CIRV2 is a Phase IV randomized, open-label, trial of FDA-approved COVID-19 and/or influenza vaccines (no more than minimal risk) with longitudinal follow-up. In 2025 CIRV2 will compare immunogenicity and reactogenicity of the recombinant Novavax COVID-19 vaccine and the mRNA Pfizer-BioNTech COVID-19 vaccine.

The purpose of this study is to evaluate the efficacy and safety of mRNA-1283 and mRNA-1273 (variant formulations) in adults 50 to 64 years of age without high risk factors for severe COVID-19.

The objective of this protocol is to use a case-control paradigm to compare the response to an intravenous administration of kisspeptin in individuals with and without post-covid-19 syndrome. The study subjects will receive a single bolus of kisspeptin. This study will utilize the technique of frequent blood sampling (q10 minutes) to provide detailed neuroendocrine characterization of endogenous LH secretion before and after kisspeptin administration. This frequency of blood sampling is required to define the features of LH pulses.

The Metrix Respiratory Panel Test will be evaluated for use in Non-Laboratory settings in a home testing environment utilizing the clinical study design described herein. The study will take place in simulated home environments which will be set up within or near active clinical settings (e.g., urgent care facilities). This will be a prospective study conducted at three or more investigational sites located within the United States for the clinical validation of the Metrix Respiratory Panel Test for the detection of SARS-CoV-2, Influenza A, Influenza B, Respiratory syncytial virus, and Rhinovirus in anterior nares (AN) swab samples. Additional sites may be added to the study in order to meet minimum subject/sample enrollment requirements and geographic prevalence of respiratory virus infections. Comparator testing will be performed to determine the infection status of each sample for comparison to results generated by the candidate test. The primary comparator for the study will be an FDA-cleared assay for the detection of SARS-CoV-2, Influenza A, Influenza B, Respiratory Syncytial Virus, and Rhinovirus.

Coronaviruses (CoVs) have caused the severe acute respiratory syndrome (SARS) outbreak, the Middle East Respiratory Syndrome (MERS) outbreak, and now the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. Although there are several approved or authorized vaccines for SARS-CoV-2, there are currently no vaccines approved to prevent diseases caused by multiple different coronaviruses. Two countermeasures with promise for controlling coronavirus outbreaks are recombinant neutralizing antibodies and vaccines directed against the virus. Between these two countermeasures, the ultimate solution to control the current COVID-19 pandemic and future CoV outbreaks is a pancoronavirus vaccine. In particular, a vaccine that can induce broader protection and can prevent severe disease caused by current SARS-CoV-2 variants of concern would help mitigate significant morbidity and mortality following SARS-CoV-2 infection. Additionally, an optimal pancoronavirus vaccine would prevent severe disease from other SARS-related viruses in the genus of coronaviruses-betacoronavirus-that are responsible for past outbreaks or could cause the next major outbreak in humans. Such a broadly active coronavirus vaccine would be an impactful first step towards preventing all life-threatening coronavirus human disease. The proposed vaccine immunogen (Cov-RBD-scNP-001) is composed of an engineered receptor binding domain (RBD) of SARS-CoV-2 WA-1 covalently linked in vitro to the surface of a Helicobacter pylori ferritin protein nanoparticle (RBD-scNP). The RBD has been engineered at two sites to improve its expression. The protein nanoparticle is composed of 24 individual ferritin subunits each of which can have a SARS-CoV-2 WA-1 RBD attached to it via a nine amino acid linker. The protein nanoparticle will be delivered with 3M-052-AF adjuvant - a TLR 7/8 agonist.

The purpose of this study is to determine if immune responses differ when the mRNA COVID-19 vaccine is given through different delivery methods, including a needle-free injection system, or via intramuscular injection using needle and syringe

This is a randomized, placebo-controlled study. Patients with long COVID will be randomized to receive dapagliflozin or placebo for 12 months.

The goal of this clinical trial is to test two investigational COVID-19 booster vaccines, called CoTend-s3BXBB and CoTend-BXBB, in healthy volunteers ages 40-64. The CoTend-s3BXBB vaccine includes a component called "s3", which was designed to improve the body's response to the vaccine. CoTend-BXBB is the same vaccine without s3. The main questions the study aims to answer are: 1) Is the investigational vaccine safe? 2) Does "s3" lead to bigger, broader, and longer-lasting responses to the vaccine? 5 different doses of the vaccines will be studied. Participants will receive a single dose of either CoTend-s3BXBB, CoTend-BXBB, or placebo. Participants will be monitored for side effects. Saliva, nasal, and blood samples will be collected and immune responses to the vaccine will be measured.

Researchers are looking for other ways to prevent severe illness from COVID-19. COVID-19 is a virus that most often causes mild flu or cold-like symptoms. However, people with certain health conditions or other factors have a high risk (chance) of getting severely ill from COVID-19, which can require a hospital stay or lead to death. Some people who are high risk for severe illness may be unable to take certain treatments for COVID-19 because they are not available to them, or they take other medicines that may react with a treatment and cause an unwanted effect. Molnupiravir (MK-4482) is a study medicine designed to stop the COVID-19 virus from copying itself in the body (multiplying). The goal of this study is to learn if molnupiravir prevents severe illness from COVID-19 more than placebo in people who are high risk.

The goal of this pragmatic embedded open-label, 2 x 2 factorial phase II randomized controlled trial is to evaluate strategies to improve COVID-19 booster and influenza vaccine immunogenicity in people living with immunocompromising conditions (PLIC). The main questions it aims to answer are: 1. Is co-administration of seasonal inactivated influenza vaccine (IIV) with the most up-to-date recommended COVID-19 booster dose non-inferior in inducing a 1-month peak protective humoral response against COVID-19, compared to a strategy of sequential administration of COVID-19 booster dose followed by seasonal IIV given one month later? 2. Is the administration of the most up-to-date recommended COVID-19 booster doses at 3-month intervals superior at maintaining a longer term protective humoral immune response, compared to booster doses administered at 6-month intervals? Researchers will compare (1) COVID-19 and Influenza vaccines administered at Day 0 + COVID-19 Booster at a 3-month interval, (2) COVID-19 vaccine administered at Day 0 and Influenza vaccine administered at Day 28 + COVID-19 Booster at a 3-month interval, (3) COVID-19 and Influenza vaccines administered at Day 0 + COVID-19 Booster at a 6-month interval, and (4) COVID-19 vaccine administered at Day 0 and Influenza vaccine administered at Day 28 + COVID-19 Booster at a 6-month interval to see if median neutralization capacity of patient sera is non-inferior in the co- vs. sequential administration arms at 1-month after the initial COVID-19 booster and superior in the 3-month interval arms vs. the 6-month interval arms at 12 months after the initial COVID-19 booster. These outcomes will also be compared at 2-months for question 1 and 6-months for question 2. People living with immunocompromising conditions who take part in the trial will have blood samples drawn to verify immune response, be monitored for changes in clinical events and therapies, and complete questionnaires to verify adverse effects, quality of life and economic impact.

The purpose of this study is to investigate the immunogenicity of mRNA COVID-19 variant-containing vaccine formulations against the vaccine matched variants and newly emerged variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

The purpose of this project is to test the feasibility and safety of inhaled hydrogen gas (H2) administration as a rescue therapy during cardiac arrest requiring extracorporeal cardiopulmonary resuscitation (ECPR, i.e. mechanical circulatory support). Under exemption from informed consent, patients undergoing refractory cardiac arrest in the cardiac ICU at a participating center will be randomized to standard therapy with or without the administration of 2% hydrogen in gases administered via the ventilator and ECMO membrane for 72 hours.
