Filter by:The main purposes of Part A of this study are to evaluate the safety, tolerability, and immunogenicity of mRNA-1345 coadministered with a seasonal influenza vaccine (Afluria® Quadrivalent); to evaluate the impact of coadministered influenza vaccine on the immune response to RSV-A; and to evaluate the impact of coadministered RSV vaccine on the immune response to influenza. The main purposes of Part B of this study are to evaluate the safety, tolerability, and immunogenicity of mRNA-1345 coadministered with mRNA-1273.214; to evaluate the effect of coadministered mRNA-1273.214 on the immune response to RSV-A; and to evaluate the effect of coadministered RSV vaccine on the immune response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The main purposes of Part C (single arm, open-label) of this study are to evaluate the safety and tolerability of a booster dose (BD) of mRNA-1345 administered at 1 Year following a primary dose; to evaluate the immune response to RSV-A of a BD of mRNA 1345 administered at 1 Year following a primary dose; and to evaluate the immune response to RSV-B of a BD of mRNA-1345 administered at 1 Year following a primary dose.
The purpose of this study is to assess the safety and immunogenicity of RSVpreF when coadministered with SIIV compared to sequential administration of the vaccines when given 1 month apart (SIIV followed by RSVpreF). Additionally, the study will contribute data supporting the development of RSVpreF as a prophylactic vaccine against RSV disease in infants through maternal immunization and in older adults through active vaccination.
The main purpose of Part A of this study is to evaluate the safety and tolerability of mRNA-1345 vaccine and to demonstrate the efficacy of a single dose of mRNA-1345 vaccine in the prevention of a first episode of RSV-associated lower respiratory tract disease (RSV-LRTD) as compared with placebo from 14 days postinjection through 12 months. The main purpose of Part B of this study is to evaluate the safety, tolerability and immunogenicity of a booster dose (BD) of mRNA-1345 administered 24 months after the primary dose.
The purpose of this study is to evaluate the efficacy of rilematovir compared to placebo with respect to the time to resolution of respiratory syncytial virus (RSV) lower respiratory tract disease (LRTD) symptoms.
The primary objectives of this study are to evaluate the tolerability and reactogenicity of a single injection of up to 5 dose levels of mRNA-1345 in younger adults, women of child-bearing potential, and older adults including Japanese older adults; of 3 injections of the middle dose level of mRNA-1345 given 56 days apart in younger adults; of a booster injection of mRNA-1345 given approximately 12 months after the primary injection in older adults; and of 3 injections of 1 of 2 dose levels of mRNA-1345 given 56 days apart in children who are RSV-seropositive.
The purpose of this pre-approval access program is to provide treatment to immunocompromised participants with serious/life-threatening diseases or conditions (Respiratory Syncytial Virus [RSV] infection) and to collect the safety data to understand the safety profile of JNJ-53718678.
This was a randomized, double-blind, placebo-controlled, multicentre, phase 2 study to evaluate the efficacy, safety and tolerability of orally administered EDP-938 in adults with RSV infection.
The purpose of this study is to assess the safety and reactogenicity of an intramuscular regimen of 3 doses of 2.5*10^10 viral particles (vp) of adenovirus serotype 26 based respiratory syncytial virus pre-fusion protein (Ad26.RSV.preF) vaccine in RSV-seronegative toddlers aged 12 to 24 months.
The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics, and incidence of anti-drug antibodies (ADAs) of single ascending doses of clesrovimab in healthy pre-term (born at 29 to 35 weeks gestational age) and full-term (born at >35 weeks gestational age) infants. Participants will be randomized into 1 of 4 dose escalation panels (Panels A to D); an additional panel (Panel E) of full-term infants will receive the same dose as Panel D. Key safety and tolerability variables will be reviewed after each dose panel prior to administering the next-highest dose.
Background: Respiratory Syncytial Virus (RSV) is a virus that infects the lungs and breathing passages. Healthy adults who are infected generally have mild cold symptoms for a week or two. But it can also be serious, especially for infants and older adults. It can be spread by direct or indirect contact with respiratory secretions. Researchers want to study a new vaccine to prevent RSV. Objective: To see if a vaccine for RSV is safe and if it causes side effects. Eligibility: Healthy adults 18-50 years old Design: Volunteers were screened in a separate screening protocol. Subjects had 13 visits over 1 year. Some subjects received just vaccine. Some received vaccine mixed with alum adjuvant. All subjects received their dose by injection in the upper arm. They received up to two doses, one at the beginning of the study and another 12 weeks later. Subjects were monitored for 1 hour after injection and called to check on their safety 1 day after. Subjects recorded their temperature and side effects for 7 days after each vaccination. Subjects were provided with a thermometer to measure their temperature and a ruler to measure any changes if these occurred on their skin at the injection site. At all visits, subjects were checked for health changes or problems. They may have had blood drawn. At some visits, subjects had samples collected from their nose and mouth.
