Metformin for Prediabetes in Pregnancy
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to determine if metformin, a medication commonly used for type 2 diabetes, can reduce pregnancy complications in women with prediabetes. Researchers seek to discover if metformin can lower the likelihood of having large babies at birth compared to regular prenatal care. Participants should be pregnant women with prediabetes, as determined by specific blood sugar levels, receiving care at UMass Memorial Medical Center. As a Phase 4 trial, this research explores how this FDA-approved and effective treatment can benefit more patients.
Will I have to stop taking my current medications?
The trial information does not specify if you need to stop taking your current medications. However, if you are already taking metformin for other reasons, you cannot participate in this study.
What is the safety track record for metformin?
Research has shown that metformin is generally safe during pregnancy and does not increase the risk of major birth defects. However, some studies have reported mixed results regarding its effects on birth outcomes. For example, metformin has been associated with a higher chance of early birth and lower birth weight, but these effects can vary based on its use.
The FDA has already approved metformin to help manage blood sugar levels in people with diabetes, indicating it is well-tolerated by many. The current study is in a later stage, suggesting the treatment has been tested in many people before, with few serious safety concerns. Prospective participants in a clinical trial with metformin may find this information helpful in understanding its safety.12345Why are researchers enthusiastic about this study treatment?
Unlike the standard prenatal care for prediabetes, which typically involves lifestyle changes and monitoring blood sugar levels, Metformin offers a proactive pharmacological approach. Metformin is unique because it not only helps in managing blood sugar levels but also improves insulin sensitivity, which is crucial during pregnancy. Researchers are excited about this treatment because it could potentially reduce the risk of gestational diabetes and related complications, offering a new avenue for managing prediabetes in pregnancy safely and effectively.
What evidence suggests that metformin might be an effective treatment for prediabetes in pregnancy?
Research has shown that using metformin during pregnancy can help mothers gain less weight and lower the risk of some pregnancy complications. In this trial, participants in the metformin arm will take a 500 mg tablet orally twice a day, starting at 14 weeks of pregnancy until delivery. Studies have found that metformin leads to fewer negative pregnancy outcomes compared to starting insulin. It can also reduce the chances of low blood sugar in newborns and lessen the need for newborns to be admitted to intensive care. Metformin is already approved for treating certain types of diabetes and effectively controls blood sugar levels. This evidence suggests that metformin could help manage prediabetes during pregnancy.12567

Are You a Good Fit for This Trial?
This trial is for pregnant women receiving care at UMass Memorial Medical Center, who have prediabetes indicated by specific blood sugar tests before the 14th week of gestation. They must be able to consent in writing. It's not for those under 18, with pre-existing diabetes, on metformin already, or if they have liver/renal/heart failure, sensitivity to metformin, a multiple pregnancy or noted fetal defects.Inclusion Criteria
