The objective of our study is to evaluate safety, tolerability, and immunogenicity ofCOVID-19 preventive DNA vaccine in healthy volunteers.

This Phase 2 Randomized Placebo Controlled Trial will determine if administeringnebulized Dornase Alpha (rhDNase) to COVID-19 patients with respiratory failure is safeand will reduce 28-day mortality.

This is a randomised placebo controlled phase II trial to examine the efficacy ofantivirals to treat COVID-19 infection compared to placebo for virological cure andimproved clinical outcomes. Individuals will be randomised to the candidate antiviralwhich in the first instance is Favipiravir or matched placebo and randomisation will bestratified according to whether the participant requires hospitalisation or not. Thistreatment will be given in addition to the usual standard of care in the participatinghospital.

The purpose of this study is to evaluate how useful vitamin D supplementation is inreducing the severity of COVID-19 symptoms and the body's inflammatory andinfection-fighting response to COVID-19. Individuals ≥50 years of age and older who aretested for COVID-19 and negative will be randomized (like flipping a coin) to eitherdaily high dose vitamin D supplementation (6000 IU vitamin D3/day) vs. standard of care.Those individuals ≥50 years of age or older who test positive for COVID-19 at baselinewill be randomized to bolus vitamin D (20,000 IU/day for 3 days) followed by high dose(6000 IU vitamin D/day) vs. standard of care for 12 months. All participants will receivea multivitamin containing vitamin D.

This is a randomized, double-blinded, placebo-controlled, two-arm study to evaluate thesafety and efficacy of BIO 300 Oral Suspension (BIO 300) as a therapy to improve lungfunction in patients that were hospitalized for severe COVID-19-related illness andcontinue to experience post-acute respiratory complications associated with Long-COVIDafter discharge. Patients will be randomized 1:1 to receive BIO 300 or placebo.

Ultomiris (Ravulizumab), is a monoclonal antibody that specifically targets terminalcomplement products and is proposed for the treatment of COVID-19 inducedmicrovasculature injury and endothelial damage leading to thrombotic microangiopathy(TMA) causing acute kidney injury (AKI). Ravulizumab is to be used for participants witha confirmed diagnosis of COVID-19 who clinically or diagnostically present withdeteriorating renal function. Ravulizumab causes immediate and sustained inhibition ofthe terminal complement cascade. The use of ravulizumab could ameliorate COVID-19 inducedkidney injury due to TMA, shorten hospital stay, and improve the overall survival.

Patients suffering lung failure, possibly from COVID-19 or hypoxic lung failure, willneed life-saving support from a breathing machine. Any patient needing this supportrequires drugs to keep them sleepy, or "sedated" to be comfortable on this machine.Sedation is made possible by using drugs given through a vein. Unfortunately, these drugsare in short supply worldwide due to the high number of COVID-19 patients needing thesemachines.Another way to provide sleep is by using gases that are breathed in. These are used everyday in operating rooms to perform surgery. These gases, also called "inhaled agents" canalso be used in intensive care units and may have several important benefits for patientsand the hospital. Research shows they may reduce swelling in the lung and increase oxygenlevels, which allows patients to recover faster and reduce the time spent on a breathingmachine. In turn, this allows the breathing machine to be used again for the next sickpatient. These drugs may also increase the number of patients who live through theirillness. Inhaled agents are widely available and their use could dramatically lesson thepressure on limited drug supplies.This research is a study being carried out in a number of hospitals that will compare howwell patients recover from these illnesses depending on which type of sedation drug theyreceive. The plan is to evaluate the number who survive, their time spent on a breathingmachine and time in the hospital. This study may show immediate benefits and may providea cost effective and practical solution to the current challenges caring for patients andthe hospital space, equipment and drugs to the greatest benefit. Furthermore, the studywill be investigating inflammatory profile and neuro-cognitive profiles in ventilatedpatients. Finally, this trial will be a team of experts in sedation drugs who care forpatients with proven or suspected COVID-19 who need lifesaving treatments.

Primary Objective:To determine the maximum tolerated dose (MTD) of SAR442257 administered as a single agentin patients with relapsed and refractory multiple myeloma (RRMM) and relapsed andrefractory non-Hodgkin lymphoma (RR-NHL), and determine the recommended Phase 2 dose(RP2D)Secondary Objectives: - To characterize the safety profile of SAR442257 - To characterize the pharmacokinetics (PK) profile of SAR442257 - To assess preliminary evidence of antitumor activity

This is a pivotal phase III study to evaluate the efficacy of nitazoxanide 600 mg BIDcompared to placebo to treat hospitalized patients with non-critical COVID-19.

Thymalfasin (thymosin alpha 1 or Ta1), the active pharmaceutical ingredient in ZADAXIN®injection, is a 28-amino acid synthetic peptide, identical to natural Ta1 produced by thethymus gland. Ta1 is a biological response modifier which activates various cells of theimmune system, and is therefore expected to have clinical benefits in disorders whereimmune responses are impaired or ineffective, including acute and chronic viral andbacterial infections, cancers, and vaccine non-responsiveness. Patients with end-stagerenal disease (ESRD) on hemodialysis, in addition to their intrinsic kidney disease andfrequent burden of comorbidities, also have increased risk of exposure to communicablediseases as they are treated several times each week at hemodialysis centers with severalother patients and clinic staff in attendance. The majority of patients are over 60 yearsof age and many are receiving immunosuppressive medications. Accordingly, ESRD patientsare particularly susceptible to COVID-19 infection. Ta1 has been shown to be safelyadministered to hemodialysis patients. It is our hypothesis that a course of Ta1administered to individuals with ESRD will reduce the rate and severity of infection withCOVID-19.
