New registry tracks COVID drug safety for pregnant women and their babies
NCT ID NCT05013632
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This registry is following 2,000 pregnant women who took antiviral drugs or monoclonal antibodies for COVID-19. Researchers will compare their pregnancy and baby outcomes to those who did not receive these treatments. The goal is to better understand the safety of these medications during pregnancy.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- antiviral drugs (remdesivir, molnupiravir) and monoclonal antibodies (casirivimab/imdevimab, sotrovimab)
- What this could lead to
- If successful, this registry could provide crucial safety data on COVID-19 treatments during pregnancy, helping doctors make informed decisions.
- What could go wrong
- This is an observational registry, not a controlled trial, so it cannot prove cause and effect. Results may take years and depend on accurate reporting.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
The exposed study population consists of pregnant or recently pregnant women 18 years of age and older treated with at least one dose of a monoclonal antibody or antiviral drug indicated for COVID-19 from first day of the LMP to end of pregnancy. For monoclonal antibodies, the exposure period also includes 90 days prior to the first day of the LMP. The reference groups include pregnant women not exposed to monoclonal antibodies or antiviral drugs and treated with another therapy for mild, moderate, or severe COVID-19 (active comparator) and women who experienced COVID-19 during pregnancy and were hospitalized but were not treated with a medication specifically indicated for mild, moderate, or severe COVID-19 (unexposed comparator), matched by calendar time, country of residence, gestational timing at the time of COVID-19 infection (± 2 weeks), and severity of COVID-19.
