This bill, titled the Increase Support for Life-saving Endocrine Transplantation Act (ISLET Act), aims to formally classify human cadaveric islets for transplantation as organs . It achieves this by amending the Public Health Service Act to include these islets alongside the pancreas in organ-related regulations. A crucial aspect of the bill is its clarification that human cadaveric islets are explicitly not considered a "drug," "biological product," or "human cells, tissues, or cellular or tissue-based products (HCT/Ps)." This reclassification streamlines their regulatory pathway, potentially facilitating their use in transplantation. The legislation further directs the Secretary of Health and Human Services to update all pertinent regulations within one year and report on this progress to Congress within six months.
