118 Clinical Trials for Various Conditions
For the development of a Point of Care IVD test kit for acute phase disease detection against a variety of bacterial and viral infections. Phase one includes 100 clinical diagnosed positive and 200 clinically "normal" serum and whole blood matched specimens for specificity and sensitivity determination for each marker. The positive samples must be IgM positive using any FDA cleared ELISA test kit. The negatives samples must be negative for IgM.
This single-dose trial will evaluate the efficacy of a novel ibuprofen formulation compared to placebo in patients with a fever due to an uncomplicated acute infection.
The purpose of the study is to describe the rate of occurrence of clinical diagnosis of acute respiratory infection (an infection that affects normal breathing) and different types of respiratory pathogens (harmful organisms) of new respiratory infections in a population at high risk for severe illness.
This study is designed to assess the causes and impact of acute respiratory illness (common colds, flu, bronchitis, pneumonia) in adults age 65 and older. One of the ways to determine the virus causing a particular illness is to get a blood specimen when a person is sick and again later and look for the body's specific responses that identify the virus. Approximately 3000 subjects will be evaluated and their medical records assessed for details of recent illness and general health to help in understanding the subjects' current illness.
The objective of this Phase 1 safety study is to provide access to the potential therapeutic benefit of EBOV convalescent plasma containing antibodies to EBOV. The risk of exposure to plasma from donors who may be infected with other transfusion-transmitted pathogens, not detectable by current licensed donor testing procedures, will be mitigated by using pathogen inactivation to minimize the risk of the TTI from these donors, who would otherwise be deferred and ineligible for blood donation.
The purpose of this study is to assess the efficacy (decrease in profound fatigue), safety and pharmacokinetics of RSLV-132 in subjects with long Corona Virus (COVID) syndome
The goal of this clinical study is to learn more about the study drug, obeldesivir (ODV; GS-5245), and how safe and effective it is in treating nonhospitalized adults with acute respiratory syncytial virus (RSV) infection. The researchers want to see if obeldesivir can help participants' symptoms get better faster. The primary objectives of this study are to evaluate the efficacy of ODV in reducing the duration of symptoms and to evaluate the safety and tolerability of ODV in nonhospitalized adult participants with acute RSV infection.
HCV infection is a global health problem. HCV mainly affects liver cells and causes the liver to become inflamed and damaged. This study will evaluate how safe and effective glecaprevir/pibrentasvir (GLE/PIB) is in adult and adolescent participants with acute HCV infection. GLE/PIB is an approved drug for the treatment of chronic HCV. Around 283 participants at least 12 years of age with acute HCV Infection will be enrolled in approximately 70 sites worldwide. Participants will receive oral tablets of GLE/PIB once daily (QD) for 8 weeks and will be followed for 12 weeks after the end of treatment. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, monitoring for side effects and completing questionnaires.
The purpose of this study was to assess the efficacy of a fixed dose combination (FDC) of glecaprevir/pibrentasvir (G/P) given for 4 weeks for treatment of acute hepatitis C (HCV), with or without HIV-1 coinfection.
Early identification of acute HCV infection is essential to prevent chronic infections and the long-term liver disease complications that may occur. Early identification and treatment of HCV during the acute phase can result in significantly higher response rates with shorter durations of therapy. Pegylated-interferon alfa (PEG-IFN) was the typical treatment for HCV infection. Participants subcutaneously inject PEG-IFN where the average duration of treatment was approximately 20 weeks. With the advancement of direct-acting antivirals (DAAs), it was possible to see if a new DAA might be non-inferior compared to (PEG-IFN). The study was designed to see if a fixed-dose combination tablet can replace the old HCV treatments by being more effective, safer and better tolerated in HIV-infected participants with new HCV infection. The study was a Phase I, open-label, two cohort clinical trial, in which 44 acutely HCV-infected HIV-1 positive participants were enrolled. Participants in each cohort were evaluated in two steps: on treatment (Step 1) and follow-up after discontinuing study treatment (Step 2). The cohorts were enrolled sequentially. Participants in Cohort 1 were enrolled and administered oral Sofosbuvir (SOF) in combination with weight-based ribavirin (RBV). Participants in Cohort 2 were enrolled and administered an oral fixed dose combination of Ledipasvir/Sofosbuvir (LDV/SOF).
This study is designed to test the hypothesis that treatment of hepatitis C virus (HCV) infection during the first 6 months after acquiring HCV among people who already have pre-existing HIV infection will result in improved responses to HCV therapy with a shorter duration of infection.
Injection drug use accounts for transmission of a high proportion of Hepatitis C Virus (HCV) infections. The purpose of this trial is to investigate the effectiveness of pegylated interferon in treating injection drug users (IDUs) with acute HCV.
The study titled " The Effect of Definitive Identification of Viral Etiology in Emergency Department Patients with Acute Respiratory Infection on Antibiotic Utilization (RADIATE)" aims to investigate the effectiveness of a rapid diagnostic approach in reducing unnecessary antibiotic use in the emergency department (ED) for patients presenting with acute respiratory illness (ARI) due to a virus. Using a prospective design, eligible participants are individuals who visit the ED with complaints related to acute respiratory illness. The study will employ a single-arm consecutive enrollment approach. The intervention involves the implementation of a rapid point-of-care multiplex polymerase chain reaction (PCR) test to promptly identify the viral cause of the infection. By utilizing a rapid diagnostic tool to identify viral etiology, the study aims to provide healthcare professionals in the ED with more accurate information to guide treatment decisions. Ultimately, the goal is to decrease the unnecessary use of antibiotics for ARI's due to a virus, which has several negative outcomes including promotion of antibiotic resistance, exacerbating ED length of stay and encouraging unnecessary additional diagnostic tests.
Prospective, multi-center, observational, blinded study, enrolling pediatric and adult subjects. Eligible ED\\Urgent care and hospital admitted patients with symptoms consistent with acute bacterial or viral infection and healthy subjects will be recruited according to the eligibility criteria. Each participant will undergo a thorough investigation upon recruitment that includes documenting clinical, radiological, laboratory and microbiological information for determining their health status. Follow-up data will be collected via a phone call. Diagnostic performance of the MeMed BV™ Test for differentiating bacterial from viral infection will be assessed using an expert adjudication comparator method. The study will be run in a blinded fashion: site personnel will be blinded to the comparator method outcomes, and the expert panel will be blinded to the results of the index test. Results of the index test will not be revealed to the attending clinician and so will not influence patient management.
Following the sudden and unexpected emergence of influenza A(H1N1)pdm09 (2009 H1N1) virus, this observational study was initiated to estimate rates of morbidity and mortality and to examine predictors of severity among participants with 2009 H1N1 infection. In 2011, as surveillance indicated that 2009 H1N1 virus was co-circulating with other seasonal influenza A and B viruses worldwide, the protocol was expanded to include other influenza A subtypes and influenza B viruses. The current version of the protocol (released in August 2013) further broadens the scope of this observational study. With the recognition that novel respiratory viruses other than novel influenza A viruses, e.g., Middle East Respiratory Syndrome Coronavirus (MERS-CoV), could become prevalent and of major public health importance, the objectives of this protocol have been expanded.
The purpose of this study is to evaluate the effect of tozorakimab, as an add-on to SoC in patients with viral lung infection requiring supplemental oxygen, on the prevention of death or progression to IMV/ECMO.
Purpose: To determine the number of asymptomatic individuals who have antibodies to SARS-CoV-2, the virus which causes COVID-19
This study aims to use a clinically validated metagenomic next-generation sequencing (mNGS) assay to provide a demonstration of precision medicine for diagnosis of acute infectious disease in hospitalized patients. From June 2016 to June 2017, 200 patients will be enrolled from multiple hospitals in California and outside of California. Patients will be evaluated to determine the impact on the mNGS assay on diagnostic yield, hospital costs and clinical outcomes.
Allogeneic hematopoetic stem cell transplantation (SCT) is frequently complicated by life threatening viral reactivation. Conventional antiviral therapy is suboptimal for cytomegalovirus (CMV), adenovirus (AdV) and Epstein-Barr virus (EBV) and nonexistent for BK virus (BKV). An alternative approach to prevent viral reactivation is to infuse virus-specific cytotoxic T cells (CTL) prepared from the donor early after SCT. Such multivirus-specific CTL cells (MVST) have been successfully used in a number of centers to prevent or treat CMV, Ad and EBV. Activity of BKV-reactive cells has not been studied. Multi virus-specific T cells (MVST) are donor lymphocytes that are highly enriched for viral antigens and expanded in vitro before infusion into the transplant recipient. Viral reactivation is a particular problem inT cell depleted SCT. Median time to CMV reactivation is estimated as 28 days post T-depleted transplant, but infusion of MVST within the immediate post-SCT period has not been previously studied. This protocol will be the first of a planned series of cellular therapies to be layered on our existing T lymphocyte depleted transplant platform protocol 13-H-0144. The aim of this study is to determine the safety and efficacy of very early infusion of MVST directed against the four most common viruses causing complications after T-depleted SCT. GMP-grade allogeneic MVST from the stem cell donor will be generated using monocyte-derived donor dendritic cells (DCs) pulsed with overlapping peptide libraries of immunodominant antigens from CMV, EBV, Ad, and BKV and expanded in IL-7 and IL-15 followed by IL-2 for 10-14 days. A fraction of the routine donor leukapheresis for lymphocytes obtained prior to stem cell mobilization will be used to generate the MVST cells. MVST passing release criteria will be cryopreserved ready for infusion post SCT. Eligible subjects on NHLBI protocol 13-H-0144 will receive a single early infusion of MVST within 30 days (target day +14, range 0-30 days) post SCT. Phase I safety monitoring will continue for 6 weeks. Viral reactivation (CMV, EBV, Ad, BK) will be monitored by PCR by serial blood sampling. The only antiviral prophylaxis given will be acyclovir to prevent herpes simplex and varicella zoster reactivation. Subjects with rising PCR exceeding threshold for treatment, or those with clinically overt viral disease will receive conventional antiviral treatment. Patients developing acute GVHD will receive standard treatment with systemic steroids. These patients are eligible for reinfusion of MVST when steroids are tapered. The clinical trial is designed as a single institution, open label, non-randomized Phase I/II trial of MVST in transplant recipients, designed as 3-cohort dose escalation Phase I followed by a 20 subject extension Phase II at the maximum tolerated dose of cells. Safety will be monitored continuously for a period of 6 weeks post T cell transfer. The primary safety endpoint will be the occurrence of dose limiting toxicity, defined as the occurrence of Grade IV GVHD or any other SAE that is deemed to be at least probably or definitely related to the investigational product. The primary efficacy endpoint for the phase II will be the proportion of CMV reactivation requiring treatment at day 100 post transplant. Secondary endpoints are technical feasibility of MSVT manufacture, patterns of virus reactivation by PCR, and clinical disease from EBV, Ad, BK, day 100 non-relapse mortality.
This study will examine the safety of an experimental medication called Poly-ICLC, developed for preventing or reducing the severity of infections from influenza and other viruses acquired through the nose, mouth and lungs. The study is divided into two parts, in which Poly-ICLC is tested at different dose levels. Healthy people between 18 and 70 years of age who have no chronic medical problems may be eligible for this study. Participants undergo the following procedures: Part I * Up to 7 days before Poly-ICLC administration: Medical history, physical examination and blood tests. * Day 1: Nasal wash and Poly-ICLC administration. A small amount of salt water is placed into the front of the nose and then suctioned out. Poly-ICLC is then squirted into each nostril, one after the other, at a dose of 0.25, 0.5 or 1 mg. A small number of subjects are given a placebo (a solution with no active ingredient.) Subjects are observed in the clinic for 30 minutes after treatment. * Day 2: Subjects receive a second nasal wash and repeat blood tests. They keep a diary card for 1 week, recording any drug side effects. * Day 5: Subjects have repeat blood tests and a review of their diary card. The keep a diary card for another 3 weeks. * Day 12: Subjects are contacted by phone to review their diary card. * Day 28: Subjects are contacted by phone to review their diary card. Part II * Up to 7 days before Poly-ICLC administration: Medical history, physical examination and blood tests. * Day 1: Nasal wash and Poly-ICLC administration. Same as above for Part I participants. * Day 3: Subjects receive a second dose of medication and are observed again for 30 minutes. * Day 4: Subjects receive a second nasal wash and repeat blood tests. They keep a diary card for 1 week, recording any drug side effects. * Day 7: Subjects have repeat blood tests and a review of their diary card. The keep a diary card for another 3 weeks. * Day 14: Subjects are contacted by phone to review their diary card. * Day 28: Subjects are contacted by phone to review their diary card.
The main purpose of this study is to learn about the effectiveness of Pfizer's ABRYSVO vaccine. This vaccine helps to prevent infections caused by Respiratory Syncytial Virus (RSV). RSV is a virus that can cause infections in the airways. These symptoms can be cold-like symptoms, but in some cases can lead to severe symptoms or hospitalization. This study uses only healthcare data that are already collected from routine visits to healthcare providers. This means that participants will not be actively enrolled in the study and there are no study treatments. The study will look at data for about two years. This study will look at patient information from: * Adults ages 60 years and older * Adults who are eligible to receive the ABRYSVO vaccination Substudy A: * This study will assess the duration of protection of ABRYSVO in adults ages 60 years and older after completion of the original study. * The substudy will look at data from subsequent RSV seasons after the first dose of ABRYSVO for about 3 years. Substudy B: * This study will assess vaccine effectiveness of ABRYSVO after revaccination in routine use, pending ACIP recommendation for revaccination. * The substudy will look at data for about 2 years after revaccination.
Recent advances have been made in prevention of the viral infection via vaccines but there is still need for effective treatment options for patients. Novel therapies need to be developed to further improve clinical outcomes. The biggest medical challenge in the response to COVID-19 is ARDS requiring hospitalization in an intensive care setting and ventilator dependence. Intravenously administered umbilical cord derived exosomes and stem cells have been reported in literature to alleviate pulmonary distress in such patients. The purpose of this study is to explore the safety and benefits of intravenous administration of WJPure and EVPure in the treatment of COVID-19 patients with moderate to severe ARDS. .
This study will assess the acceptability, feasibility, and impact of game-based computer-delivered cognitive training on cognitive function in persons with cognitive symptoms that persist after recovery from acute coronavirus-19 (COVID) infection.
The purpose of this study is to evaluate the positivity rate of respiratory syncytial virus (RSV), influenza virus and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in high-risk participants presenting with acute respiratory infections (ARIs) in outpatient settings during the influenza/RSV season and to evaluate the association between lower respiratory tract disease (LRTD) and ARI-related hospitalization in participants positive for RSV.
The study will enroll up to 27,200 participants in order to demonstrate the efficacy of the active Ad26.RSV.preF-based study vaccine in the prevention of Reverse Transcription Polymerase Chain Reaction (RT-PCR) confirmed Respiratory Syncytial Virus (RSV)-mediated Lower Respiratory Tract Disease (LRTD) when compared to placebo in adults aged 60 years and above.
This multi-arm, multi-site study investigates the safety, tolerability, and efficacy of stem cell therapy for the treatment of various acute and chronic conditions. Clinically observed initial findings and an extensive body of research indicate regenerative treatments are both safe and effective for the treatment of multiple conditions.
The purpose of the study is to evaluate the efficacy of rilematovir compared to placebo treatment with respect to the clinical outcome on the RSV Recovery Scale (RRS).
The 2019-2020 COVID-19 pandemic is the largest outbreak in recent history. It is not known how long after someone gets sick with COVID-19 and recovers that they can still infect other people. It is also not known how quickly people make antibodies against the virus, which help clear infection from the body. The investigators will enroll 300 people who had COVID-19 based on lab testing or confirmed exposure to participate. An additional 25 participants who have never tested positive for COVID and have not had the vaccine will be enrolled as negative controls. Participants will complete a survey at enrollment. The investigators will also collect blood, nose swab, saliva, stool, semen, and breast milk to test for the virus. The investigators will ask participants to complete a survey and give specimens up to 12 times over 24 months. This information will be used to study how long the virus can live in different parts of the body, antibody development, and post-infectious complications. The investigators hope that this information will allow medical and public health providers to make recommendations to better care for patients in the convalescent phase of COVID-19 infection.
Background: Mitochondrial disease is a rare disorder. It can cause poor growth, developmental delays, muscle weakness, and other symptoms. The disease is usually inherited. It can be present at birth or develop later in life. Infection is a major cause of disease and death in people with this disease. Researchers want to learn more about these infections and the declining health of people who have this disease. To do this, researchers will study the DNA of people who become ill. Their DNA will be compared to the DNA of their household/family members. Objective: To learn more about how genes affect people with mitochondrial disease. Eligibility: People age 2 months and older with mitochondrial disease and their household/family members. .\<TAB\> Design: Participants will complete a questionnaire about their health history. Their medical records may be reviewed. They will give a blood sample. If the participant becomes ill, they may have a videoconference with a doctor or nurse at the NIH to perform a physical exam. They may be contacted after their illness to give updates on their health. They may be asked to give extra blood samples or complete extra questionnaires. Participants genetic data will be put into a database. The data will be labeled with a code and not their name. The data will be shared with other researchers. Participation lasts about 1 year. This may be extended if the participant is very ill.
Patient are being asked to provide respiratory and blood samples for a clinical research study because the patients have a virus called the novel coronavirus, or SARS-CoV-2, that causes the disease known as Covid-19. Investigators do not know a lot about this virus, including all the ways it travels from person to person. Investigators also do not know if a person will get sick or not from the virus after being in close contact with someone who has the virus. Because of this, investigators are performing research on the virus found in respiratory secretions to get more information on how investigators can best detect and treat this new virus in the future. Primary Objective * To determine the clinical characteristics and outcomes of Covid-19 in children. * To characterize the clinical risk factors of Covid-19 in children.. Secondary Objectives * To characterize the immunological risk factors and serologic response to SARS-CoV-2 infection in children.- To evaluate the duration of viral shedding in children. * To evaluate the duration of SARS-CoV-2 viral shedding in children. Exploratory Objective
