Efficacy Safety and Tolerability of Multiple Doses of Oshadi Icp (Oshadi Oral Insulin) in Patients With Type 1 Diabetes Mellitus - Phase II Clinical Study

Diabetes mellitus (DM) is a chronic disease of carbohydrate, fat, and protein metabolism caused by an absolute or relative deficiency of insulin, an anabolic hormone. The current methods of insulin therapy for diabetic patients are multiple daily injection therapy and continuous subcutaneous insulin infusion with an external pump. This rout of administration may lead to hyperinsulinemia as insulin is administered in a non physiological way, targeting mainly extra hepatic tissues (muscle, fat). A method of providing insulin without the need for injections has been a goal in drug delivery.

Oshadi Drug Administration Ltd. has developed oral carrier for proteins based on biochemistry and quantum theory of biochemical reactions. The carrier enables the absorption of proteins from the gastrointestinal tract in their full structure. Oshadi has also developed the Oshadi Icp - insulin, proinsulin and C-peptide in Oshadi carrier, administrated orally. This study was design in order to evaluate the safety and feasibility of multiple administrations of Oshadi Icp for home use. The study will be a multiple-dose, open-label non-randomized study in patients with Type 1 diabetes, with periodic dose adjustments. The study will include 4 weeks of multiple-dose administration of Oshadi oral insulin (Oshadi Icp) at home and in study center for the determination of the efficacy, safety and pharmacodynamic effects of Oshadi Icp.
