COVID19 Clinical Trials in Sacramento, CA

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

This study will seek to enroll immunocompromised patients with Lower Tract parainfluenza infection. It also contains a sub-study to enroll patients with severe COVID-19. Read Less

Immunocompromised individuals, such as solid organ transplant (SOT) recipients are at high risk of COVID-19 associated complications and mortality. Retrospective studies so far have shown that a majority of SOT recipients did not develop appreciable anti-spike antibody response after a first, second, or even third dose of mRNA vaccine. Treatment with antimetabolites was associated with poor vaccine response. The goal of this study is 1) examine whether transient immunosuppression reduction improves the immune response to a third dose of SARS-CoV-2 mRNA vaccine in kidney transplant recipients and 2) to assess the safety of immunosuppression reduction before and after third dose SARS-CoV-2 mRNA vaccination.
