy examination within a year, colonoscopy was a must to exclude organic diseases. These included blood routine, blood biochemistry, urine routine, fecal routine, fecal occult blood, thyroid stimulating hormone (TSH), blood pregnancy test and ECG examination. Patients should finish all the examination in the run-in period and at the end of treatment period. Dairy cards were designed mainly for the record of the daily defecation of patients and filled out by the enrolled patients, and the content included date, whether the patients swallow capsules (time), whether the patients discharge capsules (time), defecation, defecation time, degree of defecation exertion(0\~4), BSF scale, complete or incomplete defecation, whether the patient had the sense of anal obstruction, whether manual assistance was applied, and whether first-aid medicine was used (bisacodyl).
