Active clinical trials for "COVID-19"

Convalescent Plasma for COVID-19 Research (CONCOR-Donor) study, is a national, natural history study of plasma donors recovered from COVID-19. CONCOR-Donor study will address immune response, duration of protective immunity, and clinical factors and host genetics contributing to the variability of immune response. We will also study long-term outcomes from COVID-19 infection. Results from the study will help define therapeutic strategies for COVID-19.

The first-in-human Phase 1 study component will evaluate two dose levels of RAPA-501-ALLO off the shelf cells in patients with COVID-19-related ARDS, with key endpoints of safety, biologic and potential disease-modifying effects. The randomized, double-blind, placebo-controlled Phase 2b study component will evaluate infusion of RAPA-501 ALLO off the shelf cells or a control infusion, with the primary endpoint assessing whether RAPA-501 cells reduce 30-day mortality. The COVID-19 pandemic is a disaster playing out with progressive morbidity and mortality. As of April 6th, 2021, an estimated 132.1 million people have contracted the virus and 2,866,000 deaths have resulted globally. The United States has the highest totals with an estimated 30.8 million people diagnosed and 556,000 deaths. In stages 1 and 2 of COVID-19, viral propagation within the patient is predominant. As such, therapeutic interventions focus on immune molecules (convalescent serum, monoclonal antibodies) and anti-viral medications (remdesivir). In marked contrast, the most severe and deadly form of COVID-19, stage 3, is driven not by viral propagation, but by an out-of-control immune response (hyperinflammation) caused by increases in immune molecules known as cytokines and chemokines. As such, therapeutic interventions for stage 3 disease focus on anti-inflammatory medications such as anti-cytokine therapy (anti-IL-6 drugs) or corticosteroid therapy. Unfortunately, such interventions do not address the full pathogenesis of stage 3 COVID-19, which includes hyperinflammation due to "cytokine storm" and "chemokine storm," tissue damage, hypercoagulation, and multi-organ failure (including lung, heart, kidney and brain). The pulmonary component of stage 3 disease includes acute respiratory distress syndrome (ARDS), which is a final-common-pathway of patient death due to a myriad of conditions, including pneumonia, sepsis, and trauma. There is a dire need for novel cellular treatments that can deliver both a broad-based immune modulation effect and a tissue regenerative effect, such as RAPA-501-ALLO off-the-shelf allogeneic hybrid TREG/Th2 Cells. Stage 3 COVID-19 carries an estimated 30-day mortality of over 50% in spite of ICU utilization, mechanical ventilation, and supportive care therapies to manage ARDS and multiorgan failure. Narrowly acting targeted anti-inflammatory approaches such as anti-IL-6 therapeutics have not been particularly effective in stage 3 COVID-19 and the broad anti-inflammatory pharmaceutical approach of corticosteroid therapy, has only modestly tempered stage 3 disease in some studies. Cell therapy is also being evaluated in stage 3 COVID-19, in particular, mesenchymal stromal cells (MSC) and now, with the current RAPA-501-ALLO protocol, regulatory T (TREG) cells. TREG therapy has a mechanism of action that includes a multi-faceted anti-inflammatory effect, which puts TREG therapy at the forefront of future curative therapy of a wide range of autoimmune and neurodegenerative diseases, plus transplant complications, such as graft-versus-host disease (GVHD) and graft rejection. In addition, TREG therapy can provide a tissue regenerative effect, which places TREG cell therapy at the lead of novel regenerative medicine efforts to repair a myriad of tissue-based diseases, such as diseases of the skin, muscle, lung, liver, intestine, heart (myocardial infarction) and brain (stroke). RAPA-501-ALLO off-the-shelf cell therapy offers this potential dual threat mechanism of action that incorporates both anti-inflammatory and tissue repair effects for effective treatment of COVID-19 and multiple lethal conditions. RAPA-501-ALLO cells are generated from healthy volunteers, cryopreserved, banked, and are then available for off-the-shelf therapy anytime. During manufacturing, T cells are "reprogrammed" ex vivo using a novel, patented 7-day two-step process that involves T cell de-differentiation and subsequent re-differentiation towards the two key anti-inflammatory programs, the TREG and Th2 pathways, thus creating a "hybrid" product. The hybrid phenotype inhibits inflammatory pathways operational in COVID-19, including modulation of multiple cytokines and chemokines, which attract inflammatory cells into tissue for initiation of multi-organ damage. The hybrid TREG and Th2 phenotype of RAPA-501-ALLO cells cross-regulates Th1 and Th17 populations that initiate hyperinflammation of COVID-19. RAPA-501 immune modulation occurs in a T cell receptor independent manner, thus permitting off-the-shelf cell therapy. Finally, in experimental models of viral pneumonia and ARDS, TREG cells mediate a protective effect on the lung alveolar tissue. Because of this unique mechanism of action that involves both anti-inflammatory and tissue protective effects, the allogeneic RAPA-501 T cell product is particularly suited for evaluation in the setting of COVID-19-related ARDS.

COVID-19 is a disease with high rate of morbidity if symptomatic. There is a great need of treatments to decrease the severity. The vast majority of patients needing intensive care are men, and this may be due to the androgens, either by regulation of TMPRSS2, necessary for virus internalization, or other mechanisms. Enzalutamide is an antiandrogen inhibiting the expression of androgen regulated proteins, such as TMPRSS2. The aim of this trial is to evaluate a possible beneficial effect of short-term enzalutamide treatment of COVID-19 patients.

The purpose of this study is to evaluate the safety and effectiveness of NasoVAX in preventing worsening of symptoms and hospitalization in patients with early COVID-19.

This is an Early Feasibility Study (EFS) investigating the use of the Hemopurifier® in the treatment of SARS-CoV-2 Virus Disease (COVID-19).

The goal of this study is to evaluate the safety and effectiveness of Coronavirus-90 (COVID-19) convalescent plasma for the treatment of COVID-19. Plasma is the liquid part of blood that is left when all the blood cells have been removed. Convalescent means it is taken from people who were infected with COVID-19 and recovered. The use of this blood product to treat COVID-19 is investigational, which means the U.S. Food and Drug Administration has not yet approved it to be sold commercially. This is a human blood product collected by licensed blood banks. Donors of COVID-19 convalescent plasma must meet all standard blood donor criteria and must also meet all criteria set by the FDA for being a donor of COVID-19 convalescent plasma. A total of 500 patients will take part in the study at 8 hospitals within Beaumont. Similar studies are being done at other centers, but they are not directly related to this study. Participants will be assigned to a study group depending on how sick they are. Group A: Those who require more than 6 liters (L) of supplemental oxygen but are not on a ventilator Group B: Those who require a ventilator to preserve their life. Both groups will receive one unit (approximately 200ml or just under 1 cup) of COVID convalescent plasma. The transfusion will be given over about 30 minutes via an IV. Blood samples will be taken prior to and one hour after the transfusion to measure participant antibodies against Severe Acute Respiratory Syndrome-Coronavirus 2 (SARS-CoV-2) and a nasopharyngeal swab (deep in the nostril) will be taken to test for presence of the SARS-CoV-2 virus. One hour after the transfusion a blood sample will be taken to measure antibody levels to determine if the plasma caused the antibody level to rise. Similarly, blood samples will be taken to measure antibodies against SARS-CoV-2 and a nasopharyngeal swab will be taken to test for presence of the SARS-CoV-2 virus 1, 3 and every 7 days after the transfusion while the participant is in the hospital The participant's final health status will be determined on day 28. Hospital records will be monitored for 90 days after discharge to determine if the participant is readmitted to the hospital.
