COVID19 Clinical Trials in San Antonio, TX

This is a prospective, phase 3, multicenter, double-blind, randomized placebo-controlled study to investigate the efficacy, safety, and pharmacokinetics (PK) of repeat doses of IgPro20 in participants with post SARS-CoV-2 infection 2019 postural orthostatic tachycardia syndrome (post-Coronavirus Disease 2019 \[COVID-19\] POTS \[post-COVID-POTS\]).

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

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 purpose of this trial is to assess the safety and relative efficacy of CVXGA (CVXGA50), a KP.2 containing vaccine, compared to COMIRNATY® (COVID-19 Vaccine, mRNA; 2024-2025 Formula), a currently approved COVID-19 vaccine in the prevention of symptomatic, RT-PCR-confirmed SARS-CoV-2 infection. The trial will enroll up to 10016 healthy participants. Read Less

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

This study is a platform protocol designed to be flexible so that it is suitable for a wide range of settings within health care systems and in community settings where it can be integrated into COVID-19 programs and subsequent treatment plans. This protocol is a prospective, multi-center, multi-arm, randomized, controlled platform trial evaluating various interventions for use in the treatment of autonomic dysfunction symptoms, including cardiovascular complications and postural orthostatic tachycardia syndrome (POTS), in PASC participants. The interventions tested will include non-pharmacologic care and pharmacologic therapies with study drugs. Read Less

Study VBT00001 is planned to be a Phase 1/2, randomized, modified double-blind, active-controlled, multi-center study to be conducted in approximately 980 adults aged 50 years and older in the United States. The purpose of the study is to assess the safety and immunogenicity of IIV-HD (high-dose inactivated influenza vaccine) + rC19 (adjuvanted recombinant COVID-19 vaccine) vaccine comprised of IIV-HD combined with different recombinant Spike (rS) antigen levels of rC19 compared to IIV-HD alone, rC19 (dose 1) alone, and IIV-HD and rC19 (dose 1) (coadministered in opposite arms). Placebo will be coadministered in the IIV-HD alone, rC19 (dose 1) alone, and IIV-HD + rC19 study groups to control for the number of injections and to maintain observer-blinding. Thus, each participant will receive two injections at enrollment, one in each deltoid muscle. Study details include: * The study duration will be approximately 12 months * Study intervention will be administered via a single intramuscular (IM) injection into the right and left deltoid muscles on D01 * Dose escalation with sequential enrollment (sentinel cohort followed by main cohort for a given dose) * The visit frequency will be D01, D09 (telephone call), D30, D182 (telephone call), and D366 (telephone call) Number of Participants: Approximately 980 participants are expected to be randomized.

The primary objective of the study is to determine the relative efficacy of the investigational oral severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) vaccine tablet VXA-CoV2-3.1 compared to a currently recommended vaccine for the prevention of symptomatic Coronavirus Disease 2019 (COVID-19).

The purpose of this clinical trial is to learn about how study medicine (Paxlovid, which contains nirmatrelvir and ritonavir) is changed and eliminated from the body, as well as its safety, and the extent to which side effects can be tolerated for treatment of pregnant women with mild or moderate COVID-19 compared to non-pregnant women with mild or moderate COVID-19. This study is seeking participants who: * are expecting a healthy baby and are in their second or third trimester pregnancy and have mild or moderate COVID-19 * are not pregnant and have mild or moderate COVID-19. All participants in this study will take Paxlovid by mouth every 12 hours for 5 days. We will study the experiences of people receiving the study medicine. This will help us decide if the study medicine is safe. All participants will take part in this study for at least 34 days; pregnant participants will take part until their delivery, so that the study duration may be up to 6 months, depending on their delivery date. During this time, participants will have 7to 8 visits and, if pregnant, a visit at delivery. Around 2 to 3 visits and the delivery visit will be done in person (at the clinic or at the participant's home). The other 5 visits may be done over the phone, unless in-person visit is necessary as decided by the doctor. Blood samples will be collected on the first 4 to 5 study visits (and at other study visits, if necessary). 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.

The research in this VA Merit will examine the effects of obesity and Post-COVID Conditions (PCC) on physical functioning, health-related quality of life, and adipose tissue inflammatory and cellular senescence profiles in older Veterans. Further, it will evaluate whether a weight loss intervention, including dietary modification and exercise, in obese Veterans with and without PCC will reduce systemic and adipose tissue inflammation and senescence and promote PCC recovery.
