Greenville, North CarolinaAges 18–45 - NCT04786587Recruiting
Study of alcohol reporting during pregnancy
This study looks at how alcohol use is reported during pregnancy. It may help improve how pregnant people share this information during prenatal care.
LilleAges 18 years+ - NCT04661553Recruiting
Special camera test to spot early cervical changes in pregnancy
This trial tests a detailed “polarimetric colposcopy” camera exam to better detect early changes in the cervix during pregnancy. Results may help guide closer monitoring in pregnancy, especially if there are signs that the cervix may start to change too soon.
Le Kremlin-Bicêtre, FranceAges 18 years+ - NCT04394806Recruiting
Fasting and meal-fat study in early pregnancy
This study looks at how fasting and eating affect a pregnancy’s fat levels in the belly and liver. It may help researchers understand how maternal metabolism could impact baby and pregnancy health.
Aurora, ColoradoAges birth–39 years - NCT04405700Recruiting
Tracking birth outcomes and birth defects after delivery
This study follows pregnant people and their babies to better measure adverse outcomes and possible congenital (from birth) conditions. It may help improve how birth risks and birth defects are identified and recorded at the clinic.
EldoretAges Any age - NCT04421768Recruiting
Training for cervical exams in labor and delivery care
This trial studies whether a structured training program helps healthcare staff perform cervical exams more effectively during labor. It may improve how labor and delivery care is delivered at the hospital.
Winston-Salem, North CarolinaAges Any age - NCT04356326RecruitingPhase 3
Aspirin to prevent complications in pregnancy with chronic high blood pressure
This trial studies whether taking acetyl salicylic acid (aspirin) during pregnancy can reduce problems caused by chronic high blood pressure. It focuses on pregnant people already known to have high blood pressure before or early in pregnancy.
BordeauxAges 18 years+ - NCT04109846Recruiting
Embryo transfer using aneuploid or mosaic embryos during pregnancy
This trial looks at pregnancy and baby outcomes when embryos that have chromosome differences (aneuploidy or mosaic embryos) are transferred, especially when no other embryos are available. It may help people understand the risks and expected outcomes in situations where options are limited.
Sunnyvale, CaliforniaAges 18–55 - NCT03992729Recruiting
Study tracking pregnancy outcomes after tildrakizumab use
This study follows pregnant people who took tildrakizumab to understand pregnancy outcomes and safety. It also compares them with pregnant people with the same underlying disease who did not take tildrakizumab during this pregnancy.
San Diego, CaliforniaAges Any age - NCT03659708Recruiting
Study to prevent dangerous blood clots during pregnancy
This study looks at pregnancy-related risk for a dangerous blood clot in the leg or lung (venous thromboembolism). It focuses on pregnant people who already have a higher-than-average risk and wants to see how to manage that risk safely.
BronAges 18–50 - NCT02895165Recruiting
Pregnancy and fertility registry for people with breast cancer
This trial is a registry that collects information about pregnancy and future fertility in people with breast cancer. It may help doctors better understand outcomes and care options for patients in these situations by studying real-world experiences.
Asti, AstiAges 18–45 - NCT02471378Recruiting
Testing a malaria vaccine in pregnant people with malaria
This study looks at lab tests for malaria vaccine candidates in pregnant women who currently have malaria. It may help researchers understand which vaccine approaches are safest and most promising for pregnancy.
BamakoAges 15–25 - NCT02321007Recruiting
Study placenta function in healthy and pregnancy complications
This study examines how the placenta works in normal pregnancies and in pregnancies with certain complications. Your answers and pregnancy information may help researchers understand why complications like growth problems or preterm birth happen.
Aurora, ColoradoAges 18–45 - NCT01659749Recruiting
Support and nutrition programs for women with PKU
This study looks at how educational, social support, and nutrition help affect pregnancy outcomes and quality of life in women with PKU. It may help you better manage PKU-related needs before and during pregnancy.
Atlanta, GeorgiaAges 11 years+ - NCT01168271Recruiting
Study malaria risk factors in pregnancy and young children
This study looks at why some people get malaria during pregnancy, and how young children’s bodies respond early in life. It may help researchers understand who is more likely to get malaria and why, which could guide future prevention and care.
BamakoAges 1 day–45 years - NCT05124808Recruiting
Tight blood sugar targets in pregnant women with gestational diabetes
This study compares a tighter blood sugar goal versus a standard goal in pregnant people with gestational diabetes who are also overweight or obese. It may help find whether stricter blood sugar control improves pregnancy outcomes.
Birmingham, AlabamaAges 18–45 - NCT05977686Recruiting
Hemoglobin testing in pregnant adults
This trial studies how hemoglobin (an oxygen-carrying protein in blood) is checked during pregnancy. It may help improve or confirm the best way to monitor blood health in pregnant patients.
Washington D.C., District of ColumbiaAges 18–50 - NCT03830879Recruiting
Pregnancy and child health follow-up study in Shenzhen
This study enrolls pregnant people early in pregnancy and follows their babies’ health through age 7. It may help researchers understand health and development patterns in Shenzhen families and improve future child health care.
Shenzhen, GuangdongAges 15–49 - NCT03398629Recruiting
Study of babies with slow growth or birth defects
This trial looks at how to diagnose and manage pregnancies and babies affected by slow growth before birth, birth defects, or chromosome-related conditions. It may help by improving how doctors confirm problems and plan care for mothers and newborns.
Guangzhou, GuangdongAges Up to 18 years - NCT04047849RecruitingPhase 4
Antibiotics for early water breaking before 23 weeks
