NCT05468736
This is a Phase 2/3 randomized, observer-blinded, placebo-controlled, age de-escalation trial to evaluate the safety and immunogenicity of 2 primary doses of SARS-CoV-2 rS with Matrix-M™ adjuvant (NVX-CoV2373) given 21 days apart and NVX CoV2373 or a variant-based vaccine given as a booster dose or at crossover in pediatric participants (3 age cohorts; 6 to \< 12 years, 2 to \< 6 years, and 6 to \< 24 months of age). Each age cohort will be conducted in 2 parts starting with the oldest age cohort (6 to \< 12 years of age).
NCT05004181
This trial consisted of three parts, Part A, Part B, and Part C, and evaluated the safety and immunogenicity of a third (booster) injection of the multivalent vaccine BNT162b2 (B.1.1.7 + B.1.617.2), and the safety and immunogenicity of a third booster injection of the monovalent vaccine BNT162b2 (B.1.617.2) or BNT162b2 (B.1.1.7), in participants who had received two doses of the parent vaccine BNT162b2 at 30 µg, at least 6 months after the second dose of BNT162b2. It also evaluated the safety and immunogenicity of a three-dose regimen of BNT162b2 (B.1.1.7 + B.1.617.2) in participants who had not received prior Coronavirus Disease 2019 (COVID-19) vaccination. In addition, the safety and immunogenicity of BNT162b2 (B.1.1.529.1) or BNT162b2 given as a third or fourth vaccine dose to RNA COVID-19 vaccine-experienced participants with history of SARS-CoV-2 Omicron variant infection was evaluated and contrasted with the natural immune response reached after infection with the SARS-CoV-2 Omicron variant in RNA COVID-19 vaccine-experienced participants.
NCT04904549
The purpose of this Phase III study is to assess the efficacy, safety, and immunogenicity of two CoV2 preS dTM-AS03 vaccines (monovalent and bivalent) as part of primary series vaccinations in a multi-stage approach, as well as a booster injection of a CoV2 preS dTM-AS03 vaccine, in adults 18 years of age and older. A total of approximately 21 046 participants are planned to be enrolled (5080 per study intervention group in Stage 1 and 5443 per study intervention group in Stage 2). Initial, double-blind, primary series study design is planned for 365 days post-last Initial injection (ie, approximately 386 days total) for each participant. Based on decisions of the Study Oversight Group, Stage 1 and Stage 2 participants will be invited to participate in an unblinded Crossover / Booster study design with duration as follows: * For participants who initially received vaccine: 12 months post-booster (ie, approximately 18 to 24 months) * For participants who initially received placebo: ≥ 4 months post-last dose of the primary series + 12 months post-booster (ie, approximately 28 to 34 months) * For participants who do not consent to continue in the unblinded Crossover / Booster part of the study, all study procedures will be stopped and participants will be discontinued from the study.

Interventional, randomized, double-blind, placebo-controlled study encompassing 2 development phases (Phase 2 and Phase 3).
NCT04924660
The overarching goal of the Master Protocol is to find effective strategies for inpatient management of patients with COVID-19. Therapeutic goals for patients hospitalized for COVID-19 include hastening recovery and preventing progression to critical illness, multiorgan failure, or death. Our objective is to determine whether modulating the host tissue response improves clinical outcomes among patients with COVID-19. The primary analysis will include data from NCT05593770.
NCT04382586
The primary objective of this study was to evaluate if the addition of zanubrutinib to supportive care increases the respiratory failure-free survival rate at Day 28 in participants hospitalized for Corona Virus Disease 2019 (COVID-19) and pulmonary distress not receiving mechanical ventilation.
NCT05817045
This is a randomized, double-blind, sham controlled, stratified, pivotal efficacy and safety study of the EmitBio RD-X19 treatment device in Individuals 40 Years of age and older with Mild COVID-19 in the at-home setting.
NCT05164133
This is a single-arm, open-label study to assess the pharmacokinetics, pharmacodynamics, safety, and exploratory efficacy of tocilizumab (TCZ) for the treatment of pediatric patients from birth to less than 18 years old hospitalized with COVID-19 and who are receiving systemic corticosteroids and require supplemental oxygen or mechanical ventilation.
NCT05487040
The purpose of this study is to learn about the side effects (safety) of the study medicine PF-07321332 (nirmatrelvir)/ritonavir for the treatment of mild to moderate COVID-19 infection in adults with severe renal impairment. The study will also look at the amounts of study drug in your blood. There will be 24 participants in this study; 12 of them will have severe renal impairment and not be on hemodialysis and 12 of them will be on hemodialysis. All participants in this study will take PF-07321332 (nirmatrelvir)/ritonavir by mouth for 5 days. During this time, they will have to collect blood samples to measure the study drug levels in their blood. After taking the study drug for 5 days, the participants will have follow-up visits for about another 28 days for a total of about 34 days in the study. The study team will check how each participant is doing during regular visits at the study clinic.

NCT04678193
Researchers are creating real-time epidemiology registry to evaluate the efficacy of COVID-19 subject risk assessment scores based on recording of symptoms, biomarkers, chronic illness and mental health assessments with digital technology using wearables and mobile app tools. Researchers aim to study in Phase 1, epidemiological variations in COVID-19 presentation in both PCR positive and negative subjects in the registry. Assessment of variables, predictive modeling of variables that impact severity of COVID-19 positive and negative subjects and assessment of predictors for post COVID-19 complications. In Phase 2, 2700 subjects with COVID-19 positive test will be studied in the intervention group comparing ECL-19 vs placebo with primary end point of hospital admission assessment. Treatment strategy for PCR positive COVID-19 subjects in the registry who are in Stage I of the disease process with ECL-19 drug compared to placebo in reducing hospital admissions
