NCT07249320
To generate critical evidence to support vaccine policy and implementation, Pfizer will collaborate with Kaiser Permanente Northern California (KPNC) to study the vaccine effectiveness (VE) of ABRYSVO vaccination during pregnancy in a real-world population. The overall research question of this study is: what is the effectiveness of ABRYSVO vaccination during pregnancy against medically-attended (MA) RSV-associated and all-cause infant outcomes in a large, diverse, real-world population? This study will use a retrospective cohort design and will be conducted within an integrated delivery health care organization using electronic medical record (EMR) data collected during routine standard of care clinical encounters. Study outcomes among infants born to ABRYSVO-vaccinated mothers (exposed group) will be compared with those among infants born to ABRYSVO-unvaccinated mothers (comparison group) initially from birth through 6 months of age, with later assessments from birth through 12 months of age and through 24 months of age as the infants reach these age thresholds and their data become available. There are two categories of outcomes of interest in this study: RSV-specific infant outcomes and non-specific all-cause infant outcomes, assessed within several follow-up windows (birth through 6 months of age, birth through 12 months of age, and/or birth through 24 months of age, depending on the outcome). Identification of RSV-specific outcomes will be based on the first positive laboratory-confirmed PCR test from a respiratory specimen during a healthcare encounter in a KPNC healthcare setting, occurring during the relevant follow-up window. RSV-positive test results will be combined with International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) diagnostic codes to define the RSV-specific outcomes. RSV-specific outcomes will include: PCR-confirmed RSV, PCR-confirmed RSV hospitalization, PCR-confirmed RSV LRTD, and PCR-confirmed RSV LRTD hospitalization. Non-specific all-cause infant outcomes will include: all-cause LRTD, all-cause LRTD hospitalization, acute otitis media, and new antibiotic prescription (for any diagnosis). Identification of these outcomes will be based on ICD-10-CM diagnostic codes documented in infant EMRs during a healthcare encounter in a KPNC healthcare setting, occurring during the relevant follow-up window.

NCT05045612
Antimicrobial resistance is one of the most urgent health threats of our time, and Norwegian hospitals were required to reduce the use of broad-spectrum antibiotics with 30% by the end of 2020. In the current proposal, the investigators aim to assess the efficacy and safety of early discontinuation of antibiotic therapy in adult patients infected with respiratory viruses. A general recommendation to treat all instances of community acquired pneumonia (CAP) patients with antibiotics leads to significant antibiotic overtreatment. In 2008, the US Food and Drug Administration approved the first multiplex polymerase chain reaction assay for the detection of multiple respiratory virus nucleic acids simultaneously. The wide availability of such nucleic acid amplification tests (NAAT) for rapid viral detection together with chest radiographs has the potential to define patients who can be managed without antibiotics. Akershus University Hospital is one of the largest hospitals in Norway, with a catchment area of more than 550,000 people. In 2012 to 2013, the majority of patients admitted to Akershus University Hospital with suspected CAP and a positive viral NAAT were treated with antibiotics, a prescription pattern representing antibiotic overtreatment. The investigators accordingly hypothesize that discontinuation of antibiotic therapy in patients with moderately severe disease and airway sample positive for respiratory viruses is safe and non-inferior to continuation of antibiotic therapy.
NCT05842967
The purpose of this study is to learn about the safety and immunogenicity of a study vaccine (called RSVpreF) in several adult groups. Respiratory Syncytial Virus (RSV) is a common type of virus (germ) that can cause severe illness, where medical help is needed. RSV can lead to airway diseases in all ages. Vaccines help your body make antibodies which help fight against diseases. This is called an immune response. This study will measure how much antibody participants make after receiving RSVpreF (immunogenicity). The study consists of 2 groups (Substudy A and Substudy B). Substudy A is seeking approximately 675 participants who are: * Between 18 and 60 years of age. * Considered having a high likelihood of severe RSV disease due to certain long-term medical conditions. Such medical conditions do not include immunocompromising conditions. Participants will need to come to the study clinic at least 2 times. At the first clinic visit, participants will receive 1 shot of RSVpreF or placebo in the arm by chance. A placebo looks like the study vaccine but contains no active ingredients. At each clinic visit, a blood sample will be taken. A third (final) visit can be either completed in clinic or via telephone contact. This study is about 6 months long for each participant. Substudy B is seeking approximately 200 participants who are: * At least 18 years of age. About half of the participants will be at least 60 years of age. * Considered having a weakened immune system (immunocompromised). Participants will need to come to the study clinic at least 3 times. All participants will receive a shot of RSVpreF at the first study clinic visit. The second study clinic visit will be 1 month later. All participants will receive a second shot of the study vaccine at this second study clinic visit. Blood samples will be taken at the 3 study clinic visits. A fourth (final) visit can be either completed in clinic or via telephone contact. This study is about 7 months long for each participant.

NCT06873633
THAI-CARES RSV Study is a Phase II, open-label, multicenter, randomized controlled trial with a two-arm, parallel-group design. The study aims to assess the safety, efficacy, and acceptability of a five-day course of Remdesivir (VEKLURY®) in children under two years of age who are hospitalized with confirmed respiratory syncytial virus (RSV) infection, as determined by either a rapid antigen test or RT-PCR. The primary objectives include evaluating the treatment's safety profile, its ability to significantly reduce RSV replication, and its overall acceptance in this patient population.
NCT06998251
The NoseSpn-Elderly study aims at characterizing the immune response in the upper respiratory tract in adults aged 60 and over diagnosed with a pneumonia due to a Streptococcus pneumoniae (Spn) infection. The immune response during the acute phase of the infection and after recovery will be compared to the immune response of asymptomatic Spn carriers as well as to the immune response of patients diagnosed with a viral respiratory infection (flu or respiratory syncytial virus (RSV)). The primary objective of this observational study is to quantify the inflammatory response in the nasal cavity and to correlate it with bacterial/viral load and with clinical parameters. The study also aims to compare the inflammatory response measured in the nose to that measured in the blood. Participants will have two study visits including a blood draw, several nasal samplings (nasal lining fluid and nasal cells) and a saliva sampling, one within 72 hours of their hospital admission and another one month later. Nasal lining fluid and saliva will be obtained every two or three days until discharge from the hospital or resolution of symptoms. During those visits, questions regarding symptoms will be asked.
NCT04896853
To investigate the safety and tolerance of a single infusion of ProTrans® in subjects with "severe" respiratory complications associated with pneumonia caused by COVID-19, Influenza A, Metapneumovirus or RSV infection.
NCT04225897
The purpose of this clinical trial is to learn about the safety and effects of the study medicine (sisunatovir). Sisunatovir is developed as potential treatment of Respiratory Syncytial Virus (RSV) infections. This study will assess sisunatovir as compared to placebo in infants aged 1 month to 36 months who are hospitalized with RSV lower respiratory tract infection (LRTI). A placebo looks like the study medicine but does not contain any active medicine in it. This study will be conducted in 3 parts: In Part A participants aged 6 months to 3 years will be given a single dose of 2.5 mg/kg of sisunatovir in Cohort 1. In Cohort 2, participants age 1 month to 6 months will receive a single dose of 2 mg/kg of sisunatovir only after the completion of Cohort 1. 12-24 participants will be enrolled in Part A In Part B participants age 1 month to 36 months will receive sisunatovir or placebo dosed every 12 hours for 5 days. Doses for part B will be determined after the completion of Part A. 24-40 participants will be enrolled in Part B. The dose regimen for Part C will be determined after the completion of Part B. Approximately 120 participants age 1 month to 36 months will receive either sisunatovir or placebo. To participate in this study participants must meet the following criteria: 1. Age 1 month to 36 months 2. Weight ≥ 3.5 kg 3. Diagnosis of LRTI 4. Diagnosis of RSV 5. Hospitalization due to RSV LRTI
NCT06067191
The purpose of the study is to learn about the safety, pharmacokinetics and antiviral activity of the study medicine (RV299) for the potential treatment of respiratory syncytial virus (RSV). RSV is a highly contagious virus that can lead to serious lung infections in patients with reduced ability to fight infection. Most vulnerable populations include babies, the elderly and patients that have received a bone marrow transplant.
