Active clinical trials for "COVID-19"

Phase II/Phase III study to evaluate the safety and efficacy of Ramatroban 75 mg tablet against Placebo in subjects hospitalized for pneumonia due to SARS-CoV-2 infection. Approximately 324 eligible subjects will be randomized in a 1:1 ratio to one of the two treatment groups. Group I: Ramatroban 75 mg tablet + Standard of care; Group II: Placebo + Standard of care. Phase 2 Primary Objective: To evaluate the safety of Ramatroban 75 mg tablet with the standard of care against Placebo with the standard of care in COVID-19 hospitalized subjects. Secondary Objective: To assess the efficacy of Ramatroban 75 mg tablet with the standard of care against Placebo with the standard of care in COVID-19 hospitalized subjects. Phase 3 Primary Objective: To evaluate the efficacy of Ramatroban 75 mg tablet with the standard of care against Placebo with the standard of care in COVID-19 hospitalized subjects. Secondary Objective: To evaluate the safety of Ramatroban 75 mg tablet with the standard of care against Placebo with the standard of care in COVID-19 hospitalized subjects. Long COVID [Follow-up Phase- Objectives- (Phase 2 & 3)] To examine lipid mediators, specifically thromboxane A2, prostaglandin D2, F2-isoprostane and/or their metabolites in convalescent subjects after treatment. To assess the efficacy of Ramatroban administered during the acute illness in preventing/mitigating subsequent development of long COVID / PASC

This research is being done to collect preliminary data on the potential of computerized "brain-training" exercises for treating Long COVID symptoms in older adults. The investigators hypothesize that computerized brain-training will be an acceptable and feasible intervention for treating Long COVID symptoms in older adults. The investigators also expect to provide initial evidence that computerized brain-training has potential for improving thinking, mood, and other aspects of everyday functioning in older adults with Long COVID.

The COVID-19 is closely related to severe acute respiratory syndrome (SARS) with direct and indirect effects on several systems, especially the musculoskeletal system, in addition to the respiratory system. Some of these symptoms persist for a long time, called Post-COVID-19 Syndrome, directly interfering with the functional capacity and quality of life of these patients. Pilates exercises focus on breathing, postural symmetry, trunk stabilization, flexibility, joint mobility and strengthening through the full range of motion of all joints and not isolated muscle groups. The objective of this study will be to evaluate the clinical and functional effects of a Pilates for patients post hospitalization for COVID-19. A randomized and controlled clinical trial will be conducted, with recruitment patients who have developed the severe form of COVID-19 and required at least 7 days of invasive mechanical ventilation. They will be previously randomized in a 1:1 ratio by electronic system and blindly allocated to the intervention group that will perform an exercise protocol based on the Pilates method, 2x/week, for 12 weeks in therapeutic sessions of identical protocols lasting 60 min. All patients will be evaluated before and after for six minutes walk distance test, peripheral and respiratory muscle strength and endurance, post-COVID-19 functional status, dyspnea, and quality of life. The analysis will be based on intention-to-treat principles. Descriptive statistics will be used to present the characteristics of participants in the two treatment groups. P values less than 0.05 will be considered to indicate statistical evidence of significance. The variables of dyspnea, peripheral and respiratory muscle strength, functional capacity, post-COVID functional status and HRQoL will be analyzed using linear models of repeated measures which included all values measured after randomization with baseline scores and treatment clusters as covariates. Adjusted mean differences will be tested 12 weeks after randomization and start of intervention. Multiple comparisons will be performed using the Tukey Test with p-values adjusted using the Holm procedure. Baseline variables will be evaluated as predictors and moderators of treatment effects, including terms and interaction models. Effect sizes for primary and secondary endpoints will be calculated as Cohen's d from estimated marginal means (SMD) and standard error estimates from the adjusted primary analysis. All analyzes were performed using RStudio version 0.99.486. Results: The expected results are based on the alternative hypothesis that Pilates exercises are clinically effective, improving functional performance, exercise tolerance, reducing symptoms and improving the quality of life of patients with symptoms of Post-COVID-19 Syndrome.

The COVID-19 pandemic has become a major public health challenge, and the treatment options for the disease are currently limited. The commonly used oral small-molecule anti-COVID-19 drugs in China are Nirmatrelvir-Ritonavir and Azvudine. These drugs have been tested in pre-marketing clinical trials in patients with non-severe COVID-19 infection and have demonstrated therapeutic effects in inhibiting virus transmission and preventing disease progression. However, until now, the efficacy and safety of these drugs in patients with moderate to severe COVID-19 infections remains unclear. Therefore, this study is aiming to compare the efficacy and safety of Azvudine and Nirmatrelvir-Ritonavir in moderate to severe COVID-19 infections. This study will be a multicenter, randomized, controlled clinical trial study in patients hospitalized with moderate to severe COVID-19 infections. Recovery of clinical symptoms, nucleic acid negative conversion, improvement in oxygenation index, and imaging improvement will be used as study endpoints.

A randomized, double-blind, placebo-controlled phase II clinical study to evaluate the efficacy and safety of WPV01 in patients with mild/moderate COVID-19 infection

The goal of this type of clinical trial is to learn about symptomatic patients with post-COVID-19 parenchymal lung abnormalities. The main questions it aims to answer are: the efficacy and safety of low-dose dexamethasone or traditional Chinese medicine in symptomatic patients with post-COVID-19 parenchymal lung abnormalities. Participants will be divided into three parallel groups：controlled group with conventional western medicine treatment including oxygen therapy, antibiotics, nebulization therapy, etc. dexamethasone group: dexamethasone 1.5mg/day for one week and 0.75mg/day for another week basing on conventional western medicine. Chinese medicine group: Strengthening spleen and tonifying lung decoction for 2 weeks basing on conventional western medicine.

The aim of this study is to evaluate the efficiency and safety of immunoadsorption for the treatment of post-COVID syndrome (PCS). Efficacy will be measured (1) subjectively as an improvement of the score of questionnaires like the multidimensional fatigue inventory (MFI-20), Chalder fatigue scale, Bell-score, modified medical research council dyspnea scale (mMRC) and the Post-COVID functional scale (PCFS) and (2) objectively as an improvement in neurocognitive testing with the Montreal cognitive assessment (MoCA) and the improvement of the hand-grip strength. 40 participants with symptoms of PCS and a PCFS score of at least 2 will be included. After an exclusion of other causes of the symptoms and evaluation of the baseline burden of symptoms each participant will undergo 5 sessions of immunoadsorption with an immunoglobulin-binding adsorber and 5 sham-treatments or vice versa. The order of treatments (immunoadsorption first or sham first) will be randomized. Each participant will be blinded for the modality of the conducted treatment. A therapy-free period of 8 weeks will separate the two treatment blocks. All examinations will be conducted before the first treatment, 2 weeks after the first treatment cycle, before the second treatment cycle as well as 2 and 6 weeks after the second treatment cycle. The results of the study will inform future treatment strategies for PCS and will contribute to a better understanding of the pathophysiological insights behind the ongoing symptoms.

This is a prospective, single-center, open and self-controlled study.The purpose of this study is to evaluate the efficacy and safety of Paxlovid for the treatment of COVID-19 patients with severe chronic kidney disease.

Despite the greater risk of adverse COVID-19 outcomes, antibody and cell-mediated immune responses to COVID-19 vaccines vary amongst immunocompromised (IC) people and are poorly defined. IC hosts were largely excluded from the COVID-19 vaccine registration trials, though many countries recommend additional and booster doses of vaccination in this group. BOOST-IC is an adaptive randomised clinical trial (RCT) to assess the immunogenicity and safety of additional COVID-19 vaccine doses in immunocompromised (IC) people, including people with HIV, solid organ transplants (SOT) recipients or those with haematological malignancies. Briefly, the study aims to generate high-quality evidence on the immunogenicity and safety of alternative COVID-19 booster strategies against SARS-CoV-2 for IC people in Australia.

The purpose of the study is to evaluate whether bemnifosbuvir (BEM) is effective and safe in adults with COVID-19 who do not need to be in the hospital but who are at high risk for progression to severe disease. Eligible subjects will be randomly assigned (by chance) to receive BEM or matching placebo orally for 5 days. Co-administration of locally available standard of care (SOC) is allowed. The total duration of the study is 60 days.
