Active clinical trials for "COVID-19"

In COVID-19 infection caused by the Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), there is a dysregulation of the immune system response that causes cytokine storm syndrome. SARS-CoV-2 works like a hijacker (hackers), sabotaging communication between cells so that the immune system, like T-cells, kills not only infected cells but also healthy cells. This dysregulation results in hyper-inflammation which cause damage to organs, not just the lungs. This is the cause of the high mortality rate in COVID-19 patients. Exosomes are vesicles with a size of 30-100 nanometers originating from within cells that function to communicate with other cells. Exosomes are transport containers that contain bioactive cargo: such as proteins, genetic material, and various other molecules. These containers move from cells of origin, flowing through blood vessels or other body fluids to target cells. Exosomes penetrate the cell membrane and act on various organelles within the target cell. All cell types can produce exosomes. What differentiates them is the cargo they contain. The exosome produced by mesenchymal stem cells (MSCs) contains bioactive cargo derived from mesenchymal stem cells, such as anti-inflammatory cytokines, growth factors, messengerRNA (mRNA) and microRNA (miRNA). The target cells are immune system cells, infected cells and progenitor cells from infected organs. On target immune cells, the anti-inflammatory cytokines work as immunomodulators to relieve hyper-inflammation. In infected cells, the miRNAs work to prevent viral replication by inhibiting the expression of SARS-CoV-2 virus RNA (viral mRNA silencing and degrading). In lung progenitor cells and other infected organs, the growth factors work to stimulate protein synthesis processes that function for organ regeneration. This study is a multi-center, double-blind, randomized controlled trial (RCT) clinical trial with two arms: one intervention arm, and one control arm. The EXOSOME-MSC will be tested as adjuvant, on top of standard COVID-19 drugs. It will be injected to participants via intravenous route twice, in day-1 and day-7 of 14 days of study participation.

The purpose of this study is to evaluate the safety, tolerability and preliminary efficacy of EOM613, a peptide nucleic acid with novel immune-modulating properties, in treating patients with severe COVID-19 infections. This proof-of-concept study is the first clinical trial of EOM613 in this patient population.

This study will evaluate the safety of administering an additional dose of an mRNA COVID-19 vaccine or mRNA bivalent COVID-19 booster vaccine to individuals who have had adverse reactions to a previous dose or administering an initial dose of an mRNA COVID-19 vaccine to individuals with a personal history of allergic reaction. In addition, this study will evaluate the safety of administering an initial or additional dose or bivalent booster of an mRNA COVID-19 vaccine to individuals experiencing an adverse reaction to a natural COVID-19 infection ("long COVID"). Eligible participants enrolled in this trial will receive an initial or additional dose of either the Pfizer-BioNTech COVID-19 bivalent vaccine or the Moderna COVID-19 bivalent vaccine. Participants will also be required to have 1-2 in person visits along with phone call follow up visits. We hypothesize that individuals who have had adverse reactions to a previous dose of an mRNA COVID-19 vaccine will tolerate an additional dose of the primary mRNA vaccine or bivalent booster, as indicated, and those with a personal history of allergic reaction will tolerate an initial dose of an mRNA COVID-19 vaccine. We also hypothesize that those individuals experiencing an adverse reaction will tolerate an initial or additional dose of a primary mRNA COVID-19 bivalent vaccine, as indicated. The study hypothesizes that individuals that have had adverse reactions to a dose of an mRNA COVID-19 vaccine will tolerate an additional dose and those with a personal history of allergic reaction will tolerate vaccination with an mRNA COVID-19 vaccine.

Healthcare workers and COVID-19 patients may experience psychological distress consequent to the pandemic, and are at particularly elevated risk for experiencing posttraumatic stress disorder (PTSD), based on evidence from previous infectious disease outbreaks. The best-validated treatment for PTSD is exposure therapy. Exposure therapy help patients suffering from PTSD to revisit and overcome their traumatic experiences. Including virtual reality in exposure therapy has a long history in treating PTSD; and has been used to treat military veterans and first-responders following 9/11. The investigators are developing and testing a virtual reality platform to be used in treating healthcare workers and COVID-19 patients who develop PTSD resulting from their experiences in the COVID-19 pandemic. Participants will complete ten ninety minute sessions, twice a week for five weeks aimed at mitigating their symptoms of PTSD. The pilot study will aim to demonstrate the feasibility and the tolerability of the virtual reality intervention in these populations.

The 2019 Severe Acute Respiratory Syndrome (SARS) is a global pandemic secondary to a novel coronavirus - SARS-CoV-2. The reported case-fatality ratio for SARS-CoV-2 in the United States is 1.8% with a current death toll of >300,000 and climbing.4 There is no accepted standard of care or FDA approved therapies for treatment of COVID-19. Virus specific cytotoxic T lymphocytes (CTLs) have become an important part of the treatment landscape for viral reactivation post hematopoietic and solid organ transplantation. Donor derived CTLs have been shown to be safe and effective against a variety of viruses including CMV, EBV, BK and adenovirus. We hypothesize that SARS-CoV-2 specific CTLs generated from a previously infected family donor will be safe and effective for treatment of COVID-19 in family members with mild to moderate disease.

The sequelae that occur in post-COVID-19 patients are multiple and, at a therapeutic level, these represent a new challenge within the general context of the pandemic that the world is suffering. The virus has managed to end thousands of lives today and many other cases are being charged as directly responsible for a multiplicity of multi-system damages that need to be diagnosed and treated. Among the most relevant, are those that can affect to neurological, respiratory and musculoskeletal levels in patients without previous pahologies, and in patients at risk who already had a pathology prior to infection. On the other hand, signs and symptoms have been observed characteristic in the organ systems described above in post-contagion patients, directly associated with sequelae SARV-CoV2. The radio frequency (RF) of electromagnetic waves represents a technology of proven efficacy and safety in multiple fields of both human and veterinary medicine. These include neurological and pneumological pathologies, and very especially those that affect the locomotor system. In therapeutics there are different RF modalities depending on the modality, polarity, type of signal and frequency, which in turn translate into different therapeutic profiles, clinical indications, efficacy and safety. Among the RF technologies most used today and that have a greater scientific background, is the one known as Resistive Capacitive Monopolar Radio Frequency at 448 kHz (INDIBA®) (RFMCR). This study aims to assess the efficacy and safety of RFMCR in the treatment of neurological, respiratory and musculoskeletal sequelae in patients presenting this type of pathologies that appear after contagion by COVID-19. Through this non-invasive technique, the investigators want to show that RF can help the physical rehabilitation of these patients through metabolic stimulation, increased vascularization and oxygenation of directly affected tissues, effects of deep hyperthermia generated by the interaction of the current with the treated biological substrate, as well as the activation of tissue regeneration, the result of subthermal action. It is thus intended to improve signs such as lung capacity, dyspnea, neuropathies and global muscle capacity, which are essential for the recovery of the post-COVID-19 patients. The hypothesis of this study is that current post-COVID-19 treatments can be significantly improved in order to prevent complications and ensure the patients' well-being.

This is a phase I trial followed by a phase II randomized trial. The purpose of phase I study is the feasibility of treating patients with acute respiratory distress syndrome (ARDS) related to COVID-19 infection (COVID-19) with cord blood-derived mesenchymal stem cells (MSC). The purpose of the phase II trial is to compare the effect of MSC with standard of care in these patients. MSCs are a type of stem cells that can be taken from umbilical cord blood and grown into many different cell types that can be used to treat cancer and other diseases. The MSCs being used for infusion in this trial are collected from healthy, unrelated donors and are stored and grown in a laboratory. Giving MSC infusions may help control the symptoms of COVID-19 related ARDS.

Background: People who are recovering from COVID-19 may continue to have problems that affect their daily life. For instance, they might feel overly tired. Researchers want to learn if exercise can help people recover after COVID-19 infection. Objective: To study if participation in a rehabilitation exercise program can help people recovering from COVID-19. Eligibility: Adults ages 18-80 with a lab-confirmed SARS-CoV2 infection (the virus that causes COVID-19), and are still having some symptoms. Design: Participants will have a medical history and physical exam. They will give blood and urine samples. They will have tests to measure heart and lung function. Their blood vessels will be assessed. Participants will have a computed tomography scan of the body. They will have an ultrasound of the muscles in their arms, legs, and chest. Participants will take a 6-minute walk test. They will take other balance and movement tests. Participants will walk on a treadmill while hooked up to a monitor. Then they will be interviewed. It will be audio-recorded. Participants will complete surveys about their symptoms and daily activities. Participants will take a smell test. For this, they will identify different smells. They will also have memory, attention, and mental functioning tests. Participants will wear an activity monitor on their wrist 24 hours a day. They will exercise 3 times a week for 10 weeks by moving vigorously on a track or treadmill for 30 minutes. They will attend education classes once a week for 10 weeks. Participants will be contacted by phone or email every 3 months for 1 year after they complete the exercise part of the study. They will wear an activity monitor for up to 2 weeks.
