Clinical Trial of Encapsulated Islet Cells

On August 16th, CytoTherapeutics Incorporated announced the commencement of its FDA-approved trial involving polymer-encapsulated islet cells. The trial is designed to establish that their semi-permeable membrane can allow enough nutrients through to keep the encapsulated cells alive while protecting them from destruction without the use of immunosuppressive drugs. The implant will be tested in people with type I and type 2 diabetes, as well as in a nondiabetic control group. The trial will be conducted at Washington University School of Medicine in St. Louis, and results of the 4 month viability study are expected by the end of 1993.
