Role of Pregnancy Related Hormones in Lowering the Insulin Requirement in Pregnant Women With Type 1 Diabetes

Summary

This is a randomized, double-masked, placebo-controlled, single-center study to evaluate stimulated C-peptide secretion after exogenous administration of mild immunosuppression and growth-promoting factors to women with preexisting T1DM who had a decline in insulin requirement or had detectable C-peptide during a previous pregnancy. Fifteen subjects will be enrolled and randomly assigned in a 2:1 ratio to either active treatment or placebo in a parallel group design. Participation for individual subjects will consist of an initial Screening Visit, a 2-week baseline period, a Baseline Visit, visits at week 2 and 4 of the treatment period, a visit at the end of the treatment period (week 6), and a follow-up visit 2 weeks after study treatment discontinuation. Subjects will receive either active treatment or matching placebo of estradiol 1 mg every 8 hours; medroxyprogesterone 2.5 mg every 24 hours; hydrocortisone 2.5 mg every morning, 1.25 mg every afternoon, and 1.25 mg at bedtime each night; and growth hormone 2 mg once a day).
