| NCT06955728 ↗ | A Clinical Trial on Safety in Pregnant Women and How Well the Infant is Protected Against RSV-associated Lower Respiratory Tract Infection When the Pregnant Woman Receives the Approved RSV Vaccine Compared to a Placebo. | NOT_YET_RECRUITING | Bill and Melinda Gates Foundation | PHASE4 | 2025-05-01 | Respiratory syncytial virus (RSV) is a virus that often affects children during childhood. Even though most cases of RSV are mild, it can cause serious disease and even death - especially in very young babies, babies born too early and those born with heart and lung problems. It is the most common cause for children under 5 years old to be hospitalised. In 2019, there were about 33 million RSV-infections in the lower respiratory tract (in the lungs and below the voice box) of which 3,6 million people were hospitalised and 26,300 passed away in hospital due to RSV. Almost half (50%) of deaths that are caused by RSV, happen in children younger than 6 months old and the majority (more than 95%) of these deaths happen to infants and children in low- and middle-income countries. A way that can help protect babies from becoming infected is through giving vaccines against the germ (RSV) that is targeted for prevention. There are currently no registered vaccines that can be given directly to babies however there is a lot of information available that shows that a vaccine can be safely giving to a mother while she is still pregnant. The mother then produces antibodies (protection cells) that is transferred to the baby before the baby is born, and the baby is protected from getting sick during the first few months of life. One of the vaccines that has been developed (ABRYSVO) has been used in many clinical trials in pregnant moms (and older people) to test if it is safe and will protect young babies and much older people who are all at the highest risk for a severe RSV disease. The vaccine was given to more than 4,000 pregnant women. The results from the study and previous studies showed that the vaccine was safe and the babies had a lower chance of getting severe RSV disease and going to hospital. It showed that the vaccine prevented severe RSV infection in around 80% of babies younger than 90 days, and 70% of babies younger than 6 months. Therefore, the vaccine has been licensed in a few countries around the world (including the United States of America and other high-income countries) which means that pregnant women can receive this vaccine during their pregnancy if they wish to (without being on a clinical trial). It has also been licensed in South Africa but is not yet available in the country for pregnant women to receive. The licensure is also underway in other African countries. However, the results of the previous studies of this vaccine also showed that a slightly higher number of premature babies were born to women who received the vaccine compared to women who did not receive the vaccine. The information received from these studies was however not enough to decide if the earlier births were related to the vaccine or not, and more information is needed - which is one of the main reasons for this study. Importantly, all of the babies who were born earlier were only born a few weeks earlier than expected (around 35 weeks of pregnancy), and all the babies were well and survived. The previous studies on this vaccine happened during the COVID-19 pandemic at which time people were wearing masks and contacting other people less therefore not spreading RSV around as we would normally expect. By doing this study, it will assist the investigators to determine if the vaccine is really as good as it is perceived to be for preventing serious RSV illness in the babies. This RSV vaccine is a very important medical intervention, and it is as important that the effect that this vaccine will have on pregnant women and on the infants born to mothers who receive the vaccine can be measured. It is especially important in African and lower-middle income countries as the vaccine was not tested as much in people living in Africa compared to others. Therefore, the main reason for doing this trial is to see how much value the vaccine can bring to these countries in terms of protecting young babies and infants where many may get a severe infection and be hospitalised. It will also measure if the vaccine does increase the chances of a baby being born earlier than expected. It will only be carried out in the countries after the vaccine has been approved for use by pregnant women (at the right time) as part of their pregnancy care. |

| NCT07041190 ↗ | Pregnancy and Infant PrEparedness pLatform IN Europe, RSV-International Adaptive Platform Trial to Evaluate Two Approved Prevention Options to Prevent Respiratory Syncytial Virus in Infants: Maternal Vaccine to Women in Pregnancy and Monoclonal | NOT_YET_RECRUITING | PENTA Foundation | PHASE3 | 2025-09-01 | RSV (which stands for Respiratory Syncytial Virus) is an infection that causes cold-like symptoms and is most common during winter months. Most people with RSV infection get better by themselves but babies and younger children can become very poorly. About 1 in 15 infants with confirmed RSV within the first 12 months of life will be hospitalised, and a very small proportion will be seriously ill and may die. Currently there are two different prevention options that can be used to prevent RSV infection in babies. One is a vaccine given to the mother during pregnancy, and the other is a monoclonal antibody given by injection to the baby. Although both prevention options work well on their own and are safe, neither provides 100% protection to the infant. It is not known whether giving both medicines, one to the mother in pregnancy and one to the infant, would provide better protection than giving only one medicine - this is what the PIPELINE-RSV study will look at. PIPELINE-RSV-International will recruit about 1500 pregnant women from across Europe in UK, Switzerland, the Netherlands and Belgium. A parallel trial, PIPELINE-RSV-France, running in France will recruit about 1000 pregnant women in France; the protocols will align on key aspects and the data will be analysed together. The study will include three study groups with different prevention options used in each: (1) a vaccine given to the mother in pregnancy, (2) an injection given to the baby at the beginning of RSV season, or (3) both a vaccine given to the mother in pregnancy and an injection given to the baby at around 4 months of age. Each mother-baby pair will be randomly allocated to group by a computer. The numbers of babies in each of these groups who acquire RSV will be compared. In some countries only two of the three study groups may be available. Pregnant women and their babies will be followed until the baby reaches 12 months of age. Information will be collected about medically-important side effects either the mother or the baby had from their medicine(s) and any symptoms of RSV the baby had. Visits with the mother and baby will occur at birth, and 4 and 12 months later; these will ideally be in-person at birth and at 12 months. The mother will complete questionnaires via a Web-based platform to report any non-routine in-person visits, once in pregnancy and after the baby is born twice a month or monthly (more often in the winter), to also report baby's symptoms, to report their trial experience when the baby is 4 and 12 months' old, and to provide their views on vaccination at birth, and when the baby is 4 and 12 months' old. If the baby develops symptoms that might be RSV, their mother or another caregiver will be asked to take a sample using a swab from the baby's nose or mouth, and to send it by post for testing to find out if the baby has RSV. As well as the main research study, there are also some substudies. A questionnaire will be given to women who consent to take part, to find out their motivations for joining the study and how they prefer to receive information about taking part in studies. A small number of women will be asked to take part in a study to look at how mothers' and babies' immune systems respond to the two different study prevention options , and to investigate different ways of collecting samples from their babies. In addition, researchers will use data from the study to see whether giving both medicines is cost-effective compared with giving just one medicine. The study might be adapted in the future to look at other medicines for preventing RSV infection, when they become available. |
