COVID19 Clinical Trials in San Antonio, TX

This study evaluates immunologic response following COVID-19 vaccination in children, adolescents, and young adults with cancer. Vaccines work by stimulating the body's immune cells to respond against a specific disease. The immune response produces protection from that disease. Effects from cancer and from treatments for cancer can reduce the body's natural disease fighting ability (called immunity). Factors such as vaccine type, timing of vaccine dosing related to treatment for cancer and number of vaccine doses or "boosts" (extra vaccine shots) may strengthen or diminish the body's protective immune response. This study may help researchers learn more about how the body's immune system responds to the COVID-19 vaccine when the vaccination is given during or after cancer treatment. Read Less

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

The purpose of this study is to evaluate the effectiveness of repurposed medications (study drug(s) in reducing symptoms of non-hospitalized participants with mild to moderate COVID-19. Participants will receive either study drug or placebo. Participants will self-report any new or worsening symptoms or medical events experienced while taking study drug or placebo. This study is intended to be all remote with no in person visits, unless the study team feels it is in the best interest of a participant to be seen in person. Prior and current drug arms are listed on clinicaltrials.gov and will be updated with the activation of any new drug arms. Each study arm will also have its own clinicaltrials.gov entry and will include "Pro00107921" in the Unique Protocol ID. Read Less

Hospitalized patients with severe COVID-19 have an increased incidence of insulin resistance, impaired beta cell function, glucose intolerance (prediabetes), and overt type 2 diabetes (T2D) compared to non-hospitalized patients with COVID-19 and COVID-19 negative individuals on long-term follow up.
