In DPT-1, parenteral insulin failed to delay or prevent type 1 DM in subjects at elevated risk (as indicated by family history and the presence of islet cell antibodies). These subjects received low-dose subcutaneous Ultralente insulin twice daily, plus annual 4-day continuous IV infusions of insulin. [169] DPT-1 subjects who received oral insulin experienced considerable delays in the onset of diabetes, but once therapy was stopped, their rate of developing diabetes increased to a rate similar to that seen in the placebo group.
