CONCORD, Mass., April 30, 2022 (GLOBE NEWSWIRE) — Beta Bionics, Inc. — The results of the multi-center randomized Insulin-Only Bionic Pancreas Pivotal Trial (IO BPPT) were presented today by Dr. Steven J. Russell, Associate Professor of Medicine, Harvard Medical School, at the International Conference on Advanced Technologies & Treatments for Diabetes (ATTD).

Insulin-Only Bionic Pancreas Pivotal Trial Results & Background
The pivotal trial was designed to test the safety and efficacy of the iLet Bionic Pancreas relative to a standard of care control group over a 13-week study period. The standard of care group was comprised approximately one-third each on automated insulin delivery (AID) systems, insulin-pump therapy with continuous glucose monitoring (CGM), and multiple daily injection therapy with CGM. The trial was conducted in a home-use setting and enrolled 440 adults and children aged 6 years and older with type 1 diabetes. The primary analysis of the trial compared the iLet, using Humalog® or Novolog®, versus standard of care in 326 adults…
