Active clinical trials for "COVID-19"

The study is a randomized clinical trial to assess a natural formula of vanillin & wheat germ oil to treat and stop the clinical progression of COVID-19. The study aims to treat people with mild-to-moderate COVID-19 before their cases become severe. The study duration is a 5-day experimental intervention and an extended 4 weeks follow up.

The Covid pandemic has left us with a significant number of people suffering from Long COVID, which is a clinical diagnosis of significant and varying ongoing symptoms at least 12 weeks following COVID-19 infection and characterised frequently by fatigue and breathlessness. Acupuncture has been shown to help breathlessness and fatigue in other conditions including in patients with cancer. Cancer related fatigue in the largest study, was assessed by the multiple functional inventory (MFI) score, assessing 5 domains of health, to give a single score. We aim to randomise 160 patients, 80 in each arm. Randomisation and recruitment should take 24 months. Each patient will be offered 6 weeks of weekly acupuncture treatment with a structured questionnaire on wellbeing or no acupuncture with a structure questionnaire on well-being. Both groups of patients will be given continued general advice on management of their symptoms. The next point of involvement will be at 12 weeks which will also be the final visit unless patients in Arm B (Active Control) chose crossover to receive acupuncture. Data at this point will correspond to the end of the participants participation. Over the next 3 months data will be cleaned and analysed. The primary endpoint is General Fatigue scores, as self-reported by patients using the MFI, at 6 weeks. A 2-unit difference between groups (Acupuncture vs Active Control) in General Fatigue score is considered clinically important. The secondary endpoints will include differences in scores of various questionnaires and tests.

This is a prospective, randomized randomized immunologic study of response to influenza and SARS-CoV-2 vaccination across four of the US Influenza Vaccine Effectiveness (Flu VE) Network study sites.

Probiotic intervention has been currently suggested to provide supportive benefits in promoting health, including alleviating disease symptoms, protecting against diarrhea and respiratory infection, affecting growth and modulating the immune system by improving the beneficial gut microbiota colonization, giving direction on the gut-lung-axis pathway. This indicates that probiotics may become alternative to improve nutrition and reduce the risk of viral infections which may reduce the risk against Severe Acute Respiratory Syndrome Corona Virus-2 (SARS-CoV-2). Introduction to probiotics during adolescence can alleviate inflammation and invert dysbiosis. However, evidence on the effect of probiotic supplementation on enhancing antibody response to SARS COV-2 in adolescents is lacking. Moreover, previous studies showed the potential effect of probiotic supplementation to improve overweight and obesity in adolescents. A bi-directional relationship exists among nutrition, infection, and immunity as changes in one element will affect the others. The main objective of this study is to investigate the effect of dietary modulation of overweight and obese adolescent's gut microbiota through probiotic supplementation combined with healthy eating and physical activity counseling and psychosocial stimulation on nutritional status and antibody response to COVID-19 vaccination. This trial will conduct a 20-week intervention for overweight and obese adolescents.

This study will examine the effectiveness of a 6-week behavioral intervention for patients who are recently diagnosed with COVID-19. Patients and their households will be randomized to one of two groups (Standard of Care vs. Enhanced Standard of Care). Patients in the Standard-of-Care group will receive established clinical care and follow-up. Patients in the Enhanced Standard-of-Care group will receive standard-of-care plus tailored, real-time text messaging and virtual counseling delivered by promotores/as. We hypothesize that households in the Enhanced Standard-of-Care group will have fewer (any new) household COVID-19 infectivity rates compared to households in the standard-of-care group post-intervention.

Phase 2 clinical trial in adults previously vaccinated against SARS-CoV-2 in Chile with an initial schedule of two doses of CoronaVac® plus two booster doses with different vaccines. Subjects will randomly receive a third booster dose with Omicron, trivalent, or CoronaVac® vaccine. The humoral immunogenicity against COVID-19 will be compared in subjects that received the Omicron or the Trivalent vaccines with subjects that received CoronaVac® to determine the superiority of the two candidate vaccines versus CoronaVac®. Subjects will be followed for 6 months after the booster dose administration.

Observer-blind, randomized, active-controlled prospective intervention study of Immunogenicity & Safety of SARS-Cov-2 Protein Subunit Recombinant Vaccine (Bio Farma) as a Booster Dose Against COVID-19 in Adults 18 Years of Age and Older.

This is a proof-of-concept double-blind cluster randomized (1:1) parallel study. The randomization unit is healthy volunteers who have no symptoms of COVID-19 at the start of the study and have not been infected with the SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) virus in the past 90 days. The selected individuals are randomly grouped in either the experimental group (individuals using the BioBlock® antiviral nasal spray immediately after waking up in the morning and thereafter once every 4 hours and so for 28 days) or the control group (placebo is used by individuals immediately after waking up in the morning and thereafter once every 4 hours and so for 28 days).

The "Social network diffusion of COVID-19 prevention for diverse Criminal Legal Involved Communities" study will engage people who have been interacted with law enforcement in COVID-19 prevention (testing and/or vaccination) through social network mobilization combined with theory-driven COVID-19 prevention messaging delivered in an interactive group format. Eligible individuals will be enrolled into a two-arm 1:1 randomized controlled trial design. 800 participants will be enrolled into either a: 1) COVID-19 prevention education arm (Education Arm) or, 2) a network mobilization change agent intervention (Motivational Arm).

This clinical trial aimed to gather safety and immunogenicity data in COVID-19 vaccine-experienced healthy adults. The main questions it aims to answer are: The neutralizing antibodies levels of bivalent mRNA vaccines RQ3027(Alpha/Beta+Omicron XBB.1.5) and RQ3025(Alpha/Beta+Omicron BA.2/4/5) and monovalent mRNA vaccine RQ3013 against the current SARS-CoV-2 circulating variant. The safety profile of RQ3027 and RQ3025 given as a second booster dose to COVID-19 vaccine-experienced participants 18 through 55 years of age. Explore the protective efficacy by documenting confirmed COVID-19 cases after vaccination.
