pregnancy Clinical Trials and Research

Also known as: gestation, gravidity, expectant mother, maternity, childbearing, antenatal period · ICD-10: O00-O9A

Pregnancy is the period when a woman carries a developing baby. Clinical trial research aims to improve maternal and fetal health, prevent complications, and understand pregnancy-related conditions. Find a Trial helps patients search for active studies exploring new ways to support healthy pregnancies.

Common questions about pregnancy clinical trials

Who can participate in pregnancy-related clinical trials?

Eligibility criteria vary greatly by study, often depending on the specific condition being researched, gestational stage, and overall health. Researchers use these criteria to ensure patient safety and collect relevant data, as seen on ClinicalTrials.gov. It's important to review each study's requirements.

What are the different phases of clinical trials for pregnancy?

Clinical trials typically progress through phases, from early-stage safety and dosage studies (Phases 1-2) to larger studies evaluating effectiveness and side effects (Phases 3-4). This process helps ensure new interventions are safe and beneficial for pregnant individuals, according to NIH RePORTER data.

Do clinical trials for pregnancy cost money to participate in?

Generally, study-related medical care and interventions in clinical trials are provided at no cost to participants. However, other expenses like travel or lodging are not always covered. Patients should discuss potential costs and reimbursement policies with the study team, as detailed on ClinicalTrials.gov.

What are current research directions in pregnancy clinical trials?

Current research often focuses on preventing preterm birth, managing gestational diabetes and preeclampsia, and understanding fetal development and congenital anomalies. Studies also explore interventions for maternal mental health and postpartum recovery, according to data from ClinicalTrials.gov and NIH RePORTER.

What types of interventions are studied in pregnancy clinical trials?

Interventions can include new medications, dietary changes, exercise programs, medical devices, or behavioral therapies aimed at improving maternal or fetal outcomes. Researchers evaluate their safety and effectiveness throughout different stages of pregnancy, as shown on ClinicalTrials.gov.

Are there specific biomarkers important in pregnancy research?

Yes, researchers often study biomarkers like blood pressure, glucose levels, specific hormones (e.g., hCG, progesterone), and fetal growth indicators. These help monitor pregnancy progression, identify risks, and evaluate intervention effectiveness, according to NIH RePORTER data.

What are common reasons someone might be excluded from a pregnancy clinical trial?

Common exclusion criteria might include pre-existing severe medical conditions, multiple gestations, certain medication use, or a history of specific pregnancy complications. These criteria help ensure participant safety and study focus, as outlined on ClinicalTrials.gov.

What are the potential risks of participating in a pregnancy clinical trial?

Risks vary by study and intervention, but can include side effects from medications, discomfort from procedures, or unforeseen impacts on maternal or fetal health. All potential risks are fully explained in the informed consent process, as required by regulatory bodies.

How to find a pregnancy trial that fits you

  1. Describe your pregnancy situation in detail — stage if applicable, prior treatments, age, and other relevant conditions.
  2. Use the location filter (worldwide, US, US & Canada, Europe) to narrow to trials near you.
  3. Review each trial's eligibility criteria carefully. Save 2–5 candidates with their NCT numbers.
  4. Discuss with your treating clinician before contacting the research site.
