Overweight and Obesity | Device: ODC system (type 1 capsule) Device: ODC system (type 2 capsule) | Not Applicable |
The problem of obesity in the adult population requires the exploration and development of new, safe and effective therapies to combat increasing growth. A novel Implantable Gastric Electrical Stimulation (GES), MEASTRO(R) Rechargeable System, has been recently approved by the American Food and Drug Administration (FDA) for use in weight reduction in patients aged 18 years through adulthood who have a Body Mass Index (BMI) of 40 to 45 kg/m2 with one or more obesity related co-morbid conditions, and have failed at least one supervised management program within the past 5 years.
Melcap System Ltd. has developed an innovative ingestible capsule system device that uses GES for the treatment of overweight and obesity. The system is intended to suppress hunger, reduce appetite, increase satiation and promote weight reduction in overweight and class I obese adults who have a Body Mass Index of 27 kg/m2 to 34.9 kg/m2 with no related co-morbid conditions.
The study is a FIH prospective, open label, randomized study. It will include a 3 days screening period and 4 days treatment session under a close supervision and follow up. Each subject will ingest a total of 2 capsules (ODC) on the first and the third day of the study. The total duration of subject participation including the termination visit will be eight days.
The study will be conducted at a single medical center, Meir Hospital, Israel.

---|---|
Experimental: Gastric electrical stimulation with type 2 ODC
Safety and feasibility assessment of the ODC system (type 2) capsule during and following gastric electrical stimulation protocol.
|
Device: ODC system (type 2 capsule)
ODC (one day capsule) type 2 is ingested by a subject and passes through the gastrointestinal tract. Electrical stimulation is the transferred from the capsule to the surrounding GI tissues. The capsule is excreted from the body through the intestinal tract in a natural manner with bowel movement. |
Experimental: Electrical stimulation with type 2 ODC
Safety and feasibility assessment of the ODC system (type 2) capsule during and following small and large bowel electrical stimulation protocol.
|
Device: ODC system (type 2 capsule)
ODC (one day capsule) type 2 is ingested by a subject and passes through the gastrointestinal tract. Electrical stimulation is the transferred from the capsule to the surrounding GI tissues. The capsule is excreted from the body through the intestinal tract in a natural manner with bowel movement. |
Experimental: Electrical stimulation with type 1 ODC
Safety and feasibility assessment of the ODC system (type 1 capsule) during and following small and large electrical stimulation protocol.
|
Device: ODC system (type 1 capsule)
ODC (one day capsule) type 1 is ingested by a subject and passes through the gastrointestinal tract. Electrical stimulation is the transferred from the capsule to the surrounding GI tissues. The capsule is excreted from the body through the intestinal tract in a natural manner with bowel movement. |

- Response to nutrient drink test [ Time Frame: Day #3 of the screening period and and day #4 of the treatment period ]Determination of the maximum tolerable drinking volume followed by postprandial symptoms measurement
- Appetite-related hormone [ Time Frame: Day #1 and Day #3 of the treatment period ]Evaluation of appetite- related hormones levels change as a result of the stimulation applied
