Comparing the Incidence of Preeclampsia Between Pregnant Women Receiving Tdap Vaccinations at Week 28 or at Week 36
June 11, 2020 updated by: Institute of Arthritis Research
A Prospective Randomized Clinical Research Trial Comparing the Incidence of Preeclampsia Between Pregnant Women Receiving Tdap Vaccinations at Week 28 and Those Receiving Tdap Vaccinations at Week 36
Preeclampsia is a significant medical condition occurring in 3-8% of pregnancies and impacts deleteriously both maternal and fetal health.
An important discovery has been made by Dr Craig D Scoville showing that early Tdap vaccinations in pregnancy can reduce the incidence of preeclampsia by more than 50%.
A prospective clinical research trial is proposed and urgently needed to validate this finding and thereby make a significant contribution in reducing the incidence of this common and severe complication of pregnancy.

Detailed Description
A double blinded randomized prospective clinical research study is proposed to validate the hypothesis that Tdap vaccinations at week 28 in pregnancy can reduce the incidence of preeclampsia by more than 50%.
This project will recruit 1600 pregnant women with appropriate informed consent in the first trimester of pregnancy, obtain detailed obstetric and health history, and then randomize these subjects so 800 women receive Tdap at week 28, and 800 women receive Tdap at week 36, and all women will be followed during their pregnancies using standard of care with special attention to preeclampsia and fetal outcomes.
Blood samples will be obtained at weeks 12, 20, and 36 in order to test the anti-tetanus toxoid antibody levels, anti-diptheria antibody levels, anti-pertussis antibody levels, and also maternal cytokines (IL-2, IL-4, IL-6, IL-10, TNFa, IL-17, and IFNg), and placental biomarkers (sFlt-1, sEng, and PIGF) for preeclampsia on those patients who develop preeclampsia and compare to those who didn't and thereby better understand the biomarkers of preeclampsia and devise a better formula for positive prediction for preeclampsia.
To make this change in clinical practice and save lives, this study is asking for funding from NICHD PA-18-480.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Tdap vaccinations at gestational week 28
Pregnant women entering into this clinical research study and signing informed consent at week 12 will be randomized to either receive Tdap vaccination at week 28 or week 36.
Subjects receiving Tdap vaccination at week 28 will receive a placebo injection at week 36.
Subject will be followed with routine standard of care throughout their pregnancy and have routine clinic visits from which study visits will include weeks 12, 20, 28, 36, and 2 weeks postpartum.
Data will be collected at each of these visits with special attention to the development of preeclampsia and fetal health
|
Tdap vaccinations are routinely given during pregnancy between weeks 27 and 36 per guidelines of American College Obstetrics and Gynecology (ACOG) -- but this study uniquely is trying to establish that the earlier Tdap vaccinations reduce preeclampsia by more than 50%
|
Active Comparator: Tdap vaccinations at gestational week 36
Pregnant women entering into this clinical research study and signing informed consent at week 12 will be randomized to either receive Tdap vaccination at week 28 or week 36.
Subjects receiving Tdap vaccination at week 36 will receive a placebo injection at week 28.
Subjects will be followed with routine standard of care throughout their pregnancy and have routine clinic visits from which study visits will include weeks 12, 20, 28, 36, and 2 weeks postpartum.

Incidence of preeclampsia in each arm of the study with regards to timing of Tdap vaccination
Time Frame: Through duration of pregnancy approximately 10 months
