St. Jude Tracking of Viral and Host Factors Associated With COVID-19

This is a prospective adaptive cohort study of St. Jude employees to determine the rate of SARS-CoV-2 infections that are asymptomatic and to evaluate immunological responses to SARS-CoV-2 infection. Primary Objectives To estimate the proportion of asymptomatic infection with SARS-CoV-2 infection in a population of SARS-CoV-2-naïve adult St. Jude employees To comprehensively map CD4 and CD8 T cell epitopes and response magnitudes to SARS-CoV-2 infection in a population of SARS-CoV-2-naïve adult St. Jude employees who acquire SARS-CoV-2 infection Secondary Objectives To establish seroprevalence of SARS-CoV-2-specific antibodies at baseline, and identify the rate of seroconversion to SARS-CoV-2 in a population of presumably naïve adult St. Jude employees To identify features of T cell responses at baseline and during SARS-CoV-2 infection that are associated with protection against symptomatic or severe COVID-19 disease in a population of adult St. Jude employees Exploratory Objectives To establish additional immunological features including host immune or receptor polymorphisms associated with response to SARS-CoV-2 infection To explore SARS-CoV-2 diversity and specific features in a circumscribed population To describe the presence, characteristics, and proportion of short-term re-infection To determine if an association between SARS-CoV-2 viral load in nasal swab specimens and COVID-19 symptoms can be identified in a population of adult St. Jude employees who acquire SARS-CoV-2 To explore the laboratory and clinical response to SARS-CoV-2 vaccine in a population of adult St. Jude employees with and without a history of SARS-CoV-2 infection

Phase 1 Study to Assess Safety, Reactogenicity and Immunogenicity of the HDT-301 Vaccine Against COVID-19

This is a phase I, open label, dose ranging clinical trial in healthy males and non-pregnant females, 18 to 55 years of age, inclusive, who are SARS-CoV-2 seronegative at screening. The trial is designed to assess the safety, reactogenicity and immunogenicity of HDT-301, which is a novel Lipid-Inorganic Nanoparticle (LION™) formulated replicating RNA-based vaccine that encodes for a full-length spike (S) protein of the SARS-CoV-2 virus. As a replicating mRNA vaccine, HDT-301 has the potential to allow the advantages of dose sparing, and possibly administration as a single dose, compared with other mRNA platforms. Enrollment will occur at one domestic site. 78 subjects will receive two intramuscular (IM) injections of HDT-301 at a dose of 1 µg, 5 µg and 25 µg on either Days 1 and 29 or on Days 1 and 57. ELISA IgG responses will be the primary endpoint assessed for dose-response and, for post dose one responses, as an initial exploration of feasibility of a one-dose strategy. Scheduled interim immunogenicity evaluations will be conducted for pre-specified timepoints. Subjects will be followed for safety and immunogenicity through 12 months after the second vaccination. The primary objective is to evaluate the safety and reactogenicity of a 2-dose vaccination schedule of HDT-301, with the second dose given at a 28 or 56 day interval, across 3 dosages in healthy adults.

Monitoring Serologic Response to Severe Acute Respiratory Syndrome-2 (SARS-COV-2)/COVID-19 in Children

Individuals susceptible to SARS-CoV-2 and the illness it causes (COVID-19) are comprised of heterogeneous populations with a large risk spectrum for more severe disease. Pre-existing risk factors for a more severe course include respiratory and cardiovascular disease, morbid obesity, diabetes, underlying kidney or liver disease, and immunocompromised status. Whether children and young adults with inflammatory bowel disease (IBD) or juvenile idiopathic arthritis (JIA) receiving immunomodulating biologic and other therapies which are known to increase risk of viral infection are at increased risk of complications from COVID-19 or post-infectious co-morbidities, including the recently described multi inflammatory syndrome (MISC), is entirely unclear. This research focuses on the heretofore uncharacterized immune response to SARS-CoV-2 infection in children and young adults with IBD or JIA who are receiving maintenance immunosuppressive biologic therapies. Given the large Connecticut based infusion program, in a region of the United States with a recent large outbreak of COVID-19, the investigators have a unique opportunity to address a glaring knowledge gap in this unique pediatric, adolescent, and young adult population. The investigators will longitudinally determine antibody development and durability to SARS-CoV-2 in approximately 450-500 children and young adults with IBD or JIA receiving biologic therapy over a two year period using a highly sensitive and specific quantitative assay utilizing novel technology. This period will include a return to school or work for many with likely resurgent infections, as well as the possible introduction of anti-SARS CoV-2 vaccines. The specific aim is to study the acute and convalescent antibody responses to SARS-CoV-2 infection in a cohort of children and young adults receiving infusions of biologic therapies for IBD and JIA.

Pediatric SARS-CoV-2 and MIS-C Long-term Follow-up

This is a multisite prospective observational study to evaluate the clinical sequelae of symptomatic and asymptomatic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in the pediatric population, including coronavirus disease 2019 (COVID-19) and multisystem inflammatory syndrome in children (MIS-C), and characterize the immune response associated with these clinical presentations. Patients aged 21 years and younger with laboratory confirmed history of symptomatic or asymptomatic SARS-CoV-2 infection will visit the study sites for clinical and research evaluations and sample collection at schedules dependent on time since infection. Patients enrolled within 12 weeks after acute infection or positive test will be part of the "recovery group" and will attend study visits at baseline, every 3 months for the first 6 months, and subsequently every 6 months for a total of 3 years. Patients enrolled more than 12 weeks after acute infection or positive test will be in the "convalescent group" and will attend study visits at baseline and subsequently every 6 months for a total of 3 years. Household contacts of the infected patients will serve as a control group and will attend visits for evaluations and sample collection at baseline and every 12 months for a total of 3 years. This protocol will establish a cohort of pediatric patients recovered from SARS CoV-2 infection and a biorepository for evaluation of the potential roles of host genetics, immune response, and other possible factors influencing long-term outcomes. Parents or guardians of participants in all cohorts will also be enrolled for limited participation to complete questionnaires about how the family is impacted by the participant's health and SARS-CoV-2

COVID-19 (SARS-CoV-2) in Urine and Semen

This study is part of the current global emergency scenario due to infection with Coronavirus, SARS-CoV-2 as indicated by the international taxonomy. Study aim is to investigate the possibility of the presence of the virus within the seminal fluid and in the urine of infected patients, both during the acute phase and remotely. Current evidences show that Coronaviruses can be present inside the testicle and sperm in other species, such as in feline and avian models. In human beings, current researches have mixed results regarding the presence of SARSCoV-2 in urine, as several studies with a large sample found no traces of the same with Real-Time Reverse method Transcriptase - Polymerase Chain Reaction or with method of nucleic acid amplification. By contrast, in just over 6% of 58 patients with Real Time Polymerase Chain Reaction method have found the presence of SARS-CoV-2 in the urine, even at a distance from the last negative nasopharyngeal swab. Given the topicality of the problem, our study has the objective of specifically researching the presence and possible persistence over time of SARS-CoV-2 in seminal fluid and urine. A saliva sample will also be collected as a control. At the moment there are no studies in literature that tested this possibility. If confirmed, it would lead to find out another potential method of transmission, the sexual one, in asymptomatic patients or apparently no longer infectious with negative buffer. The rationale for our study is the evidence that in other species this type of transmission by coronaviruses is possible and that at present it has not been verified in mankind. The relevance of the study would be both in the case of a negative result, as the first study in its generally, both in the case of a positive result, due to the possibility of introducing new prevention measures in the long run.

The Covid-19 HEalth caRe wOrkErS (HEROES) Study

Since December 2019 the world has been shaken with an enormous global threat: the Covid-19 pandemic. This new kind of coronavirus is generating an unprecedented impact both on the general population and on the healthcare systems in most countries. Health services are trying to expand their capacity to respond to the pandemic, taking actions such as increasing the number of beds; acquiring necessary equipment to provide intensive therapy (ventilators), and calling retired health professionals and health students so they can assist the overwhelmed health care workforce. Unfortunately, these organizational changes at health facilities, along with the fears and concerns of becoming ill with the virus or infecting their families, put an enormous emotional burden on workers in health services which may lead to negative outcomes on mental health in this population. Recent cross-sectional studies in China indicate that health service workers exposed to people with Covid-19 reported higher rates of depressive and anxious symptoms. This negative impact on mental health among health workers in China has also been informally reported in other countries where the Covid-19 pandemic has been devastating in its effects (such as Spain and Italy), as well as in countries where the pandemic is becoming a growing public health problem. This is particularly relevant in regions with fewer resources (Latin America, North Africa), where there are limited means and the response from the health system is usually insufficient. Moreover, it is necessary to study these negative effects longitudinally considering that some effects will appear over time (post-traumatic stress). The COVID-19 HEalth caRe wOrkErS (HEROES) study is a large, bottom-up, South-North initiative aimed to evaluate the impact of the COVID-19 pandemic on the mental health of health care workers (HCWs). HEROES encompasses a wide variety of academic institutions in 19 LMICs and 8 HICs, in partnership with the Pan American Health Organization (PAHO) and with support from the World Health Organization (WHO). The HEROES study is led by Dr. Rubén Alvarado at University of Chile, and Dr. Ezra Susser and Franco Mascayano at Columbia U Mailman School of Public Health.
