Study to Describe the Safety, Tolerability, Immunogenicity, and Efficacy of RNA Vaccine Candidates Against COVID-19 in Healthy Individuals

This is a Phase 1/2/3, randomized, placebo-controlled, observer-blind, dose-finding, vaccine candidate-selection, and efficacy study in healthy individuals. The study consists of 2 parts: Phase 1: to identify preferred vaccine candidate(s) and dose level(s); Phase 2/3: an expanded cohort and efficacy part. The study will evaluate the safety, tolerability, and immunogenicity of 3 different SARS-CoV-2 RNA vaccine candidates against COVID-19 and the efficacy of 1 candidate: As a 2-dose (separated by 21 days) schedule; At various different dose levels in Phase 1; As a booster; In 3 age groups (Phase 1: 18 to 55 years of age, 65 to 85 years of age; Phase 2/3: ?12 years of age [stratified as 12-15, 16-55 or >55 years of age]). The candidate selected for efficacy evaluation in Phase 2/3 is BNT162b2 at a dose of 30 µg. Participants who originally received placebo will be offered the opportunity to receive BNT162b2 at defined points as part of the study. In order to describe the boostability of BNT162, and potential heterologous protection against emerging SARS-CoV-2 VOCs, an additional dose of BNT162b2 at 30 µg will be given to Phase 1 participants approximately 6 to 12 months after their second dose of BNT162b1 or BNT162b2. This will provide an early assessment of the safety of a third dose of BNT162, as well as its immunogenicity. The assessment of boostability will be further expanded in a subset of Phase 3 participants at selected sites in the US who will receive a third dose of BNT162b2 at 30 µg or a third and potentially a fourth dose of prototype BNT162b2VOC at 30 µg (BNT162b2s01, based upon the South African variant and hereafter referred to as BNT162b2SA). A further subset of Phase 3 participants will receive a third, lower, dose of BNT162b2 at 5 or 10 µg. To further describe potential homologous and heterologous protection against emerging SARS-CoV-2 VOCs, a new cohort of participants will be enrolled who are COVID-19 vaccine-naïve (ie, BNT162b2-naïve) and have not experienced COVID-19. They will receive BNT162b2SA given as a 2-dose series, separated by 21 days.

ReSET Aim 1b: Restarting Safe Education and Testing for Children With Medical Complexity - COVID-19 Testing in School With Children and Staff

The Coronavirus Disease 2019 (COVID-19), caused by the SARS-CoV-2 virus, is a worldwide pandemic that has resulted in large-scale quarantines in cities, states, and countries throughout the world. SARS-CoV-2 is a respiratory virus that is most commonly spread via contact with infective respiratory droplets and aerosols produced by coughing, sneezing, talking, and singing. Children with medical complexity (CMC), i.e., children with multiple severe chronic conditions, high resource use, severe functional limitations, and substantial family-identified service needs, are a medically vulnerable population for the development of severe COVID-19. Deciding to send CMC to school poses a major dilemma to families wanting to minimize severe COVID-19 risk. School personnel also face risks when CMC attend school. Despite these challenges, achieving in-person school attendance is critical for CMC. Compared to non-CMC, academic and social development for most CMC hinges on being at school. Severe intellectual and developmental disability impairs one's ability to engage with online platforms. Health-promoting services delivered at school, e.g., physical, occupational, and speech therapy, are likely less effective when delivered virtually. Parents of CMC, already disproportionately unemployed due to their child's care needs, experience added employment strain when their child is out of school. The study objective is to increase the safe return to school for CMC by 1) evaluating the feasibility of school-based COVID-19 testing strategies and 2) identifying parent and staff perceptions of testing and school attendance. A related study (ReSET Aim 1a, NCT04895085) will evaluate the same factors in home-based testing strategies in CMC exclusively.

Antiviral Activity and Safety of Remdesivir in Bangladeshi Patients With Severe Coronavirus Disease (COVID-19)

Background - A novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was first identified in December 2019 as the cause of a respiratory illness COVID-19 in Wuhan City, China. WHO declared a public health emergency outbreak of this virus on 30 January 2020 and declared COVID-19 a global pandemic on 11 March, 2020. Bangladesh reported its first case on March 8, 2020 and first fatality on April 1, 2020. Bangladesh had shown a staggered course of COVID-19 transmission initially but a surge in cases was observed from April, 2020. Remdesivir remains as the only potential therapy for the treatment of COVID-19 till date. Based on several pre-clinical studies in SARS-CoV and MERS-CoV infections, Animal trials in COVID-19 and data from human trials, this randomized, controlled, open label trial will evaluate the antiviral activity and safety of Remdesivir in Bangladeshi hospitalized patients with severe COVID-19. This study finding will provide knowledge if Remdesivir is effective enough to treat Bangladeshi COVID-19 hospitalized patients with adequate safety and tolerability. The result of this study will help the key opinion leaders regarding the matter, to take appropriate decision regarding usage of Remdesivir for the treatment of COVID-19 in Bangladesh. Study Procedure - All patients will receive the standard medical care for COVID-19+ve at the respective hospitals. Vital signs will be recorded every 24 hrs for 1st 5 days then once in 2 days till discharge or as per the discretion of the attending physicians. After screening the COVID-19 confirmed patients will be randomized into 2 treatment arms. Patient's safety assessment e. g. blood parameters (CBC, Creatinine, SGPT, RBS, Creatinine, Creatinine Clearance) will be done on screening, day 5 and day 14 or discharge; Chest X-ray and ECG on screening and day 14 or discharge. SARS-CoV-2 (viral load) will be looked in on day 5, day 10 and day 14 or at the time of discharge. In case any study patient deteriorates during the study period will be managed as per the guideline of that particular hospital and if needed will be shifted to ICU. Patients who will recover will be discharged as per the national guideline for the COVID-19 hospitalized patients. Patients will be contacted at 28 days either over phone or in person to get their health status since discharge.

A Longitudinal Study of COVID-19 Sequelae and Immunity

Background: COVID-19 is a disease caused by the SARS-CoV-2 virus. It infects the respiratory tract. Some people who get COVID-19 have only mild symptoms. But for others, infection leads to pneumonia, respiratory failure, and, in some cases, death. Researchers want to learn more about any effects that may persist after people recover from COVID-19. Objective: To learn about any long-term medical problems that people who have recovered from COVID-19 might have, and whether they develop an immune response to SARS-CoV-2 that provides protection against reinfection. Eligibility: People age 18 and older who have recovered from documented COVID-19 or were in close contact with someone who had COVID-19 but did not get the infection Design: Participants will be screened over 2 visits. During visit 1, they will answer questions about any symptoms they are having and will be tested for SARS-CoV-2 infection which will involve a nasal swab sample or other FDA approved test. If the test is negative, they will proceed to the second visit, which will include: Physical examination Medical history Mental health interview (which may be recorded if the participant agrees) Chest x-ray (for recovered COVID-19 participants only) Blood and urine tests Pregnancy test (if needed) Lung function test (for recovered COVID-19 participants only) 6-minute walk test (for recovered COVID-19 participants only) Questionnaires about their general and mental health Leukapheresis to collect white blood cells (optional). Participants will be put into 1 of 2 groups: the COVID-19 group or the close contact group. Participants will have study visits every 6 months for 3 years. They will repeat some of the screening tests. Participants in the COVID-19 group may have visits more often if they develop symptoms that suggest re-infection with SARS-CoV-2....
