Active clinical trials for "Severe Acute Respiratory Syndrome"

The purpose of this study is to collect blood from previously COVID-19 infected persons who have recovered and use it as a treatment for those who are currently sick with a severe or life-threatening COVID-19 infection.

Study Objective: To test if post-exposure prophylaxis with hydroxychloroquine can prevent symptomatic COVID-19 disease after known exposure to the SARS-CoV-2 coronavirus. To test if early preemptive hydroxychloroquine therapy can prevent disease progression in persons with known symptomatic COVID-19 disease, decreasing hospitalizations and symptom severity.

This study is intended to explore the possible protective role of anti-androgens in SARS-CoV-2 infection

To assess the safety and tolerability of inhaled molgramostim nebuliser solution in patients with COVID-19 pneumonia.

This protocol will serve as a platform for assessing treatments for adult patients hospitalized for medical management of COVID-19 without related serious end-organ failure. Trials will involve sites around the world strategically chosen to ensure rapid enrollment. This trial will compare hyperimmune intravenous immunoglobulin (hIVIG) with matched placebo, when added to standard of care (SOC), for preventing further disease progression and mortality related to COVID-19. SOC will include remdesivir unless it is contraindicated for an individual patient.

Background: Intra-alveolar clotting and alveolar collapse in ARDS is due to alveolar capillaries epithelial and leakage. Subsequently, collapse induces hypoxemia that is resistant to recruitment (RM). Heparin and Streptokinase may prevent or dissolve intra-alveolar fibrin clot respectively helping alveolar re-expansion. We examined and compared the effect of nebulizing Heparin versus Streptokinase on reversing this pathology. Methods: Sixty severe ARDS (PaO2/FiO2<100) patients and failure of RM, prone position (PP) and neuromuscular block (NMB) were partially randomised into Group (I): (n=20) received nebulized Heparin 10000 IU/4h. Group (II): (n=20) received nebulized Streptokinase 250,000 IU/4h. Group (III): (n=20) received conservative management. Randomization to either Heparin or Streptokinase groups was applied to patients whom guardian accepted participation, while those who declined participation were followed-up as a control. The primary outcome was the change in PaO2/FiO2; the secondary outcomes included the change in compliance, plateau pressure, ventilation-off days, coagulation and ICU mortality.

Severe and critically ill patients will be enrolled in the study (50 patients) after duly filled consent forms. Recipients shall be divided in to 5 groups with 10 patients per group to compare clinical efficacy and safety of patients in clinical phase I/phase II study. Each group shall receive particular single dose of Intravenously administered Immunoglobulins (IVIG) developed from convalescent plasma of recovered COVID-19 individual , an experimental drug along with standard treatment except for control group which will receive standard treatment only.

Double blinded randomized clinical trial designed to evaluate the security and efficacy of hydroxychloroquine as treatment for COVID-19 severe respiratory disease. The investigators hypothesize that a 400mg per day dose of hydroxychloroquine for 10 days will reduce all-cause hospital mortality in patients with severe respiratory COVID-19 disease.

In December 2019, the Municipal Health Committee of Wuhan, China, identified an outbreak of viral pneumonia of unknown cause. This new coronavirus was called SARS-CoV-2 and the disease caused by that virus, COVID-19. Recent numbers show that 222,643 infections have been diagnosed with 9115 deaths, worldwide. Currently, there are no approved therapeutic agents available for coronaviruses. In this scenario, the situation of a global public health emergency and evidence about the potential positive effect of chloroquine (CQ) in most coronaviruses, including SARS-CoV-1, and recent data on small trials on SARS-CoV-2, the investigators intend to investigate the efficacy and the safety of CQ diphosphate in the treatment of hospitalized patients with severe acute respiratory syndrome in the scenario of SARS-CoV2. Preliminary in vitro studies and uncontrolled trials with low number of patients of CQ repositioning in the treatment of COVID-19 have been encouraging. The main hypothesis is that CQ diphosphate will reduce mortality in 50% in those with severe acute respiratory syndrome infected by the SARS-COV2. Therefore, the main objective is to assess whether the use of chloroquine diphosphate reduces mortality by 50% in the study population. The primary outcome is mortality in day 28 of follow-up. According to local contingency plan, developed by local government for COVID-19 in the State of Amazonas, the Hospital Pronto-Socorro Delphina Aziz, located in Manaus, is the reference unit for the admission of serious cases of the new virus. The unit currently has 50 ICU beds, with the possibility of expanding to 335 beds, if needed. The hospital also has trained multiprofessional human resources and adequate infrastructure. In total, 440 participants (220 per arm) will receive either high dose chloroquine 600 mg bid regime (4x150 mg tablets, every 12 hours, D1-D10) or low dose chloroquine 450mg bid regime (3x150mg tablets + 1 placebo tablet every 12 hours on D1, 3x150mg tablets + 1 placebo followed by 4 placebo tablets 12h later from D2 to D5, and 4 placebo tablets every 12 hours, D6-D10). Placebo tablets were used to standardize treatment duration and blind research team and patients. All drugs administered orally (or via nasogastric tube in case of orotracheal intubation). Both intervention and placebo drugs will be produced by Farmanguinhos. Clinical and laboratory data during hospitalization will be used to assess efficacy and safety outcomes.

In December 2019, a new virus emerged in Wuhan, China rapidly becoming a pandemic with registered cases above 800,000 around the world. The virus is now known as SARS-CoV2 calling its disease coronavirus-19 or COVID-19. The mortality of the virus has been reported around 2-10% and its causes because of the proinflammatory immune response generated on the host. The cytokines involved in the immune response to COVID-19 are IL-1, IL-2, IL4, IL-6, IL-10, IL-12, IL-13, IL-17, GCSF, MCSF, IP-10, MCP-1, MIP-1α, HGF, IFN-γ y TNF-α. Ruxolitinib is an inhibitor of JAK 1/2 which is responsable for multiple cellular signals including the proinflammatory IL-6. Ruxolitinib works as and immunomodulator decreasing the cytotoxic T lymphocytes and increasing the Treg cells. This study is intended to stop the disregulated immune response caused by COVID-19 that generates the pneumonia and subsequent severe acute respiratory syndrome.
