Active clinical trials for "COVID-19"

Randomized, placebo-controlled study to evaluate the safety, pharmacokinetics and efficacy of a single dose of STI-1499 (COVI-GUARD™) in hospitalized patients with moderate COVID-19

The investigators aim to evaluate the efficacy of pre-exposure prophylaxis with hydroxychloroquine in healthcare workers with high-risk of SARS-CoV-2 infection.

COVID-19 virus remains in infected patients for extended periods of time. A great resource burden is placed on the healthcare system and society at large to isolate COVID-19 patients for prolonged periods. Thus, being able to increase the rate of viral clearance, thus reducing the duration of COVID-19 infection, would allow patients to be discharged earlier to free up resources for those who require it. The investigators designed a randomized controlled trial, investigating the use of Lianhua Qingwen, a TCM treatment, in COVID-19 infected patients with mild symptoms. The investigators hypothesize that the use of Lianhua Qingwen will increase the proportion of patients who test negative for COVID-19 after 8 days of TCM treatment when compared to the group of patients provided with standard care and placebo. Patients will be recruited from community isolation facilities, and have onset of symptoms within 5 days prior to admission to the isolation facility. The trial also evaluates the time taken for relief of clinical symptoms associated with COVID-19 and assesses the safety of the TCM treatment given to patients.

The aim is to demonstrate a decrease in complications among ambulatory patients who are diagnosed with mild COVID-19 by treating them with nitazoxanide for 7 to 14 days on top of standard care compared to patients who receive standard care and placebo only.

The current sars-cov-2 epidemic is responsible for severe respiratory infections leading to end-of-life situations. Dexmedetomidine may be indicated in mild to moderate sedation in palliative patients, due to its pharmacological characteristics. The hypothesis of this study is that Dexmedetomidine would allow effective and safe light sedation in patients with respiratory failure in palliative situations suffering from Covid-19 infection.

Patients over equal or older than 65 yearswill be treated with a hydroxychloroquine versus placebo reduced loading dose of 600mg on the first day followed with 400mg/day divided in 2x200mg for 6 more days resulting in a total duration of therapy of 7 days. Measurement of Hydroxychloroquine-levels will be performed on day 7, . A follow-up by video or telephone conference will be performed to observe drug intake and collect adverse events during treatment phase on a daily base on working days and once during the weekend (i.e. 6 out of 7 days). After treatment phase follow-up by telephone calls will be done on day 10, 30, 60 (+/- 2 days).

This study is being done to see if hydroxychloroquine is an effective treatment for COVID-19.

Double blind, Multi-Centre study to evaluate the safety, reactogenicity, tolerability, and immunogenicity of three investigational vaccine groups and one placebo group in healthy volunteers who receive two intramuscular doses of BBV152 vaccine formulations and placebo. A total sample size of 755 healthy volunteers, with 375 and 380 volunteers in phase 1 and 2 studies, respectively. A protocol amendment was made to evaluate a boosting regimen at the 6-month interval in the Phase 2 trial. At 6 months post-dose 2, participants who received the 6ug Algel-IMDG allocation were randomized equally to receive a third dose of BBV152 (6ug Algel-IMDG) or placebo.

This study seeks to determine whether dual or quadruple therapy is more effective in treating COVID-19.

The purpose of this research study is to evaluate and improve a rapid COVID-19 test. The test is designed to identify people who are most contagious and likely to spread the virus to others. This test will be performed at various locations in the Madison area using a mobile laboratory or standard lab space for processing. Saliva samples can be collected and processed at these locations or participants can self-collect at home and drop their samples off at designated locations for same day processing. Results of potential findings of clinical significance will be communicated to the participants by a physician with appropriate expertise on the study team. Individuals with a potential finding of clinical significance will be encouraged to self-isolate and obtain a diagnostic test at their earliest convenience. No results will be given if the test is negative. If the participant consents, advanced molecular testing such as PCR or viral sequencing can be done and results can be shared via online databases, presentations and publications along with the date, site and county of collection to help facilitate tracking the spread of the virus.
