14 Clinical Trials for Various Conditions
Vaccinating pregnant women affords a unique opportunity to protect both mother and child against influenza and pertussis, yet uptake of maternal immunizations remain far below national target goals. A significant barrier to vaccine uptake is the lack of evidence to guide provider communication with patients who have concerns about vaccines. This novel study will adapt motivational interviewing to the ob-gyn setting to provide information about how to improve provider communication and increase vaccine uptake among pregnant women. The investigators propose a pragmatic practice-based study in 5 ob-gyn practices in Colorado to develop the MI for maternal immunizations (MI4MI) intervention and assess fidelity, acceptability, and feasibility among patients and providers. Aim 1 will use an iterative process building upon existing knowledge of patient concerns about maternal immunizations and our prior experience training providers in Motivational Interviewing (MI) for childhood immunizations to develop the MI4MI training. During development, the study team will conduct focus groups to elicit provider input during. The MI4MI intervention will include a video-module, 2 asynchronous online trainings, provider reference sheets, and practice study champions. Aim 2 will include intervention implementation and assessment of intervention fidelity, acceptability, and feasibility. In Aim 2a, will conduct pre- and post-intervention chart reviews among participating practices to evaluate the impact of MI4MI on influenza and Tdap vaccine uptake among pregnant patients.
The purpose of this study is to determine the efficacy of maternal immunization during the third trimester of pregnancy with the RSV F vaccine against medically-significant RSV lower respiratory tract infection (LRTI), as defined by hypoxemia or tachypnea at rest, through the first 90, 120, 150, and 180 days of life in infants.
The purpose of this study is to evaluate the safety and immunogenicity of an RSV-F protein nanoparticle vaccine, with aluminum, in healthy third-trimester pregnant women and to assess the impact of maternal immunization on infant safety through one year of life.
Study objectives are to compare * influenza antibody levels in infant sera and maternal colostrum or breast milk at delivery, 2, and 6 months women who receive influenza immunization in early pregnancy, late pregnancy, or no influenza immunization during pregnancy and their infants Study hypotheses are that infants born to pregnant women who receive influenza immunization in late pregnancy will have * higher levels and a longer serum influenza antibody duration in sera (hemagglutination inhibition (HAI) titers) and colostrum/breast milk (influenza-specific IgA and IgG by enzyme-linked immunosorbent assay (ELISA) than infants of women immunized in early pregnancy or not immunized
The main objective of this study is to evaluate whether immunization with 9-valent pneumococcal conjugate vaccine (PNCRM9) during the third trimester of pregnancy interferes with active antibody production in offspring immunized with PNCRM7 (Prevnar) in the first six months of life.
Results will be submitted, however please note that data are not yet available for all serology outcome measures. This will be a Phase 2/3, randomized, placebo-controlled, observer-blind study evaluating the safety, tolerability, and immunogenicity of 30 µg of BNT162b2 or placebo administered in 2 doses, 21 days apart, in approximately 350 healthy pregnant women 18 years of age or older vaccinated at 24 to 34 weeks' gestation. Participants will be randomized 1:1 to receive BNT162b2 or placebo (saline).
This study aims to check how safe and well-tolerated a second dose of RSVpreF is when given during later pregnancies, and to see how long the immunity lasts from a single dose given during a previous pregnancy by examining the blood of nonpregnant participants who had the vaccine before.
The purpose of this study is to assess the safety, reactogenicity and immunogenicity of the investigational GSK RSV vaccine in pregnant women aged 18 to 40 years and infants born to the vaccinated women
Respiratory Syncytial Virus (RSV) is the leading cause of lower respiratory tract infections (LRTIs) in infants and young children. It is also a leading cause of mortality in children \<5 years of age worldwide. Until recently, no Food and Drug Administration (FDA)-approved vaccines were available to prevent RSV infection. The only prophylactic product for RSV prevention recommended for infants was the monoclonal antibody palivizumab, but administration was limited to those with extreme prematurity, chronic lung disease, or hemodynamically significant congenital heart disease. However, in 2023, the FDA approved two products designed to prevent RSV lower respiratory tract disease (LRTD) in all infants: an active RSV vaccine based on the prefusion F protein (RSVpreF, ABRYSVO, Pfizer) administered during pregnancy, and a passive, long-acting monoclonal antibody (nirsevimab-alip \[henceforth referred to as nirsevimab\], BEYFORTUS, AstraZeneca) administered to infants at birth or at the start of their first RSV season. Both products were evaluated in Phase 3 pivotal clinical trials and have high efficacy in preventing LRTD caused by RSV in infants. Although there is no established correlate of protection against RSV, antibodies have been associated with protection across multiple studies. The clinical development plan for the products did not include comprehensive evaluations of the magnitude and durability of the immune response, nor were the two products tested in a single trial. This study is a prospective, randomized, open-label Phase 4 study with the primary objective of evaluating the magnitude and durability of RSV-specific neutralizing antibodies in infants through 12 months of life following either maternal RSV vaccination, infant nirsevimab administration, or both products combined.
COVID-19 infection during pregnancy is associated with increased risk of pre-eclampsia, preterm birth and stillbirth. Pregnant people with COVID-19 have a higher rate of ICU admission and intubation than those who are not pregnant. COVID-19 vaccine is recommended before pregnancy and during pregnancy to decrease these risks. Despite the benefits of COVID-19 vaccination, only 71% of pregnant women were vaccinated for COVID-19 as of June 2022 (most prior to pregnancy), with a much lower rate of 58% among non-Hispanic Black women. An effective intervention is needed to improve COVID vaccination rates for pregnant people overall. In this study, the investigators will perform a randomized controlled trial aimed at practice change in obstetricians' offices, with an overall goal of increasing maternal COVID-19 vaccination rates.
This is an observational, non-interventional, prospective cohort study designed to collect clinical information and specimens to evaluate the immune responses from pregnant individuals and postpartum individuals and their infants following maternal receipt of licensed or Emergency Use Authorization (EUA) severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines.
This is a prospective, observational study. During the study, pregnant women will be followed post COVID-19 vaccination. Injection-site (local) and systemic reaction data will be assessed on vaccination day and during the 7 days following the second vaccination using either identical web-based or paper diaries, depending on study participant preference. Maternal serum samples will be collected for antibody titers relevant to COVID-19 at time points that include: prior to vaccination, \~29 days post second vaccination, and at delivery. At Duke University, maternal and infant cord blood will be collected at delivery and analyzed for the same antibody titers. At other clinical sites, these delivery samples will only be collected if feasible. Pregnant women will be followed through 90 days postpartum. with comprehensive obstetric and neonatal outcomes obtained from medical record review.
To evaluate the effect of anti-HIV immune serum globulin (HIVIG) versus immune globulin (IVIG) administered during pregnancy and to the newborn, in combination with zidovudine (AZT) administered intrapartum and to the newborn, on incidence of HIV infection in infants born to HIV-infected women who received AZT during pregnancy for medical indications. Vertical transmission of HIV from mother to child may occur before, during, or after parturition (via breast-feeding). It is believed that therapy administered both during pregnancy and intrapartum may help prevent vertical transmission. Additionally, adjunctive short-term antiretroviral therapy for the newborn, following the intensive viral exposure presumed to occur at birth, may be necessary.
The purpose of this study is to test a behavioral intervention to minimize sleep disruption and fatigue in new mothers after the birth of their first infant. This study also tests whether an acetaminophen intervention at the time of an infant's 2-month immunization series improves infant and maternal sleep.
