Respiratory Syncytial Virus (RSV) Infection

Researchers are conducting the GENESIS clinical study to map the HLA genomic region in the Greek population and explore its possible links with various underlying diseases. This non-interventional, multicenter study aims to provide a pilot map of genetic variation in HLA that may be useful in medical research and clinical applications related to selected diseases. The study plans to include 12,000 participants over a total duration of 36 months. Each participant will attend one visit at a participating site during which they will provide demographic data, lifestyle information such as smoking and alcohol use, blood pressure measurements, details on diagnosed diseases and treatments, and recent laboratory test results if available. Buccal swab samples will be collected from each participant to extract DNA for HLA genotyping analysis. Selected samples will undergo further whole genome sequencing to investigate associations with autoimmune diseases. Participants will receive a personalized ancestry report after analysis completion. During the study visit, data collection includes demographic and health information, as well as laboratory and clinical test results from the past year. The genetic material from buccal swabs will be stored and processed for genetic analysis. Researchers will measure allele frequency of HLA alleles in the Greek population and assess the prevalence and risk associations of selected HLA-related diseases. The study's total duration is 36 months with results available at the end of this period.

Researchers are conducting a randomized, double-blind, placebo and positive control Phase Ia clinical trial to evaluate the safety, tolerability, and pharmacokinetics of the SIBP-A16 injection in healthy adults aged 18 to 45. The study focuses on understanding how this injection behaves in the body and its safety profile. It involves healthy volunteers without significant medical conditions to ensure reliable results for the Respiratory Syncytial Virus (RSV) research. Participants will be assigned randomly to different groups organized in five queues, with varying doses of SIBP-A16 injection, placebo, or the active comparator Nirsevimab. The injections will be given either intramuscularly or intravenously in single doses across four different dose levels. Each queue undergoes a 14-day safety observation before the next dose level is administered based on safety committee review. During the study, participants will be monitored for adverse events, serious adverse events, and special adverse events of interest from day one up to 361 days after administration. Blood samples will be collected to measure drug levels over time, including peak concentration and time to peak. Various health assessments like physical exams, vital signs, ECGs, chest X-rays, and lab tests will be performed to ensure participant safety and measure outcomes throughout the nearly one-year follow-up.

Respiratory syncytial virus (RSV) is a common virus affecting children, especially young babies, premature infants, and those with heart or lung problems. It is a leading cause of hospitalization for children under 5 years old globally, with many severe cases and deaths occurring in low- and middle-income countries. This research evaluates the safety of an RSV vaccine called ABRYSVO given to pregnant women and how well it protects their infants from severe RSV infections during the first six months of life, particularly in African and lower-middle income countries where data is limited. Pregnant women will receive either the ABRYSVO vaccine or a placebo in a randomized, double-blind trial. The vaccine contains stabilized RSV prefusion F antigens from virus subgroups A and B. The study will enroll pregnant women at the approved gestational age for vaccination, with participants randomly assigned to receive either the vaccine or placebo in equal numbers. The trial will monitor the safety of the vaccine in mothers and infants and measure how well the vaccine prevents severe RSV lower respiratory tract infections in babies up to 180 days old. Participants will attend antenatal clinics and provide informed consent for themselves and their infants. Researchers will follow the women through pregnancy and delivery, recording any preterm births and birth weights. Infants will be monitored for RSV infections confirmed by laboratory tests, and hospitalizations due to RSV will be tracked up to six months of age. Safety assessments include monitoring adverse events in mothers and babies, with follow-up visits and telephone contacts to ensure comprehensive data collection throughout the trial period.

Researchers are evaluating the LIAISON NES FLU A/B, RSV & COVID-19 assay used on the LIAISON NES instrument for detecting and distinguishing influenza A, influenza B, RSV, and SARS-CoV-2 viruses in patients showing symptoms of respiratory tract infections. This test is designed to help in the differential diagnosis of these infections in a professional laboratory setting, but negative results alone should not guide patient management as they do not rule out infection. The study is interventional and involves multiple sites. The trial involves collecting clinical specimens, mainly nasal swabs, from symptomatic patients. These specimens are collected prospectively by healthcare professionals, with up to 40% possibly self-collected under supervision. Nasopharyngeal swabs may also be collected by professionals, especially in children 13 years or younger. The assay uses real-time polymerase chain reaction (RT-PCR) to detect viral RNA directly from dry nasal swabs without the need for nucleic acid extraction. Participants will provide nasal or nasopharyngeal swabs preserved in specific transport media, which are tested on the LIAISON NES instrument within one to two hours of collection. The study measures the diagnostic accuracy and clinical performance of the assay. Specimens are carefully stored and handled to maintain quality. The trial monitors conditions including influenza A, influenza B, RSV, and COVID-19 infections and is expected to complete by May 2025.

Acute respiratory failure is a serious medical emergency that can quickly lead to death without prompt treatment. Researchers are evaluating a new portable device designed to provide Continuous Positive Airway Pressure (CPAP) support outside of hospital settings. This device aims to be easy to use by non-medical individuals and to improve outcomes for patients experiencing respiratory failure. The study will test the device's effectiveness and usability in two groups: healthy elderly adults who will self-apply the device, and hospitalized patients with mild oxygenation impairment. The device is designed to deliver positive end-expiratory pressure (PEEP) between 4 and 7.5 cmH2O, and its performance will be assessed in real-world clinical settings across three hospitals. Participants will be monitored for up to 2 hours during device use, with assessments including how easy the device is to use, duration of proper pressure delivery, battery consumption and duration, and changes in blood oxygen levels (SpO2). The study will collect data to support the device's future use as a first-aid tool for respiratory failure outside hospitals. The total study duration and follow-up details are not specified.

Researchers are evaluating a new multi-component score called the Readiness for EXtubation score (REXs) to predict when ICU patients on invasive mechanical ventilation are ready to be extubated. The process of liberation from mechanical ventilation involves weaning, readiness assessment, and extubation, with success defined as not needing invasive support within 48 hours. This study focuses on developing and analyzing REXs to help clinicians assess extubation readiness more accurately in critically ill patients. The study involves daily screening of ICU patients undergoing weaning from invasive mechanical ventilation. Data collected include clinical parameters such as arterial blood gases, ventilation settings, sedation and agitation scores, heart rate, hemoglobin levels, nutritional status, and cough strength, among others. Clinicians will anonymously enter data into an electronic case report form to develop and evaluate the REXs score. Patients prepared for extubation will have their readiness assessed using this score. Participants will be monitored during their ICU stay, with data collected on extubation success or failure at 24, 48, and 72 hours after extubation. Researchers will also track length of ICU and hospital stays and mortality outcomes. The study uses routine clinical data, with anonymization to protect patient confidentiality. Statistical methods will analyze associations between clinical factors and extubation outcomes to validate the REXs score’s predictive ability. The total study duration extends until the end of 2026.

Researchers are evaluating the safety, tolerability, and how the body processes (pharmacokinetics) single and multiple intravenous doses of a drug called BWC0977 in healthy adult volunteers. This Phase 1 study involves a total of 64 healthy adults aged 18 to 55 years and is designed as a randomized, double-blind, placebo-controlled trial with multiple dose groups. The study focuses on measuring any treatment-emergent adverse events and serious adverse events to understand the drug's safety profile. Participants will be divided into two main groups: single ascending dose (SAD) and multiple ascending dose (MAD) cohorts. In the SAD phase, volunteers receive one intravenous infusion of BWC0977 or placebo over 2 hours at doses of 750 mg or 1500 mg. In the MAD phase, participants receive multiple intravenous infusions of BWC0977 or placebo over 30 minutes to 2 hours daily for 7 to 10 consecutive days. Dose levels will increase sequentially based on safety and tolerability data collected during the study. During the study, participants will undergo various assessments including physical exams, vital signs, ECGs, laboratory tests, and blood sampling at specific times before, during, and after infusions to monitor safety and measure drug levels in the body. Researchers will track adverse events for up to 8 days after single dosing and up to 16 days after multiple dosing. Volunteers must comply with study visits and requirements throughout the trial, which lasts until August 2026.

Researchers are studying the safety and immune response of giving a second dose of the RSVpreF vaccine during later pregnancies, as well as how long protection lasts from a single dose given in an earlier pregnancy. The study involves pregnant participants and their unborn babies, along with nonpregnant participants who received the vaccine before, to understand vaccine effects and immune duration. The trial is a Phase 3 study sponsored by Pfizer focused on respiratory syncytial virus (RSV) infection. The study includes three groups: Cohort 1 consists of pregnant participants who previously received RSVpreF in a Pfizer trial and will get a second dose; Cohort 2 includes pregnant participants who received RSVpreF commercially or in a prior trial, randomized to receive either RSVpreF or a placebo; Cohort 3 involves nonpregnant participants who had RSVpreF during a previous pregnancy and will provide blood samples to assess lasting immunity without receiving new vaccine doses. Infants born to vaccinated pregnant participants are monitored for safety and antibody levels for six months. Participants will attend visits for vaccinations, blood tests, and health monitoring. Pregnant participants are observed for reactions and side effects from the day of vaccination through weeks afterward. Infants are followed from birth up to six months to assess adverse events and antibody presence. The main outcomes include reports of vaccine reactions, adverse events, and the level of RSV antibodies at birth and up to six months. Nonpregnant participants provide blood samples to measure immune response persistence over time. The total study duration extends until February 2028.

Researchers are studying the safety and effectiveness of Deurremidevir Hydrobromide oral suspension in infants and young children aged 1 to 36 months who have respiratory syncytial virus (RSV) infection. This Phase III randomized, double-blind, placebo-controlled trial aims to understand how this investigational drug affects RSV symptoms and disease recovery compared to placebo. The trial is sponsored by Simcere Pharmaceutical Co., Ltd and will enroll about 498 participants. Participants will be randomly assigned in a 2:1 ratio to receive either Deurremidevir Hydrobromide (called SIM0916) or a placebo. The drug dose is adjusted by weight, given at 20 mg per kilogram three times daily for five consecutive days, totaling 15 doses. The study monitors participants through this treatment period, comparing outcomes between the drug and placebo groups. During the study, infants and children will be regularly assessed for RSV-related clinical signs and symptoms, including wheezing and cough, using scores like the Wang Bronchiolitis Score. Researchers will track recovery times and the need for intensive care or respiratory support. Safety and symptom resolution will be followed up to day 26 after the first dose. The total participation duration covers screening, treatment, and follow-up assessments to evaluate the drug's impact and monitor safety.

Researchers are evaluating the combination of Adebrelimab with carboplatin or cisplatin plus etoposide chemotherapy and concurrent radiotherapy as a first treatment for patients with extensive-stage oligometastatic small cell lung cancer. This Phase II open-label study aims to assess the safety and effectiveness of this regimen in this patient group. The trial is led by Nanfang Hospital, Southern Medical University and focuses on patients with limited metastatic lesions and organs affected. Participants will first receive Adebrelimab intravenously along with carboplatin or cisplatin and etoposide for two cycles during the induction phase. Next, participants undergo concurrent chemoradiotherapy, including thoracic radiation and stereotactic body radiation therapy (SBRT) to metastases, combined with one to two cycles of chemotherapy. Following this, they will receive one to two additional cycles of Adebrelimab combined with chemotherapy, and then continue on Adebrelimab alone as maintenance therapy until disease progression, unacceptable side effects, or withdrawal from the study. During the study, participants will be closely monitored through clinical assessments, imaging, and laboratory tests to track progression-free survival and other measures such as overall survival and response rates, with follow-up lasting up to approximately 30 months. Safety will be monitored by recording adverse events throughout the treatment and maintenance phases. The total participation time includes induction, concurrent chemoradiotherapy, maintenance, and follow-up periods to fully evaluate treatment outcomes and tolerability.
