Comparing Insulin Detemir and NPH for Managing Diabetes in Pregnancy

A Phase 2 Open Label Randomized Controlled Trial Determir Vs Neutral Protamine Hagedorn (NPH) In Pregnant Women: DETERMINE Study

Phase 2 Interventional University of California, Los Angeles · NCT05124457

This study is testing whether insulin detemir or NPH is better for managing blood sugar in pregnant women with diabetes and if it affects the risk of low blood sugar in their newborns.

What this trial studies

This study aims to compare the rates of neonatal hypoglycemia in pregnant women with gestational diabetes or type 2 diabetes who are treated with either insulin detemir or NPH. Insulin detemir is already FDA approved for use in pregnant women with type 1 diabetes, while NPH is the only long-acting insulin approved for type 2 diabetes and gestational diabetes. The study will evaluate the safety and efficacy of these two insulin types in managing blood sugar levels during pregnancy, focusing on the potential risks to newborns. By understanding the differences in hypoglycemia rates between these two treatments, the study seeks to improve maternal and neonatal outcomes.

Who should consider this trial

Good fit: Ideal candidates for this study are pregnant women diagnosed with gestational diabetes or type 2 diabetes who require insulin therapy.

Not a fit: Patients who are not pregnant, have type 1 diabetes, or have contraindications to either insulin type will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to safer insulin management options for pregnant women with diabetes, reducing the risk of neonatal hypoglycemia.

How similar studies have performed: Previous studies have indicated that insulin detemir may have a lower risk of hypoglycemia compared to NPH, suggesting potential success for this comparative approach.
