COVID19 Clinical Trials in Los Angeles, CA

The purpose of the study is to evaluate whether ibuzatrelvir is effective and safe in adults and adolescents with COVID-19 who do not need to be in the hospital but who are at high risk for progression to severe disease. Eligible participants will be randomly assigned (by chance) to receive ibuzatrelvir or matching placebo orally for 5 days. Co-administration of locally available standard of care is allowed. The total duration of the study is around 6 months. 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

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.

This is a pilot randomized trial of rTMS for symptoms of fatigue and brain fog, and other neuropsychiatric symptoms of Long-COVID (Post-COVID, post-acute sequelae of COVID-19 infection, PASC). Twenty participants diagnosed with Long-COVID and recruited from the UCLA Long-COVID clinic will be randomized to receive active rTMS versus sham stimulation for 15 treatments followed by another 15 open-label rTMS treatments. Investigators will compare the safety and tolerability of rTMS vs Sham and examine within-group changes in symptoms of fatigue, sleep, pain, mood, and subjective and objective cognitive impairment. This project will provide information and pilot data for future larger clinical trials. 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

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

The purpose of this clinical trial is to learn about the safety, pharmacokinetics (pharmacokinetics helps us understand how the drug is changed and eliminated from your body after you take it), and efficacy (how well a study treatment works in the study) of the study medicine (called nirmatrelvir/ritonavir) for potential treatment of coronavirus disease 2019 (COVID-19). The study medicine will be given to patients under 18 years of age with COVID-19 that are not hospitalized but are at risk for severe disease. Read Less

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

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 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.

Rationale: Hyper-inflammatory responses seen in acute COVID-19 are also a feature of long covid, a condition of long-term consequences that are persisting or appearing after initial infection and recovery from acute COVID-19. Long-standing, often disabling symptoms are common in long covid and can be highly varied. Common symptoms include fatigue, brain fog, muscle and chest pain, migraines, shortness of breath, anosmia, muscle weakness, and cognitive dysfunction. 35% of post-COVID patients were found to have decreased kidney function at 6 months post-discharge. In this study, we will evaluate the effect of dietary interventions in long covid patients. The dietary interventions are aimed at lowering blood glucose levels, and raising blood BHB levels. The dietary plan will recommend a low-carbohydrate diet including the avoidance of foods containing sugars and starch, while simultaneously increasing the consumption of healthy fats and sources of protein. The dietary interventions are supported by the consumption of a medical food that delivers exogenous BHB in order to raise blood BHB levels without the necessity of adhering to a strict ketogenic diet which would be difficult to implement and typically requires strict medical supervision. Intervention: Dietary intervention with Ketocitra versus control arm (no intervention) in a 1:1 ratio Objectives: The hypothesis of this study is that low-carbohydrate dietary interventions leading to lowering of blood glucose and raising of blood BHB in addition to standard therapy will lead to faster recovery and amelioration of symptoms in long covid compared to those treated with standard therapy alone. Study population: Subjects with a history of COVID-19 at least 2 months ago and with at least 2 neurological and/or symptoms that are typical for long covid that either started at COVID-19 infection and are ongoing at time of study entry Study methodology: Prospective and interventional randomized controlled pilot study Study arms: Dietary intervention (including medical food) arm versus control arm Study endpoints: The primary endpoint is the feasibility, safety and tolerability of dietary intervention.
