A Phase 1/2A, Randomized, Double-Blind Study to Evaluate the Safety, Tolerability, and Pharmacokinetics of HT31-1 (hCitH3-mAb) in Healthy Volunteers and in Patients With Mild-to-Moderate ARDS: Part A (Healthy Volunteers)
This Phase 1/2A, randomized, double-blind study will evaluate the safety, tolerability, and pharmacokinetics (PK) of HT31-1 (hCitH3-mAb) in healthy adult volun…
Protocolized Weaning of High-Flow Nasal Cannula in Adult Patients: A Stepped-Wedge Cluster Randomized Trial (PRO-WEAN HFNC)
High-flow nasal cannula (HFNC) is a type of oxygen therapy commonly used in adults with breathing problems. While HFNC can help patients avoid breathing tubes …
Blood-based Biomarkers of Acute Lung Injury/Acute Respiratory Distress Syndrome
Acute Lung Injury (ALI) and Acute Respiratory Distress Syndrome (ARDS) is a condition where high levels of inflammation damage the lung. This is a highly morbi…
Research Respiratory Tract Procedures
This study will collect fluid and tissue specimens from the lungs and nose of healthy people and people with a history of lung infections. The specimens will b…
Transcranial Doppler Assessment of Cerebral Autoregulation and Blood Flow Velocity Patterns in Critically Ill Children: A Prospective Observational Study
This study uses a non-invasive (external) ultrasound test called Transcranial Doppler (TCD) to measure how blood flows through the major arteries of the brain …
Pharmacokinetics and Placental Transfer of Caffeine: a Pilot Trial of Caffeine Administration Across the Second and Third Trimesters of Pregnancy
The goal of this study is to learn how a pregnant person's body processes caffeine and how much caffeine crosses the placenta to the baby. A small dose of caff…
Lung and Heart Function Across Decades of Life in Healthy Population
The main objective of this study is to develop baseline "normal" reference values of both lung and heart function for healthy adults within the age range relev…
The PEARL Trial: A Randomized Trial of Amnioinfusion's Protective Effects on Respiratory and Longitudinal Pediatric Outcomes After Intrapartum Thick Meconium Exposure
Thick meconium in the amniotic fluid occurs in about one out of seven pregnancies and increases the chance that a newborn may have breathing problems after bir…
A Phase 1/2a Trial of the Safety, Tolerability and Immunogenicity of PIV5-vectored RSV Vaccine (BLB-201) in RSV Seronegative and Seropositive Infants and Children
This Phase 1/2a trial is a randomized, placebo-controlled trial to evaluate the safety, tolerability and immunogenicity of two ascending doses (10\^6 PFU and 1…
Predictive Value of Lung Ultrasound for Respiratory Decompensation in Late Preterm Neonates
Respiratory morbidity presents a significant clinical challenge in the neonatal period, and an individual patient's clinical course is often difficult to predi…
A Prospective Randomized Controlled Trial Comparing High-Flow Nasal Cannula Versus Noninvasive Ventilation on Reintubation and Post-Extubation Respiratory Failure in High-Risk Patients With Systolic Heart Failure
This prospective, open-label randomized controlled pilot trial will enroll participants at the Yale New Haven Hospital. Patients with systolic heart failure, d…
Utilization of Lung Ultrasound Score in Decision for Minimally Invasive Surfactant Administration: A Pilot Study
This prospective randomized controlled study aims to determine if using a lung ultrasound score can lead to a faster diagnosis of severe respiratory distress s…
