Active clinical trials for "COVID-19"

Up to 1/3 of all patients infected with COVID-19 can develop complications that require hospitalization. Severe pneumonia associated with acute respiratory distress syndrome (ARDS) is the most threatening and feared complication of COVID-19 infection, with mortality rates close to 50% in some groups. Autopsies between these severe cases reveal severe capillary involvement, with signs of intense inflammatory changes, microvascular thrombosis, endothelial injury and abnormal tissue repair. The available evidence suggests that abnormal activation or imbalance in the counter-regulation of the kallikrein-kinin system may play a central role in a positive feedback cycle, leading to consequent diffuse microangiopathy. Blockade of the kallikrein-kinin system can therefore prevent deterioration of lung function by reducing inflammation, edema and microthrombosis. The objective of this phase IIb study is to assess the preliminary effects on the oxygenation parameters of an antisense oligonucleotide that inhibits pre-kallikrein synthesis in patients with moderate to severe COVID-19.

Evaluate the safety pharmacokinetics and pharmacodynamics (PK/PD)of a single dose of Kamada anti-severe acute respiratory syndrome (SARS)- CoV-2 in patients hospitalized with COVID-19 caused pneumonia

The emergence of asymptomatic patients poses a significant challenge to the prevention and treatment of the epidemic.There have not been any treatment options that reduce the viral load or preventive options that reduce the risk of developing severe conditions.Therefore, present feasibility study of the safety and efficacy of Guduchi Ghan Vati was conducted in asymptomatic patients with COVID-19

In recent months severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) has emerged as a novel human pathogen and, susceptibility amongst humans is presumed to be universal. Prevention measures of COVID-19 have included distancing, quarantines, use of facemasks in public places, and hand hygiene measures. Mandatory quarantines have also been applied on index cases and their contacts, as well as an active search for asymptomatic patients. Current strategies to reduce the spread of SARS-CoV-2 do not include measures that could prevent transmission prior to the onset of symptoms. Subjects infected with SARS-CoV-2 have been known to shed virus and be contagious for up to 5 days prior to developing symptoms ('pre-symptomatic transmission'). In fact, nearly 60% of all infected subjects can shed virus pre-symptomatically. Pre- or even asymptomatic shedding occurs across all age groups, contributing to the rapidly expanding pandemic. Post-exposure prophylaxis (PEP) using type 1 interferon (IFN) can potentially eliminate the spread of SARS-CoV-2. IFN could reduce the period of viral shedding by ~1 week. Since pre-symptomatic shedding of virus can start up to 5 days prior to symptom onset, our approach of a PEP intervention to all contacts recently exposed to a case could possibly entirely interrupt the spread of the virus, and with that, the pandemic. The current study focuses on prevention of the disease in addition to its treatment. Thus, the key distinction between these other trials and this study is that this study focuses on containing coronavirus (i.e. cause) in the community, rather than simply its treatment (i.e. consequence) in the individual. Viral spread could be eliminated through interventions effective at abolishing viral transmission. However, such post-exposure prophylaxis interventions, that is initiation of antiviral therapy in pre-infectious contacts to reduce or even eliminate such spread, must be safe since they are given to asymptomatic and possibly uninfected subjects. In none of the previous clinical trials of IFN therapy for SARS-CoV-2 have serious adverse events been recorded. Furthermore, the IFN chosen for this study (pegylated IFN 1b) has been extensively studied in clinical trials, and has been in clinical use for years for multiple sclerosis. Pegylated IFN formulations allow for weekly injections while maintaining serum levels and limiting dose-dependent side effects. Together these data support a sound safety profile for the planned intervention. The aim of this study is to ascertain whether IFN administered to index cases and household contacts of an index case, starting immediately following confirmed exposure (index case confirmed positive for SARS-CoV-2), will reduce duration of SARS-CoV-2 detectable by PCR in the index cases, and incidence of SARS-CoV-2 detectable by PCR in household contacts.

A multi-center adaptive randomized placebo-controlled platform trial evaluating the efficacy and safety of anti-thrombotic strategies in COVID-19 adults not requiring hospitalization at time of diagnosis

Background: COVID-19 is a new disease caused by SARS-CoV-2 that was identified in 2019. Some people who get sick with COVID-19 become ill requiring hospitalization. There are some medicines that may help with recovery. Researchers want to see if a drug called fostamatinib may help people who are hospitalized with COVID-19. Objective: To learn if fostamatinib is safe in patients who are hospitalized with COVID-19 and gain earlier insight into whether it improves outcomes. Eligibility: Adults age 18 and older who are hospitalized with COVID-19. Design: Participants will be screened with a physical exam, including vital signs and weight. They will have a blood test and chest x-ray. They will have a COVID-19 test as a swab of either the back of the throat or the back of the nose. They will take a pregnancy test if needed. Participants will be randomly assigned, to take either fostamatinib pills or a placebo twice daily for up to 14 days in addition to standard of care for COVID-19. If they can swallow, they will take the pills by mouth with water. If they cannot swallow or are on mechanical ventilation, the pills will be crushed, mixed with water, and given through a tube placed through the nostril, or placed in the mouth, down the esophagus, and into the stomach. Blood samples will be taken daily. Participants will return to the Clinical Center for safety follow-up visits. At these visits, they will have a physical exam and blood tests. If they cannot visit the Clinical Center, they will be contacted by phone or have a telehealth visit. Participation will last for about two months

Background - A novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was first identified in December 2019 as the cause of a respiratory illness COVID-19 in Wuhan City, China. WHO declared a public health emergency outbreak of this virus on 30 January 2020 and declared COVID-19 a global pandemic on 11 March, 2020. Bangladesh reported its first case on March 8, 2020 and first fatality on April 1, 2020. Bangladesh had shown a staggered course of COVID-19 transmission initially but a surge in cases was observed from April, 2020. Remdesivir remains as the only potential therapy for the treatment of COVID-19 till date. Based on several pre-clinical studies in SARS-CoV and MERS-CoV infections, Animal trials in COVID-19 and data from human trials, this randomized, controlled, open label trial will evaluate the antiviral activity and safety of Remdesivir in Bangladeshi hospitalized patients with severe COVID-19. This study finding will provide knowledge if Remdesivir is effective enough to treat Bangladeshi COVID-19 hospitalized patients with adequate safety and tolerability. The result of this study will help the key opinion leaders regarding the matter, to take appropriate decision regarding usage of Remdesivir for the treatment of COVID-19 in Bangladesh. Study Procedure - All patients will receive the standard medical care for COVID-19+ve at the respective hospitals. Vital signs will be recorded every 24 hrs for 1st 5 days then once in 2 days till discharge or as per the discretion of the attending physicians. After screening the COVID-19 confirmed patients will be randomized into 2 treatment arms. Patient's safety assessment e. g. blood parameters (CBC, Creatinine, SGPT, RBS, Creatinine, Creatinine Clearance) will be done on screening, day 5 and day 14 or discharge; Chest X-ray and ECG on screening and day 14 or discharge. SARS-CoV-2 (viral load) will be looked in on day 5, day 10 and day 14 or at the time of discharge. In case any study patient deteriorates during the study period will be managed as per the guideline of that particular hospital and if needed will be shifted to ICU. Patients who will recover will be discharged as per the national guideline for the COVID-19 hospitalized patients. Patients will be contacted at 28 days either over phone or in person to get their health status since discharge.
