safety and feasibility assessment of the bio-electrical one day capsule system in overweight and class i obese participants

Conditions: Overweight and Obesity

Summary: the study represents the first effort to prospectively investigate the melcap's bio-electrical ingestible odc system in human. the study goal is to evaluate the safety and feasibility of ges treatment in stomach and in the small and large bowel during and following the ingestion of the bio-electrical capsule under tight and controlled conditions.

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.
