What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study compares two blood sugar targets for overweight or obese women with gestational diabetes. One group aims for stricter goals (fasting under 90 mg/dL, after meals under 120 mg/dL), while the other follows standard targets (fasting under 95 mg/dL, after meals under 140 mg/dL). Researchers will track whether the stricter approach reduces newborn health problems like large birth weight, low blood sugar, jaundice, or breathing issues. The trial plans to enroll 828 participants across multiple centers.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Intensive glycemic targets (stricter blood sugar goals)
What this could lead to
If successful, this could show that tighter blood sugar control reduces newborn complications like large birth weight and jaundice in women with gestational diabetes.
What could go wrong
This is a Phase NA trial, so results are not yet known. Stricter targets may increase the risk of low blood sugar in the mother or be hard to maintain. The benefit for babies is uncertain.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 828 people

The number the study aims to enrol. It can still change while the study runs.

Started

Mar 2022

Expected to finish

Dec 2026

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 to 45 years

Sex

Female participants only

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Pregnant women between the ages of 18-45 * Singleton gestation * Gestational age between 12 0/7-32 6/7 weeks' gestation with gestational diabetes diagnosed during this time frame using either a 50g 1-hr GCT ≥200 mg/dL or two or more abnormal values on a 100g OGTT using the Carpenter-Coustan Criteria * Overweight or obese BMI at the first prenatal visit (BMI ≥25 kg/m2 or ≥23 kg/m2 in Asian Americans) Exclusion Criteria: * Inability or unwillingness to provide informed consent * Inability to communicate with members of the study team, despite the presence of an interpreter * Planned delivery at a non-study affiliated hospital * Known renal disease with a baseline creatinine \>1.5 mg/dL * Significant fetal anomalies diagnosed prior to study enrollment (these will include anomalies such as gastroschisis, spina bifida, complex congenital heart disease, or serious karyotypic anomalies that may lead to early delivery or increased risk of neonatal death) * Oral or IV/IM steroid use within 7 days of study enrollment
