Findings from a Johns Hopkins Medication analysis research revealed at the moment in JAMA Community Open present sturdy proof that people who find themselves pregnant and have been contaminated with SARS-CoV-2 (the virus that causes COVID-19) can safely take the antiviral drug Paxlovid to scale back the potential for extreme illness.
Primarily based on our outcomes, we really feel that the profit to each the mom and the growing fetus of stopping extreme COVID outweighs any potential dangers from Paxlovid remedy.”

Paxlovid is an investigational agent (nonetheless underneath research) getting used as a therapy for sufferers with mild-to-moderate COVID-19. It consists of two medicines: nirmatrelvir, an antiviral agent that inhibits a key enzyme that SARS-CoV-2 wants to breed infectious progeny, and ritronavir, a drug that enhances the motion of nirmatrelvir by conserving it longer within the physique. In December 2021, the US Meals and Drug Administration licensed the emergency use of Paxlovid for adults and youngsters age 12 years and older contaminated with SARS-CoV-2 and at excessive threat for development to extreme COVID, together with hospitalization and loss of life.
“The scientific trials that enabled Paxlovid to obtain its emergency use authorization confirmed that members have been 89% much less prone to develop extreme sickness and loss of life; nevertheless, individuals who have been pregnant weren’t among the many members, and being pregnant is now recognized to be a situation inserting sufferers vulnerable to extreme illness,” says co-study senior writer Irina Burd, MD, Ph.D., previously professor of gynecology and obstetrics on the Johns Hopkins College Faculty of Medication and now chair of the Division of Obstetrics, Gynecology, and Reproductive Sciences on the College of Maryland Faculty of Medication.
Of their research, the researchers chosen members from 3,442 individuals who have been pregnant, recognized with mild-to-moderate COVID-19 and seen at facilities throughout the Johns Hopkins Well being Techniques between March 15, 2020, and Aug. 20, 2022.
From this inhabitants, 47 individuals who met the research standards have been prescribed Paxlovid and monitored for outcomes and any issues. The median age of this group was 34, 17% have been Black, 11% have been Hispanic and the median gestational age (stage of being pregnant) was 28 weeks. Nearly all of members had acquired no less than their preliminary COVID vaccinations and began Paxlovid remedy inside in the future of symptom onset.
Ninety-six % (45 out of 47) of the members accomplished the course of remedy, tolerating it properly. Of those, 25 infants delivered following the therapy. Twelve of the deliveries have been completed by cesarean part, and of these, 9 have been scheduled and never associated to therapy. Two members have been hospitalized for pre-existing situations and never extreme COVID.
Total, the incidence of maternal and fetal issues from Paxlovid have been inside anticipated limits.
“There are some limitations to our analysis, together with using knowledge from a single well being system and the small inhabitants studied with gentle COVID,” says Garneau. “However we imagine that our research is the biggest so far Paxlovid’s security and efficacy in individuals who have been pregnant on the time of remedy, and subsequently, signifies that the therapy needs to be an choice for these sufferers.”
Various medical organizations agree, together with the Society for Maternal-Fetal Medication, which states it “helps using Paxlovid for therapy of pregnant sufferers with COVID-19 who meet scientific {qualifications},” and the American School of Obstetricians and Gynecologists, which lists being pregnant “among the many situations that put people at excessive threat for scientific development [to severe COVID]. This makes pregnant sufferers, together with these with being pregnant as their solely threat issue, eligible to obtain outpatient oral SARS-CoV-2 protease inhibitor remedy [Paxlovid].”
“Whereas extra research of Paxlovid is required to substantiate our findings of its security and efficacy throughout being pregnant, we really feel that even at the moment, the remedy needs to be strongly thought of for pregnant sufferers who’re unvaccinated or in danger for development to extreme COVID illness or not prone to have drug-drug interactions,” says co-study senior writer Kelly Gebo, MD, MPH, professor of medication on the Johns Hopkins College Faculty of Medication.
Together with Garneau, Burd and Gebo, the members of the research group embody Kimberly Jones-Beatty, Sabra Klein, Heba Mostafa and Michelle Ufua, all from Johns Hopkins Medication.
The research was made potential by the Johns Hopkins Institute for Medical and Translational Analysis, which is funded partially by grant UL1 TR003098 from the Nationwide Institutes of Well being’s Nationwide Middle for Advancing Translational Science, and the NIH Roadmap for Medical Analysis.
