COVID19 Clinical Trials in Dallas, TX

Treatments are needed to improve outcomes among patients hospitalized for COVID-19, including direct-acting antiviral (DAA) agents to mitigate the pathology driven by ongoing viral replication. This trial will evaluate S-217622 (ensitrelvir), an anti-SARS-CoV2 3C-like protease inhibitor (PI) developed by Shionogi &; Co. Ltd. The study design is a randomized, placebo-controlled, multi-center international clinical trial that will evaluate the clinical efficacy of ensitrelvir when given in addition to standard of care (SOC) for inpatients with COVID-19. The SOC will be determined by local established guidelines and may include additional DAA (e.g., remdesivir) and immunomodulatory treatment strategies. Certain SOC treatments will be pre-specified prior to randomization. Read Less

The purpose of this study is to understand the safety and effects of a combined influenza and COVID-19 vaccine. This combined vaccine is compared to separate vaccines for the protection against influenza and SARS-CoV-2. Influenza and COVID-19 are diseases that can spread easily from one person to another and cause body aches, fever, cough, and other symptoms. Giving both influenza and COVID-19 vaccines together against influenza and SARS-CoV-2 could provide great benefits to both patients and caregivers in terms of simple and easy care. Around 9000 participants will be assigned into 1 of 4 vaccination groups (Group A, B, C or D) by chance. Cohort 1: Around 4500 participants will be assigned by chance to one of the following: Group A:Influenza and COVID-19 combination A vaccine, given at the same time in the right arm and placebo (an injection consisting of just salt water and no medicines in it) in the left arm. Group B: COVID-19 vaccine, given at the same time to the right arm and licensed influenza vaccine in the left arm. Cohort 2: Around 4500 participants will be assigned by chance to one of the following: Group C: Influenza and COVID-19 combination B vaccine, given at the same time in the right arm and placebo in the left arm. Group D: COVID-19 vaccine, given at the same time in the right arm and licenced influenza vaccine in the left arm. All participants will receive 2 injections as per their assigned study group at Visit 1. The participants will be followed for about 6 months. During this time, the study will compare participant experiences when they receive a combined vaccination to when they receive separate vaccinations. This will help understand if the study medicine is safe. Read Less

COVID-19 can trigger a dysregulated immune response, and previous studies have shown that immune modulation can improve outcomes in hospitalized patients. This trial is designed to determine whether intensification of immune modulation early in the course of the disease (while patients are on low flow oxygen) with abatacept (active arm) combined with standard of care (SOC) improves recovery as compared with placebo + SOC (placebo arm). For both groups, intensification of immunomodulation will be provided as part of SOC in case of signs of disease progression (patient requires high flow nasal oxygen (HFNO) or more support) and/or if the patient has rapidly increasing oxygen requirement.

The study investigators are interested in learning more about how drugs, that are given to children by their health care provider, act in the bodies of children and young adults in hopes to find the most safe and effective dose for children. The primary objective of this study is to evaluate the PK of understudied drugs currently being administered to children per SOC as prescribed by their treating provider. Read Less

The purpose of the study is to evaluate whether bemnifosbuvir (BEM) is effective and safe in adults with COVID-19 who do not need to be in the hospital but who are at high risk for progression to severe disease. Eligible subjects will be randomly assigned (by chance) to receive BEM or matching placebo orally for 5 days. Co-administration of locally available standard of care (SOC) is allowed. The total duration of the study is 60 days. Read Less

The purpose of this clinical trial is to learn about the safety, extent of the side effects, and immune responses of the study vaccine (called variant-adapted BNT162b2 RNA-based vaccine) in healthy children. The trial is divided into 5 individual studies or substudies based on age group and prior history of COVID-19 vaccinations. All participants in each of the 5 sub-studies will receive study vaccine as a shot depending on what group they are in. Substudy A design: Phase 1 includes participants 6 months through less than 4 years 3 months of age who have not received a previous coronavirus vaccination (COVID-19 vaccine naïve) and will receive 3 doses of study vaccine as their initial series, followed by a fourth dose of study vaccine. Phase 2/3 includes participants 6 months through less than 5 years of age who have not received a previous coronavirus vaccination (COVID-19 vaccine naive) and will receive 1, 2, or 3 doses of study vaccine, depending on what group they are in. Substudy B design: includes participants 6 months through less than 5 years of age who have either received 2 or 3 prior doses of BNT162b2 and will receive study vaccine as their third or fourth dose. Substudy C design: Phase 1 includes participants 6 months through less than 5 years of age who have received 3 prior doses of BNT162b2 and will receive study vaccine as their fourth dose. Substudy D design: includes participants 5 through less than12 years of age who have received 2 or 3 prior doses of BNT162b2 and will receive study vaccine as their third or fourth dose. Substudy E design: includes participants 2 through less than 12 years of age who have not received a previous coronavirus vaccination (COVID-19 vaccine naive) and will receive a single dose of study vaccine.

Adults who do not have major health, kidney, gastrointestinal disease will be randomized to receive oral mitoquinone/mitoquinol mesylate (Mito-MES) versus placebo to prevent the development and progression of COVID-19 after high-risk exposure to a person with confirmed SARS-CoV-2 infection.

The primary objective of the Outpatient Treatment with Anti-Coronavirus Immunoglobulin (OTAC) (INSIGHT 012) trial is to compare the safety and efficacy of a single infusion of anti-COVID-19 hyperimmune intravenous immunoglobulin (hIVIG) versus placebo among adults with recently diagnosed severe acute respiratory syndrome - coronavirus 2 (SARS-CoV2) infection who do not require hospitalization. The primary endpoint of this double-blind randomized trial is a five-category ordinal outcome that assesses the participant's clinical status seven days after the infusion of hIVIG or placebo. Asymptomatic and no limitations in usual activity due to COVID-19 Mild COVID-19 illness or minor limitations to usual activity Moderate COVID-19 illness and with major limitations to usual activity Severe COVID-19 or serious disease manifestation from COVID-19 Critical illness from COVID-19 or Death Two strata of participants will be identified for analysis purposes. Stratum 2 will be participants who receive direct-acting antivirals (DAAs) or other anti-SARS-CoV2 agents that are approved/available and recommended for use as part of standard of care (SOC), estimated to be about 20% of participants. Stratum 1 will be participants who do not receive this agents, estimated to be about 80% of participants. Read Less

A randomized, observer-blind, placebo-controlled immuno-bridging, and broadening study to demonstrate the equivalence of the immune response between participants enrolled in Phase 3 efficacy trial in India and demographically diverse healthy adult participants in the US which matched in age and vaccine formulation setting to whom those efficacy results are extrapolated; and to assess the broadening of the BBV152 in participants who previously received two shots of messenger ribonucleic acid (mRNA) COVID-19 vaccine at least 6 months earlier or one-shots of viral vector J&J/Janssen COVID-19 vaccine at least 2 months earlier. Safety and tolerability evaluation is a secondary endpoint. Read Less
