Active clinical trials for "COVID-19"

A randomised controlled trial of open label Prolectin-M; a (1-6)-alpha-D-Mannopyranose among patients with RT PCR positive COVID-19 patients.

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

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.

Phase Ib, open-label, multicenter, study of NOX66, given rectally to hospitalized patients with moderate systemic illness due to COVID-19 infection at high risk of developing severe sepsis / septic shock.

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

This is a phase 1b, open-label study in adult healthy subjects. This clinical trial is designed to assess the safety, reactogenicity, and immunogenicity of the hAd5-S-Fusion+N-ETSD vaccine and select a dose for future studies.

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

This is a Phase 1 randomized study to evaluate the safety, tolerability and efficacy of IV Ampion in improving the clinical course and outcomes of patients hospitalized with COVID-19 infection who require supplemental oxygen.

Stem cell therapy has emerged as a revolutionary treatment for diseases that were considered untreatable only a few years ago. Umbilical cord-derived mesenchymal stem cells (UCMSCs) have been shown to repair damaged liver, kidney, heart, pancreas, skin, cartilage, and cornea in animal models and several human trials. In addition to cellular replacement through regeneration, UCMSCs mediate through paracrine signaling pathways resulting in immune modulation. Clinical manifestations of coronavirus disease 2019 (COVID-19), are believed to arise from septic shock and cytokine storm that cause acute respiratory dysfunction and acute cardiac injury. There is presently no cure for the COVID-19 viral disease; however, multi-treatment strategies are being examined. During the past two months, four reports were published that suggest, mesenchymal stem cells (MSCs), owing to their powerful immunomodulatory ability, may prevent the cytokine storm and thus reduce the COVID-19 related morbidity. All studies reported that COVID-19 patients responded favorably to MSCs therapy. These reports, taken together with the previous successes of stem cell therapy in animal models, the investigators, a seven-institution consortium, propose to explore the efficacy of UCMSC treatment in COVID-19 patients at Jinnah hospital, Lahore. The investigators propose to administer UCMSCs in patients with acute pulmonary inflammation due to COVID-19 infection with moderate to severe symptoms. In the first cohort of 15 patients, UCMSCs will be administered with three intravenous infusions of 500,000 UCMSCs per Kg body weight each on days 1, 3, and 5. The second group of five patients serving as control will only receive standard treatment. During the 30-day post-infusion period, a battery of tests will be performed to evaluate the safety and efficacy of the UCMSCs treatment. In parallel, the investigators propose a comparative study to determine COVID-19 viral count by quantitative real-time PCR and through viral coat protein ELISA, developed in the investigator advisor lab (Dr. Tauseef Butt, Progenra Inc. Philadelphia, USA) with the ultimate objective to locally developing a rapid diagnostic assay.
